The informal associations of individuals who come close to seeking ways to enhance their living conditions are known as Self Help Groups (SHGs). They are generally self-governed and peer-controlled. An NGO or Agency usually governs people of comparable economic and social backgrounds to resolve their issues and improve their living conditions. It is a local committee of 10 to 20 women or men between 18 to 40 years. It acts as an intermediary financial committee. Self-help groups are a gaggle of each person on daily wages, and among that group, one person collects the cash and provides the case desired to the person in need.

Social media are electronic communication platforms that allow users to interact, create, share, retrieve and exchange information and ideas in different forms.

Social media refers to the means of interactions among people in which they create, share, and/or exchange information and ideas in virtual communities and networks.

There are many forms of social media including blogs, micro-blogs, wikis, social networking sites, photo-sharing sites, instant messaging, video-sharing sites, podcasts, widgets, virtual worlds, and more. Ex: Facebook, Twitter, Instagram, LinkedIn and Youtube etc.,

Role of social media in Transfer of Technology

Natural farming in India is witnessing growing acceptance, driven by concerns over environmental sustainability, soil health, and human well-being. To accelerate this transition away from chemical-intensive practices, both central and state governments, along with NGOs, have initiated comprehensive support systems that include policy frameworks, training, financial aid, and market facilitation.
A cornerstone of India’s natural farming policy is the Bharatiya Prakritik Krishi Paddhati (BPKP), launched under the Paramparagat Krishi Vikas Yojana (PKVY). This centrally sponsored scheme empowers states to implement natural farming by offering financial and technical assistance. States like Andhra Pradesh, Himachal Pradesh, Gujarat, and Maharashtra have led in adopting cluster-based natural farming models with large-scale training and demonstration programs.
Farmer training is central to adoption. Institutions such as Krishi Vigyan Kendras (KVKs), agricultural universities, and NGOs conduct extensive workshops on techniques like Jeevamrit, mulching, intercropping, and water conservation. Learning is made accessible through practical exposure, model farms, and local-language manuals, supported by digital tools like mobile advisories and community radio.
Support mechanisms include input subsidies for cow-based formulations, certification under Jaivik Bharat, and marketing linkages. Farmer Producer, Organizations (FPOs) facilitate input procurement, processing, and branding, while digital platforms improve market access and price realization.

Organizations Indebtedness Towards Society

The organizations in the present world operate as an open system by having ongoing interactions with the society for their existence and effective functioning. There is an interdependence between corporations and societies and as such, company’s activities have a direct impact on the communities with which they work.  As a part of such interactions, the organizations use valuable resources of the society, for producing goods and services, which are exchanged with the customers for a profit margin. Due to these exchanges, the business organizations take away the profits reflecting the debt they owe to the society and the world.

Abstract

Deserts cover about one fifth of the earth’s land surface. Most of hot and dry deserts are near the Tropics of Cancer or the Tropics of Capricorn. Cold deserts are near the Arctic part of the word. Deserts are of two types: Hot and Cold. Some of the important among them are given in Table 1. Spread over an approximate area of 74,809sq km, the cold desert area in India covers 12 out of 131 desert blocks. Leh and Kargil districts of Ladakh in Jammu and Kashmir and Lahual and Spiti along with some part of Chamba and Kinnaur districts of Himachal Pradesh comprise this cold desert area (Fig 1). Similarly, their physiographic location and the consequent geomorphic processes shall unfolding in the region lend to this entire region a largely similar texture. In terms of area, the cold desert of Spiti may be too tiny as compared to the seven major cold deserts of the world (Table 1), but in terms of its high mountains, extreme climate and poor economic conditions of the people, it is one of the most scourged areas on the earth. Located in the interior of continents, away from any source of moisture, cold desert manifest resemble ecological verity and biological diversity. Their geographic remoteness and unfriendly climatic conductions greatly constrain economic growth and development. Envirmental degradation, which is on increase, is an additional cause of concern.

Definition of terminologies and concept

Variables: Variables are the characteristic, number or quantity which increases or decreases over time and takes different values in different situations. Variables are those, whose value varies according to the situations. For example, maize yield, Stover, fertilizer, labor, land, pesticides, etc.
 
Dependent variable: Variables whose value is dependent on independent variables. These variables take different values only in response to independent variables. Yield of maize is dependent on amount fertilizer, fertilizer application methods, labor, pesticides etc. So in this case maize yield is dependent variables while amount fertilizer, fertilizer application methods, labor, pesticides are independent variables. However in other situation, maize yield can be used as independent variables also.

Before the invention of N fertilizer, mineralization of organic N ( present in dead plants and animals or manure) was the main method used to obtain ammonium and nitrate nitrogen. Mineralization is conducted by soil microbes resulting in ammonium ion. Most Nitrogen is absorbed by plants in the form of Nitrate (NO-₃). Ammonium is converted to Nitrate with the help of  soil bacteria. Nitrogen is a very mobile element and is easily lost from the soil. Ammonium (NH₄+) can be converted to Ammonia (NH₃). The gaseous ammonia can be lost to the atmosphere.  Nitrate can be lost through denitrification. Nitrate nitrogen is reduced to nitrous oxide (N₂O), elemental nitrogen (N₂) and nitric oxide (NO). All are volatile. Denitrification occurs under conditions of high water availability and temperatures higher than 10^ºC.

PLANT NUTRITION

Plants use inorganic minerals for nutrition, whether grown in the field or in a container. Complex interactions involving weathering of rock minerals, decaying organic matter, animals, and microbes take place to form inorganic minerals in soil. Roots absorb mineral nutrients as ions in soil water. Many factors influence nutrient uptake for plants. Ions can be readily available to roots or could be “tied up” by other elements or the soil itself. Soil too high in pH (alkaline) or too low (acid) makes minerals unavailable to plants.

Food adulteration is a global issue, and because there are insufficient regulations and oversight, developing nations are more vulnerable to it. But in many nations, food adulteration has gone unnoticed. Contrary to popular assumption, milk adulterants can, regrettably, present major health risks that result in fatal diseases. Modern milk adulteration involves increasingly complex techniques, necessitating state- of- the- art research to identify the adulterants. Because milk contains so many nutrients that are needed by both adults and infants, it is referred to as the ideal food. In terms of protein, fat, carbohydrates, vitamins, and minerals, it is among the best sources. Regretfully, milk adulteration is a very common problem worldwide. Potential causes could be the gap between supply and demand, the perishable nature of milk, the low purchasing power of the consumer, and the absence of appropriate detection tests. Because there is insufficient oversight and inadequate law enforcement, the situation is substantially worse in developing and underdeveloped nations. While quantitative detections of adulterants in milk are varied and complex, qualitative detections can be carried out simply using chemical reactions. The type of quantitative detection methods used depends on the milk’s adulterants.

Typical Adulterants in Milk

The addition of vegetable protein, milk from different species, whey addition, and watering are the main adulterants in milk that are known to be economically motivated. There is no serious health risk associated with these adulterations. Some adulterants, though, are too dangerous to ignore. Urea, formalin, detergents, ammonium sulfate, boric acid, caustic soda, benzoic acid, salicylic acid, hydrogen peroxide, sugars, and melamine are a few of the main adulterants in milk that have been shown to have serious negative health effects.

Abstract

Experiments on micro irrigation and fertigation system were conducted under four agronomic conditions viz. pot culture, a young conventionally planted apple experimental block, a high density experimental block and a conventionally planted bearing apple orchard. Direct correlation was observed between growth and micro irrigation treatments of 40% and 60% depletion of soil moisture at field capacity (FC); allowing depletion up to 80% of FC was found to be detrimental causing permanent damage and mortality.  Two doses (low and high applied at 10 weekly intervals) of fertigation were tried and were found at par with each other.  In fact, accumulation of N in soil was observed when applied at high dose after the third application whereas in case of applications at low dose a steady high N level was maintained throughout the growing season.  Observations on physiological parameters revealed better performance by the micro irrigated and fertigated trees.  Powdery mildew in apple could also be affective controlled by pesticide delivery through the fertigation system; however, some pesticides were found to affect the growth of the apple trees.  Fertigation has found to reduce fertilizer application by 95% in apple orchards opening further possibilities of reduced chemical pollution in cultivated soils and agricultural produce.

Crop growth rate (g m^_-2 day^_-1)

Crop Growth Rate is referred to a whole crop, so you need to consider the area of the ground where crop is present. It is measured as mass increase in crop biomass per unit ground area per unit time.
Equation for that is, CGR= W₂-W₁ / t₁-t₂

Vacreation: The pasteurization of the milk or cream under reduced pressure by direct steam is called vacreation.

Vacuum: The state of negative pressure. It is equal to atmospheric pressure minus absolute pressure.

Vacuum cooling: A technique of cooling vegetable (leafy vegetables, asparagus, brussels sprouts) having a high surface to volume ratio; rapidly and uniformly by boiling off some of their water at 1⁰C and at low pressure (5 mm of Hg) into a sealed container. The produce is cooled by evaporation of water from the tissue surface and is more rapid than hydro cooling.

Introduction

Lentil is one of the important Rabi pulses. It is one of the oldest pulses crops and the most nutritious of the pulses. It has the potential to cover the risk of dryland agriculture. It is also used as a cover crop to check the soil erosion in problem areas. It is mostly eaten as ‘dal’. Lentil can also be used as green fodder. Its straw is also used as cattle. Being a leguminous crop, it restores the soil fertility.

Area of cultivation

Lentil is mostly cultivated in the northern and central parts of India. The important lentil growing states are Madhya Pradesh, Uttar Pradesh, Bihar, West Bengal, Orissa, Haryana, Rajasthan, Punjab and Assam. Uttar Pradesh and Madhya Pradesh together contribute 78% towards total national area as well as production.

Climatic requirements: Lentil requires cold climate during growth and warm temperature at the time of maturity. It can tolerate cold and frost winter up to great extent. The optimum temperature for growth is 18-30 degree centigrade. Excessive drought and/or high temperatures during the flowering and pod-fill period also reduce yields.

Soil: Lentil can be grown on a variety of soils such as light loams; alluvial soils and black cotton soils. This crop is also suited to the poorer types of soils, low lying areas such as paddy fields. Lentil does not tolerate flooded or waterlogged soils. Good drainage is required, because even short periods of exposure to waterlogged or flooded field conditions kill plants. A soil pH near 7.0 is best for lentil production. Acidic soils are not fit for growing lentil.

9.1 Introduction

The rapid growth of industrialization and population significantly affect on the demand of ethanol as an alternate fuel. Generally, conventional crops like sugarcane and corn become unable to meet the demand of bioethanol, due to their primary role in food and feed. Therefore, lignocellulosic biomass from agriculture waste is attractive precursor for bioethanol production. Biomass is renewable organic material, abundant and cost effective. Ethanol production from agriculture waste has been projected an economically attractive option for industrial sector. However, sugar and starch derived ethanol have a more theoretical yield as compared to lignocelluloses, theses sources are insufficient for bioethanol production. The major agricultural wastes including rice straw, corn straw, wheat straw and sugarcane bagasse etc. can subsequently used for ethanol production. Rice straw has a highest worldwide potential for bioethanol production (205 giga liter) followed by wheat straw (104 giga liter), corn straw (58.6 giga liter), and finally for sugarcane bagasse (51.3 giga liter)¹.

A bio fuels is environmentally friendly options for power generation. Most of the fossil fuels are biological in nature. These are plant forms that, typically, remove carbon dioxide from the atmosphere and give up the same amount when burnt. The bio fuels are therefore considered to be “CO₂ neutral”, not adding to the carbon dioxide level in the atmosphere. The type of bio fuel used will depend on a number of factor, chief amongst them being the available feedstock and the energy that can be used locally.

India import 70% of the oil it uses, and the country has been hard by the increasing price of oil, uncertainty and environmental hazards that are concerned with the consumption of fossil fuels. In this context, bio fuels constitute a suitable alternative source of energy for India. There are two examples of bio fuels are Ethanol and Bio diesel (Renewable Diesel)

Ethanol can be made from biomass material containing sugar, starches, or cellulose (starch and cellulose are complex from of sugar)

Introduction

Entrepreneurship assimilates a very decisive dynamic dimension in a modified form through the globalisation progression into the Indian economic system. The core strength of economic development and economic growth in all underdeveloped and developing nations around the world is only due to the presence of entrepreneurial activity. A successful entrepreneurial approach plays a crucial role in the progress of industrial, manufacturing and service sectors and the development of agriculture. The government of most developing countries have invested much effort and resources in the past to enrich entrepreneurship (Oni and Daniya, 2012). According to a recent study, Saudi Arabia has been attempting to build a ten-year innovation and efforts entrepreneurship programme starting the year 2010. Similarly, in Malaysia, the government guided to set up of several technologies through the growth of technological know-how in entrepreneurship.
