In spite of the fact that the forests are the wealth of a nation and play a vital role in the economy of the country, not much attention has been paid to their promotion, protection and conservation. The forests of India have been reduced to 19.27 per cent (Gupta and Khajuria, 2000) and/or 23 per cent including 20.55 per cent forest cover and 2.48 tree cover (Sharma, 2005). It is much less than as prescribed in the National Forest Policy (1952), according to which onethird i.e. 33 per cent of the total land area of the country must be under forest.

The primary role of the respiratory system is to provide O2 to the tissues for metabolic needs and remove the CO2 formed by them. Body needs oxygen to oxidise the food nutrients and derive energy. In this process carbon dioxide is produced in the body, which is toxic and must be removed quickly and efficiently. The oxygen utilization & carbon dioxide production takes place within the mitochondria of cells of the various tissues.

Lactation is the process of milk secretion by the mammary gland. Lactation is the final phase of the complete reproductive cycle of mammals. Newborns of most species are dependent on maternal milk during the neonatal period. Lactation is therefore essential for survival of the species.

The residues from production and processing of raw agricultural products such as fruits, vegetables, meat, poultry, dairy products and crops are called agricultural
wastes. The by-products of agricultural activities are also referred to as agricultural waste.

The two different compartments of the body fluids are extracellular fluid (ECF) and intracellular fluid (ICF) with variation in solute concentrations.
The extracellular fluid is the fluid in the cardiovascular system or in between the cells, called interstitial fluid.

Cytokines are the short lived chemical messenger molecules, released by a group of cells which can modulate the functions of the same cell(by which they are produced) or other cells.

In the study of immunology, several techniques are used. These techniques are called immunotechniques. These techniques are used not only in immunology but are the methods for research and diagnostic purpose in many fields such as microbiology, biochemistry, endocrinology, hematology and in pathological laboratories.

Scooping: It involves `Removing’ of basal plate and destroying the `Central Shoot’ of the bulb, thus encouraging the formation of bulblets round the cut edges of the scale leaves. Scooping is achieved by using a special knife or a spoon with a `Sharpened edge’ to leave a `Concave depression’ at the base of bulb. The depth of the cut is important, because the bulblets are formed on `cell tissues’ at the lowest point of the `scale leaves’.

Volumetric analysis, also known as titrimetric analysis, is an analytical method of estimating the concentration of a known solute (analyte) in a solution by measuring the volume of a second known solution of known concentration (standard solution), that reacts completely with the known solute of unknown concentration. The prerequisite of titration is that the two different analytes, present in solution form, must involve in a fast chemical reaction. The standard solution is more commonly known as ‘titrant’ and the solution whose concentration needs to be determined is frequently called ‘titrand’.

Foxtail millet (Setaria italica) is one of the oldest cultivated millet with several varieties throughout the world with grains varying in colour from pale yellow, to gray, white and red. Archaeologists say that foxtail millet is so old that no wild plant of the species is known to exist today. Foxtail millet is known with several names in different parts of world and India (Table 1). Foxtail millet is thought to be native to China and is commonly cultivated in several regions of Africa, India, Russia, USA and Europe. It is an annual grass with erect and robust culms.

Amaranth crop stands in the group of pseudocereals and it is popular for its significant nutrient content as well as attractive inflorescence. The word Amaranthus came from a Greek word “Anthor” meaning eternal or unwilting. Amaranthus belongs to family of dicotyledonous plants Amaranthaceae and is one of the multipurpose rare plants whose leaves are consumed in the form 15 of vegetable while the grains are consumed as cereals. Amaranthus being an ancient crop has been included in the human diet since the pre-colonized South American civilizations.

Small size grains namely millets are produced by extraneous grasses and the word millet is derived from ‘‘mille’ a French word synonymous to thousand indicating handful of millet grains in a handful measure contains thousand grains (Taylor and Emmambux, 2008). Small millets and pseudo cereals belong to Gramineae family and were major ancient foods of Asian and African continents while Western countries used them as only bird feed.

During recent time, world agriculture is in search of sustainability in farming. However, it is tedious job for the developing countries because of poor input management and degradation of resources, ever-growing human population and increasing demand for food and livestock feed, and shrinkage of land and other natural resources.

Intercropping with food crops and vegetables is widely practiced by small and marginal farmers of the world mainly belonging to arid and semi-arid regions. Because of several benefits obtained, farmers prefer to adopt intercropping system. In temperate regions, mixed stands of cover crops and combinations of cereal and legumes forage production are very common.

Wheat (Triticum aestivum L.) is one of the major cereal consumed globally in various form as food. The powder of wheat flour is prepared by grinding of wheat seeds. Soft wheat flour has low gluten content that causes its crumbly texture. However, hard wheat flour has high gluten content of about 12-14% and has elastic toughness due to which it has good shape once its baked. Wheat flour is a basic ingredient in India’s famous flatbreads, and it can also be a key ingredient in addressing major health concerns in India.

Food processing sector in India has largest segment of bakery with more than 1.3 million tonnes of production from organized sector and 1.7 million tons from 1,000,000 unorganized sectors. India is second largest producer of biscuits globally. Our bakery industry is positioned third in generation of revenues among processed food sector.

Fungicide which is effective only if applied prior to fungal infection is called a protectant, eg. Zineb, Sulphur. Protectant fungicides are prophylactic in their behaviour.

Pyrethrum is the most widely used botanical insecticide. The active ingredient, pyrethrin, is extracted from a chrysanthemum plant, grown primarily in Kenya, Rwanda, Tanzania and Ecuador. Pyrethrum is the powdered, dried flower head of the pyrethrum daisy, Chrysanthemum cinerariaefolium.

Demand: Wants that are supported by a price at which they can be purchased are called demand. It is a relationship that, ceteris paribus, depicts the various quantities of a good that buyers would be able and willing to buy at various prices at a particular point in time.

Demand Schedule: It is a table that displays different quantities of a good that consumers would be willing and able to buy at different prices at a specific moment, ceterius paribus.

Demand curve: A demand schedule is a graph that displays the various quantities of a good that buyers would be able and willing to buy at various prices at a specific point in time, according to Ceterius peribus. It in turn fuels growth by increasing demand for industrial goods..

All of nature’s biodiversity is not visible. Biodiversity can also not be studied and/ or understood by looking at and analyzing it with the naked eye. A great proportion of the planet’s biodiversity flourishes in the ecosystems not directly accessible to us and the organisms in the sizes our eyes cannot record. The soil biodiversity is more interesting and more varied than we have understood and appreciated. The biodiversity in the soil - together with the physical environment - constitutes what we can call the pedosphere. Biodiversity in the pedosphere is distinguishable from that of the biodiversity above the soil surface. One is nonplussed by an understanding of some of the unbelievable features and functions of the pedosphere biodiversity.

The Convention on Biodiversity (CBD) held on the occasion of the historical Earth Summit in Rio de Janeiro in 1992 underlined the significance of biodiversity conservation for various tangible and non-tangible benefits as well as one of the key factors for sustainability. However, the conservation of soil biodiversity for realizing sustainability

Abstract

The natural color of foods is due primarily to carotenoids, anthocyanins, betanin and chlorophylls, either as inherent food constituents or as food or feed additives. These compounds have drawn considerable attention in recent years, not because of their coloring properties, but due to their potential health-promoting effects. Their occurrence and levels in foods, along with the factors that influence the composition, have been widely investigated. Processing effects have been actively studied. In spite of the intense search for plant and microbial sources and efforts to increase yield, few natural food color additives have reached the market. Developing new colors for the food industry is challenging, as colorants need to be compatible with a food flavors, safety, and nutritional value, and which ultimately have a minimal impact on the price of the product. In addition, food colorants should preferably be natural rather than synthetic compounds. Micro-organisms already produce industrially useful natural colorants such as carotenoids and anthocyanins. Microbial food colorants can be produced at scale at relatively low costs. This chapter highlights the significance of color in the food industry, why there is a need to shift to natural food colors compared to synthetic ones and how using microbial pigments as food colorants, instead of colors from other natural sources, is a preferable option.

Introduction

Citrus is the leading tree fruit crop in the world. In India, citrus ranks second in area, sharing 12.8% of the total area under fruit crops with a 9.6% share in production. In the citrus group, mandarins are the most important, occupying 50% of the total area under citrus, followed by sweet oranges and limes. “Limolin”: the glycoside which is responsible for the bitter taste of citrus fruit juice.

Abstract

Plants store structural carbohydrates (SCs) and Non-structural carbohydrates (NSCs) to buffer source–sink interactions at various phases of growth and under diverse environmental conditions. Structural carbohydrates (cellulose, lignin, hemicelluloses) provide structural integrity to the plant and the Nonstructural carbohydrates (sugars and starch) plays important role in growth, respiration, osmotic regulation, defence and helps in maintaining the carbon balance. Abiotic stresses such as drought, heat, salinity, and lodging etc. restrict the growth and development of plant which culminates into lower yield. Hence, the role of Non-structural carbohydrates needs to be elucidated for achieving desired crop improvement interventions to mitigate the harmful effects of climate change and having sturdy crop system. Improving our understanding of whole-plant sink–source dynamics and further optimising them will have far-reaching consequences in the near future.

Abstract

Global consumption of wheat during 2021/2022 marketing year reached to 787.4 million metric tons (https://www.statista.com/aboutus/our-researchcommitment/1239/m-shahbandeh). It shows about 4.4 million metric tons increase from the previous year. With the increase in population a significant increase in wheat production is needed to feed 9.7 billion mouths by 2050. A very limited effort can be directed to increase area under wheat production. Diseases and pests of wheat cause significant reduction (>30%) in production and 11-15% of total post-harvest losses of food grains were reported in India, which equates to about 20 million tonne (Basavaraja et al. 2007) and more than AUD10 million per year (Singh 2010). Thus, saving wheat from diseases can significantly contribute to the 2050 food security goal.

10.1 Land and Water Resource

India has got the world’s 2.45% area and 16.87% of population with only the 4% of available fresh water (Table 11.1). This indicates the necessity of development of water resources and optimal use of it. India at macro level does not have short of water. But the shortage of water is due if not properly managed by conservation and sector wise utilization.

The water resource potential of the country has been assessed by different agencies in different time (Table 11.1). It is observed that the latest estimate of 1869bcm (1993) are within the little variation of the estimates since 1954. The utilizable water resources of the country are assessed 1123bcm by CWC (1993) of which 690bcm from surface water and 433bcm from ground water sources. This 690bcm can be harnessed if matching storage structures are built. The surface water utilizable potential may increase by 220bcm if inter-basin transfer

Cartography has much back history than what we seen in portable form by its name or definition. Many prehistoric painting of caves had their own time frame record of maps, artifacts and design have been preserved hoping that they are sufficient to the era of forgotten habit and culture, and treasure explicit ancient world. The ancient wall painting of seventh millenium BC, might have indication of oldest maps in the world and the painting is assumed to be the location of ancient city Antolia as Mellaart, depicted 1967. Onward 600 BC, the modern form of cartography started to develop map. The pioneer contribution in map designing and development, old Greek and Roman were main contributor in this direction. One Greek Philoshopher Ptolemmy, multi-talented genius are recalled in this context, who later credited with first documented map of world during production of Geographica, is a treatise on cartography, very soon one Arabian Scholar Muhammad Al-Idrisi prepared a medieval Atlas involving knowledge of world collected by Arabic merchants in 1154.

Fundamentally toposheet represents a kind of map in which topographic features of particular area is given details on the map features in two dimensional land surfaces. It shows both horizontal and vertical portion of the terrain with a combination of contour lines, contours, symbols, labels and related representation together in one piece of paper. Toposheet portray the shapes, location of mountains, many natural and manmade features, and the toposheet combinedly uses for extracting accurate information about particular area containing land surface features.

The use of drones, or Unmanned Aerial Vehicles (UAVs), in the agriculture sector has ushered in a new era of precision farming. These versatile flying machines equipped with advanced sensors and cameras have the potential to transform various agricultural activities, resulting in increased productivity, reduced costs, and more sustainable practices.

This chapter explores the history of drones, their components and functioning, the numerous agriculture activities where drones can be employed, the benefits they offer, real-world use cases, challenges in adoption, and possible solutions to fully realize their potential in the agriculture sector.

India is known for its heritage and diaspora has 6,40,867 villages with a population of aprox 120 crore people which is about 66.46 % of the population. The villages in India have always remained neglected and never tried to market their products to urban consumers. But the rise in incomes of the Indian urban consumers and the increased awareness due to technological advancement it leads to the growth of the Indian consumer market which became attractive for the Indian as well as foreign companies. The efforts by Indian Government for rural products contributed to the development of rural products and their marketing. 

Soil, climate and water decide the nature of crop to be grown in a particular region. While soil and climate can be manipulated to certain extent, there is no substitute of water. Water is governed by the hydrological cycle. The major source of water is rainfall which has been reduced over the years due to climate change. The per capita water availability in India was 4944 m3 in 1955 which has been reduced to 1750 m³ now and is expected to come down to 1500 m³ by 2025.

Filtration may be defined as the separation of a mixture or solution into component parts. The resulting components may be pure or may be solutions or mixtures. In water/wastewater treatment filtration technique is used for removing suspended solids, dissolved solids and organic matter.

The number of people is expected to increase from 7.2 billion to 9.6 billion by 2050. (UN, 2013). This represents a 33% increase in population, but the demand for agricultural products will climb by approximately 70% during the same time period as the global quality of living rises (FAO, 2009). Livestock is essential for ensuring food security.

Biosensors are the next generation detection devices, use biological sensing elements like enzymes, nucleic acids, antibody, cells, organelles, tissues, receptors; have got varied applications in the field of drug discovery, diagnosis, biomedicine, food safety and processing, environmental monitoring, defense and security etc. Microbial biosensors are analytical device that uses naturally occurring or engineered microbial cells as the recognition elements to detect physiological changes in cells with the help of suitable physicochemical transducer.

The green pepper or chilli is reported to be the native of tropical America (Thompson and Kelly, 1957). This was widely cultivated in Central and South America in early times and was unknown in Europe prior to the discovery of America. The chilli belongs to the family Solanaceae and genus Capsicum. Only four species are under cultivation, out of which the cultivation of the two, Capsicum pendulum and Capsicum pubescens, are restricted to South and Central America.

Harald Ulrik Sverdrup (1888-1957), a Norwegian who began his career studying meteorology with Vilhelm Bjerknes in Oslo, was appointed director of Scripps Oceanographic Institution in 1936. His 1947 paper “Wind-driven currents in a baroclinic ocean”, which showed the link between meridional currents and the curl of the wind stress, began the modern era of dynamical oceanography and initiated large-scale modeling of ocean circulation.

Collections of blood To collect blood for different haematological analyses, an animal’s vein are punctured with a syringe and needle. Requirements • Hypodermic needle • Syringe • Collection vials or tubes containing anticoagulantsProcedure • The place of blood collection should always be cleaned with alcohol and hairs trimmed. • Press on the vein to raise it. • Free-flowing blood can be collected directly into the vial containing anticoagulant after the needle is inserted into the vein. • 5 ml of blood from large animals and 2.0 ml of blood from small animals like dogs and cats are sufficient for normal haematological investigations. • Rotational motions in the vials are used to mix the blood

Development of the country build is upon the aspect of the human measures. Imaginative, inventive, truthful and persevering persons head the nation in the virtuous path and guide to all aspects of growth in every field. Entrepreneurs drive nation’s growth. Entrepreneurs are familiar for their specific features Acknowledging this reality on growth of entrepreneurship. Entrepreneurship is an ingenious and imaginative reaction to the surrounding. The expression “entrepreneurs” normally mention to person who tackle recently developed capabilities that are imaginative and inventive. Analysis towards the entrepreneurial character has manifest that majority of the successful entrepreneurs share a defined category of personality features. This acquires the peculiarity as to. The existing analysis is an effort to inform the main features of entrepreneurs in food processing enterprises of Assam.

Introduction

Finance is vital to entrepreneurship. With limited resources starting a business is a challenge. Earlier generations of entrepreneurs establishing a business were different. They first guaranteed that money would be available to start—the business. So, if one wanted to build up a unit for a business, one would undertake market research and then approach the bank. Then activities like product development, ordering equipment, determining the site, acquiring land for the facility, what government policies are applicable etc., were considered. Before starting a business, an entrepreneur considers these factors. That was the old regime.

• substance or vegetable substance
• It is produced undermost hygienic conditions to produce/manufacture it, inferior or cheaper ingredients/raw materials are not used
• Food additives/processing aids used are permitted and are within prescribed limits.
• It is not misbranded

1.1 Introduction

Horticulture is defined as “The science and art of growing vegetables, fruits, flowers, ornamental plants and landscaping of gardens and surroundings in small and commercial gardens”. The Latin word “horticulture” comprises two parts: “hortus” (which means “garden”) and “cultura” (which means “cultivation”). In other words, horticulture is the nurturing of gardens. Pomology, olericulture, floriculture, and landscaping are the main aspects of horticulture. Horticulture is becoming more and more important since it produces greater output per unit of land and provides humans with nourishing food, improving their quality of life and enhancing the visual beauty of nature. Regarding the worth of the goods, one of the main branches of horticulture is vegetable growing.

Technically speaking, every component of a vegetable is edible. However, the phrase is typically used to refer to edible plants that include reserves of food in the form of roots, tubers, bulbs, stems, petioles, leaves, buds, flowers, fruits, and seeds that can be consumed either cooked or raw. Growing vegetables is crucial not only for supplying food that is protective but also for serving as a substantial auxiliary food that contributes more significantly to food consumption. They are vital parts of a balanced diet since they are nutrient-rich.

11.1 Introduction

The word Raphanus has been originated from Greek, meaning quick appearing, refers to its very rapid germination and growth characteristics. It is grown chiefly for its succulent and fleshy edible taproot eaten raw as salad or cooked. The leafy tops are very rich in vitamins A, B and C, and minerals particularly calcium and iron. Major sugar present in radish is glucose. It is a short duration crop and highly productive, so preferred as intercrop or in relay and sequential cropping.
