Prevailing climate and weather conditions play crucial role in production and quality of various fruits including mango (Mangifera indica L.). In India, mango has 2.3 million ha area with annual production of 20.5 million tonnes and average productivity of 8.9 t/ha. However, erratic precipitation and high temperature during flowering and fruit setting induced mainly due to climatic disturbance in the recent past had adversely impacted the production potential of mango in subtropics. Analysis of twenty years (2001-02 to 2021-22) weather data of ICAR CISH, Lucknow, indicated that average annual rainfall of the region is 956.41 mm spread over 25-30 number of rainydays.

Underexploited

Unexploited fruit crops, jackfruit, tamarind, jamun, karonda, star fruit, etc having high nutritive value, are gaining popularly among the people. Similarly, many exotic fruits, Dragon fruit (Hylocereus spp), Avocado (Persea Americana Miller), Rambutan (Nephelium lappaceum L.), Mangosteen (Garcinia mangostana L), Passion fruit (Passiflora edulis Sims), Durian (Durio zibethinus L.,) Longan (Dimocarpus longan Lour) have been introduced in India. Exploitation of their genetic diversity could provide nutritional and livelihood security. There is a need to know about nutritional composition and health significance of these crops. Therefore, efforts have been made to know their potential nutritional and health benefits

Microgreens, popularly known as “vegetable confetti,” are tender young greens that are grown from seeds of cereals, vegetables, and herbs. These shoots are typically harvested 7-21 days after germination when they are just (2.5-7.5 cm tall. At this stage, microgreens have a central stalk, two mature cotyledon leaves, and a second pair of tender true leaves. Compared to baby greens and sprouts, they are bigger than sprouts and smaller than baby greens. Their distinctive color, texture, and flavour can be either sweet or spicy.). Microgreens are especially important because of their high amount of micronutrients and bioactive substances.

Ecological engineering has recently emerged as a paradigm for considering pest management approaches that rely on the use of cultural techniques to manipulate farm habitat and to enhance biological control. In contrast to the intensive use of ecosystems, these days to enhance productivity can affect agro-ecosystems through soil and water depletion, biodiversity loss, challenging pest problems and disruption in flow of ecosystem services. Ecological engineering for pest management mainly focuses on increasing the abundance, diversity and function of natural enemies in horticultural crops habitats by providing refuges and alternate or supplementary food resources and also attracts different kinds of pollinators like honeybees.

Introduction

The term “biological control” was first used by Smith in 1919 to signify the use of natural enemies (whether introduced or otherwise manipulated) to control insect pests. DeBach (1964) defined biological control as the action of parasites, predators, or pathogens that maintain another organism's population density at a lower average than would occur in their absence (Dhaliwal and Arora, 2016). According to a recent definition by Eilenberg et al. (2001) biological control or biocontrol is “The use of living organisms to suppress the population density or impact of a specific pest organism, making it less abundant or less damaging than it would otherwise be.

Points to Ponder

Collect cytological samples (FNAB) only from enlarged lymph nodes

Do not make attempt to collect samples from normal lymph nodes unless to study normal picture (Academic interest).

Care to be taken to hold the lymph node while collecting FNAB

Otherwise needle may go into perinodal fat yielding fat tissue so also in obesity

Submandibular salivary gland enlargement mimic submandibular lymph node enlargement

Salivary tissue will show epithelial cells, acinar formation and no lymphocytes

Cytological diagnosis of lymphadenopathies can be comfortably and confidently made.

Peripheral Lymph Nodes

Interpretation of Drainage Patterns Through Aerial Photographs

Aerial photographs can provide a useful tool for interpreting the drainage patterns of a landscape. Drainage patterns are formed by the natural movement of water across the land and the way in which it flows from high to low areas, creating channels and streams that eventually converge into larger rivers and bodies of water. Different types of drainage patterns can be identified through aerial photographs, which can help to understand the underlying geology and topography of the landscape.

Here are some of the different drainage patterns that can be identified through aerial photographs:

1. Dendritic pattern

This pattern resembles the branches of a tree and is the most common type of drainage pattern. It occurs in areas where the underlying rock or soil is uniform and has no preferred direction of erosion. The streams converge into larger rivers, which may flow in a particular direction.

Research methodology is a detailed plan of investigation and the blue print of procedure for carrying out the research. In this chapter, discussion on the methodology has been made to understand the concepts, methods and techniques, which are utilized to design the study, collect information, analyzing data and interpreting the findings for revelation of truth and formulation of theories. The entire chapter has been broken up under following sub-heads for easy understanding:

1. Locale of research
2. Sampling design
3. Pilot study
4. Variables and their measurements

To tackle modern-day challenges and attain a sustainable growth while managing farm enterprises, the farmers have to undergo rigorous behavioral change to transform themselves as entrepreneur. Thus, the present chapter deals with incorporating an understanding about the idea of an entrepreneur and entrepreneurship and the organization level, present status and promotional opportunities of FPOs.

2.1 Who is an Entrepreneur?

An entrepreneur is someone or a group of individuals who conceptualize, start, and sustain for a long enough period of time a social organization that provides financial rewards, or, to put it another way, who see a business opportunity and create a firm to pursue it. (Cole,1968)

The impact of biotic and abiotic constraints, the machinery revolution, faster access to information, city development, social and economic context, climate changes that affect agricultural products and people's movement from one region to another, population income, new cropping technologies adapted to people's demand for food diversification and supply, technical and genetic progress, the impact of biotic and abiotic constraints, the machinery revolution, faster access to information and city development have all had an impact on agricultural market trends over the last ten years. (Bonciu et al., 2020a, Bonciu et al., 2020b).

M-Agriculture

Mobile phones have changed the scenario of telecommunication. It is a source of communication for fast dissemination of information. Today, mobile usage has enabled farming communities to access agricultural and other business information without travelling long distances or reducing costs, time and money. Keeping in view the lower ratio of the farmer to the extension worker (1000: 1) and the inability of the extension workers to guide the farmers as per their information needs, the new concept of m-Agriculture (m-Krishi) has emerged at the beginning of twenty-first century all over the world including India.

Renewable Energy

Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished.

Renewable energy is energy derived from natural resources that replenish themselves over a period without depleting the Earth's resources.

The term "renewable energy" is energy derived from a broad spectrum of resources, all of which are based on self-renewing energy sources such as sunlight, wind, flowing water, the earth's internal heat, and biomass such as agricultural, industrial, and municipal waste.

In recent years, the global agricultural landscape has witnessed a paradigm shift towards more sustainable and ethical practices, with a particular focus on the well- being of animals. One such notable transformation is evident in the egg production industry, where traditional methods are being reconsidered in favour of more humane alternatives. Cage-free farming has emerged as a promising path, not only for meeting the demands of a conscientious consumer base but also for addressing concerns related to animal welfare. Cage-free farming represents a departure from conventional egg production systems that confine laying hens to small, restrictive cages. Instead, it offers an environment that allows hens to express natural behaviors, such as walking, spreading their wings, and nesting.

Most raw feed ingredients used as an energy and/or a protein source in poultry feed are grown, harvested, processed, and transported from outside of the poultry industry. Poultry feed are routinely subjected to contamination from diverse sources which may have a serious consequences on the safety of poultry products. Public concerns over food safety from the food of animal origin is a cause of global concern in the recent years due to problems such as bovine spongiform encephalopathy (BSE), dioxin and melamine contaminations, microbial resistance to antibiotics and outbreak of food borne bacterial infections (food poisoning) (Panda, 2013).

Apart from the heart rate and rhythm, the electrocardiogram also provides information pertaining to the chamber size, i.e. the presence of chamber enlargement in dogs. It can more precisely be evaluated if the P QRS and T complexes are clearly visible without any artifacts. Further, the measurement of the chamber enlargements is only possible when all the segments of the ECG are clearly visible. When the impulse is conducted uninterruptedly from sino-atrial node (SA node) to AV node to the ventricles, the measurement of the amplitude of the complexes (P, QRS, T) is more precise in providing information regarding the presence of chamber enlargement.

Introduction

Aquaculture is one of the rapidly growing industries worldwide with more than 300 different species being cultured. However, majority of aquaculture species are still wild and undomesticated, and the adaption of relevant technologies in the aquaculture sector has been slow. Given that genetically modified stock only accounts for less than 10% of the current global aquaculture production, the aquaculture sector has significant potential to increase production efficiency through selective breeding programmes. Selective breeding is acknowledged as a crucial element in the generation of resource-efficient, sustainable, and profitable aquaculture operations (FAO, 1995; World bank, 2006).

Introduction

The maritime industry, a cornerstone of global trade and commerce, has always been a complex and challenging domain. With the vastness of the world's oceans and the diversity of activities that take place within them, effective monitoring and management of maritime activities are crucial. This is where Systems for Monitoring Vessels come into play. VMS are a form of satellite based surveillance system designed to monitor the location, course, and speed of vessels. They provide real-time data to maritime authorities, contributing to the safety, security, and sustainability of marine operations.

Introduction

Fisheries

For millions of people, fishing and aquaculture continue to be vital food sources, nutrition, money, and livelihood. Fish is a good and economical source of animal protein, offering a solution to the nation's problems with hunger and malnutrition. The Indian fishing industry underwent progressive development throughout the years and developed into a significant socioeconomic factor for the country. India is the third-largest producer of fish and aquaculture, contributing roughly 16% of all inland fish production and 5% of all marine f ish production worldwide, (Department of Fishery, 2023).

Introduction

Traditionally, diagnosing diseases in aquatic animals has involved identifying the infectious agent directly using molecular methods like in situ hybridization or PCR or culture-based methods. Rarely is serological testing used to diagnose f ish. Serological tests have been widely utilized in surveillance programs for terrestrial animals to confirm suspected cases, establish absence of infection or progress toward eradication, estimate infection prevalence, certify individual animals prior to import or export, and show the effectiveness of vaccination.

In recent years several plant pathological laboratories have been using molecular techniques for identification of the fungal plant pathogens isolated from the diseased plants. These are specifically used for the confirmation of the pathogen identified based on their cultural and microscopic characteristics. With the help of fungal genomic studies, not only the genus but also the species of the pathogen is identified based on the genomic sequences available with NCBI, and provide the accurate identification of the fungal isolate. This identification method involves the following steps:a

Introduction

A geographical information system (GIS) is a kind of database that has software tools for handling, analyzing, and presenting spatial data and descriptions of phenomena that have a location component. This system can also involve human users and support staff, procedures and workflows, a body of knowledge about relevant concepts and methods, and institutional organizations in a wider sense. GIS technology is a key part of spatial data infrastructure, which the White House describes as “the policies, technologies, standards, human resources, and related activities that are necessary to acquire, process, distribute, use, maintain, and preserve spatial data.”

Introduction

Global Positioning System (GPS) is a system of satellites and ground stations that provide location and time information for any place on earth, regardless of the weather. GPS is a type of GNSS, which stands for global navigation satellite systems. GPS has many applications in precision farming, such as farm planning, field mapping, soil sampling, tractor guidance, crop guidance, variable- rate applications (VRAs) and yield mapping. GPS helps farmers work in low- visibility conditions such as rain, dust, fog, and darkness. India has its own GPS system called IRNSS or NavIC, which uses about seven satellites. GPS is owned and operated by the U.S. government, specifically the U.S.

Weeds have been a problem to agriculture ever sine man started cultivation. Weed species by and large invade cropped areas and account for large economic losses to the farmer. Weeds are economically more important than insects, fungi or other pest organisms (Savary et al. 2000, 2006). Globally, weeds cause the highest potential loss to crop production (34%), with animal pests and pathogens being less important (losses of18% and 16% respectively). The loss in production due to weeds has been estimated as 5% in developed countries. It is around 10% in developing countries and 25% in least developed countries. (Oerke, 2006)

Rice is the primary food source for half of the Asian population. Nearly 2,000 million in this region obtain 60 to 70 per cent of their calories from rice and its products. Considering the importance of the crop, United Nations General Assembly declared 2004 as the “International Year of Rice” (IYR). In India, the crop covers one-fourth of the total cropped area. About half of the Indian population use rice as their staple food.

Rice based cropping systems are not only important for food security but also for maintaing an ecological balance. Low land rice fields conserve water and prevent runoff .They preserve the sustainability of the ecosystem.

1.1 Introduction

Broadcasting seed and harvesting meagre yields was a common method of ancient agriculture. High use of developed crop varieties, irrigation, chemical fertilizers, pesticides and farm mechanization is the main thrust of modern agriculture. Therefore, modern agriculture is an energy intensive farming system (Khan et al., 2010). Though modern technology based agriculture is achieving success to meet food demand of increasing global population, yet it creates many environmental issues such as loss of soil fertility, salinization and water scarcity.

6.1 Introduction

The birth of modern conventional agriculture coincides with industrial revolution. The identification of N, P and K as critical factors in plant growth led to the manufacture of synthetic fertilizers. While chemical fertilizers and pesticides have existed since the 19th century, their use grew significantly in the early 20 century with the invention of Haber-Bosch method for synthesizing ammonia. The rapid farm mechanization, especially in the form of tractor and combine harvester coupled with science-driven innovative management methods and resources led to the efficiency of enabling outputs of high quality produce per unit area and time.

15.1 Introduction

An endoskeleton is a skeleton that is on the inside of the body of an animal. It is an internal supporting structure composed of mineralized tissue. The endoskeleton develops within the skin or the deeper body tissues. It participates in protection, helps in movement, provides shape and support and stores minerals like calcium. Gerringer et al. (2021) suggested that changes in skeletal structure are non linear and are driven by hydrostatic pressure, other environmental factors and evolutionary ancestry.

46.1 Introduction

Since humans settled and flourished adjacent to the aquatic bodies and therefore f ishes might have attracted their attention. The increasing population has threatened mankind variously amongst which, the most important one is the food problem. Fish being a valuable and easily available source of food can be used to overcome the food problem to a certain extent. Indian rivers are the major source of irrigation systems, drinking water and fish as food. The fish industry of West Bengal and Orissa is some 1500 years old and in West Bengal, every family traditionally has at least one small or moderate-sized pond.

Introduction

To accomplish the objectives of the organisation, the administration often performs a standard set of tasks. Administration is the direction, leadership, and supervision of a group’s actions toward certain common objectives (Newman, 1950). It suggests sincere efforts made to plan and manage human activities in order to accomplish set or desired goals. Organising, leading, and controlling people and resources to achieve predetermined goals.

The 1980s and 1990s saw a few shifts in how we view development. There has been a significant ideological change in favour of privatisation. Since the 1990s, there has been an increase in the participation of the private sector (which deals with agro-inputs, agribusiness, and financial services), non governmental organisations (both local and international), producer groups, cooperatives, and associations, as well as independent and connected to or employed by agri-business/producer associations consultants and ICT (Information and Communication technologies) based services.
