1.1. Mushroom

Fruiting body of fungus appears above ground and contains spores.

Fungi are network of fine microscopic threads collectively known as mycelium.

Fungi are the part of the plant kingdom and don’t contain chlorophyll and root system.

Mushroom comes under sub division Basidiomycotina, order – Agaricales.

This chapter describes the components to design the mobile platform. The UN estimates the world population will rise from 7.3 billion today to 9.7 billion in 2050. The world will need a lot more food, and farmers will face serious pressure to keep up with demand. Agricultural robots can be used to increase the production yields for farmers in various ways.

3.1 Role of Robots in Agriculture

A challenging problem in Mechanical Engineering and robotics is the design of a mobile robot. The robot must successfully traverse through its environment, including rough terrain, grass, hills, etc. For correct positioning of the robot, the wheels of the robot must have good traction and never lose contact with the ground. For improved manoeuvrability the robot must also be able to rotate around a centre point as close to its centre of mass as possible. All of these factors have been considered in the design of a second generation outdoor de- mining robot.

A rectangular frame for the robot allows the easier positioning and accessibility of parts within the robot, which is useful in the development phase. Having the wheels up front helps the robot drive onto a slope. A circular frame for the robot would allow the robot to rotate around its true centre, such a frame, with the wheel axle running along the diameter of the frame would need support at the front and back of the robot.

Carnation (Dianthus caryophyllus L.) is one amongst the commercially important cut flowers traded worldwide. The genus Dianthus has about 300 species of annual, biennial and perennial herbs of which Dianthus caryophyllus is the most important species commercially. The genus Dianthus in Greek means ‘Flower of Zeus’ or ‘Divine Flower’. Linnaeus chose the species name, caryophyllus, after the genus of Clove, as the fragrance from carnation is reminiscent of clove. It is genetically a quantitative long day plant based on its photoperiod requirement (Blake, 1955). The Dianthus species are adapted to the cooler Alpine regions of Europe and Asia and are also found in Mediterranean coastal regions. Carnations were the first flowers to be cultivated on commercial scale in high altitude areas of tropics for export to Europe and North America.

It is cultivated throughout the world. The largest growing areas of carnation are in Bogota and Colombia. Carnation is also grown in Italy, Spain, Kenya, Sri Lanka, Canary Islands, France, Holland, Germany, Israel and USA. In India, main production areas are located around Pune and Bangalore. It is also being grown in Solan, Shimla, Mandi, Kullu, Chamba, Sirmour, Bilaspur and Hamirpur districts of Himachal Pradesh. As per the State Department of Horticulture - Himachal Pradesh, carnation occupied 44.07 hectares out of 705.77 hectare total area under floriculture in the state during 2018-19. The acreage of carnation is still expected to increase because of the favourable climatic conditions for its cultivation in different parts of Himachal Pradesh and other hilly states of the country.

In India, depending upon the regions, there is a wide difference in temperature, light intensity and humidity which not only affect the yield and quality of the flowers but also limit their availability for a particular period of the year. To produce quality flowers, carnation needs to be grown under cover, that is, in greenhouse which provides the plants with the optimum condition of light, temperature, humidity and carbon dioxide for proper growth and to achieve maximum yield of best quality flowers. Though, there are different types of the greenhouses, naturally ventilated polyhouses are preferred in mild climate in which temperature is reduced by ventilation (Ryagi et al., 2007).

Gladiolus, commonly known as ‘Sword lily’ which derives its name from latin word Gladius meaning sword shape foliage. The name gladiolus was originally given by Pliny the Elder (A.D.23-79). It is an important florist crop, cut flower in the domestic and international flower trade. It is relatively easy to grow, suitable for cut flower, pots, hanging basket, bedding and exhibition. An engrossing cut spikes bear a large number of florets on rachis, which exhibit various sizes, forms, with smooth, ruffled, deeply crinkled or laciniated tepals. As a genus it was first proposed by Tournefort and which was accepted in botanical litreture by Linnaeus through his description “Species Plantarum” in 1753 and “Genera Planterum” in 1754. The gladioli are said to be cultivated since the days of ancient Greece. The genus Gladiolus, at present comprises with 255 species (Mishra et al.,1995; Goldblatt and Manning,1998) with wide distribution occurs in Central Europe, Mediterranean region, Central and South Africa are primary centre of origin. Campbell and Bower (2003) mentions about one more species Gladiolus scabridus- a new species 1978 from the mountains of northern Kwa Zulu- Natal and southern Swaziland, restricted to well- drained rocky habitat and where it is endemic. This species has enormous commercial potential have large number of pink flowers. So now number of recorded gladiolus species are more than 260. The gladiolus was brought into cultivation first during Greek period. Gladiolus has been documented in literature since 1578, as evidenced from the record Lyte’s Nievve herbal. This was first time introduced in France and soon after spread to England, Germany, Holland and North America. In India, its cultivation dates back to 19^th century as mentioned in the ‘Firminger’s Manual of Gardening in India (1863)’ that Mr. Charles Gray of Conoor grew some gladioli from corms and seeds at his garden. The European Union gladiolus importing countries are Germany, Belgium, Luxembourg, Denmark, Spain, France, United Kingdom, The Netherlands, Italy and Portugal.

Flower arrangement is the art of using plant materials and flowers to create an eyecatching and balanced composition or display. Among all art forms, flower arrangements today take as prominent a place. The art engages ones personal involvement in welcoming guests and bringing cheer to the surroundings. It is rightly said, “Flowers are the music of the ground. From earth’s lips spoken without sound. “Professionally designed floral designs, arrangements or artwork incorporate the elements of floral design: line, form, space, texture, and color, and the principles of floral design: balance, proportion, rhythm, contrast, harmony, and unity.

Composition of Arrangements

There are a few compositions of flower arranging that should be considered. Once we understand these we can create so many different styles and our floral designs will have that professional look.

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Forecasts based on temperature and precipitation is important to agriculture. Agricultural production is highly dependent on weather, climate and water availability, and is adversely affected by weather and climate related disasters. In many developing countries where rainfed agriculture is the norm, a good rainy season means good crop production, enhanced food security and a healthy economy. Farming in many parts of the world, especially in the arid and semiarid regions is risky, because climate is highly variable. A timely seasonal forecast of favourable conditions could permit farmers to adjust cropping patterns and input use in order to benefit fully from these conditions. Under rainfed conditions, even a less reliable, but earlier forecast may be more valuable than an accurate but late forecast.

In about 340 B.C., Aristotle described weather patterns in Meteorologica. Later, Theophrastus compiled a book on weather forecasting, called the Book of Signs. Ancient weather forecasting methods usually relied on observed patterns of events. This experience was accumulated over the generations to produce weather knowledge. However, not all of these predictions prove reliable, and many of them have since been found not to stand up to rigorous statistical testing. Two officers from of British Royal Navy, Francis Beaufort and Robert FitzRoy formed the basis for all of today’s weather forecasting knowledge by middle of 19th century. A terrible storm in 1859 inspired FitzRoy to develop charts to allow predictions to be made, which he called ‘forecasting the weather’, thus coining the term ‘weather forecast’. The ‘Weather Book’ which FitzRoy published in 1863 was far in advance of the scientific opinion of the time. By the early 20th century, scientists had begun to believe that weather forecasting could be predicted based on mathematical methods. Computers were first used to create surface analyses in 1992 and by 1998 digital imagery were used for satellite, radar and surface observations, encompassing nearly every factor of weather interpretation. Modern technology, particularly computers and weather satellites, and the availability of data provided by coordinated meteorological observing networks, has resulted in enormous improvements in the accuracy of weather forecasting.

Grape is an important fruit crop grown mainly under tropical climatic conditions in India. It has spread on an area of 137 thousand ha with a production of 2951 thousand MTduring 2018-19. Famous Indian medicine scholars, Sasruta and Charaka in their medical treatises entitled ‘Sasruta Samhita’ and ’Charaka Samhita’, respectively, written during 1356-1220 BC, mentioned the medicinal properties of grapes. Native spp. resembling Vitis lanata and Vitis palmata grow wild in the northwestern Himalayan foothills. Indigenous varieties known as ‘Rangspay’, ‘Shonltu White’ and ‘Shonltu Red’ are grown in Himachal Pradesh even today. Cultivated grapes are believed to have been introduced into the north of India by the Persian invaders in 1300 AD, from where they were introduced into the south (Daulatabad in Aurangabad district of Maharashtra) during the historic event of changing the capital from Delhi to Daulatabad by King Mohammed-bin-Tughlak. Currently Mahrashtra, Karnataka, Andhra Pradesh and Tamil Nadu are the major grapes growing states of India.

However, the higher production of grapes is constrained by the incidence of several diseases and pests. The important diseases of grapes causing economic losses have been listed below and discussed in detail in the chapter.

Introduction

Broccoli (Brassica oleracea L) belonging to family Brassicaceae, is an herbaceous annual or biennial plant which is cultivated for its edible flower heads being are used as vegetable or salads. The broccoli plant has a broad green stalk, or stem, that give produces thick, leathery, oblong gray-blue to green in color leaves. The plant produces large branching green flower heads covered with numerous white or yellow flowers. Broccoli can be annual or biennial depending on the variety. Broccoli is a rich source of vitamins, minerals and antioxidants and has a reputation as super foods (Hatanaka and Ware, 2020).

It is admitted that they are susceptible to a numerous of serious diseases that leads to reduction in yield. Thus, it is the utmost requirement to control such biotic stressors in order to obtain desired quality and decent yields. The most important diseases and its control measures are being portrayed in this chapter for both home gardener and the commercial producers for cruciferous vegetables particularly broccoli (Mani et al., 2020).

Shrimp culture, a subset of aquaculture is slowly emerging as one of the major and fastest-growing food production sectors in the world. Shrimp that were once caught from the wild are now being cultured using modern aquaculture methods. Thanks to international institutions such as the World Bank, Food and Agriculture Organisation (FAO) etc., who have the encouraged the production of shrimp that fetch huge returns on investment within a short period. Third world countries are also impressed by the potential of this sector to provide food security and to earn huge foreign exchange to redress their debt burdens.

Commercial shrimp farming developed in India on account of the government’s policy to promote shrimp culture because of its potential to utilise the vast saline tracts along the coastline, provide employment opportunities to coastal rural population and to earn valuable foreign exchange. After the liberalisation of the Indian economy in 1991, development of shrimp culture gained greater momentum. Individual entrepreneurs were also encouraged to take up shrimp farming with both financial and technical support.

The market for shrimp is growing by leaps and bounds as they provide a cheap source of protein at only a little above half the cost of producing animal protein. The unique attraction of shrimp being a ‘high-value commodity’ has led to revolutionise its production, currently known as the ‘Blue Revolution’. The revolution has expanded its wings to the coastal areas of Odisha and is becoming one of the most sought out livelihood. The exponential increase in income leading to a dramatic change in the standard of living has lured the people to opt for shrimp culture. In almost all the coastal districts of the state (Odisha), shrimp culture is prominent now.

In this chapter, an attempt has been made to review some of the earlier studies related to shrimp farming and its socio-economic and environmental impacts. The related pieces of literature are classified into the following five categories.

3.1. Paddy

3.1.1. Thrips: Stenchaetothrips biformis (Thripidae: Thysanoptera)

6.1. Fungicides

Fungicide originated from two latin words viz., fungus and caedo.

Word caedo means to kill.

Fungicide is a chemical agent which has the ability to reduce or prevent the damage caused to plants and their products.

Physical agents like ultra violet light and heat should also be considered as fungicides.

Antisporulant and fungistatic compounds do not kill the fungi, they are included under the broad term fungicide

Introduction

Cyanobacteria are often called “blue-green algae”, this name is convenient for talking about organisms in water that make their own food, but does not ref lect any relationship between the cyanobacteria and other organisms called algae. Cyanobacteria are relatives to bacteria, not eukaryotes, and it is only the chloroplast in eukaryotic algae to which cyanobacteria are related. Some cyanobacteria are aquatic and photosynthetic, that is, they live in water, and can manufacture their own food. They are quite small and usually unicellular, though they often grow in colonies large enough to see. In fact, it may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth (Berry et al., 2008). The great contribution of cyanobacteria is the origin of plants chloroplast with which plants make food for themselves is actually a cyanobacterium living within the plant’s cells. Sometime in the late Proterozoic or in the early Cambrian, cyanobacteria began to take up residence within certain eukaryote cells, making food for the eukaryote host in return for a home. This event is known as endosymbiosis, and is also the origin of eukaryotic mitochondrion (Issa et al., 2002).

ZINC (Zn)

Chandler et al., (1932) deduced the requirement of zinc by plants while working solution for little leaf or “rosette” on peach. Zinc plays significant role in assimilation of NO₃ and for synthesis of tryptophan. Involved in biosynthesis of indole acetic acid which is responsible for f lowering and fruiting, it is an activator of several enzymes (triphosphate dehydrogenase and tryptophan synthetase), involved in photosynthesis and nitrogen metabolism.

Deficiency results in poor growth of the terminal bud. Decrease in stem length resulting in resetting and whorling of leaves. Zinc deficiency disorder in rice is called khaira. Common when zinc availability is < 0.7 ppm. White bud in maize and malformation of fruits, reduction in water uptake. Interveinal chlorosis often with necrosis and pigmentation and reduced leaf size in broad leaved crops known as little leaf and malformation of leaves.

The crops which are known to respond for zinc application are maize, rice, soyabean, castor, onion, barley, wheat, potato, sorghum and cotton

Much of the post-harvest losses of fruits and vegetables in developing countries is due to the lack of proper storage facilities. While refrigerated cool stores are the best method of preserving fruits and vegetables they are expensive to buy and run. Consequently, in developing countries there is an interest in simple low-cost alternatives, many of which depend on evaporative cooling which is simple and does not require any external power supply. India is the second largest producer of fruits and vegetables in the world after Brazil and China respectively. Storage of fresh horticultural produce after harvest is one of the most pressing problems of a tropical country like India. India’s total fruits and vegetables production is lost during harvest, storage, grading, transport, packaging and distribution in a year which reduces the growers share. Due to their highly perishable nature, about 20-40% of total fruit and vegetable production go waste during various steps of the post-harvest chain, smooth transport and insufficient cool storage space/ facility at farmer’s level and high cost of refrigerated storage so further enhances loss of fruits and vegetables. Temperature and humidity play major role in storage of fruits and vegetables Temperature can be controlled by using energy consuming methods such as air-cooling, hydro-cooling, vacuum-cooling, chilling, ice cooling, freezing, etc.

Introduction

Since the last century, nutritional science has made a remarkable contribution to the biological sciences through identification of diverse nutrients and their sources, functions, requirement, deficiency symptoms and their remedial measures etc. The advent of high-throughput sequencing technologies together with bioinformatic tools identified the presence of 100 trillion of microorganism belonging to all forms of life in the gastrointestinal tract. In fact, the whole gut microbial consortia are considered as a virtual organ in human and animals and is responsible for the development and functioning of series of essential physiological activities including digestion, absorption, metabolism, immunity, homeostasis, brain and gut development, resistance against disease etc. According to the modern scientific dogma, the human being is in fact a “Superorganism”, carrying consortium of numerous symbiotic Eukarya, Bacteria, Archaea and Viruses. The gut microflora has been co-evolved with human and presumed to maintain an intricate balance among different microbial communities. Upon introspection about the functionality of the gut microflora, it is amply clear that a few of these microorganisms have the ability to make healthy state; while other members are responsible for health-related problems including food poisoning, diarrhoea, abdominal pain, indigestion, inflammatory bowel disease, predisposition to colon cancer, compromising immunity, allergy etc.

Cucumber (Cucumis sativus var. sativus L., 2x = 2n = 14, normally monoecious, cross-pollinated) is a member of the economically important family Cucurbitaceae which includes squash/pumpkin (Cucurbita ssp.), watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai], melon (Cucumis melo L.) and gourds. After tomato (Solanum lycopersicum L.) and watermelon, cucumber and melon are cultivated more widely than any other vegetable species globally accounting for about 2.5 million ha and producing 43 million tons giving a productivity of over 17 tons/ha under field and greenhouse culture. Production of cucumber is the second largest of all cucurbits, where China, Iran, Russia, Turkey and the United States represent about 75% of the world production.

During 2017-18, India produced 1.25 million tons of cucumber from 0.08 million ha (80, 000) area resulting into a productivity of close to 16 tons/ha (MAFW, 2018). Top ten cucumber producing states in India in the same period are Haryana (17000 ha), MP (9500 ha), Karnataka (8300 ha), Assam (6900 ha), Maharashtra (4500 ha), Andhra Pradesh (4400 ha), Bihar (3900 ha), Punjab (3600 ha), Kerala (3400 ha) and UP (3300 ha).

ABSTRACT

Malting is the process accompanied by restricted sprouting of cereals in humid atmosphere along with controlled set of conditions. It is a process of soaking, germination and drying that causes changes to the microstructure of grains. Malting causes changes in functional and nutritive value of grains. Malting results in increase in protein content, mineral availability, in vitro protein digestibility, oil absorption capacity, water absorption capacity, water solubility index and fall in level of antinutritional factors, viscosity and bulk density. The malting conditions are significantly affected by varietal difference, maturity of grains and structural composition. Therefore, optimum malting conditions should be determined for grains in order to avail the health and nutrition benefits.

3.1. What is weathering?

Weathering may be defined as the transformation process of solid rocks, involving the disintegration and decomposition of rocks and minerals, into soil.

There are different types of weathering: physical, chemical and biological.

3.1.1. Physical weathering

In physical weathering the chemical composition of the weathered products remains same as that of the parental rocks. It is involved in fragmentation of rocks into comparatively smaller sizes. It does not transform the parental rock into a newer one that may differ from the parental rock in chemical composition. The process is totally physical in nature. But this is also true that physical weathering encourages chemical weathering, and both may be carried out simultaneously because physical weathering promotes more surface area of parental rocks for more interaction with agents of chemical weathering.

10.1. Introduction

The soils possessing characteristics that are not suitable and economical for crop growth are termed as Problem soils. These characteristics may be of physical, chemical and biological. For cultivation of crops in these soils, it is necessary to follow specific management interventions and proper reclamation measures. Frequently we come across another term, ’degraded soil’. Degraded soil is also a problem soil. However, there exists a hair-line difference between problem and degraded soil. Problem soils refer to the soils in which the inherent soil characteristics, obtained from its genesis, pose problems for their optimal use, while degraded soils are developed due to anthropogenic activities by unwise management interventions.

10.2. Types of problem

Mainly there are four types of problem that may exist in soils: physical problems, chemical problems, biological problems and nutritional problems as a result of physical, chemical and biological constraints in soils.

Introduction

Water and food security are the key challenges under climate change as both are highly vulnerable to continuously changing climatic patterns. Climate change has resulted in increases in globally averaged mean annual air temperature and variations in regional precipitation and these changes are expected to continue and intensify in the future. The projected changes in climate patterns over India include increase in surface temperature, variations in rainfall, increasing occurrence of extreme weather events like floods and droughts, rise in sea levels and impact on the Himalayan glaciers. Sectors of the Indian economy are most likely to be impacted by such changes in climate are those dependent on natural resources, namely agriculture, water and forestry. The likely impacts such as reduction in food production, water scarcity, loss of forest biomass Climate change is expected to bring more intense and more frequent extreme weather events including droughts and floods in India. The global atmospheric concentration of carbon di-oxide CO₂ for increased from preindustrial value of about 280 ppm to about 410 ppm at the present (2021). The global increase in CO₂ concentration is primarily due to fossil fuel use and land use change. Atmospheric methane was 1803 ppb in 2011, this is 150% greater than before 1750. Atmospheric nitrous oxide (N₂O) was 324 ppb in 2011, this is 150% greater than before 1750 (Table 1). These increase in GHGs have resulted in warming of the climate system by 0.74°C between 1906 and 2005.

Introduction

Climate change is a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures. Eleven years from 1995-2006 rank among the twelve warmest years in the instrumental record of global surface temperature (since 1850). The 100-year linear trend (1906-2005) of 0.74 [0.56 to 0.92] °C is larger than the corresponding trend of 0.6 [0.4 to 0.8] °C (1901-2000) and over the 21st century average temperature of earth surface is likely to go up by an additional of 1.8-4°C (IPCC, 2007). This temperature increase can be attributed to the altered energy balance of the climate system resulting from changes in atmospheric concentrations of the green house gases (GHGs). Among the principal components of radiative forcing of climate change, CO₂ has the highest positive forcing leading to warming of climate. CO₂ has the least global warming potential among the major green house gases but due to its much higher concentration in the atmosphere; it is the major contributor towards global warming and climate change. Agriculture sector in India contributes 28% of the total GHG emissions (NATCOM, 2004). The global average from agriculture is only 13.5% (IPCC, 2007). In future, the percentage emissions from agriculture in India are likely to be smaller due to relatively much higher growth in emissions in energy-use transport and industrial sectors. The emissions from agriculture are primarily due to methane emissions from rice fields, enteric fermentation in ruminant animals and nitrous oxides from application of manures and fertilizers to agricultural soils (NATCOM, 2004).

Introduction

Since the dawn of the civilization when mankind started agriculture, soil erosion has been the single largest environmental problem and has remained so till date (Sullivan, 2004). This is so because removal of the topsoil by any means has, through research and historical evidence, been severally shown to have many deleterious effects on the productive capacity of the soil as well as on ecological wellbeing. Doran and Parkin (1994) captioned the impact of soil erosion in their popular maxim that “the thin layer of soil covering the earth’s surface represents the difference between survival and extinction for most terrestrial life”. Soil degradation implies decline in its capacity to provide ecosystem services (ESs) of interest to humans and useful to nature’s functions. Principal processes of soil degradation are erosion, salinization, nutrient and carbon (C) depletion, drought, decline in soil structure, and tilth. Examples of ESs provided by soil include ecological/supporting (biomass production, nutrient cycling), regulating (water purification and flow, C sequestration, temperature fluctuations), provisional (food, fiber, fuel, and forages), and cultural (aesthetical, spiritual, and cultural). Erosion-induced degradation diminishes soil’s capacity to provide ESs, and support ecosystem functions.

Although fertile top soils could be lost when scraped by heavy machineries (Ngwu et al., 2005), the key avenues of topsoil loss include water erosion and wind erosion. Sometimes erosion can be such gradual for so long a time as to elude detection in one’s lifetime, thus making its adverse effects hard to detect. Eswaran et al., (2001) propose an annual loss of 75 billion tons of soil on a global basis which costs the world about US $400 billion per year. A review of the global agronomic impact of soil erosion identifies two severity groups of continents and reveals that Africa belongs to the more vulnerable group (Biggelaar et al., 2004). Soil erosion by water seems to be the greatest factor limiting soil productivity and impeding agricultural enterprise in the entire humid tropical region. This is evident in many regions of Africa (Dregne, 1990), mainly in the humid and subhumid zones of Sub-Saharan Africa (SSA) where population pressure and deforestation exacerbate the situation and the rains come as torrential downpours, with the annual soil loss put at over 50 t ha⁻¹ (FAO, 1995).

Introduction

The inevitability of detrimental effects of climate change is looming large not only on the sustenance of agriculture, but also on the survival and progress of mankind. Estimates by the Organization for Economic Cooperation and Development (OECD) reveal that the atmospheric concentration of GHG would exceed 680 parts per million (ppm) CO₂-equivalents by 2050, which is about 50% higher than baseline year 2010 (OECD, 2012). Additionally, global temperature is predicted to increase by 2°C within this period, resulting in meansea level rise and erraticweather conditions. Consequently, the catastrophic effects on food consumption pattern by the end of 2050 will create malnutrition in at least 290 million people. Agricultural crops provide 63% of the human protein, and additionally supply almost 100% protein to the livestock, which are the second major sources of protein in human diet. Altogether, the detrimental effect of climate change on agriculture would make about 300 million additional people malnourished. Add to that a 2.7 billion increase in human population by 2050, coupled with shortage of water availability that would affect 3.9 billion people by 2050, and one can easily perceive the grim scenario for our kind in not so distant future.

Introduction

Plant architecture is defined as a three-dimensional organization of plant body in terms of its size, shape position of leaves, flower organs and branching pattern. Earlier this was the only criterion for systematic and taxonomic classification of plant species and the best means of identifying them (Stecconi, 2006). Study of plant architecture emerged as a new scientific discipline some 30 years ago. The subject derives its base from earlier works on plant morphology (Halle and Oldeman, 1970) but currently it is integrated with several disciplines of plant sciences ecology and engineering. Modification in plant architecture causes alteration in primary and secondary growth. This occurs due to differences in phyllotactic arrangement, branching pattern and floral differentiation. Plant architecture can be modulated by various parameters like climate, agronomic practices and human interventions. Manipulation of plant architecture is a major area in plant science which is currently adopted for productivity improvement by breeders, agronomists, horticulturists and landscape managers. However, the basis for such manipulation lies in the knowledge of the basic architecture of plants and its significance.

1. Bone grafts

Bone grafting represents one of the earliest devised reconstructive approaches to the musculoskeletal system and remains among the most commonly used orthopedic procedures. Bone is the second most frequently transplanted tissue. The first recorded attempt to use bone graft is by the Dutch surgeon Job Van Meek’ren in 1668.

Definition

A graft is a living tissue that is transplanted to another site either within the same individual or into another individual for repair of a defect. An implant is a non viable material placed in a living system. Implants are composed of bone cement, metal or ceramic material. Grafts are structurally important for mechanical stability, but their use evolved to include the stimulation and enhancement of bone in response to injury.

Indications

Bone grafts are used, in general as framework, both to provide stability and to augment healing. It is used in the management of non union, delayed union, treatment of pseudoarthrosis, filling of osseous defects or cavities, arthrodesis, stabilization of spinal segments and addition of bone stock in total joint displacement.

Repairing fractures in small animal’s presence challenges to the veterinarians in their day to day service. These challenges include properly repairing fractures, each of which is unique, choosing the right fixation device, keeping an extensive inventory of costly instruments, and providing high standards of care for fracture repair. But fracture repair also gives veterinarians the opportunities to do something a little unusual in daily practice and to experience the immediate gratification of easing pain and promoting activity in injured animals.

Successful management of fractures mainly depends upon early diagnosis, type of fracture, timing of surgery and selection of proper method of fixation. The fixation of fractures can be achieved either by external or internal fixation methods. An ideal method of fracture fixation is one that can maintain early anatomical reduction, minimal soft tissue trauma, rigid stability and early motion of bone and joint. Restoring a fractured bone’s normal shape is important for return to function because it contributes to normal alignment of adjacent joint surfaces. Whereas, rigid stability of fracture fixation eliminates fragment movement and reduces pain. Soft tissue trauma adjacent to fractured bone should be minimum, which play a vital role in early vascularisation and prevents infection. Finally, early return to function maintains muscular tone of the limb allows normal weight mobility and joint nutrition and uses normal weight bearing forces to maintain bone density. These can be achieved with use of internal fixation devices.

In 1882, Robert Koch first isolated the bacterium, stained with alkaline methylene blue and vesuvin as counter stain and showed its etiologic relationship with tuberculosis. Ehrlich first developed acid-fast stain in 1882 and used for better staining of the bacteria which was adopted by Robert Koch. The acid-fast staining technique was modified later by Franz Ziehl and Friedrich Neelsen, accordingly, it is known as Ziehl-Neelsen (Z-N) staining. In 1890, Koch prepared a glycerine broth extract of the tubercle bacillus, known as ‘tuberculin’. He tried to prepare it as a curative agent; but it was used later in diagnosis. In 1895, Johne and Frothingham described the first case of paratuberculosis in cattle which became known as ‘Johne’s disease’. The causative bacterium was later isolated by Twort and Ingram in 1910.

In India, bovine tuberculosis is reported from several states since 1959 (Dhanda and Lall, 1959). The bovine paratuberculosis in India was first reported by Nanda and Singh (1940) from Haryana.

History of rickettsial infections went back to 16^th century and it has long been associated with famine and war. Epidemic typhus had major impact to decide over the outcome of several wars. The epidemic alone killed or caused great sufferings to over 1,00,000 people during World Wars. However, the causative agent was not determined until the early part of the 20^th century. Rocky Mountain spotted fever (RMSF) was the first detected rickettsial infection in 1896 in Idaho Valley, USA. It was originally known as ‘black measles’ due to its clinical appearance in the form of characteristic spotted rash throughout the body. Howard Taylor Ricketts, an American pathologist for the first time described the causative agent of Rocky Mountain spotted fever and was able to isolate it in the laboratory animals during 1902-1909. He was a dedicated scientist and on several occasions injected himself with the pathogen for experiment. The causative pathogen of Rocky Mountain spotted fever, Rickettsia rickettsii was named after him. Later, the family Rickettsiaceae as well as the order Rickettsiales was named after him. Ernest William Goodpasture, an American pathologist and physician, invented the methods of isolation and culturing the rickettsial pathogens in chicken embryos and fertilized chicken eggs.

Sugar also acts as preservative at high concentration 70% or more in food products (fruit and vegetable products). High concentration of sugar in food materials create unfavourable conditions for microbial survival and prevent spoilage. Based on this principle of preservation, sugar based products are prepared from fruits and vegetables so that they can be preserved for long time. This method of preservation with high sugar concentration is principally based on the reduction in moisture content to arrest or stop microbial spoilage. Preparation of sugar based products is one of the most important aspects of home scale as well as industrial level processing of fruits and vegetables. Sugar based value added products include.

Food, at the fundamental level, is viewed as a source of nutrition to meet daily requirements at a minimum in order to survive but with an ever greater focus on the desire to thrive. Nutritional security denotes the consumption and physiological use of adequate quantities of safe and nutritious food by every member of the family and encompasses the process of equitable distribution among members of household and communities. This would entail the need to ensure a varied food intake, comprising all the essential macro- and micronutrients (protein, carbohydrates, minerals and vitamins), plant pigments (lycopene, β- carotene, anthocianin, lutein, capsanthin, zeaxanthin, etc.) and other functional phytochemicals (secondary metabolites, like flavonoids, isothiocyanates, glucosinolates, etc.) through a diversified diet. The growing awareness in recent years of the health promoting food has directed increased attention to vegetables as vital components of daily diets.

Main Nutrient Components of Vegetables

Nutrient components of our food can be grouped into five main divisions, namely, (i) Carbohydrate, (ii) Protein, (iii) Fat, (iv) Vitamins and (v) Minerals. Balanced diet is the food containing all these nutrient components in balanced form to run the physiological process in good tune. So, only eating to one’s heart’s content may not be the criterion of a balanced diet. Our dietary constitution which is mostly cereal based is really alarming. Cereals, which supply chiefly carbohydrate, constitute only a part of the diet. Moreover, the present average carbohydrate supply through cereals is also not adequate. Chief deficiencies in our diet are calories, protein, vitamin A and riboflavin. According to the studies of Indian Council of Medical Research, New Delhi and National Institute of Nutrition, Hyderabad, meager intake of vegetables, the low cost protective foods, is largely responsible for malnutrition among the majority of our population. The dieticians advocate intake of 125g leafy vegetables, 75g other vegetables and 100g root and tuber vegetables (total 300g) everyday to make our diet balanced. In households below the poverty line, per capita vegetable consumption is very low, apprehended to be even lower than 40g per day.

Development can be defined as the process and timing of differentiation of the component events causing qualitative changes in form and function of the plant and therefore, manifestation of economic plant parts. Sowing is the beginning of the process, after which plants emerge, grow and develop with or without transplanting and may be harvested in vegetative (e.g., cole, bulb, tuber, root, salad crops) or reproductive phase (solanaceous fruits, peas and beans, cucurbits, okra, etc.). Growth and development of plants is dependent on abiotic (physical) and biotic (biological) factors. Abiotic factors include the physical environmental conditions and biotic factors include animals, insects, and diseases. Each plant has certain environmental requirements. To attain the highest potential yields a crop must be grown in an environment that meets these requirements. A crop can be grown with minimal adjustments if it is well matched with its climate or growing condition. Unfavourable environmental conditions can produce a stress on plants resulting in lower yield. In such cases the environment can be artificially modified, as done in protected structures like poly house, shade net house, etc. to meet the crop requirements.

Different abiotic environmental factors viz., light, temperature, water and soil greatly influence plant growth and geographic distribution. These factors determine the suitability of a crop for a particular location, cropping pattern, management practices, and levels of inputs needed. A crop performs best and is least costly to produce if it is grown under the most favourable environmental conditions. To maximize the production of any crop, it is important to understand how these environmental factors affect plant growth and development.

Information literacy has been the subject of many studies over many years. The originating concept of information literacy is generally attributed to Paul Zurkowski, in 1974 (Spitzer, Eisenberg & Lowe 1998). Indeed, since 1974 information literacy has been an area of increasing interest to librarians and information professionals and there is a huge amount of literature on the topic. However, the majority of publications have come from the industrialised, English-speaking countries, especially from the United States and Australia. Information literacy is related to information technology skills, but has broader implications for the individual, the educational system, and for society. Information literacy is a natural extension of the concept of literacy in our information society. Information literacy education is the catalyst required to transform the information society of today into the learning society of tomorrow. IL is generally seen as pivotal to the pursuit of lifelong learning, and central to achieving both personal empowerment and economic development. Information literacy is a key component of, and contributor to, lifelong learning. Information literacy is increasingly important in the contemporary environment of rapid technological changes and proliferating information resources. Because of the escalating complexity of this environment, individuals are faced with diverse and abundant information choices—in their studies, in the workplace, and in their personal lives. It is common to all disciplines, to all learning environments, and to all levels of education. It enables learners to master content and extend their investigations, become more self directed, and assume greater control over their own learning.

The phrase “information skills” (rather than information literacy) is used, for example, by the Standing Conference of National and University Libraries (SCONUL) in the name of its Task Force, and was used by the Joint Information Systems Committee (JISC) when tendering for a project looking at training in UK further and higher education.

Information literacy competency ensures maximum utilization of the information resources as well as optimization of information handling capabilities.. Information literacy competency extends learning beyond formal classroom settings and provides practice with self-directed investigations as individuals move into internships, first professional positions, and increasing responsibilities in all arenas of life. Because information literacy augments students ’ competency with evaluating, managing, and using information, it is now considered by several regional and discipline-based accreditation associations as a key outcome for college students and for “on campus “ students..

A world view of Transportation system of renowned urban centers

While discussing urban regeneration and observing cities, it is impossible to overlook the importance of the transportation system and its impact on the urban form of a city. For example, if one observes a typical industrial city plan, one would notice that radial corridors of development generated from the city core stand out in contrast to the intricate detailing of vehicular roads added later on in due course of time.

The increase in vehicular traffic brings in new patterns of fast moving lanes. To clear the congestion created by ever increasing number of motor cars, larger cities need new road patterns and parking spaces, even public transportation needs new interventions and congestion of buses gives way to systems like mass rapid rail

Food fermentation is the oldest method of food preservation and have originated several million years ago. It plays an important role in ensuring the food security of millions of people around the world particularly marginalized and vulnerable groups. It is relatively efficient, low energy consuming process which needs no refrigeration or other energy intensive food preservation technologies but increases the shelf-life of foods. Fermentation ensures not only increased shelf-life and microbiological safety of food but may also make some foods more digestible and lower or eliminate the toxicity of substrate like cassava.

The food fermentation technology utilizes the ability of growth of microorganisms on various substrates for the production of a variety of fermented foods, beverages and pickles like bread, beer, cheese, idli, tempeh, miso, sauerkraut, fermented sausages, etc. Fermented foods are popular throughout the world since antiquity and in some regions these are the major component of the diet of millions of individuals. Indigenous fermented foods such as bread, cheese and wine have been prepared and consumed since ages and have occupied important place in culture, religion and tradition of people all over the world.

1. INTRODUCTION

Wild fruits are highly nutritious and contain vitamins, carbohydrates, protein and minerals in higher quantity than majority of other common cultivated fruits. They are also a rich source of several bioactive substances, compared to the cultivated fruits. In India,these wild fruit trees grow abundantly across an altitudinal gradient of Himalaya and the majority of them bear fruits during summer. Fruit varieties are consumed by the local inhabitants of the region. At the same time, there are numerous under exploited species of wild fruits having high potential for exploitation viz., Bael (Aegle marmelos CL.), Berberis asiatica DC, Seabuckthorn (Hippophae sp.,) Rubus sp., Prunus armeniaca L., Karonda (Carissa carandas L.) Bitter Almond (Prunus amygdalus Batsch Smith), Feijoa sp. Among the wild fruits, Hippophae sp.was found to be economically efficient, followed by Aegle marmelos, Rubus ellipticus Smith, respectively. Wild apricot (Prunus armeniaca L.), a semi-domesticated and less utilized fruit of the higher Himalaya, provides better economic returns on an annual basis. Attempts have been made to utilize these wild fruits as a source of income, particularly for poor rural inhabitants and unemployed youths of the region by making a variety of edible products such as jam, jelly, juice, squash, sauce, wine etc. Here in this article, production of wine, vermouth and brandy from wild fruits would be focused. But before discussing preparation of wine and brandy in detail, we shall be describing the general process of wine and brandy making first, then the products from the specific wild fruits.

13.1 Introduction

Eutrophication, means an increase in chemical nutrients — typically compounds containing nitrogen and phosphorus in an ecosystem. It may occur on land or in water. The term is however often used to mean the resultant increase in the ecosystem’s primary productivity (Fig. 13.1), in other words excessive plant growth and decay and even further impacts, including lack of oxygen and severe reductions in water quality and in fish and other animal populations.

18.1 Introduction

The commercially available water quality simulation models with various dimensions (1D, 2D and 3D) and database software designed to quantify movement and concentration of contaminants in lakes, streams, estuaries, and marine environments. The following water quality models were described below (Table 18.1).

18.2 Environmental Fluid Dynamics Code

The Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling system, which includes hydrodynamic, sediment-contaminant, and eutrophication components. It has been applied to over 100 water bodies including rivers, lakes, reservoirs, wetlands, estuaries, and coastal ocean regions in support of environmental assessment and management and regulatory requirements. IT is a state-of-the-art hydrodynamic model that can be used to simulate aquatic systems in one, two, and three dimensions. It has evolved over the past two decades to become one of the most widely used and technically defensible hydrodynamic models in the world. It uses stretched or sigma vertical coordinates and Cartesian or curvilinear, orthogonal horizontal coordinates to represent the physical characteristics of a waterbody. It solves three-dimensional, vertically hydrostatic, free surface, turbulent averaged equations of motion for a variable-density fluid. Dynamically-coupled transport equations for turbulent kinetic energy, turbulent length scale, salinity and temperature are also solved. The model allows for drying and wetting in shallow areas by a mass conservation scheme.

6.1 Quantities and rates of runoff

Before a start can be made on the design of the channels and ditches and other works which can deal with surface runoff we need to know the probable quantity of water. If the object is to impound or store the runoff then it may be sufficient to know the total volume of water to be expected, but the usual conservation problem is conveying water from one place to another, and in that case the rate of runoff is more important, and particularly the maximum rate at which runoff is likely to occur. That is the flow which a channel must be designed to accommodate.

In a hypothetical catchment area* with an impervious surface and no losses the maximum rate of runoff would be directly proportional to the rate of rainfall. In natural catchments there are other factors: some of the rain is intercepted by vegetation, some infiltrates into the soil, some starts moving over the surface but is trapped in depressions, and some is lost by evaporation. Estimates of rates of surface runoff therefore depend on two processes: estimating the rate of rainfall, and estimating how much of the rainfall becomes runoff.

There are several empirical methods for doing both and for combining the two factors, but because they are empirical two points must be stressed. Firstly, as with all empirical solutions, data, tables, and formulae developed in one situation should not be applied in different conditions without careful checks on whether the method is valid in the new situation. Secondly, each of the three main methods which will be

7.1 Introduction

Breeding plans are based on controlled mating (i.e., mating between selected strains) and selfing of selected strains or a combination of both. Continued selfing is practised to isolate purelines and inbreds. On the other hand, crossing (hybridization) is necessary to produce hybrids and synthetics. In crossing, self-pollination is prevented in the female parent. Male sterility and self-incompatibility easily exclude self-pollination, and so they are used in hybrid seed production.

7.2 Male Sterility

Koelreuter (1763) for the first time reported male sterility in flowering plants. Male sterility is a reproductive deficiency of some plants in which male organs in bisexual flowers become defunct. It relates particularly to nonviable pollen grains that are formed through a chain of vital processes during microsporogenesis. These processes are so delicately balanced under genetic control of many loci that mutation of any one locus may lead to the formation of non-functional microspores, and hence male sterility. In male sterility, pollen grains are non-functional (inactive); but the female gametes (egg cells) are normally functional.

1. Introduction

There is a global evidence of deterioration of nutrition and food security condition following the Pandemic and subsequent economiclockdown (Summerton, 2020; Laborde et al., 2020). In India, the status of nutrition and food security has been a matter of concern for decades. India scored an alarming rankof 102 out of 116 countries in Global Hunger Index (IFPRI, 2019). The problem has also been a gendered one, with an abysmally higher proportion of malnourishment and hunger in women and children in India. As per NFHS 4 (2015-16), every second woman in reproductive age in India was suffering from anaemia, two in five children were suffering from stunting and every tenth child in India was suffering from acute malnourishment (IIPS, 2017). It is not difficult to imagine that this existing malnutrition-crisis has only worsened in the post-lockdown period. There is a consensus among academicians, policy makers and planners that the nutrition crisis needs to be linked to gender-based exclusions & vulnerabilities (Quisumbing et al., 2020). This chapter attempts to discuss some of these complicacies of food-nutrition-gender linkages to put forth gender advocacy for food & nutrition policies.

Evidence of linkages between gender and nutrition are there althoughit is difficult to establish precise empirical connect. Also, the pathways through which gender influences nutrition and food security are multiple and complex. Food/nutrition-policy, therefore, has a long way to go till it is gender-informed. To begin with, the understanding of the concept of gender is limited at the policy-level. Moreover, most of the nutrition-food related policies in India have not mainstreamed gender or are working ina gender-specific manner rather than redistributive manner¹.

It is in this pretext the chapter reviewed the available evidence on gender-nutrition linkages to put forth an argument not only in favour of gender-aware nutrition policies, but also to guide as to how Gender should be integrated. The chapter is structured in five sections with sections that discusses the concept, i.e., importance of context in policy-level for conceptualising gender-needs. This is followed by a review of existing work from a Gender Needs framework and selected empirical evidence from recent primary study of the author are also presented as another separate section. The relevance of reviewing gender-nutrition linkage after COVID19 Pandemic also find place in the chapter. Finally the summary concludes the discussion on gender advocacy in nutrition.

Botanical Name: Coffea arabica, Coffea canephora

Family: Rubiaceae

Chromosome No: 44, 22

Place of Origin: Africa

Common Name: Coffee

8.1 Introduction

Coffee is widespread throughout the tropics with more than 70 species. All cultivated species originate from Africa. Economically important today is Coffea arabica (Arabica, 64 % of world production) and Coffea canephora, (Robusta, 35 %). It is cultivated worldwide on approximately 10.3 million hectares and represents the sole economic income for more than 25 million families. The crop is produced and exported by more than 60 nations and ranks as one of the top cash crops in developing countries with 3.19 lakh MT production per annum in India in 2018-19 from more than 459 thousand hectares crop area. The coffee plant is a fast-growing tropical bush tree, with two types of shoots: upright growing orthotropic main shoots (stem), and horizontally growing plagiotropic shoots (branches). Traditionally, coffee trees are cultivated only for the berries, which are processed using dry or wet techniques directly in the growing areas to the final raw product, green coffee; this serves as the basis for various coffee products. Both the coffee species tolerate shade and share quite similar growth requirements with various forest crops and trees, thus predisposing them to be grown in agro-forestry ecosystems.

Green gram or mungbean (Vigna radiata (L.) Wilczek, var. radiata, 2n = 2x = 22, a self-pollinated crop belonging to Family Leguminosae or Fabaceae) occupies globally 7.3 million ha area with production of 5.3 million tons (2015-17) resulting into a productivity of 726 kg/ha with India and Myanmar each supplying about 30% of the global production. China contributes about 16% and Indonesia 5% of the global production. It is relatively tolerant of heat and drought and the grains are a good source of protein and iron for human nutrition. In East and Southeast Asia, it is consumed as nutritious bean sprouts and in South Asia as dahl.

INTRODUCTION TO FINANCIAL MANAGEMENT

CONCEPT AND DEFINITION OF FINANCIAL MANAGEMENT: Financial management is an integral part of general overall management. The term ‘Financial management’ is managerial activity that is concerned with planning and controlling of financial resources of a firm. Financial management is concerned with managerial decisions that result in the acquisition and financing of long and short-term credits of the farm or any enterprise. Financial management is concerned with the efficient use of all important economic resources that is capital funds of a firm (Solomon Ezra)

Financial management is an application of general managerial principles to the era of financial decision-making. (Howard &Uptron).

Financial management is an area of financial decisions making, harmonizing individual motives and enterprise goals.(Weston & Brigham).

Financial management is an operational activity of a business that is responsible for obtaining and effective utilizing the funds necessary for efficient operations.(Joseph & Massie)

4.1. Aspergillosis disease causing fungi Aspergillus

Aspergillosis is usually caused by the fungus Aspergillus (Fig. 161) and usually occurs in people with lung diseases or weakened immune system

The different types of aspergillosis can cause different symptoms. The symptoms are similar to asthma symptoms, and include:

4.1.1. Allergic bronchopulmonary aspergillosis (ABPA)

The symptoms of ABPA includes Wheezing, Shortness of breath, Cough and Fever (in rare cases).

4.1.2. Allergic Aspergillus sinusitis

The symptoms of Alleric Aspergillus Sinusitis include stuffiness, Runny nose, Headache and Reduced ability to smell.

Artificial Intelligence (AI) is technology which can store, retrieve, manipulate, manufacture, transmit or receive, analyze any digital information and can apply machine vision for increasing efficiency and workability of the system. The AI permits systematically scope of ‘3S’ i.e. Safety, Security and Surveillance, which is also known as manmade intelligence. In fact, it needs more reliable and accurate data or information for processing and correction for predicting performance of any system and devices.

The term robot is czech word, first time used by play write Karel Capek, in year 1920, applicable to the forced labour or serfs or slaves. The first commercial, digital and programmable robot, named ‘Unimate’ was built by George Devol in 1954.
