2.1 Introduction

Biomass store solar energy in the chemical form and it is most precious and versatile resources on earth. Biomass, unlike fossil fuels, is a renewable energy resource that is available where the climatic conditions are favorable for plant growth and production¹. The term biomass is used for all organic materials which are combustible in nature, mainly plant and animal origin present in land and aquatic environments. Biomass is considered carbon neutral, because the amount of carbon it can release is equivalent to the amount it absorbed during its life time. There is no net increase of carbon to the environment in the long term when combusting the lignocellulosic materials. Therefore, we can say that biomass is a renewable source of energy and can play vital role in responding to concerns over the protection of the environment and the security of energy supply^2,3.

Biomass energy accounts for about 15% of the world’s primary energy consumption and about 38% of the primary energy consumption in developing countries⁴. Furthermore, biomass often accounts for more than 90% of the total rural energy supplies in developing countries⁵. It is the main source to meet out domestic energy in developing countries⁶. The efficient use of fuel wood is much more eco-friendly than the use of efficient and conventional fuels like kerosene and liquefy petroleum gas (LPG). LPG emits 15 times more CO₂ per kg than wood, and kerosene emits nearly 10 times as much. CO₂ is the prominent candidate for global. It is commonly assumed that biomass fuel cycles based on renewable in nature and greenhouse-gas (GHG) neutral because the combusted carbon in the form of CO₂ is soon taken up by re-growing vegetation⁷.

3.1 Introduction

Nature has a provision for destroying and disposing off wastes and dead plants and animals. This decay or decomposition is carried out by tiny micro-organisms called bacteria. Making of farm-yard manure (FYM) and compost is also through decomposition of organic matter (OM). When a heap of vegetable or animal waste and weeds etc., die or decompose at the bottom of backwater or shallow lagoons, bubbles can be noticed rising to the surface of water. Sometimes these bubbles burn with dancing flame at dusk. This phenomenon has puzzled man for a long time. It was only during the past hundred years that Scientists unlocked this secret as the decomposition process. The gas thus produced was and is still called “Marsh Gas.” The technology of harnessing this gas under artificially created conditions is known as Biogas Technology.

4.1 Introduction

Biomass is referred to as an indirect source of solar energy and considered a source of stored chemical energy. Biomass is renewable organic material derived from plants and animals serving as sources of energy. Biomass produced from agricultural sector is big challenges for all over the world due to its improver disposal. Mitigating greenhouse gas emissions and ensuring adequate global food supplies represent two of the last decade’s mostdifficult challenges.Although global food production has benefitted from chemical fertilizers, environmental problems have emerged as a result of their use. Additionally, overuse of fertilizers can result in hardened soil, decreased soil fertility, polluted air and water, and the release of greenhouse gases. There is an urgent need to find an alternative to chemical fertilizers that, ideally, can be sourced in abundant amounts, promotes global food production, enhances CO₂ capture , and does not affect soil health or damage the environment¹. To sustain agricultural productivity, it is crucial to maintain adequate levels of organic matter in the soil to preserve its physical, chemical, and biological integrity. Biochar, a pyrogenic black carbon, may play an important role in improving soil health, resulting in higher crop yield and absorbing atmospheric carbon dioxide. Biochar is the most auspicious straw management measures and have highest carbon abatement and economic profit².

Biochar is produced by heating biomass at high temperatures (300 – 600 °C) in a closed reactor containing no to partial levels of air. Under these conditions, biomass undergoes thermo-chemical conversion into biochar. Because of its numerous potentials uses in agriculture, energy, and the environment, much attention has been given to biochar in both political and academic areas. Biochar can be used in a variety of applications such as energy production, agriculture, carbon sequestration, waste water treatment, and bio-refinery; additionally, biochar provides an alternative strategy for managing organic waste. These advantages have renewed the interest of agricultural researchers in producing biochar from bio-residues and using the product as a soil amendment.

5.1 Introduction

Today, energy distribution and environmental issues have developed into international threats. Demand for alternative fuels increases every day due to rapid population growth, rising living standards, and economical sustainability. With its massive population, India has become the fourth largest energy consumer country in the world after the United States, China, and Russia. Because most nations use fossil fuels to fulfill their energy demands, they create negative impacts on the environment including raising global temperatures, pollution, acid rain, and other effects. As such, the quest for alternative fuels derived from renewable resources has captured significant attention throughout the world¹. Biomass as a renewable energy sources is an important asset for achieving economic development is due to the availability of biomass at a low cost, a good conversion efficiency, the addition of jobs, and an increase in the biodiversity^2,3. Typically, biomass is composed of cellulose (40-50%), hemicelluloses (25-35%), and lignin (15-30%). Large amount of resources for biomass are available such as woody biomass, crop residues and their by-products, food processing waste, municipal solid waste, aquatic plant etc.

In the present context, pyrolysis process has been received a remarkable identity as a potential method for the conversion of any organic biomass into valuable energy rich products due to its simple in operation and also required a reasonable cost for conversion process. Pyrolysis is the thermal decomposition of any organic material at a specific temperature in absence of air/oxygen; the process ends with three resulting products, namely liquid (bio-oil), solid (biochar), and syngases⁴. Recently, biooil produced through pyrolysis process and further it up grading has been attracted a significant attention due to its major use as biofuel and as a precursor material for making chemicals⁵. The pyrolysis process also classified in three different types as per its operating conditions; slow, fast and flash pyrolysis.

6.1 Introduction

Torrefaction is a thermophilic process of biomass conversion into a solid, friable, homogenous coal-like material, which has better fuel characteristics than the original biomass. Torrefaction involves the heating of biomass material in the absence of air at 250 to 300°C temperature. Torrefaction produces high-grade hydrophobic nature solid biofuels from various streams of woody biomass or agro residues.Torrefied biomass has high energy density then the original biomass which make torrefied biomass as renewable alternate source for power generation in coal power plant. Torrefied biomass being hydrophobic in nature can be stored easily for longer duration with negligible biological degradation. At 250-300°C temperature volatilization has been taking place and around 30% mass of the biomass is reduced as compared to original untorrefied biomass with net energy loss of approximately around 10%.The end product is a predictable, homogeneous, hydrophobic, high value solid biofuel with far higher energy density and calorific value than the original biomass feedstock. During the torrefaction process a combustible gas is released, which can also utilised to provide heat to the process. The process diagram of torrefaction process is shown in Fig. 6.1.

7.1 Introduction

Biomass gasification is age old technology originated in 1800 century for lighting and cooking purposes (Sansaniwal et al., 2017). Biomass typically contents biopolymers such as cellulose, hemicellulose and lignin in addition to the presence of average composition of C₆H₁₀O₅ which depends upon physical characteristics of biomass¹. Oxygen is required for combustion of every fuel. For complete combustion of biomass stoichiometric air to fuel ratio required varies from 6:1 to 6.5:1 with CO₂ and H₂O as end product.

Biomass gasification is an efficient and environmentally friendly way to produce energy². Gasification process is nothing but it is a conversion of solid fuel into gaseous fuel for wide applications. This whole process completed at elevated temperature range of 800-1300 ^oC with series of chemical reaction that is why it come under thermo chemical conversion³. Thermo chemical processes are most commonly employed for converting biomass into higher heating value fuels⁴. Major thermal conversion route is include direct combustion to provide heat, liquid fuel and other elements to generate process heat for thermal and electricity generation is summaries in Fig. 7.1.

8.1 Introduction

Rising petroleum prices, increasing threat to the environment from exhaust emissions and global warming have generated an intense international interest in developing alternative non-petroleum fuels for engines. The use of vegetable oil in internal combustion engines is not a recent innovation. Rudolf Diesel (18581913), creator of the diesel cycle engines, used peanut vegetable oil to demonstrate its invention in Paris in 1900. In 1912, Diesel said, “The use of vegetable oils as engine fuel may seem negligible today. Nevertheless, such oils may become, in the passing years, as important as oil and coal tar presently.” Nowadays, it is known that oil is a finite resource and that its price tends to increase exponentially, as its reserves have being decreasing¹.

India ranks sixth in the world in total energy consumption and needs to accelerate the development of the sector to meet its growth aspirations. The country, though rich in coal and abundantly endowed with renewable energy in the form of solar, wind, hydro and bio-energy has very small hydrocarbon reserves (0.4 % of the world’s reserve). India, like many other developing countries, is a net importer of energy, more than 25 percent of primary energy needs being met through imports mainly in the form of crude oil and natural gas. The rising oil import bill has been the focus of serious concerns due to the pressure it has placed on scarce foreign exchange resources and is also largely responsible for energy supply shortages. The sub-optimal consumption of commercial energy adversely affects the productive sectors, which in turn hampers economic growth².

9.1 Introduction

The rapid growth of industrialization and population significantly affect on the demand of ethanol as an alternate fuel. Generally, conventional crops like sugarcane and corn become unable to meet the demand of bioethanol, due to their primary role in food and feed. Therefore, lignocellulosic biomass from agriculture waste is attractive precursor for bioethanol production. Biomass is renewable organic material, abundant and cost effective. Ethanol production from agriculture waste has been projected an economically attractive option for industrial sector. However, sugar and starch derived ethanol have a more theoretical yield as compared to lignocelluloses, theses sources are insufficient for bioethanol production. The major agricultural wastes including rice straw, corn straw, wheat straw and sugarcane bagasse etc. can subsequently used for ethanol production. Rice straw has a highest worldwide potential for bioethanol production (205 giga liter) followed by wheat straw (104 giga liter), corn straw (58.6 giga liter), and finally for sugarcane bagasse (51.3 giga liter)¹.

A bio fuels is environmentally friendly options for power generation. Most of the fossil fuels are biological in nature. These are plant forms that, typically, remove carbon dioxide from the atmosphere and give up the same amount when burnt. The bio fuels are therefore considered to be “CO₂ neutral”, not adding to the carbon dioxide level in the atmosphere. The type of bio fuel used will depend on a number of factor, chief amongst them being the available feedstock and the energy that can be used locally.

India import 70% of the oil it uses, and the country has been hard by the increasing price of oil, uncertainty and environmental hazards that are concerned with the consumption of fossil fuels. In this context, bio fuels constitute a suitable alternative source of energy for India. There are two examples of bio fuels are Ethanol and Bio diesel (Renewable Diesel)

Ethanol can be made from biomass material containing sugar, starches, or cellulose (starch and cellulose are complex from of sugar)

10.1 Introduction

Biomass fuels are a potential source of renewable energy. One of the major barriers to their widespread use is that biomass has a lower energy content than traditional fossils fuels, which means that more fuel is required to get the same amount of energy. When combined — low energy content with low density -the volume of biomass handled increases enormously. Compaction or densification is one way to increase the energy density and overcome handling difficulties.

Densification means compaction of loose material or to increase density of loose biomass so that its volumetric efficiency can be increased. Densification essentially involves two parts; the compaction under pressure of loose material to reduce its volume and to agglomerate the material so that the product remains in the compressed state. The resulting solid may be a briquette, a pellet and a cube. It will be briquettes if roughly, it has a diameter greater than 30 mm. Smaller sizes are normally termed pellets though the distinction is arbitrary. The process of producing pellets is also different from the typical briquetting processes. The densified product can be developed in the cubical shapes as well.

If the material is compacted with low to moderate pressure (0.2-5 MPa), then the space between particles is reduced. Further, increasing the pressure will, at a certain stage particular to each material, collapse the cell walls of the cellulose constituent, thus approaching the physical, or dry mass and more, density of the material. The pressure required to achieve such high densities are typically 100 MPa plus. This process of compaction is entirely depending on to the pressure exerted on the material and its physical characteristics including its moisture content.

Introduction

Horticulture is the science and art of propagation, production, utilization, improvement, harvesting and marketing of crops such as fruits, vegetables, ornamental plants, spices & condiments, medicinal & aromatic plants, plantation crops, postharvest technology etc. The term is derived from the Latin word hortus mean garden and cultura means to cultivate. These crops are diverse which includes annuals to perennials, edible to ornamentals, temperate to tropical, humid to desert, etc. Horticultural plants help to sustain and enrich people by providing nutritious food, medicines, enhances the beauty of surroundings, besides reducing carbon footprint. They also serves as raw material for various industries, such as processing, pharmaceutical, perfumery and cosmetics, chemical, confectionery, oils and paints, etc.

Importance of Horticultural Crops

The horticulture crops are a source of variability in farm produce as well as human diets. The comparative production per unit area of horticultural crops is much higher than field crops. They are not only a source of nutrients, vitamins, minerals, flavour, aroma and dietary fibres, but also contains health benefiting compounds and medicines. Ornamental horticulture have aesthetic value and protects the environment. These crops are also useful for cultivation in wasteland, poor quality soil, slopy, uneven or undulating lands. Mango and cashew nut are cultivated on a large scale in hilly and hill back areas. Such crops are of high value, labour intensive and generate employment throughout the year. Further they have national and international demand and are a good source of foreign exchange.

Biointensive IPM incorporates ecological and economic factors into agricultural system design and decision making while addressing public concerns about environmental quality and food safety. It provides suitable guidelines and options for the effective management of pests and beneficial organisms in an ecological context in a holistic self-sustaining manner. The flexibility and environmental compatibility of the Biointensive IPM strategy make it useful in all types of cropping systems particularly in an agro-biodiversity rich ecosystem.

Introduction

Litchi (Litchi chinensis Sonn), like most fruit tree crops, is usually attacked by two or three key pests, several secondary pests and a large number of occasional pests in localized areas where it is grown. Litchi is an important subtropical evergreen fruit crop belongs to family Sapindaceae. It is known as queen of the fruit due to its attractive deep pink/red colours and flavoured juicy aril (Singh et al., 2012).

Insect pest attacks on litchi, in China there are 193 species of litchi pests in two classes, 11 orders, and 57 families. In India, nearly 42 insects and mite species reported to attacking on trees and fruits of litchi at different stages of growth (Singh et al., 2012). The majority belong to the Lepidoptera and Coleoptera, followed by the Homoptera and Hemiptera. However, only about three or four key pests including fruit and flower borers, sucking bugs, stem borers and erinose mites which require regular control, and the species involved vary between orchards. Secondary pests viz., fruit-piercing moths, defoliators etc generally occur at sub-economic levels, but can become serious pests as a result of changes in cultural practices and litchi cultivars or because of indiscriminate use of insecticides against a key pest. Recently, litchi fruit borer and litchi leaf roller have acquired the status of major pests and now, litchi looper, litchi bug and bag worm are emerging pests of litchi (Choudhary et al., 2013; Singh et al., 2014). Occasional or incidental pests also can cause economic damage only in localized areas at certain times; the great majority of pests reported here fall within this last category.

Introduction

A symposium organized by the Food and Agricultural Organization (FAO) in 1966 and International Organization of Biological Control (IOBC) in 1967, felt the need for the development of a new concept called “Integrated control” which was later replaced by “Integrated Pest Management”. The origin of IPM was necessary after the serious failure of the chemical age which started in the 1940’s. The pesticides were used as the only tactic to completely annihilate the pests from the crop ecosystem, which did miraculously decreased the pests and increased the production of the crop extensively, but they failed to realize the balance of life, by nature and by virtue of the selection pressure pests started developing resistance against all kind of pesticides being dumped on them.While the pests were getting resistant, the dumped pesticides were accumulating in the environment and biomagnifying inside the bodies of animal (WHO, 1990; Alewu & Nosiri, 2011; Eskenazi et al., 1999). The indiscriminate use of pesticides led to the significant health hazard to the humans (WHO, 1990; Alewu & Nosiri, 2011; Sanborn et al., 2007; Mnifet al; 2011; Semchuk et al., 1992; Goad et al., 2004; McKinlay et al., 2008; Gasnier et al., 2009; Lin et al., 2015; Waddell et al., 2001), reproductive malfunction in male (Jamal et al., 2015), nervous system (Jaga and Dharmani, 2003; Rosenstock et al., 1991; Wesseling et al., 2002; Eskenazi et al., 2006), cardiovascular system (Hung et al., 2015) and ultimately death (WHO, 1990; Gunnell et al., 2007). From the lessons acquired of the hazards, the concept of IPM proposed the concept of “pest eradication” was replaced with “pest management”. There are more than 64 definitions of IPM but the most accepted one came from FAO (1967) which defined IPM as “a system in context with associated environment and the population dynamics of pest species, utilizes all suitable techniques and methods in as compatible manner as possible and maintains the pest populations at level below those causing economic injury”. IPM decreased the pest pressure of the crop and increased the productivity of the crop and income of the farmers. IPM is a complex approach that advocates the integration of several components such as physical, mechanical, biological, legal, ecological and chemical tactics, in a compatible manner in a complete ecological set up, so that natural mortality has a role in checking the pest population building up above economic injury level (EIL).

Introduction

Banana (Musa sp; family: Musaceae) is the second most important fruit crop in India next to mango. Its year round availability, affordability, varietal range, taste, nutritive and medicinal value makes it the favorite fruit among all classes of people. It has also good export potential. Banana evolved in the humid tropical regions of South East Asia with India as one of its center of origin. Modern edible varieties have evolved from the two species – Musa acuminata and Musa balbisiana and their natural hybrids, originally found in the rain forests of S.E. Asia. During the seventh century AD its cultivation spread to Egypt and Africa. Banana and plantains are grown in about 120 countries. Total annual world production is estimated at 86 million tonnes of fruits. India leads the world in banana production with an annual output of about 14.2 million tonnes. Other leading producers are Brazil, Eucador, China, Phillipines, Indonesia, Costarica, Mexico, Thailand and Colombia. In India banana ranks first in production and third in area among fruit crops. It accounts for 13% of the total area and 33% of the production of fruits. Production is highest in Maharashtra (3924.1 thousand tones) followed by Tamil Nadu (3543.8 thousand tonnes). Within India, Maharashtra has the highest productivity of 65.70 metric tones /ha. against national average of 30.5 tonnes/ha. The other major banana producing states are Karnataka, Gujarat, Andhra Pradesh and Assam.

Pomegranate (Punica granatum L.) also known Anar in Hindi it is belonging to the Punicaceae family, it is grown in tropical and sub-tropical regions. Originated in Indo-Burma region Iran and is extensively cultivated in the Mediterranean region since ages (Sheikh and Manjula, 2009). Pomegranate is used as table purpose, making juice, jam, jelly and paste. The fruit peel, tree stem and leaves and root bark are good source of secondary metabolites such as tannins, dyes and alkaloids (Mirdehghan and Rahemi, 2007). The edible part of the fruit is the seeds having a fleshy covering and called arils.

India is major pomegranate producing country in the world. In India main pomegranate producing states are Maharashtra, Karnataka, Gujrat, Andhra Pradesh, Madhya Pradesh, Tamil Nadu and Rajasthan. Maharashtra is leading state of pomegranate production in India. The prominent pockets where pomegranate cultivated area are concentrated are Solapur, Nashik, Sangli, Satara and ahemednagar districts of Western region of Maharashtra.

Indian total pomegranate crop covers 0.24 Mha and production is 2.87 MT in India (Anonymous 2017). The export of pomegranate from India is only 0.04 MT it is very low. Pomegranate is majorly exported to UAE (43%), Bangladesh (16%) and European Countries (14%) A few tons also go to Saudi Arabia, Russia, Thailand, Nepal, Kuwait etc.

Introduction

Papaya is a tropical tree fruit crop that cannot tolerate freezing temperatures. It has commercial importance because of its high nutritive and medicinal value. Papaya cultivation had its origin in South Mexico and Costa Rica. Total annual world production is estimated at 6 million tonnes of fruits. India leads the world in papaya production with an annual output of about 3 million tonnes. Other leading producers are Brazil, Mexico, Nigeria, Indonesia, China, Peru, Thailand and Philippines. Papaya fruit are borne on peduncles attached to the main trunk of the papaya tree and are clustered, starting a few feet above the ground and extending up to a foot below the top of the plant adequate water is essential to the uninterrupted growth and production of papaya fruit. There is number of factors which affect quality and quantity of papaya production. Out of insect pest is one of the important factors to reduction of papaya fruit production. List of insect pests of papaya given as below:

Introduction

The guava fruit is a good source of vitamin C, pectin, calcium and phosphorus. The fruit is used for the preparation of processed products like jams, jellies and beverages. Guava jelly puree is very popular for its attractive purplish-red colour, pleasant taste and aroma. The puree can be used in juice, cakes, puddings, sauces, ice-cream, jam and jelly. Fruits can be preserved by canning as halves or quarters, with or without seed core (shells). Good quality salad can be prepared from the shell of ripe fruits. Their cultivation in India about 1.32 lakh ha area with production is 17.12 lakh tonnes. Biointensive pest management is use to major emphasis on conservation and enhancement of natural enemies and utilization of all compatible methods for achieving effective economical and safe pest control. These methods are the most appropriate in horticulture and in protected cultivation. The major aim of Biointensive pest management is to provide guidelines and options for the effecting management of pests and beneficial organisms in an ecological context. It will help to reduce the dependence on chemical pesticides and ecological deterioration. Biointensive pest management includes bio-pesticides derived from microbes, parasitoides, predators, botanicals and all conventional non-chemical methods or use of need based. Large number of insect pests has been reported to occur on guava at various growth stages. More than 80 species of insects and mites have recorded on affecting the growth and production. About three species of fruit flies, Bactrocera dorsalis, B. Cucurbitae and B. Zonata found to attack guava fruits, B. Dorsalis being the dominant. Maximum activity of fruit flies is observed during August to December reaching its peak during September. Two species of bark eating caterpillars, Indarbela quadrinota and I. Tetraonis are commonly found in the region. Sucking pests included Mealy scale, Chloropulvinaria psidii, Mealy bugs Ferrisia virgata, Plannococcus citri, Tea mosquito bugs, Helopeltis antonii, aphid, jassids etc (Azad Thakur et al., 2009). The major pests of guava that are economically damage on this crop given below:

Introduction

Agricultural pests cause considerable yield losses throughout the world. In ancient times, farmers had to manage pest problem to safeguard their basic needs, and as a response, the farmers use to practice and develop cultural and mechanical pest control strategies based on their field experience. Over a period of time, these practices have become a part of their production management system. Pest management practices began to change in later stages of the 18^th century. Introduction of pesticides in agricultural ecosystems 1950’s contributed substantially in raising agricultural productivity and they become an integral component of intensive agricultural ecosystems. At the same time, environmentalists raised their concerns on deleterious effects of pesticides on environment, human health and non-target organisms. Excessive use and abuse of pesticides leads to the problems like resistance, resurgence and residues (Beaument, 1993). One of the deleterious effects of over use of pesticides is the death of effective predator and parasitoids. This ultimately leads to the imbalance in the agroecosystem. Concerns about the negative effects of pesticides led to research and promotion of alternative pest control practices – Integrated Pest Control or simply IPC. This new concept called Integrated Pest Control (IPC) and later Integrated Pest Management (IPM) was stimulated by symposia organized by the Food and Agriculture Organization (FAO) of the United Nations in 1966 and the International Organization for Biological Control (IOBC) in 1967. IPM made a paradigm shift in the philosophy of pest control, from pest eradication to pest management. Instead of single tactic control, emphasis was placed on the use of a combination of available tactics in a compatible manner keep the pest below economic injury levels. Consequently, a more integrated approach of pest control was advocated considering the natural mortality factors. IPM is a complex system approach that comprises judicious use of cultural, physical, mechanical, biological, host plant resistance, regulatory and chemical methods.

Introduction

Okra (Abelmoschus esculentus L. Moench) also known as lady’s finger or bhendi, belongs to family Malvaceae. Tender fruits are used as vegetables and thickening of gravies and soups, because of its high mucilage content. The roots and stems of okra are used for cleaning cane juice (Chauhan, 1972). In okra several pest may damage the tender fruit that leads to reduction in yield which can be controlled by holistic approach to develop sustainable agriculture. There are several ways among this the Biointensive integrated pest management (BIPM) is one of the best way to discourage the development of pest populations and keep pesticides free so that it makes economically justified to farmers, reduce risks to human health and the environment. Biointensive integrated pest management (BIPM) is essentially a component of integrated pest management which helps to reduce the dependence on chemical pesticides thereby preventing ecological deterioration. The major elements of this approach includes many factors viz., host plant resistance, use of beneficial organism, agronomic practices, biopesticides, parasitoids, predators, plant exudates etc.

Introduction

Brinjal is an important vegetable crop grown extensively throughout India. In India, brinjal is cultivated in around 730.4 ha with a production of 17.5 million tonnes in the year 2017-18. It is also called as poor man’s vegetable. It is consumed in variety of ways depending upon the eating habits of the different parts of the country. It is grown extensively in Bihar, Orissa, Karnataka, Tamil Nadu, Andhra Pradesh, Maharashtra, West Bengal, Uttar Pradesh and states with matching climatic conditions in the tropics and subtropics.

Brinjal is an important vegetable crop, but insect pests are making more losses in brinjal cultivation. In brinjal, more than 36 pests have been reported from the time of planting to harvest (Regupathy et al., 1997). Among all insect pests shoot and fruit borer (Leucinodes orbanalis), hadda beetle (Epilachna vigintioctopunctata), jassid (Cestius phycitis), Ash weevil (Myllocerus subfasciatus), white fly (Bemisia tabaci), lace wing bug (Urentius hystricellus) are important (Barker and Pritchrad, 1960).

Despite serious nature of the pest, its management tactics by and large is limited to frequent sprays of chemical insecticide without much impact on the yield. Such practice of pesticide usage is detrimental to environment, also increases the cost of production and chances of insecticide residues in the fruit. About 47 per cent insecticides are used for management of fruit and shoot borer out of the total pesticide consumed in vegetables. In this background major emphasis, now-a-days, is being given on Biointensive integrated pest management as alternate to the insecticides for management of any pest. More than a dozen parasitoids and three pathogens have been recorded as natural enemies of insect pest. But the extent of parasitisation/predation under field condition is very low. In this context, inundative release of bio-agents, particularly egg parasitoids in pest management may be more advantageous.

Introduction

Cucurbits belong to the family cucurbitaceae; constitute the largest group of summer vegetables grown all over the world which includes about 118 genera and 825 species. Cucumbers, muskmelons, watermelons, squashes, gourds, luffagourd, tissel-gourd and pumpkins are commonly grown cucurbits are mostly important one. These crops are attacked by a variety of insect pest and diseases throughout its growth period; generate wounds that help to transmit of viral particles, bacteria and invasion of fungal pathogens. Major insect pests include cucumber beetles, red pumpkin beetles, fruit flies, epilachna beetles, squash bugs, aphids, white flies, squash vine borers, two-spotted spider mites, and nematodes affects significant damages from seeding stage upto harvest. Insect pest infestations in cucurbits bring about heavy losses through reduction in yield, lowered quality of produce, defoliation of leaves, damage roots or flowers, contribute to poor crop standard increased cost of production and harvesting besides expenditure incurred on materials and equipments to apply control measures.

Introduction

Tomato (Solanum lycopersicum) is the largest and most important vegetable crop belongs to family Solanaceae grown all over the world. It is grown for its edible, fleshy, berry typed, mostly red coloured fruits.The species has its origin in coast of Ecuador, Peru, part of Bolivia and the northern region of Chile i.e.western South America and cultivation started most probably by the people of Maxico of Central America^1-3. It is found to be a rich source of many minerals like Ca, K, Cu, Fe, Zn and S and vitamins and other nutritive values so it is cultivated both as protective and supplementary food⁴.In India and in some European countries with common form of tomato fruits the cherry type of tomato fruits also cultivated on large scale. Cherry type of tomato fruits when consumed fresh, act as a very efficient source of diet of urban and rural people as it is reported to be a good source of many macro elements of human requirements such as K, Mg, P and Na⁵. As it is short duration crop and gives high yield, it is important from economic point of view and hence area under its cultivation is increasing day by day. India is considered to be a second largest producer of tomatoes succeeding to China. Tomato is used in preserved products like ketch- up, sauce, chutney, soup, paste, puree etc. Cherry fruits are commonly used in diverse ways, including raw in salads and processed, and their acidity allows for ease of preservation without refrigeration (long shelf life) or home canning processing for later use⁶

Introduction

Potato (Solanum tuberosum) is the most important food crop of the world. Potato is a temperate crop grown under subtropical conditions in India. The potato is a crop which has always been the ‘poor man’s friend’. Potato is being cultivated in the country for the last more than 300 years. For vegetable purposes it has become one of the most popular crops in this country. Potatoes are an economical food; they provide a source of low cost energy to the human diet. Potatoes are a rich source of starch, vitamins especially C and B1 and minerals. They contain 20.6 per cent carbohydrates, 2.1 per cent protein, 0.3 per cent fat, 1.1 per cent crude fibre and 0.9 per cent ash. They also contain a good amount of essential amino acids like leucine, tryptophane and isoleucine etc.

Potatoes are used for several industrial purposes such as for the production of starch and alcohol. Potato starch (farina) is used in laundries and for sizing yarn in textile mills. Potatoes are also used for the production of dextrin and glucose. As a food product itself, potatoes are converted into dried products such as ‘potato chips’, ‘sliced’ or ‘shredded potatoes’.

Potato is grown almost in all states of India. However, the major potato rowing states are Himachal Pradesh, Punjab, Uttar Pradesh, Madhya Pradesh, Gujarat, Maharashtra, Karnataka, West Bengal, Bihar and Assam.

The main constraint to potato farming in India are: It is vulnerable to control the pests hence implying a high risk of failure, growing potatoes requires substantial capital and the crop needs intensive care and attention. However, a proper Biointensive insect pest management programme will minimize losses to potato crop.

Introduction

Chilli (Capsicum annuum var.annuum L.) is one of the most important economical and popular vegetable crops grown for its green fruits as vegetable and red one as a spice¹. It is a native of southern Texas and Maxico and was introduced in India by the Portuguese in 19^th century². Chilli is mainly used in culinary adding flavor, color, pungency and rich source of vitamins like A, C, E, P and having medicinal properties³. Chilli is one of the important cash crops grown in almost all parts of the country and is widely grown in the tropics and subtropics as also under glass houses in temperate regions⁴. The plants are very sensitive to excessive rainfall, water lodging and frost^2,5. The ideal condition for its cultivation are well drained loam soil rich in organic matter but can also be grown in many type of soils⁶. India is a major producer, exporter and consumer of chilli⁷. Chilli is presently grown extensively throughout the country, both under rainfed and irrigated conditions, in almost all the states covering an area of 792.1 thousand Ha with annual production of 1223.4 thousand metric tonnes⁸. Andhra Pradesh is the largest producer of chilli in India. It contributes about 30% to the total area under chilli, followed by Karnataka (20%), Maharashtra (15%), Orissa (9%), Tamil Nadu (8%) and other states contributing 18% to the total area under chilli⁸.

Introduction

Biointensive integrated pest management (BIPM) is essentially a component of integrated pest management which helps to reduce the dependence on chemical pesticides thereby preventing ecological deterioration. The major elements of this approach includes many factors viz. host plant resistance, use of beneficial organism, agronomic practices, bio pesticides, parasitoids, predators, plant exudates etc. It also includes all other conventional non-chemical methods of pest control like use of botanical insecticides preferably plant based insecticides like Azadirachtin from Neem (Azadirachta indica), Rotenone from Derris chinensis and Derris elliptica, Nicotine from Tobacco (Nicotiana tabacum), Juvocimene 1 or 2 and Ocimin from Ocimum sanctum, Atropine from Datura stramonium, Annonine and Squamocin from Annona squamosa etc.

Introduction

Medicinal plants are known to Indian traditional healers since time immemorial. The plants were collected from the wild and were used in many preparations of wellness products. India is endowed with diverse group of medicinal plants accounting for more than 8000 species which are being used in more than 10,000 herbal products. Ninety percent of herbal industry’s requirement of raw materials is meted out from the natural ecosystem-forests-resulting in ruthless exploitation and destruction of its natural habitats (Mathivanan et al., 2016). Medicinal plants are cultivated or found in the wild throughout the country and are used for various purposes including traditional herbal remedy (infusion, tincture and decoction) and extraction of phytochemicals for homoeopathic and ayurvedic drugs, cosmetics, neutraceuticals/dietary supplements, functional foods and aroma therapy oils (Nagpal et al., 2004). The large scale cultivation of medicinal plants may face the problem of sudden appearance of large populations of insect pests in a single crop. Like other plants, medicinal plants too have to bear the devastating effects of injurious insect-pests, which are not only harmful for the plant but also, deteriorate the quality of the produce, thus hampering its medicinal value.This chapter discusses major insect-pest and their eco-friendly measures in medicinal plants so that a package of practices can be recommended for an easy adoption even by small and marginal farmers and gardeners in India.

Introduction

Biotic stresses, particularly insect pests adversely affect the economical yield potential and the quality of the widely cultivated spice crops. These pests attack the crops at various developmental stages of the crops. For instance, Pollu beetle alone in black pepper is the most destructive pest and causing 30 to 40% yield loss in humid, tropical evergreen forests of India (Devasahayam, et al., 1988). Considering the cost of cultivation and profitability, it is very important to develop and recommend low cost, economic easily adoptable technologies. Food production process in India during the green revolution period has been based on the use of more chemical fertilizers and pesticides which are detrimental to the environment. The challenge before the crop protection scientists is to boost the yield from the available land without harming the environment. To manage the problem of insect pests in spice crops, farmers are over using synthetic chemical pesticides indiscriminately and this result in environmental degradation and high pesticide residue levels in the produces are are mainly hindering the export. Now the focus is on organic spice production, therefore a search for safer measures of pest and disease management is gaining importance. Integration of various approaches like use of resistant/tolerant varieties, disease or pest free planting materials and exploitation of biological means such as bio- control agents, bio-pesticides, entomo-pathogens, parasitoids and predators at the right time paved the way to achieve this goal (Dhanya et al., 2019; Prakash et al., 2016). Incorporating ecological and economic factors into decision making and addressing the public concerns about environmental quality and food safety is the need of the hour. There is now wide array of techniques available to replace the use of conventional chemical insecticides in IPM programmes. These issues can be sorted out by adopting eco-friendly Biointensive Integrated Pest Management strategy.

Introduction

Progress in plant biotechnological research has opened many avenues for basic and applied research in the field of crop plants. Plant tissue culture is an important component of biotechnology that involves in the improvement of crops. Besides this, plant tissue culture provides a good system for many basic studies in plant breeding, plant physiology, genetics and cell biology. Further, manipulation of cells through the modern technique of genetic engineering may lead to an introduction of new gene(s) to a host plant and the techniques of genetic engineering rely on plant tissue culture techniques. The regeneration of plants through plant tissue culture and their subsequent acclimatization and delivery to the field possesses many problems to make tissue culture technology a viable alternative proposition. The successful development of encapsulation technique for preparation of plant propagules in a nutrient gel has initiated a new line of research on artificial seeds. Application of this technology has been well recognized in several agronomically important crops and forest trees. Artificial seeds make a promising technique for propagation of transgenic plants, non-seeds producing plants, polyploids with elite traits and plant lines with problems in seed propagation.

2.1. LABORATORY SETUP

The setting up of a tissue culture laboratory needs proper planning. It depends on the nature of research works to be under taken and/or commercialization of tissue culture technology and the availability of space. The ideal tissue culture laboratory should have the following components:

1. Store facility for chemicals
2. Media preparation room
3. Autoclave room
4. Storage facilities for autoclaved laboratory-ware and media
5. Washing facilit
6. Culture room
7. Inoculation room
8. Instrumentation room
9. Hardening facility

To mimic the natural seeds, the embryos from cultures are encapsulated in a nutrient gel containing essential organic/inorganic salts, carbon sources, plant hormones and antimicrobial agents and coated completely to protect the embryos from mechanical damage during handling and to allow the development and germination without any undesirable variation. When looking at the history of synthetic seed technology, a wide number of encapsulating agents have been tested in time for their capacity to produce beads like, potassium alginate, sodium alginate, carregeenan, agar, agarose, guargum, polyox, gelrite, sodium pectate, carboxymethyl cellulose, nitrocellulose, ethylocellulose, polyethyleneamine (Kersulec et al., 1993), chitosane (Tay et al., 1993), tracanth gum etc. have been tested as hydrogels (Table 3.1), out of which alginate emasculation was found to be more suitable and practical for synthetic seed production. Some plants exudates of arabic (Acacia senegal), karaya (Stereculsia sp.), or seed gums of gaur (Cyamopsis tetragonoloba), tamarind (Tamarindus indica) or microbial products like dextran, xantham are also being used for encapsulation.

The artificial seed production technique was first used in clonal propagation to cultivate somatic embryos placed into an artificial endosperm and constrained by an artificial seed coat. Today artificial seeds represent capsules with a gel envelope, which contains not only somatic embryos but also axillary and apical buds or stem and root segments (Vdovitchenko and Kuzovkina, 2011).

The prime requirements for preparation of artificial seeds are high frequency somatic embryogeniccalli, synchronous embryo development and maximum conversion of embryos into plants. Success in production of synthetic seeds mainly depends on how best callus development and plantlet regeneration are achieved. However, over time the morphogenetic competence of differentiated cultures declines (Lynch and Benson, 1991). Therefore, the primary goal of synthetic seed production is to produce somatic embryos that resemble more closely to the true seed embryo in storage and handling characteristics so that they can be utilized as a unit for clonal propagation and germplasm conservation. Synthetic seeds may be hydrated or dehydrated and may be quiescent or not. Encapsulation of micropropagules enables to satisfy the requirements of synthetic seed development. The gelling agents used for encapsulation for production of synthetic seeds act as protective cover. The encapsulated synthetic seeds also contain growth nutrients, plant growth promoting microorganisms (mycorrhizah, Rhizobium, etc.), and/or other biochemical constituents necessary for optimal embryo-to-plant development (Fig. 4.1). Fungicides may also be used in the liquid gelling medium to protect them during storage and germination in vitro and in vivo.

As stated by Murashige’s definition, artificial seed (or synthetic/synseed) technology was initially restricted to species in which somatic embryogenesis was possible. Later, Bapat and co-workers (1987) proposed to broaden the technology to the encapsulation of various in vitro-derived propagules, and they used axillary buds of Morus indica as a first example of this new application. The new concept paved the way for the encapsulation of explants other than somatic embryos, and to the formulation of a new definition of artificial seeds (Aitken-Christie et al. 1995) as “artificially encapsulated somatic embryos, shoots, or other tissues which can be used for sowing under in vitro or ex vitro conditions”. In other words, the “new” artificial seed, lost the original bond of containing an embryo (zygotic or somatic), can now contain any kind of explant from tissue culture (such as axillary buds, shoot tips, nodal segments, bulblets, protocorms, callus samples, cells) which, following ‘germination’, will evolve into a plantlet or a shoot (artificial seed conversion) or will produce new cell proliferation (artificial seed regrowth).

Realization of synthetic seed technology requires manipulation of in vitro culture system for large-scale production of viable materials for preparation of synthetic seed, subsequently conversion into complete plants under in vitro as well as in vivo conditions. Somatic and gametic embryogenesis that enhanced axillary bud proliferation are the efficient techniques for rapid and large-scale multiplication of desirable plant species. Plant tissues such as somatic embryos, apical shoot tips, axillary shoot buds, embryogenic calli, and protocom-like bodies are potential micropropagules that have been considered for creating synthetic seeds. Encapsulations of somatic embryos, apical and axillary shoot buds, and regeneration of whole plants from them have been reported for a number of plant species (Redenbaug et al., 1986; Mathur et al., 1989; Ganapathi et al., 1992; Lulsdorf et al., 1993).

In fact, as the concept of synthetic seed involves the use of small propagules and enables the direct sowing of this material in vitro or in vivo, the technology could provide great flexibility to the breeders by not only reducing the costs when large quantities of propagules are required for handling, shipping and planting, but also eliminating the acclimation step when direct sowing in vivo is applied (Onishi et al. 1994).

The artificial seed technology has been applied to a number of plant species belonging to angiosperms. The exact application of artificial seeds will vary from species to species. In self-pollinated crops that currently have good seed production systems, synthetic seeds will not have any practical applications, but in cross pollinating species, especially those where seed production is difficult and expensive, synthetic seeds offer many advantages and opportunities. The importance of encapsulation technique as an aid to propagation in various crop plants has been discussed by many workers. By combining the benefits of vegetative propagation system with the capability of long-term storage and with clonal multiplication, synthetic seeds have many diverse applications in agriculture (Gray and Purohit, 1991; Redenbaugh et al., 1991; Redenbaugh, 1993). In some species seed propagation is not successful. The reason behind this may be due to heterozygosity of seed, small sized seed, presence of reduced or insufficient endosperm, and seedless varieties of crop species like grapes, watermelon, mango, guava etc. Sometimes association of mycorrhizal fungi is essential for seed germination, for example orchids. The germination of these seeds under natural conditions or under control environment is not possible. Propagating of these species through synthetic seed is the added advantage. The possible implications of synthetic seed technology have been detailed hereunder.

Plant tissue culture is mainly referred to as mass-multiplication of in vitro derived plantlets grown under controlled environment. Subsequently, the production of artificial seeds from in vitro grown plant propagules is also a method of mass-production of true-to-type plantlets. Micropropagation allows rapid and mass production of high quality, disease free and uniform planting material irrespective of the season and weather. Micro-shoots on being transferred to ex vitro conditions are exposed to abiotic (altered temperature, light intensity and humidity conditions) and biotic stress conditions i.e. soil micro-flora, so there is need for acclimatization for successful establishment and survival of plantlets (Deb and Imchen, 2010). In order to increase growth and reduce mortality in plantlets at the acclimatisation stage, research has been focused on the control of the environmental conditions (both physical and chemical) and to acclimatize the plants to compete with soil microflora (Mathur et al., 2008). In this chapter methods of acclimatization of plantlets derived from simple plant tissue culture or from synthetic seeds are discussed.

Many researchers successfully prepared synthetic seeds of crop plants. The major success of this technology is being elaborated in this chapter.

8.1. FIELD CROPS

Rice is the world’s most important food crop and a primary food source for more than one third of the world’s population. This crop has received considerable attention in biotechnology research progammes. Research in artificial seeds in rice is not scanty and this technology through somatic embryogenesis would offer a great scope for large-scale propagation of superior elite hybrids (Brar and Khush, 1994). However, success on artificial seeds research in field crops, especially cereals is still in infancy. However, many workers successfully encapsulated somatic and androgenic embryos of cereal crops (Datta and Potrykus, 1989; Suprasanna et al., 1996; Roy and Mandal, 2004 & 2008). Brar et al. (1994) emphasized the need for research on artificial seeds in rice through embryogenesis and outlined its impact on mass propagation of true-breeding hybrids. Somatic embryogenesis can also be used in the regeneration of genetically transformed plants (Vicient and Martinez, 1998). Subsequently those somatic embryos could be economically and successfully propagated though synthetic seed technology.

Artificial seeds have been widely used for micro-propagation of many plant species. Establishment of gene banks for ex situ conservation of plant germplasm in the form of field gene banks, seed gene banks, in vitro collections, and cryogenically preserved tissues is a common practice (Withers 1983; Rao, 2004; Borner, 2006). Alginate encapsulation provides a viable approach for in vitro germplasm conservation as it combines the advantages of clonal multiplication with those of seed propagation and storage (Standardi and Piccioni, 1998; Ara et al., 2000).

The main aim of artificial seeds is to obtain true to type plants to maintain the germplasm, but, however, during tissue culture, there is a chance of genetic aberration which is commonly known as somaclonal variations. Larkin and Scowcroft (1981) for the first time used the word ‘somaclonal variation’ to describe these variations as displayed among the plants derived from tissue culture. It is clearly understood that genomes modify themselves when exposed to unfamiliar conditions, and these modifications are best described as programmed loss of cellular control (Phillips et al., 1994).

Results of intensive researches in the field of synthetic seed technology seem promising for propagation of crop plants. However, as described in literature, the major stumbling block in establishing artificial seed production as a viable technology is a lack of understanding of the somatic embryo process and an inability to consistently produce high-quality propagules that can germinate in a soil environment with an acceptably high success rate7. Several aspects of the techniques are still underdeveloped and hinder its commercial application.

10.1. LACK OF STANDARD PROTOCOLS

The synthetic seed technology application in a commercial scale is still hampered by the low efficiency of the protocols and logistic behind it. Till today standard protocol for synthetic preparation is available for a limited number of plant species.

Micropropagation through artificial seeds may be commercially exploited on a large scale, generating millions of plantlets within a few days, and this may become a profitable multibillion rupees industry in near future. This technology would be feasible and even competitive economically with the other seed production methods.

In the near future, the synthetic seed technology could be the key to overcome these problems, e.g., through automated procedures of artificial seed production (Aitken-Christie et al. 1995) followed by autotrophic micropropagation (Jeong et al. 1995). The synthetic seed systems coupled with artificial intelligence and microcomputer systems like the most advanced robots, which can mimic the motions, and functions of living beings (i.e. automated encapsulations). It would tremendously increase the efficiency of encapsulation and production of artificial seeds, and revolutionized the plant propagation method in the years ahead. This technology is gradually moving towards the commercial propagation of high value crops. However, there is a great need for refinement of this technology by tackling of certain technical problems such as the need to produce high quality and high fidelity somatic embryos and to avoid the genetic instability and variability of tissue culture derived plants. The somatic variation can be overcome if the process and regulation of somatic embryogenesis and origin of somaclonal variation are well understood. The understanding about the storage, transport, handling growth habit and harvest index of artificial seeds is essential. The efforts are also needed to increase the output of embryos or plants per gram of callus tissue and conversion frequency of artificial seeds are also needed.

The artificial intelligence (AI) world is quickly growing as it reaches several different industries. You currently will see AI used for many different purposes from agriculture to automotive; with the passage of time you will see even more of it. Agriculture is one of the most important branches of the IT industry. Agriculture is an important industry and is a big part of our economy’s base. In terms of annual sales, the agricultural industry contributes to our economy almost 17%.AI is becoming a technical advancement that boost and protects crop yield, as climate change and populations rise. Here in this chapter basics of Artificial Intelligence have been discussed how it can be related to agriculture.

1. Introduction

Artificial Intelligence has become most prominent in current generation. Every field is utilizing Artificial Intelligence for their better results and which also result in saving a lot of time. As Artificial intelligence is boosting different sectors to increase the productivity and efficiency and its utilization across different sectors like in the field of CIVIL Artificial Intelligence can be used to analyze the structures of buildings, dams etc., and Artificial Intelligence solutions are assisting in so many ways to overcome the traditional challenges in every field.

I. What is Artificial Intelligence

Artificial Intelligence is one of the most prominent field of Computer Science Engineering which attempts to redefine the tasks which are carried out by humans in their daily life with better results and maximum accuracy. Artificial Intelligence is actually meant to ease the work of human where the word artificial states the work done without any human interference and intelligence states the capabilities like human brain to perform tasks. The field artificial Intelligence has given so many definitions from time to time which can be typically stated as

As we have seen how artificial Intelligence can be useful in agriculture but the nest question always come in mind is that from where and how we can start to learn and what are the model of learning an artificial Intelligence. As Artificial Intelligence is a huge part of Computer Science which means we need an language as medium to perform it and we always prefer Python for that which is very dynamic and easy to learn. In this chapter we will learn about python basics so that in further implementation of artificial Intelligence it will be helpful to us.

I. Introduction

Python is a remarkable language that can claim to be easy and strong. You will be amazed to see how simple it is not to focus on the language you are programming, but on solving the problem. Guido van Rossum was the creator of the Python language which is named after the BBC show “Monty Python’s flying Circus”.

Python is formally introduced as:

“Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.”

As we know there are different branches of artificial Intelligence and machine Learning of one of them which has become a most advance and widely used branch of artificial Intelligence in every field of this generation whether it may be either electronics, civil, mechanics, Bioengineering, medical or agriculture etc., In this chapter we will study about machine learning and its types with the most common algorithms of machine learning which are being mostly used in different scenarios and their implementation using python language has been discussed in the implementation part of this book. Here we will also see where machine learning can be used.

i. Introduction

Machine learning is a subset of Artificial Intelligence and one of the most important part of artificial Intelligence. It is a field of Computer science which is totally differs from traditional computational approaches. In traditional approaches, a set of instruction is explicitly provided to the algorithm to solve any problem. Whereas in Machine Learning is a domain of an AI which uses a statistical analysis and can enables a system to always learn from its data without any external inputs in order to give an essential output. Due to this machine learning makes computers in advance to make model which provide decision based on input data.

Machine Learning involves a lot of algorithms which usually based on their requirements and functionalities to use where and when. To make a machine learning model we always require the data on which model can be made. Machine learning uses the algorithm which continuously learns from the data available as training data. A machine learning model is generated after the training of algorithm from the data. After the training completes, when trained model is provided with other real-life data then you can get an essential outcome. For example, in figure 3.1 Machine learning Model we use a predictive algorithm and make a model by providing it with some data, and later on we can receive prediction’s based on real data as input.

Deep learning emerged as a serious contender in the field from a 10-year explosive computational development. Deep learning is therefore a special form of machine learning, the algorithms of which are based on the structure and function of the human brain.

Machine learning VS Deep learning

Deep learning is arguably the most efficient form of machine learning. This is so important because they know the best way to solve the problem and how to fix everything. The following is a description of deep learning and machine Learning:

Introduction

Agriculture has played an important role in the global economy in recent years. The further growth of the population is leading to a gradual decrease in the area of the agricultural land and further growing stresses on the farm system. Agricultural food production methods are rising in demand for successful and healthy. Innovative sensoring and motive technologies and advanced information and communications systems and Artificial Intelligence must supplement conventional agricultural management methods to speed up farm productivity growth more accurately, thereby promoting the production of high-quality and high-performance agriculture. Computer vision monitoring systems have become valuable tools in farm operations over the past decades, and their use has increased significantly.

What is Computer Vision?

Computer vision can be characterized as a field of AI for extracting information from digital images. The type of data obtained from an image may be different from recognition, navigational space measurements or applications of increased reality.

The applications of computer vision can also be described. Computer vision builds algorithms that recognize and use the quality of pictures for other purposes.

In this chapter we will look at the Expert system which can guide and assist an individual once it is provided with the enough Knowledge to do so. Here we will discuss about expert system and its architecture with proper steps of making an expert system in any field by several tools which are available to do so. For expert systems the most important is Knowledge Engineering which is the collection of Knowledge from an expert and Engineering it in such a form that a machine could understand it.

Introduction

One of the pioneering fields of AI study is Expert Systems (ES). It is proposed by researchers in the computer science department of Stanford University. An expert system is a computer system which emulates a human expert’s decision-making skills. Expert systems are developed by reasoning through information structures, representing laws, rather than through traditional procedural code, in order to overcome complex problems.

Expert Programs use professional expertise systematically to address human expert problems. An expert is an individual with experience in a specific field. The expert has expertise or special credentials which most people do not learn or care about. An expert can solve or solve problems more effectively than people can solve. Expert System actually emulates all these qualities of expert and solve the problem in a better way and fast.

Today, Expert System (ES) is used in the fields of finance, research, engineering, technology, medicine and many others where there is a well-defined problem area. The fundamental principle is that an expert method should also define the steps to illustrate why a problem can be solved. Unless an individual can justify his reasoning for Expert System.

In this chapter we will talk about the tools which are required to make project in artificial intelligence. All this bellow discussed tools are uses python programming language for making any project in any respective field. We have discussed about how anyone can install and use the tools to built a real time project in artificial Intelligence.

Using Python IDE

To download and install Python visit the official website of Python https://www.python.org/downloads/and choose your version. We have chosen Python version as per requirement all the codes in this book were on python version 3.6 as you can see in the Fig. 7.1.

In this chapter we will cover all the basics libraries and some frameworks of machine learning, deep learning and computer vision. We will discuss all about their use with an example and instruction which will states the commands to install to those libraries for building any project in our system. So let’s begin

What is a Library?

Library is an aggregate of features and methods that allow you to take many actions without getting your own code written.

For instance, the libraries that you have to know are if you work with data, numpy, scipy, pandas, etc. They have very simple data processing functions that save you time for small tricks.

In this chapter of machine learning algorithms we will cover the basic algorithms of machine learning with their implementation using dataset and discuss their pro’s and cons of algorithms for better understanding and how to use them in any project or with any dataset to get an correct result which can useful for research or study.

Key Component

We defined a data set composed of audio, images and binary labels that provided an understanding of how we could train a model from snippets to classifications. This sort of problem is one of many kinds of machine learning problems when we try and predict a specified unknown label given known inputs, provided that a dataset of examples for which labels are known is called supervised learning. Let’s discus what are the major key components we have to get there

Introduction

In agriculture, plant diseases have always been a major problem, as they cause crop quality to decrease, resulting in yield. Plant disease has a range of effects from minor symptoms to serious damages in whole crop areas, which lead to high financial costs and significantly impact the agricultural economy, particularly in developing countries dependent on a single crop or on a few crops.

Various approaches have been developed to detect disease in order to avoid significant losses. Causal agents have been precisely defined by methods developed in molecular biology and immunology. However, for many farmers these techniques are inaccessible and require detailed knowledge of the field or substantial time and energy to be used. According to the United Nations Food and Agriculture Organization, most farms in the world are small and family-owned in developed countries. Such families provide food for a significant proportion of the population of the planet. However, hunger and food insecurity are not rare and there is restricted access to markets and services. For the above reasons, a great deal of work has been undertaken in order to establish methods that are sufficiently reliable and available to most farmers. Where Plant disease is an essential factor contributing to a major decline in plant production quality and quantity. Plant disease identification and classification are a significant role in improving plant production and economic development.

Introduction

The conventional approach of the human person for plant classification is comparing the color and shape of the leaves, but by using Artificial Intelligence analysis can provide quicker and more detailed results by analyzing the morphology of the leaves and provides more details about the leaf properties. Species Recognition has been a very important part of agriculture and there are thousands of species in plants which can be identified by a single person and even if it does so It will take a huge lot of time to do it.

In this chapter we will discuss and built a project related to identify species in flower with an image. In this project we will be using Artificial Intelligence different branches like machine learning, deep learning and computer vision to build such an amazing project. So, let’s begin

In this Chapter the precision farming/ Agriculture is discussed along with its steps of implementation. It also includes how artificial Intelligence plays role to perform precision farming/ agriculture in various way along with its scope, limitation and challenges.

Introduction

The primary source of livelihood is agriculture in India, where two thirds of India’s population, services and the private sector account for the remainder. Agricultural land accounts for about 43 percent of the geographical area of India. In earlier days, India was largely dependent in terms of food imports, but over the years, the country’s production of grain and seeds was self-sufficient, and this effort led to the formation of the Green Revolution. In fact, there was strong effort to achieve food self-sufficiency. This trend has continued up to now and continuous improvements have occurred. Precision agriculture or precision farming means the right thing to do, in the right way, on the right place and at the right time. Precision agriculture is expected to suit the agro-climate activities to improve application precision. Farming land has declined a bit in the last 40 years but the number of farmers has increased. According to the 2010–11 Agriculture Census, a total of 138.35 million operating holdings were estimated (single farmers) and 159,59 million hectares were covered by operations.

Precision agriculture is a management technique that collects, processes and analyzes temporary, spatial and individual data and integrates this with other information in order to support management decisions based on an estimated variability to enhance efficiency of use of agricultural production resources, productivity, quality, profitability and sustainability. Precision Agriculture manages every input of crop production (fertilizer, specifically found calestone, herbicide, seeds, insecticide, etc. Reduce waste, boost income and maintain efficiency Place. Precision Agriculture adapts soil and crop management carefully to suit the different field conditions.
