Introduction

Botanical name of cocoa is Theobroma cacao and family is Malvaceae. The cocoa bean, also cacao bean or simply cocoa or cacao, is the dried and fully fermented fatty seed of Theobroma cacao, from which cocoa solids and cocoa butter are extracted. Cocoa flavour is the most distinct feature of chocolate, thus cocoa beans are the basis of chocolate. Dried cocoa beans are usually processed into cocoa butter, which contains fat between 56% and 58%, made up of a mixture of triglycerides. Cocoa butter with this composition is good for making chocolate and has favourable hardness and a melting point of body temperature. Theobroma cacao originated from the Jungle of the Amazon in Brazil. Theobroma cacao consists of two subspecies: the Cacao, a subspecies known as the Criollo, which can be found in Central and South America, and spharocarpum, which is also called theForastero. The Criollo has superior and fine flavour. The pods are red and the beans have no color. Forastero has a green pod

Dried Cocoa Bean have chemical composition as: The shell (testa) represents 10-14% dry weight of the cocoa bean, while the kernel or cotyledon is made up of most of the remaining 86-90%. The cotyledon confers characteristic flavours and aromas of chocolate and is composed of two types of parenchyma storage cells.

Before processing, the quality ofbeans is evaluated for the following indicators:

1. Degree of fermentation
2. Moisture content (maximum 6%)
3. Number of defects
4. Number of broken beans
5. Bean count (number per 100 g)

The development of a recipe for chocolate should be based on three criteria:

(i) The intended market or use;

(ii) The limitation being placed on material and production costs;

(iii) The desired quality.

The amount of fat present in the chocolate will affect the flow properties, and fat content must therefore be varied according to the intended use.

Some point to remember while manufacturing chocolate:

1. To maintain proper viscosity if fat content is increased then sugar content should also be increased.
2. Milk chocolate requires lower fat content than dark chocolate.
3. Addition of emulsifier like commercial lecithin can save upto 5% of added cocoa butter.

Chocolate is almost unique as a food in that it is solid at normal room temperatures yet melts easily within the mouth. This is because the main fat in it, which is called cocoa butter, is essentially solid at temperatures below 25^oC when it holds all the solid sugar and cocoa particles together. This fat is, however, almost entirely liquid at body temperature, enabling the particles to flow past one another, so the chocolate becomes a smooth liquid when it is heated in the mouth. Chocolate also has a sweet taste that is attractive to most people.

The first known cocoa plantations were established by the Maya in the lowlands of south Yucatan about 600 AD. Cocoa trees were being grown by the Aztecs of Mexico and the Incas of Peru when the Europeans discovered central America. The beans were highly prized and used as money as well as to produce a drink known as chocolatl. The beans were roasted in earthenware pots and crushed between stones, sometimes using decorated heated tables and mill stones, similar to those illustrated in Figure 1.1.

The biofilm formation is usually assayed by using Congo Red Agar (CRA) plate test. According to a method developed by Freeman et al., (1989) the isolates are stored in nutrient agar slants and screened for biofilm formation ability using CRA plates. Biofilm forming strains are observed as dark black colonies while others as red colonies on the CRA plates. Recently, the concept of these biofims have changed with new imaging technologies, biochemical methods and molecular ecosystem biology tools. A biofilm structure can be observed in 3-D form to the nano-scale level (Neu and Lawrence, 2015). A lot of studies are being conducted on the physiology of the biofilm cells, the genotypic and phenotypic variation among the biofilm community, as well as the biofilm metabolome, proteome and transcriptome (Raes and Bork, 2008). This will help in the the development of efficient methods to control deleterious biofilms (clinical biofilms, food contaminants, biofouling on industrial equipment and on ship hulls) and to enhance and modulate beneficial ones

(A) Anatomy of Lens

The lens is anoptically clear, avascular, biconvex structure of crystalline appearance with an anterior surfaceless curved than the posterior surface, placed between the iris and the vitreous. It is suspended by the suspensory ligament of the lens which is attached to the ciliary body and equator of the lens.

The lens consists of a central nucleus surrounded by the lens fibres and anterior epithelium, encapsulated in an elastic lens capsule. The anterior surface of the lens is in contact with the posterior surface of the iris whereas posterior surface is in contact with the vitreous. As the adult lens does not have a blood supply, its metabolic needs are met by the aqueous humour. The lens is composed of 65% water, 35% protein with scant amounts of electrolytes. The proteins can besubdivided into soluble proteins,

Introduction

A microscope is an optical instrument consisting of a lens or a combination of lenses for making magnified images of minute objects. A simple microscope consists of a single lens of magnified glass held in a frame, usually adjustable and has a stand for holding the object and a mirror for reflecting the light. But a compound microscope consists of two lenses i.e., objective and eye piece respectively. A compound microscope gives much greater magnification than simple microscope. The compound microscope will be extensively used in this course in studying various morphological and staining characters of soil microorganisms.

Abstract

This chapter examines how agricultural credit is a vital input for all agricultural development programmes. Private moneylenders used to be the main source of agricultural credit. However, this source was insufficient, costly and oppressive. To overcome this, a multi-agency approach involving cooperatives, commercial banks and regional rural banks has been adopted to provide cheaper, timely and adequate credit to farmers.

Abstract

Many obstacles hinder agriculture credit in rural regions: insufficient funding, failure to reach vulnerable rural residents, especially marginal and small farmers, and lack of local focus in agriculture credit distribution. India adopted a “Social and Development Banking” policy after nationalizing commercial banks in 1969. This policy aimed to solve some of these issues and boost the supply of formal credit to the agriculture sector. Rural communities would benefit from more loans at competitive interest rates due to this policy. In the 2000s, agriculture credit grew annually by 17.6%, much higher than the 2.6% growth rate in the 1990s. The increase in agriculture credit had three distinct features: indirect financing, a sharp rise in loans of Rs. 10 crore and above, and growing availability of agriculture credit through urban bank branches. The revival of agriculture lending in the 2000s mostly benefited small farmers and marginal farmers

Milk yield is one of the most important economic traits and modelling the lactation curve is important with respect to the unique shape with ascending, persistent and descending phases. The non-linear relationship of daily milk yield with days in milk has led to extensive research in modelling the lactation curve. The nature of the lactation curve, different models, identifying the best model of fit, factors affecting the curve parameters and orthogonal polynomials to model the curve are discussed in this chapter.

Current scenario of Startups in India

India, currently is being evolved as a hub for Revolution, innovation and Startups as it holds 3^rd rank in global startup ecosystem worldwide after US and China. The flagship initiative of Government, Startup India, is intended to construct arobust eco-system for fostering innovations and startups in the country. Through this initiative, the Government aims to empower the growth of startups through new innovations and strategies. As per the reports of Startup India, the startup sector is expected to mark steady annual growth of 12-15% (startupindia.gov.in). By the year 2018, India already had a list of about 50,000 startups. As per the data, more than 800 technology startups are being established every year (NASSCOM, 2015). The annual growth has increased to 15% and the number of female entrepreneurs has also increased to 14% (startupindia.gov.in). As of December 2021, the country is home to 81 unicorns which has a total estimate of $ 274.17 Bn. Out of these unicorns, 44 unicorns came into existence in 2021 itself, which was a record year for the country. These Figures show that startups have exploded in the country in recent years.

Artificial intelligence is a computational science concerned with smart computer machines capable of performing tasks similar to the human intelligence. The term AI is widely used for the projects involved in the developing the intellectual processes of human intelligence such as reasoning ability, meaning discovery, generalization, learning from the past. AI technology mainly analyses the huge amount of data based on the set of instructions or commands known as algorithms to do a specific function or task. The mathematician Alan Turing with a simple question “Can machines think?” revolutionised the history. His paper “Computing Machinery and Intelligence” in 1950 and Turing test has favour the development of goal and the vision of AI.

The research in AI are mainly focussed on the following intelligence components namely:

1. Learning
2. Reasoning
3. Problem solving
4. Perception
5. Language use

Entrepreneurship involves seeking and exploiting opportunities available for the benefit of the society. The changing agro-economic conditions in our country have offered a prospective context for developing entrepreneurship in agri-business in the country. Agri-entrepreneurship has the prospect of social and economic development, for example, employment generation, poverty reduction, improvements in nutrition, health and overall food security in the national economy especially in rural areas. The task of promoting entrepreneurship was earlier given to different departments and government agencies. In 2014, the Prime Minister decided to dedicate an entire ministry to build this sector as he felt that skill development required greater push from the government’s side. The idea is to reach maximum people and startups through funding and skill development initiatives.

Entrepreneurship plays a vital role in driving economic growth, and its significance in the agriculture and allied industry cannot be overlooked. As the backbone of many economies, agriculture and its allied sectors provide employment to a significant portion of the global population. We shall highlight the benefits of being an entrepreneur in this sector, discuss the different types of entrepreneurs, provide relevant statistics and case studies, and touch upon the factors affecting entrepreneurial behaviour. Additionally, we will examine the current trends and forecast for the next three years in the agricultural entrepreneurship landscape and examine relevant statistics and case studies and shed light on the government’s role in promoting entrepreneurship in the Indian startup ecosystem.

Following are the reasons why must understand topic indepth.

1. Agritech startups have raised over $1 billion in funding in the past 5 years.
2. The Indian agritech market is expected to reach $15 billion by 2025.
3. There are over 1,000 agritech startups in India.
4. The top three agritech sectors in India are precision agriculture, farm management, and farm equipment rental.

Abstract

This chapter explores farm budgeting, a method of evaluating plans for the allocation of agricultural resources at the decision-maker’s level. It involves estimating the income, costs, and profit of different farm activities.

Abstract

The waste utilization as derivative from different food processing sector has been emerged as the main challengeable problem around the world due to the generation of by-products at large quantities consisting seeds, peels, rags, unused flesh, bran, husk, germ, stalk etc. during various processing chain steps. Though these food by-products are potentially rich source of natural compounds which finds its wide utilization in different industries as affordable, cost-effective, novel ingredient comprising dietary fiber, phytochemicals, antioxidants, pectin, enzymes, organic acids, food additives, essential oils etc. subsequently after extractions, purified fractionation and fermentations methods. These food byproducts also have pharmaceutical and nutraceutical activity. A nutraceutical is like a medicine or food grade product, which not only provides physical benefits and nutritional supplements but also protects against various chronic diseases. This food processing waste utilization should be a topic of interest, by means of two ways, i.e., through waste quantity reduction and increased value-added food products production and also as renewable energy source. The purpose of this study is to highlight the opportunities to utilize food by-products from various food processing industries and to encourage the vital exploitation of the by-products containing large number of bio-active compounds having nutraceutical potential.

Fruit crops are mostly composite plants consisting of scion and rootstock, except banana, papaya, and strawberry. Rootstock exhibits a great influence on the performance of a scion in terms of production efficiency, yields, quality, adoptability, and resistance against biotic and abiotic stresses. The primary function of a rootstock is to provide anchorage or support to the scion by growing deep into the soil and also regulating the uptake of moisture and nutrients. The rootstock cannot be changed during the life-time of a plant, so it makes it inevitable to pay more focused attention to it because its functions are long-term and complex.

Introduction

Aonla or Indian gooseberry (Emblica officinalis Gaertn. Syn. Phyllanthus emblica) is one of the important indigenous fruits of the Indian subcontinent. Most of the xerophytes are members of the Euphorbiaceae.

The tropics are evergreen, while the subtropics are deciduous. The highest concentration of vitamin C in aonla is found in mature fruit rather than immature fruit. The special attribute is its capacity to retain vitamin C even in a dried stage, which is not possible in other fruits.

Aonla contains six seeds per fruit, and in it is found zygotic dormancy. Flowers are borne in the axils of the leaves on determinate shoots.

Maharashtra is the leading state in India for pomegranate cultivation: Maharashtra. NRC of Pomegranate, Kesaon, Solapur, Maharashtra: Established in 2005. Because of the presence of anthocyanin, the aril and skin have a red color. Dried seeds with pulp are known as ‘Anardana’: It is widely used as a condiment, prepared from a sour type of wild pomegranate is called as Daru. Commonly found in the Himalayan region, has a long productive cycle and is resistant to bacterial blight. Double flower type ornamental plant in it modification of stamens into petals makes them look like rose flowers. Nana or dwarf type is called Bonsai pomegranate, exclusively used for ornamental purposes.

Introduction

Cherries occupy an important position among temperate fruits all over the world. Cultivated cherries are divided into two main groups, i.e., sweet cherries (Prunus avium) and sour cherries (P. cerasus). Cherries are rich in protein, sugar, potassium, calcium, iron and zinc. Sweet cherries are believed to have originated in an area between the Black and Caspian Seas in Southern Europe. The earliest records indicate that it was first domesticated in Greece around 300 BC. It spread to Italy from Greece where it was established as a fruit crop by 37 BC. Early setter’s brought seeds to North America and parts of South America. In India, it was introduced by British setter’s in Kashmir, Kullu and Shimla hills during the pre-independence era. World leading breeding of cherry: John Innes Horticultural Institution, Merton. A putative ancestor of cultivated sweet cherries: Anthocynins (antioxidants) are the red pigment found in cherries.

Introduction

Coffee is the second important beverage, ranking second among traded commodities. Its dried beans are roasted, ground, and brewed to make a stimulating and refreshing beverage. Arabica coffee originated in Ethiopia, from a place called Caffa. The word “coffee” is derived from a place called “Caffa.” Here it occurs naturally in the forest between 1,400 to 1,800 feet of elevation. Nearly 80 percent of the world’s coffee is produced by Coffea Arabica. Robusta coffee is thought to have originated in Central Africa (Congo and Zaire). Arabica coffee was introduced in 1670 by Muslim pilgrim Baba Budan. He brought seven seeds from Yemen and cultivated them in Chikmagalur, Karnataka. The original seeds he brought were probably Mokka seeds. Robusta coffee was introduced from the Indochina region at the close of the 19^th century for planting in the states of lower elevations. World: Brazil, Vietnam, Colombia, Indonesia, India, Ethiopia, Peru, Mexico, Guatemala and Honduras. It is also growing in India in Karnataka, Kerala, Tamil Nadu, Andhra Pradesh and Orissa.

Introduction

Tea is the most popular and cheapest beverage consumed by two-thirds of the world population. The stimulative effect of tea is due to the presence of caffeine (1.25–4.5 %). Panthothenic acid, caffeine and theophylline present in tea stimulate the nerves and are good for the heart. Tea is grown in 50 countries, predominantly in Asia, Africa and Europe. Of the major tea producers, India, China, Sri Lanka, Kenya, Russia and Indonesia contribute the maximum share to global production. Though the share of India in global tea production has declined over the years, it still retains its status as the largest tea producer with 30 % of world output (2,780 million kg). India can also boast of producing many varieties of tea. Well-known varieties like Darjeeling, Assam and Nilgiris are well-known for their distinctive characters. Assam (24.86 %), West Bengal (15.20 %), Tamil Nadu (6.28 %) and Kerala (2.28 %) are major tea producing states in the country.

In agro-ecosystem, many agricultural and horticultural crops are dependent on insects for their pollination; their degree of interdependence varies species to species. Some plant species depend primarily on a single pollinator’s species or genus, whereas some plant species accept diverse pollinators. About to 80 per cent of flowering plants’ pollination determined for pollinators (FA0, 2007) and out of that most of the floras depend on insect pollinators for pollination and pollinators depend on flora for their food. Bees are considered as most important pollinator due to their diversity, credential ability and effective pollinators of many plant species. Most of the crops pollination need was met by wild pollinators living within the farming landscape (Kevan and Phillips, 2001). Therefore, pollinators play paramount role in ecosystem through enhance the crop productivity and conserving biodiversity. On the above service of pollinators is priceless and natural endowment, but the society we live in, always categorized and measured in terms of financial value. In 2005, globally, insect pollination services economic value was estimated to be about €153 billion (Gallai et al., 2009). The United Nations also reported that the economics of ecosystems and biodiversity by insect pollination was valued at £134 billion. The assisted pollination may have to be done when natural pollination is insufficient in order to reduce potential yield loss (Klein et al., 2007).

Introduction

Animal behaviour is the study of how animals interact with one another, other living things, and their environment. Animals display a variety of behaviours in response to both external stimulus and their own pathophysiological state. Almost all domestic animals express a variety of behavioural responses throughout their lifespan, like feeding, sexual behaviours, etc. But every species responds to the same stimuli in a different way. This is why; the study of animal behaviour helps in efficient breeding, feeding, and reproductive management. It also serves as a reliable indicator of overall health and well-being.

5.1. Introduction

The energy equivalent can be considered to be an alternate energy unit, precisely related to units such as the joule, calorie, or Btu. In energy talks, many units are employed. They are divided into two categories: (a) basic units and (b) source-based units.

Preparation of base map being in mind, the forest, agriculture, water, road and boundary are almost same for all but theme may be different as per requirement. Base information is to survey and need terrain information, the preparation includes land forms by separation of water, kart area, coastal area. Meanwhile preparation of focus might be on DEM (Digital Elevation Model) and water movement helps in demarcation of boundaries on map.

Aerial photography is objective of getting panoramic view of earth surface to analyze the features of earth and their interrelation at particular time period which may be changed in further events. In this concerned, the observation may play a vital role in achieving the goals of photography. Undoubtedly it is widely used in social function and so on, but still awaited for scientific or research use. Drone can measure the geometry of ground surface at lower altitude with more accuracy in the form of visual feature in natural colour. flight height of drone mainly limits the large area coverage due to lower flying and drone can work perfectly at low altitude planning with good quality feature/photography.

Conservation Agriculture Conservation agriculture is an approach to managing agro-ecosystems, for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. It is a set of technologies, including minimum disturbance, permanent soil cover, diversified crop rotations, and integrated weed management (Reicosky and Saxena, 2007; Hobbs et al., 2008, Friedrich et al., 2012).

Agriculture is a fundamental human activity that depends intrinsically on natural processes, including soil fertility, water recycling, and pollination, and both nature and agriculture are increasingly suffering the negative impacts of climate change (EEA, 2019). At the same time, unsustainable agriculture also poses a major threat to biodiversity (Secretariat of the Convention on Biological Diversity, 2014), negatively affects the state of our soil and water, and is an important contributor to climate change (Jia et al., 2019).

The oxygen content may be measured either chemically or electronically. The normal chemical method is the so-called Winkler method which is a titration method, consisting of adding certain chemicals to the water and observing a colour change which will be directly related to the oxygen concentration.

India has an enormous wealth of cattle, which is crucial to the development of the socioeconomic status of millions of rural households as well as the country’s economy. In addition to giving millions of people access to lowcost nutritious food, this industry plays a significant role in boosting family incomes and creating gainful employment in rural areas, notably among landless laborers, small and marginal farmers, and women.

Dairy farmers hope to have better milking cows than those in their current herds. A solid foundation is necessary for every farming operation. Undoubtedly, the dairy farm documentation system is among the most important facets of farm management. Tracking each cow’s productivity within a herd and assisting breed development generally are the major objectives of a dairy farm tracking system. This information could be referred to as production data.

The Indian economy, which meets its own dairy demands, has reached a turning point with its bovine breeding initiatives. The viability of this enterprise, however, depends largely on completing as many successful artificial insemination cycles at a cattle farm. Estrus behaviour observation is used to determine when artificial insemination should take place. But since not all cattle exhibit substantial estrus symptoms, insemination results are not always reliable. An estrus detecting instrument known as an Electronic Nose (eNose) is created to address these issues.

There are 8 fundamental Ergonomic Principles for better work performance which help you identify ergonomic risk factors and maintain your stellar safety record.
• Maintain neutral posture
• Work in power zone
• Allow for movement and stretching
• Reduce excessive force
• Reduce excessive motion
• Minimize contact stress
• Reduce excessive vibration
• Provide adequate lighting

Anthropometry is the study of the measurement of the human body in terms of the dimensions of bone, muscle, and adipose (fat) tissue. It is a branch of anthropology dealing with measurements of human body to determine difference in groups and individuals. The word “anthropometry” is derived from the Greek word “anthropo” meaning “human” and the Greek word “metron” meaning “measure” (Ulajaszek, 1994).

The level of motivation of an individual has a definite relation to the fatigue experienced while doing any work. When a person dislikes a task, motivation to do is low and fatigue sets in faster. Interest in job produces high motivation and prevents fatigue. Besides the way of carrying a task is of great concern if we want to maintain our right posture, in order that we do not have to face any musculoskeletal disorders.

The domestic electric food juicer/mixer/grinder has become an integral fixture in the typical modern kitchen. Generally functional as liquidizers, grinders and juicers, this paraphernalia comes in handy for grinding/pulverizing/powdering dry foodstuffs either raw or roasted (cereals, grains, masalas, coffee seeds, etc.), for mixing liquids and for converting food— with or without the presence of water (or vegetable oils)—into forms of slurry or pulps. It is also used for extracting juice from fruits or vegetables.

Electric Cooking Range is also known as an electric stove or electric range; is a stove with a built-in cooktop and with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solidfuel (wood or coal) stoves which required more labor to operate and maintain. “Cookstoves” (also called “cooking stoves” or “wood stoves”) are heated by burning wood or charcoal; “gas stoves” are heated by gas; and “electric stoves” by electricity. Unlike gas stoves, electric stove tops don’t produce a flame.

Drivers
• Unique aspects of the local climate and soil.
• Availability of resources and land labor.
• The current level of resource use.
• Economics of the proposed integrated farming.
• Farmer’s management skills

The exploration of facts about healthy and nutritious food has increased over the years. The advent of advance scientific tools has elucidated facts regarding the role of diet or nutrients in regulating gene expression (Sales et al., 2014). Various studies based on molecular interactions in food has revealed that many dietary components such as proteins, carbohydrates, fats, minerals, vitamins and phyto-constituents has the tendency to regulate gene expression.

Coriander, Coriandrum sativum L. is an erect annual herb belongs to the family Apiaceae. Coriander may also be referred to as Cilantro, Chinese parsley or Dhania. In India it is cultivated in Rajasthan, Gujarat, Madhya Pradesh, Tamil Nadu, West Bengal, Uttar Pradesh etc. The leaves of the plant are variable in shape, broadly lobed at the base of the plant. Leaves are slender and feathery higher on the flowering stems.

Leavening agents produce carbon dioxide which helps to give characteristic structure to bread cakes and biscuits etc. In the case of cakes, leavening is produced by air entrapped in the dough due to the presence of egg in the mix. The important groups of leavening agent’s are l. baker’s yeast 2. Chemical leavening agents

Procedure: weigh vegetables 20 g (for each variation) Water: add sufficiently
1. Cook the vegetable in water in a pan according to the “cooking time” variations given in the table 1 and note down the color, texture and flavor changes takes place during cooking for each variation and record the observations
