Introduction

Agriculture is the measure livelihood of tribals in India. Indigenous Tuber crops, like Elephant foot yam (Amorphophallus) and Dioscorea play a valuable role to uplift the socio and economic status of people of tribal areas (tribal farmers) in terms of nutritional security and livelihood. In every year rural India subjected to wide spread of poverty, malnutrition, infant mortality rate etc. Ecological degradation, climate change, erratic rainfall and drought are the principal causes of food insecurity in these tribal areas resulting migration, periodic starvation and deaths. Therefore under erratic climate, tuber crops like Amorphophallus and Dioscorea, played a crucial role as life support crops to combat hidden hunger. Tuber crops are the traditional crops cultivated in order to meet the food requirements and give economical sustainability to the people. After cereals and legumes, tuber crops constitute a major staple or subsidiary food for all. Amorphophallus paeoniifolious and Dioscorea alata, important tropical tuber crops are excellent dietary staple for low-income consumers in tribal areas of Odisha state, better opting tuber crops cultivation rather than forest produces.

Introduction

Cotton is a fiber crop of Malvaceous family. There are four cultivated species of cotton viz. Gossypium arboreum, G. herbaceum, G. hirsutum and G. barbadense out of which G. hirsutum is the predominant species contributing about 90% to the global production. In India all the above four cultivated species are grown on commercial scale as a kharif crop. India is the largest producer as well as consumer of cotton in the world. The major cotton growing states of India are Maharashtra, Punjab, Haryana, Rajasthan, Uttar Pradesh, Madhya Pradesh, Gujarat and parts of Andhra Pradesh & Karnataka. In Odisha cotton cultivation is an up-coming activity. Many of the western belt farmers, mainly from Rayagada, Bolangir, Kalahandi, Nabarangpur, and Nuapara districts have been taking cultivation of this cash crop. According to the report of Odisha economic survey, 2018-19 a total of 1.45 lakh ha area was cultivated in 2017-18 producing 3.65lakh bales of cotton. In Rayagada district cotton is cultivated in 9 blocks out of 11 blocks comprising an area of 35170 ha. For the year 2018-19 yield was 12.37 q/ha with production of 25.6 MT of cotton according to the data given by District agriculture office, Rayagada.

Agricultural production system has gone a long way in supporting the world’s food requirement. The projected estimates revealed that to meet the global population of about 11.3 billion in 2050, the global demand for cereal will increase by 60% (Rosegrant and Cline, 2003, Bengtsson et al., 2006). Agriculture is considered as the chief agent of environmental transformation. The unrestrained attitude of Homo sapiens towards the use of natural resource catalyzing the causes leading to global warming, has increased the challenges manifold to provide food security in a sustainable manner. Increased concentration of CO2 and other green house gases have resulted in an increase of 0.760 C in surface temperature globally since nineteenth century and the mean global surface temperature is predicted to increase by an additional 1.30C to 1.80C by 2050( IPCC, 2007). Sinha and Swaminathan (1991) reported that an increase of 20C in temperature could decrease the rice yield by about 0.75 t/ha in the high yield areas and a 0.5oC increase in winter temperature would reduce wheat yield 0.45 t/ha.

Startup India, the initiative of Government of India, was first announced by Honourable Prime Minister Mr Narendra Modi during his Independence Day speech on 15 August, 2015 and discussed elaborately again on 27 December 2015 in his radio address ‘Maan ki baat’ mentioning startup as new opportunities for the youth who want to set up new business or innovative projects. Indian Government lunched this ‘Startup India – Standup India’ campaign on 16 January 2016 with an intention to build a strong startup ecosystem for nurturing innovation and encouraging private investment.

v : Represents the volume of a gas.

p : Represents the pressure of a gas.

t : Represents the absolute temperature.

The law is represented by the relation writen as t v k. p ? where k is a constant.

1. Suppose the temperature varies and pressure remains constant then

2. Suppose the pressure varies and temperature remains constant then

In production one or a combination of the following relationship are commonly observed:

1. The law of constant marginal returns (productivity)

 2. The law of increasing marginal returns (productivity)

 3. The law of decreasing marginal returns (productivity)

18.1 Introduction

The farmers have limited resources and a number of enterprises/or enterprise combinations of crops and livestock to choose from. So, the question is how much of what to produce and with what technology. In other words, what combination of enterprises should be produced is expressed as.

23.1 Introduction

The following Frank Kright, the knowledge situation can be classified into the following logical possibilities:

23.2 Perfect Knowledge

There would be no need for farm management experts if knowledge was perfect. If there were so technology, prices and institutional behaviour would be known with certainty for any period of time in the nature. But the concept of perfect knowledge is a fallacious one and does not represent the real world situation.

24.1 Introduction

Linear programming is a budgeting technique which is more refined and systematic than conventional budgeting in determining the optimum combination of enterprises or inputs so as to maximise the income or combination of enterprises or the income or minimise costs within the limits of available resources. It may be defined as “The analysis of the problem in which a linear function of a number of variables is to be maximised or minimised when these variables are subject to a number of restraints in the form of linear inequalities”, In linear programming models, the objective of the typical farm i.e maximisation of net profit or cost minimisation is achieved through an optimal plan generated from its solution.

Prologue: The Issues

Farmers lose a significant portion of their income when their crops and products become infested with various insects, diseases and weeds, resulting in much lower crop productivity and lower actual yields than the attainable yield of crops. Yield losses due to pests, pathogens and weeds are responsible for 20-40% losses in global agricultural productivity. India reports crop losses of 20-25% annually due to pest infestations. Without the use of crop protection solutions, there could be a 78% loss in fruit production, 54% loss in vegetable production and 32% loss in cereal production. According to the Ministry of Agriculture, India loses INR 1.48 billion worth of agricultural production annually due to pests, weeds and plant diseases.

1. Markers: Easily identifiable features are called markers or marker features.

2. Types of marker

These markers are three types

2.1.Morphological markers: These relate to the size, shape, color and surface area of different parts of the plant.

2.2.Biochemical markers: Such markers refer to changes in protein structure. For example, isozymes and storage proteins.

Changes in philosophy about plant disease management

To achieve reasonable and sustainable results crop disease management philosophy should shift focus from

Management of pathogens (or insect vectors) to managing host plants.

A single goal of high productivity to multiple goals of high yield, efficiency, quality and safety.

Introduction

The study of fish health is crucial for understanding aquatic ecosystems and ensuring the well-being of aquatic species. This report provides a detailed account of a hands-on activity involving necropsy and health examination of fish. Through this practical experience, we aimed to gain insights into the common ailments affecting fish populations and develop skills in identifying pathological conditions.

The necropsy process involves the post-mortem examination of fish specimens, enabling us to observe and analyze internal organs, tissues, and external features. By combining practical techniques with theoretical knowledge, we seek to contribute to the broader understanding of fish health and disease.

Introduction

In the ever-evolving realm of fisheries and aquaculture, the infusion of molecular technology has become a beacon of hope, transforming the way we diagnose diseases and identify pathogens. Imagine it as a kind of genetic detective work that not only helps us understand the health of aquatic life but also empowers us to protect it. It all begins with the delicate dance of DNA extraction, a bit like teasing out the secrets locked within the cells of aquatic organisms. This biological treasure map, once unveiled, guides us through the labyrinth of diseases. Enter the PCR protocol for Carp Edema Virus (CEV) detection—a sort of molecular magnifying glass that allows us to zoom in on specific genetic footprints of trouble. It’s like deciphering a genetic code, helping us pinpoint potential issues swiftly.

Aim: To perform open and short circuit test on a single-phase transformer, to obtain equivalent circuit parameters.

Open circuit test

The core loss or iron loss i.e. the no-load loss in a transformer is determined by performing the no-load test at normal sine wave impressed voltage. Through the iron loss in a transformer is not governed by the supply being connected to primary or secondary side but when measuring this no-load loss.

It is usually more convenient and safer to supply the voltage to the low voltage side. This makes the test apparatus cheaper and becomes safer for the low testing personal. To determine the shunt branch parameter of the equivalent circuit, the primary side (L.V.) is connected to a normal supply voltage and rated frequency and secondary side (H.V.) is left open with care so that there is no possibility of coming in contact with any part of (H.V.) terminals. The wattmeter connected in the primary (L.V.), will then read the total hysteresis.

Aim: Determination of percentage regulation and efficiency of a single phase transformer by direct loading method.

Percentage regulation

When the load on the transformer is increased, the voltage drop in its primary and secondary windings also increases causing variations in secondary terminal voltage. The term voltage regulation of transformer means the change in secondary terminal voltage when full load is thrown off keeping supply voltage and frequency constant. It is generally expressed as percentage of no load terminal voltage for a desired power factor.

Aim: To perform Sumpner’s test (back-to-back test) on a pair of similar transformer and thus calculating efficiency of operation.

Sumpner’s test givens an effective way, to actually see the performance of transformers of large rating without loading them, at full load. This back to back test allows heat run test so that temperature rise and its rate can be analysed.

The two identical transformers are connected back to back as shown in figure such that their polarities are in opposition. To do this, two terminals of the secondary winding are connected as shown and the voltages between the other two are measured by exciting primaries.

Aim: To verify the relationship between the input and output voltage for 3-phase transformer connection in various ways:

A 3-phase transformer can be considered as a set of 3 single-phase transformer bank or as single unit of 3 phase windings. Since three winding are available in both primary and secondary side then there can be different types of connections and so far, different characteristics.

Aim: To obtain balanced two-phase supply from three-phase supply by Scott arrangement of two single-phase transformers.

The phase conversion from three to two phase is needed in special cases, such as in supplying 2-phase electric arc furnaces. Scott connection of two-single phase transformers is employed for conversion of a three-phase system to two phase system or vice-versa. Rating of one transformer should be 15% greater than that of the other, but in practical two identical transformers are used for interchangeability and spares. The 50% tap of one transformer (Main transformer) is connected to 86.6% tap of the other transformer (Teaser transformer). The secondaries for balanced supply system have equal number of turns.

Aim: To determine the Load characteristics (External characteristics) of self excited D.C. shunt generator.

If a dc shunt generator, after building up to its voltage, were loaded, its terminal voltage will drop. This drop increases if load increases. But this type of terminal drop is undesirable for a specified service. The relation between terminal voltage and load current is called external characteristics. Speed is to be kept constant. Reason for voltage drop:

Aim: To perform speed control of D.C. shunt motor by

1. Armature resistance control method.

2. Field (flux) control method.

This method is based on the fact that by varying the voltage available across the armature, the back EMF and hence the speed of the motor can be changed. This is done by inserting a variable resistance RC (known as controller resistance) in series with the armature as shown in Fig. (a).

Aim: To determine the Efficiency Vs Load characteristics (External characteristics) of D.C. shunt motor Swinburne’s method.

This method is an indirect method of testing a DC machine. It is named after Sir James Swinburne. Swinburne’s test is the most commonly used and simplest method of testing of shunt and compound wound DC machines which have constant flux. In this test the efficiency of the machine at any load is pre-determined. We can run the machine as a motor or as a generator. The iron and friction losses are determined by measuring the input to the DC machine at no-load. The machine is to be run as a motor at normal voltage and speed. The Swinburne’s method includes all the losses in the field circuit and winding which do not occur actually in the machine but the error introduced due to this is quite insignificant and still shows the accurate results. In this method of testing no-load losses are measured separately and eventually we can determine the efficiency.

Aim: Determination the equivalent circuit parameters of a single-phase induction motor.

1. No-load test.

2. Blocked rotor test.

The performance of a single-phase induction motor is generally studied either by double revolving field theory or by cross field theory, the former being simple and gives a clear physical understanding.

Aim

(a) Perform load test on 3-phase induction motor.

(b) Compute Torque, Output power, Input power, Efficiency, Input power factor and Slip for every load setting and to determine how speed, efficiency, power factor, stator current torque, and slip of an induction motor vary with load.

The load test on induction motor is performed to compute its complete performance i.e. torque, slip, efficiency, power factor etc. During this test, the motor is operated at rated voltage and frequency and normally loaded mechanically by brake and pulley arrangement from the observed data, the performance can be calculated, following the steps given below.

Aim: To study the effect of variation of field current upon the stator current and power factor with synchronous motor running at no-load, hence to draw V and inverted V curves of the motor.

With constant mechanical load on the synchronous motor, the variation of field current changes the armature current drawn by the motor and also its operating power factor. As such, the behavior of the synchronous motor is described below under three different modes of field excitation.

Introduction

Nanocomposites are materials that incorporate nanosized particles into a standard material matrix. The addition of nanoparticles can significantly improve properties such as mechanical strength, toughness, electrical or thermal conductivity. Typically, only a small amount of material (0.5-5% by weight) is required due to the effectiveness of the nanoparticles. A nanocomposite is a solid material that consists of multiple phases, where at least one of the phases has one, two, or three dimensions in the nanometer size range. The goal of the nanoscale phase process is to achieve synergy between different constituents. Nanocomposites represent a promising alternative to overcome current limitations of microcomposites and monolithics, and are becoming the materials of the future (Schmidt et al., 2002).

Introduction

Non-coding RNAs (ncRNAs) are RNA molecules that do not code for proteins. They are transcribed from DNA and can be categorized into two main types: long non-coding RNAs (lncRNAs) and small non-coding RNAs (sncRNAs). While sncRNAs are shorter than 200 nucleotides, lncRNAs are usually longer than 200 nucleotides. Non-coding RNAs have been found to play important roles in a variety of cellular processes, including gene expression, cell differentiation, and development.

Introduction

Though the potential benefits generated by the drip irrigation method are apparent, the adoption of drip irrigation is yet to be widely promoted across different regions and states in India. Several factors such as huge initial investment, small size of holding, lack of technical support, nature of cropping pattern, access to water and socio-economic conditions of farmers etc. (Namara et al, 2005, Suresh Kumar, 2012) are constraining adoption of drip irrigation. In some cases, even after the adoption of drip irrigation, the farmers, particularly, the small farmers have often discontinued use of drip irrigation for several reasons such as due to lack of maintenance, irrelevant cultural background, and unreliable water supply (Kulecho and Weatherhead, 2005).

Background and Technology Intervention

Andhra Pradesh is India’s fourth largest state in terms of area and fifth in terms of population. Its capital Hyderabad is one of the largest and fastest growing cities in Southern India occupying 650 square kilometers along the bank of Musi River. History says that, the fifth sultan, Muhammad Quli Qutab Shah established Hyderabad on the banks of Musi River in 1591 to avoid the acute water shortages experienced at Golconda during his rule. Today, due to rapid urbanization and increased economic activities, the river has become a receptacle of untreated domestic and industrial waste dumping out of Hyderabad. It is estimated that nearly 350 MLD (Million Liters a Day) of polluted water and sewage originating from the twin cities of Hyderabad and Secunderabad flow into the river. Though this river water which is at the downstream of the city remains highly polluted and considered a major disaster in Hyderabad, it is a significant resource for semi-arid and peri-urban population where the cultivation of fodder grass, paddy and vegetables have contributed largely to the household food security.

Background and Technology Intervention

Managed Aquifer Recharge (MAR) describes planned storage and treatment of water in aquifers which can provide cheapest form of new safe water supply for towns and small communities (British Geological Survey, 2006). It is a part of a groundwater manager’s tool which is useful for replenishing and re-pressurising depleted aquifers, controlling saline intrusion or land subsidence as well as improving water quality through filtration and chemical and biological processes. MAR can enhance volumes of groundwater abstracted through different package of measures and restore groundwater balance. It also plays a vital role in smoothing out supply and demand fluctuations, stabilizing over-exploited groundwater levels, reducing evaporation losses and runoff, maintaining environmental flows in streams and rivers, improving water quality and augmenting the reuse of waste and storm water. In recent times, MAR uptake has been very limited.

The results of Focus Group Discussions and Field Level Workshops (Tables presented at the end of toolkit) conducted with different stakeholders mentioned in the methodology revealed that, communication skills, soft skills, leadership development skills, personal and professional development skills followed by entrepreneurship development skills are more important and needed to perform job effectively at field level extension work (Table 1).

Agriculture is biggest user of water, accounting 70% of all withdrawals. It is major water-consuming sector due to intensification of agriculture (CWC, 2021). With changing climatic condition, demand of water will increase. Hence, conservation and efficient management of limited water has become the need of the hour for sustainable fruit production. Since per unit returns from horticultural crops are higher, their production system improves the net return of farmers and would impart resilience to aberrant weather (Meghwal et al., 2018). Therefore, immense opportunities for quality production of water-economizing horticultural crops. In arid and semi-arid regions, uncertain, erratic and scanty’ rains coupled with meagre irrigation facilities leads to low and unstable yields.

Vertical farming is a system of growing crops in multiple layers in skyscrapers, to maximize the use of land by having a vertical design, whereby plants, animals, fungi and other life forms are cultivated for food, fuel and fibre by artificially stacking them vertically above each other (Despommier, 2009; Kalantari et al., 2017). It is estimated that nine acres in a horizontal farm is equal to 1 acre in a vertical farm. The concept of vertical farming started during the mid 90s by Dr Dickson Despomier, professor of Public and Environmental Health at Columbia University

1.1 Introduction

Poultry is one of the fastest-growing areas of India’s agricultural industry, with an annual growth rate of around eight percent. Over a span of four decades, the chicken industry in India has seen a paradigm shift in structure and operation, transforming from a simple backyard occupation to a significant commercial agri-based enterprise. Constant efforts in upgrading, modifying, and using new technologies opened the path for the multiplication and diversification of poultry industries. The expansion is not just quantitative, but also qualitative, sophisticated, and productive. This transition has necessitated substantial expenditures and increases in breeding, hatching, raising, and processing. The rise of the poultry industry in India is also characterised by the expansion of chicken farms.

6.1 Introduction

The egg production in the country has increased from 78.48 billion in 2014-15 to 114.38 billion in 2019-20. India ranks 3rd in egg production in the world. Annual growth rate of egg production was 4.99 per cent during 2014-15, there after there has been a significant improvement in the egg production with 10.19 per cent growth registered in 2019-20 over the previous year. The per capita availability of egg was 86 per annum in 2019-20. Less than a generation ago the main supply of eggs was from small backyard unit. Processors, handlers, and distributors of eggs and egg products need an understanding of egg-production practices to cope more intelligently with problems of product quality and character

8.1 Introduction

Egg is a perishable product having short shelf life. The table eggs are of highest quality when they are laid. Preservation of eggs should start from the point of production itself.

The following practices are recommended as routine for the production of quality eggs on the farm.

1. Collection of eggs at least 3 times daily.

2. Using a clean receptacle with ventilated sides and bottom, preferably filler f lats.

11.1 Introduction

Egg contents may be contaminated via vertical or horizontal paths. In the former, bacteria may colonise the ovaries and/or oviduct, whereas in the latter, pollutants, such as faecal matter or dust, travel through the shell and colonise the membranes and yolk. The surface of a nest-fresh egg provides minimal protection against bacterial pollutants, resulting in the dominance of Gram-positive Micrococci in the shell microflora. Nonetheless, a variety of conditions have been demonstrated to either increase the survival of bacteria in the unfriendly environment of the egg’s shell surface or to impair the egg’s antimicrobial defence mechanism in other ways.

15.1 Introduction

In addition to serving as a means of reproduction, avian eggs are a staple meal in the diet of humans and include a natural balance of all the required components. However, eggs must overcome a few drawbacks in the current food market in order to compete for sales with an expanding number of other items. For instance, eggs are a delicate commodity that age-related quality reduction. Additionally, the intrinsic variability of the egg’s three primary parts—the shell, albumen, and yolk—does not meet the demands of contemporary customers for consistency. The successful sale of eggs depends on planned production techniques and effective quality control processes, both of which contribute to decrease this fluctuation.

16.1 Introduction

Successful egg production is highly dependent on sanitation and decontamination, and producing clean eggs is the most major element of egg sanitation. Egg contents might become contaminated either vertically or horizontally. The ideal option for small farms can be to keep hatching eggs in a hygienic area and incubate them as soon as possible without sanitation but it’s not the same kind in case for commercial producers need to get a poultry veterinarian guidance on the proper egg handling and sanitation program depending on their needs. There are several preharvest techniques used to minimize egg contamination, including immunization, feed additives, home sanitation, bacteriophages, and biosecurity.

25.1 Introduction

There has been a recent increase in the consumption of organic food, particularly in developed countries. Consumer awareness is growing in terms of organic food products in recent years as almost all the food ingredients are grown under intense production systems which utilize lot of chemicals and pesticides to control the pests and diseases. Organic farming can be defined as an approach to agriculture where the aim is to create integrated, humane, environmentally and economically sustainable agricultural production systems producing acceptable levels of crop, livestock and human nutrition, protection from pests and diseases, and an appropriate return to the human and other resources employed.

26.1 Introduction

The egg’s primary non-food purpose is to help the species reproduce. The quantity of eggs required for the hatching of chicks has increased significantly due to the substantial rise in meat consumption. The USDA has made a list of a few other non-food use for eggs.

Inedible eggs are often used as animal feed and plant fertilizers. Eggs are also fed to show animals, such as dogs and horses, to improve the glossy sheen of the fur coat. Industrial egg albumen is used in finishing several types of leather, notably coloured stock, and glazed. production of vaccines in chick embryos is one of the key uses of eggs, as per various researchers.

Introduction

In most developing nations, the primary method of managing insect pests on various crops is by synthetic insecticides. One of the fastest and most efficient ways to reduce insect populations is by chemical control where a farmer quickly achieves extraordinary results.

However, overusing pesticides indiscriminately and without proper research for longer periods of time led to a number of issues, including the risk of environmental contamination, loss of biodiversity, development of insecticide resistant pest populations, resurgence, outbreaks of secondary pests, increase in chemical inputs, toxicological hazards due to accumulation of pesticide residues in the food chain, etc.

Mesothelioma

• Arising from the mesothelial lining of serous cavities
• It is very difficult to differentiate from carcinoma, reactive mesothelial hyperplasia
• Round to polygonal cells
• Arranged mostly in clusters
• Centrally located hyperchromatic nuclei

Definition

Agricultural journalism is a specialized branch of journalism that deals with the techniques of receiving, writing, editing and reporting from information through the media like newspapers, periodicals, radio, TV, advertising etc. and the management processes connected with such production. It is the timely reporting and editing with words and photography of agricultural news and information for newspaper, magazine, radio and television.

It is otherwise known as Farm journalism

Farm journalism is very important for communicating with farm people. More and more of the extension staff’s writing is being read or listened to in newspapers, magazines, brochures, pamphlets, bulletins, circular letters, wall newspapers, and radio scripts. The written work makes working as a consultant with farmers more fascinating.

Principles of Farm/Agricultural journalism

India is a geologically diverse country with a wide variety of rock types. The major rock types found in India can be broadly classified into the following categories:

Igneous Rocks: These rocks are formed from the solidification of molten magma. They can be further divided into two types:

1. Plutonic (Intrusive) Igneous Rocks: Examples include granite, diorite, and gabbro. These rocks are formed deep within the Earth's crust and have a coarse-grained texture.
2. Volcanic (Extrusive) Igneous Rocks: Examples include basalt, andesite, and rhyolite. These rocks are formed on the Earth's surface from volcanic eruptions and have a fine-grained texture.

Sedimentary Rocks: These rocks are formed by the deposition and consolidation of sediments over time. They can be further divided into various types based on their composition and mode of formation:

1. Clastic Sedimentary Rocks: Examples include sandstone, shale, and conglomerate. These rocks are formed from the accumulation and lithification of fragments of pre-existing rocks.
2. Chemical Sedimentary Rocks: Examples include limestone, dolomite, and rock salt. These rocks are formed from the precipitation of minerals from water bodies.

Structural landforms are landforms that are created due to the underlying geological structures of the earth's crust. These structures can include folds, faults, and other features that have been formed due to the tectonic forces that have shaped the earth's surface over millions of years.

Examples of structural landforms include mountain ranges, plateaus, and rift valleys. Mountain ranges are formed due to the upliftment of the earth's crust along a fault line or due to the folding of the earth's crust. Plateaus are flat-topped landforms that are formed due to the upliftment of a large area of the earth's crust. Rift valleys are formed due to the stretching and pulling apart of the earth's crust along a fault line.

Denudational landforms, on the other hand, are landforms that are created due to the process of erosion and weathering. These landforms are formed due to the gradual wearing down of the earth's surface by natural forces such as wind, water, and ice.

Rock

A rock is a solid, naturally occurring substance composed of minerals or mineraloids. It is typically formed through geological processes, such as cooling and solidification of molten lava or magma, or by the deposition and compaction of sediment over time. Rocks are classified into three main types based on their origin: igneous, sedimentary, and metamorphic.

Igneous rocks: Formed from the cooling and solidification of molten lava or magma. Examples include granite, basalt, and obsidian.

Sedimentary rocks: Formed from the accumulation and compaction of sediment, such as sand, mud, or organic matter, over long periods. Examples include sandstone, limestone, and shale.

Metamorphic rocks: Formed from the transformation of existing rocks under high temperature and pressure conditions. They undergo changes in mineral composition, texture, and structure. Examples include marble, slate, and gneiss.

Rocks serve as the building blocks of the Earth's crust and are an essential part of the geological processes that shape the planet. They can provide valuable information about Earth's history, including the formation of mountains, the movement of continents, and the presence of ancient life forms. Rocks are also used in various practical applications, such as construction, road building, and the production of minerals and resources.

Geomorphological mapping is the process of creating detailed maps that illustrate the physical features of the Earth's surface, including landforms, soil types, vegetation, and water resources. These maps can be used to better understand the underlying geology and topography of a region, and can be used for a variety of purposes, such as land-use planning, environmental management, and geological hazard assessment.

Geomorphological maps are typically created using a combination of field observations, aerial photography, and remote sensing data. Field observations involve physically visiting a site and making detailed observations of the landforms, soil types, and vegetation. Aerial photography involves taking high-resolution photographs of the Earth's surface from an airplane or satellite, which can be used to create detailed maps of the area. Remote sensing data can also be used to create geomorphological maps, including data from satellites, radar, and LiDAR (Light Detection and Ranging) systems. These technologies allow scientists to gather data about the Earth's surface without physically visiting the site, and can provide highly accurate information about the topography, geology, and vegetation of an area. The resulting maps can be used for a variety of purposes, including land-use planning, natural resource management, and hazard assessment. For example, geomorphological maps can be used to identify areas of high risk for landslides, floods, or earthquakes, and can be used to develop strategies for managing these hazards.

1.1 Background

The aftermath of Green Revolution has contributed to both coercions and pollution, albeit, it saved human civilization from hunger, malnutrition and impoverishment. The beginning of GR era, with the prevailing objective and condition, has got less but few choices to go for intensive cultivation that invited chemical fertilizer, assured irrigation and farm mechanizations to make the 'magic gene' revolutionizing the production, productivity and livelihood security in agriculture as well.

The welcome of exotic genes into Indian agriculture has also triggered the silent oftraditional cultivars. Nevertheless, the quantum jump of an agriculture with a production of 55 million tons to 120 million tons during 70s, has contributed to make India self-reliant in food and we have been able to earn a new esteem in the global geo-political scenario by throwing away the 'begging bowl' called PL480.

Democracy is a system of government in which power is held by the people, either directly or through elected representatives. It is a form of government that allows for the free and fair participation of citizens in the decision-making process of the country. In a democratic system, all citizens have the right to vote and participate in the political process, and the government is accountable to the people. Key features of democracy include a free press, an independent judiciary, and the protection of individual rights and freedoms. While there are many variations of democracy, the basic principles include equality, freedom, and the rule of law.
