Botanical Name: Borassus flabellifer L.

Family: Arecaceae

Chromosome No: 36

Place of Origin: Tropical region of Africa, Asia and New Guinea

5.1 Introduction

Palmyrah is a monocotyledon and perennial crop. The word “Borassus” was derived from a Greek word and it means the leathery covering of the fruit and “flabellifer”, means fan-bearer. The distinguishing characters of palm in this genus are their palmate, fanlike leaves and dioecious character, i.e., male and female flowers are borne on separate trees (sex ratio 1:1), allotetraploid (X= 8 or 9, n = 18), the male tree has a heteromorphic XY pair of chromosomes while the female has an XX pair (Sankaralingam et al., 1999). Next to coconut, palmyrah is the most abundant palm found in the world. Palmyrah thrives in arid conditions and is grown extensively in Tamil Nadu. Palakkad district of Kerala is popularly known as land of palmyra trees. Palmyra trees are known as the icon of this district and have a vast cultural, heritage and literary association.

Importance

It is one of the most valuable primary products in world trade, in many years second in value only to oil as a source of foreign exchange to producing countries. Its cultivation, processing, trading, transportation and marketing provide employment for hundreds of millions of people worldwide. Coffee is crucial to the economies and politics of many developing countries; for many of the world’s Least Developed Countries, exports of coffee account for more than 50 percent of their foreign exchange earnings. Coffee is a traded commodity on major futures and commodity exchanges, most importantly in London and New York.

16.1 INTRODUCTION

Portulaca is an annual potherb, but may be perennial in the tropics. In many parts of the world, it is still regarded as a weed with nutritional potential. Its young stems and leaves are succulent and edible with a slightly acidic and salty taste. Stems are glabrous, f leshy, purplish-red to green, arising from a taproot, often prostrate, forming mats. It is described as a power food of the future because of its high nutritive and antioxidant properties. It contains more omega-3 fatty acids (300 to 400 mg/100 g of fresh leaves) than any other leafy vegetable plant. Succulent leaves and stem also contain dietary minerals, such as calcium, phosphorus, iron and potassium, as well as vitamins A, C and E and some amount of vitamin B and carotenoids. It has been recommended as a cholesterol lowering agent and as a therapy for arteriosclerosis. Generally, roots and leaves contain more iron and manganese than stems. Due to oxalic acid and nitrate content, excessive consumption of purslane is not recommended. The cultivated form of Purslane, i.e., Portulaca oleracea (garden or green purslane) and Portulaca sativa (yellow leaves, less hardy than the green purslane but possessing the same qualities), is hexaploid. Purslane is a succulent and well-branched herb, leaves are spirally arranged, f lowers are yellow, stamens 7-10, style with arms, fruit ovoid, capsule, seeds numerous, tiny and black in colour.

19.1 INTRODUCTION

Roselle is a perennial shrub but grown as an annual. In the seventeenth century, the vegetable types were introduced to India and the United States of America. It is locally known as Mesta or Meshta in the Indian subcontinent. It is one of the important fibre crops, which stands next to jute in production. In India, mesta is grown in larger parts covering areas from Karnataka to Tripura including Maharashtra, Andhra Pradesh, West Bengal, Bihar, Odisha and Meghalaya. However, Andhra Pradesh has maximum area under mesta in the country. In many tropical regions, it is a popular vegetable, which is cultivated for its leaves, stems, seeds and calyces. Tender young leaves are eaten as a vegetable and the red calyces surrounding the fruit can be used to prepare non-alcoholic beverages and as colouring reagent for jelly, jam, and beverages. The stem is utilised for extraction of fibre. The plant stalks are used in making paper pulp, structural boards, as a blend for wood pulp and thatching huts. The leaves are a source of mucilage used in pharmaceuticals and cosmetics. Culinary cultivars are many branched, bushy and generally 1-2 m tall.

19.2 CHOICE OF CULTIVARS

Roselle is cultivated as a vegetable as well as fibre crop. In the beginning the tender leaves, stems and calyces are consumed. In the later stage it is used for fibre. The details of cultivars developed by different institutes and State Agricultural Universities for various uses are given below

Common Name: Rubber tree, Rubber plant, Para rubber tree

11.1 Introduction

Rubber is a fast-growing tropical tree and mainly grown for the production of latex. In 1495, Columbus was the first person to report about latex. The latex was used for rub out pencil marks and this gave the product name as rubber. The latex is used for production of various rubber products. The most important application of latex rubber was initially accomplished in the 1880s when the rubber was used for making motor cars tyres. When rubber is heated with sulphur, it retains the physical properties.

The solanaceous group of vegetables (tomato, eggplant, chili and bell peppers) generally take up large amounts of nutrients. The amount of nutrients they take up depends on the quantity of fruit and dry matter they produce, which in turn is influenced by a number of genetic and environmental variables. Tomato (Solanum lycopersicum L.) known as Tamatar in Hindi is one of the most popular and widely grown vegetables in the world ranking second in importance to potato in many countries. Tomato is widely grown in almost all parts of India and is adapted to wide range of soil and climate conditions. Tomato is consumed either as raw or cooked and is also very important crop for processing in the form of soups, juice, ketchup, puree, paste and powder. Tomato adds variety of colours and flavour to food.

Tomato is very well known for its nutritive value. Attractive red colour is due to lycopene pigment, pink and yellow colours are due to presence of anthocyanin and carotene pigments. Tomato is rich source of ascorbic acid, which varies from 15-31 mg per 100 g of fresh weight. Tomato also provides minerals like calcium, iron, magnesium, phosphorus and sodium. Tomato is also rich in medicinal value. The pulp and juice is digestible, promoter of gastric secretion and blood purifier. It is also considered to be intestinal antiseptic. It is one of the richest vegetables, which keeps our stomach and intestine in good condition.

18.1 INTRODUCTION

Sorrel is a perennial herb, which is found in grassland habitats throughout Europe from the northern Mediterranean coast to the north of Scandinavia and in parts of Central Asia. It is of two types such as Garden sorrel that is a native of Europe and south western Asia and French sorrel that is originated in the mountains of southern France and the southern and central regions of Europe and south-west Asia. The name sorrel is derived from the Germanic word, Sur and the old French word Surele, both meaning sour. It is primarily used as a culinary herb for its leaves, which are used in salads too. The leaf of this plant resembles that of spinach and have a lemony lettuce flavour and the plant is well known for strong acidity in Europe and the United States. Sorrel is a rich source of potassium, iron and vitamins A, B₁ and C. The flavour of sorrel leaves is mainly due to oxalic acid, which is harmless when consumed in small amount. Owing to high level of vitamin C content, it was rightly believed to protect against scurvy disease. It is a dioecious plant, that bears unisexual flowers, as the male and female flowers appear on different plants. When the plant flowers, they look very attractive and are often used as an ornamental plant.

18.2 CHOICE OF CULTIVARS

In India, it is not a common leafy vegetable and is grown on a limited scale, mostly in kitchen gardens. Even in Europe and other countries, different local strains are grown for both home gardening and commercial cultivation. Profusion is a cultivar, which mutated naturally in France and produces only leaves without forming seed, and hence, the plant always has fresh and ready to pick leaves.

Ginger is a perennial herbaceous monocotyledon, usually grown as annual, and is known to human as spice as well as medicinal crop. The word Zingiber is thought to come from the Sanskrit word singabera meaning ‘shaped like a horn’. It probably got its name because the rhizomes look like deer’s antlers. It first appeared in the writings of Confucius in the 5^th century B.C.

The economic part is the underground rhizomes, which is pungent and aromatic. It is valued for its medicinal properties and is useful against gastritis, dyspepsia, cold and cough. It is widely used in food, beverages, confectionery, etc. Baby ginger or young ginger results from early harvesting and is a gourmet quality product with a tender, low-fiber texture and is mostly used for pickling. Rhizome contains proteins, fibre, starch, essential oil, Zingiberol, Glutamic acid, Aspartic acid, Glucose, Fructose, and Sucrose. Most ginger varieties have about 3-6% crude fibre, 1.5-3.0% volatile oil and 4-10% oleoresin. The major pungent principle in ginger oleoresin is gingerol. Among the gingerols 6-gingerol, 8gingerol and 10-gingerol are very important in contributing the pungency. Gingerol (Hydroxy methoxy phenyl decanone) on storage gets converted to another compound called shogaol. The age of ginger oleoresin can be assessed based on the shogaol content. Chemically, gingerol is a relative of capsaicin, the compound that gives chilli its spiciness. Cooking ginger transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.

Botanical Name: Camellia sinensis L.

Family: Theaceae

Chromosome No: 30

Place of Origin: China

Common Name: Tea

9.1 Introduction

Tea (Camellia sinensis L.) of family Camelliaceae or Theaceae is the oldest and second most widely consumed beverage in the world following water. Tea is an evergreen plant that mainly grows in tropical and subtropical climates. India is world’s 2nd largest tea producer after China with production of 1.25 million tonnes in 2020. In India it is grown in an area of 6 lakh hectares, contributing one fourth of world total tea production annually. Interestingly, India is also the world’s largest consumer of the beverage and using nearly 30 percent of the world’s tea output. India stands third in terms of tea export after Kenya (including neighbouring African countries) and China. The total tea export was US$ 501.16 million in April 2020 to November 2020 and for November 2020 it was US$ 71.61 million.

3.1 INTRODUCTION

Tomato is one of the most versatile vegetable with wide usage not only in Indian culinary but also in world cuisines. Despite botanically being a fruit, it is generally eaten and prepared like a vegetable. Tomato is producing a very good source of income to small and marginal farmers and provides nutrition to the growing population. Sometimes, it is called poor man’s orange in India and Love of Apple in England. Tomato is one of the most important “protective foods” because of its special nutritive value. The100 g of edible portion of tomato contains 94.1 g of water,2.5 g of total sugar, 1.0 g of protein, 0.3 g of fat, 4.0 g of carbohydrates, 0.6 g of fibre, vitamin A (1100 I.U), vitamin B (0.20 mg), vitamin C (23 mg), malic acid (150 mg), citric acid (390 mg), oxalic acid (3.5 mg), potassium (268 mg), and phosphorus (27 mg). Tomato is a rich source of minerals, vitamins and organic acid. Tomatoes are the major dietary source of the antioxidant lycopene, which has been linked to many health benefits, including reduced risk of heart disease and cancer. It is used for treating chronic dyspepsia, bronchitis, asthma and also used as a blood purifier. Tomato fruits contain 20-50 mg of lycopene/100 g fruit. Tomatine is a steroidal glycoalkaloid present in tomato. Tomatine content is higher in leaves and f lowers than fruits. Tomatine content is 300 mg/100 g in small hard tomato fruits whereas in large green tomato it is 150mg/100 g. There are various types of f lavouring compounds found in fruits, which enrich the taste;so, several processed items like paste, puree, syrup, juice, ketchup, drinks etc are prepared on large scale. Tomato fruit aroma is due to sulfonium. Tomato acidity is due to citric acid and pH of the tomato juice is 4.5.Tomato is very good appetizer and its soup is said to be a good remedy for patients suffering from constipation. Three f lesh colours are found in tomato, namely, red (lycopene pigment), yellow (carotenoid) and tangerine (prolycopene).Tomato seed oil (24%) is used for manufacture of margarine. About 33% of total tomato growing area is covered by F₁hybrids which is highest among the vegetables grown in India. A book entitled Tomato was written by Dr. G. Kallo in 1986.

1. Potato

Scientific name: Solanum tuberosum L.

Family: Solanaceae

Origin: South America

Chromosome No.: 2n = 4x = 48

Introduction

Potato is one of the four major food crops of the world and is also a very popular vegetable crop. It is extensively cultivated in China, Russian Federation, Ukarine, Poland, Ireland, Great Britain, Germany, Netherlands, France, Spain, South America, India and USA. Potato was brought from Peru to Spain by the Spaniards in 1565 when it was widely grown in Spain and Italy. They were probably brought to England about 1586 by Sir Francis Drake. Potato was introduced in India in early 17^th century probably by the Portuguese. Now it is one of the principal cash crops of India.

Importance and use

• Potato is the fourth major food crops of the world after rice, wheat and maize.
• Being a major source of carbohydrate it is often used as a substitute for cereals.
• It is one of the major vegetable crops of the world and is grown in almost every country.
• In India, it is considered as a staple vegetable and used either alone or mixed with other vegetables.
• Potato is used as vegetable in various forms such as, boiled, mashed, baked, fried and cooked in sambar and different curries of vegetable, fish and meat.
• Potato is processed into different commercially used dehydrated, canned and fried products like, shredded potato, sliced potato, chips, flakes, French fries, finger chips, granules, disc, cubes, flour, etc.
• It is used for several industrial purposes such as production of starch, alcohol, dextrin, glucose, etc.
• Potato starch is a large grained starch and contains 25 % amylase and 73 % amylopectin and high phosphate content.

Potato

Potato, Solanum tuberosum L. under the family Solanaceae (Chromosome No. 2n = 4x = 48) is the most important non-grain food crop in the world, ranking 3rd in terms of total production with over 381 million tonnes per year in (FAOSTAT, 2017), after rice and wheat. It is grown in 150 countries spread across both temperate and tropical regions and at elevations from sea level to 4,000 m. It is extensively cultivated in China, Russian Federation, Ukarine, Poland, Ireland, Great Britain, Germany, Netherlands, France, Spain, South America, India and USA. Potato was brought from Peru to Spain by the Spaniards in 1565 when it was widely grown in Spain and Italy. They were probably brought to England in 1586 by Sir Francis Drake. Potato was introduced in India in early 17^th century probably by the Portuguese. Now it is one of the principal cash crops of India.

The crop

The subsection Potato is distinguished from all other subsections within the genus Solanum by “true potatoes whose tubers are borne on underground stolons, which are true stems, not roots”. The series tuberosa is characterised by “imparipinnate or simple leaves, forked peduncle, rotate to pentagonal corolla and round berries”.

The species S.tuberosum is characterised by “pedicel articulation placed in the middle third, short calyx lobes arranged regularly, leaves often slightly arched, leaflets always ovate to lanceolate, about twice as long as broad, tubers with well marked dormancy period”

Potato is an annual herbaceous plant and growth habit varies between and within species. The plant has a rosette or semi-rosette habit. The stem is erect in the early stage but becomes spreading and prostrate later on. The leaves are compound and alternate, irregularly odd pinnate. The tuber is an enlarged portion of an underground stem or stolon. Tuber eyes are the buds from which next season’s growth will emerge. Eyes are concentrated near the apical end of the tuber, with fewer near the stolon or basal end. Eye number and distribution are characteristic of the variety.

Potato is mainly propagated vegetatively by means of tubers and sometimes by botanical seeds, i.e., true potato seeds. Potato has a terminal inflorescence consisting of 1-30 (but usually 7-15) flowers, depending on the cultivar. The five petals give the open flower a star shape. A flower also has a pistil that generally protrudes above a cluster of five large, bright yellow anthers. The corolla colour varies from white to complex range of blue, red and purple. Flowers are self-pollinated but also cross pollination take place by insect. Seeds are produced in the fruit which is botanically called berry. Potato fruits, stems and leaves contain glycoalkaloids, the toxic compounds, of which the most prevalent are solanine and chaconine.

2.1 Soil and Climate

Pomegranate grows well in sandy-loam and well-drained soils having a pH of 7.5. It can also be grown on light soils. Quality and colour development in light soils is good but poor in heavy soils. It tolerates salinity up to 9.00 EC/mm and sodicity 6.78 ESP. Even it can be grown well in slightly saline soils as it is considered a saline-tolerant plant (Patil and Waghmare 1983; Rao and Khandelwal 2001; Ram Asrey et al., 2002). Accumulation of salts, in excess of 0.5% of the soil mass causes dying off of growing roots. Interestingly, application of Paclobutrazol (250 ppm) was reported to reduce salinity damage (Saeed 2005). The presence of water-soluble salts like sulphates and chlorides and ex- changeable sodium negatively affect root formation.

Abstract

India is one among the major fruit producing countries of the world and offers opportunities of women empowerment through quality fruit production, planting material generation and production of value added products. There is a great opportunity to increase and improve the production of tropical, subtropical, and temperate fruits. Underutilized fruits also have a huge potential waiting to be exploited. This will only be possible with a concerted effort by researchers and growers, especially women to improve quality and increase production based on consumer demand and export potential. Women play significant role in fruit production activities. Unfortunately their access to knowledge, technology, finance, information, and training is minimal which hampers productivity of fruit crops. The mode of female participation in agricultural production varies with the land owning status of farm households. Their roles range from managers to landless labourers. In all farm production, women’s average contribution is estimated at 55 percent to 66 percent of the total labour with percentages much higher in certain regions. About 48 percent of India’s self-employed farmers are women. Thus, rural India is witnessing a process of transition which could be described as feminization of agriculture particularly fruit crop cultivation and their post harvest management. Women play an active role in various production and postproduction activities of horticultural crops. The number of women engaged in horticulture has increased continuously in the past two-three decades due to various factors such as migration of men to urban areas in search of non-farm income, increase in the demand of labour force in construction and other sectors. The data on the women involved in horticulture sector are scanty however the involvement of women in various operations of cultivation and post harvest handling and storage is very high because of entrepreneurial nature of horticulture. There is need to adopt collective and SHG approach to take women contributions to socio-economic significance. Thus horticulture, especially the pre-harvest and post harvest management of fruit crops have considerable employment avenues for women and make horticulture an effective subject of women empowerment.

Biofertilizer is still an unclear term. It can be easily found that biofertilizers are identified as plant extract, composted urban wastes, and various microbial mixtures with unidentified constituents, and chemical fertilizer formulations supplemented with organic compounds. Likewise, the scientific literature has a very open interpretation of the term biofertilizer representing everything from manures to plant extracts.  Quality control of biofertilizers involves several major aspects such as isolation and identification of various strains, screening of the pure isolated strains, fermentation and quality control and finished product.

9.1. Production
Production means creation of value in the goods, i. e. creation of utility. Production activity helps in transforming a set of inputs into goods and services. It essentially means transforming of one set of goods into another. The output generated from production possesses greater utility than the combined inputs used in the production process. The inputs that are utilized in production of goods may be provided by the nature and/ or by other industries.
9.2. Factors of Production
These mean the production resources required to produce a given product. Fraser defined factor of production as “a group or class of original productive resources”. The factors of production have been traditionally classified as land, labour, capital and organization.
Land
According to Marshall, land means “the materials and forces which nature gives freely for man’s aid, in land and water, in air and light and heat.” In Economics the term land has a very broad meaning. It includes all free gifts of nature available to mankind viz., air, water and land. It includes all types of land surfaces such as mountains, valley, plains, forests etc. It includes all types of water resources such as rivers, oceans, etc. Thus the concept of land includes all natural resources on, above and below the earth’s surface.

Productivity automation refers to the use of technology, software, and artificial intelligence to perform tasks automatically with minimal human effort. The main goal of productivity automation is to save time, reduce manual work, increase efficiency, and improve the quality of output. In simple words, productivity automation means using machines and digital tools to do work faster and more accurately. Productivity automation is used in many areas such as business operations, communication, data management, marketing, education, and personal productivity. For example, sending automatic emails, scheduling meetings, generating reports, managing tasks, and analyzing data are all examples of productivity automation. The concept of productivity automation is based on the idea that repetitive and routine tasks should be handled by machines so that humans can focus on creative,

Abstract

The professionals carry additional moral responsibilities as compared to the general population and in society the professionals are capable of taking actions and decisions in a situation which the general public cannot take due to the lack of relevant training and knowledge. Ethics are used world-wide in large companies as well as in small businesses. Ethics is required to be promoted in the work place since it gives employees a sense of trust and worth that can help the business and employees succeed. The client places trust in the professional on the basis that the service provided will be of benefit to them. The purpose of this chapter is to study about need of ethics, types of professional ethics, moral principles of professionals and ethical decision making. Further the study is supported by case studies to make the chapter more relevant.

India has the second largest concentration of tribal population after African continent. The tribal population of India is more than 8 per cent of the total population (Anonymous 2001). However, in Maharashtra it is over 9 per cent of the state population. Among the tribal community Bhil community is the largest tribal population in Maharashtra. They live in compact areas, which are generally hilly and undulating terrain. The Bhil are primarily farmers, though they are said to be hunters since the past. Poor condition of soil, small holdings, poor resources and economic condition, traditional methods of agriculture do not provide them a regular and continuous sustenance throughout the year as such they have to depend on other subsidiary sources of earning.

Most of the tribal communities have to live under a difficult economy; the ways of their livelihood are limited and work very hard to get a bare subsistence. Thus, the tribal children from their early age are burdened with a number of economic duties, obligations and they can hardly be spared for school. Proportion of dropout is also higher among tribal children. In fact most of the tribal youth and school going children participate in farming and looking after the economic demands of the family.

Aim

To determine the reduced levels on various points on the road

To plot the profile of the road

Materials required

Dumpy level

Levelling staff

Theory

Profile leveling is the process of leveling along a fixed line to determine the elevations of the ground surface along that line. The fixed line is generally the centre line of a highway, railway, canal, sewer, etc. The profile leveling is done to determine the undulations of the ground surface. Cross-sectioning is required to determine the levels across the line along which profile leveling is done. Profile leveling should be commenced from a bench mark and should end at a bench mark, as far as possible. When the ground surface does not have many undulations, the intermediate points are fixed at a uniform interval. If the ground surface is irregular and there are abrupt changes in the ground surface, the interval may be non-uniform.

ICT refers to tools that facilitate production, transmission and processing of information. It includes the gadgets and processes to access, retrieve, store, organize, manipulate, produce, present and exchange information by electronic and automated means. According to UNESCO (2004), Information Communication Technology includes a range of technologies starting from radio, television, up to modern technologies like mobile phone, multimedia, internet, and satellite based communication systems. Modern information and communication technologies that have resulted from a breakthrough in information technology, when applied to conditions in rural areas, can help to disseminate information, improve farmers’ knowledge, increase their participation and share knowledge with others. Information Communication Technology (ICT) is one of the yardsticks to measure socio-economic development of the country and hence effective usage and management of ICTs tools is the pre-requisite for any development. Telephone is a powerful electronic device. The number of rural telephones was increased by approximately 35 per cent per annum (Jhunjhunwala and Ashok, 2005). This impressive growth in telecommunication sector is being utilized to provide information on demand to the farming community with the establishment of “Kissan Call Centers” (KCCs).  Kissan Call Centres were launched in January 2004 across the country to provide information services to the needy farmers and answer the queries made by them through telephone. In this context, a study was conducted to find out the profile of Kissan Call Centre users.

Indian seed market is one of the largest in the world and entire supply is through almost locally produced seed. The value of currently marketed seed (excluding the major share of seed saved and used by the farmers) is about USD1 billion (Rs.4500/crore). Of this, roughly a third includes the traded seed making the seed business worth about Rs. 1500 crore. This figure is likely to touch Rs. 4500 crore (USD 1 billion) crore mark by 2010. In comparison to about USD 1 billion seed business in India, the worldwide market of seed is worth about USD 21 billion. The global pesticide market is worth USD 35 billion. These values, however, are much smaller in comparison to global sale of pharmaceuticals worth USD 466 billion.

The study is confined to tribal zone of Orissa, especially of Koraput district where tribes account for 49.69% of the district population. The sample SHG were selected from Sadar, Similiguda and Koraput blocks without any prejudice to their performance. At the outset, it is admitted that SHG has created a sensation among the tribes to look forward the development process. The present study ‘SHG in Techno-Economic Empowerment of Tribal Women’ has been conceived to find out inter-play of technological and economic variables that reflect in social status.

Membership status

SHG starts with the philosophy of micro-approach. Small sized group dynamics, available technology and economic opportunity linked with market structure are the perceived objectives to bring change in livelihood system. The study considered the age of SHG, present membership status, rate of discontinuance as the basic factors of SHG in tribal zone.

The study was undertaken in the state of Odisha. The state lies in between 17^o-31’ to 22^o-27’ North latitude and 81^o-27 to 87^o-30’ East longitude. It is bounded by West Bengal in the north east, Jharkhand in the north, Chatisgarh in the west, Andhra Pradesh in the south and Bay of Bengal in the east. The main features of the state is appeared inTable 3.1.

Abstract

In the present study, the village chicken rearing practices were documented in Kannur and Kozhikode districts of Kerala. A total of 128 native chicken farming households were surveyed. The system of management is extensive backyard type with the provision of shelter at night. Around 90% of the farmers had more than five years of continuous experience in village chicken farming. Majority (73.4%) of chicken present in this region was either reproduced within the household from earlier generations or added from the neighbourhoods of the same Panchayat. Most of the farmers (68.8%) consider that chickens are reared for both egg and meat; while, others (31.3%) deem that they are meant for eggs alone. As many as 87 % of the farmers cull the surplus males before one and half years of age. In contrast, majority of farmers (78.1%) do not cull female birds and usually maintain them till their death.

Biodynamic farming, with its holistic approach to agriculture, has seen significant growth and interest in recent years. This article explores profiles of notable biodynamic farms that exemplify the principles and practices of biodynamic agriculture. It highlights the successes and innovations of these farms, offering insights into their operations, challenges, and contributions to sustainable agriculture. Additionally, the article addresses the startup needs for establishing a biodynamic farm, covering essential considerations such as land selection, certification, initial investments, and resources. By examining these profiles and startup requirements, the article provides a comprehensive overview of the current state and future potential of biodynamic farming.

Nutrients are organic and inorganic complexes contained in the food and it is essential for all living organisms for their normal body development. Macronutrients are the key biopolymers such as proteins, carbohydrates and lipids, which are needed in hefty quantities to provide the bulk of the energy while micronutrients (vitamins and minerals) are required in minor levels in the body; however, are indispensable for proper growth and development of living organisms. Food that cannot provide the right blend of energy including high-quality protein, essential fats, and carbohydrates as well as vitamins and minerals definitely impair growth and development, increase the risk of death from common childhood illness, or result in life-long health consequences. Fish and fishery products form a substantial part of human diet, both of poor and wealthy. Seafood is an excellent resource for proteins, vitamins, trace elements and polyunsaturated fat (omega-3 fatty acids). Profiling of nutrients is very much essential due to the ever-increasing awareness about healthy food which finds more acceptance towards the consumption of fish and fish products owing to its special nutritional qualities.

Suppose you go to a Big Bazar to buy a shirt. You finalize the shirt and are shocked to see its price tag. The price mentioned on the sweatshirt is Rs. 2500. You ask the owner to give some discount. He offers a discount of 20%. Now just figure out, how much you will pay to the shopkeeper. Did you say 2000 rupees? You are bang on1 You will pay a sum after subtracting 20% of amount written on price tag i.e. Rs. 500 from Rs. 2500. You finally pay the shopkeeper 2500 – 500 = Rs. 2000. This example introduces you to the concept of marked price and discount. What you indirectly learned from this case is that the discount is calculated on the marked price only. Now let us assume here that the shopkeeper has purchased that sweatshirt for Rs.1600. How much money that shopkeeper has earned by selling this sweatshirt ? Now the shopkeeper has invested Rs. 1600 to buy this sweatshirt and finally sells for Rs. 2000. He makes a profit of Rs. 2000 – 1600 = Rs. 400

He earns this profit by putting in Rs. 1600. Thus his percentage profit is 100 x 400/1600 = 25%. This makes another concept of cost price and profit clear to you i.e. the price you put in from your pocket to buy a product is called cost price and the extra amount you get after selling the product is called the profit. The profit and loss percentage is calculated on cost price. Profit and loss problems are an integral part of all the competitive exams. You must understand the meaning of the basic terms used in profit and loss questions.

Introduction

Agriculture is the backbone of Indian economy. There are a number of sub sectors in the agricultural sector such as sericulture, floriculture and horticulture. Among those fields horticulture has played a dominant role in the total agricultural output throughout India. The world market has provided a good opportunity for the development of the fresh and the processed fruits industry of India. From the point of view of domestic market also, horticulture products have provided food items of nutritional value. Their cultivation has generated higher employment opportunities and higher returns to the farmers than the cereals and other agricultural cash crops (Singhal, 1995). Mango (Mangifera indica) is a stone fruit belonging to family Anacardiaceae. It is a most important fruit of India and known as the “king of tropical fruits”. Mango is cultivated in many tropical regions and distributed widely in the world. 

Introduction

Agriculture is India is mostly production oriented restricted in huge number of uneven small holdings and plays a key role in the Indian economy. Cultivation of fruits and vegetables has emerged as profitable venture and it is not only providing nutritional security but also provides a substantial employment to rural people as well as open the door for export. India is the second largest producer of vegetables, next only to China, in the world with a production of 40 million tonnes from four million hectares of land area. In India, vegetables are grown in an area 1, 10, 65 thousand hectares with the production of 1, 99,882 thousand metric tonnes. Uttar Pradesh is the largest producer of vegetable production in the country (14.80 %) followed by West Bengal (14.12 %), Madhya Pradesh (10.30%), Bihar (8.88 %), Maharashtra (8.39 %), Gujarat (7.84 %), Odisha (4.76 %) and Karnataka (4.05 %) (NHB, 2021).

Bennett’s Hierarchy

To set the scene for this we head back to the 1970s when Claude Bennett worked as a specialist in evaluation with the extension service. He wanted to make sure that extension was collecting information that was able to illustrate the effectiveness of extension, and help extension improve its services to clients. So, he developed seven categories of criteria for evaluating extension programmes based on what he called a ‘seven link chain of events. He put these into a hierarchy literally in his article describing this-as a diagram of seven steps.

Theory

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.

Introduction

Programme for self-employment of the poor has been an important component of the anti-poverty programmes implemented through government initiatives in the rural areas in India. The Swarnjayanti Gram Swarozgar Yojana (SGSY) is the major ongoing programme for the self-employment of rural poor at present. The programme was started with effect from 01.04.1999 after restructuring of Integrated Rural Development Programme (IRDP), and allied programmes namely Training of Rural Youth for Self Employment (TRYSEM), Development of Women and Children in Rural Areas (DWCRA), Supply of Toolkits in Rural Areas (SITRA) and Ganga Kalyan Yojna (GKY) and Million Well Scheme (MWS). Govt. of Orissa have launched ‘Mission Shakti’ programme in 2001 with an aim to have at least three lakh WSHGs by the end of 2008. By the end of March 2008, 3.73 lakh WSHGs have been formed under Mission Shakti (Annon, 2007-08). SGSY has contributed substantially in carrying forward the Mission Shakti activities in the state. A study was conducted by the Center for Management and Development, Thiruvananthapuram for concurrent evaluation of the implementation of the SGSY. It was established that the performance of SGSY in Assam, M.P., Orissa, West Bengal and Bihar was the lowest among the major states (Anon, 2002-03). SGSY is implemented in a very deterministic and top down manner, ignoring the participatory approach that is envisaged in the design. Good governance for poverty alleviation programme seems to be more of rhetoric than reality (Shylendra and Bhirdikar, 2005). The Ministry of Rural Development, Govt. of India has set guidelines for successful implementation of the scheme within the framework of targets under each head. As per the guidelines, all the states are directed to fulfill the targets. After 10 years of implementation of the scheme, an evaluation of the programme in district level and state level is in dire need. Hence, it is attempted to evaluate the physical and financial achievement of the SGSY programme operated at Orissa.

An important decision that the management has to take during implementation of the process of evaluation is about which model to choose. The choice of a single model will mainly depend on the nature of the problem or the situation in an organization. However an integrative approach using more than one model may also be used. Before implementation of any of these models and before the actual process of evaluation starts it is important to make suitable preparations and create a conducive environment in the organization for successful conductance of the evaluation. The following points are to be taken
in to consideration before and at the time an evaluation is carried out in an organization:

Programme evaluation requires appropriate frameworks that can connect programme resources and activities with measurable learning, behavioural and developmental outcomes. This chapter presents two important tools for agricultural extension evaluation: Bennett’s Hierarchy of Evaluation and the Logical Framework Approach (LFA). Bennett’s Hierarchy provides a structured progression from programme inputs and activities to participation, learning, behavioural change and ultimate social, economic and environmental results. Its particular value in agricultural extension lies in linking educational interventions with observable changes among farmers and communities. The chapter explains its conceptual foundation, seven levels, applications, advantages and limitations. The Logical Framework Approach is introduced as a systematic tool for programme planning, monitoring and evaluation. It organizes programme goals, purposes, outputs and activities within a logical results framework and incorporates objectively verifiable indicators, means of verification and assumptions. The chapter also discusses participatory logical frameworks, Results-Based Management, Outcome Mapping, Theory of Change, Goal-Oriented Project Planning and Objectives-Oriented Project Planning, thereby providing complementary approaches for designing and evaluating development programmes

Effective agricultural extension programmes require systematic planning, scheduling, coordination and monitoring of activities. Programme management techniques provide practical tools for organizing resources and activities so that programme objectives can be achieved within defined time and resource constraints. This chapter introduces important techniques used for planning and managing agricultural development and extension programmes, with particular emphasis on SWOT analysis, bar charts, network techniques, Programme Evaluation and Review Technique (PERT), and Critical Path Method (CPM). SWOT analysis provides a structured approach for examining internal strengths and weaknesses along with external opportunities and threats affecting a programme. Bar charts and Gantt charts assist in presenting activities against time and monitoring programme progress. Network techniques provide a more systematic representation of relationships among programme activities. PERT is particularly useful where activity durations involve uncertainty, while CPM helps identify critical activities, scheduling constraints and opportunities for time and cost optimization. Together, these techniques provide extension professionals with practical methods for programme planning, scheduling, resource utilization, monitoring and management

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.
