Knowledge of structure is a basic element of biological research. Understanding structures of various degrees of complexity contributes to a better understanding of function, ontogenetic and physiologic processes, as well as phylogenetic relationships. In biological sciences, ultrastructure refers to the nanostructure of a biological specimen, such as a cell, tissue, or organ, at scales smaller than can be viewed with light microscopy. Electron microscopy (EM) has a great impact on our knowledge and understanding of ultrastructure.

Electron Microscopes are scientific instruments that use a beam of highly energetic electrons to examine objects on a very fine scale. This examination can yield information about the topography (surface features of an object), morphology (shape and size of the particles making up the object), composition (the elements and compounds that the object is composed of and the relative amounts of them) and crystallographic information (how the atoms are arranged in the object).

Electron Microscopes were developed due to the limitations of Light Microscopes which are limited by the physics of light to 500x or 1000x magnification and a resolution of 0.2 micrometers. In the early 1930’s this theoretical limit had been reached and there was a scientific desire to see the fine details of the interior structures of organic cells (nucleus, mitochondria...etc.). This required 10,000x plus magnification which was just not possible using Light Microscopes.

A Scanning electron microscope (SEM) is a type of electron microscope that images a sample by scanning it with a high-energy beam of electrons in a raster scan pattern. The electrons interact with the atoms that make up the sample producing signals that contain information about the sample’s surface topography, composition, and other properties such as electrical conductivity.

The types of signals produced by an SEM include secondary electrons, back-scattered electrons (BSE), characteristic X-rays, light (cathodoluminescence), specimen current and transmitted electrons. Secondary electron detectors are common in all SEMs, but it is rare that a singlemachine would havedetectors for allpossiblesignals. The signals result from interactions of the electron beam with atoms at or near the surface of the sample. In the most common or standard detection mode, secondary electron imaging or SEI, the SEM can produce very high-resolution images of a sample surface, revealing details less than 1 nm in size. Due to the very narrow electron beam, SEM micrographs have a large depth of field yielding a characteristic three dimensional appearance useful for understanding the surface structure of a sample.

8.1 Introduction

Electron Microscopes were developed due to the limitations of Light Microscopes which are limited by the physics of light to 500x or 1000x magnification and a resolution of 0.2 micrometers. In the early 1930’s this theoretical limit had been reached and there was a scientific desire to see the fine details of the interior structures of organic cells (nucleus, mitochondria etc.). This required 10,000x plus magnification which was just not possible using Light Microscopes. The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to see through the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931. The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in scanning the beam of electrons across the sample. Electron microscope has been a valuable tool in the development of scientific theory and it contributed greatly to biology, medicine and material sciences. This wide spread use of electron microscopes is based on the fact that they permit the observation and characterization of materials on a nanometer (nm) to micrometer (µm) scale. Electron Microscopes are scientific instruments that use a beam of highly energetic electrons to examine objects on a very fine scale. This examination can yield information about the topography (surface features of an object), morphology (shape and size of the particles making up the object), composition (the elements and compounds that the object is composed of and the relative amounts of them) and crystallographic information (how the atoms are arranged in the object). A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that can be detected and that contain information about the sample surface topography and composition. SEM can achieve resolution better than 1 nanometer. The combination of higher magnification, larger depth of focus, greater resolution, and ease of sample observation makes the SEM one of the most heavily used instruments in research areas today.

The scapula is more regularly triangular than in horse, relatively, wider at the vertebral end and narrower at the distal end. The scapular index is about T.0.6. The spine is more prominent and is placed further forward, so that the supras- pinous fossa is narrow and does not extend to the lower part of the bone. The spine is sinuous, bent backward in its middle, forward below. Its free border is somewhat thickened in its middle, but bears no distinct tuber. Instead of little more prominent, and is prolonged by a pointed production, the acromion, from which part of the deltoid muscle arises. The sub scapular fossa is shallow. The areas for the attachment of the stratus muscle are not very distinct. The nutri- ent foramen is usually in the lower third of the posterior border. The glenoid cavity is almost circular and without any distinct notch. The tuberosity is small and close to the glenoid cavity. The coracoid process is short and rounded. The cartilage resembles that of the horse. The tuberosity unites with the rest.

Introduction

Food is the most important requirement of every section of the society. But, mere availability of food sometimes is not enough and it does not mean that everybody is having access to a fair share of it or that every one has an adequate diet (Oshaug et al., 1994). Therefore, affordable food prices and adequate purchasing power with the people are equally important.

The need of food security was felt due to the gaps in food production and availability of sufficient food from domestic resources. Large proportion of the underfed population starves not because of general food shortage but due to the insufficient access to food supplies or insufficient income to purchase food.FAO (1999) estimated that there were 20.4 million undernourished people in India only).

Importance of maintaining food security over the world has been abundantly recognized since long. However, during 1974, FAO was called by the World Food Conference to establish a Committee on World Food Security so as to keep the world food situation under constant review and to suggest the strategies for rectifying the problems in problematic areas. Later, an International Undertaking on World Food Security was set up wherein member nations committed themselves to maintain food stocks for ensuring uninterrupted supply of foodgrains and to cope up with the problems of shortage in case of crop failure due to the natural calamities etc. Since then, the Committee on World Food Security monitors the implementation of the undertaking.

The United States of America (USA), European Union (EU), Brazil and China are four of the largest agricultural producers and users of agricultural pesticides in the world. Comparing the inclination and ability of different regulatory agencies to ban or eliminate pesticides that have the most potential for harm to humans and the environment can provide a glimpse into the effectiveness of each nation’s pesticide regulatory laws and oversight.

Scenario of Bioinputs reviews the broader market, production, consumption, and regulatory context surrounding bioinputs, with particular attention to biopesticides. The chapter discusses global availability and registration, major categories, market outlook, research needs, and industrial support. It then examines production infrastructure and consumption trends in India, including contributions from government organizations, agricultural institutions, private companies, and local laboratories. State-wise patterns and regulatory considerations are also addressed. By combining technical agriculture with market and institutional perspectives, the chapter helps readers understand the evolving bioinput sector, its production ecosystem, policy environment, commercialization potential, and opportunities for expanding sustainable crop-protection technologies. for stakeholders today.

Abstract

Domestic market both for cut flowers as well as loose flowers have increased significantly owing to rapid urbanization, changes in social attitude, increase in income level and the increasing habit of ‘saying it with flowers’. The per capita consumption of flowers is increasingly growing up due to which the production has been increased and non-traditional areas have emerged as important players in floricultural production. In this scenario of intensive production system, protected cultivation can be a viable option. Protected cultivation offers unique opportunities to produce high quality flowers round the year and insulate from weather vagaries thus, reduceing risk from the climatic variations. Protected structure comprises of high cost, medium cost and low cost polyhouses and each structure needs specific varieties and technologies to achieve maximum yield. Hence, breeding program should be based on structure and climate as it has been observed that varieties bred in Northern hemisphere under high cost greenhouses are not performing alike in medium and low cost polyhouses of Southern hemisphere. Breeding work in India has been carried out in wide range of floriculture crops. Breeding of many floricultural crops are in fact not always simple and straightforward due to polyploidy, complex ancestry involving one or more species, aneuploidy, and in some families self and cross sterility barriers, etc. It appears that breeders have vast opportunities to incorporate disease and insect screening and development of varieties for protected cultivation in routine breeding programs during the evaluation of seedlings. To develop varieties for such adversities, our research institutes should have enough infrastructures to carry out required research. In a few areas, protected cultivation has succeeded in India due to efforts of private companies and enterprising farmers. Recently, with greater efforts of ICAR a few public institutions have started breeding of flower varieties suited for protected cultivation.

Introduction

Fruit crops have been cultivated for centuries, both commercially and in amateur gardens, and many species covering a wide range of trees, shrubs, and non-woody perennials.Fruit crop species have certain common characteristics: they are long-lived, usually highly heterozygous, and clonally propagated from an elite mother plant. Fruits are increasingly recognized as an important component of a healthy diet, and consumption of temperate fruit and fruit products, especially juices and dairy derivatives, has risen sharply over the past decade.China is the largest producer of fruit crops with approximately.

• India ranks the second in fruit production.

• India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production.

• Over the last decade, the area under horticulture grew by 2.6% per annum and annual production increased by 4.8%.

• Production of fruit crops has increased from 50.9 Million Tonnes to 97.35 Million Tonnes since 2004-05 to 2017-18.

• Total production of fruits is highest in case of Andhra Pradesh followed by Maharashtra.

Agriculture in India is not of recent origin, but has a long history dating back to Neolithic age (7500–6500 B.C). It changed the life style of early man from nomadic hunter of wild berries and roots to cultivator of land. Agriculture is benefited from the wisdom and teachings of great saints. The wisdom gained and practices adopted have been passed down through generations. The traditional farmers have developed the nature friendly farming systems and practices such as mixed farming, mixed cropping, crop rotation etc. The great epics of ancient India convey the depth of knowledge possessed by the older generations of the farmers of India. The modern society has lost sight of the importance of the traditional knowledge, which had been subjected to a process of refinement through generations of experience. The ecological considerations shown by the traditional farmers in their farming activities are now a days is reflected in the resurgence of organic agriculture.

Historical Perspective of Organic Farming

The available ancient literature includes the four Vedas, nine Brahnanas, Aranyakas, Sutra literature, Susruta Samhita, Charaka Samhita, Upanishads, the epics Ramayana and Mahabharata, eighteen Puranas, Buddhist and Jain literature, and texts such as Krishi-Parashara, Kautilya’s, Artha-sastra, Panini’s Ashtadhyahi, Sangam literature of Tamils, Manusmirit, Varahamihira’s Brahat Samhita, Amarkosha, Kashyapiya-Krishisukti and Surapala’s Vriskshayurveda. This literature was most likely to have been composed between 6000 B.C. and 1000 A.D. The information related to the biodiversity and agriculture (including animal husbandry) is available in these texts. Rig-Veda is the most ancient literary work of India. It believed that Gods were the foremost among agriculturists. According to ‘Amarakosha’, Aryans were agriculturists. Manu and Kautilya prescribed agriculture, cattle rearing and commerce as essential subjects, which the king must learn. According to Patanjali the economy of the country depended on agriculture and cattle-breeding. Plenty of information is available in ‘Puranas’, which reveals that ancient Indians had intimate knowledge on all agricultural operations. Some of the well known ancient classics of India are namely, Kautilya’s‘Arthashastra’; Panini’s ‘Astadhyayi’; Patanjali’s ‘Mahabhasya’; Varahamihira’s ‘Brahat Samhita’; Amarsimha’s ‘Amarkosha’ and Encyclopedic works of Manasollasa. These classics testify the knowledge and wisdom of the people of ancient period. Technical book dealing exclusively with agriculture was Sage Parashara’s ‘Krishiparashara’ in 1000 A.D. Other important texts are Agni Purana and Krishi Sukti attributed to Kashyap (500 A.D.).

Scheduling irrigation is the process of determining when to irrigate and how much to irrigate. Selecting the appropriate time span in between two irrigation and applying the required volume of water in each irrigation, ensures saving of water, minimize energy use, higher crop yield and lower production costs. Irrigation applied earlier than due date causes loss of water through evaporation or deep percolation and later causes water stress to plants and thereby affects the growth and yield of the plants. Scheduling of irrigation may be required in two field conditions: (i) when availability of water is adequate, (ii) when availability of water is limited.

In the places where water is adequate scheduling of irrigation follows full irrigation with time sequence of minimum number of irrigation to ensure maximum yield and high water use efficiency. When water is limited its use is rationalized by using at the sensitive stages of the plants and withholding irrigation at other stages. The sensitive stages so selected that by using the available water provides possible maximum yield.

Irrigation Scheduling: Approaches and Advantages
Efficient irrigation scheduling aims to optimize crop yields while maximizing water use efficiency and minimizing soil damage. This involves determining the correct timing and amount of water to apply for each irrigation event. Several criteria can be used for scheduling irrigations, broadly classified into climatological, soil water regime, and plant-based approaches. The most suitable criterion depends on specific soil, plant, climate, and management factors.
Climatological Approach
Under conditions where soil water is readily available, the potential rate of water loss from a crop primarily depends on the atmosphere’s evaporative demand. This approach uses potential evapotranspiration (PET) or cumulative pan evaporation (CPE) over short periods as an index for irrigation scheduling.
Penman (1948) defined PET as the water transpired by a short, uniformly green crop completely covering the ground and never lacking water. He also noted that PET is generally a fraction of pan evaporation under the same conditions. PET can be estimated using various techniques, including lysimeters, energy balance calculations, aerodynamic approaches, and empirical formulas. Based on PET or crop water use rates over short periods, irrigation can be conveniently scheduled. Lysimeters isolate the crop root zone, allowing accurate determination of water balance components by controlling and measuring difficult-to-assess processes.
Soil Water Regime Approach
This approach uses the available soil water held between field capacity and the permanent wilting point in the effective crop root zone as a guide for irrigation scheduling. Soil moisture tension, which reflects how tightly water is held by soil particles, can also serve as an indicator.

The Government of India has launched several schemes and programs aimed at promoting farming-based livelihood opportunities, enhancing agricultural productivity, and supporting rural development. Here are some of the key schemes and initiatives:
1. Pradhan Mantri Kisan Samman Nidhi (PM-KISAN)
• Objective: Direct income support to small and marginal farmers.
• Features: Provides ?6,000 annually, payable in three installments, to help farmers purchase inputs and sustain their livelihoods.
2. Pradhan Mantri Fasal Bima Yojana (PMFBY)
• Objective: To provide risk coverage to farmers for crop loss.
• Features: Insurance for crops against natural calamities, pests, and diseases to ensure financial stability.
3. Soil Health Card Scheme
• Objective: To promote balanced use of fertilizers.
• Features: Issuance of soil health cards to farmers every 2 years, providing information on nutrient status and recommendations for fertilizers.
4. National Agricultural Market (eNAM)
• Objective: To facilitate online trading of agricultural products.
• Features: A unified platform for farmers, traders, and buyers to sell and purchase agricultural produce via online auctions.

There are numerous private organizations and non-governmental organizations (NGOs) around the world that are dedicated to promoting farming-based livelihood opportunities. These organizations often implement a variety of schemes and programs aimed at improving agricultural productivity, enhancing income, and providing support to farmers. Here are some common types of schemes and programs that such NGOs might engage in:
1. Training and Capacity Building
• Workshops and Training Programs: NGOs often organize training sessions for farmers on modern agricultural practices, sustainable farming techniques, pest management, organic farming, and efficient
water management.
• Farmer Field Schools: Practical learning environments where farmers can learn through hands-on experience and observation.
2. Access to Credit and Financial Services
• Microfinance and Cooperative Societies: NGOs may provide microloans or form cooperatives to give farmers access to credit and financial services without exorbitant interest rates.
• Savings Groups: Encouraging farmers to form savings groups to manage their finances better and prepare for lean seasons.

State governments and public organizations in various regions implement a multitude of schemes and programs to promote farming-based livelihood opportunities. These initiatives often aim to enhance agricultural productivity, improve rural livelihoods, provide financial assistance, and support sustainable farming practices. Here are some common types of schemes and examples that can be found in different Indian states:
1. Financial Assistance Programs
• Kisan Credit Card (KCC) Scheme: Provides farmers with timely and adequate credit for agricultural activities, helping them meet their cash flow needs during the farming season.
• Interest Subsidy Schemes: Certain states offer schemes that provide interest subsidies on agricultural loans to encourage borrowing for farming activities.
2. Crop Insurance Schemes
• Pradhan Mantri Fasal Bima Yojana (PMFBY): A central scheme adopted by many states that provides insurance coverage and financial support to farmers in the event of crop failure due to natural calamities.
3. Skill Development and Training Programs
• Integrated Skill Development Scheme (ISDS): Aimed at enhancing the skills of farmers and rural youth in various agricultural practices, including modern farming techniques, post-harvest management, and
value-added processing.

State governments in India implement various schemes and programs aimed at promoting farming-based livelihood opportunities. These initiatives often target different aspects of agriculture, including production, marketing, technology, and skill development. While the specific schemes can vary by state, here are some common types of programs and initiatives that state governments might implement:
1. Crop Support Schemes
• Minimum Support Price (MSP): Several state governments announce MSP for various crops to ensure farmers receive a fair price for their produce.
• Price Stabilization Funds: These are meant to support farmers during periods of low prices and ensure profitability.
2. Skill Development Programs
• Agricultural Skill Development Centers: Training programs aimed at enhancing the skills of farmers in modern agricultural practices, sustainable farming, and post-harvest management.
• Workshops and Seminars: Regular sessions are conducted for farmers to update them on new technologies and practices in agriculture.
3. Subsidies and Financial Assistance
• Seed and Fertilizer Subsidies: Financial help for farmers to purchase high-quality seeds and fertilizers.

The success of any country’s agricultural sector depends on the strength of its farmer producer companies (FPCs) or farmer producer organizations (FPOs). These organizations, formed by farmers for farmers, are essential for ensuring the fair and sustainable production and distribution of food. However, many FPCs face significant challenges, including lack of access to finance, technology, and markets. To address these challenges, governments and other institutions have implemented various schemes and programs to support FPCs. 

The development discourse on women nationally and internationally as discussed above, moved from Women in Development (WID) to Gender and Development (GAD) and Women’s Empowerment. This was reflected in the Government Plans and Policy Documents in their journey through more than six decades. Since independence many schemes were launched for the emancipation of women in the country.

In the Fifth Five Year Plan (1974-79), the development approach replaced the social welfare approach. This recognized women’s productive role and her contribution. The Sixth Five Year Plan (1980-85), is a landmark in the history of women’s development by emphasising on health, education and employment. In the Seventh Five Year Plan (1985-90) priority was given for programmes to improve the status of women. A major development for the empowerment of women was the 73rd constitutional amendment to the Panchayat Raj Act in 1993. This amendment specified that one-third of the posts of Sarpanch and Chairman of the block level assemblies (Samiti) and the district assembly (Zila Parishad) will be women. Today, mobilization of women’s groups particularly in rural areas has become a major strategy in bringing them into the public domain, developing leadership and increasing their access to resources. Indian women have higher visibility in the national and state policies.

Introduction 
Schiff base ligands (also called azomethines) were first revealed by German chemist Hugo Schiff in 1864. They are synthesized through a straightforward condensation reaction between an amine and a carbonyl compound (aldehyde or ketone). This reaction forms a characteristic imine group (>C=N-) while eliminating a water molecule as a byproduct. Schiff bases are highly versatile and serve as ligands for various transition metals, forming complexes with applications in catalysis, material science, and medicinal chemistry. Their ease of synthesis, tunable structure, and ability to stabilize metal centers make them valuable in both academic research and industrial processes (Cozzi, 2004). They can form stable complexes with almost all metal ions, offering various coordination geometries. Their flexibility makes them valuable in catalysis, medicinal chemistry, and materials science, with wide applications across these fields. Schiff base metal complexes exhibit exceptional catalytic performance in various high-temperature reactions (>100 °C), even under humid conditions. These complexes are widely employed in catalytic processes, such as oxidation, reduction, carbon-carbon bond formation, polymerization, and asymmetric synthesis (Zoubi et al., 2016). Recently, interest in olefin polymerization has increased due to their ability to catalyze the formation of commercially significant branched and linear polyethylenes. Their versatility, structural tunability, and high stability make them ideal for such applications, offering pathways to develop advanced materials with tailored properties for industrial and commercial use. Schiff base complexes thus remain central to modern catalysis research. These complexes have shown great potential in producing polymers with tailored properties, making them highly valuable in industrial applications. Schiff base complexes have gained attention for their catalytic roles, particularly in the reduction of ketones to alcohols and the alkylation of allylic substrates. These complexes, typically coordinating with metal ions, facilitate crucial organic transformations by stabilizing intermediates, offering an efficient and selective route for various chemical reactions. Schiff base complexes enable controlled ring-opening polymerization of cycloalkenes at low temperatures, offering precise molecular weight regulation without side reactions. In contrast, traditional catalysts like tungsten, molybdenum, or ruthenium with alkylating agents require high temperatures and lack molecular weight control, making Schiff bases more efficient for polymerization. The oxidation of hydrocarbons catalyzed by Schiff base complexes has garnered significant academic and industrial interest. These metal complexes are studied for their ability to facilitate efficient and selective oxidation reactions, offering insight into their catalytic activity and potential applications in chemical processes and industrial oxidation technologies. The ring-opening of large cycloalkanes is challenging due to their stability, but Schiff base complexes of cobalt(II) and chromium(III) effectively catalyze these reactions. These complexes enhance metal center reactivity and stabilize intermediates, enabling efficient cleavage of cyclic structures and expanding possibilities for catalytic transformations in synthetic and industrial chemistry. These complexes not only facilitate the process but also exhibit important enantioselectivity, creating them valuable catalysts in asymmetric synthesis and fine chemical production. Chiral Schiff base complexes have emerged as versatile and efficient catalysts in various organic transformations, particularly in asymmetric synthesis. Schiff bases derived from salen and binaphthyl frameworks are effective in Michael addition reactions, offering high enantioselectivity and catalytic efficiency. While transition metal complexes

In the backdrop of a predominantly agrarian economy, India has made tremendous advances in modern agriculture to meet both the food and nutritional security. In recent years, horticulture has assumed great importance mainly to augment nutritional security and secondarily as a highly cost-effective, remunerative and eco-friendly enterprise having vast export potential. To meet the challenges of research and development, tracer techniques have added the much needed fillip as they can be ingeniously applied to resolve issues which are not ordinarily possible using conventional techniques.

Science has individual, social, and institutional dimensions. Because of the social relevance of science, the dissemination of scientific information is crucial for its progress and contemporaneity. A scientist observes and then tries to make sense of that observation. She/he collects data, develops theories, uses hypothesis to understand and explain a thing, or a phenomenon, and then tries to find patterns emanating from her/his observations. Scientific knowledge keeps on changing.

Science is a blend of logic and imagination; therefore, there is always a possibility of disagreement and mismatch between them. A hypothesis is often untestable. Such untestable hypothesis are often rejected by the scientific community. “Science never pursues the illusory aim of making its answers final, or even probable. Its advance is, rather, towards the infinite yet attainable aim of ever discovering new, deeper, and more general problems, and of subjecting its ever tentative answers to ever renewed and ever more rigorous tests,” writes Karl Popper (1).

A scientist formulates, corrects, or discards the theories. The job of a scientist is to discriminate false idols from the real things. Science has built-in error correcting machinery, writes Carl Sagan (2). The error bars are insistent reminders to the fact that no knowledge is complete or perfect. It is used to exercise self-criticism. Each generation of scientists reduces the error bars a little. When we are self-indulgent and uncritical, when we confuse hopes with facts, we slide into pseudoscience and superstition. Sagan believed in maintaining an essential balance between the two attitudes: openness to new ideas, no matter how counter-intuitive they may be, and the most ruthlessly sceptical scrutiny of all ideas, old and new.

harmony with nature is proving winner in the long run. If the past 60 years led to the Green Revolution in agriculture which often became Greed Revolution, the next 60 year should be the emergence of love for nature, diversity and Sustainable Green Revolution. The two goals – Sustainability and Productivity are inter-related. It is also said that the main difference between the past and today is that our problems are truly global. We are also aware that globally and nationally the rich-poor divide is growing and though world produces enough food, nearly 800 million people remain food insecure. Among 8 millennium goals, eradication of poverty and hunger and environmental sustainability are perhaps the most prominent and complimentary. In his book, “Remember your Humanity – Pathway to food Security”, M.S.Swaminathan has emphasized that a pro-nature, pro-woman and pro-livelihood orientation should be the bottom line of all technological development and delivery program for food security. Mainstreaming of environmental concern in agriculture to avoid exploitative agriculture and ecological consequence is therefore the call of the time.
COMPASSION
The great Tibetan scholar and close companion of HH Dalai Lama, Thupten Jinpa defines compassion as a mental state endowed with a sense of concern for the suffering of others and aspirations to see that suffering is relieved. One of the highest understanding underlined at the global level and in the preparation of sustainable development goals is for a hunger free world and for

It has been repeatedly proving that Science& Technology that is close and in harmony with nature is proving winner in the long run. If the past 60 years led to the Green Revolution in agriculture which often became Greed Revolution, the next 60 year should be the emergence of love for nature, diversity and Sustainable Green Revolution. The two goals – Sustainability and Productivity are inter-related.

It is also said that the main difference between the past and today is that our problems are truly global. We are also aware that globally and nationally the rich-poor divide is growing and though world produces enough food, nearly 800 million people remain food insecure. Among 8 millennium goals, eradication of poverty and hunger and environmental sustainability are perhaps the most prominent and complimentary.

Mahatma Gandhi mentioned to those who wanted to serve rural India that their most useful contribution would be in linking brain with brawn.  Only such a combination of intellect and labour can lead to sustainable advances in the productivity and profitability of agricultural holdings.  West Bengal’s Bidhan Chandra Krishi Vishwavidyalaya (BCKV), almost four decades old, is a fitting example of such work.  It has helped the development of two more universities in the State, namely, West Bengal University of Animal & Fishery Sciences and the Uttar Banga Krishi Viswavidyalaya.  It is important that these three universities function like a consortium of educational institutions mandated to help in achieving agricultural advance, agrarian prosperity and rural transformation in the State.

Livestock and livelihoods are intimately related in our country.  The ownership of livestock is more egalitarian than that of land.  Similarly, West Bengal is full of fish ponds.  It is important that cultivation of crops like rice is done by adopting integrated pest management procedures, so that the water in which fish is cultivated does not get polluted with pesticides.

8.1. INTRODUCTION

The existence of Science could be in danger, if scientists did not record experiment performed, data collected and resuit obtained. Scientific writing doesn't mean to only keep records of progress and information, but to actually publish the results of studies in scientific journals. While keeping records is quite easy to do, publishing scientific papers can be really difficult, and especially for young researchers who are just starting to discover the world of scientific publications. A scientific writing is a method of communication, an attempt to tell others about some specific data that you have gathered and what you think those data mean in the context of your research. The rules of writing a scientific paper are rigid and are différent Uorr\ those that apply when we write an English theme. Scientific paper must be written clearly and concisely so that readers with backgrounds similar to yours can understand easily what you have done and how you have done it. The ultimate aim of most scientists is to publish their research findings in professional scientific reports. This includes peer-reviewed journal articles, which report original findings and contribute to the global pool of scientific knowledge. Scientists spend their time writing proposais, planning research, undertaking experiments, analysing data, tracing research, and reading related articles. Published reports and journal articles provide evidence of this dedication. Therefore, a scientific report is not simply some extra work that is done at the end of a project; it is an important historical document that provides evidence of work to the wider scientific community.

It is a must for the research scholars to attend scientific conferences of the Parasitology associations, after being members. It is advisable to become life-members of all three Parasitology associations, in India i.e. Indian Society of Parasitology, Lucknow, Indian Association for Advancement of Veterinary Parasitology, IVRI, Izatnagar and Indian Academy of Tropical Parasitology, JIPMER, Pondicherry. The annual conferences expose better chances to interlink with Parasitologists of the country and at times foreign scientists.

Introduction

Lentil is one of the important Rabi pulses. It is one of the oldest pulses crops and the most nutritious of the pulses. It has the potential to cover the risk of dryland agriculture. It is also used as a cover crop to check the soil erosion in problem areas. It is mostly eaten as ‘dal’. Lentil can also be used as green fodder. Its straw is also used as cattle. Being a leguminous crop, it restores the soil fertility.

Area of cultivation

Lentil is mostly cultivated in the northern and central parts of India. The important lentil growing states are Madhya Pradesh, Uttar Pradesh, Bihar, West Bengal, Orissa, Haryana, Rajasthan, Punjab and Assam. Uttar Pradesh and Madhya Pradesh together contribute 78% towards total national area as well as production.

Climatic requirements: Lentil requires cold climate during growth and warm temperature at the time of maturity. It can tolerate cold and frost winter up to great extent. The optimum temperature for growth is 18-30 degree centigrade. Excessive drought and/or high temperatures during the flowering and pod-fill period also reduce yields.

Soil: Lentil can be grown on a variety of soils such as light loams; alluvial soils and black cotton soils. This crop is also suited to the poorer types of soils, low lying areas such as paddy fields. Lentil does not tolerate flooded or waterlogged soils. Good drainage is required, because even short periods of exposure to waterlogged or flooded field conditions kill plants. A soil pH near 7.0 is best for lentil production. Acidic soils are not fit for growing lentil.

Rice is the most important cereal crop of India occupying about 44.0 million hectares land. It provides food and employment to millions of people in the country. Despite development of high yielding varieties and technological interventions the yield of rice is still low (3.20 tonnes/ha) in India. The reasons for low yield of rice are:

Lesser area under high yielding varieties

Limited availability of quality seed

Increased acidity/ sodicity in some parts of the country

Declined soil fertility

Unavailability of inputs, like fertilizers and seed, in time

Inefficient nutrient management including imbalanced use of nutrients

Improper crop rotations

Reduced availability of irrigation water

Inefficient management of weeds, diseases and insect-pests

The study of animal nutrition is a complex and important field that requires a detailed understanding of the various nutrients that are essential for the proper functioning of an animal’s body. These nutrients, including proteins, carbohydrates, vitamins, minerals, and fats, play a crucial role in metabolism and serve different functions such as providing energy, promoting growth and development, maintaining bodily functions, and supporting immunity. It is imperative to have a thorough knowledge of their quantitative requirements and the sources from which they can be obtained for scientific feeding practices. This knowledge has been gained through extensive research and experience over the years. Therefore, it is crucial for students studying nutrition to understand the methods used to acquire this knowledge and how it continues to evolve through ongoing research. This in-depth understanding will enable them to make informed decisions when it comes to providing optimal nutrition for animals.
Advantages of Scientific Feeding
Scientific feeding offers numerous advantages compared to standard feeding practices.
1. It guarantees that animals receive the correct amount and balance of nutrients, leading to improved health and a decreased risk of metabolic disorders.
2. It enhances feed utilization efficiency, resulting in lower production costs and reduced environmental impact in animal agriculture.
3. It improves the quality and safety of animal products, boosting their market value and consumer acceptance.
Challenges of Scientific Feeding
Despite its benefits, scientific feeding also encounters some challenges.
1. It requires skills and knowledge that small farmers may not have or can’t afford.

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

Heifers are future cows of the herd. Production and reproduction performance of cows depends on the care and management during calf and heifer stage. Rearing period of heifers can be divided into two stages, viz. from weaning to first service and service to calving.

Care of calf before birth

During the last 2-3 months of gestation the fetus grows rapidly. Calf draws a significant quantity of nutrients from the mothers system. It has to be replenished by additional feeding of the cow. A cow should be fed well-balanced ration for maintenance.

Introduction

Modern life style has taken the fitness out of the men. In ancient times, our life was labour oriented, whereas now we have lots of gadgetry to support our day to day living, thus making our life least labour oriented and we are now more susceptible to diseases diabetes, blood pressure and asthma were, until recently, associated with rich people only, however, these have now become common in urban and even rural areas irrespective of social status and age. The minimum physical exercise, coupled with carbohydrate and fat rich and fiber free diet and lots of tension in day to day life has given way to these diseases.

Since ages, plants have been mainstay medicinal support either in the form of herbal therapy (Like Ayurveda, Unani) or in the form of isolated active substances as being used in allopathic system of medicine. As per a WHO calculation, at least 80% population, in developing world, is dependent on direct use of medicinal plants.

Many of herbal therapies are very simple to use. It is therefore worthwhile to know about some of medicinal plants available commonly around us. The herbal preparations from these plants may not be dramatically effective to palliate disease, as allopathic medicines do, however, with judicious and regular use, we can avoid conversion of some of simple diseases into a major treatment problem.

It is fortunate that side effects of allopathic medicines have compelled us to reconsider the use of herbal remedies and physical exercise in the form of ‘Yoga’, aerobics or whatever you call it. The arid region of Northwest Rajasthan, although vegetated sparsely, is rich in medicinal plants. Some of the species, which are abound in the extreme arid ecosystem, have unique curative and therapeutic properties and some of them are getting a lot of mileage as nutraceuticals as well.

3.1 What is environment ?

The word environment is derived from a French word “environne” means to encircle or surround. Environment is defined as the circumstances or conditions that surround an organism or group of organisms. It is also defined as the complex of social or cultural conditions that affect an individual or community. Since humans inhabit the natural world and they build social, cultural and technological world, all constitute important parts of our environment.

Introduction

Horticulture is the science and art of propagation, production, utilization, improvement, harvesting and marketing of crops such as fruits, vegetables, ornamental plants, spices & condiments, medicinal & aromatic plants, plantation crops, postharvest technology etc. The term is derived from the Latin word hortus mean garden and cultura means to cultivate. These crops are diverse which includes annuals to perennials, edible to ornamentals, temperate to tropical, humid to desert, etc. Horticultural plants help to sustain and enrich people by providing nutritious food, medicines, enhances the beauty of surroundings, besides reducing carbon footprint. They also serves as raw material for various industries, such as processing, pharmaceutical, perfumery and cosmetics, chemical, confectionery, oils and paints, etc.

Importance of Horticultural Crops

The horticulture crops are a source of variability in farm produce as well as human diets. The comparative production per unit area of horticultural crops is much higher than field crops. They are not only a source of nutrients, vitamins, minerals, flavour, aroma and dietary fibres, but also contains health benefiting compounds and medicines. Ornamental horticulture have aesthetic value and protects the environment. These crops are also useful for cultivation in wasteland, poor quality soil, slopy, uneven or undulating lands. Mango and cashew nut are cultivated on a large scale in hilly and hill back areas. Such crops are of high value, labour intensive and generate employment throughout the year. Further they have national and international demand and are a good source of foreign exchange.

1.1 INTRODUCTION

India is the seventh largest country in the world in total geographical area and has second largest population next to China. Around 55 to 60 per cent of its population depend on agriculture and allied activities. Horticultural crops constitute a significant component of total agricultural production in the country. They require very intensive care in planting, carrying out different cultural operations, manipulating growth, harvesting, packing, transportation, marketing, storage and processing.

1.2 AGRICULTURE

The term agriculture broadly refers to the technology of raising plants and animals. Agriculture is the science, art or practice of cultivating soil, producing crops and raising livestock in varying degree of proportion followed by marketing. In other words, it is the activity of man to produce three basic needs of human being, i.e., food, fuel and fibre (3F) by using terrestrial resources optimally. The term agriculture is derived from two Latin words ager meaning field or land and cultura meaning cultivation or growing.

Introduction

Attaining food and nutritional security for a growing population and reducing poverty while sustaining agricultural production under the current scenario of depleting natural resources, increasing cost of inputs and impending negative impacts of climatic change are the major challenges the country is currently facing (FAO, 2009). In addition to these challenges, decline in soil organic matter, consequent deterioration of soil health, large scale erosion of fertile top-soil are the other bottle-necks for increasing agricultural productivity from a finite land resource base. These constraints are evolving mainly due to: (1) intensive tillage induced soil organic matter decline, soil structural degradation, water and wind erosion, reduced water infiltration, surface sealing and crusting, soil compaction, (2) insufficient return of organic material to soil owing to prevalent crop residue removal and burning (Prasad et al., 1999) and (3) mono-cropping. Conservation agricultural (CA) is a panacea to address these challenges the farming community of this country is presently facing. The CA system incorporates a holistic approach to agriculture that results in improved soil health and water quality, lower water and nutrient consumption, reduced soil loss, strategic land use and healthy biodiversity. It involves minimum soil disturbance, permanent soil cover through crop residues or cover crops, and crop rotations for achieving higher productivity (Hobbs et al., 2008).

Vertical farming is a system of growing crops in multiple layers in skyscrapers, to maximize the use of land by having a vertical design, whereby plants, animals, fungi and other life forms are cultivated for food, fuel and fibre by artificially stacking them vertically above each other (Despommier, 2009; Kalantari et al., 2017). It is estimated that nine acres in a horizontal farm is equal to 1 acre in a vertical farm. The concept of vertical farming started during the mid 90s by Dr Dickson Despomier, professor of Public and Environmental Health at Columbia University

1. Introduction

Fruits and vegetables represent highly perishable items of agriculture, mainly because of their high water content in fresh form. Their production, yield and management under agriculture is dealt essentially under horticulture. They abound in species and varieties in different geographic regions of the world, influenced by the agro-climatic conditions. Some are endemic and confined to certain geographic regions only. Accordingly, they may be tropical, sub-tropical or temperate, depending on their requirements of temperature for growth and yield.

Today, all the organisations rely on assessments of data provided by their users, consumers, internal procedures, and day to day operations to find new avenues for betterment and expansion of the product and services. These insights provide a large and intricate set of professionally generated, maintained, analyzed, and modified facts. "Big Data" refers to the vast amount of data (Bansal, 2022, April 6). For instance, social media platforms facilitate human contact every day and millions of people connect and share a vast array of diverse types of information through these platforms. Big Data is viewed as "incredibly significant" in academic research. In the Big Data context, data visualization tools and technologies are essential for analyzing large amounts of data and making decisions based on facts (Adilin Beatrice, 2021, March 2). Information and data are represented graphically in data visualization. By using visual components like charts, graphs, and maps, data visualization tools provide an intuitive way to observe and understand trends, outliers, and patterns in data. The process is called Big Data Analytics that describes the process of uncovering trends, patterns, and correlations in large amounts of raw data to help make data-informed decisions in various research works.

INTRODUCTION

The state of Manipur is located at the easternmost border of India and is characterized by flat valleys comprising of four valley districts (Bishnupur, Imphal East, Imphal West and Thoubal) surrounded by five mild to steep slope hill districts (Chandel, Churachanpur, Senapati, Tamenglong, and Ukhrul). The state is geographically bordered by Nagaland in the north, Burma in the east, Mizoram in the south and Assam in the west. The total geographical area of the state is 22, 327sq. km divided into 20, 089sq. km in the hills and 2, 238sq. km. in the valley. More than 98% of the population in the hill is in rural areas whereas around 60% of the population in the valley is in rural and around 40% are in the urban areas.

The AAS Unit, Imphal is located at 24045' N latitude, 93054' E longitude at an altitude of 774m above msl. The agro-climatic zone of the state covers sub tropical plain zone, sub tropical hill zone, temperate hill zone and sub temperate zone.

Introduction

Conservation of biodiversity and mitigation of global warming are two major environmental challenges today. In the context of climate change and the global carbon cycle, the relationship between plant biodiversity and soil organic carbon (SOC) sequestration has become a subject of considerable scientific interest. The Earth’s terrestrial vegetation plays a pivotal role in the global carbon cycle. Not only are tremendous amounts of carbon stored in the terrestrial vegetation, but large amounts are also actively exchanged between vegetation and the atmosphere. Anthropogenic perturbations exacerbate the emission of CO₂ from soil caused by decomposition of soil organic matter (SOM) or soil respiration (Schlesinger, 2000). The emissions are accentuated by agricultural activities including tropical deforestation and biomass burning, plowing, drainage of wetlands and low-input farming or shifting cultivation. In addition to its impact on decomposition of SOM, macroclimate has a large impact on a fraction of the SOC pool which is active. Conversion of natural to agricultural ecosystems increases maximum soil temperature and decreases soil moisture storage in the root zone, especially in drained agricultural soils (Lal, 1996). Thus, land use history has a strong impact on the SOC pool (Pulleman et al., 2000). The dynamic relationship between plant biodiversity and SOC depicts that any land use practices that increase vegetative cover, or reduce its removal, could have an influence on the global carbon budget by increasing the terrestrial carbon sink.

Introduction
Cocoa, Theobroma cacao L. popularly known as ‘Food of Gods’, the original source of chocolate, is indigenous to tropical humid forests on the lower eastern equatorial slopes of the Andes in South America. Cocoa spread to all over the tropical regions of the world from 18^th century onwards and is now grown in 58 countries covering 6.9 million ha worldwide, producing 4 million tons of cocoa. Cocoa is an important agricultural commodity and the key raw material in chocolate manufacture. Unlike large, industrialized crops, 80 to 90% of cocoa comes from small, family-run farms, with approximately five to six million cocoa farmers worldwide. Total production has increased by 13% from 4.3 million metric tons in 2008 to 4.8 million metric tons in 2012. This represents an average year-over-year production increase of 3.1%. This rate of increase may slow in the coming years, as cocoa trees are sensitive to changing weather patterns. Periods of drought and of excessive rain or wind can negatively impact the yield, and will continue to fluctuate as climate change intensifies. Most of the world’s cocoa is produced in West Africa (70%) followed by Asia and Oceania (15.6%) and Latin America (14.1%). World leaders in cocoa bean production are Ivory Coast, Ghana, Indonesia, Nigeria, Cameroon, Brazil, Ecuador, The Dominican Republic, and Malaysia, supplying 90% of the world production.

Introduction

Coconut is a versatile crop with several uses to mankind. Apart from the main product, the by-products obtained from the coconut crop have many alternative uses, thus, adding to the total value of the crop (Popenoe, 1969). A tremendous scope exists for use of coconut in a variety of non-food products. The development of cottage industries to produce such products is recommended to increase income of coconut growers. For historical reasons, cultivation of coconut and value addition of non-food products from coconut have taken deep roots in the state of Kerala. The rapid expansion of coconut cultivation in non-traditional areas increased the production of coconut and the industry has also developed gradually in the states of Tamil Nadu, Karnataka, Andhra Pradesh and Orissa. Among the non-food products of coconut, charcoal, activated carbon, and shell powder and coir or coconut fibre assume commercial importance. Other parts of the palm especially coconut wood and leaves are recently gaining attention.

Introduction

Groundnut (Arachis hypogaea L.) commonly called as Poor man’s cashew, is the 6^th most important oil seed crop in the world. It contains 48-50% oil, 26-28% protein and 11-27% carbohydrates. Groundnut is grown on 26.4 million hectare worldwide, with a total production of 37.1 million metric tons and an average productivity of 1.4 metric tons/ha. Developing countries constitute 97% of the global area and 94% of the global production of this crop (FAO, 2011). The production of groundnut is concentrated in Asia and Africa, where the crop is grown mostly by smallholder farmers under rain-fed conditions with limited inputs. Groundnuts (peanuts) are popularly used as seed oil in India. Since, they are obtained from the ground, they are called as groundnuts and also known as ‘Mungfali’ in Hindi, ‘Palleelu or Veru sanaga’ in Telugu, ‘Kadalai’ in Tamil, ‘Nilakkadala’ in Malayalam, ‘Kadale kaayi’ in Kannada, ‘Singdana’ in Gujarati and ‘Shengdaane’ in Marathi. Groundnuts are easily available round the year and almost everywhere in India. Groundnuts are also taken as snacks in many households especially in India. In reality, groundnuts are actually legumes. Since, they have all the properties of nuts like almonds, cashew nuts, etc., these are also included in the family of nuts.

Groundnut is the major oil seed of India. It accounts for 25% of total oil produced in India. Annual production of groundnut is around 9690 thousand tones. As the crop is grown in rainfed conditions, production and productivity are highly vulnerable to rainfall and exhibit huge fluctuation between the years. In India, groundnuts are produced both during Kharif (75%) and Rabi seasons (25%). Major production catchments of groundnut are located in Gujarat holding a share of 50.77% of total groundnut production, Andhra Pradesh holding a second place (12.69%) followed by Tamil Nadu (9.91%). Following are the top groundnut producing states of India (Table 1).
