Preparation of base map being in mind, the forest, agriculture, water, road and boundary are almost same for all but theme may be different as per requirement. Base information is to survey and need terrain information, the preparation includes land forms by separation of water, kart area, coastal area. Meanwhile preparation of focus might be on DEM (Digital Elevation Model) and water movement helps in demarcation of boundaries on map.

Age old practice of photography was taken with still camera in parallel direction, not aerially scan or snapping which really present wider prospective of any object or places in rearranging or planning skilfully in two dimensional working. Earlier aeroplane played a important role in over head condition to capture snaps but again accuracy and angle of camera limited the works because these photographs were diagonally or trigonally not matched the reality of ground.

Fundamentally toposheet represents a kind of map in which topographic features of particular area is given details on the map features in two dimensional land surfaces. It shows both horizontal and vertical portion of the terrain with a combination of contour lines, contours, symbols, labels and related representation together in one piece of paper. Toposheet portray the shapes, location of mountains, many natural and manmade features, and the toposheet combinedly uses for extracting accurate information about particular area containing land surface features.

Aerial photography is objective of getting panoramic view of earth surface to analyze the features of earth and their interrelation at particular time period which may be changed in further events. In this concerned, the observation may play a vital role in achieving the goals of photography. Undoubtedly it is widely used in social function and so on, but still awaited for scientific or research use. Drone can measure the geometry of ground surface at lower altitude with more accuracy in the form of visual feature in natural colour. flight height of drone mainly limits the large area coverage due to lower flying and drone can work perfectly at low altitude planning with good quality feature/photography.

The information of image is perfectly accepted by eyes when the image will be in convenient form. Always pictures accurately detail about information related to their position, sizes and inter-related with each other is objects. Actually images portray positional information which can be recognized as objects. Human eyes are exact example for differentiating that information from images to innate visual and mental ability.

In beginning of aerial photography, the photos were taken to evaluate existing topography, plan observation and sampling incursion. After World War II, the assessments of aerial photographic data were much more difficult, and real geological data started to be extracted. The use of stereoscopic pairs enabled geologist to explain height structural features. But, the basic use of remote sensing data were collected was in explanation. These trends of comparative photography until development took place into the satellite age when satellite imagery began popular and commercially available. The availability of various imageries in several combinations opened a option to analyze regions in much more detail. Apart from this, the multiple flying allowed a prospect to be viewed in various light during differnt seasons. The development drastically decreased the cost of regional exploration by minimizing repeated trips to a place for reassessing. This permitted data to be gathered from the tropics and arid regions that was previously difficult task in wide regional field exploration. As computer age progressed being developed and enhanced the value of data that allows imagery as digitally highlighted specific features. Ground features like differential cropping, drainage patterns, and folds/faults may be identified.

Remotely gathered data are available from a range of sources and data collection techniques is often one type of tool that is not always found within the public domain easily. This is larger due to the fact that most of the data are acquired by equipment is expensive to build and maintain. However, there are many types of basic imagery, high-quality imageries are readily available widely at subsidized costs, particularly the purpose intented.

The stiffness of starch gels from different starches at 5% concentration was shown in decreasing order of stiffness in the following table. Of the cereal starches corn starch gel was firmest followed by wheat and rice starch gels. Among the roots and tubers starches, potato yielded a ropy paste, arrowroot a soft paste while cassava starch gave viscous fluid.

Leavening agents produce carbon dioxide which helps to give characteristic structure to bread cakes and biscuits etc. In the case of cakes, leavening is produced by air entrapped in the dough due to the presence of egg in the mix. The important groups of leavening agent’s are l. baker’s yeast 2. Chemical leavening agents

1. Clean and wash the pulses, Mix the pulses with water, soak for 1 hour, 3 hours, 6hours, 9hours and overnight.
2. After soaking drain the water wash thoroughly and add fresh water keep it for boiling/cooking.
3. Study the effect of Acid and effect of Alkali on cooking time of pulses.

Procedure: weigh vegetables 20 g (for each variation) Water: add sufficiently
1. Cook the vegetable in water in a pan according to the “cooking time” variations given in the table 1 and note down the color, texture and flavor changes takes place during cooking for each variation and record the observations

Physical Properties of milk
Procedure: Collect different types of market milk samples and study the  properties of milk. Boil the milk and note down the properties given in table 1 and record the observations

Ingredients; milk fat (cream)-12%, non-fat milk solids (skim milk powder)-11%, sugar-15%, stabilizer-0.2%, emulsifier-0.2%, flavors-a pinch Basic ice cream preparation: 1. Mix the ingredients 2. Pasteurization 3. Homogenization 4. Ageing (allowing to standby 24 hours at 4.440C) 5. Freezing (the mix is frozen at 5.5560c) 6. The freezing must be quick in order to prevent formation of large crystals. The ice cream is semi solid at this temperature. 7. The ice cream is finally frozen to a hard mass at about -30C.

In order to assess the quality characteristics of eggs the book reference values were taken for comparison

(Ref: 1997-2016 American Meat Science Association)
The methods used for cooking meat can be divided into two groups:
1. Dry heat methods
2. Moist heat methods

Poultry meat-50 g for each method
Cook the poultry meat according to the methods given in the table and record the cooking effects

Takes clean, washed and edible fish-50-100 g for each method of cooking. And cook the fish according to the methods given table and record the characteristics of cooked fish.

Procedure: Measurement of smoke point of given oils: Heat the given oils in a deep frying pan till fumes come out from oil. Record the temperature when the fumes come out and noted it as a ‘smoke point’. Cool the oil by keeping oil pan at room temperature. After cooling repeat the heating of same oils 2nd and 3rd time to measure the smoke point and record the observations

Pure sugar when heated melts at about 160-1800c. at about 2100c sucrose loses water and becomes caramel.

Sensitivity-Threshold tests Sensitivity tests are conducted to assess the ability of individuals to detect different tastes, odors and feel the presence of specific factors in.

Formulation & method of bread making Baking is an exact science that requires precise measuring and accuracy. Accuracy is crucial in baking because most baked products are made from the same basic ingredients: flour, liquid, fat, sugar, salt etc. the difference between baked products are often the proportion of each ingredients in the formula. If the proportions are off, you will end up with a different product or an unacceptable product.

Drying is one of the oldest methods of preserving food. It is usually accomplished by the removal of water. Dried foods are preserved for long storage time because the available moisture is very low, so that the micro organisms cannot grow and enzyme activity is controlled. It is done by many methods. 1. Sun drying 2. Using mechanical dryers.

Selection fresh fruits/frozen stored fruits/chilled fruits/fruit pulp/sulphited fruit. Wash them to remove the dairt, dust, stems, leaves, stalks, undesirable portions.

Pickling is the process of preserving or extending the shelf life of food by either anaerobic fermentation in brine or immersion in vinegar. The pickling procedure typically affects the food’s texture and flavor. The resulting food is called a pickle, or, to prevent ambiguity, prefaced with pickled. Foods that are pickled include vegetables, fruits, meats, fish, dairy and eggs.

Yogurt is a fermented milk product that contains the characteristic bacterial cultures such as Lactobacillus bulgaricus and Streptococcus thermophilus. All yogurts must contain at least 8.25% solids not fat.

The RTS beverage was prepared by using freshly prepared carrot juice, sour orange juice, water and sugar as per FPO specification.

Education: Education is the production of desirable changes in the behaviour of the people. It is the production of desirable changes in human behaviour in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them.

Behaviour: Includes three components viz., knowledge, attitude and skill

Knowledge (Cognitive): It includes facts, concepts, principles and relationship.

Attitude (Affective): An attitude can be loosely defined as a feeling towards some object, person and situation or idea.

Programme Development

Programme development is an on-going dynamic process that extension professionals intuitively follow as they plan, implement and evaluate their educational programmes. The process is not confined to a five-year planning cycle. It is applied on a small scale as an individual workshop is being developed, on a larger scale as a series of programmes are being developed around a single priority and on an even larger scale at district level and state level wide team sets priorities and defines a plan of action for a five-year period. The basic principles remain the same, only the scope is different. The gap between the situation and objective is the area of needs. This area becomes well-defined after the situations and the objectives are determined by the leaders, extension professionals and specialists.

Introduction

About 65 percent population of the country is living in the economically undeveloped area. Therefore, many evils such as illiteracy, superstitions, unhealthy practices etc. took roots in our country. After Second World War or after independence, it was thought to settle all these problems properly and so, many development programmes were reinvigorated. It is wrong to declare that there was nothing done during slavery period. However, those works, which were executed at that time, were very few in number according to the needs. Looking at a vast country like India, during British rule some selected social workers had started some programmes of rural development. The evolution of extension programme is described in two stages.

First Line Extension system

Realizing the scope and importance of integrated working of interrelationship between research, education and extension functions, the ICAR established a section of Extension Education at its headquarters in 1971, which was later on strengthen and renamed as division of agriculture extension. It was intended to enforces this functional relationship down the line in the research institute, agricultural universities and allied institutions.

Introduction of Training and Visit System

This Training and Visit system was developed by World Bank Expert Daniel Benor. Initially (13) Major states in India adopted Training and Visit system but later on most of the states are practicing this system since 1984 onwards.

Innovations in Field Extension

Of late, a lot of emphasis is being given on innovative extension approaches at the field level, in order to ensure an effective implementation of the Transfer of Technology (ToT) process. Many such new initiatives have been undertaken in India, the details of which are as under.

Farmer Field Schools - ANew Participatory Approach

Plans need not be made for nuts and bolts, but are essential to prevent future bottlenecks. If enough cushions are provided for the future, the economy will grow smoother and faster. The importance of plan is that when you design it before you implement it; you have a better chance of eliminating design flaws from the beginning. If you start out coding and later on figure out you have a design flaw, it is extremely painful to go back and re-implement everything. Certain software engineering experts have estimated that it can cost up to 10x more (time and money) to fix a design problem in the later stages of software development than in the early stages.

Rural development has always been an important issue in all discussions pertaining to economic development, especially of developing countries, throughout the world. In the developing countries and some formerly communist societies, rural mass comprise a substantial majority of the population. Over 3.5 billion people live in the Asia and Pacific region and some 63% of them in rural areas. Although millions of rural people have escaped poverty as a result of rural development in many Asian countries, a large majority of rural people continue to suffer from persistent poverty. 

The word ‘Democracy’ is derived from the Greek roots ‘demos’ meaning the people and ‘kratos’ meaning authority i.e. in democracy, all authority originates from the people. Decentralisation means distribution of functions and powers from a central authority to regional and local authorities. Democratic Decentralisation in the present context means that the Government which has derived its authority from the people, redistributes it to some extent to the people, for decision and action at the local level. This is popularly known as PANCHAYATI RAJ in India. It was thought that Panchayati Raj would emerge as a system of democratic local self- Government, discharging developmental municipal and ultimately, regulatory functions.

The four main projects of the transfer of technology projects of the ICAR.

The projects are:

1. All India Coordinated Project on National Demonstrations
2. Operational Research Project
3. Krishi Vigyan Kendra (Agricultural Science Centre)
4. Lab to Land Programme.

Community

1. A community is a group of people, who live in a geographical area and have an interest in each other for the purpose of making a living. It is a form of social organization existing between the family and state.
2. The people with common interests living in a particular area
3. An interacting population of various kinds of individuals (as species) in a common location
4. A group of people with a common characteristic or interest living together within a larger society

High Yielding Variety Programme (HYVP)

High Yielding Variety Programme (HYVP) was launched in 1966, which helped the country in attaining self-sufficiency in food. The technological development did not remain confined to the introduction of high yielding crop varieties alone. These were combined with the application of high analysis and balanced fertilizer, irrigation, plant protection, improved implements etc. which made a ‘Green Revolution’possible in the country.

National Agriculture Technology Project (NATP)

This project was launched by the ICAR on June 30, 1998, with the support of the World Bank to strengthen and complement the existing resources and to argument the output National Agricultural Research System (NARS).

Objectives

The major objective of this component is:

National Rural Employment Programme (NREP)

The NREP was launched in October, 1980 and became a regular Plan programme from April, 1981. The programme was expected to generate additional gainful employment in the rural areas, to the extent of 300-400 million mandays per annum, create durable community assets, and improve nutritional status and living standards of the poor.

An outlay of Rs. 1620 crores was provided under this Programme, out of which the outlay from 1980-81 onwards (Rs. 1280 crores) was to be shared equally between the Centre and the States.

Indira Awaas Yojana (IAY)

Indira Awaas Yojana, which used to be a component of Jawahar Rozgar Yojana became an independent Scheme from 1997-1998 onwards. Its objective is construction of free houses to members of the Scheduled Castes/ Scheduled Tribes, Freed Bonded Labourers in Rural areas and also to non SC/ST rural poor living below poverty line. The beneficiaries are selected from the Below Poverty Line (BPL) list approved by the Grama Sabha. Atleast 60% of the total IAY allocation during a financial year should be utilized for construction/ upgradation of dwelling units for SC/ST BPL rural households. A maximum 40% of allocation is for non- SC/ST BPL rural households. 3% of the above categories should be allocated for physically and mentally challenged persons. 

Sampoorna Grameen Rozgar Yojana (SGRY)

This scheme has been merged with NREGS since February 2006 so only most important points are given below.

1. The Sampoorna Grameen Rozgar Yojana (SGRY) was launched on 25 September, 2001 by merging the on-going schemes of EAS (Employment Assurance Scheme) and the JGSY (Jawahar Gram Samridhi Yojna)
2. Objective was to providing additional wage employment and food security, alongside creation of durable community assets in rural areas.
3. The annual outlay was Rs.10, 000 crore which included 50 lakh tones on food grains.
4. The cash component shared between the Centre and the States in the ratio of 75:25.

Community Development concepts

The United Nations defines community development as “a process where community members come together to take collective action and generate solutions to common problems. It is a broad term given to the practices of civic leaders, activists, involved citizens and professionals to improve various aspects of communities, typically aiming to build stronger and more resilient local communities.

Community development is a process where community members come together to take collective action and generate solutions to common problems. Community wellbeing (economic, social, environmental and cultural) often evolves from this type of collective action being taken at a grassroots level.

Leader

Leader is aperson who influencing people so that they will strive willingly towards the achievement of group goals.

A leader is one who inspires, motivates and leads people to accomplish organizational goals.

Leaders’ styles encompass how they relate to others within and outside the organization, how they view themselves and their position, and to a large extent whether or not they are successful as leaders.

Meaning of Administration

The Management of public affairs of a government or institution is called administration. In extension education knowledge of administration is very important which can be developed by administrators. This knowledge will make the administrators aware of some of the unanticipated consequences of their decision. Secondly proper administration makes the administrator to his/her skill. Knowledge for solving problems of organization for which they are members.

Definition of Monitoring and Evaluation

Systematic recording of observations, information, gathering, analysis, documentation, reflection, action and re-planning is called monitoring.

It provides programme/projects managers and key stakeholders with regular feedback and early indications of progress or lack of in the achievement of intended results.

Privatization of Agricultural Extension

Process of funding and delivering the extension services by private individual or organization is called Private Extension. Privatization is the act of reducing the role of Government or increasing the role of private sector in an activity or in the ownership of assets. Privatization is the incidence or process of transferring ownership of business from the public sector (Government) to the private sector (business). Private Extension is solely the act of private individuals or organizations where the decision of privatization solely rests with Government implemented in liaison with private extension service provider.

e-Extension

E-extension can be defined simply as the use of electronic technologies (especially ICT) to enhance face-to-face and paper-based transactions. These technologies can be as simple as teleconferences or as complex as wikis and blogs.

Cyber extension (also known as e-extension) may be defined as extension over the cyber space, the imaginary space created by the interconnected telecommunication and computer networks.

Agri portals

• Website that serves as a gateway or a main entry point (‘cyber door’) on the internet to a specific field of interest or an industry.
• A portal provides at least four essential services.
  1. Search engine(s).
  2. Email.
  3. Links to other related sites and.
  4. Personalized content.
  5. It may also provide other facilities such as chat, members list, free downloads, etc.

History of Expert System

Expert systems were introduced by researchers in the Stanford Heuristic Programming Project, including the “father of expert systems” Edward Feigenbaum, with the Dendral and Mycin systems. Principal contributors to the technology were Bruce Buchanan, Edward Shortliffe, Randall Davis, Williamvan Melle, Carli Scott, and others at Stanford. Expert systems were among the first truly successful forms of AI software. In the 1980s, expert systems proliferated as they were recognized as a practical tool for solving real- world problems. Universities offered expert system courses and two thirds of the Fortune 1000 companies applied the technology in daily business activities.
