Introduction

Bioremediation can be defined as elimination, attenuation or transformation of polluting or contaminating substances by the use of biological processes, to minimize the risk to human health and the environment. Bioremediation of contaminated soil and water uses microbes (e.g. bacteria and fungi) to convert pollutants to harmless or more environmentally acceptable products and minimizes the risk to human health in a natural or managed process.

Introduction
In the ever-evolving landscape of agricultural extension education, the need for dynamic and interactive training approaches has become paramount. Traditional training methods often focus heavily on theoretical content with minimal engagement. To bridge this gap, EEI Hyderabad has adopted a scientific and structured approach to training delivery. This initiative focuses on digital integration, experiential learning, and robust evaluation techniques to enhance knowledge retention and practical application among participants.
About the Technologies Addressed
The initiative leverages various digital tools and scientific models to enhance training effectiveness. These include:
• Online tools (13 stages): Used for participant registration, need assessment, evaluation, and feedback collection.
• David Kolb’s Experiential Learning Cycle: Ensuring hands-on learning through experience, reflection, conceptualization, and application.
• Kirkpatrick Model of Training Evaluation: A four-level approach to measuring training effectiveness through reaction, learning, behavior, and results.
• Simulation Exercises and Management Games: Enhancing decisionmaking skills and real-world problem-solving.
• Quizzes and Role Plays: Encouraging active participation and knowledge reinforcement.
• Fishbowl Technique and Focused Group Discussion: Facilitating peerto- peer learning and critical thinking.

2.1 Introduction

Rain and snow are the two chief sources of water of the earth. In-situ conservation of rainwater helps the plants to meet some of their consumptive uses directly. Not all the amount of rainwater that falls at a point is conserved by the soil reservoir to support the plant growth. Some part of it flows over the soil surface as surface runoff and some seeps down as infiltration and finally adds to the under ground reservoir. Therefore, rain or snow, which is not used directly by the plants, becomes a potential source of either surface or ground water for irrigation. In areas with extreme low temperature, snow contributes major source of water supply wherever, in humid and sub humid regions, rain is the principal source. Precipitation, rain or snow, is the first stage of the continual cycle of water in its round from atmosphere to the earth and return by evaporation from water bodies, snow surfaces and land surfaces. The continual cycle of distribution of water is governed by the process called as hydrologic cycle. Thus, precipitation or atmospheric water is the first form of water above the earth’s surface, the second form being the surface water on earth and the third form is the subsurface water or underground water. The study of occurrence, distribution and circulation of precipitation through the unending hydrologic cycle forms the basic part of study of hydrology. As mentioned above, the part of precipitation that is not used by the plants in-situ flows over the soil surface as runoff and contributes to either surface or ground water supply.

Gausalas

Recognizing the potential of Gaushalas (about 10000) in the country which were engaged in rehabilitation of disowned cattle, the government of India in 1952 set up the Central Council of Govsamvardana (CCG). Some of these gaushalas were providing quality indigenous / crossbreds / heifers / bulls at many places like Nasik, UrliKanchan, Amirtsar, Indore and Ahmednagar. One gaushala at Bombay had completed a century of devoted work in 1986 and had established two institutes, one for research and another for fodder research and grassland development. The Sabarmathi Ashram gaushala founded in 1915 by Mahatma Gandhi near Ahmedabad is now being managed by NDDB and has a training center for AI service including embryo transfer.

Traditionally, remote sensing encompasses a wide array of technologies and methods used to gather information about objects, areas, or phenomena without direct physical contact. This includes devices like seismographs, fathometers, radar systems, and more. These tools enable us to observe and measure various aspects of the environment from a distance.

However, in contemporary contexts, when we talk about remote sensing in a more specialized sense, we often refer to the use of satellite and aerial-based systems to capture and analyze electromagnetic radiation reflected or emitted from the Earth's surface. This form of remote sensing has become incredibly valuable in fields such as environmental monitoring, urban planning, agriculture, forestry, and disaster management, among others.

Modern remote sensing techniques leverage sensors capable of detecting specific wavelengths of electromagnetic radiation, such as visible light, infrared, and microwave radiation. By analyzing the patterns and intensity of this radiation, researchers can derive valuable information about the Earth's surface features, including vegetation cover, soil moisture, land use, and changes over time.

Lithological interpretation of igneous rocks involves the identification and description of the different types of rocks that form as a result of the cooling and solidification of magma or lava. Igneous rocks can be classified based on their mineral composition, texture, and the way they formed. Here are some of the common types of igneous rocks and their characteristics:

1. Basalt

Basalt is a dark-colored, fine-grained rock that forms from the rapid cooling of lava. It is typically composed of minerals such as pyroxene, plagioclase feldspar, and olivine.

Basalt is a common extrusive igneous rock formed from the rapid cooling of basaltic lava. It is typically dark in color, ranging from black to dark gray, and has a fine-grained texture. Basalt is composed mainly of plagioclase and pyroxene minerals, with smaller amounts of olivine, magnetite, and other minerals.

Basalt is found in many parts of the world, including the oceanic crust, volcanic islands, and some continental regions. It is also used as a construction material, such as in road paving, because of its durability and resistance to weathering. Additionally, basalt fiber is used in various applications, including reinforcing materials in composites, insulation, and other industrial uses.

Basalt in India: Basalt is a type of igneous rock that is commonly found in India. It is a dark-colored, fine-grained rock that is rich in iron and magnesium minerals.

ABSTRACT

Losses and benefits in agricultural production are associated with various weather parameters. So prediction of weather systems in different spatial and temporal scale over the Indian region therefore assumes considerable socio-economic importance. Meteorological information also plays an important role in the following operations in agriculture. The meteorological services can help the farmers & the planners exploit the potential of good weather and minimize the impact of bad weather as there exist tremendous opportunities for applications of meteorology in both day to day and long term planning in agriculture and such applications could contribute substantially to promote sustainable agriculture and poverty alleviation and the management of agrometeorological data is the key to these applications. Therefore, the area and input intensive agriculture is leading us into an era of unsustainable agricultural growth as the crucial components of sustainable agricultural production and distribution system such as integration of natural biological cycles and controls; protection and renewal of soil fertility and the natural resource base; optimization of the use of nonrenewable resources and of on-farm & off- farm inputs; ensuring dependable farm income. Hence, the meteorological information may help the farmer make the most efficient use of natural resources, with the aim of improving agricultural production both in quantity and quality. It becomes more and more important to supply meteorological information blended with weather sensitive management operations before the start of cropping season in order to adapt the agricultural system to increased weather variability. Subsequent to this, weather forecast based Agro-meteorological advisories become vital to stabilize their yields through management of agro-climatic resources as well as other inputs such as irrigation, fertilizer and pesticides. The main emphasis of the existing AAS system is to collect and organize climate/weather, soil and crop information, and to amalgamate them with weather forecast to assist farmers in taking management decisions. This has helped to develop and apply operational tools to manage weather related uncertainties through agro-meteorological applications for efficient agriculture in rapidly changing environments. Hence, weather information and advisories have assumed greater significance under the increased variability in the changing climate. Thus, Weather forecasting and advisory has become an indispensable aid for sustainable agro-transformation

Natural resources are the resources present naturally in the environment. These resources are used by human being for their survival. Minerals, building stones, forests, and various energy resources are known as natural resources. Natural resources have been extracted and utilized since ancient times but as the population increased, the demand of natural resources are increasing day by day.

Polysaccharides comprise several monosaccharide units (more than ten) linked by glycosidic bonds; therefore, they are high molecular weight carbohydrates. They are also called polyanhydrides of simple sugars. The most common monosaccharide unit of polysaccharides is D-glucose. The polysaccharides may differ in their monosaccharide units, molecular weight, chain nature, glycosidic bond types (alpha, beta), and linkages (1-2, 1-3, 1-4, or 1-6). They are tasteless, colorless, amorphous powders that are a little water-soluble. Some may form colloidal solutions. The polysaccharides provide structural stability (structural polysaccharides) to cells, prevent cells and tissues from drying out due to their water-binding properties, and reserve food for the future. Reserved polymeric carbohydrates are osmotically less active and can be stored in large quantities within the cell.
The right and left end of polysaccharides, respectively, are called the reducing and non-reducing ends. Based on the functional aspects, they are grouped in two ways.
• The first way depends on its digestibility—1. Nutrient polysaccharides are (digestible) starch, dextrin, and glycogen, and 2. Structural polysaccharides are (indigestible), chitin and cellulose.
• The second way, depending upon the constituent monosaccharide units, they are 1. Homoglycans (same units), and 2. Heteroglycans (different units).

THE DECLINE OF A COLONIAL CAPITAL TOWN

The Post Independence Scenario

It is believed that it takes more time to build and less to demolish, but strangely, in case of Allahabad, it took less time to build but much more to ruin it. As discussed in the last chapter, the peak was reached in about 34 years from 1868 to 1902, the period from 1903 to 1942 being the most constructive years in the history of Allahabad. From the inception of the High Court in 1868 to the formation of the Muir Central College in 1872, to being the capital of the provinces in 1902, Allahabad was regarded as a front runner in the field of Education and Culture.

The city regarded as a ‘production house’, nurtured talent and produced academicians and administrators, who contributed immensely in the process of nation building. The scenario after 1947 however changed drastically, it seemed, as if the city of Allahabad had exhausted its definite role in the freedom struggle, serving only as a preparatory ground which guided young minds to face the future with confidence. Its literary associations, libraries, university and other schools created an intellectual environment which propelled young talents to national fame. The civil services examinations were successfully cleared by many students of the university in those times, this was a result of quality education and an intellectually surcharged environment.

Independent India had lot of promises to fulfill and great expectations from the citizens. Delhi, the capital of Free India, was the focus of these activities. The emergence of new power centers and subsequent development of business and industrial centers, namely, Mumbai, Kolkata, Chennai and later Bangalore, shifted the focus of development from regional, small cities to these new centers. This quantum jump, saw cities of the like Allahabad, Lucknow, Varanasi, trail behind, as they were suddenly reduced in the current perspective and referred to as places in a historical perspective. Post Independence phase created huge opportunity for talented people, academicians, politicians, members of the judiciary, were asked to participate in the running of the nation. Allahabad’s role probably at this point of time, around 1947, seemed to be receding and the city was beginning to be ignored and conveniently forgotten. It slowly became a museum, with only old tales to tell.

This chapter discusses the decline of Allahabad, particularly institutional decline and also traces the earlier efforts in planning of the city. It is here we look for grey areas which would help in finding the exact causes of the physical decline that beset the city.

Research: The word research is composed of two words “Re” and “Search”.

“Re” - ‘Again or over again or a new’.

“Search” - ‘To examine closely and carefully’ or ‘to test and try’.

Research is a careful, systematic, patient study and investigation in some field

of knowledge undertaken to establish principles / policies.

Science: It is a systematized knowledge derived through observation,

experimentation or any other systematic method or procedure in order to

determine the nature of phenomenon or process being studied or the causes

behind specific events.

Research Methodology: The study of conducting research is research

methodology.

Pure/Basic/Fundamental Research: Gathering, knowledge is termed as

‘pure’ or ‘basic’ research. Just to gather knowledge in order to formulate or

generalize theories or policies. Pure research involves developing and testing

theories and hypotheses that are intellectually challenging to the researcher but

may or may not have practical application at the present time or in the future.

Abstract

Plantbreeding is an ancientart practiced throughselection ofplants fordesirable traits. Over a period of time it has evolved into scientific discipline with various methodologiesbasedon theories and principles ofgenetics. Since the rediscovery of Mendel’s law, there has been accelerated increase in yield of various crop plants due to development of high yielding varieties. Conventional approaches of following phenotypic selection from a variable population in early generation followed by yield testing in later generations have been highly successful in most of the crop species. This coupled with hybrid varieties led to significant increase in food-grain production during later half of the 20^th century. At present manycrops are facing yield plateau asthey have reached their maximum genetic potential. The growing condition is also deteriorating due to changing climate. There is an urgent need among breeders to utilize full arsenal of techniques available to them to sustain crop productivity. Molecular markers and marker assisted selection has come as a boon to the breeders to increase the efficiency ofselection in early generation breeding especially for traits whose phenotypic evaluation is difficult. Further, transgenic technology has the potential to incorporate genes from diverse sources, thus enriching the gene pool from which breeders can search for specific traits. Although at present there is skepticism about transgenic crops among public but this may become a viable strategy in future.

1. Genes and Disease

When various plants such as rice, wheat, tomato and apple are infected with pathogens and cause disease, pathogens are generally different for each host plant type.

Venturia inaequalis, the fungus that causes apple scab, only affects apples. Fusarium oxysporum f. sp. lycopersici which causes tomato wilting, only affects tomatoes and so on.

It is the presence in the pathogen of one or more genes of pathogenicty, specificity, and virulence to the respective host that enables disease development in the host.

1.0 INTRODUCTION

The most significant factors distinguishing organic farming from eco-farming are the existence of production standards and certification procedures. Certification of organic farming is the procedure by which a written assurance is given by the certification agency that a clearly identified production or processing system has been methodically assessed and conforms to the specified requirements. It is a process certification rather than a product certification. Certification and labelling is usually done by an independent body to provide a guarantee that the production standards are met.  In case of organic products, certification is an acknowledgement that the products are produced according to organic production standards of certification bodies or associations or of the country. Organic production system is a land use system in accordance with set standards to the location specific conditions by integrating practices that foster cycling of resources, promoting ecological balance and conserve biodiversity. The prime principles of organic farming are,

Globally, agriculture productivity is challenged by abiotic and biotic stresses, but abiotic stresses in particular (Gong et al., 2013) affect spreading of plant species across different environmental zones (Chaves et al., 2003). The changing climate is expected to worsen abiotic factors globally and adaptation strategies need to be established for target crops to specific environments (Beebe et al., 2011). Connect between different stress factors will likely surge harm to crop yields (Beebe, 2012). Soil salinity is a major environmental constraint to agricultural productivity (Greenway and Munns, 1980; Rhoades and Loveday, 1990). High concentrations of different types of salts, including chlorides, carbonates, and sulfates of magnesium, calcium, potassium, and sodium, characterize different saline soil areas around the world. Moreover, for each type of naturally occurring salinity, constantly changing environmental conditions, such as temperature and precipitation, as well as agricultural practices cause rapid modifications in levels of salinity and salt distribution patterns. Sodium and chloride are the predominant ions in the vast majority of saline areas.

During evolution, various species of plants, known as halophytes, readapted to life in high-salinity environments, but a large majority of plant species grown in non-saline areas are salt-sensitive (referred to as glycophytes). These glycophytic plants, including the majority of crop species, differ greatly in their tolerance to salt stress (Greenway and Munns, 1980; Flowers and Colmer, 2008).

Over the period of time, the dairy sector has added distinct significance to growing Indian economy. India contributes nearly 19.54% to the global annual milk production with an impressive upliftment of 3.6% in yearly production rate as per the latest available data from FAO International.

Agro-inputs are either biological or chemical or inorganic compounds used in the production of agricultural and allied products. Some of the agro-inputs used in India are :

• In-organic fertilizers
• Pesticides which include insecticide, fungicide, nematicide and herbicide
• Seeds which include varieties, hybrids and genetically modified plant materials
• Vegetatively propagated planting materials
• Bio-fertilizers
• Organic inputs which include compost, vermicompost, enriched farm yard manure, oil meals and farm yard manure
• Bio-pesticides
• Bio-control agents
• Plant Growth regulators
• Micro-nutrients
• Farm machinery and agricultural tools and implements
• Animal feed
• Poultry feed.

The production and distribution of above mentioned agricultural inputs create agri-business opportunities. The agricultural input production inputs and distribution firms may be big companies like Madras Fertilizers, SPIC, FACT, EID Parry, Monsanto, Syngenta or MAHYCO and the like. They may also be small business firms like vermicomposting, coir pith decomposing.

Nutritional significance of tannins in feeds and fodders

Tannins are widely distributed in many types of browse plants, tree leaves, forages and feed ingredients. The structure of tannins are not completely well defined but they are polymers of phenolic and aliphatic hydroxy compounds. Although tannins and related polyphenols are considered as protein binders and, protease and cellulolytic inhibitors, they can also exert beneficial effects on rumen fermentation. There are two forms of tannins viz., hydrolysable and condensed. Hydrolysable tannins are considered to have less deleterious effects on protein digestion since these types of tannins might get hydrolysed under acidic gastric condition and release bound proteins. Attempts have been made to utilize this to advantage in protection of proteins from rumen degradation.The condensed tannins are resistant to hydrolytic degradation. The reduction in digestibility due to condensed tannins is not clear whether it is due to specific interference with cellulases or precipitation of proteins.

Certain feed ingredients have been incorporated as a source of tannins, in the diets of ruminants to benefit ruminal fermentation and performance. Inclusion of Bengal gram husk as a source of tannins in the diet of sheep prevented potentially digestible carbohydrate in the rumen, but digested post ruminally (Sreerangaraju et al., 2000).

Rural Development: The economic betterment of people as well as greater

social transformation. The efforts for rural development comprises the direct

and indirect involvement of people at the grass root level for development of

agriculture/animal husbandry, industry, communication, education, health and

allied sectors.

Democratic Decentralization: To ensure people’s participation in rural

development programmes, democratic decentralization has been the core

principle of the government since 1957. In the process, people’s participation

in all developmental activities has been the unique phenomena to find out the

solutions of their problems.

Panchayat Raj: On the principle of democratic decentralization, Panchayat

Raj institutions were launched in 1957 as per the recommendations of Balwant

Rai Mehta Committee. Under this, the government has derived its authority

from the people, and distribute to some extent to the people for decision and

action at the local level called Panchayat Raj.
