Rural Development : Concept and Meaning

Mahatma Gandhi said, “India lives in its villages. If the village perishes, India will perish too”. This saying about the social, economic and political development of rural areas justifies that India is predominantly an agrarian country with more than 70 percent of its population living in more than five lakh villages. Agriculture is the predominant livelihood occupation and the rural population largely consists of small and marginal farmers, agricultural labourers, artisans and scheduled castes and scheduled tribes. A large part of this rural population is still living below the poverty line and is the focus of rural development programmes. Rural Development is not a new concept for India rather it is a very basic principle of our culture. The famous epics like Ramayana and Mahabharata teach us the dignity of humanity and benevolence and justice to people. In ancient days, our villages were self-sufficient and requiring very little assistance from outsiders. However, during British rule, the rural economy was destroyed and the rural mass was made dependent on goods and services provided by outsiders. There was no rural development policy as such to make the people self-reliant. Some of the rural development activities were taken up by the British Government in India during the Great Bengal Famine. These attempts were of very limited scale without having legal sanctions behind the move.

Data Collection and Report Writing

Many a times you may be asked questions like what is the average milk production of deshi cows of your area? What is the average lactation period of CB cows of your area? or maybe what is the impact of AI programme in your area? etc., by your higher officers. How to answer all these questions? All these questions may be answered scientifically if you possess elementary knowledge on statistics. We have to frame a research design and to collect data to answer these questions.

What is Data ?

Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things. Example: 5, Ram, Kilogram, Good, Male, etc. Independently they do not produce any meaning.

These are special types of information, generally obtained through observation, surveys, enquiries or are generated as a result of human activities.

Once you have decided what to study and how to study, you are faced with the task of systematically collecting reliable and valid evidence upon which you can base your findings. Data (singular datum) are facts which are observed and measurable phenomena. The purpose of gathering and summarizing data is to transform them into information. The data collected in the research study may be quantitative or qualitative in nature. Quantitative data can be counted and can be computed. Such as age of a boy, marks scored by a student, distance, etc. Quantitative data are easier for analysis. We also collect qualitative data like sex of a person as Male or Female or Transgender. The qualitative characteristics can be counted, but as such cannot be computed. For example, we may get “Yes’ or “No” to a question to farmers about vaccination of his animals. For this “Yes” or “No” , we may assign 0 to “Yes” and 1 to “No” in an artificial or nominal way to categorise these qualitative data, and go for computation. So, quantitative data are expressed in the form of numerals and are amenable to statistical analysis readily. Whereas, qualitative data are descriptive in nature and can be statistically analysed only after processing and after having them classified into some appropriate categories. Data is required to make a decision in any business situation. The researcher is faced with one of the most difficult problems of obtaining suitable, accurate and adequate data. Utmost care must be exercised while collecting data because the quality of the research results depends upon the reliability of the data. There are basically two sources from which we obtain data for our research works. They are known as primary data and secondary data.

Extension Programme: Planning and Evaluation

The first step to promote any extension programme is to prepare useful programme based on community need. Extension Programme planning is a blueprint or plan to an extension worker for effective execution. It is a procedure of working with people in an effort to identify and recognise the unsatisfactory situations or problems and to determine the possible solutions. To understand the extension programme planning process, certain basic concepts of an extension programme, planning and extension planning need to be understood.

Programme

The word ‘programme’ has several distinct meanings in the dictionary. It means a proclamation, a prospectus, a list of events, a plan of procedure, a course of action prepared or announced beforehand, a logical sequence of operations to be performed in solving a problem. This is a written statement which describes the extension activities proposed, the problems they address, the premises on which they are based, the objectives they seek to attain, the actions and the resources they require.

Diffusion and Adoption of Livestock Innovations

One of the important functions of livestock extension worker is communication. This communication is not mearly informing the livestock owners about the improved technologies and practices, but to ensure the application of technologies for their benefits. Livestock extension worker’s efficency are always judged and measured (a) by the speed or quickness with which the gap between what is known and what is done by the livestock farmers is bridged, (b) by the number of new practices adopted; and (c) also by the number of livestock farmers and communities that adopt the new practices. While discharging the technology dissemination function, livestock extension worker often faces with some of the difficult questions:

Rural Sociology

Significant proportion of Indian population lives in village and derives their livelihood from villages. India is a land of agriculture and its customs, traditions, social structure, etc. are unique in the world. Understanding of rural society is must for successful implementation of developmental programmes. The understanding of rural people requires study of rural sociology. Rural sociology, as indicated by its name, studies rural society, rural social structures and institutions. The rural society is primarily depending on agriculture and hence rural sociology also concerns itself on the peasant society. There is a stark difference between the social structure, processes, social dynamics and social control in rural society and urban society. Thus, rural sociology has been specially designed to study the rural phenomena and it is a systematic study of the varied aspects of the rural society. It is the study of the rural social networks and how they operate for the smooth functioning of the society. The rural society is generally rooted in the villages, and rural sociology studies the facets of the villages, the way it functions, the various problems it faces and the how it tackles to face the imminent challenges. Rural sociology offers viable solutions and ways of mitigating the problems that hound over the villages.

Participation means the involvement of the stakeholders in all the activities. In a true sense of participation, the farmers are involved in identifying the problems they face, prioritising the problems, determining ways to overcome them, designing realistic plans by themselves or with others to achieve the goals, and carrying them out. Participation puts emphasis on people’s involvement in decision-making processes, implementation of programmes, sharing of benefits of development programmes and involvement to evaluate such programmes. Community participation is an active process by which beneficiary or client groups influence the direction and execution of a development project with a view to enhancing their well-being in terms of income, personal growth, self-reliance, or other values they cherish. Community participation concerns the engagement of individuals and communities in decisions about things that affect their lives. Sometimes you have observed that some people do not want to be involved in decision making process and remain aloof, but it is our responsibility to create a situation so that everyone should have the opportunity to associate with the programme. We should not force people to participate in the project/programme which they perceive that it will affect their livelihood. In that case, we have to create awareness among the people regarding the beneficial effects of the programme. Solutions devised and fulfilled by the people and community in need are far more likely to prove successful than those imposed from outside.

Role of Male and Female Extension Workers

Extension Workers include all persons working in the field for improving the qulaity of life of people. In our field, Gomitras, Livestock Inspector, VAS, BVO, etc are all extension workers because some way or other they are involved in promotion of livestock activites in the field. The role of extension worker working with rural people is to bring necessary change inindividual and collective behaviour and motivating them. The role of male and female extension worker is not very distinct. However, in some backward communities, the role of the female extension worker to motivate women, is found to be very encouraging. Here, we will discuss the important roles of both male and female Extension workers.

An extension worker should arouse farmers to recognize and take interest in their problems, to overcome these problems, to teach them how to do so, to persuade them to act on his teaching, so that they ultimately achieve a sense of satisfaction and pride in their achievements.

Communication and Extension

We spent most of the time in a day by communicating with others. It is impractical to think of a life in which we don’t communicate. Communication is a process not only limited to human beings. All creatures of earth communicate with each other for their better existence. In communication, we exchange our ideas, information, feelings, opinions about an issue, emotions, etc. with others throughout our life. It indicates that the communication is inseparable from the existence of life. A hypothetical example on the various kinds of communications that a Veterinary doctor might be using on a normal day is presented below for easy understanding.

A Veterinary doctor goes to office and put his signature in the attendance register (written communication) and greets his staffs (communication through gesture). Then he attends the patients and discuss with the owner (verbal communication). He writes prescription for the ailing animals (written communication). After office works, he may visit and discuss with the villagers about a vaccination programme (group communication) and inform the villagers about the date and time of vaccination. He may sensitize the people about the importance of vaccination through television, radio, newspaper, etc. (mass communication) and develop leaflets/folder/bulletins on different issues for distribution. This brief example suggests that the communication is an inevitable part of our daily life. It may be like that we may not survive without communication.

EXTENSION TOOLS /AIDS

Audio-visual aids, audio-visual media, audio-visual material, communication technology, educational or instructional media, extension teaching aids, extension tools, extension aids, etc, - all these terms broadly speaking, mean the same thing. The use of the terms like educational technology or instructional technology instead of extension tools/aids in the recent time is primarily due to the dynamic expansion of programmed learning, computer assisted instruction and education television. In this discussion, the term audio-visual aid is used most frequently which is almost same as extension aids.

Extension Teaching Method

The function of extension education is to bring about desirable changes in the behaviour of a human being. The changes in human being are produced by increasing his/her knowledge level, improving skill and changing attitude. For all these to happen, an individual has to be taught, trained and communicated. So, the extension education emphasizes the process of communication, and if you examine, you will find that the extension education is broadly a teaching-learning process in which a learning situation is created by an extension worker/ teacher by which an individual attempt to change his/her behaviour. The learning situation created in extension education process is a condition or environment in which the elements like teacher, learner, subject matter, physical facilities and teaching methods and aids for promoting learning are present in a dynamic relationship with one another. The quality of learning depends upon the conditions created by the teacher for learners to learn. However, the learner is the key element in the teaching and learning process. His willingness and desire for change are very important. The third element; subject matter is the content of the message that the extension worker wants to transfer to the client. Transfer of the subject matter will be easy and effective if it is valid, correct, based on facts, applicable to practical life situation and need based. Effective teaching-learning process is also affected if physical facilities like place, light, ventilation, seating arrangements, etc., are not properly provided to both teachers as well as to the learners. Besides all these, the transfer of subject matters to the learners requires the help of suitable teaching methods, aids and media. Proper selection and handling of methods and aids facilitate in creating the desirable learning situation. The teaching methods and aids should be simple, easy to handle, suitable to subject matter, readily available, suited to the environment and needs of the learners.

Extension Teaching

It is now evident that the extension is an educational process which attempts to produce desirable changes in the human behaviour. This educational process is nothing but teaching-learning process and this is explained by Leagans (1961) as follows:

Teaching is the process of arranging situations that stimulate and guide the learning activity towards the goals that specify the desired changes in the behaviour of people. Teaching consists of providing situations in which the things to be learnt are brought to the attention of the learners, their interest is developed, desire aroused, conviction created, action promoted and satisfaction ensured.

Learning is the process by which an individual, through his own activity, changes his behaviour.

Process means a course of procedures, something that occurs in a series of actions or events conducting to the desired end.

The term extension is more recent in origin, and was first recorded in Britain in the 1840s in the context of ‘university extension’ or ‘extension of the university’. James Stuart, Fellow of Trinity College, Cambridge, who gave several lecturers to women’s associations and working man’s clubs in the north of England during 1867-68, is considered as father of extension. The term extension was derived from the practice of British universities of having one educational programme within the premises of the university and another away from the university buildings. The programme conducted outside the university was described as “extension education”. The expression connoted an extension of knowledge from the university to places and people far beyond. But, the term ‘Extension Education’ was formally used for the first time in 1873 by Cambridge University of England to describe system dedicated to the dissemination of knowledge to rural people where they lived and worked. Within a short time, the idea had spread to other parts of Britain, Europe and North America. Extension work is an out of school system of education in which adults and young people learn by doing. It is a partnership between the government, the land-grant institutions, and the people, which provides services and education designed to meet the needs of the people (Kelsey and Hearne, 1966). The meaning of the term ‘extension’ has changed over time, and has different meanings to different countries. The term ‘’Agricultural Extension” was adopted in 1914 when the United States Federal Smith-Lever Act of 1914 formalized a nationwide cooperative federal-state-county programme and gave operational responsibility for this to the land grant colleges and Universities. In the beginning, agricultural extension was concerned primarily with the improvement of agriculture, using conventional teaching methods. As time went on, home economics, youth programmes and rural community resource development were included. Agricultural extension spread to tropical Africa, the Caribbean, Asia and Latin America following the involvement of the United States of America (USA) in bilateral AID programmes after the Second World War.

1. DUS TEST

A variety shall express distinct character(s) for verification, uniformity within population and stability for expression of such characters over the year and at different locations, then only its genetic purity is confirmed.

1.1. Requirements

Authentic seeds of existing varieties, pure seeds of variety under tests, list of characters to be examined and their expression.

This test is conducted in the most optimum conditions of soil and climate and the crop is exposed to the best agronomic management conditions to ensure full expression of the characters.

1.2. Distinctness

The variety under test is compared with the existing varieties (having similar plant height, growth habit, days to flowering, days to maturity and reaction to diseases) for qualitative morphological characters at seed, seedling and plant levels. Biochemical differences may also be considered. To establish the distinctness, the test is performed for 2 years for self pollinated crops.

1. PPV & FR ACT

With the signing of TRIPs agreement of the World Trade Organization (WTO), India has agreed to provide protection to plant varieties. The Government of India, therefore, enacted “ The Protection of Plant Varieties and Farmers Rights Act (PPV&FR Act)” in 2001 and the Regulations for implementing the Act were formulated in 2003.

The Ministry of Agriculture, Government of India, has been identified as the nodal agency for implementing the PPV& FR Act through an Authority known as “The Protection of Plant Varieties and Farmer Rights Authority”. The Authority came into force in November, 2005.

PPV & FR act has 11 chapters, 4 schedules and 97 sections.

1. DEFINITION

Seed marketing is the one of the most vital components of seed technology. On it depends the size and scope of the seed industry. Broadly it includes such activities as production, processing, storage, quality control and marketing of seeds.

Seed marketing refers to the actual acquisition and selling of packed seeds, intermediate storage, delivery and sales promotional activities.

1. SEED INDUSTRY BEFORE INDEPENDENCE

The Royal Commission on Agriculture (RCA) constituted in 1925 suggested the following for seed improvement

There should be a separate organization within agriculture departments to deal with seed distribution and seed testing.

The seed distribution enterprise should be self-sustaining.

Seed distribution should be organized through co-operatives, other associations, seed merchants (whenever they are available), through seed agents, as well as through agricultural department staff and any other agency which could be considered suitable.

Seed merchants of proven enterprise should be given every encouragement.

1. NEMATODES

Nematodes, also called eel-worms, are wormlike in appearance, but quite distinct taxonomically from true worms. They live freely in fresh or salt water or in soil. They are saprozoic and also parasitize animals (including man) and plants. Many species of nemotdes parasitize higher plants and cause disease symptoms. Plant parasitic nematodes are small (invisible to the naked eye), long, tubular, round in the cross section, unsegmented and smooth invertebrates. They inhibit different parts of plants, namely, roots, stem, flower buds and seeds. Depending on the host-parasite relationship, plant parasitic nematodes may be sedentary or migratory and ectoparasitic and/or endoparasitic in their feeding habits.

1.1. Nematodes

Seed-borne nematodes may be internal or may occur as seed infestation. Several saprozoic soil nematodes occur in beds of soil mixed with seed. Seed infestation by nematodes does not produce any specific symptoms on seed, but in those that occur as endoparasites, the floral structure may be modified into a seed gall (Anguina spp.) may produce symptoms such as discoloration of testa in groundnut (Ditylenchus destructor) or may be symptomless as in paddy kernels infected by Aphelenchoides besseyi. Neergaard (1979) listed five genera - Anguina, Aphelenchoides, Ditylenchus, Heterodora and Rhadinaphelenchus - that are seed-transmitted. Heterodora and Rhadinaphelenchus occur as endoparasites in roots, stems, and leaves. The latter also affects the growing apex, inflorescence and husks of dropped nuts.

Weight loss: For grains or grain legumes in the tropics, a weight loss in the range of 10-30 per cent might be expected over a full storage season.

Loss in quality/market value: Infested seed is contaminated with insect debris and has increased dust content. Seeds are holed and often discoloured, which fetch low price.

Promotion of mould development: In humid conditions, without adequate ventilation, mould development and caking can spread rapidly, causing severe losses.

Reduced germination in seed material: Damage to the embryo of the seed will usually prevent germination. Some storage pests prefer to attack the embryo.

1. INTRODUCTION

Seed health refers to the health status of a seed. Sowing healthy seeds of high quality is our concern to improve crop yields, thus increasing food production. It has a great concern to farmers and seed producing agencies where the disease is high and average yields are low and where more food is needed to feed the ever-increasing population. So, it is important to test the seeds for disease organism before they are sown in the field and to avoid harmful organisms traveling from infected to non-infected areas within a country or across international boundaries.

1. SEED PATHOLOGY

The area of science that studies the relationship between pathogens and seeds is seed pathology.

2. TYPES OF PATHOGEN

Diseases of plants are caused primarily by three types of pathogens: bacteria, fungi, and viruses. Despite that fungi comprise the largest group of pathogens, the bulk of seed-specific diseases are caused by bacteria or viruses. This is due to the fact that bacteria and viruses are more adopt at entering and then travelling through the veins of the plant, a phenomenon known as ‘systemic infection,’ and from the vascular system may make their way into the developing embryos of seeds.

Fungi, in contrast, tend to be restricted to the outer layers of the plant, where they initiate infection by means of air-borne spores and then proceed to spread by attacking nearby cells of the outer layers. Fungi are much less likely to enter the vascular system of the plant, and thus infect seed mostly when they either ‘crawl’ all the way to seed on the outside of the plant, or else send out spores that land on the seed. In either case, the fungal spores are on the outside of the seed, in the layers of the seed coat, spores on the seed coat are more prone to either dry up and die, or else to get sloughed off with the seed coat during seed germination, thereby failing to cause disease on the next generation of plants.

1. GERMPLASM

A germplasm is a collection of genetic resources for an organism. For plants, the germplasm may be stored as a seed collection or for trees, in a nursery.

1.1. Conservation methods

1.1.1. In situ conservation

The conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. Conserving the areas where populations of species exist naturally is an underlying condition for the conservation of biodiversity. That’s why protected areas form a central element of any national strategy to conserve biodiversity.

1. SEED TREATMENT

It refers to the application of pesticides (fungicides, insecticides or a combination of both) to seeds before sowing and/or storage in order to protect the seeds and young seedlings from soil borne pathogens and/or storage pathogens and insects. Seeds are thoroughly mixed with required quantities of chemicals namely bavistin (carbendezim) @ 2-4 g/kg of seeds.

1. DEFINITION

Seed deterioration is defined as deteriorative changes occurring with time that increase the seed’s vulnerability to external challenges and decrease the ability of the seed to survive

1. SEED STORAGE

Is the maintenance of high seed germination and vigour from harvest until planting.

1.1. Importance of seed storage

Seed storage is important to get adequate plant stands in addition to healthy and vigorous plants.

1. SEED TESTING

The science of evaluating the planting value of seed has been developed to achieve the following objectives for minimizing the risks of planting low quality seeds.

To determine the seed quality and its suitability for planting

To identify seed quality problems and their probable cause.

To determine the need for drying and processing, if any.

To determine if seed meets established quality standards for labeling.

To establish quality and provide a basis for price and consumer discrimination among lots in the market.

Founded in 1924, with the aim to develop and publish standard procedures in the field of seed testing, with member laboratories in over 70 countries world wide. ISTA membership is truly a global network. ISTA secretariat is located at Zurich, Switzerland.

1. VISION AND MISSION

ISTA members work together to achieve their vision of ‘Uniformity in seed quality evaluation worldwide’. The association produces Internationally agreed rules for seed sampling and testing, accredits laboratories, promotes research, provides International seed analysis certificates and training and disseminates knowledge in Seed Science and Technology. This facilitates seed trading Nationally and Internationally and also contributes to food security.

1. INTRODUCTION

For maintenance of genetic purity in the field with the seed crop and to test verify the standards in certification programme, the studies on varietal characterization and identification have attracted the attention of breeders, breeder’s right protection institutions, farmers, the seed industry, certification agencies, and seed testing laboratories with a view to assure the quality of seed marketed to the consumers.
