Introduction

In agricultural and horticultural ecosystems greater extent of losses caused by pests includes insect-pests, plant diseases, and weeds and have directly affected the production. Out of these, a group of animals other than the insects also causes the considerable yield losses to agricultural and horticultural crops and commonly known as vertebrate pests such as birds, rodents and mammals. In recent times mammals such as blue bull (Nilgai), wild boars, rodents, porcupine and monkeys has gaining the status of pests and in certain cases a huge damage is being encountered (Rao, et al?, 2015). Among mammals, blue bull and wild boar both has become a serious problem in most of the Indian states for farmers in major agricultural and horticultural crops and resulting into immeasurable damage.

Introduction

Lac, a resinous exudation from female scale insects, has been utilized in India since the Vedic period. Its earliest mention can be traced back to the Atharva Veda, where the insect is referred to as 'Laksha,' and its characteristics and behavior are described. In the renowned Indian epic 'Mahabharata,' there is also a mention of a 'Laksha Griha,' a house made of lac, skillfully constructed by the 'Kauravas' with the help of their architect 'Purocha,' with the malicious intent of setting the 'Pandavas,' their formidable enemies, on fire. The use of lac was well-known to the Greeks and Romans since ancient times. The use of lac was well-known to the Greeks and Romans since ancient times. In Asia, the cultivation of lac insects has a rich history, with indications that it dates back as far as 4000 years in China, where its cultivation coincided with the growth of the silk industry

A judicious use of cytology will be beneficial to the practicing veterinarians as diagnosis is available within a shortest period of time and can decide on proper treatment e.g. TVT can be successfully treated medically without surgical intervention.

Diagnostic Approach in Clinical Set Up

• Clinical investigation
• Clinical pathology
• Necropsy
• Biopsy
• Cytology
• Histopathology
• Electron microscopy
• Fluorescent antibody techniques
• Immunohistochemistry
• Genomic techniques
• Microarray
• Proteomics
• Metabolomics etc.

Location is important

Since, one should recognize whether cells belong to that area and / or not

Basic aim

• To establish an aetiological and/or morphological diagnosis in order to obtain a more accurate prognosis

Salient Points in Cytological Examination

• Cytology is a joint effort between the clinician and cytologist
• Adequate history, clinical signs and methods of collection should be intimated

The Principles of Democracy

Democracy is a form of government in which power is vested in the people, who exercise that power either directly or through representatives. The principles of democracy are a set of fundamental values and beliefs that are essential to the functioning of a democratic society. These principles are intended to ensure that the government is answerable to the people, that individual rights and liberties are protected, and that all citizens have an equal say in decision-making.

The principles of democracy include popular sovereignty, the rule of law, separation of powers, protection of individual rights and liberties, accountability and transparency, pluralism, civil society, and political tolerance. These principles form the foundation of democratic governance and are essential to ensuring that government is responsive to the needs and desires of the people. While the specific implementation of democratic principles can vary from country to country, they are generally seen as essential to a healthy democracy. By upholding these principles, democratic societies are able to promote freedom, equality, and justice, and to provide opportunities for all citizens to participate in the decision-making process.

The fundamental rights enshrined in the Constitution of India are a cornerstone of the country's democratic framework, guaranteeing essential protections and liberties to its citizens. These rights, often referred to as the "heart and soul" of the Constitution, reflect the deep commitment of the framers to create a just and inclusive society. The Constitution, adopted on January 26, 1950, sets forth a comprehensive set of fundamental rights that safeguard individual autonomy, promote equality, and protect against discrimination and abuse of power.

Introduction

In an era defined by unprecedented connectivity and shared global challenges, the assurance of food security emerges as a cornerstone of human welfare and societal stability. At its core, the concept of global food security embodies a delicate equilibrium—wherein the abundant availability, accessibility, utilization, and consistency of nutritious sustenance are assured for all. Yet, this equilibrium remains precariously fragile amidst a confluence of modern predicaments. The imperatives of nourishment transcend mere sustenance; they intertwine with the fabric of public health, economic fortitude, and societal harmony. The imperious need to address food security issues stems from the stark realities it imposes: a profound impact on individual health, the stifling of economic prosperity, and the potential for social unrest. 

Even while the world is ageing, it is not prepared for it. There are 962 million people over 60 in the world as of 2017 with 310.0 million of them living in wealthy countries and 652.2 million in developing ones, according to data from the UN's Department of Economic and Social Affairs (DESA-UN 2017). According to projections, there would be 2.1 billion seniors worldwide by the year 2050 (rich countries: 421.4 million, developing countries: 1670.5 million). By 2030, 80% of the old people in the globe will live in developing countries (DESA-UN, 2015). Elderly individuals in rural developing countries confront challenges such as the lack of pension coverage, work difficulty and high medical costs. Their poor diets and deteriorating poverty raise their risk of chronic illnesses like diabetes, heart disease and cancer (Marshall et al., 2001). 

There are several difficulties involved with consuming and storing microgreens. Addressing low shelf life and putting into practice efficient postharvest management for microgreens provide formidable challenges for researchers. It's critical to comprehend any relationships that might exist between spoiling and human pathogen contamination. Research has indicated that microgreens including basil, lettuce, parsley, melons, and spinach can have infections from pathogens during the seed-to-harvest stage (Alegbeleye et al., 2018). Growing environments that support the growth or transfer of microorganisms, processing techniques that expose the crop to contaminants from people or animals, and physiological traits of the plant that facilitate contact and binding with microorganisms are some of the factors that contribute to this risk (Maluin et al., 2021). Because external fertilizers and manures are applied sparingly, there is little contamination even though microgreens are protected from pests and insects by controlled surroundings.

Conference

A conference is a formal gathering where people come together to discuss, exchange ideas, present research and engage in discussions on specific topics or fields of interest. These gatherings can vary widely in scale, purpose and format, bringing together professionals, researchers, academics, industry experts, or enthusiasts.

Audio conferencing

Its also called Teleconference, which means meeting a group or party via a phone call instead of meeting them physically. In most cases, standard telephone lines and speakerphones are employed. The person who starts the audio conference called the calling party and the people who are attending the calls are known as participants. Technology requirement of the audio conference:

1. Phone/Computer with access to internet connection

Kisan Call Centre (1551)

The department of agriculture and cooperation (DAC) Ministry of agriculture, Government of India launched kisan call centres on January 21, 2004 across the country to deliver extension services to the farming community. It provides information in all major languages through toll-free telephone no 1551 and 1800180 1551 from 6 a.m. to 10.p.m. on all 7 days of a week. on BSNL routes. With a view to monitor the KCC activities a state level monitoring committee (SLMC) has been constituted in each KCC. Presently there are — kccs in the country.

The kisan call centers consists of three levels

Data refers to any collection of facts, observations, measurements, or values that are typically numerical, but can also be qualitative. It's raw material that can be processed and organized to provide context, relevance, and meaning. In its raw form, data may not carry any specific meaning and might appear as a series of numbers, text, symbols, or images.

Types of Data

• Quantitative Data: Numerical data that can be measured and expressed with numbers (e.g., height, weight, temperature).

1. Introduction

Social research refers to study of social trends, dynamics and principles existing between individuals and within societies. Professionals perform social research in order to better understand the social factors that motivate and influence human beings and to analyze how and why humans interact with each other, and thus create new knowledge and theories or tests and verify existing theories. The purposes of social research are manifold and can be classified as exploratory, descriptive, explanatory, community change / action and evaluative.

Expectation from Work and Career

Millennials do not distinguish work from life; for them, both work and life blend into a single entity, and therefore, they do not seek a balance between them unlike previous generations (Meister and Willyerd, 2010). This is precisely why they seek work that has a strong focus on personal fulfilment. Their perception of work is that it is a source of opportunities to strike friendships, learn new skills, and associate with a larger purpose. They derive job satisfaction from this singular sense of purpose - they are also the most socially conscious generation since the 1960s. This social consciousness lends them a sense of validation of their purpose - they wish to see their work making the necessary social impact.

1. Introduction

Technology innovation is characterised by the development and utilisation of novel or enhanced technologies, instruments, frameworks, and procedures that result in noteworthy progressions or discoveries across diverse domains. It entails utilising resources, knowledge, and experience to create creative solutions that address issues, boost productivity, advance the cause, and add value.

In numerous crucial areas, the significance of technological innovation is evident:

In broad perspective, plants and crops of agriculture can be classified mainly based on three criterions namely descriptive, ecological and agronomical. Understanding these basic classifications will help us to study the characteristics of each plant in detail.

Descriptive Classification

In descriptive approach, plants and crops can be classified based on the mode of reproduction, mode of pollination, life span, growth habits and leaf retention property. Sexual and asexual reproducing plants are the two groups based on the mode of reproduction. The sexual reproducing plants are developed from a seed after the union of male and female gametes and asexual plants reproduces through vegetative means and not by male and female gametes.

Food security is a pressing global concern that requires immediate attention. The rapid pace of urbanization and industrialization has resulted in a reduction of available land for agriculture, making it increasingly difficult to meet the growing demand for food. In countries like India, where there is already a shortage of meat, rabbit farming has shown great potential in helping to bridge this gap.

In the rabbit production industry, providing a healthy diet and adequate amount of food every day is crucial for success. Rabbits can only survive and thrive on a diet of forage, so it is important to carefully consider their nutritional needs when planning their feeding regimen.

Some rabbit producers choose to provide basic grains in addition to forages in order to increase the potential productivity of their herd. These grains can be sourced from one's own farm or purchased commercially as concentrated feeds. The type of feed given to rabbits will greatly impact the management of the herd, such as how frequently they need to be rebred.

Introduction

Human beings are the most critical components of an organization. The organization’s survival has improved all the facets contributing to its success. In a competitive world, human resources are sine qua non in an organization. Quality of work life (QWL) is critical for deciding organizational employee- related outcomes. Human resource management has a unique role in any organization. Organizational goals in an organization are achieved through planning, organization, staffing, direction, coordination, and control. 

Introduction

This chapter reviews literature related to the current study on Quality of Work Life (QWL). Scrutiny of the available literature is of great value in gaining insight into the research problem. It is beneficial for strengthening the research problem. As there are fewer studies on QWL in the university libraries in Kerala, the works reported in other places were also reviewed. Hence, the available studies related to the topic are exhaustively reviewed. The review covers studies on the subject made at the regional, national, and international levels.

Introduction

It has been proved that libraries play a crucial role in education. Libraries have been collecting, preserving, and organizing knowledge since time immemorial. In the age of virtual information, libraries have been reinventing themselves as accessible and engaging learning spaces. Libraries existed in India during the ancient and medieval periods. The library is the primary requirement of the university. University libraries have a paramount role in developing university education in the country. The present chapter highlights the historical development of libraries, committees, and commissions on university libraries in India.

At a compound annual growth rate (CAGR) of 7.6%, the global poultry industry expanded from $352.02 billion in 2022 to $378.84 billion in 2023. Global production of chicken meat was projected to reach 103.4 million metric tons in 2023, primarily as a result of rising output in China, India, Brazil, and the US. India is currently the world’s second-largest egg producer (138.3 billion eggs in 2022–2023), trailing only China. It is also the world’s fifth-largest broiler producer (producing 4.99 metric tons (MT) in 2022–2023), behind China, the United States, Brazil, and the Russian Federation.

The poultry industry in India is experiencing rapid growth, with meat production and egg production increasing by 5.13% and 6.77%, respectively, in 2022-2023 compared to the previous year (BAHS, 2023). Numerous factors and challenges impact poultry production on a global scale, such as intense international competition, evolving consumer attitudes toward food safety, animal welfare, and environmental conservation. Poultry commonly harbor infectious diseases that can also affect humans, with many of these zoonotic diseases having reservoirs in mammalian species other than humans, adding complexity to their management.

Poultry holds significant value as it provides essential protein, vitamins, and mineral nutrients, including eggs and chicken meat.Poultry is a significant source of organic fertilizer and generates income and employment for millions of farmers and other poultry cultivators. The bigger and richer the industry, the more problems they face.Infectious diseases transmitted by flies, majorly house flies (Musca domestica) and other insects are the primary concern for poultry farmers on their farm. The threat of flies is a major problem worldwide wherever poultry farming is an important economic activity.In livestock and medical treatments, flies are significant pests that can cause irritation, spoilage of food, and serve as vectors for various pathogenic organisms. They are also highly destructive.

Introduction Concerns about how future generations can sustainably produce more food are felt everywhere. The use of chemicals, nutrient leaching, and the conversion of natural land to agriculture are all important problems that have a negative influence on the environment and natural resources. The usage of nitrogen in artificial fertilizers has increased 20 times over the past 20 years, severely eutrophicating water bodies. Therefore, it is believed that the only approach to increase water and nutrient efficiency, as well as reduce waste, is to close the loop between crops and animals. A further step towards sustainability would be to use less land (Datta, 2016).

Introduction

Aquaculture uses a variety of chemicals for a number of functions, including sediment and water management, improving natural aquatic productivity, transporting living organisms, creating feed, manipulating and enhancing reproduction, promoting growth and health, processing, and adding value to the finished product (GESAMP, 1989). Aquatic systems are thought tobe suitable places to recycle and dispose of hazardous and sewage wastes, with any excess being drained into the ocean. To fulfil the demands of the ever-increasing population, the water resources are overused for potable supplies, irrigation, industry, and thermal generating plants, which drastically diminishes their assimilative capacity.

Introduction

Currently, one of the most serious problems facing the world is environmental degradation. Multiple technological tools are required for the detection and remediation of pollutants. Environmental pollution is steadily rising and has an adverse effect on every living organism, including humans. Microorganisms and plants have biosynthetic pathways for the accumulation or breakdown of environmental contaminants from soil and water can minimise it. Because natural microbes and plants lack genetic components, they are less able to absorb or digest contaminants, and as a result, they are currently released at high levels. Plants, animals, and/or microbes are utilised as biological indicators to detect pollution in a particular ecosystem (Zaghloul et al., 2020).

Introduction

Seaweed, a diverse group of marine algae, thrives in a variety of aquatic environments across the world’s oceans. Found in both shallow coastal waters and deeper offshore regions, seaweed plays a crucial ecological role in marine ecosystems. It attaches itself to rocky substrates, sandy seabed, or even other marine organisms, utilizing the rich nutrients present in seawater for growth. Seaweed populations are influenced by factors such as water temperature, light availability, and nutrient levels.

Introduction

The oceans account for 72% of Earth's total surface area and sustain the lives of billions of people. The oceans contain an abundance of both living and nonliving materials, and their depths contain aspects that have yet to be discovered. The oceans significantly affect our everyday weather and climate patterns, as well as the quality of the air we breathe and the water we drink. At this time, our understanding of the oceans is limited to relatively shallow depths. Exploration of the deep sea, which requires specialized modern equipment that is not commercially accessible at the moment, is necessary due to global security concerns involving oceans.

Introduction

Biosecurity includes a set of standard scientific measures, adopted to exclude pathogens from culture environments and hosts and, more broadly, limit the establishment and spread of pathogens” (Mohan et al., 2003; Moss et al., 2012). Biosecurity is an emerging concept, and the phrase is changing as usage differs across nations and among different professional groups. A holistic approach to addressing biological risks associated with food and agriculture is what is widely referred to as "biosecurity.

Introduction

Over the past two decades, seafood consumption and popularity have gradually increased. However, creating high-quality items necessitates paying close attention to the product's quality and safety as well as creating new products employing modern technologies. Through a variety of modern biotechnology advancements such as biomagnetism, biosensors, biomarkers, and bioassay methods are used to analyze and assess the quality of various seafood by f inding concentrations of compounds including allergens, nutritional and non-nutritional components, antioxidants, and the presence of microbial contaminants, biotoxins, and other contaminants significantly effective in food safety evaluation.

Introduction

Fertilizers are natural or man-made compounds applied on the plant ,soil or water for enhancement of natural soil or water nutrients for improvement of growth , fertility of soil (Edgerton 2009) or water. These make accessible vital macro-nutrients (nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium) together with various micronutrients (zinc, copper, iron, boron, and molybdenum) to plants (Alley and Vanlauwe 2009) and animals.

The pathogen forms a large number of acervuli on the infected parts. The conidiophores are slightly curved, short, and club-shaped. The conidia are hyaline and falcate, borne singly on the conidiophores. Numerous black colored and thick-walled setae are also produced in acervulus. In culture, most isolates produce cottony, fluffy, or suppressed colonies (Fig. 7.1).

Introduction

We use our five senses to perceive the world around us. Some senses, like touch and taste, need contact with the objects. But we get most of our information about the environment through sight and hearing, which do not need close contact with the external objects. In scientific terms, we are doing remote- sensing all the time. Remote- sensing is the process of recording/observing/ perceiving (sensing) objects or events from a distance. Remote- sensing is a way of monitoring and detecting the features, usually physical, of a specific area by measuring its reflected and emitted radiation (usually from satellite or aircraft).

Introduction

Spectral signature: A spectral signature is the unique pattern of reflection and emission of a target at different wavelengths. This difference helps to classify remote sensing images based on the spectral signatures of different objects.

Electromagnetic (EM) spectrum: The EM spectrum is the range of all types of EM radiation. Some examples are visible light from a lamp, radio waves from a radio station, microwaves, infrared light, ultraviolet light, X-rays, and gamma rays.

Spectral response patterns: A spectral response pattern is the amount of energy that an object reflects or emits at different wavelengths. It shows how the object interacts with the EM radiation.

Introduction

Crop discrimination is the process of using remote-sensing technologies to identify and characterize different types of crops based on their electromagnetic behavior at different wavelengths. Each crop has a unique spectral signature that reflects its response to the incident radiation. However, the spectral signature can also vary depending on the season, the angle of the sensor, crop’s features, illumination intensity, weather phenomenon, and topography among other external factors (Parida et al., 2023).

Introduction

To address the escalating food demands of the global population, a transformation in the agricultural sector is imperative (Velten et al., 2015; Lampridi et al., 2019). The current overdependence on finite resources is leading to their overexploitation, largely due to irresponsible usage (Velten et al., 2015; Lampridi et al., 2019). By adopting a site-specific approach, farmers can apply inputs only where they are necessary in the field (Velten et al., 2015; Lampridi et al., 2019). This method can enhance output, decrease labor costs, and mitigate the environmental damage caused by excessive input use (Velten et al., 2015; Lampridi et al., 2019).

Introduction

Nanopesticides are pesticides that use nanomaterials or nanotechnology to improve their effectiveness and safety in agriculture. Nanomaterials are materials that have at least one dimension between 1 and 200 nm. Nanomaterials have different properties than their bulk counterparts, such as higher surface area, reactivity, and mobility. Nanopesticides can be formulated in various ways, such as nanosized active ingredients, molecular active ingredient nanocarrier complexes, or active ingredients encapsulated or coated by nanomaterials (Deka et al., 2021; Xu et al., 2022).

Introduction

Crop models can be broadly classified into two categories: dynamic or process-based crop simulation models (CSMs), and reduced form statistical models. Since simulation models are based on various plant-related processes, they develop or alter in tandem with plant growth (Chetty 2009); as a result, they are inherently nonlinear (Olmstead 2009). To run, calibrate, and validate, they require a significant amount of date input. However, statistical models are helpful in situations where there is a lack of data because they describe the relationships between a subset of variables while keeping the others constant. (Chetty 2009).

India is basically an agrarian economy where 57.8% of rural households are engaged in agriculture (Situation Assessment Survey of Agricultural Household, 2021). 48.9 per cent of the Indian work force is employed in the agricultural sector, (ILO, 2016). The estimated Indian population for the year 2050 is 1.7 billion which will raise our food demand to ∼400 million tonnes (Rao et al., 2018). In this context, Indian agricultural production system will have to take up the challenge to feed l7.5% of the global population with only 2.4% of land and 4% of the available water resources at its disposal.

Major advantage of chemical herbicides over other methods of weed control is its ease of application, which saves the cost of labour for the farmer. Effectiveness of herbicide depends on how long it remains in active form in the plant /soil. The form in which any herbicide is available in the market is known as herbicide formulation. The technical active ingredient (ai.) of the herbicide is converted to a formulations so as to improve easiness of handling, retention on leaf surface, absorption and movement in the plant. Herbicides are available in different formulations.

When a herbicide is applied to the soil, it is subjected to various interactions with soil and surrounding environment which ultimately determines its persistence. Dissipation of these compounds from soil system is by three main processes viz., physical (volatilization, leaching and runoff), chemical (photochemical decomposition, adsorption by organic and inorganic colloids and chemical decomposition) and biological (microbial decomposition and plant uptake)

Indian tea has a global reach being the second largest tea producer in the world. Indian tea is one of the finest in the world. Darjeeling tea is the first product to get a geographical indicator tag in India. 83 % of the tea produced in India is from Assam and West Bengal and 17% from the south Indian states of Kerala, Karnataka and Tamilnadu. Weeds are a major problem in tea gardens.

3.1 Introduction

Rice is the main staple food for most of the world’s population and plays a key role to maintain food security of many countries. More than 90% of the rice production globally comes from Asia and also more than 90% of rice consumption is done in Asia (IRRI, 1997). In Asia, more than two billion people get almost 60-70 percent of their daily energy requirement from rice and its products (Yogeswari and Porpavai, 2018). As for India, since independence the country has witnessed a remarkable progress in rice production.

7.1 What is Soil Moisture Conservation Technique?

In situ soil moisture conservation means capturing rain water and retaining it in soil for utilization by plants for better growth and increase in biomass and grain yield. This is achieved through rain water harvesting on farm or field where crops are planted to get benefit from the conserved rainwater. It reduces rainwater loss through runoff and increases rain water infiltration time, thereby increasing the amount of rain water in the soil that will be useful for crop production.

17.1 Introduction

Mechanical irritability is a general phenomenon exhibited by a cell. Apart from a general response to mechanical deformation, there are specialised receptors distributed internally as well as externally that act as mechanoreceptors. It includes the following:

1. Algesireceptor (Nociceptors): For pain.

2. Georeceptor: A gravity and acceleration receptor.

3. Phonoreceptor: Used for vibratory contact and sensation of hearing and also for equilibrium.

Fishes are generally unisexual and reproduce by several methods. Some families (Sparidae and Serranidae) are hermaphrodite also. Alz (1964) reported that in certain species, hermaphrodism becomes a normal way of life. In hermaphroditic f ishes, self-fertilisation is a common process. Parthenogenesis could have been produced experimentally (Austin and Walton 1960). There maybe a few secondary organs that increase reproductive fitness. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm are released; the sex of a fish can often be determined by the shape of its papilla.

35.1 Introduction

Age and growth studies are vital aspects of modern fisheries because this information is pivotal for fish population and management policies.

Age and growth are important factors in the study of the natural history of fish. Age determination is an ancient practice that aids in systematic studies of fish and f isheries. Age denotes the activities of the organism about its size, whereas growth can be defined as an increase in any dimension of an organism from time or age until maturation. A fish ages as it grows, and vice versa. Fish age determination is important to marine resource management.
