4.1 Introduction to Function in Python

Python Functions is a block of related statements designed to perform a computational, logical, or evaluative task. The idea is to put some commonly or repeatedly done tasks together and make a function so that instead of writing the same code again and again for different inputs, we can do the function calls to reuse code contained in it over and over again. Functions can be both built-in or user-defined.

Function means sub-program

1. Function definition

2. Function call

Example:

def message: #function definition

print(?hello python”)

message() #function call

Hybrid vigor or heterosis is opposite and complementary to inbreeding depression (reduction in fitness as a direct result of inbreeding). In theory, the heterosis observed after crossing is expected to be equal to the depression upon inbreeding, considering a large number of crosses between lines derived from a single base population. In practice, plant breeders are interested in heterosis expressed by specific crosses between selected parents, or between populations that have no known common recent origin. Furthermore, because heterosis is subject to the interactions between genotype and environment, it is desirable to describe the heterosis of a particular hybrid line for a specific trait at a specific location or under specified environmental conditions.

9.1 Introduction

Many cultures throughout the world see the egg as nature’s perfect meal. Many other kinds of animals lay eggs, yet the vast majority of people eat chicken eggs. There are a number of reasons why the quality of an egg matters today. Grading eggs is so essential. Quality, size, shape, weight, and other characteristics are all taken into account while sorting eggs for grading. To put it simply, food quality refers to the traits of a product that determine whether or not it is accepted by the target audience. Egg quality is based on both industry standards and consumer expectations. Considerations from the outside include egg shell composition, hue, form, and feel. Air cells, egg white, egg yolk, etc., are all examples of internal quality.

Research being a continuous process for a scientific study, previous study provides basis for the research. The review of literature is necessary for developing conceptual frame work and suitable design for the study. It assists the researcher to keep his work going in right direction. The available literature related to the present study has been reviewed under the following heading:

2.1 Differential role accomplished by women dairy farmers from different social strata

Toppo et al. (2004) examined the participation of women farmers in dairy occupation in Anand district of Gujarat and their result revealed that 18.34 percent of the farm women were mostly engaged in activities related to artificial insemination, majority of the respondent (68.34%) participated in cleaning of the shed, while 25.00 percent of the farm women practised manure preparation and 95.00 percent of the respondent were not involved in preparation of gobar gas mixture.

Badole (2006) reported that majority of the responded had low socio-economic status.

Introduction
As global populations increase, so does the demand for high-quality seafood. Aquaculture has emerged as a vital solution, contributing significantly to global fish production and food security. However, traditional practices in fisheries nutrition, primarily reliant on fishmeal and fish oil, face substantial challenges. Overfishing, rising feed costs, and environmental concerns necessitate a shift towards more sustainable and innovative approaches in aquaculture nutrition. This chapter delves into the innovative methodologies and technologies shaping the future of fisheries nutrition, emphasizing sustainability, health, efficiency, and the optimization of nutritional strategies.

Abstract

India is bestowed with immense richness of agro-biodiversity and a rich diversity in landraces / traditional cultivars/farmers varieties in several Agricultural and Horticultural crops. A huge number of crop plants (384) are reported to be cultivated in India. This includes 168 species earlier reported under the Hindustani centre, one of the eight Vavilovian centers of origin and diversity. Further, an enormous richness (326 species) is reported in wild relatives of crop plants. A total of 49 indigenous major and minor crops have been reported in the “History of Agriculture in India”, published by the ICAR. A large number of cereals, millets, oilseeds and vegetable varieties have originated and are cultivated in India, making it one of the richest Centres of Origin of crop and plant diversity in the world.

The liver is an organ that plays a central role in maintaining metabolic homeostasis, in its functions of metabolism, synthesis and storage of nutrients. The cells in the liver are parenchyma cells and non- parenchyma cells. The former include hepatocytes (80% of the cell population) and the later includes endothelial cells, Kupffer cells, lymphocytes and stellate cells. Liver dysfunction or failures are having different etiologies. Liver cancer has the fifth highest cancer incidence in the world, and is the third highest cause of cancer related deaths, with resection of the liver remaining the only curative option.

Following liver injury, the repair process involves two distinct phases: a regenerative phase, in which injured liver cells are replaced with regenerated hepatocytes; and a phase known as fibroplasia or fibrosis, in which connective tissue replace normal parenchyma tissue. The process even though initially beneficial becomes pathogenic when it is not controlled appropriately. Extensive accumulation of extra-cellular matrix (ECM) components ultimately leads to cirrhosis and liver failure. Thus, the ideal strategy to treat liver injury is to generate new hepatocytes replacing damaged cells without causing excessive ECM deposition.

Introduction

Earthworms have been exists on the earth from over 20 million years. Decomposition of organic material that may be plant or animal origin by earthworms is called vermicompost. The earthworm is a natural resource of fertility of soil. Earthworm is lives in the soil. They feed on decaying organic material. After digestion, the undigested material moves through the alimentary canal of the earthworm; and a thin layer of oil is deposited on the castings. This layer corrodes over a period of 2 months. Although, the plant nutrients are immediately available, they are slowly released to last longer period. The digestive process in the alimentary canal of the earthworm can transforms organic wastes to natural fertilizer. Vermicompost is an odorless, clean, organic material containing adequate quantities of N, P, K and several micronutrients essential for plant growth. Vermicompost is an ideal nutrient source for organic farming. It is eco-friendly, non-toxic, consumes low energy input for composting and is a recycled biological product. Vermicomposting has gained popularity in both industrial and domestic scenery because as compared with conventional composting, it provides a way to treat organic wastes more quickly. It generates a product which has a lower salinity levels, and therefore more beneficial to plant mediums. Vermicompost is nutrient rich organic fertilizers which also contain water soluble nutrients and soil conditioner in a form that is relatively easy to absorb for plants. Worm castings are nothing but organic fertilizers because the earthworms grind and uniformly mix minerals in simple forms. Plants need least efforts to obtain these nutrients from vermicompost. The worm digestive system creates environment that allow certain species of microbes to flourish to help for creating the “living soil environments for plants”.

The chemical changes in organic wastes undergo include deodorizing and neutralizing. The pH of the casting is 7 (neutral) and the casting is odorless. The worm casting contains bacteria, so microbial activity is promoted. Excellent quality of compost can be produced in ambient temperature condition in a short period of time by using proper species of earthworm. The earthworms promote faster decomposition of organic material as compared to compost pits without earthworms.

Climate Change - An overview The most studied topic in recent years was climate change, due to its increasing importance. Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle or due to anthropogenic activities, since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas. The process of raising the earth’s temperature is known as global warming. Climate change is one result of global warming in different places on the planet. Many people think that climate change means only global warming or an increase in temperatures. But the rise in the temperature is only the beginning of the story. Because in the Earth system everything is connected to one another, changes in one area or in one aspect of the system can influence changes in other areas. The consequences of climate change include flooding, intense droughts, water scarcity, wildfires, rising sea levels, melting polar ice, catastrophic storms and declining biodiversity. Adapting to climate change consequences protects people, businesses, livelihoods, infrastructure and natural ecosystems. It covers current impacts and those likely in the future.

Introduction

Potato (Solanum tuberosum L) is one of the major starchy tuber vegetable crops of the world. It is a unique crop which can supplement the food needs of the country in a substantial manner. Today, potato is the need of life or poor man’s food in many countries including India. Potato production in India has made tremendous progress only with the development of new technologies in different fields of agriculture. It has been observed that the farmers are not adopting recommended practices and consequently not realizing the potential yield of potato. To understand the problems of farmers in the adoption of complete recommended farm practices, researchers as well as extension workers should come out with some concrete findings and suggestions, which can solve these problems. It has been seen that a large number of techniques and practices do not reach the farmer’s fields and those carried to the farmers get considerably distorted or often adopted partially with the result that farmers do not get the potential yield.

10.1 Introduction

The primary purpose of egg packaging is to keep the egg safe from damage, such as cracking, while in transit. By limiting gas exchange via the shell and shell membrane, the egg package may help safeguard the egg’s internal quality. Once an egg has been deposited, it is immediately exposed to the conditions of the henhouse. In this environment, it is exposed to many different microorganisms. Almost often, there are no negative effects on health. However, there are microbes that can ruin eggs and others that can cause food poisoning. Salmonella bacteria are found in the digestive tract of all animals and can contaminate the poultry houses.

Introduction

Resources are used unscientifically commonly. For example applying feed somewhere in the pond results in loss, but by using technology, we can know when to apply where to apply, and how to apply which leads to efficient management of resources. Monitoring should be continuous which is not possible and very difficult for humans, but with technology, it could be monitored and the status could be known even from home which is communicated through mobile, which is sent by sensors installed. The data are also easily maintained. When technology is used, resources are efficiently utilized, since everything has a demand and that can be satisfied. So resources can easily be maintained which reduces wastage. Field management is a very skilled activity and it needs years of experience and onsite exposure which needs skilled labour, in such cases technologies aids with better methodologies. When the resources are applied at the right time, at the right amount, the growth becomes normal which increases the produce quality. After a product is produced, it has to be sent to a series of channels such as transport, market etc. and a technology should backup and monitor everything. The produce after being produced should be sold and many apps can be downloaded to improve the marketing. The whole world is changing within a period of time. So one should stay updated to impress the livelihood and the wide knowledge on technology helps to lead a better life with easy management practices. Thus data driven technology interventions are needed for efficient management of resources, monitoring of things anytime & anywhere, reduction of wastage of resources, reduction of dependence on trained and skilled manpower, enhanced product quality, better integration, better marketability, to stay updated with latest knowledge and access to other knowledge source for better upgrades.

The chapter further covers major insect pests and diseases, harvesting, postharvest handling and yield, highlighting the importance of Champak as both a traditional flower crop and a valuable raw material for perfumery.

Abstract

Cultivation of cash crops of good quality potent to give good economic returns depends largely upon adoption of modern practices in agriculture. The region under test consideration is completely irrigated and cultivates mostly the crops of grapes and sugarcane. A field testing that was carried out for the pumps used by local farmers, revealed glaring inefficiency in pump operation. This is attributed to numerous reasons, the standout of them-being improper pump selection and deviation from operating point. Survey of the farming pattern helped to establish nexus between the energy usages per acre for the two crops. Carbon Footprint was determined for the electricity utilized in these farms. Adoption of selection methodologies and efficient practices would lead to considerable saving in electrical power consumption. The impact of adoption of efficient practices was therefore quantified.

Hybrid technology is one of the options to boost crop productivity. Hybrids give more yield than improved varieties under optimum crop production conditions. Further, uniform size, earliness, better adaptability to adverse environments, better transportability due to better keeping quality and resistance to stresses are certain additional advantages of growing hybrids with better monetary return to the growers. Hence in coming years, hybrid technology has to go a long way in our country to meet the future challenges (Kalloo et al., 2000). Thus, it is pertinent to have an overview of the methods of the hybrid seed production technology. Various methods are as follows:

ABSTRACT

Genetic relationships were estimated among twenty five ashgourd (Benincasa hispida (Thunb.) Cogn.) landraces of different types using PCR-based random amplified polymorphic DNA (RAPD) markers. The molecular survey of the ashgourd germplasm by RAPD using three random primers resulted in twenty scorable bands (average of 6.66 bands per primer) of which two were monomorphic and rest, 18 were polymorphic (90.0%). Pair-wise genetic similarities among the landraces determined using Jaccard’s coefficient ranged from 0.14 to 1.00. The dendrogram based on clustering matrix separated the landraces with morphologically distinct smooth textured fruits from waxy textured fruits and the former group showed less divergence than the latter. With in the group of waxy textured fruits, limited variation was detected among landraces with small and medium sized fruits. Further, morphologically similar landraces with large fruits form distinct clusters with in the major clusters. The study demonstrated the usefulness of the RAPD marker analysis in effectively assessing the genetic relationship present among the ashgourd landraces examined.

Introduction
Fish raised in cold water fisheries are species that flourish in temperatures usually below 20°C. To increase fish production and provide jobs for the local population, cold water fisheries have been established throughout India. One important region in India where cold-water fisheries have been effectively Exclusively Distributed by NIPA GENX Electronic Resources and Solution Pvt. Ltd. New Delhi established is Himachal Pradesh. There are plenty of cold-water rivers and streams in this area that are perfect for fish farming. To encourage cold water fisheries, the state government has launched several programmes, including financing for the construction of fish farms and the purchase of supplies and equipment. The most often farmed fish species in Himachal Pradesh's cold water fisheries are brown trout, rainbow trout, and mahseer (Bhat et al., 2023). India is well known for its cold-water fish, which are highly prized for their flavour. In addition to Himachal Pradesh, other states that have embraced cold-water fisheries include Jammu and Kashmir, Uttarakhand, Sikkim, and Arunachal Pradesh. However, obstacles to their growth include restricted market access, a lack of technological know-how, and inadequate infrastructure. The many cold-water fisheries in northern and northeastern India demonstrate the region's enormous potential despite these obstacles (Pandey et al., 2021).
These fisheries support a variety of fish species that have evolved to live in colder waters. With an approximate length of 2,500 km, the Himalayas stretch from Nanga Parbat (8,126 m) in the west to Namcha Barwa (7,756 m) in the east, encompassing an area of 594,400 km². Its western boundary is the high plateau of Tibet; its northern boundary is the Karakoram Mountains; the range's southern and northern limits are separated by 200–400 km. The Siwaliks, the lesser and Greater Himalayas, and the Trans-Himalaya run parallel to each other from south to north and are identified by their physiographic features and geological histories. With a combined catchment area of around 160,000 km², the Indus and Brahmaputra are the longest of the nineteen major rivers that meander through the Himalayas. When these rivers emerge from the mountains; many of them pass through wide valleys. According to Shinn et al. (2015), the distribution of fish species in Himalayan streams is influenced by variables such as flow velocity, substratum type, water temperature, and the availability of food. The intensification of aquaculture systems has resulted in the appearance of new pathogens and a greater dependence on antibiotics and other supplements, which threaten the health of fish, humans, and the environment (Watts et al., 2017). Aquaculture faces a great deal of difficulty due to diseases, which result in large production losses that surpass six billion USD annually (Bhat et al., 2023). According to estimates, 10–50% of aquaculture production expenses are related to disease management (Sahoo et al., 2017). This book chapter provides a brief overview of some prevalent parasite, viral, and bacterial diseases that have been linked to temperate and cold-water aquaculture, along with information on potential remedies and preventative measures. Commonly disease found in fish are presented in (Table 1, 2 and 3).

Abstract

This paper is intended to focus on importance of Agro-diversity, seed conservation practices, impact of monoculture on biodiversity and connected formal and informal institutions and governance mechanisms. Furthermore this paper explores to discuss the innovation processes, technologies which help in conserving existing diversity, process of evolving newer lines that eventually meet the needs of the farems. Open Source Seed Network (OSSN) would be an organisational platform which consists people engaged in conservation, farmers that can develop Value for Cultivation and Use data for the existing crop varieties in different agro- climatic growing conditions using participatory varietal selection. Farmer breeders engaged in selection and development of newer varieties and Farmers institutions involved in production and marketing of seed to other farmers. Further to elaborate the process the stakeholders will perform the responsibility of conservation and revival of the existing varieties, PVS for generating VCU data, PPB, perform Maintenance Breeding, maintain community seed banks, seed production and marketing. In addition we attempts to focus on mechanisms while making public sector as partners in participatory plant breeding which enable development of locally suitable varieties. An access and benefit sharing mechanism based on an open source model rather than on exclusive rights based is planned for free exchange of germplam within the purview of General Public License for plant Germplasm (GPLGP). This paper emphasise advantages of GPL that prevents exclusive rights, bio piracy, safeguarding farmer derived genetic resources, develop legal/institutional framework that eventually allows farmers to freely exchange, save, improve and sell seeds. In the end this could trigger the emergence of an institutional framework in which farmers and plant scientists work together in plant improvement that contribute to a sustainable food system.
