10.1. Co-operative marketing

Private agencies dominate Indian food grains trade.

High marketing charges and prevalence of malpractices.

Progress of regulated markets is not uniform in all areas.

Need for strengthening co-operative organization in marketing of farmers produce and supply inputs at right price and time.

Moisture Content
 
Two maximum moisture levels are provided to meet different climatic conditions and marketing practices. Lower values in the first column are suggested for countries with tropical climates or when long-term (more than one crop year) storage is a normal commercial practice. The values in the second column are suggested for more moderate climates or when other short term storage is the normal commercial practice.

Data collected by using different data collection methods remain meaningless until it is screened, cleaned, coded, analyzed and summarized. Data cleaning and screening mostly come under the purview of statistical logics and techniques hence not dealt with in this practical guide. Since these aspects will be dealt by the statistical experts from the allied statistical wings. Presuming that students are aware about data cleaning and screening, we will proceed further with data coding.

Cold chain logistics refers to the technology and processes that ensure the safe transportation of temperature-sensitive goods throughout the supply chain. It is deeply rooted in scientific principles, assessing the relationship between temperature and perishability to maintain product integrity.
Any item categorized as “perishable” typically requires cold chain management. This includes food products such as meat, seafood, and fresh produce, as well as medical supplies and pharmaceuticals.
Although, modern transportation is a relatively recent development, the  practice of moving temperature-sensitive products dates back to the late 1700s when the British used ice to preserve fish. By the late 1800s, ice was widely used to transport perishables. Dairy products were shipped from rural areas to urban markets. Cold chain technology has long been a crucial component of global trade and will continue to play a vital role in the future.
COLD CHAIN LOGISTICS
A cold chain is a specialized supply chain designed for handling perishable and temperature-sensitive goods, commonly referred to as cool cargo. These include fresh produce, meat, dairy, seafood, chemicals, pharmaceuticals, flowers, wine, and other delicate products. To preserve the quality and integrity of these perishable items, specific lowtemperature conditions must be maintained throughout the supply chain. Certain products require refrigeration; others must be kept frozen, while some demand extreme conditions—often referred to as an ultralow chain or deep freeze. Any failure to maintain the appropriate temperature can result in product spoilage, compromising safety and quality, and ultimately leading to significant financial losses.

Soil testing identifies various constraints in soil that limit crop production. Fertilizer recommendation and soil management practices to be adopted are based on the soil test report. Soil testing starts with collection of soil samples from the field
and ends with interpretation of soil test results leading to necessary recommendations for increasing crop production.

This chapter explains how representative soil samples should be collected, labelled, transported and prepared for analysis. It identifies essential sampling equipment, including spades, khurpis, augers, trays, sampling bags, markers and polythene sheets. The recommended procedure involves dividing land into uniform sampling units, collecting soil from several well-distributed locations and combining these portions into a composite sample. The chapter describes V-shaped sampling cuts, suitable sampling depths and sample reduction through quartering. It also lists the field information that should accompany each sample. Procedures for air-drying, grinding, sieving and mixing samples are presented, together with precautions for avoiding unusual areas and contamination.

Water colour is consequences of the plankton, humus, metal ions (iron and manganese), weeds and peat materials, presence in water. Iron oxides cause reddish color whereas Manganese oxides causes brown or brackish colour in water. Water colour of an aquatic body also indicates the density of planktons. Brownish colouration without any foul smell is an indication of good growth of zooplankton. Phytoplankton or algae are usually green in colour and these green alage in large quantities turn the green color of water. Water color suggests plankton or other aquatic life growth, clear and transparent colour of water indicates low and poor growth of plankton. Brownish green to greenish brown colour of water indicates well for aquaculture.
Principle
Natural waters colour comprising yellow-brownish in appearance. It has been observed that potassium chloroplatinate (K2PtCl2) tinted with small amounts of CoCl2 yield colours that are very much like the natural colours of water. 1 mg/L of Pt (K2PtCl6) produces a standard 1 unit of colour. The intensity of colour increases as pH rises. For this reason recording pH together with colour is advisable.

To achieve maximum possible irrigation efficiencies, there are two approaches.

Modernization of conveyance system down below the reservoirs upto government controlled outlet. Involves mainly the construction and maintenance of head sluices, main canals, branch canals, and distributaries (Modernization of supplier’s side or system level development works)

Modernization below the government controlled outlets upto the drains (Modernization of user’s side or farm level development works). Also known as On-Farm Development Works (OFD).

In the Asian and Pacific ‘region, it is China alone which produces the largest quantities of agricultural waste and also crop residues. This is followed by India. From the production of rice, corn and wheat alone 587 million tons of residues are generated per year in China. Maheshwari (2014) has surveyed the proportions of waste that Malaysia generates from the production of rice, palm oil, rubber, coconut and forest products. In Myanmar the crop waste and residues constitute about 4 million tons per year out of which more than half constitutes rice husk.

18.1 Introduction

The commercially available water quality simulation models with various dimensions (1D, 2D and 3D) and database software designed to quantify movement and concentration of contaminants in lakes, streams, estuaries, and marine environments. The following water quality models were described below (Table 18.1).

18.2 Environmental Fluid Dynamics Code

The Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling system, which includes hydrodynamic, sediment-contaminant, and eutrophication components. It has been applied to over 100 water bodies including rivers, lakes, reservoirs, wetlands, estuaries, and coastal ocean regions in support of environmental assessment and management and regulatory requirements. IT is a state-of-the-art hydrodynamic model that can be used to simulate aquatic systems in one, two, and three dimensions. It has evolved over the past two decades to become one of the most widely used and technically defensible hydrodynamic models in the world. It uses stretched or sigma vertical coordinates and Cartesian or curvilinear, orthogonal horizontal coordinates to represent the physical characteristics of a waterbody. It solves three-dimensional, vertically hydrostatic, free surface, turbulent averaged equations of motion for a variable-density fluid. Dynamically-coupled transport equations for turbulent kinetic energy, turbulent length scale, salinity and temperature are also solved. The model allows for drying and wetting in shallow areas by a mass conservation scheme.

11.1. Central Silk Board

Established in 1948 at Bangalore under administrative control of Ministry of Textiles.

Vegetation is a key component in hydrologic modeling. Transpiration, a component in hydrologic cycle, is contributed by vegetation. Most of the hydrologic model thus includes vegetation as a parameter. For accurate and appropriate model output, first requirement is good quality data. Most of the time, the data on vegetation is confusing, as in literature various researcher have used different values for common vegetation parameters. Here some common parameters of some important crops, which yield good quality results, are given.

Kharif crops are generally sown during last week of May and first week of June, while rabi crop are sown during last week of November and first week of December. But this period will vary from region to region as well as depends on variety of crop.

Communication Gap
A communication gap occurs when there is a breakdown in the communication process, leading to misunderstandings, incomplete information transfer, or misinterpretation of messages. It can happen between individuals, groups, or organizations, and has significant impacts on relationships, productivity, and decision-making.
Reasons for Communication Gaps
Several factors contribute to communication gaps. These reasons can be categorized into three broad areas: individual, organizational, and technological.

3.1. Communication

Leagans (1961) refers as process by which two or more people exchange ideas, facts, feelings or impressions in ways that each gains a common understanding of meaning, intent and use of messages.

Communis is Latin word - meaning common.

Act of getting a sender and a receiver tuned together for a particular message, or a series of message.

Winfield (1957) refers as whole learning process; encompasses

 Objectives
• Understand the meaning of the communication process.
• Learn the various types of communication.
• Explore different models of communication.
• Analyze how communication flows in different contexts.
Meaning of Communication Process
The communication process refers to the systematic steps through which a message is conveyed from a sender to a receiver. It involves the transmission of information through a medium, with feedback confirming whether the message has been received and understood correctly.
Elements of the Communication Process
The communication process consists of the following elements:
• Sender: The person or entity initiating the message.
• Message: The content or information to be communicated.
• Encoding: The process of converting the message into symbols, language, or signals that can be understood by the receiver.
• Medium/Channel: The pathway through which the message is transmitted (e.g., face-to-face, email, phone).
• Receiver: The person or entity for whom the message is intended.
• Decoding: The process by which the receiver interprets and understands the message.
• Feedback: The response of the receiver that indicates whether the message was understood

Abstract

During present investigation a comparative study was done to see the effect of storage on physical properties of tomatoes (Lycopersicon esculentum Mill) packed in HDPE and stored under ambient temperature. Four varieties of tomatoes taken for current investigation were Badshah, Himshikhar, NS-524 and Raja. From the studies it was clear that TSS increased gradually during storage duration for entire tomato varieties due to loss of some moisture from tomatoes. Variety NS-524 shows maximum shrinkage among all during observation period.

Introduction

Droughts are considered to be a significant environmental disaster and have captured the attention of various experts, including environmentalists, ecologists, hydrologists, meteorologists, geologists, and agricultural scientists. These natural calamities are known to occur in almost all climatic zones, regardless of whether they are high- or low-rainfall areas. Generally a decrease in the amount of precipitation received over an extended period such as a season or a year, is the primary cause of droughts. However, other factors such as high temperatures, strong winds, low relative humidity, and characteristics of rainfall (e.g., intensity, duration, onset, and termination) also play a crucial role in their occurrence. It’s important to distinguish a drought from aridity, which is a permanent feature of a climate and is limited to low rainfall areas (Wilhite, 1992). A drought is a temporary phenomenon and can last from a few months to several years. Some people often mistake droughts for heat waves, but Chang and Wallace (1987) highlighted the fundamental difference between these two events. A heat wave typically lasts for a week, while a drought can extend for several months or even years. When a heat wave and a drought coincide, it can lead to dire socio-economic consequences.

ABSTRACT

Academic libraries are unique, essential and strategic hubs inside our social cloth which are advanced primarily based totally at the requirements of the times, to help people in the purchase of good enough facts that could allow them to decorate their information, for the development in their wellness and that of the society at large. To attain their goal, they ought to generate, filter, control and diffuse correct and well timed human information which have been harvested and documented; for the purpose of enriching the highbrow needs in their clients. Like every other kind of library, academic libraries are growing organisms. Justification to the above statement has been captured aptly in the classic book of Ranganathan (1931) entitled ‘Five Laws of Library Science’; detailing the principles of the library profession. The philosophical postulation of Ranganathan’s fifth law is a classical position that offers much strength and support for the need to adequately plan for the best strategies to exhibit in academic library environments in order to provide effective services. In other words, the fore-stated law by Ranganathan has already signaled that academic librarians must be ready at all times to effectively satisfy the diverse, complex and ever-increasing information needs of their users from the explosive available information resources that spring on a daily basis. As such, addressing this issue would require a holistic management approach by academic libraries that must be internally efficient and externally effective.

INTRODUCTION
The engine is the core of a tractor, providing the essential power required for all its functions. Typically, a tractor engine is a four-stroke internal combustion engine that operates on diesel, although some models may use gasoline. The engine consists of several integral components that work together to generate power and ensure smooth operation. These parts include the cylinder block, which houses the cylinders where fuel combustion occurs; the pistons, which move within the cylinders to convert the energy from combustion into mechanical motion; and the crankshaft, which transfers the piston’s motion to the transmission. The valve system regulates the intake of air and fuel, as well as the exhaust of gases, ensuring efficient combustion. The fuel system, made up of the fuel tank, pump, and injectors, supplies fuel to the engine, while the cooling system, typically water-based, prevents the engine from overheating. Furthermore, the lubrication system ensures proper lubrication of all moving components to reduce friction and wear. The starter motor and battery are responsible for initiating the engine’s operation, and the exhaust system directs exhaust gases away from the engine. Together, these components enable the tractor to generate the power needed for a wide range of agricultural and industrial tasks.
A tractor engine is designed to deliver high torque at low speeds. It is an internal combustion engine that primarily operates on diesel, compressing and burning the fuel to generate mechanical motion. Due to the engine’s complex structure, it is composed of several key components. The following list outlines the major parts that make up a tractor engine:

Theory

Area computation is an important part of surveying. The term ‘Area’ is meant the projected area on a horizontal plane. The area is computed from the following methods: (i) Graphical method (ii) Instrumental method and (iii) Use of formulae. In graphical method, the area can be computed by dividing the whole area either into triangles or squares. The area of individual triangle is computed from base and the altitude and summation of individual area gives the total area. A tracing paper is divided into number of small squares is placed over the plan. The number of complete squares within the boundary is counted. The squares more than half are counted as full squares and those less than half are neglected. The total number of squares multiplied by the area of each square gives the total area of the field. In instrumental method, the planimeter is used to measure the area of a plotted plan. In use of formulae, computation of area by formulae depends on the shape of the field.

Introduction

In recent decades, severe weather and climatic occurrences have become more frequent, affecting human populations across the globe. These changes are caused, in part, by anthropogenic climate change. Vulnerable communities are particularly affected by these rapidly changing patterns, which can have catastrophic consequences. To mitigate the impact of climate change, communities must have access to accurate and up-to-date climate information. Weather predictions, from short-term forecasts to long-term scenarios based on data from previous decades and centuries, can provide valuable information to socioeconomic sectors that are vulnerable to climate change. Climate services offer scientifically-based data and forecasts that can assist decision-makers in managing the risks of climate variability and change. Globally accepted indices generated from daily temperature and precipitation data can indicate the more severe features of climate change. These indices are developed and analyzed by the CCI/WCRP/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI) and have made a significant contribution to the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports.

Introduction

Agriculture has played an important role in the global economy in recent years. The further growth of the population is leading to a gradual decrease in the area of the agricultural land and further growing stresses on the farm system. Agricultural food production methods are rising in demand for successful and healthy. Innovative sensoring and motive technologies and advanced information and communications systems and Artificial Intelligence must supplement conventional agricultural management methods to speed up farm productivity growth more accurately, thereby promoting the production of high-quality and high-performance agriculture. Computer vision monitoring systems have become valuable tools in farm operations over the past decades, and their use has increased significantly.

What is Computer Vision?

Computer vision can be characterized as a field of AI for extracting information from digital images. The type of data obtained from an image may be different from recognition, navigational space measurements or applications of increased reality.

The applications of computer vision can also be described. Computer vision builds algorithms that recognize and use the quality of pictures for other purposes.

Introduction

A solar collector, the special energy exchanger, converts solar irradiation energy either to the thermal energy of the working fluid in solar thermal applications, or to the electric energy directly in Photovoltaic (PV) applications. For solar thermal applications, solar irradiation is absorbed by a solar collector as heat which is then transferred to its working fluid (air, water or oil). The heat carried by the working fluid can be used to either provide domestic hot water/heating, or to charge a thermal energy storage tank from which the heat can be drawn for use later (at night or cloudy days). Solar collectors are usually classified into two categories according to concentration ratios: non-concentrating collectors and concentrating collectors. A non-concentrating collector has the same intercepting area as its absorbing area, whilst a sun-tracking concentrating solar collector usually has concave reflecting surfaces to intercept and focus the solar irradiation to a much smaller receiving area, resulting in an increased heat flux so that the thermodynamic cycle can achieve higher Carnot efficiency when working under higher temperatures.

Most of the scientific research studies –except few descriptive survey research studies–will have one or more hypotheses to be tested as a part of study. Hypothesis is a prediction intended to be tested in a research study (Aron, Coups, and Aron, 2012). Hypothesis is the guide which directs the purpose and process of research by indicating the dependent and independent variables to be observed, extraneous variables to be controlled and the active variables to be manipulated.

Reliability deals with the dependency, consistency, stability, predictability and accuracy of the research data. In our day to day life, when we say that a person is reliable then it means his behaviour is predictable, his behaviour (the way he behaved in past, he is behaving now and the way he will behave in future) will be consistent and he is dependable. On other hand an unreliable person’s behaviour is unpredictably variable and he cannot be depended upon.

Term ‘Scientific research’ is too broad to be explained by using one or two definitions. One should go through the different expert views about scientific research in order to internalize the concept of scientific research. In essence a scientific research is characterized by its rigor, testability, replicability, precision, confidence, objectivity, generalizability and parsimony.

Research: Uma Sekaran (2006) defined research as an organized, systematic, data-based, critical, objective, scientific inquiry or investigation into a specific problem, undertaken with the purpose of finding answers or solutions to it.

Valorization refers to the process of enhancing the value or price of something, often through government intervention or by recognizing its inherent worth. It can involve stabilizing prices, creating value from overlooked materials, or promoting the importance of a particular concept. In the context of waste management, valorization specifically denotes the conversion of waste materials into useful, marketable products using innovative and sustainable methods. It plays a critical role in waste-to-value processes by shifting the focus from traditional waste disposal to resource recovery, aligning with the principles of a circular economy. Rather than viewing waste solely as an environmental challenge, valorization recognizes it as a valuable resource. When processed properly, waste can yield energy, materials, or bio-based products. Common techniques include composting, anaerobic digestion, pyrolysis, and recycling, which are used to extract value from agricultural, industrial, and municipal waste. The primary goals of valorization are to reduce environmental pollution, generate economic returns, promote sustainability, and lessen reliance on virgin raw materials. By driving innovation in biotechnology, materials science, and engineering, valorization supports the growth of eco-friendly industries and fosters long-term environmental responsibility. Ultimately, it transforms waste management into a proactive, profitable, and sustainable practice.
Meaning and Definition
Valorization refers to the process of enhancing or increasing the value of a material, product, or resource—particularly one that is considered waste or of low economic worth—by converting it into a more useful, marketable, or environmentally beneficial form.
Definition
Valorization is the act or process of transforming waste materials, by-products, or low-value resources into valuable products, energy, or materials through physical, chemical, or biological methods. Its goals are to reduce environmental impact while simultaneously generating economic and social benefits. As such, valorization is a fundamental principle of the circular economy and sustainable development.

Introduction
Understanding the concepts of technology transfer, licensing, and commercialization is crucial as it plays an important role in understanding how scientific discoveries leads to generation of new technologies further making them the impactful solutions that benefit industries and society. In the context of Indian HEIs, this especially important because a large volume of impactful research often remains underutilized due to limited commercialization channels. This chapter explains the terminology, essential components of technology transfer, outlines its significance for the innovation ecosystem. It also outlines the evolution of India’s technology transfer ecosystem, and emphasizes while understanding its potential to boost India’s economy, encourage entrepreneurship, and strengthen global competitiveness. From initial idea to a market-ready product is complex and multiphased process. The stepwise process is shown in Figure 1. It highlights a structured pathway consisting of five core phases: Idea/Concept, Technology development, Intellectual Property (IP) rights, Technology transfer, and Technology commercialisation.
Phase 1: Idea/Concept stage
This process of technology transfer starts with the Idea/Concept phase, where an invention is created. Each phase plays an important role in transforming raw scientific knowledge into innovative solutions that benefit society and generate economic value. In this phase breakthrough ideas emerge, within labs. Researchers explore and develop initial proof-of-concept or prototypes to validate their ideas. At this stage, the focus is primarily on knowledge creation rather than commercialization. This pathway of technology transition is summarized in Figure 1.

Whenever we design a scientific study it is designed in a specific contextual background to solve one or another scientific problem. Subsequently it also involves a set of variables/phenomenon operating in a particular context, set of relationships among these variables and the conditions under which they operate. Certainly, to address an unsolved scientific problem we need to carry out research by employing well defined research methodology and have an idea about possible outcomes.  For example when a extension scientist is asked to study the impact of a novel programme, he needs to understand the background and the context under which the programme was introduced, what are the developmental inputs given under the programme, to whom, when (variables), with what purpose (context), what kind of impact he/she is supposed to investigate (presumed relationship), what methods he is going to use to investigate the impact of developmental programme (research methodology) and what are the possible outcomes of the investigation and how programme interventions are related to the outcome (relationship).

Large Language Models have fundamentally changed natural language processing and expanded the role of artificial intelligence across software engineering, healthcare, education, business and scientific research. This concluding chapter synthesizes the major technological, operational and societal themes addressed throughout the book and develops a roadmap for next-generation AI models. It considers the continuing evolution of model architectures, training methodologies, multimodal capabilities, real-time inference and specialized applications. At the same time, future AI development must address privacy, fairness, transparency, accountability, security, computational cost and environmental sustainability. The chapter emphasizes that LLM development cannot be viewed solely as a race toward larger models; future systems must also become more efficient, adaptable, interpretable and responsible. Emerging directions include self-improving systems, real-time reasoning, multimodal intelligence, domain-specific models and increasingly autonomous AI agents. Lifecycle governance, continuous evaluation and human oversight will remain essential as models become more deeply integrated into society. The roadmap therefore calls for collaboration among researchers, developers, industry, policymakers and users to create AI systems that combine technological capability with safety, sustainability, human values and social responsibility.

7.1. Summary

The present research had been carried out to study the social ecology of arsenic contamination in groundwater; factors, perception and impact on life and livelihood of the selected village of West Bengal and in the end the comparison is made. The study had been conducted at village Mitrapur in the Haringhata block of West Bengal. A pilot study was conducted to understand the area, its people, institution, communication and extension system of these states.

An exhaustive list of respondents was prepared critically with the help of some villagers. From the list, 70 respondents from the village were selected for the study through a non-random snowball sampling method. The primary data were collected with the help of a structured interview schedule by following the personal interview method. The secondary data were collected from our departmental library, internet, Department of Agriculture, West Bengal, Bidhan Chandra Krishi Viswavidyalaya etc. for establishing the conceptual framework of the study.

Three types of Issues are Covered in this Study

• The influence of social, cultural, and/or economic variables on how drinking water poisoned with arsenic affects people’s life, notably their health (for example socio-economic patterns of illness and social),

• Social factors influencing people’s response: especially in relation to other priorities, perceptions of arsenic, and social roles and relationships.

Food preservation has evolved from traditional household practices to an interdisciplinary field incorporating microbiology, biochemistry, engineering, biotechnology, packaging, nanotechnology and digital intelligence. The book demonstrates that food stability can increasingly be achieved without excessive reliance on synthetic chemical preservatives. Effective preservation requires control of microbial growth, enzyme activity, oxidation, moisture, temperature and environmental exposure while protecting sensory and nutritional quality. Traditional practices remain scientifically valuable, while thermal, non-thermal, biological, packaging and digital technologies offer new possibilities. Future food systems will depend on carefully designed combinations of these approaches to improve safety, shelf life, sustainability, traceability and consumer acceptance while overcoming cost, regulatory and scalability challenges.

Objectives
• Provide a comprehensive understanding of consonant sounds in English.
• Familiarize learners with the International Phonetic Alphabet (IPA) symbols for consonant sounds.
• Enhance pronunciation skills through the correct articulation of consonant sounds.
• Enable learners to distinguish between voiced and voiceless consonants
• Equip learners with practical examples to apply phonetic knowledge in speaking and listening effectively.
Introduction
Consonant sounds are an integral part of spoken English, contributing significantly to the clarity and intelligibility of speech. Unlike vowel sounds, consonants are produced with a degree of constriction or closure in the vocal tract, which modifies the airflow. These sounds can be categorized based on various parameters, such as their place of articulation, manner of articulation, and whether they are voiced or voiceless.
The International Phonetic Alphabet (IPA) provides a standardized set of symbols to represent these sounds, ensuring a consistent approach to learning pronunciation. Understanding consonant sounds and their IPA symbols allows learners to decode and produce words accurately, improving their overall communication skills.

Root harvesting equipment is useful in harvesting root crops such as potatoes, carrots, beets, turnips, onions, sweet potatoes, and other underground crops. These machines are designed to dig, lift, and separate the roots from the soil while minimizing damage to the crops. Root harvesting equipment can vary in size and design depending on the crop being harvested and the scale of the operation. Here’s an overview of the different types of root harvesting equipment and their features:
VARIANTS OF ROOT HARVESTING EQUIPMENT
Potato Harvesters
• Two-Row Potato Harvesters: These machines are designed to harvest two rows of potatoes at a time. They dig up the potatoes from the soil, separate the soil, and lift the potatoes onto a conveyor system for sorting and further processing.
• Single-Row Potato Harvesters: These are typically smaller machines used for smaller fields or specialized crops. They work similarly to two-row harvesters but are designed for single-row efficiency.
• Self-Propelled Potato Harvesters: These are large, fully mechanized machines capable of harvesting large fields. They often come with additional features like sorting tables and storage bins.
• Trailed Potato Harvesters: These harvesters are attached to a tractor and are commonly used for medium to large-scale potato operations. They consist of digging units, separation mechanisms, and conveyors to lift and transport potatoes.

INTRODUCTION
Irrigation equipment plays a crucial role in modern agriculture, ensuring that crops receive an adequate supply of water for optimal growth. These systems have evolved over centuries to meet the growing demands of agricultural production, especially in regions where rainfall is inconsistent or insufficient. The construction of irrigation equipment involves various technologies designed to efficiently distribute water to the land, thereby supporting the health and yield of plants. Different types of irrigation equipment are used depending on factors such as the size of the farm, the type of crops being grown, and the availability of water sources. The most common types of irrigation systems include surface irrigation, sprinkler systems, and drip irrigation. Surface irrigation involves the flow of water across the soil’s surface, often through furrows or basins. Sprinkler systems simulate rainfall by spraying water in a controlled manner, while drip irrigation delivers water directly to the roots of plants through a network of tubes and emitters. Each of these systems is designed to optimize water usage, minimize waste, and increase agricultural efficiency. The function of irrigation equipment goes beyond merely supplying water; it is designed to do so in a way that prevents waterlogging, erosion, and evaporation loss. Properly constructed systems ensure uniform water distribution, reducing the chances of crop damage from over-irrigation or drought stress. In addition to providing water, modern irrigation technologies often incorporate automation and sensors, allowing farmers to monitor and adjust water usage based on realtime conditions. This precision farming approach maximizes resource efficiency, contributes to sustainable agriculture, and helps ensure a stable food supply in

THRESHING EQUIPMENT
A thresher is a machine designed to separate grains from harvested crops while minimizing loss and damage. During threshing, various types of grain loss may occur, such as broken, un-threshed, blown, or spilled grains. “Threshing” refers to the process of separating grains from plants. This operation can take place in the field or on the threshing floor, using hand labor, animals, or machines. Regardless of the method used, it’s crucial that threshing is done carefully to avoid grain or husk breakage, which can lower the quality of the product and increase losses from insects or mold. Extra care should be taken when transporting harvested crops to the threshing area to prevent any loss.
Threshing or Shelling Operations
Threshing or shelling operations occur after harvesting and any pre-drying processes. These tasks can be performed either in the field or at the farm, using hand labor, animals, or machines.
The method of threshing or shelling is influenced by various agronomic, economic, and social factors. It can be done in several ways:
• By hand, using simple tools.
• With the help of animals or vehicles.
• Using manually operated mechanical machines.
• Using motorized equipment for mechanical threshing or shelling.
As noted earlier, harvesting and threshing or shelling can often be done together using combine-harvesters or picker-shellers. Regardless of the system used, it’s essential to handle threshing or shelling with care. Improper methods can cause grain or husk breakage, reducing product quality and leading to higher losses from insects and mold. Additionally,

Protected cultivation is an innovative farming approach that involves either naturally ventilated or customized temperature-controlled structures, designed to suit regional weather patterns and the specific needs of cultivated plants. Primarily utilized for vegetables and floriculture, these protected structures create a controlled environment that shields crops from unpredictable climate fluctuations.
This technology grants farmers precise control over crucial factors such as temperature, humidity, light intensity, disease prevention, fertigation, and irrigation, catering to the unique requirements of each crop. Consequently, the practice empowers farmers to enhance profits and achieve a year-round harvest.
GREENHOUSE CONSTRUCTION
Greenhouse construction entails the strategic design and assembly of a structure that offers a controlled environment for optimal plant growth. The framework is typically built using materials such as aluminum, steel, or treated wood, while the covering may consist of polyethylene film, polycarbonate sheets, or glass—each selected for its durability and light-transmitting properties.
Critical aspects of greenhouse construction include selecting an appropriate site, proper orientation for maximum sunlight exposure, establishing a stable foundation, and ensuring efficient framing and cladding. The overall objective is to enhance light penetration, maintain suitable temperature and humidity levels, and ensure adequate ventilation to support healthy and productive crop development.

8.1 Introduction

After deciding the optimum size of farm pond and its dimensions, the next step begins the construction of farm pond. Further the site selection and location of the pond in the selected site to be finished before the construction of pond starts. The selection of site and location of farm pond areas have been discussed in Chapter 3. In this chapter, discussion on methodologies for construction of farm pond including spillways, inlet and outlet structures, design of grassed waterways and embankment have been presented. As a guiding principle, the construction of farm pond involves the following steps:

8.2 Site Clearing

The area where the pond is to be constructed has to be inspected first. The site where pond has to be dug out should be cleared to an extent of about 10 m from all sides of top dimensions of the pond. All bushes, shrubs, stumps and other unwanted materials should be dug out and removed. If there are roots of plants, they should be uprooted. The land may be ploughed and harrowed, if necessary, to get a more or less even topography.

7.1 General

The major portion of water in a crop field gets lost through evaporation and transpiration. Evaporation is the process by which water is changed from the liquid state to vapor state. It takes place from the adjacent soil, water surface or from the surfaces of leaves of the plants. Transpiration is the removal of water vapour through plant body. Evapotranspiration(ET) is the sum of evaporation and transpiration. The process of evaporation and transpiration goes on simultaneously and difficult to separate them in a crop field.

The term consumptive use is used to refer evapotranspiration together with the water used in the metabolic activities of the crop plants. The actual amount of water used in metabolic activities is insignificant (less than 1% to ET). Therefore, the consumptive use and evapotranspiration are often used as synonymous term. It includes the water consumed by the plants

Communication material is the joint product of knowledge, skill and attitude base of the communicator. Further, most of the communication done on behalf of certain organization also reflects the objective, work culture, strategy and contribution of the organization. Hence analysis of communication material is of greater relevance in exploring the trends, vision, behavior and future course of action. In this chapter, we are going to discuss the content analysis; it’s meaning and practical application.

ABSTRACT

The improvement of spatial resolution of satellite remote sensing (RS) imagery, it is possible to update spatial data infrastructure efficiently by satellite RS images. But the RS data volume is vast, so high processing capacity is required. In order to extract the anticipated images from vast image database, effective retrieval technique is vital. The rapid development of Earth Observation System (EOS), the spatial resolution, temporal resolution and spectral resolution of Remote Sensing (RS) image have been improved greatly. Based on contentbased image retrieval, content-based RS image retrieval is put forward and some topics including retrieval pattern, useful image content, feature extraction and similarity measure are researched. After related images are retrieved from vast image database, it is necessary to discover those change areas, so change detection from multitemporal RS images are discussed further. RS image data mining and knowledge discovery is the synergy of Spatial Data Mining (SDM) and Image Data Mining (IDM). It is pointed out that content based RS image retrieval will be potential advantageous in the future and all the techniques discussed in this paper including retrieval modes, content-useful in RS image retrieval. Content-based image retrieval (CBIR) is one of the hot issues in image retrieval, and it can be used to RS image retrieval. That lead to a new area: content-based RS imagery retrieval.

There is no better engineering than life.

What is life - is a perennial question. Life is defined in different ways depending upon who is defining it. Biologists define life using a list of characteristics, such as metabolism, evolution, homeostasis, constant transformation, genetic information, etc. Life has been defined as self-maintaining and self-producing systems. Physicist Erwin Schrödinger (1), argued that living organisms escape the destiny of disordered equilibrium because they are able to take up ‘orderliness’ from their environment. Philosophers have defined life from different angles. They say that life can only be understood fully from an ‘insider’ perspective.

Life is not a random collection of extinct molecules. It is a process of dynamic renewal; everything in life is constantly turning over and renewed. Life exists in diverse forms. Each form is specialised to survive and reproduce in its particular niche.

One understands life from one’s own perspective. For some, life is an ‘objects in flux’ that constantly exchanges matter with the environment. It is systematic material exchange into an organized body. Then there is a view that says that all living organisms deserve moral consideration. All living organisms, however, do not have equal moral significance; vertebrates, for various reasons, deserve more moral consideration than would bacteria or plants. Then there are myriad religious ways to define life. The simplest is “God created the world and all living organisms.” No further questions, accept or reject the hypothesis.

9.1 Introduction

In order to increase the production and productivity of crops, provision of irrigation system is highly essential. A project that makes use of weir or a barrage for providing irrigation to fields is called as direct irrigation system. On the other hand, a storage irrigation system makes use of storage reservoir by construction of dams. In order to provide irrigation by both the schemes, it is necessary to have a network of canal systems. A canal is an artificial channel, generally trapezoidal in shape constructed on the ground to carry water to the fields. The canal systems that provide water to the fields include main canals, branch canals, distributaries, minors and watercourses. It is imperative to design the canal systems properly for a certain realistic value of peak discharge that must pass through them so as to provide sufficient irrigation to the command areas. The flow irrigation that provides irrigation water to the fields may be of two types i.e. Inundation irrigation and Perennial irrigation.

ABSTRACT

The improper disposal of food waste poses an environmental threat. The management of food waste in a sustainable way is always a challenge. Food waste is generated at various stages starting from food production till consumption. The cooked food waste generated due to various reasons leads not only to a loss of the food produced but also the water and energy used to cook it. This cooked food leftover can be served to the needy people or if not possible, can be processed further. This chapter focuses on various technological options for the management of cooked food waste in a sustainable way.

INTRODUCTION
In an internal combustion engine, fuel is combusted within the cylinder to generate power. During the power stroke, the temperature can reach up to 1600 ºC, which exceeds the melting point of engine components. The optimal operating temperature for internal combustion engines ranges between 140 ºF and 200 ºF, making cooling a crucial aspect of engine operation. It is estimated that approximately 40% of the total heat generated is released into the atmosphere through the exhaust, 30% is dissipated through the cooling system, and the remaining 30% is used to produce power.
The cooling system in internal combustion engines plays a vital role in ensuring the engine operates efficiently and reliably. It is responsible for maintaining the engine’s temperature within the optimal range, preventing overheating that can lead to engine damage. The engine generates substantial amounts of heat during combustion, and without proper cooling, these temperatures can rise to levels that exceed the melting point of engine components. This can result in engine failure, reduced performance, and significantly shortened engine life. The primary function of the cooling system is to absorb excess heat from the engine and dissipate it into the atmosphere, keeping the engine temperature within safe limits. This allows the engine to perform at its best while avoiding costly repairs and downtime.
The cooling system works by circulating coolant through the engine block, where it absorbs heat, and then transferring this heat to the radiator, where it is cooled by airflow or a fan. There are various types of cooling systems, including air-cooled and liquid-cooled systems, each offering distinct advantages depending on the engine’s design and application. Liquid cooling systems, which are more
