Introduction

The development of ornamental fish and aquarium industry in India could be divided into three phases i.e., pre-juvenile, juvenile and post juvenile phase. The period, since independence till the beginning of the 21st century was the pre-juvenile phase of ornamental fish and aquarium industry. It was characterised by few numbers of aquarium shops mainly in metro and major cities of the country, availability of limited varieties of fish and aquarium products, high cost of products, very few number of hobbyists and lack of any institutional support. The ornamental fish and aquarium industry during this period had developed because of the individual efforts of ornamental f ish producers and aquarium traders. The total value of domestic aquarium trade was Rs. 55 crores, the export of ornamental fish from country was Rs. 1.74 crores (US$ 0.40 million) during 1999-2000 and aquarium keeping was known to be the hobby of rich only.

The span of juvenile phase was from the beginning of the 21st century to the year 2019-20. The hobby of aquarium keeping grew significantly during this period as about 1.25% of the urban house-hold were estimated to keep an aquarium at home or workplace. It was because availability of aquarium and aquarium accessories increased in the domestic market due to entry of Chinese products, the cost of fish and aquarium products reduced, the number of aquarium shops increased with existence even up to small cities and most importantly the availability of institutional support. The Marine Products Export Development Authority (MPEDA), Ministry of Commerce and Industry, Government of India, started providing financial assistance from 2006-07 to beneficiaries to set up ornamental fish production units. The schemes of MPEDA initially covered the coastal states of Karnataka, Kerala, Maharashtra, Tamil Nadu, and West Bengal and later inland states of Himachal Pradesh, Madhya Pradesh, and Rajasthan. A total of 579 ornamental fish production units of different grades were established in all these states but the scheme was closed in the year 2014 15. It was followed by another pilot project implemented by National Fisheries Development Board (NFDB), Ministry of Fisheries, Animal husbandry and Dairying, Government of India (GOI) with a proposed investment of Rs. 61.98 crores. It covered six coastal states namely Gujarat, Karnataka, Kerala, Maharashtra, Tamil Nadu, and West Bengal, an inland state Bihar and one hilly state of Assam from north-east. The total value of domestic aquarium trade was about Rs. 555 crores during 2019-20 and the export of ornamental fish from country was Rs. 10.84 crores. The aquarium keeping was known to be the hobby of common man now.

Importance of Policies for Extension
Policies play an important role in the field of extension, which involves the transfer of knowledge and technology from researcher to farmers, communities and other stakeholders. Following are some specific reasons why policies are vital for extension:
1. Accountability: Policies may provide basis for monitoring and evaluation of extension activities and for holding extension professionals and other stakeholders accountable for their actions.
2. Innovation: Policies can promote innovation in extension by encouraging the adoption of new technology, approaches and practices, encouraging experimentation, collaboration and continuous improvement. By removing barriers to adoption and offering rewards for testing, policies can also aid in the creation of an atmosphere that fosters innovation.
3. Consistency: Policies aid in ensuring that extension activities are consistent with the goals and objectives of organization or program. It offers a framework for decision-making that enables the uniform
handling of similar circumstances.

Study of living organisms in soil is referred to as soil biology (Greek word bios= life, logos = study). The soil is teeming with millions of living organisms which make it a living and a dynamic system.

Personality, a term deeply ingrained in our everyday discourse, encapsulates the essence of what makes individuals unique. This multifaceted construct has intrigued scholars, philosophers, and psychologists alike throughout history. Its exploration not only delves into the intricacies of human nature but also seeks to unravel the complexities of individual differences and behavior.

The journey to understand personality spans millennia, with its roots tracing back to ancient civilizations. Early philosophical inquiries by thinkers such as Plato and Aristotle pondered the nature of character and temperament, laying the groundwork for later conceptualizations. However, it was not until the late 19th and early 20th centuries that personality garnered significant attention within the realm of scientific inquiry. The emergence of psychology as a distinct discipline heralded a new era of systematic study into the intricacies of human behavior and individual differences. Influential figures like Sigmund Freud, Carl Jung, and Alfred Adler pioneered seminal theories that sought to elucidate the dynamics of personality development, the unconscious mind, and the interplay of internal drives and external influences.

Abstract

The Tamil Nadu is one of the leading states in groundwater development. Since the surface water resources have been fully exploited for irrigation, the groundwater is massively mined for agriculture, domestic and industrial purposes. The paper provides a synthesis of whole groundwater related issues including basin wise groundwater conditions, the aquifer types, geogenic water quality and quality deterioration due to anthropogenic activities, need for recharge, the utility of Remote Sensing & GIS etc. The paper has come out with set of recommendations as the concluding remarks.

Nursery management is indeed a very important operation in successful growing of vegetables especially those, which are raised through seedlings in properly managed nursery beds. Raising nursery from seed provides an easy and convenient way to nourish tender young seedlings in a well-managed small and compact area. The nursery area can be conveniently protected from natural hazards, seed borne diseases and insect-pests and can be well managed economically. Some of the vegetable seeds are very costly, for which it is necessary to raise nursery in the most-optimum conditions. In areas where land holdings are small (in hills), nursery raising helps in making economical use of land for about one month and provides enough time to mature for previous crop, harvesting, threshing and land preparation for next crop. Most of the vegetable crops like cabbage, cauliflower, tomato, eggplant, sweet pepper, hot pepper, onion, celery, parsley, lettuce, etc. can successfully be raised through seed by growing them in the nursery and then transplanting in the field.

“A vegetable nursery is a place or an establishment for raising or handling young vegetable seedlings until they are ready for more permanent planting.”

Nursery can be maintained either for personal or commercial purpose, and each has its own advantages and disadvantages. Seedlings raised for own planting will be true to type, sound and healthy. On the other hand, seedlings purchased from outside may not be true to type, vigorous and healthy and may not arrive at destination in due course of time.

Most of the plants undergo a period of rest, and in this period, the growth activities temporarily halt. The whole plant looses its aerial parts and undergoes a rest period in the form of rhizome, corm, or tuber. Researchers who study fruit trees use the term rest for dormancy (Samish, 1954). This period is sometimes called as quiescence. The term rest and quiescence can be included under common category dormancy. Some workers differentiate the term dormancy and rest period (Burton, 1964). Wareing and Co-workers (Robinson and Wareing, 1964; Wareing et al., 1964) isolated dormancy inducing substance in sycamore seedlings (Acer pseudoplatanus) which was named as dormin. Further, analysis of this substance by Cornforth et al. (1965) reveals that dormin was identical to Abscisin-II (a substance speeding the abscission of the young flowers of Lupinus luteus and have antiauxin effect).

Dormancy can be defined as an arrest in development of buds, seeds, embryos, or spores under conditions otherwise suited for growth (Taylorson and Hendricks, 1977). It is a survival strategy (exhibited by many plant species), which enables them to survive in climates where part of the year such as winter or dry seasons is unsuitable for growth. The dormancy may be due to the factors within the dormant organ or seed itself and it is called spontaneous dormancy. This type of dormancy is found in seeds, buds and perenating organs like tubers, bulbs, bulbils, corms and rhizomes. In some weeds, dormancy is caused by high or low temperature and this type of dormancy is called as imposed dormancy. Seeds normally germinate in darkness but are inhibited by light are considered to become dormant after exposure to light (Bewley and Black, 1982; 1985). Seeds that require light for germination are said to be photo dormant.

1. Introduction to Agroforestry

Agroforestry stands at the intersection of agriculture and forestry, embodying a holistic approach to land management that harnesses the synergies between trees, crops, and livestock. At its essence, agroforestry transcends conventional farming practices, weaving together the ecological, economic, and social dimensions of sustainable land use.

Defining Agroforestry

In the tapestry of agroforestry, the definition extends beyond the mere coexistence of trees and crops; it embodies a philosophy of intentional and symbiotic relationships. Agroforestry is a deliberate and dynamic land-use strategy where trees are integrated into agricultural systems, fostering mutually beneficial interactions.

This chapter reviews the research work done in the fields related to the objectives of the study. In any scientific investigation or research a comprehensive review of relevant literature is very essential. Its main function apart from determining the work done before concerning the problem area i.e. area of investigation, it provides an insight into the methods and procedures and create a basis for interpretation of findings. As direct references on all the item are not in abundance, certain specific references along with some indirect references have been incorporated this chapter for the purpose of meaningful use.
2.1. Ecosystem Services and Conservation Agriculture
Acharya, S. K. and Chatterjee, R. (2019) found that conservation agriculture may help in re-building agro-ecology by maintaining carbon sequestration, maintaining soil health, checking soil erosion and ground water depletion, energy balance, mitigating climate change related problems through maintaining ecosystem services.
Ayyam, V., Palanivel, S., and Chandrakasan, S. (2019) stated that CA embraces higher rates of carbon sequestration, organic matter accumulation, soil erosion reduction, and its associated improvement in soil biological properties. Additionally, there is reduction in greenhouse gas emission as a result of CA. Adoption of CA-based farming practices particularly in areas facing notable land degradation and depleting natural resources delineates a win-win scenario due to improved crop yield and trends of increasing soil fertility and scope for climate change adaptation to recuperate degraded soils and improve ecosystem services.

Introduction

Persistent use of conventional farming practices based on extensive tillage, especially when combined with removal or in-situ burning of crop residues, has magnified soil erosion losses and swiftly degraded soil resource base. One of the glaring examples for the aforementioned statement is the ‘Dust Bowl’ in the U.S during 1930s in Great plains, where 91 M ha of land was degraded by severe soil erosion (Hobbs, 2007).

One of the primary challenges of our time is to feed growing and more demanding world population with reduced external inputs and minimal environmental impacts (nature paper). Conservation Agriculture (CA) is a set of management practices for sustainable agricultural production without excessively disturbing the soils, while protecting it from the processes of soil degradation like erosion, compaction, aggregate breakdown, loss of organic matter, leaching of nutrients, and processes that are accentuating due to anthropogenic interactions in the presence of extremes of weather and management practices. The organic materials conserved through this practice are decomposed slowly, and much of materials are incorporated into the surface soil layer, thus reducing the liberation rate of carbon as CO₂ into the atmosphere. In the total balance, carbon is sequestered in the soil, and turns the soil into a net sink of carbon. So, CA enhance soil health by improving soil aggregation, reducing compaction through promotion of biological tillage, increasing surface soil organic matter and carbon content, and moderating soil temperature and weed suppression. CA reduces cost of cultivation, saves time, increases yield through timelier seeding/planting, reduces pest and diseases through stimulation of biological diversity, and reduces green house gas emissions.

Machinery development, refinement and adoption for a range of soil and cropping situations will be fundamental in any success to promote conservation agriculture practices. Agricultural machinery or tools, which support conservation agriculture generally refer to the cultivation systems with minimum or zero tillage and in-situ management of crop residues. Minimum tillage is aimed at reducing tillage to the minimum necessary that would facilitate favorable seedbed condition for satisfactory establishment of crop. Zero tillage is however an extreme form of minimum tillage. With the development of direct drilling machines, almost all research work was attempted to define the responses of direct-drilled seeds in relation to soil micro-environments. Different designs of direct drilling machines viz. zero till drill, no till plant drill, strip till drill, and rotary slit no till drill have been developed with controlled traffic measures for energy efficient and cost-effective seeding of crops without tillage. In this paper various issues, challenges and prospects of conservation agriculture in India has been discussed.

Introduction

Consumers are nowadays very much concerned about the food they purchase and consume. Consumer wants the food containing antioxidant properties or can say functional food in safe and stable forms, so that the availability of daily requirements of functional food ingredient must be ensured for normal growth and development of the body. The functional food that can provide a health benefit such as increased dietary fibre, vitamins or minerals to the body. The incorporation of antioxidant compounds acts as an efficient way to fight against reactive oxygen species (ROS) generated in our body. As it is already known that the ROS causes oxidative stress and acts as a main trigger for different life threatening chronic diseases like cancer, diabetes, cardiovascular disease, aging etc. Therefore, seeing the consumers’ demand for value added products with bioactive ingredients, all small and large scale food industries are taking initiatives to process different types of food (fruits, vegetables, dairy, sea food, animal, microbial products etc.) to extract and purify its active fraction of functional ingredients to valorize different value added products. Functional ingredients may also be derived from different food wastes generated during processing of food. This practice provides additional economic benefits to food businesses. Food industries are also giving importance to different processing methods to extract high quality of functional food ingredients in large quantity because processing method affects the concentration of extracted bioactive compounds. The simple addition of functional ingredients may cause an unwanted and negative change of sensory and texture of food. Therefore, using novel processing technologies such as microencapsulation, the negative changes could be minimized or avoided because these technologies could prevent the inactivation of bioactive ingredients.

1.1 Background

The historical backdrop of irrigation is rich and diverse, reflecting the ingenuity of civilizations in adapting to their environments to meet the basic human need for sustenance. Ancient cultures such as the Sumerians, Egyptians, and Chinese were pioneers in developing rudimentary irrigation systems, channeling water from rivers, and constructing canals to nourish their crops. These early practices laid the foundation for the evolution of irrigation, marking a significant transition from relying solely on rainfall to actively controlling water distribution.

Introduction 
The evolution of public administration in the digital age has been anything but linear. As governments worldwide grapple with waves of technological advancement, the boundaries between reform phases such as e-government, e-governance, digital government, and digital governance often blur. Transformations occur unevenly across sectors and regions, with older paradigms coexisting with or even outlasting newer innovations. As Dunleavy, Margetts, Bastow, and Tinkler (2006, p. 216) perceptively observe: “Defining periods in the evolution of any complex system, such as public management systems in advanced industrial countries, is tricky. New developments accumulate while older trends are still playing out and flourishing. Relatively established ideas move from leading-edge countries or sectors to implementation in previous laggard areas, even as the same ideas are being repudiated or reversed in the erstwhile pioneering locations. Moreover, a confusing welter of changes goes on simultaneously, amongst which it is difficult to distinguish ephemeral and hyped-up innovations from those that are fundamental and longerlasting”. This observation aptly captures the administrative reforms’ non-linear and layered character in the digital era. The coexistence of multiple reform paradigms ranging from early e-government initiatives focused on service delivery, to broader e-governance aimed at leveraging technologies for participatory governance, and finally to the strategic integration seen in digital governance illustrates how public sector innovation is cumulative and contested. Digital governance, in particular, cannot replace previous phases. Instead, it serves as their expansion and convergence, wherein technology, data, and citizen-centricity are embedded in policymaking, service design, and institutional accountability. To fully understand the rise of digital governance, examining the broader historical trajectory of administrative reforms is important. Since the 1960s and 1970s, such reforms have consistently remained a focal point for both

Preamble

The recent advances in embryo transfer protocols have placed these techniques as widely adopted means of developing experimental models to understand complex biological processes such as feto-maternal dialogue, fetal programming and maternal effects on early development. This has noticeably widened the scope of embryo transfer programs which are now not only limited to transferring the genetically superior embryos from donors to recipients for faster genetic improvement, or as only the therapeutic tools in human medicine, but has embarked these techniques as basic research tools in biological research. It is however critical to achieve effective synchronization between donors and recipients along with optimal superovulation in donors to get more number of transferable embryos and subsequently greater conception rates of recipients. For transfer, the embryos are collected Day 6 or 7 post insemination of donors. An overall discussion of sequential steps to achieve successful embryo transfer along with recent advances in the subject area and its possible future scope is discussed in this chapter.

Farm Animals and Horses Urinary system mainly comprises of kidneys, ureters, bladder and urethra. In farm animals, diseases of urinary bladder and urethra are diagnosed with more frequency than that of kidneys. Renal insufficiency is observed as a sequel in cases of nephritis (pyelo or embolic nephritis), nephrosis or amyloidosis. Urinary diseases are clinically manifested with pain, dysuria, and variation in urine flow (polyuria, oliguria to anuria) and changes in urine (proteinuria, hematuria, hemoglobinuria, myoglobinuria, glycosuria, ketonuria, crystalluria, pyuria, and cellular casts). Decreased body weight, loss of appetite, polyuria, polydipsia and ventral edema are seen in chronic renal failure. Like dogs and cats, urinary tract is not accessible in large farm animals for clinical examination. Trans abdominal palpation of kidneys is feasible in calves and small ruminants. Rectal palpation, urine examination and renal function tests provide diagnostic assistance in the diseases of urinary tract in large animals. Clinical Manifestations Dysuria and abdominal pain are generally seen in urinary tract disease. Acute pain from urinary tract disease is not common. Pain associated with urethral obstruction and bladder

Bones of the animal body makes a skeleton system and helps in locomotion and support soft tissues. The proportion of bones in animal body varies with the animal species as they contribute 12-28 percent in cattle and buffalo, 17-35 percent in sheep and lambs, 50percent in bobby calves, 25 percent in veal calves, 12-20 percent in pigs and 8-17 percent in poultry. As the age advances bones becomes rigid due to ossification of cartilages but in older age bones becomes brittle and fragile due to reduction in bone organic matter.

ABSTRACT

Microorganisms play a key role for the proper running of the ecosystem. They help in nitrogen fixation, which is unique and most necessary property found only in this group. They help in decompositions, mineralization, nutrient cycling, phosphate solubilization, soil aggregate formation, symbioses, parasitism and many other important works. A great emphasis has been given by many scientists to conserve the microbial diversity. Developing human civilization has a great negative impact not only on the above ground biodiversity but also on the belowground biodiversity. This article is an overview, what important and crucial role nitrogen fixers play for maintaining soil and plant health. Nitrogen fixer not only fixes atmospheric nitrogen but also produces growth promoting hormones which are very important for plant growth. 

Indian agriculture is characterized by small farm holdings. The average per capita land holding is speculated to squeeze to 0.10 ha by 2050. The proportion of marginal holdings is to swell more due to the growing population, inheritance laws of division of land and diversion of agricultural land to non-agricultural purposes. But we need around 457 Mt food grains to feed our nation by 2050 as against the present level production of about 257 Mt. Significant changes are also taking place in domestic and international demand for crop products due to improvement in income and standard of living, fast urbanization, and changing life styles and food preference patterns. The food demand is projected to grow annually at 2.0 % for cereals as against 3-4 % for edible oils and pulses, 4-5% for milk and milk products, meat, fish, eggs, fruits, vegetables, sugar and gur. In contrast, association of emerging problems like declining per capita land availability, increasing nutritional insecurity, decrease in factor productivity, increasing risk with individual farm component, unsustainability of cropping systems and unwillingness of young farmers towards farming lead to an apprehension in achieving the target. Farming system which aims at long term productivity, profitability, recycling of resources and employment generation, comes out as a major strategy to tackle all such problems. In farming system, various components of farming are integrated based on the cardinal principles of minimizing the competition and maximizing the complementarity between the enterprises so as to improve productivity and profitability as well as resource conservation along with maintenance of the environment. A survey conducted by the AICRP on Integrated Farming Systems indicates existence of 19 predominant farming systems with majority (85%) as crop + livestock (Gangwar and Ravisankar, 2014). Crop dominant farming systems are existing in most of the states such as Andhra Pradesh, Bihar, Chattisgarh, Goa, Haryana, Jammu and Kashmir, Jharkhand, Kerala, Karnataka, Madhya Pradesh, North-East, Maharashtra, Odisha, Punjab, Tamil Nadu, Uttar Pradesh and Uttaranchal while livestock dominant systems, are present in Rajasthan and Parts of Gujarat. West Bengal, parts of Odisha and Assam states have the fisheries as a major source of income to the existing farming systems. The scope for promotion of horticulture (fruit) based systems exists in Jammu and Kashmir, Himachal Pradesh, Maharashtra, parts of Uttar Pradesh and in Sikkim while plantation dominant systems, are available in Andaman and Nicobar Islands and Kerala. Further, the contribution of crop and livestock to gross income of existing farming systems in 732 marginal households in 30 districts of 20 states in various NARP zones of India indicates that in majority of the place crop component contributes more than 50 % while at few districts such as Samba (Jammu), Aurangabad (Maharashtra), Mehsana and Panchmahal (Gujarat), livestock component contributes either equally or more. Thus cropping systems play a pivotal role in most of the farming systems of India.
