A laboratory is essential for research work in science and development. Most of the research institutes have dedicated laboratories for researchers and students to conduct experiments, perform research work, as well as to provide hands-on learning/training to students. There are certain rules and regulations laid down by the laboratory in-charge which need to be followed strictly for safety purposes. Some of the laboratories keep ‘safety manual’ for researchers to read before entering into the laboratory to conduct experiments. Whenever safety is compromised in a laboratory, there is increase in risk of unwanted incidents in the laboratory. Storing food/beverages in the same refrigerator where laboratory chemicals are kept may lead to disastrous effects on health. This chapter aims to provide instructions in brief on the things to be performed (Do’s) before and after entering onto a laboratory as well as the things never to be done (Don’ts) in a laboratory for the safety reasons.

Good Laboratory Practices (Do’s)

• P Wear apron/labcoat while working in the laboratory.
• P Use gloves/respiratory mask/fumehood while handling toxic/volatile/inflammable chemicals/reagents.
• P Use pippet or pippetor for safety in transfer of solutions.
• P Protect eyes, face and naked parts of the body from UV radiations. Use safety goggles or face mask/apron.
• P Keep your eyes away from Liquid Nitrogen and use cryogloves while handling it.
• P Arrange all the necessary materials/solutions before starting the experiment.
• P Periodically fumigate/ozonize culture and inoculation rooms.
• P Autoclave all contaminated materials before discarding.
• P Pre-treat gel or solution containing Ethidium Bromide (EtBr) before discarding into laboratory waste-disposal bin, and use gloves while handling them.
• P Burn all the transgenic plant materials in an incinerator after taking necessary observations.
• P Make entry in the designated log-book and clean the instrument after using it properly.
• P Switch-off the instrument after use or when not in use.
• P Wash hands with soap and remove the labcoat before leaving/going out of the laboratory7.
• P Ensure that switches for fans/lights, and water taps are off while leaving the laboratory.
• P Follow the biosafety guidelines suggested for handling and disposal of the hazardous chemical.

Raichak, Kamar Pool, and Diamond Harbour Road were the working locations. Groups formed by identifying the interested women from the selected location. In each group, there are 25 women registered for the training. The selected members were introduced to the ornamental fish farms located at Amtala to appraise the working possibilities and viability of the activities.

Abstract
Agriculture is still main grindstone for the population in India. Even though the insistence for the agriculture produces expanding constantly due to the rising in the population, Due to this, Indian farmers are not getting assisted in this context. The rate of drop out from agriculture is enhancing from generation to generation. One of the main apprehensions is agriculture which is not becoming effective for the farmers. Thus to preserve their lives many farmers are quitting agriculture and migrating to urban areas ultimately. This will leads to deterioration in supply of food grains to integrated nation. At the same time, the capacity of land is declining due to reduction in the fertility of the land over years. The input cost for agriculture is also increasing steadily. The situation arrived where we have to enhance the income levels of the farmers along with attaining the sustainability in the agricultural practices. Therefore, a shift from agriculture to agribusiness is an important pathway to revitalize Indian agriculture and to make more attractive and profitable venture.

Abstract
 
The field experiment was conducted during rabi season at the Baruipur Research Farm of the Calcutta University using treatments as T1-NPK 100%, T2- Compost 100%, T3- Compost 50%+NPK 50%, T4-Vermicompost. 100%, T5- Vermicompost 50%+NPK 50%, T6-FYM 100%, T7-FYM 50%+NPK 50%, in a Randomised Block Design (RBD) replicated thrice.  The results show that the amount of available N content in soil  has been found to be increased with the progress of crop growth upto 45 days of crop growth and thereafter, the amount of the same decreased with the crop growth irrespective of treatments. The amount of P content in soil has been found to be increased with different treatments, being maintained highest amount (18.30 kg/ha) in the treatment Vermicompost 50%+ NPK50% followed by the treatment where 100% NPK and 100 % vermicompost were applied. The results show that the amount of K content in soil was increased initially and thereafter, the amount of the same decreased with the progress of crop growth.

Presently the farming situation urges need to develop farming techniques, which are sustainable from environmental, production, and socio-economic points of view. Modern agricultural production throughout the world does not appear to be sustainable in the long run. Sustainable agricultural development “is the management and conservation of the natural resource base and the orientation of technological and institutional change in such a manner to assure the attainment and continued satisfaction of human needs for the present and future generations”. Such sustainable development in the agriculture, forestry and fishery sectors, conserves land, water, plant and animal genetic resources, is environmentally non-degrading, technically appropriate, economically viable and socially acceptable. Such concerns imparted a way to organic farming. It is the need of the day to understand the prospects and problems of organic farming to launch a successful and flawless organic production programme in the farm of environment.

Organic farming

It is the most widely recognized alternative farming system to chemical agriculture evolved during 1940’s largely in response to the publication of J.I Rodale in the U.S., Lady Eve Balfour in England and Sir Albert Howard in India. In 1980, USDA released a landmark report on organic farming. The report defined organic farming as follows;

“Organic farming is a production system, which avoids or largely excludes the use of synthetically compounded fertilizers, pesticides, growth regulators, and livestock feed additives. To the maximum extent feasible, organic farming systems rely upon crop rotations, crop residues, animal manures, legumes, green manures, off-farm organic wastes, mechanical cultivation, mineral bearing rocks, and aspects of biological pest control to maintain soil productivity and tilth to supply plant nutrients, and to control insects, weeds, and other pests”.

Water is a critical and essential nutrient in poultry production, necessary in greater amounts than any other nutrient. It plays a vital role in various physiological processes such as digestion, metabolism, nutrient transportation, enzymatic and chemical reactions, regulating body temperature, and lubricating joints and organs. Water deprivation can have severe consequences on poultry health, impacting growth, egg production, and even leading to increased mortality if prolonged. Therefore, providing cool, clean water that is free from contaminants is crucial for maintaining poultry health and optimizing farm profitability.

Water Consumption in Poultry

Water consumption in poultry varies under different conditions. Generally, under thermo-neutral conditions, birds will consume approximately twice the amount of water as the amount of feed. However, water intake is influenced by several factors, including environmental temperature, relative humidity, dietary salt and protein levels, the productivity of the birds (growth rate or egg production), and the bird’s ability to reabsorb water in the kidneys. In poultry houses, water consumption tends to be higher in areas with more birds and higher ambient temperatures. Studies indicate that birds prefer water at about 10°C; when water temperatures exceed 27°C, both water intake and daily weight gain are significantly reduced.

Abstract
Sustainable entrepreneurship integrates social and environmental goals with economic viability, aiming to enhance human well-being while preserving ecological systems for future generations. Unlike conventional entrepreneurship, which prioritizes profit, sustainable entrepreneurship focuses on maintaining resources and bolstering socio-ecological systems through innovative, risk-taking ventures. It combines elements of ecopreneurship, social entrepreneurship, and institutional entrepreneurship to address environmental degradation and social inequities, creating value for diverse stakeholders. By realizing sustainability innovations, such enterprises meet unmet demands for environmental and social  improvements, contributing to equitable resource distribution and long-term societal benefits. The growing emphasis on sustainable development as a public policy priority underscores the need for entrepreneurship that supports ecological and social processes, fostering inclusive growth and resilience.

Commercial farming is an increasingly vital component of agricultural development strategies in many states. State governments often implement various livelihood models aimed at promoting commercial farming to enhance agricultural productivity, boost local economies, and improve farmers’ livelihoods. Here are some common commercial farming-based livelihood models that state governments may employ:
1. Cooperative Farming
• Description: Farmers form cooperatives to pool resources, share equipment, and access larger markets. This model strengthens bargaining power and reduces costs.
• Government Role: States may provide technical assistance, financial support, and facilitate access to markets.
2. Contract Farming
• Description: Farmers enter into agreements with corporations or buyers for the production of specific crops. This model often guarantees a market for the farmers’ produce.
• Government Role: Facilitation of contracts, monitoring compliance, and providing legal support.
3. Agribusiness Incubators
• Description: Establishing incubators to support startups in the agricultural sector, providing mentorship, training, and resources for innovative farming techniques.
• Government Role: Funding, infrastructure support, and partnerships with educational institutions.

The brinjal, eggplant or aubergine (French name) has originated in the Indian sub-continent and China (Thomson and Kelly, 1957, Purewall, 1957 and Martin and Rhodes, 1979). Brinjal is an important vegetable crop of the Far East, Bangladesh, India, China and the Philippines. Brinjal belongs to the family Solanaceae and is known under the botanical name Solanum melongena L. (2n = 24). There are 3 main botanical varieties under the species melongena(Chowdhury, 1976). The round or egg-shaped cultivars are grouped under var. esculenturn, the long slender types are included under var. serpentintumand the dwarf brinjal plants are put under var. depressum.

In many experimental situations, it becomes necessary to repeat an experiment over time, (for a number of seasons or years). This repetition (or replication) of the experiment broadens the scope of the experiment in the sense that our recommendations will be applicable for a number of seasons. In the case of agricultural experiments, for example, there may be present treatment x season interaction. So the results of a series of experiment, performed for different seasons with the same set of treatments, will have wider applicability.

We shall consider the simplest case of a repetition of experiments of identical structure for a number of seasons. Let us consider randomized block experiments with t treatments in r blocks and conducted in p seasons. The analysis of the experiment in a season is based on the linear model. Before attempting a combined analysis for the p experiments, it is necessary to perform the analysis for p experiments separately and interpret the results separately. It may be of interest to find out whether differences among the treatments are the same in the different seasons so that ‘ best ‘ treatment may be recommended for all seasons or whether different treatments are to be recommended for different seasons.

We next consider the analysis of the combined experiments considering the seasons as a random sample from the population of seasons. Analysis of Variance of series of experiments

22.1 Introduction

Tea is the most important non-alcoholic beverage gaining further popularity as an important “health drink”. It is consumed as a morning drink by 2/3rd of world population. Tea was initially used as a medicine and subsequently as beverage and now has proven to be a potential raw material for pharmaceutical industry. Tea is mainly consumed in the form of ‘fermented tea’ or ‘black tea’, ‘non-fermented tea’ or ‘green tea’ and ‘semi-fermented tea’ or ‘oolong tea’. Green leaves are also used as vegetables such as ‘leppet tea’ in Burma and ‘meing tea’ in Thailand. Tea leaves have more than 700 chemical constituents among which flavonoids, amino acids, vitamins (C, E, K), caffeine and polysaccharides are important to human health. The stimulating effect of tea is due to caffeine (1.25-4.5%). Per cup value of caffeine in tea is three and half times less than that of coffee and is less harmful than coffee. Importantly, the vitamin C content in leaves is comparable to that of lemon.

Conservation of released varieties requires a sound scientific and technical basis. There are two main strategies for conserving agricultural biodiversity, namely ex-situ and in-situ conservation, both of which are equally important. In-situ conservation refers to the maintenance of a species in its natural habitat. Exsitu conservation is the conservation of components of biodiversity outside their natural habitats. It is conserved in the form of seeds (seed gene bank), live plants (field gene bank), tissues (tissue gene bank), pollens (pollen gene bank) and DNA materials (DNA bank). 

Introduction

The cultivated strawberry is one of the world’s most important soft fruits. Fruit is technically known as an accessory fruit in that the fleshy part is derived not from the ovaries (achenes) but from the receptacle. Strawberries are a very nutritive fruit. It is a rich source of vitamins and minerals. Strawberry fruit contains about 0.5% pectin. The flavour of the fruit is due to the presence of volatile esters. Most of the fruits are consumed fresh and some are processed into jams, chutneys, squash, and other foodstuffs. It is used in large-scale ice cream making. The fruits are canned and shipped in frozen conditions to western countries. It is a fruit plant that is monoecious, has a short day, and grows quickly. Strawberry industries in America were started at the beginning of the 18th century, and today nearly 50% of the world’s production is in Europe.

Work simplification is the conscious seeking of the simplest, easiest, and quickest method of doing work. It describes the making of daily tasks easier in order to reduce strain or to decrease the amount energy required to complete an activity. Work simplification research consists of making motion and time studies of the work as it is being done, analyzing the work methods, developing the easiest and most effective way to do the task and putting the new method into use. Time and energy are closely related and if these are blended properly the work of the housewife will be much simplified.

oilless culture is a method of growing plants without soil. It is an artificial means of providing plants with support and a reservoir for nutrients and water. The simplest and oldest method for soilless culture is water culture or solution culture, where inorganic chemicals are dissolved in a vessel containing water to supply all the nutrients to plants. This method was originally termed hydroponics (water working) by W.F. Gericke in the 1930s. Over the years, hydroponics has been used sporadically throughout the world as a commercial means of growing both food and ornamental plants. Today, it is used widely in research facilities as a technique for studying plant nutrition.

Gravel or sand is sometimes used in soilless systems to provide plant support, and retain some nutrients and water. The retention of nutrients and water can be further improved through the use of sphagnum peat, vermiculite, or bark chips. These are the most commonly used materials, but other material such as rice hulls, bagasse (sugarcane refuse), sedge peat, and sawdust are used sometimes as constituents in soilless mixes.
