Biofertilizers

Definition: Biofertilizers are defined as preparations containing living cells or latent cells of efficient strains of micro–organisms that help crop plant’s uptake of nutrient by their interaction in the rhizosphere when applied through seed or soil. They accelerate certain microbial process in the soil which augments the extent of availability of nutrient in a form easily assimilated by plants.

Types of biofertilizers

There are some types of biofertilizers:

1. Nitrogen fixing biofertilizers
2. Phosphorus solubilizing biofertilizers
3. Phosphorus mobilizing biuofertilizers
4. Biofertilizers for micro–nutrients
5. Plant growth promoting rhizobacteria

Mulching

Definition: It is the practice of covering the soil with loose extraneous matter is known as mulching.

Types of mulching

There are two types of mulching:

1. Organic mulching
2. In–organic mulching
3. Organic mulching: In this mulching the open soil is put under loose cover of straw, hay, crop residue, leaves, saw dust etc.
4. In–organic mulching: In this mulching the open soil is put under plastic, film, metal foil, sand, stone etc.

Plant growth

Definition: The quantitative increase in plant body such as increase in the length of stem and root, the number of leaves etc., is referred to as plant growth.

Plant development

Definition: The qualitative changes such as germination of seed, formation of leaves, flowers and fruits, falling of leaves and fruits is referred as developement.

Phytohormones

Definition: These are the organic substance or hormones produced by plants which in low concentrations regulate plant physiological process. It is synthesized in one part of plant and translocated to other parts. These are endogenous substance means naturally occurring in the plant.

Weed

Definition: “Weed is an unwanted plant growing where it is not desired.” – Jethro Tull

Commonly noticed weed species in fruit orchard:

• There are more than 30,000 species of weeds distributed world over, out of which 18,000 are noxious and cause serious losses.
• Around 250 species are causing serious economic losses.
• Monocot weeds (Narrow leaf/Grasses): Cyprus, Cynodon, Poagrass, Rye grass, Quackgrass etc.
• Dicot weeds (Broad leaf weeds): Dandelion, Chenopodium spp., Parthenium, Solanum, Euphrobia spp., Ground ivy etc

Water

• Water constitutes about 35–95% of the different portion of the plants. The leaves of the plant contain 35–95% water, Roots 60–90% and Fleshy fruit contain 70–90% water.
• Water is one of the most important inputs essential for the production of crops.
• Plants need it continuously during their life and in huge quantities.
• It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients etc.
• Soil needs the application of water to:
• Remove stress condition.
• Release nutrients in the soil solution for absorption by plants.
• Preparation of land for raising crops.
• To maintain the temperature and humidity of the soil micro–climate and the activity of soil microbes at optimum level.

Soil fertility

• Soil serves as a source of nutrient required for the growth and development of plant. This characteristic of soil is called soil fertility.

Management practices

• Improved organic matter and soil moisture in soil, favours the growth of micro-organism beneficial for maintaining fertility of the soil.

Manures

• It is an organic waste material of plant and animal origin. It is used improvement of soil fertility. There are major 2 types of manure

1. Bulky organic manures
2. Concentrated organic manures

Nutrient

Definition: Those elements are required for plant metabolism in more or less quantity, is known as nutrients. Plants have 30 types of elements but 17 elements out of 30 are essential for plant growth and development. These elements are called Essential nutrients.

Criteria of essentiality of plant nutrients theory: It is given by Arnon and Stout (1939). This theory stated that plant can not be completed their life cycle without the deficiency or complete absence of a single nutrient among the essential nutrients

Low of minimum: It is given by Justus Von Leibing (1840). According to this low, the growth of the plants is limited by the plant ntruient present in smaller quantity, all other being in adequate amounts. This has been re–stated as Barrel concept.

Allen and Arnon (1955) laid out following criteria for categorising nutrients essentiality to plants:

1. Complete or partial lack of the element in question must make normal plant growth impossible
2. Deficiency symptoms must be reversibly by the addition of the elements in question
3. The element must play specific role in the plant metabolic symptom

Propagation

Definition: Multiplication of plant is termed as propagation.

Types of propagation

There are mainly two types of propagation

1. Sexual propagation
2. Asexual propagation

Training

• Training is related to shape and size of the plant.
• In this process, removal of part of the plant to develop a proper shape.
• It develops strong frame work of tree, balance between vegetative and reproductive growth and facilitate interception of sunrays to each and every part of trees.

Methods of training

Central leader system

• Main stem of tree is allowed to grow continuously.
• First branch is allowed to grow 45–50 cm height from ground level and other branches are allowed to grow on main stem at a distance of 15–20 cm.
• The tree attained Robust shape
• It is not suitable for high altitude and hot arid areas.

Planning

• Generally 10% of the total area is left aside for building, roads, paths, tube-well, channels etc.
• Windbreak is very important aspect of orchard planning.
• Windbreak plants are planted in North–Wset direction.
• The market should be vicinity of orcharding site. It reduces transportation.
• The site of orchard should not be a wind or flood prone area.
• The soil should be neutral in reaction (pH 7).
• As per climate adaptability, fruit plants have been classified into three groups; tropical, sub–tropical and temperate types.

Greenhouse

It is constructed by plastic, polythene, and fibreglass material having temperature control and ample light availability needed for propagating plants by seed, cutting and grafting.

Types of greenhouse

1. Based on shape and style: The commonly followed types of greenhouse based on shape are lean–to, even span, uneven span, ridge and furrow, saw tooth and quonset greenhouse.

Lean–to type greenhouse:

• It is limited to single or double–row plant benches with a total width of 7–12 feet.
• It is typically facing south side. It should face the best direction for adequate sun exposure.
• This design makes the best use of sunlight and minimizes the requirement of roof supports.
  • It has the disadvantages: limited space, limited light, limited ventilation and temperature control.

Nursery

Definition: It is a small area or place where seeds are sown for getting baby plant to transplant in the main field. These baby plants are known as seedlings.

Generally, growing rootstock in fruit plants and small seeded vegetables like tomato, brinjal, onion, cole–crops etc are needed to raising nursery and further transplanting.

There are two types of nursery;

• Temporary nursery: This nursery is raised by soil in open condition.
• Permanent nursery: This nursery is raised permanently walled and often provided with overhead covering against rain or frost.

Bearing: Bearing is connotation of flowering and fruiting.

Bearing habit: The position of f lower bud with respect to vegetative growth of the plant after the cessation of juvenility. Different fruit plants have different habits.

Depending upon position of fruit bud, fruit trees may be categorized as under:

1. Shoot flowering: Terminal flowering: Banana, Pineapple, Mango, Litchi, Avocado Lateral flowering: Coconut, Papaya, Guava, Orange, Ber, Passion fruit, Bread fruit
2. Stem /Branch bearing: It also known as caulifluorous bearing habit. In this habit, flower and fruit appear directly from the main stem or branch. Example: Jackfruit, Cocoa, Durian,
3. Spur bearing: It is a shot stubby shoot of more than one year age which bears fruit bud in many fruit plants. Example: Apple, Pear, Peach, Plum, Cherry, Grape, Apricot etc

I. Classification of fruit crops

1. Based on botanical relationship

• It is the technology of intensive production system.
• In which modern, less environmental dependent and capital–intensive but with a capacity to improve productivity and farmer income.
• Use of plastics, protected cultivation, precision farming, high density planting (HDP), integrated nutrient management (INM), integrated pest management (IPM), mechanization etc., are important facets of hi-tech horticulture. There are many practices which helps to enhance horticulture production:

The Indian subcontinent is bestowed with a great variety of climate and soil conditions.

• Broadly the country can be divided into Tropical, subtropical and temperate regions.
• Within each broad category there are differences due to rainfall, humidity, altitude etc.
• Considering these aspects six different horticultural zones have been identified so that appropriate choice of the crops can be made and development is planned. They are;
• Temperate: Kashmir, Himachal Pradesh, North Uttarakhand, Sikkim and part of Arunachal Pradesh.
• N.W. Subtropical: Punjab, Haryana, Rajasthan, Central Uttar Pradesh and North M.P.
• N.E. Subtropical: Bihar, Jharkhand, Assam, Meghalaya, Nagaland, Manipur.
• Central tropical: South Madhya Pradesh, Chattisgarh, Gujarat, Maharashtra, Orissa and West Bengal.
• Southern tropical: Karnataka, Andhra Pradesh and Tamil Nadu.
• Coastal tropical humid: Konkan, Goa, Kerala, Western Ghats, Eastern Ghats in Tamil Nadu, Andhra Pradesh and Orissa.

The Total Horticulture production of the country is estimated to be an impressive level of 314.87 Million Tonnes during 2018–19.

Production of fruits is estimated to be about 97.38 million tonnes during 2018–2019.

Production of vegetables is estimated to be about 187.36 million tonnes during 2018–2019.

Production of spices is estimated to be about 8.61 million tonnes during 2018–2019.

Plantation crops are another potential sector with lot of opportunities for employment generation, foreign exchange earnings and overall supporting livelihood sustenance of mankind at large.

In short and sweet horticulture supplies quality food for health and mind, more calories per unit area, develops better resources and yields higher returns per unit area.

It also enhances land value and creates better purchasing power for those who are engaged in this industry. Therefore, horticulture is important for health, wealth, hygiene and happiness.

Similar to forest trees these horticultural trees will maintain the ecosphere. They help in transforming the micro climate.

It provides shelter to birds, reptiles and other micro organisms and add to the geo–ecological diversity on the land.

1. INTRODUCTION

Vegetables play a significant role in human nutrition, especially as sources of vitamins, minerals, dietary fibre and antioxidants. Consumption of vegetables on a daily basis is highly recommended because of its associated health benefits, which include reduced risk of chronic diseases.

Due to perishable nature of vegetables, the post harvest losses of these commodities are four to five times higher than those of food grains. The post harvest losses from vegetables accounts to a tune of Rs. 23,000 crores per year. Both quantitative and qualitative losses occur in horticultural commodities between harvest and consumption. Qualitative losses, such as palatability, nutritional quality, caloric value and consumer acceptability of fresh produce, are much more difficult to assess than the quantitative losses.

Postharvest losses vary greatly across commodity types, with area and the season of production. In contrast, the range of produce losses in developing countries varies widely. Losses at the retail, food service and consumer levels are estimated at approximately 20 per cent in developed countries and about 10 per cent in developing countries. Overall, about one third of horticultural crops produced are never consumed by humans. Reduction of post-harvest losses can increase food availability to the growing world population, decrease the area needed for production and conserve the natural resources.

1. INTRODUCTION

The past hundred and fifty years of this millennium have witnessed an unbelievable pace of scientific and technological development. Modern science has attempted to a great extent and succeeded in realizing the dreams and fantasies of philosophers and scientists of the previous centuries. Plant genetic engineering via., nucleus is a mature technology that has been used productively for research and commercial applications. However, plants have an unassuming second genome inside the tiny organelles called as plastids. Although this small circular DNA carries a fewer genes than its nuclear counterpart, researchers say its potential for genetic engineering far outstrips its size. The ability to introduce foreign genes at specific locations on a chloroplast has been acquired very recently. It is expected that certain limitations of nuclear genome transformation methods in terms of protein expression and environmental safety can be overcome by site-specific introduction of genes into plastids. Thus the plastid engineering forms a viable alternative serving as another milestone in the field of plant biotechnology.

1. INTRODUCTION

The Technology Protection System (TPS) or “Terminator Technology” as it has been called, allows plant breeders to genetically modify and protect their crop rights so they produce seed for one generation only. TPS was co-developed by the US Department of Agriculture (USDA) and Delta and Pine Land Company in 1998. They received U.S. Patent 5723765 entitled “Control of Plant Gene Expression”. The patent was based on research conducted under a Cooperative Research and Development Agreement (CRADA) between Delta and Pine Land Co. and the ARS USDA. The CRADA was signed in 1993.

1. INTRODUCTION

Plants produce an array of natural products, the secondary metabolites, which play a variety of roles such as pollinator attractants e.g. pigments and scents and defense molecules against attacks by animals and microorganisms. These substances are very much important as a source of pharmaceuticals, fragrances, agrochemicals and food additives. Great efforts have been made by the chemical industry to mimic and synthesise these compounds. However little success has been achieved and plants still remain the major source of these vital compounds (Wink, 1990). In the late 1970s plant cell culture was thought to be an alternative or additional way of producing these compounds (Alfermann and Peterson, 1995). The low yields obtained with cultured cells and inferior to the amounts present in intact plants, provided a major drawback to their commercial exploitation. The plant derived pharmaceuticals represent a large market value; about 25% of today’s pharmaceuticals contain at least one active ingredient of plant origin. So only a minute fraction of the enormous biosynthetic potential of plant cells is being exploited. The most popular analgesic drug aspirin and the most valuable anti-cancer drugs paclitaxel and vinblastine are derived solely from plant sources (Pezzuto, 1996).

Over the last 10-15 years, the successful genetic transformation of plants has been reported in about 200 species including agricultural crops, trees, ornamentals, fruits and vegetables. Such genetic modification has improved specific crop traits, such as resistance to pathogens, to herbicides and to various environmental factors including drought and floods (Bajaj and Ishimaru, 1999). Following on from this success genetic transformation of medicinal plants has been attempted, primarily to enhance the production of various pharmaceuticals, flavours and pigments. During the early 90’s it was suggested that metabolic engineering of biosynthetic networks might be achieved by application of recombinant DNA methods.

1. INTRODUCTION

Plant diseases are major constraints to plant growth and development (from seed to maturity) resulting in crop losses. Plants are exposed to attack, by a wide variety of microbes like bacteria, virus, fungi, phytoplasma and as an abnormality they cause disease. To counter these threats, plants have evolved a series of defense systems in response to the pathogen challenge inhibiting natural resistance. Thus disease is an exception rather than rule. However on failure of the inbuilt resistance mechanism, outbreak of disease has led to the widespread use of chemicals that have deleterious environmental and human health consequences. To enable the development of more effective and durable resistance against pathogens, a detailed analysis is necessary to identify the genes and mechanisms involved in plant defense/resistance.

Recombinant DNA and gene transformation technologies have potential to augment traditional breeding efforts (limited by genetic variability) by circumventing taxonomic limitations to gene pool for pathogen resistance. Further manipulation of defense genes in transgenic plants provide novel approaches for engineering pathogen resistance. It becomes important to understand the different components of plant defense to exploit host plants for resistance Thus the review is focused on plant genes and proteins that are known to play a major role in plant resistant against pathogens.

1. INTRODUCTION

Micropropagation is a specific aspect of plant tissue culture dealing with the aseptic vegetative multiplication of plants in-vitro and is divided into several major stages:

Stage 0: Stock plant selection and preparation

Stage 1: Initiation and establishment of an aseptic culture

Stage 2: Multiplication

Stage 3: In-vitro rooting and conditioning

Stage 4: Acclimatization to ex-vitro environment. (Hartmann et al., 1990)

1. INTRODUCTION

The terms antioxidants and free radicals are being very effective used nutritionists and other health professionals. Antioxidants are compounds are good for health and free radicals are harmful. In general, antioxidants neutralize free radicals that are generated in the body and prevent damage to cell proteins, lipids and carbohydrates. Antioxidants can be water-soluble or lipid-soluble, thus they exist within the lipid or within the water portion of cells. Antioxidants are substances when present in food or in body at low concentration retards or prevents undesirable oxidation of substrates by free radicals.

Within the human body, millions of processes are occurring at all times. All cells require oxygen to generate energy; higher eukaryotic organisms cannot exist without oxygen. Unfortunately, that same life giving oxygen can create harmful side effects which cause cell damage and lead to chronic disease. Damage caused by free radicals is called oxidation. Oxidative stress is the disturbance in the prooxidant-antioxidant balance in favour of the former, leading to the potential damage.

1. INTRODUCTION

Many food components are encapsulated and stabilized by nature inside plant cells, but, with the growth in use of functional ingredients and product fortification with vitamins, antioxidants and nature-identical synthetic compounds, there is a need to stabilize and protect these ingredients from the rigours of processing and degradation during storage.

Many food products whose development was thought to be technically unfeasible are possible today because of the wide availability of encapsulated ingredients. Such ingredients are products of a process that totally envelops the ingredient in a coating or ‘capsule’ thereby conferring many useful and otherwise unusual properties to the original ingredients.

Encapsulation is a technique that is applied to preserve and/or protect numerous ingredients. In the flavour industry, the encapsulation process is used chiefly to convert liquid flavour materials to free-flowing, dried powdered products. In a broad sense, encapsulation technology includes the coating of minute particles of ingredients (e.g., acidulants, fats, and flavours) as well as whole ingredients (raisins, nuts, and confectionery products) that may be accomplished by microencapsulation and macro-coating techniques, respectively.

1. INTRODUCTION

The numbers of plant products that influence the nervous system are many and particular group that act on central nervous system by influencing neurotransmitters or endorphins are treated as psychoactive plants. Psychoactive drugs that act on the central nervous system are very much involved in psychiatry. The range of effect is wide for these plants and they can be divided into three categories viz.,

• Stimulants, which excite and enhance psycho motor activity.
• Depressants which reduce mental and physical performance and
• Hallucinogens which are capable of inducing dream like state.

A wide range of plant derivatives are involved in these mind altering drugs.

1. INTRODUCTION

Organic farming systems can deliver agronomic and environmental benefits both through the structural changes and the tactical daily management of the farming system. The benefits of organic farming systems are relevant both to developing and developed nations which helps for environmental protection, biodiversity enhancement, reduced energy use and CO₂ emissions (Thiyagarajan, et al., 2003). The post Green Revolution era has led to environmental pollution due to excessive use of agrochemicals and fertilizers and thus threatened the fragile ecosystem (Selvaraj et al., 2001). Organic farming conserves soil fertility and curtails soil erosion through implementation of appropriate conservation principles (Thampan, 1995). Organic farming leads to live in harmony with nature.

United Nation experts indicate that organic foods have the good opportunities for developing countries to open a space in the global market. This entails the creation of greater awareness of trade opportunities for organic products as well as of the environmental, economic and social benefits to the public.

1. INTRODUCTION

India is traditionally rich on agricultural knowledge. Presently modern farming is not sustainable in consonance with economics, ecology, equity, energy and socio–cultural dimensions. Indiscriminate use of chemical fertilizers, herbicides and pesticides to boost the yields have resulted in various environmental and health hazards along with socio–economic problems. The agricultural production has continued to increase, but the trend in productivity has started declining. The agricultural scientist’s and farming community whole heartedly aim at an alternative sustainable farming system which will be ecologically sound, economically viable and socially acceptable. The answer to the problem lies in refining our own traditional practices based on natural and organic farming methods offering several safe, feasible and cost effective solutions.

The term ‘Organic farming’, a system of farming is one which avoids synthetic fertilizers but rely upon crop rotation also using crop residues, animal manures, legumes, green manures, biofertilizers, organic wastes etc., to maintain the soil fertility and increase productivity. This system enables the nutrients leaching from perennial wood and vegetation and help to maintain organic matter and protect the soil from surface erosion. The world wide awareness for adopting organic farming has paved way for streamlining the production technology and certification by adopting the specified crop production practices. Organic farming practices in agriculture and animal husbandry are native to East Asian countries, like India and China. In China a strong national movement for animal waste recycling is in vogue, minimizing the use of inorganic fertilizers (Xu, 2000), while in our country specific crop production practices are developed in isolation and adopted locally.

The trend of use of chemicals and industrial inputs in intensive farming is increasing which resulted in soil health deterioration and increased environmental pollution which causes a great concern all over the world. Therefore an emphasis on the need to use the organics and other byproducts of agriculture and industry is emerging. Fortunately, the country is already rich with left over crop residues (185 million tonnes) but its use presently is limited. Apart from crop residues, there is an enormous quantity of cattle wastes out of which sixty per cent of the used for fuel purpose in rural areas.

1. INTRODUCTION

‘Fertigation’ is the technique of supplying dissolved fertilizer to crops through an irrigation system (Haynes, 1985). When efficient irrigation system combined with both nutrients and water, it can lead to obtain higher yield and preferable quality desired marketable produce.

Often, side-dressings of straight solid fertilizers are found to be the management constraints. Most of the growers have the experience of how much the applied fertilizer is either washed from the soil in run-off or leached below the root zone.

Continuous small applications of soluble nutrients have the benefits like labour, due to fertilizer being placed uniformly around the plant roots and allow savings/economy rapid uptake of nutrients by the plant.

1. INTRODUCTION

The basic principle of plant breeding is the utilization of existing variation and creation of new variations. Ploidy breeding is one of the tools used for improving the crop plants. The year 1937 can be considered as a landmark in the history of plant breeding. The discovery of the specific action of colchicine in inducing polyploidy has provided the breeder with a means for increasing the scope of crop improvement apart from the removal of the barrier of sterility in the sterile interspecific hybrids by the production of amphidiploids and their utilization later for the transfer of useful genes from the wild parents to cultivated plants. It was hoped that the production of autoploids in various crop plants would directly lead to the cultivation of better plants, as generally the autopolyploids are known for their gigas characters including the seed.

1. INTRODUCTION

Today’s technological advancement have reached a level where a farmer can have access to information and tools to manage his mechanized field operations. They can now measure, evaluate and deal variability with infield (e.g. soil fertility, water availability and yield) that was known to exist previously but was not manageable, to his advantage. The ability to handle variations in productivity within a field and maximize financial return, reduce waste and minimize impact on the environment has always been the objective of an enterprising farmer, especially those with limited land resources and those who advocate sound agriculture practice.

This concept is not new. What is new is the ability to automate data collection and documentation and the utilisation of this information for strategic farm management decision in the field operations through mechanisation, sensing and communication technology. Such an approach in agriculture production management gives rise to what is now termed as Precision Farming (PF), Precision Agriculture (PA), Prescription Farming (Precision farming), Site Specific Agriculture (SSA), Soil Specific Crop Management (SSCM), Spatially Variable Crop Production (SVCP) etc.

Goat is the 1st domesticated animal in the ancient age and has been considered to be the Poor Man’s Cow Goat’s meat is lean & has low fat and the demand for goat’s meat is increasing, with rising prices. Goats usually give birth to twins & triplets. Goat is a multi functional animal and plays a significant role in the economy and nutrition of landless, small and marginal farmers in the country. Goat rearing is an enterprise which has been practiced by a large section of population in rural areas. It can efficiently survive on available shrubs and trees in adverse harsh environment in low fertility lands where no other crop can be grown. In pastoral and agricultural subsistence societies in India, goats are kept as a source of additional income for their meat, hair fiber, and dairy, or as a pet. Goats are also used in ceremonial feastings and for the payment of social dues. According to FAO (2008) goat milk production in India were 4 million metric tons, Bangladesh 2.16 million metric tons and the Sudan 1.47 million metric tons over much of the world. Goats are among the main meat-producing animals in India, whose meat (chevon) is one of the choicest meats and has huge domestic demand (Shalander Kumar, 2007). Goat rearing is an enterprise which has been practiced by a large section of population in rural areas. Goats can efficiently survive on available shrubs and trees in adverse harsh environment in low fertility lands where no other crop can be grown. (Oberoi et al., 199I) reported that in variable cost, expenditure on labour was the major component of cost and was 81% under goat farming.

Introduction

Three hundred million poor people in Asia depend on livestock for their livelihoods and there are opportunities for improvement in livestock related livelihoods due to the rapid and dynamic changes that the livestock sector in Asia is undergoing (Njuki et al. 2010). Piggery farming has been recognized as one of the profitable venture among the rural masses. This venture has proved to be one of the most important livelihood option. Generally the pigs are reared for pork, considering the increasing trend of pork consumers in India; Piggery farming will certainly take a industrial form of livelihood in India in future. There are more than 12.8 million pigs in our country, out of which approximately 14.5% are graded and of exotic variety. There are 120 pig breeding farms in the country whereas pigs of exotic breeds are maintained. China ranks first in the world in pig rearing where number is around 300 million or 1/3 of the world pig population.Pig production is basically an enterprise which is able to convert inedible or inferior quality food into the food rich in animal protein. Pig is considered a machine because they convert grain, pasture and other low quality feed into Pork which is used as human food (Rahman, 2008) . Despite the fact that pig rearing is a profitable enterprise most of the progressive farmers even today hesitate to adopt it due to prejudice sentiments in our society against pig farming. For many others there is religious taboo against pig. A majority of meat eaters also and cheap source of protein. Pork as a source of animal protein is gaining popularity in India and pork products will be in greater demands in years to come. The high carcass yield attracts the farmers because of the better returns within the shortest possible time. High fertility in pigs assumes income to the rearer round the year. To bring about improvement in the productivity of pork and other piggery products extensive crossbreeding programme has been taken up to develop animals of large size, better feed conversion efficiency, high dressing percentage and better quality pork. Pig keeping also contributes to socio-cultural obligations and risk diversification and converts existing resources and low value waste products into high-value animal source food for home consumption and/or sale (NEPED, 2008).

Lac insect is an insect of commercial importance like silk worm and honey bee. The silkworm produces silk, honeybee produces honey and wax whereas, lac insect produces three products namely resin, dye and wax of great commercial importance. The resin commonly called lac, is only one of animal origin and commercially available in the market as shellac or seed lac or as a button lac. The resin is in fact the hardened secretory product of lac insect secreted as a protective covering of an insect. Lac culture is one of the important sources of livelihood and rural economy for poor resource constraint people particularly inhabiting in forest and sub-forest areas. It is one of the important sources of livelihood security in many parts of the country in states like Jharkhand, Chhattisgarh, Madhya Pradesh, West Bengal, Odisha, Maharashtra, Madhya Pradesh, Uttar Pradesh, Assam, NE regions etc (Pal et al., 2007). It has also high potential for generating employment for both men and women in forest and sub-forest areas of the country. It is a very remunerative crop, paying high economic returns to the farmers and also foreign exchange for the country through its export.

India is endowed with 8118 kilometers of coastline and access to 5.3 lakh square kilometers of continental shelf to facilitate marine fishing.195210 kilometers long river and canal system, more than 6 million hectares of water bodies under reservoirs, ponds, Fish is an integral part of food and culture in India. Indian coastal region is rich in aquatic bio diversity with various identified fish species and also in aquatic resources. India with its vast and varied marine and inland resources stands third in world total fish production and second in inland fish production. India’s fish production has increased from 5.6 million tonne during 2000-2001 to 6.9 million tonne during 2006-2007. During the year 2006-07, the country witnessed foreign exchange of Rs.8363.53 crore through export of sea food. Fish processing industries in India are gaining importance in recent years due to increase in demand of processed food by the developed countries. In India fishery sector provide livelihood to an estimated 10 million people and the Inland fisheries are of particular importance to the rural poor accounting for about 15% of total global employment (FAO, 2000). Sustainable utilization of available resources with appropriate farming system approaches will increase fish production and also will generate employment opportunities.

Amongst agricultural commodities milk is the single largest contributor to gross value of output followed by paddy, wheat, oilseeds, pulse and sugar. It is not only that, milk is also least contributor to inflation.Thus it can be said that milk is the lifeline of Indian economy. Unlike developed countries, unique feature of Indian milk production system is that about 70% of it is produced in about 70 million household dairy units in rural areas.Dairy farming has always been a subsystem of agriculture in such household units which entirely depends on the recyclable crop residues. Moreover the milk production system has been mainly confined to landless labourers, small and marginal farmers.Their poor socioeconomic condition, religious sentiments for cattle and utilitarian attitude towards dairy farming coupled with poor milk production potential of dairy animals has remained a major impediment in the overall development of the system. Livestock is an important source of supplementary income. Mixed farming has been serving as an insurance against natural calamities, while supporting food security and nutrient recycling. India has over 500 million livestock, which include cattle, buffaloes, sheep and goats. Among them, cattle and buffaloes are popular for milk production. As milk is an important part of the Indian diet and bullock power is essential as draft animal for farming and rural transportation.

India is emerging as a global economic power and the economy is growing at an average of 8 9 per cent for last couple of years.The Dairy sector is contributing significantly to the national economy and with 112 Million Metric Tonns (MMT) milk productions during 200910; it ranks first in the World. It provides gainful employment and supplementary income to large number of people. Dairy sector contribute significantly on poverty reduction in rural areas as income from milk in the total income of underprivileged family is as high as 75 to 80% during drought and the employment generated is relatively high. Dairying has become an important secondary source of income for millions of rural families and has assumed an important role in providing employment and income generating opportunities.

Mechanization is viewed as package of technology to increase land productivity by improved timeliness of operations, reduced crop losses and improved quality of agro-produce to increase efficiency of inputs used through their efficient measurement and placement, to increase labour productivity by using labour saving and drudgery reducing devices and reduce cost of cultivation. echnology and machinery enhanced the ability, quality, accuracy and efficiency of the human being. By using technology in any field the rate production and quality automatically increases. The country witnessed unprecedented growth in agriculture which has helped India to graduate from hunger to self sufficiency in food grains by increasing the food grain production from 51 million tonnes to 208 million tones. The estimated contributions of improved agricultural tools and equipment in augmenting total food production of India is encouraging; savings in seeds: 15-20%; savings in fertilizers: 15-20%; savings in time: 20-30%; reduction in labour: 20-30%; increase in cropping intensity: 5-20%, and increase in productivity 10-15 per cent. The major issues before Indian agriculture with respect to mechanization are; tractorization vs mechanization, custom hiring and contract farming, horticultural mechanization, effective extension activity, sugarcane mechanization, hill agriculture and industry institution interaction. The main technologies which can be taken to farmers’ field for enhancing productivity and production Aqua-ferti seed drill, two row powered seeder, okra planter, tractor mounted inclined plate planter, tractor mounted rotary tiller (Rotavator), tractor mounted zero-till drill, tractor mounted raised bed planter, tractor mounted sett cutter planter for sugarcane, pneumatic planter, vegetable transplanter, low land manual rice seeder, self-propelled rice transplanted, self-propelled power weeder, tractor operated aero blast sprayer, tractor mounted vertical conveyor reaper, maize dehusker-cum-sheller, tractor operated straw reaper (combine) and tractor operated fodder harvester. These technologies need to be introduced after necessary modifications and adjustments, depending upon the agroclimatic and terrain and soil conditions, through proper mode e.g. as individual /group ownership, on custom hiring basis or mechanization package for contract farming.

Mushrooms are fleshy fungi constituting a purely vegetarian diet, which is very tasty and nutritious. Some mushrooms are edible whereas others are poisonous. So far, more than 1600 types of mushrooms are known of which, nearly 100 have been accepted as food worldwide. Diversification in any farming system imparts sustainability. Mushrooms are one such component that not only impart diversification but also help in addressing the problems of quality food, health and environment related issues. One of the major areas that can contribute towards goal of conservation of natural resources as well as increased productivity is recycling of agro-wastes including agro-industrial waste. Utilising these wastes for growing mushrooms can enhance income and impart higher level of sustainability (Manjit Singh et al., 2011).

Mushroom cultivation activities can play an important role in supporting the local economy by contributing to subsistence food security, nutrition, generating additional employment and income through local, regional and national trade; and also offering opportunities for processing enterprises. Among the 33 globally cultivated types of mushrooms 3 mushrooms i.e. white button, oyster and paddy straw mushrooms are popularly grown in India.

Honeybees are marvelous insects known to mankind since the prehistoric times. The art of their scientific management is called as apiculture or beekeeping and the place where hives are maintained is called apiary. Beekeeping is a decentralized, forest and rural agriculture based industry, which does not require any raw material. The raw material needed is in the form of nectar and pollen, which is freely available from flowers in nature. Bee hives neither demand additional land space nor do they compete with agriculture or animal husbandry for any input. The beekeeper only needs to spare a few hours in a week to look after his bee colonies. Beekeeping is therefore ideally suited to him as a part-time occupation. Beekeeping constitutes a source of sustainable income for the rural and tribal farmers. It also provides them valuable nutrition in the form of honey. However, in addition to honey, production of bees wax, propolis, pollen, royal jelly, pedigree queen bees, package bees and renting out honey bee colonies for crop pollination are some of the potential areas of apicultural diversification in India (TOI, 2012).

Most of the horticultural produce is of perishable nature and must be protected from postharvest losses, which start from the field itself. Therefore, adoption of proper packing house operation plays a very crucial role in minimizing postharvest losses

Although, we have reached new heights in the production of fruits comparable to China, Brazil and USA and in vegetables to China, yet we are far behind in postharvest management of these perishables, primarily due to lack of appropriate infrastructure. Test studies conducted in Australia have indicated that the distribution cost of perishable horticultural produce is assumed 5 to 9 times, the production cost. Further, packaging accounted for 25-50% of the wholesale price of fruits and vegetables. In India, huge losses of horticultural produce (25-30%) after harvest are encountered mainly due to non-existence of packing house concept.

Packing house operations essentially begins with the use of proper field containers, field transport, temperature protection of harvest produce, sorting, sizing, grading, packing, which are essential preparatory steps to storage, shipment and subsequent marketing. Depending on the kind of produce, additional activities viz. degreening, curing, washing, ripening, waxing, precooling etc. are done. The sequence of activities varies with the crops. A considerable quantity of postharvest losses of horticultural produce could be minimized by adoption of various packing house operations described below:

Agriculture shapes the foundation of Indian economy and despite the fact that there has been vast industrialization in most 60 years; horticulture still occupies a place of significance. In India, approximately 20-25% of the horticulture produce goes waste due to improper post harvest operations which reduces the growers share in the present marketing arrangements. The grower is getting hardly 25-35 paisa of a consumer rupee. The Value addition activities where the fruits and vegetables are processed, that fetches higher remunerative prices of the produce. Such opportunities are presently not available in rural areas but could be created through selective mechanization of agriculture and appropriate post harvest management and value addition to the harvested biomass in the production catchments.The agricultural produce involves operations like cleaning, grading, drying, storage, milling, packaging, transport, marketing and utilization. At the end of each operation, value is added to the product. The lowest and the highest monetary values of a food commodity are, respectively, when it is in raw and fresh form and when it is in processed and ready to consume/eat form. Post harvest and food processing technology are commodity and location specific. It prevent avoidable post harvest losses and adding value to the fresh agro-produces. It also creates opportunities for employment and income generation. Integration of production agriculture with on-farm primary processing is needed to have higher and sustainable production, productivity and better quality end products for domestic and export markets. It would help in reducing rural- urban disparity and ensuring household food and nutritional security for all at an affordable cost. The technology is available and a wide range of tools, machines and equipment are used in post-production of agriculture. The globalization of trade may compel many agro processing industries to rely on an imported technology at a high cost and the advantage of such technology may be availed by a few who have an exclusive business interest. Majority of agriculture-based enterprises will continue to depend upon indigenous technology and, therefore, R&D through public support has to be strengthened to become globally competitive and serve small-scale food processing sector of the country.

India produce a wide range of tropical, subtropical and temperate horticultural crops at different places by virtue of its varietals agro- climate conditions. The total annual production of fruits and vegetables is around 135.5 million tones, fruits being 48 million tones and vegetables around 87.5 million tones. India is the second largest producer of fruits and vegetable in the world. They are major sources of important valuable vitamins and minerals. Being highly perishable, fruits and vegetables can be preserved and processed either at farm level or at cottage scale/home scale during market glut season or extra seasonal produce from kitchen garden for later use. Farmers and entrepreneurs can set up their own processing units by adopting simple, low cost innovative processing technologies which will save post harvest losses of these perishable crops and also give good returns to grower and better earning to processor/ entrepreneurs.

Cereals and pulses are the staple food in India, thus it has to be stored by producers in their homes and by traders and government agencies. Variations in the season i.e., warm and high humidity weather is highly conducive to proper development and rapid multiplication of storage insect pests. Almost all insect pests of stored grains have a remarkably high rate of multiplication and within one season, they may destroy 9-10% of the grains and contaminate the rest with undesirable odors and flavors. The type of insects infesting grains vary and include weevils, moths and beetles. Apart from this it is necessary to control or kill egg, larval, pupal and adult stages of the insect. After proper cleaning and drying the produce is stored where damage can be caused due to cross-infestation or infestation already left in the produce. Grains are stored in different types of receptacles and to protect it, different protectants are being used since from the early days. The success in the use of these protectants (organic, inorganic or inert) depends upon the effect on the grain, killing of the insects, practicability, period of storage and lastly the physical and chemical state of treated seeds.

1. Inert dusts

Inert dusts are fine powders chemically inactive but cause considerable insecticidal activity by mechanical abrassing and physical absorption of moisture proofing layers of insect integument. The use of inert dust was initiated sometimes during World War II. Some common inert dusts are ashes, clays, gypsum, lime, magnesite, Nakki, silica, talk, phosphates, diatomaceous earth. It was reported that though most of the dust proved effective and convenient to use but it is difficult to remove it and clean as it goes inside the infested and damaged grains. The dust can only kill larvae and adults moving in between the grains. Once any stage of insects entered inside the grain, it is beyond the reach of the dust.

As early as in the 18^th century, the anaerobic process of decomposing organic waste was known. During 19^th century, it became clear that anaerobic bacteria are involved in the decomposition process (DST, 1981). Since that time, the applications of anaerobic digestion have grown steadily, in both its microbiological and chemical aspects. The process of anaerobic digestion possesses a double advantage i.e. the process in addition to providing good quality manure also supplies a large volume of combustible gas. Anaerobic digestion provides some exciting possibilities and solutions to such concerns as alternative energy production, handling of human, animal, municipal and Agro-industrial wastes safely, controlling environmental pollution and expanding food supplies. The technology of anaerobic digestion (Kumar et al., 2015) has not yet realized its full potential for manure and energy production even in developed and industrialized countries. In developing countries expansion of this technology has been hindered because of the need for better economic initiatives, organized supervision, proper training and education.

During twentieth century, the method of anaerobic fermentation or digestion was successfully applied by sewage chemists. A considerable amount of research work was carried out by sewage chemists on different aspects of the digestion process and sludge digestion plant, were installed. The gas produced was used for burning as domestic fuel, operating machinery and for tractors. In this context, the studies on anaerobic digestion of cattle dung and vegetable waste has been important. The work is particularly important ones in the Indian context as long as gas production and plant design efforts are concerned. For research on anaerobic digestion energy part (methane generation) received more attention since the early decades of this century when research into bio digestion had gradually begun to take shape. Fertilizer aspect received occasional attention a couple of decades later. The engineering and micro biological aspects of gas production remain a dominant preoccupation even up to 1990s. Emphasis on the energy aspect still dominates in many parts of the world today.

Indian agriculture, accounting for 25% of the nation’s Gross Domestic Product (GDP), 15% of exports and 60% of the employment continues to be the mainstay of economy. Having achieved laudable success in agricultural production in the last 50 years (50 Million ton to 210 Million ton) India has transformed herself from a food deficit country to a food surplus country. Still there are many challenges, which Indian agriculture is facing, in a fast changing technical and socio-economic scenario. Relating to the natural resources and production base, water has emerged as the most crucial factor for sustaining the agricultural sector. India accounts for 16 percent of the world’s human population and nearly 30% of the cattle with only 2.4% of the land and 4% of the water resources.Even if the full irrigation potential is exploited, about 50% of the country’s cultivated area will still remain unirrigated, particularly with the current level of irrigation efficiency. The share of water for agriculture would reduce further with increasing demand from other sectors. But the water demand for agricultural purposes is estimated to increase in order to produce more cereals, horticultural produce and raw material for a fast expanding food industry. Efficient management of water is, therefore, key to future growth of Indian agriculture. The requirement of water by all sectors in 2025 is estimated to be 105 M ha m (Water Resources Development in India, 2010). Share of water for agriculture is expected to get reduced from the present level of 85 % to 69 % by 2025. On the other hand, the actual agricultural water demand is estimated to increase from 470 Billion Cubic Meters (BCM) in 1985 to 740 BCM in 2025. During the same period, the demand for non-agricultural use of water will multiply fourfold from 70 BCM to 280 BCM. The water use efficiency (WUE) in Indian agriculture, at about 30-40%, is one of the lowest in the world, against 55% in China.
