Introduction

Understanding the variation in grain protein content is the pre-requisite of its improvement in modern rice varieties. The measure of quantitative and qualitative aspects of grain storage protein content includes estimation of soluble and total grain protein, quantifying various fractions, viz. glutelins, prolamins, globulins and albumins and their profiling through SDS-Page and  estimation of amino acid. As traditional chemical methods for protein content determination are destructive in nature. All these estimates comprehensively give insight into the diversity of storage protein in rice germplasm. The standard procedures followed for all these estimates are briefly stated in the  following sections.

Estimation of Total Grain Protein Content in Rice

The total protein is estimated via estimation of total N through the Kjeldahl method whereas soluble protein is estimated through Lowry method, Dumas method and Bradford method. But for estimation of large number of genotypes all these processes are tedious, time-consuming, and costly. Near-infrared spectroscopy (NIRS), as a non-destructive detection technique, can achieve rapid quantitative determination of protein contents and become an important development direction to replace traditional chemical detection methods.

INTRODUCTION TO FLIGHT PLANNING FOR AGRICULTURAL DRONE
Flight planning for agricultural drone operations entails selecting the appropriate drone, preparing the drone and its equipment, and devising a flight trajectory. Drone flight planning software enhances safety and ensures compliance.
Why is Drone Flight Planning Important?
Effective drone flight planning establishes the groundwork for effective mapping and surveying operations. It entails formulating a comprehensive flight plan for the drone, guaranteeing that data acquisition is precise, effective, and secure. Inadequate preparation exposes operators to the risks of missing data, overlapping imagery, or delays in mission execution. Principal advantages comprise:
• Precise Data Acquisition: Strategically organized flights provide uniform overlap among photos, essential for producing high-quality orthomosaics and 3D mappings with a drone.
• Optimized Resource Utilization: Efficient flying trajectories reduce energy consumption and time allocated for data acquisition.
• Improved Safety: Pre-arranged missions circumvent impediments and comply with airspace laws, thereby mitigating dangers. COMPONENTS OF DRONE FLIGHT PLANNING Defining the Mission Objective Each mapping or surveying endeavor commences with a clear comprehension of the precise purpose. The mission aim dictates the necessary data and the appropriate tools for land surveys, construction site inspections, or agricultural mapping.

Gadget: A slang word applied to any small, handy appliances or devices.

Gagging tape: A metal measuring tape used to determine the depth of liquid in a tank.

Gal.: The unit of acceleration in the centimeter-gram-second system, equal to 1 centimeter per second square; commonly used in geodetic measurement. Formerly known as Galileo, symbolized as Gal.

Galling: A characteristic of metals, which causes them to seize when, brought into intimate contact with each other. A material, which is subjected to galling, is one, which will seize or ‘freeze’ when brought into close contact with like material under pressure and no lubricant.

Gallows plough: An animal-drawn plough, the end of the beam rests freely on a bolster fixed to two front wheels, which is drawn through the front wheel assembly.

Galvanic corrosion: The accelerated corrosion of one metal when it is connected with a more noble metal, e.g. if steel and copper are connected together in seawater, the steel will suffer accelerated corrosion and the copper will be protected.

Introduction

Jackfruit (Artocarpus heterophyllus) is the largest edible fruit in the world. It is a seasonal fruit found in almost all the humid tropical regions of the world. It is very popular all over India and is believed to be of Indian origin. Flesh of jackfruit is starchy and fibrous and is a source of dietary fiber. Varieties are distinguished according to characteristics of the fruit’s flesh. In Kerala, two varieties of jackfruit predominate: varikka and koozha. Varikka has a slightly hard inner flesh when ripe, while the inner flesh of ripe koozha fruit is very soft and almost dissolving. Strong aroma of the fruit accounts popularity of its processed products. Each year, approximately 30-50% of the total harvested fruit is spoiled because of lack of post-harvest processing in India

Jackfruit has more protein, calcium, thiamine, riboflavin and carotene than banana. Edible bulbs of ripe jackfruit are consumed for their fine taste and pleasant aroma. The fibre content helps to protect the colon mucous membrane by decreasing exposure time as well as binding to cancer-causing chemicals in the colon. Fresh fruit has small amounts of carotenoid and flavonoid pigments such as ß carotene, xanthin, lutein and cryptoxanthin-ß. Together, these compounds play vital roles in antioxidant and vision functions.

Half round file: A file, which is flat on one side and curved on the other. The amount of convexity never equals a semicircle.

Half section: In mechanical drawing, a sectional view that terminates at the centreline, showing an external view on one side of the centerline and on the other side an interior view.

Hammer: An instrument or tool used for striking blows in metalworking, driving nails, etc. Hammers are of various kinds, each bearing a name according to the purpose it has to serve.

Hammer mill: 1. A type of impact mill or crusher in which materials are reduced in size by hammers revolving rapidly in a vertical plane within a steel casing. Also known as beater mill. 2. A grinding machine, which pulverizes feed and other products by several rows of thin, hammers revolving at high speed.

India is the largest producer and consumer of pulses in the world, accounting for 33 per cent area and 25 percent production. Pulses are mostly grown under rainfed conditions in marginal to sub-marginal lands. Once a net exporter it is presently one of the largest importer of pulses as our demand outstrips domestic production. While the traditional cropping pattern almost always included a pulse crop either as a mixed crop or in rotation, the commercialization of agriculture has encouraged the practice of sole-cropping. As a result, the annual import has increased from 0.50 million tonnes to 1.80 million tonnes during the last five years and contribution of pulses in the national food basket reduced from 17% to 7%. Pulses are generally grown on marginal and sub-marginal lands under rainfed conditions with low inputs and suffer heavily due to biotic and abiotic stresses, resulting into low productivity. Challenges for pulses in India are decline in area of pulses, low genetic yield potential, low realized yield, instability in production, climate change, biotic and abiotic stresses, poor seed replacement rate, post harvest losses, wide fluctuation in price, no regular MSP/procurement policy, poor availability of critical inputs in productivity zone and poor transfer of technology.

7.1 INTRODUCTION

Gardening is a practice of growing different kinds of horticultural crops in a particular land area as a part of horticulture either for consumption or sale, export, beautification etc. Basing on the crops grown, gardens are named accordingly, e.g., for raising vegetables, it is vegetable gardens; for fruit crops, it is orchard; for plantation crops, it is estate plantation; for ornamental plants, it is gardening and landscape etc. The history of gardening is not new. In ancient time kings, emperors, rulers, sages were establishing different types of gardens for different purposes.

Unsupervised classification is the technique of classification of raster data in which no prior information is provided by the user. Raster data is classified based on their spectral characteristics such that the pixels having similar spectral properties in the multispectral feature space are grouped together in one class. Unsupervised classification is mainly performed by clustering algorithms. The purpose of these algorithms is to minimize within cluster variability and maximize between clusters variability. The user must interpret and label the classes after performing unsupervised classification. This method of classification requires minimum data which makes it easy and quick, but user has toput efforts in identification of the classes. This method could be useful when user doesn’t have any prior knowledge about the study area. This method removes subjectivity and enables us to get the unique classes which might be unrecognized by the user. K-means is the most commonly used method for performing unsupervised classification. In this chapter, we have discussed K- means, CLARA and unsupervised random forest method for classification of raster data in R.

The term probiotic means “for life” and it is currently used to refer bacteria that are associated with beneficial effects for humans and animals. The credit for first observation made on the positive role of some selected bacteria was attributed to Eli Metchnikoff, the Russian born Nobel Prize recipient, worked at the Pasteur Institute in the beginning of the last century. Metchnikoff suggested that - “the dependence of the intestinal microbes on the food makes it possible to adopt measures to modify the microflora in our bodies and to replace the harmful microbes by useful microbes”. Interim Henry Tissier, a French paediatrician, observed that children with diarrhea in their stools had a low number of bacteria which are characterized by a peculiar Y shaped morphology. On the contrary, these “bifid” bacteria were abundant in healthy children. Based on these observations, Tissier suggested that “bifid” bacteria could be administered to patients with diarrhoea to help restore a healthy gut microflora. These two scientists were the first to give scientific intimation for the use of probiotics when even the term probiotics was not coined. Later in 1965, the term probiotics is coined by Lilly and Stillwell to describe substances produced by one microorganism, that stimulate the growth of another. Subsequently, Parker defined probiotics as organisms and substances that contribute to intestinal balance. Further, Fuller (1989) improved the Parker’s definition of probiotics as “live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance”. Havenaar and Huis in’t Veld (1992) extended the probiotic definition with the description: “A viable mono or mixed culture of microorganisms which, applied to animal or man, beneficially affects the host by improving the properties of the indigenous microflora”. At the end of the millennium, Salminen and his coworkers (1999) proposed the following definition: “probiotics are microbial cell preparations or components of microbial cells that have a beneficial effect on the health & well- being of host”. Whereas FAO/WHO (2001) defined probiotics as “living bacteria that, when administered in adequate amounts, confer a health benefit on the host”. This definition for probiotics is widely accepted.

Basic concepts of plant stress, acclimation and adaptation
Energy is the absolute requirement for the maintenance of structural organization over the lifetime of the organism. Maintenance of such complex structural organization over time requires a constant flow of energy through all biological organisms, which provides the dynamic driving force for the performance of important maintenance processes (the processes which are essential for an organism to remain alive and continue as the species) such as respiration, assimilation, nutrition, cellular biosyntheses and transport to maintain its characteristic structure and organization as well as the capacity to replicate and grow. Maintenance of such steady-state results in a meta-stable condition called homeostasis. Thus, “Homeostasis” is defined as a selfregulating process by which a living organism can maintain internal stability while adjusting to changing external conditions. It is the state of balance among all the living systems needed for the organism to survive and function properly.
Plant stress
Any change in the surrounding environment may disrupt homeostasis. Environmental modulation of homeostasis may be defined as biological stress. Thus, plant stress implies some adverse effect on the physiology of a plant induced upon a sudden transition from some optimal environmental condition where homeostasis is maintained to some suboptimal condition which disrupts this initial homeostatic state.

Introduction

Hydrological data visualization plays a crucial role in analyzing and understanding the behavior and characteristics of water resources. By visualizing hydrological data, we can gain insight into the distribution, variability, and trends of different hydrological variables such as river flow, precipitation, groundwater levels, and water quality parameters. This information can help decision-making in areas such as water resources management, flood forecasting, and climate adaptation.

R Language is a popular and versatile tool for hydrological data visualization, offering several powerful packages for data analysis and visualization. Each of these packages has its own strengths and limitations, which can be leveraged depending on the specific needs of a given analysis. For example, ggplot2 is an extensively used package for creating publication-quality static plots that are customizable and visually appealing. This package is based on the grammar of graphics, which provides a new plotting system that combines the benefits of both base and lattice graphics. ggplot2 can be used to create a wide range of plot types, including time-series plots, spatial maps, and scatterplots. It provides several options for customizing plot elements such as axis labels, legends, and plot themes. On the other hand plotly offers interactive and dynamic plots that can be easily shared and embedded in web applications. With plotly, we can create plots that allow for zooming, panning, and hovering over data points to display additional information. This package is mainly useful for exploring relationships between hydrological variables. In addition to these packages, hydroTSM provides functions for reading, manipulating, and plotting time-series data. hydroTSM can help us create time-series plots of variables such as river f low, precipitation, and temperature, with options for adding trend lines error bars, and annotations.

Definition

• If a communication source decodes the message that he encodes, if the message is put back to his system, we have a feedback - Berlo (1960)

• Feedback is defined as the action reaction interdependence in communication.

• The return to the input of a part of the output is the feedback.

• Feedback is the reaction on the part of the receiver to a sender's communication.

Feedback or response of the audience is the ultimate objective of any communication process or function. Response of an audience to message received may be in the form of some kind of physical or mental action. Until the desired action results, extension communication does not achieve its most essential objectives. The response of the audience (whether in the form of action or reaction) can be used by a communicator as a check of his own effectiveness and a guide to his own future action. When a source receives feedback, that is rewarding, he continues to produce the same kind of message. When he gets non-rewarding feedback, he eventually will change his message. Schramn (1955) points out that each person in the communication process is both an encoder and decoder. He receive and transmits. However, a person will decode a message and interpret it in accordance with his own experience.• Feedback means carrying out significant responses of the audience back to the communicator.

HOUSING OF LABORATORY ANIMALS

Objectives

The important criteria to be kept in mind for the construction of animal house are:

• Got to satisfy the requirements of animal care takers and animal technician whose place of work it is.
• Got to satisfy animals which are house in animal house.
• Research workers who conduct research on animal in the laboratory should be satisfied.

Materials required- Small animal house, Animal colonies, type of cages and equipments.

Growing population has increased the demand on food supply. Providing safe and hygienic food to the population is an essential consideration. Food safety systems and tools need to be in place to assure safe food, until which the food businesses would not flourish or be able to build their reputation. Food safety systems and management tools are important as they assist food business organizations to build confidence in people regarding food safety.

Introduction

Problem soils are those that impede agricultural productivity owing to mineral stress, dryness, acidity, sodicity, waterlogging, etc. Vertisol, acid sulphate soils, saline-sodic soils, peat soil, and fine textured alluvial soils were the categories Beek et al., (1980) used to group the problematic soils. In addition to vast areas where deficiencies of zinc, phosphate, and iron, or excesses of iron, aluminium, and manganese limit rice yields, Ikehashi and Ponnamperuma (1978) observed that approximately 100 million hectares of land that are physiographical and climatically suitable for rice lie idle due to the soil toxicities caused by salt, alkali, acid, or organic matter. Problem soils can be broadly defined as those that have unfavourable conditions whether natural or artificially created that severely restrict the successful development of crops. Soil profiles with high groundwater levels and a less permeable argillic layer, degraded soils, sandy soils with low fertility, coastal soils that frequently flood, and laterites could all be categorised as problem soils. Without taking into account related soil functions, soil health is evaluated independently. It is also based on the f indings from a few soil tests for different criteria. 2015 has been recognized the International Year of Soils by the 68th UN General Assembly in recognition of the importance of soil health in all dimensions.

Concept of Ideotype breeding
In the breeding programme, elite crop varieties are developed through combination of relatively low-frequency alleles which are of known agronomic / horticultural importance (Lyu et al., 2013). During breeding programme, these elite varieties are developed targeting different main objectives, such as yield, product quality, resistance to abiotic and biotic stresses and agronomic suitability.
A crop ideotype is defined as an idealised structural model, combining both morphological and physiological traits, with the potential to maximise yield and quality within a defined environment (Donald, 1968). Ideotype generally include factors that increase the survivability of the plant such as drought resistance, resource use efficiency, root architecture and disease resistance (Arraiano et al., 2006; Rezzouk et al., 2022). Definition of “Ideotype” may be broadened through combination of morphological and physiological traits (or their genetic bases) conferring to satisfying adaptation of a crop to a particular biophysical environment, crop management and end use.

The Convention on Biotechnology has defined biotechnology as “any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or process for specific use”. The global food requirement is increasing with growing population, so the productivity gap could be filled by improving genetic health. Animal breeding focuses on genetic improvement through biotechnological and genomic approaches. Genetic progress is influenced by the type of biotechnology such as selection accuracy, genetic interval, intensity of selection, genetic variance. It helps to improve animal production, treatment of genetic disorders, production of transgenic animals resistant to diseases, vaccine production and also to maintain genetic diversity for endangered species. Genomic selection is a type of marker assisted selection. It improves the genetic gain by decreasing genetic interval and improving reliability. These novel approaches have high potential in animal breeding, if executed judiciously may provide practical benefits to mankind. The magnitude of genetic improvement of livestock species

TQM is an integrative philosophy of management for continuously improving the quality of products and processes. It is used around the world.

TQM functions on the premise that the quality of products and processes is the responsibility of everyone who is involved with the creation or consumption of the products or services offered by an organization. In other words, TQM capitalizes on the involvement of management, workforce, suppliers, and even customers, in order to meet or exceed customer expectations. Considering the practices of TQM as discussed in six empirical studies, Cua, McKone, and Schroeder (2001) identified the nine common TQM practices as cross-functional product design, process management, supplier quality management, customer involvement, information and feedback, committed leadership, strategic planning, cross-functional training, and employee involvement.

TQM and Six Sigma

The Six Sigma management strategy originated in 1986 from Motorola’s drive towards reducing defects by minimizing variation in processes. The main difference between TQM and Six Sigma is the approach Six Sigma is a business management strategy originally developed by Motorola, USA in 1986. As of 2010, it is widely used in many sectors of industry, although its use is not without controversy.

Introduction

In India the economy is based on rural and agrarian and decline with land holding area poses a serious challenge to the sustainability and profitability of farming. In view of the decline in per capita availability of land from 0.5 ha in 1950-51 to 0.15 ha by the turn of the century and a projected further decline to less than 0.1 ha by 2020, it is imperative to develop strategies and innovate new agricultural technologies that enable adequate employment and income generation, especially for small and marginal farmers who constitute more than 80% of the farming community. The crop and cropping system based perspective of research needs to make way for farming systems based research conducted in a holistic manner for the sound management of available resources by small farmers (Jha, 2003). Under the gradual shrinking of land holdings, it is necessary to integrate land based enterprises like fishery, poultry, duckery, apiary, field and horticultural crops, etc. within the bio-physical and socio-economic environment of the farmers to make farming more profitable and dependable (Behera et al., 2004). No single farm enterprise is likely to be able to sustain the small and marginal farmers without resorting to integrated farming systems (IFS) for the generation of adequate income and gainful employment year-round (Mahapatra, 1992; 1994). Farming systems approach, therefore, is a valuable approach to address the problems of sustainable economic growth for the farming communities in India.

Communication is the fundamental process of conveying information between two or more individuals or within a group. Communication process involves distinct components: a sender, a recipient, a message, and a medium through which the message is transmitted. Importantly, the exchange of a message frequently carries emotional and cultural connotations. Variations in perception and interpretation among recipients may result in disparities between the intended message of the sender and its actual understanding by the receiver, thereby underscoring the nuanced nature of communication dynamics

Intra-personal Communication

Intra-personal communication involves an individual engaging in self-talk or internal dialogue. This process is an unconscious act inherent to all human beings, wherein individuals contemplate various plans and problems of daily life within their minds. People often discuss matters internally before sharing them with others or documenting them. Intra-personal communication is so ingrained in our everyday lives that it often goes unnoticed, yet it is the fundamental form of communication. All communication originates in the human mind before being expressed in interpersonal, group, or mass communication.

Inter-personal Communication

Inter-personal communication occurs between two individuals, involving one person talking, discussing, or arguing with another. This one-to-one interaction can take many forms, such as casual conversations between friends, information exchange, persuasion, problem-solving, counseling, or simple chatting. This method is widely used in extension work, particularly with poor farmers who are often illiterate and have limited access to other modes of communication. Despite being time-consuming, inter-personal communication allows for meaningful interaction between farmers and extension workers, facilitating mutual understanding and ensuring the accurate transmission of information through feedback.
