1. INTRODUCTION

Colour affects every moments of our lives, strongly influencing the cloths we wear, the furnishing in our house and garden, and the appeal of foods. Not only this, colour aids the recognition of food and also has psychological appeal on the enjoyment of food. It is also one of the first characteristic perceived by our senses and help in determining acceptability, judging the quality and basic aesthetic value of food. Addition of colour to the food ensures the uniformity and intensifies the naturally occurring pigments in our food. To achieve this, historically natural or bio-colours have been used extensively till the end of 19^th century, when synthetic colours called ‘coal tar dyes’ were developed that acquired a widespread acceptability. But unfortunately, these are not totally safe for human consumption; for example high levels of erythrosine intake causes thyroid tumors, while Ponceau 4R, tartrazine and sunset yellow were found to be allergic. Many dyes used as colourant have been proved to be carcinogenic. The consumer wants to see the food looking natural as the synthetic colours have been proved to be carcinogenic to humans. Thus, increasing consumer awareness for natural products with almost no chemical additive and certified dyes (which was earlier considered safe) has necessitated the need to exploit food colourants of natural origin. Natural colours are generally extracted from materials of biological origin like fruits, vegetables, seeds, roots and microorganisms, and are often called as ‘Biocolours’. Microorganisms like Rhodotorula, Sarcina, Chromobacter have been proved to be a good source of biocolour.Colour has also been successfully produced from microorganisms using apple pomace as a base for the growth medium of biocolour producing microorganisms.

1. INTRODUCTION

Marketing is a general term used to describe the activities that lead to the sale of your product. It is the process of planning and executing pricing, promotion and distribution programs to satisfy customer needs. It involves collecting information, analyzing alternative market outlets, developing different product forms, pricing products to compete in the marketplace, defining the scope of the proposed market area and meeting consumers’ needs. So marketing is more than just selling a product or service. It is an essential part of any business. Without a good marketing program, even the best businesses fails.

Value-added agricultural groups typically don’t pay enough attention to marketing. Selling agricultural commodities usually only involves hauling the commodities to a market where there is usually a willing buyer. So farmers often spend their time analyzing brick and mortar issues associated with processing and manufacturing (making the product rather than marketing the product). Often the attitude is that, if we make the product, someone will come along and buy it. So value-added agricultural businesses consistently fail because they do not understand the importance of designing and implementing a good marketing program.

As a first step, ‘A Marketing Primer and Marketing Basics’ will help you with a basic understanding of marketing. Successful marketing involves designing and implementing a marketing strategy for your product. Marketing Strategies provide generic strategies for various types of products and product buyers. In a simple term, marketing activities and strategies result in making products available that satisfy customers while making profits for the companies that offer those products.

7.1 Introduction

Garden designing is an important and crucial step as whole aesthetic view of the garden depends upon it. A beautifully designed garden can attract plenty of viewers as well as fauna while a poorly designed garden can destroy the view of the garden as a whole. So, while designing a garden all the basic principles and elements of gardening should be kept in mind.

7.2 Steps in Preparation of Garden Design

Site identification

Generally, the site for garden development is provided by the client itself. So, in this case we should go for site analysis step directly. Site identification is always a choice of client/human. If landscape architect has liberty to identify a land for garden establishment, he should identify the site as per choice of the client, usage and special considerations of the client.

1.1. Plant Quarantine

The literary meaning of the word quarantine is” a state, period or place of isolation in which the people or animals or plants or acquacultures that have arrived from elsewhere or been exposed to infectious or contagious disease are placed.

Plant quarantine is a technique of keeping the imported or introduced plants or planting material in isolation for detecting the exotic pests, diseases and disease pathogens and weeds which may be harmful to the importing country for its crop plants, agriculture or the ecosystem. These plants/planting material are kept in isolation for a specified period which differ from plant species to plant species depending on the type of pathogen/pests for which the material has to be quarantine. This is based on the Rules and regulations promulgated by governments to regulate the introduction of plants, planting materials, plant products, soil, living organisms, etc. with a view to prevent inadvertent introduction of exotic pests, weeds and pathogens harmful to the agriculture or the environment of a country/region, and if introduced, to prevent their establishment and further spread. Plant quarantine is thus designed as a safeguard against harmful pest /pathogens exotic to a country or a region.

Plant quarantine is a most important activity in the introduction of plants and planting material as various insects, including mites and nematodes and diseases caused by fungi, bacteria, viruses, viroids, phytoplasmas,rickettsialike organisms are known to attack various crops of economic importance to not only reduce the quantity but also spoil the quality of the produce to a considerable extent and if these pests and pathogens are introduced with the planting material in its non ecosystem areas may prove fatal to the agriculture or ecosystem

In Article IX of IPPC, it is stated that RPPOs shall

• Function as coordinating bodies in the areas covered by the IPPC (including information sharing)
• Cooperate with the IPPC Secretariat in achieving the objectives of the IPPC (including the development of ISPMs)
• Cooperate with other RPPOs and participate in the regular Technical Consultations for RPPOs that are convened by the IPPC Secretariat

At present, there are 10 RPPOs covering the different regions of the world. Each RPPO has its own independent statutes and conducts its own regional cooperation programme. RPPOs produce regional standards for their members. They cooperate with each other and with the IPPC Secretariat. In particular, they meet in Technical Consultations to promote the development and use of relevant ISPMs and to encourage inter-regional cooperation on phytosanitary measures for controlling quarantine pests and preventing their introduction and spread.

Molecular biology is a branch of science that deals with understanding the biological activities at the molecular level. Molecular biologists are involved in understanding the concepts behind various intra and intercellular interaction of molecules, contributing to the knowledge about interrelationship of DNA, RNA and protein synthesis, i.e., how genes are transcribed into RNAs and how RNA is translated into protein, the phenomenon which is commonly known as “Central Dogma”stated by Francis Crick in 1956.

“The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred back from protein to either protein or nucleic acid”-Francis Crick.

A model is something that mimics the behavior of some real system of interest. Our interest here will be in water quality models, which are usually equations, and which predict some result based on factors that influence that result. A water quality model is a representation of a real system. The essence of a good water quality model is that it is simple in design and exhibits the basic properties of the real system that we are attempting to understand. The model should be testable against empirical data. The comparisons of the model to the real system should ideally lead to improved mathematical models. The model may suggest improved experiments to highlight a particular aspect of the problem, which in turn may improve the collection of data. Thus, modeling itself is an evolutionary process, which continues toward learning more about certain processes rather than finding an absolute reality.

Water pollution is a large set of adverse effects upon water bodies such as lakes, rivers, oceans, groundwater caused by human activities. Although natural phenomena such as volcanoes, storms, earthquakes etc. also cause major changes in water quality and the ecological status of water while these are not deemed to be pollution. Water pollution has many causes and characteristics. Increases in nutrient loading may lead to eutrophication. Organic wastes such as domestic sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole ecosystem. Industrial discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids. Discharges can also have thermal effects, especially those from thermal and nuclear power stations, and these too reduce the available oxygen. Siltbearing runoff from many activities including construction sites, forestry and farms can inhibit the penetration of sunlight through the water column restricting photosynthesis and causing blanketing of the lake or river bed which in turns damages the ecosystems the process is called as eutrophication.

Pollutants in water include a wide spectrum of chemicals, pathogens, and physical chemistry or sensory changes. Many of the chemical substances are toxic or even carcinogenic. Pathogens can obviously produce waterborne diseases in either human or animal hosts. Alteration of water’s physical chemistry include acidity, conductivity, temperature, and excessive nutrient loading. Even many of the municipal water supplies in developing countries can present health risks leads to many diseases.

2.1 Historical Development

We have seen in Chapter 1 that modeling is about establishing cause effect relationship. Perhaps one of the earliest attempts in this direction is made as early as 1848 in Germany where it was tried to establish a relation between purity and pollution to the occurrence of certain biological organism. But as far as water quality modeling is concerned the first major breakthrough in this direction is the effort of Streetor and Phelps (1925) in oxygen sag curve. They developed model for estimating DO and BOD in Ohio River. The work of O’Conner (1962) for bacteria models are major milestone in pre-computer era modeling.

With the advent of computer during 1960s complicated kinetics and time variable simulation came into being. Most of the workers presented their efforts in terms of linear programming based water management models concerning waste discharge. Thomann(1963) has formulated linear programming based models for dissolved oxygen in an estuary. So a stage is set for study of eutrophication through modeling, but the problem is determination of values of various parameters in these equations.

During 1970s models expanded in terms of complexities mainly because of enhanced computational facilities. Two dimensional and dynamic framework has started replacing one dimensional steady state configurations. In the same year, Di Toro presented an analysis of the steady state two dimensional concentration distribution that results in the horizontal plane from the continuous discharge of a non-conservative substances (DO and BOD) into an infinite body of water.

10.1 Introduction

Biochemical Oxygen Demand (BOD) is a chemical procedure for determining how fast biological organisms use up oxygen in a body of water. It is usually performed over a 5 day period at 20 C. It is used in water quality management and assessment, ecology and environmental science. BOD is not an accurate quantitative test, although it could be considered as an indication of the quality of a water source.

10.2 Typical BOD values

Most pristine rivers will have a 5-day BOD of less than 1 mg/l. Moderately polluted rivers may have a BOD value in the range of 2 to 8 mg/l. Municipal sewage that is efficiently treated by a three stage process would have a value of about 20 mg/l. Untreated sewage varies, but averages around 600 mg/l in India and as low as 200 mg/l in the U.S., or where there is severe groundwater or surface water infiltration. Slurry from dairy farms is around 8000 mg/l and silage liquor around 60000 mg/l.

11.1 Introduction

Salinity is the saltiness or dissolved salt content of a body of water. The technical term for saltiness in the ocean is halinity, from the fact that halides, chloride specifically are the most abundant anions in the mix of dissolved elements. In oceanography, it has been traditional to express halinity not as percent, but as parts per thousand (ppt ), which is approximately grams of salt per liter of solution. In other disciplines chemical analyses of solutions, and thus salinity is frequently reported in mg/L or ppm (parts per million). Prior to 1978, salinity or halinity was expressed as % usually based on the electrical conductivity ratio of the sample to “Copenhagen water”, an artificial sea water manufactured to serve as a world “standard”(Lewis, E.L 1980). In 1978, oceanographers redefined salinity in Practical Salinity Units (psu): the conductivity ratio of a sea water sample to a standard KCl solution (UNESCO, 1981a) (UNESCO, 1981b). Ratios have no units, so it is not the case that 35 psu exactly equals 35 grams of salt per litre of solution (UNESCO, 1985).

These seemingly esoteric approaches to measuring and reporting salt concentrations may appear to obscure their practical use; but it must be remembered that salinity is the sum weight of many different elements within a given volume of water. It has always been the case that to get a precise salinity as a concentration and convert this to an amount of substance required knowing much more about the sample and the measurement than just the weight of the solids upon evaporation. For example, volume is influenced by water temperature; and the composition of the salts is not a constant. Saline waters from inland seas can have a composition that differs from that of the ocean. For the latter reason, these waters are termed saline as differentiated from ocean waters, where the term haline applies.

15.1 Introduction

A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, landslides, large meteorite impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating. The term tsunami comes from the Japanese words meaning harbor (“tsu”,) and wave (“nami”,). The term is created by fishermen who returned to port to find the area surrounding their harbor devastated, although they had not been aware of any wave in the open water. Tsunamis are common throughout Japanese history; approximately 195 events in Japan have been recorded.

A tsunami has a much smaller amplitude offshore, and a very long wavelength (often hundreds of kilometers long), which is why they generally pass unnoticed at sea, forming only a passing “hump” in the ocean (Fig. 15.1). Tsunami have been historically referred to as tidal waves because as they approach land, they take on the characteristics of a violent onrushing tide rather than the sort of cresting waves that are formed by wind action upon the ocean (Iwan, W.D., 2006).

1. Emergence and history of the concept of gender in development

In a chronological point of view it was the period of late 1960s to mid1970s that marked a turning point in development that saw the emergence of gender as an issue of concern. It was during this period that many important publications on psychology of women and gender roles started its manifestation. However, the recurring theme in most of these publications focussed the white male bias in research and research interpretation. Yet, these research publications served as a platform for a thorough discussion of the biological and social factors that contributed to the understanding of psychology of women. The book entitled, The Development of Sex Differences, edited by Maccoby (1966), can be seen as a pivotal moment in the field of gender psychology. The book with several chapters that lay the foundations of children’s gender development focused on theories of gender development. The publication of the book Man and Women, Boy and Girl in the 1970s put forth an advanced theory about gender identity and suggested that social factors played a more significant role in gender identity and gender roles. This sparked the debate of nature - nurture issues which are still significant to this very date. It’s during the same decade that scholars started to challenge the conceptualisations of masculinity and femininity and migrate from the unidimensional simplistic models of bipolar opposites.

Contributions of Carl Gustav Jung (originally Karl Gustav Jung) also had a great role in this migration. Carl Jung’s school of analytical psychology, proposed the concepts of anima and animus. These were part of his theory called collective unconscious which suggests that every woman has an unconscious masculine realm known as animus and every man has an unconscious feminine side known as anima. He postulated that this personal unconscious symbolized prototypical masculine or feminine principles and not an aggregate of either father or mother. It had the potential to transcend to the personal psyche and influence the behavior.

1. Introduction

For a proper understanding and analysis of women’s position in India’s rural economy, we require adequate and good quality data. This chapter examines the limitations of gender-disaggregated data on the rural economy of India with respect to three aspects: the ownership of land and other assets, participation in the rural workforce, and women’s share of agricultural incomes and earnings. In approaching the need for better data on gender, the following features of gender statistics as identified by UN organisations should be kept in mind (Corner undated)

1. Introduction

Gender equality in agriculture is a long time demand to achieve the sustainable agricultural development goals. According to the World Bank (2009) differences in the socially constructed gender roles and gender relations affect agricultural development as it creates inequality in the distribution, access to and control over agricultural resources between men and women; that in turn affect the agricultural development outcomes. However, role of men and women in agriculture is not constant across the world due to the disparities existing in the allocation of productive farm resources to women and men among different societies and cultures. Most of the agrarian social systems recognize men as the key players of crop production due to their ownership over agricultural land and other resources. This often masks the significance of activities carried out by farm women in the crop production process. Currently agriculture provides employment to nearly 27.2 percent men and 25.4 percent women globally (World Bank, 2020). Irrespective of the unequal power relations between men and women, their relative representation in the agriculture workforce remained almost equal throughout the years. Hence, it became inevitable to address the concerns of both genders in agriculture rather than concentrating only on women centric issues while formulating programmes and policies aiming agricultural development. These trends in agriculture motivated social researchers like Safiliou (1990) to propose gender as a ‘variable’ similar to ‘social class’ to rationalize agriculture. Globally, gender based researches has covered various dimensions of contributions of men and women in agriculture as cultivators as well as agricultural labours in different time period. However, studies on topics related to women’s rights, women empowerment, and gender equality in order to achieve food security and agricultural development has increasingly been carried out after the “fourth world conference on women: action for equity, development

and peace” held at Beijing (China) during 4-15 September, 1995. Though gender research in agriculture mostly revolves around farm women and their empowerment concepts like marketing extension, market-led extension etc., it has led to the empowerment of both women and men cultivators.

The chapter discusses the concept of gender in research and development, its evolution and its integration into research perspectives in agriculture. A brief description of gender analysis tools is also included.

1. Introduction

“Earth provides enough to satisfy every man’s needs, but not every man’s greed”

Mahatma Gandhi

Natural resources form the core of ecology that is put to economic use. It is usually defined in terms of materials created in nature that are used to satisfy human needs. Soil, water and energy supplies (eg. coal, natural gas) that serve to satisfy human needs and wants comprise the major natural resources (Barsch and Burger, 1996). Based on the impact on an environment, cost of extraction and rate of exhaustion, natural resources are broadly categorized into renewable and non-renewable resources. Major renewable sources comprise of wind, solar energy, tidal energy, geothermal energy, forest etc. which have the potential to be renewed or replaced through natural processes over time, once consumed. Unlike this, nonrenewable resources such as coal, petroleum, natural gas and similar types have finite reserves that cannot be regained once consumed. However, environmental degradation, aggravated by the growing population and climate change vagaries, has intensified the competition for these scarce resources in recent years. This has necessitated sustainable natural resource management strategies and advanced experimentations to convert nonrenewable energy sources to renewable forms as they form the basis of all present day development and economic growth. Increasing demands on natural resources have warranted a more prudent and diligent efforts in ensuring sustainable natural resource management. The dichotomy of unlimited human wants and limited resource availability is at the heart of all natural resource management principles that guide economics of resource allocation and optimum utilization.

1. Introduction

The intricate relationship between agriculture and women has been widely featured in the development discourse for long. Globally, more than 400 million women are engaged in farm work directly or indirectly. In other words, 42 per cent of economically active women are engaged in agriculture and they comprise about 43 per cent of the total workforce in agriculture (Dash and Srinath, 2013). In India, agriculture and allied sectors continue to be the most immediate avenues of employment and income for about 160 million rural women who work as farmers, co-farmers, farm labourers and farm entrepreneurs (Oxfam 2017; Sadangi et al., 2009). It is estimated that about 65 per cent of rural women workers are engaged in agriculture as cultivators and agricultural labourers in the country as opposed to 49.8 per cent of male workers. In these capacities, women perform multiple tasks such as land preparation, sowing, transplantation, harvesting and rearing of animals. Most of these operations are labour intensive and not mechanized (Pachauri, 2019). Besides, they are engaged in off-farm domestic activities such as cooking, cleaning, childcare, water and fuel collection and community activities. Shrinking remunerative opportunities in the farming sector has triggered migration of rural male folk to urban areas and also there is a shift in their job priorities to pursue employment in the rural non-farm sector in recent years. Since women did not feature predominantly in either of these trends, most of them are still engaged in agriculture, mostly as labourers and cultivators (Mehrotra, 2020). Vindicated by the fact that the number of female agricultural labourers in India increased by 24 per cent between 2001 and 2011, even though 7.7 million farmers left farming during the corresponding period. During the period when up to 34 per cent of men in rural areas migrated in search of employment and better economic opportunities, the corresponding figure for rural women is merely 3.6 per cent. A recent study of National Sample Survey Office (NSSO) found that 55 per cent of employed women in India

1. Introduction

Gender remains a critically important and largely ignored lens to view development issues across the world (Jayaraman, 2017). Gender inequality is the greatest human rights challenge of our time and also a critical economic, moral and social challenge (UN, 2015). There exists a significant gender gap in various sectors such as health, labour market opportunities, education and political representation all over the world. This mostly cause the restriction of women to stay at home for household chores. However, the associated disempowerment resulting from the adverse effects of restricting their way around outside world are seldom addressed in the development evaluation and monitoring processes (UNICEF, 2019). Therefore, gender equality and women empowerment are made explicit throughout the Sustainable Development Goals (SDGs). Drawing urgency to these efforts, SDG5 aims on full gender equality and women empowerment as a cross-cutting theme along with more than 30 related targets across other SDGs.

According to FAO (2011), rural women constitute about 43 percent of world’s agricultural labour force and are the agents of change and resilience builders. Even then they undergo greater constraints compared to the men counterparts in accessing technological interventions, productive resources, market information, services and financial assets. The contribution of women to food security often remains undervalued and invisible (FAO, 2011). This leads to inadequate reflection of women’s role in policy, legal and institutional frameworks. These have created difficult situations for them to address the multiple tasks of natural resource management, child rearing and family well-being, without more rural women inclusive development interventions. There would be a drastic reduction in the number of hungry population and malnourished children in the world if women had the same access as men to productive resources which in

turn helps to increase yields on their farms significantly (FAO, 2018). Furthermore, they are also under-represented in grassroot level institutions and administrative mechanisms and assumed to have less decision-making ability. In addition to these constraints, women face an imprudent work burden, at the same time much of their labour remains unpaid and unrecognized under the prevailing gender norms and discrimination. It is high time to include them in decision making process within the households, communities and institutions and thus to enhance women’s participation in governance (Bayeh, 2016).

The Context

The global food system is dynamic, with newer challenges every day with altering production and consumption subtleties. Roles played by various stakeholders of the global agricultural food system and rural development has changed tremendously in the last few decades. Smallholder farmer stakeholders to multinational companies are affected differently by the present difficulties likethe pandemic, climate change, and other factors. The various stakeholders respond, play roles to the challenges differently, and eventually become the agricultural value chains. The newer challenges affect the vulnerable actors like women, smallholder farmers, etc., who constitute asignificant portion of the value chains. This is specifically so in developing countries like India, where the processes of the ‘feminization of agriculture’progresses exponentially. Managing sucha value chain is highly challenging as access and sustainability of various actors differ considerably. Agro-advisory service toolkit for gender-responsive value chain analysis and development aims to select and analyze value chains for opportunities to improve the vulnerable situation and its actors seeking for resilience and reducing gender inequalities. It is now considered a development strategy to promote economic growth. There is an urgent need that thesmallholder farming systems are integrated into the value chains to serve local, national, regional, and global markets.

The chapter presents a brief overview of the gender-responsive value chain concept, factors that limit women’s participation in the value chain, interventions to improve the efficiency of value chains in a gendered perspective, and the development of value chain tools for addressing gender inequitiesin the agricultural system, and the challenges faced.

Soil

Soil is the upper most crust of earth surface which supports plant growth. It is defined as a three phase system in which plants grow. These phases are solid, liquid, and gas are essential. Solid part is frame which provides space for other two. It consists of minerals, clay minerals and organic matter. The soil is also a living system with millions of microbes that breakdown organic matter. The microbes are very essential and survive only when soil is well aerated and rich in organic matter and devoid of waterlogged conditions. Texture of soil depends on the size of solid particles and classified as gravel, coarse and fine sand, silt and clay. Soils are classified according to the relative distribution of these particles. Likewise, arrangement of these particles is referred as structure. Generally loamy soils and crumb structure are most growing preferred for fruit crops. According to level of organic matter, soils are classified as mineral soil or organic soil and soil having more than 20% organic matter is organic soil like peat and muck etc. Minerals and salts lend chemical properties to the soil like pH, alkalinity, sodicity, salinity and cation exchange capacity which influences the availability of nutrients in soil. Therefore, for making choice for soil, soil analysis in terms of following criteria isessential to decide on land capability. Maximum numbers of fruit orchards in India are depleted from micro and macro plant nutrients which interrupted the growth and development of the fruit plants and their quality. Therefore, like growers are not attain profit desired. To obtain marketable fruits, nutrients managements are highly beneficial to the fruit growers rainfed areas. Analysis of soil is useful to determine the level of the elements available in the orchards to get maximum yield.

Introduction

Food ingredients sector is indicating ample prospects for growth. The segment is an obligatory element for the growth of the food and beverage sector. These ingredients are also driving the development of the healthy functional foods industry to increase by 20% growth annually. Innovation in the food and beverage market, especially in the processed food domain, has created innumerable opportunities for new product development in the ingredients market as well. The segment is driven by the growing food processing industry and India is emerging as ingredients bowl of the future. Additionally, growing urbanization coupled with industrialization and changing lifestyles have led to growing demand for convenient food that offers health benefits, over and above the basic nutritional benefits of the foodstuff. There are nearly 10 to 15 broad classes of ingredients that include the very basic ingredients as well as certain value added ingredients that have niche applications. Key ingredients are preservatives, flavours, colours, hydrocolloids/stabilizers, emulsifiers, artificial sweeteners and value added health food ingredients such as omega-3-fatty acids prebiotics, probiotics etc. Until recently, there has been limited research into functional foods in meats, while functional foods in the dairy sector have been developed to a high degree. But meat is less allergenic than many other foods and much more research into the development and marketing of novel functional meat products is required. Such meat products would open up a new market for the meat industry. Nutraceutical and functional food industry is a very vibrant industry today with the claims and a clear mandate of health, wellness and prevention of diseases as one of its main goals.

Introduction

Hippocrate, an ancient physician, a great thinker and also often referred as father of medicine, for the first time conceive the idea nearly 2,500 years ago that a disease is caused due to natural factors such as environmental factors, diet, and living habits. He advocated the secret of healthy living in healthy food in his famous quote “Let food be thy medicine and medicine be thy food”. But unfortunately, this wisdom about food has faded with the time and we became dependent on synthetic medicines and drugs for even life style disorders. In the last century, research advancement in the field of food science and nutrition established food not only as a source of nutrition but also a source of active food components that aid specific functions and rejuvenated the Hippocrates concept. According to the Department of Health and Human Services, USA, daily diet of a person, plays a crucial role in 5 of 10 diseases which are the leading causes of death, such as diabetes (noninsulin dependent or type 2), stroke, coronary heart disease (CHD), specific type of cancer, and atherosclerosis. In the mid-1980s, term “functional food” was introduce in Japan and defined as food that contain active components either from plant or animal origin and provide physiological benefits in addition to the basic nutritional needs.

7.1 Introduction

Soil is an essential component of ecosystem sustaining all living vegetation, microorganisms, herbivores and carnivores. It is the outermost layer of the earth. It varies greatly in its physical and chemical properties which depend on its age and on the conditions (parent material, climate, topography and vegetation) under which it was formed. Processes such as leaching, weathering and microbial activity combine to make a whole range of different soil types, each of which has particular strengths and weaknesses for agricultural/ horticultural production.

The materials present in the soil are mostly in three states, i.e., solid, liquid and gaseous. They differ in their percentage from soil to soil. A good soil should have 5% organic matter, 45% mineral matter, 25% air and 25% water. So, while establishing an orchard, whole soil profile should be taken into consideration. Digging a pit shows the different layers of soil profile. Usually these are same and not distinct in many areas. Inorganic materials are the major component of most soils. They consist largely of mineral particles with specific physical and chemical properties which vary depending on the parent material and conditions under which the soil was formed. It is the inorganic fraction of soils which determines soil physical properties such as texture and has a large effect on structure, density, water retention and aeration. Air and water percentage in soil vary significantly with soil texture and weather conditions. The soil texture is a property which is determined largely by the relative proportions of sand, silt and clay particles content in it. The classification of soil based on particle size is termed as textural classification of soil. As per USDA classifications, clay particle size is less than 0.002 mm, silt size varies in between 0.002 to 0.05 mm and sand size in between 0.05 to 2.0 mm. On the basis of percentage of these particles present in a soil, the type of soil can be easily determined.

11.1 Introduction

• Pest problems in fruit production has increased the cost of tree/plant protection and squeezed the profit of the fruit growers.
• In India, there are several existing or potential key pests for each fruit trees whose population densities must be kept at sub-economic levels to sustain higher per unit production at the farmers’ fields.
• During the second part of 20th century, the major emphasis was on pest control, which involved a set of actions to avoid, alternate or delay impact of pests on crops, which mainly involved pesticide application with the sole aim of eradication.
• Since horticultural crops like fruits are intensively cultivated that allow more inputs cost, the use of insecticides for the control of specific pests of a particular fruit crop has increased manifold during the last few decades. However, the toxic materials generated from chemical use in crop production has polluted the environment, because majority of them are not biologically degradable. They have harmed consumers’ and farmers’ health.
• Uses of broad-spectrum chemicals for pest control have a very negative impact on our efforts to conserve biodiversity. Because of their broad-spectrum nature of effect, it not only kills enemy insects but also useful insects like honey bees.
• The pest control option based on pesticide applications virtually eliminates the bee keeping activity.

DEFINITION OF ENTREPRENEUR & ENTREPRENEURSHIP

Entrepreneurs: The word ‘Entrepreneur’ is derived from the French verb ‘ENTREPREDRE’, which means ‘to undertake’. The term is used to refer to anyone who undertakes the organizarion and management of an enterprise with independence and risk as well as the opportunity for profit. An Entrepreneur is a person who has a possession of any enterprise or venture and accepts significant accountability for the inherent risk and outcome.

Definitions of Entrepreneurs by Several Social Scientists are as follow

According to J.B. Say: An Entrepreneur is an economic agent, who unites all means of production, such as- Land, labour and capital to produce products.

Coconut is a tall un-branched palm growing to a height of 15-30 m. it has a stout trunkraising from the swollen base which is known as bole. It is surrounded by a mass of fibrous. The stem is terminating into a radiating crown of leaves. Leaves are known as fronds. Palm is monoecious produces one inflorescence is enclosed in a strong tough double sheath called as spathe. Fruit is known as drupe, large in size, one seeded, round, ovoid I shape and the fruit has smooth thin green skin known as exocarp below which there is a thick fibrous hook known as mesocarp. Tall varieties live up to 80 . 100 years and dwarf varieties are live up to 40 . 60 years. Tall varieties begin flowering 5-7 years after planting and dwarf varieties . 3 years after planting

5.1 Introduction

Palmyrah is a monocotyledon and perennial crop. The word “Borassus” was derived from a Greek word and it means the leathery covering of the fruit and “flabellifer”, means fan-bearer. The distinguishing characters of palm in this genus are their palmate, fanlike leaves and dioecious character, i.e., male and female flowers are borne on separate trees (sex ratio 1:1), allotetraploid (X= 8 or 9, n = 18), the male tree has a heteromorphic XY pair of chromosomes while the female has an XX pair (Sankaralingam et al., 1999). Next to coconut, palmyrah is the most abundant palm found in the world. Palmyrah thrives in arid conditions and is grown extensively in Tamil Nadu. Palakkad district of Kerala is popularly known as land of palmyra trees. Palmyra trees are known as the icon of this district and have a vast cultural, heritage and literary association.

Pomegranate (Punica granatum L.), an economically important fruit plant species, belongs to the family Punicaceae. It is an important fruit crop of arid and semiarid regions of the world and has been believed to be the symbol of fertility and abundance. Pomegranate is a highly remunerative crop for replacing subsistence farming and alleviating poverty. The plant is drought tolerant, winter hardy and can thrive well under desert condition. It is a good source of protein, carbohydrate, minerals, antioxidants, vitamins A, B and C, and has also been used in controlling diarrhoea, hyperacidity, tuberculosis, leprosy, abdominal pain and fever. Pomegranate juice contains antioxidants such as soluble polyphenols, tannins, anthocyanins and can be used in the treatment of cancer and chronic inflammation. It has enjoyed a reputation for its healthy dietetic and medicinal properties.

Indian Council of Food and Agriculture organized SEED WORLD-2019 (World Seed Trade and Technology Congress) from 18-21 September, 2019 at The Hotel Lalit Ashok, Bangalore and presented SEED INDUSTRY SCENARIO REPORT (ICFA, 2019; www.icfa.org.inwww.seedworld.in). The information as given below is largely based on this report and other presentations made during the congress, particularly one by Kapur (2019).

Varietal release and notification comes under the purview of the Seeds Act which aims to provide for regulating the quality of certain notified seeds for sale and for marketing and for the matters connected therewith. Released and notified varieties are offered for seed certification by the seed certification agencies which ensure that the varieties under certification meet certain prescribed field and seed standards failing which they stand to be rejected during the process of seed certification.

Black gram (Vigna mungo, L. Hepper, 2 n = 2 x = 22, family Leguminosae/ Fabaceae, essentially self-pollinated) has a global production of 3.2 million tons where India is the largest producer accounting for more than 70% of the global production followed by Myanmar and Thailand. Indian black gram area, production and productivity in 2010-11 were 3.25 million ha, 1.76 million tons and 522 kg/ha. The corresponding figures for 2015-16 were 3.62 million ha, 1.95 million tons and 537 kg/ha and the corresponding figures for 2016- 17 were 4.48 million ha, 2.83 million tons and 632 kg/ha. For 2017-18 (IV advance estimate), the figures were 5.44 million ha, 3.56 million tons and 655 kg/ha (Directorate of Pulses Development, 2018). These figures show a steady rise in black gram area, production and productivity over the years. This is the third important pulse crop in India after gram and pigeonpea. The three states namely, Madhya Pradesh, UP and Andhra Pradesh alone account for about 50% of the black gram area and production in India.

a) Babesia bigemina b) Leptospira interrogans

c) Theileria annulata d) Theileria parva

Sending a message from one place to another place, which are physically separated from each other, is called Communication. The Communication Engineering or Communication Technology deals with the design and development of engineering systems to transmit information from its source, and at the same time, to receive the same information at a remote destination with reliability, accuracy and quality.

The term ‘geo’ is a Greek word, it means the earth, and the term ‘spatial’ means parameter/feature measured, mapped or modeled with reference to distance or space. The geospatial technology refers to the technology that measure, model, analyze, map, or predict the features or phenomena that occur on earth and its surface.

With the invention of bitcoin in 2008, the world was exposed to a new technology paradigm called blockchain. Blockchain was conceptualized by an unknown person named as Satoshi Nakamoto in 2008. The identity of Satoshi Nakamoto is still not known. Nakamoto proposed the design of blockchain which uses digital signature and timestamps to enable secure and trusted online transaction without the need of any trusted regulatory or third party.

Plant biotechnology can be defined as the introduction of desirable traits into plants through plant tissue culture and genetic engineering techniques. The recombinant DNA technology is used to modify the expression of genes already present in the plants or to introduce new genes of other species with which the plant cannot be bred conventionally.

Complementary DNA (cDNA) is a double stranded DNA which is an exact copy of the mRNA, i.e. it consists of group of molecules possessing the information contained in various mRNAs but with termini equivalent to or related to those produced by restriction endonucleases. The use of cDNA is an absolute prerequisite for the expression of eukaryotic proteins in bacteria.
