Demand for fodder in intensive livestock farming necessitates the fodder seed production in all the livestock and fodder farms for their own use and sale to needy. In the recent past, fodder seed production is also becoming commercial activity of farmers as the income is promising. Since, there are number of new varieties of fodder are coming to the market, demand for their seed is also encouraging to produce the same commercially. Considering this, the farm managers should aware of fodder seed production technologies for cost effective and quality fodder seed production.

During the last visit of Barak Obama in the year 2011, he pointed out that India is fortunate to have a youth population with a half of the total population being under the age of 30-35 years. Out of 600 million young people, over 60% live in villages and majority of them are educated. Mahatma Gandhi considered that migration of rural youth from villages to town and cities as the most serious form of brain drain affecting adversely rural India’s development. The National Commission on Farmers stressed the need for attracting and retaining rural youth in farming. Recently, National Sample Survey has indicated that over 45% people want to quit farming under these condition there is need to persuade educated youth including farm graduates to stay in villages and take up agriculture as a profession. There are various economic opportunities for farm graduates which are discussed below:

Sincehundreds ofyears, Livestockanimals arean integralpart ofcrop–livestock system. In the life style of Indian people, livestock had always been given a special and respectful place and this will continue in the years to come. Despite considerable deficit of feeds, the above may be one of the reasons of steadily increasing livestock production in our country. Almost all assessments made during the past eight decades, have shown deficits of different orders in respect of following for the availability of :

• Dry fodders

• Green fodders and

• Concentrates

Such surprising phenomenon is inviting our attention for reviewing systems of assessment for finding out the status of consumption and the gap between the above. Production of milk, meat, fibre, chicken and eggis increasing, though. Therefore, there is gap between the availability and requirements of different feeds. Because India is facing shortage of both protein and energy rich animal feeds, a large number of agro – forest based unconventional by products have been used. Some of these feeds were found to be promising, while others affected the performance of the animals, due to presence of incriminatingfactors present in them. But after detoxification, these feeds were suitable for animal feeding. Some of these feeds are :

Ethylene (C₂H₄ also known as ethene) is a gaseous organic compound that is the simplest of the alkenes chemical structures (alkenes contain a carbon-carbon double bond). The hormone effects of ethylene on general plant growth were first noted in 1864 when leakage from gas street lighting systems caused stunting and deformation of nearby plants. In 1901 Neljubow identified the active component of the gas to be ethylene but it was not until 1934 that Gane identified that plants could synthesize ethylene and in 1935 Crocker proposed ethylene to be the hormone responsible for fruit ripening and senescence of vegetative tissues.

Ethylene play important role in many plant during development processes, including seed germination, vegetative growth, leaf abscission, flowering, senescence and fruit ripening. Ethylene also plays a role in response to water stress, chilling and mechanical injury.

Perennial fruit trees build their woody architecture with some building blocks, i.e. modular units, known as metamer or phytomer (White 1979; Room et al., 1992; Hare Krishna, 2012). It consists of meristems initially an apex. When a meristem faces periods of dormancy during low temperature or pruning, later it appears as bud, whenever active, as such bud produces a growing point with sequence of meristematic tissues simultaneously called a sprout, i.e. extension unit or growth unit (Halle et al., 1978; Bell, 1991). The driving mechanism behind the pattern appears to be auxin production (and basipetal transport) when new shoots and leaves developed and are exposed to light (Sterck, 2005). Other feature of trees are to produce more xylems relative to phloem, accumulate xylem over time and may thus produce thick woody branches and stems. Further, attaining reproductive phase and reproduction processes compete with vegetative functions, depleting resources necessary for maintenance and growth (Fakhri et al., 1987).

The idea that reproduction, growth and defence interact within the individual and compete for limited resource is now considered an established principle. Because there are trade-offs between a plant’s various functions and the concept of source, and sink helps to explain allocation patterns at both the physiological and evolutionary levels. Logical approaches have extended this hypothesis to an explicit as source and sink framework in which the effects of defence allocation on rates of consumption can be weighed against the effects on growth (Coley et al., 1985; Mooney and Gulmon, 1982; Fakhri et al., 1987). The allocation to vegetative structures has compounding interest for plant growth, as plant life-cycles begins with pure vegetative growth (Abrahamson, 1979), also consistent with the idea that perennials must forego some reproductive expenditure to retain sufficient resources for perennation.

Quality Control is very important in biofertilizer production, which determines the efficiency of microbial strains. Generally, the quality control based on BIS are voluntary in nature. However, some of the biofertilizers are brought under the ambit of Fertilizer Control Order 1985 (FCO) during 2006 (Yadav and Chandra, 2014). At present, biofertilizers are under the FCO with specific quality standards. Biofertilizer production and its sales can be regulated and is a mandatory requirement for registration of manufacturing unit with the State Fertilizer Controller (who is generally the Commissioner or Director of Agriculture Department) under the statutory provision of FCO. Moreover, some officers of the Agriculture Department have been declared as Fertilizer Inspectors at the district level, who are authorized to inspect production and storage facilities and draw samples for quality analysis. National Centre of Organic Farming (NCOF), Ghaziabad under the Govt. of India and its six Regional Centre’s located at Bhubaneswar, Bangalore, Jabalpur, Nagpur, Hissar and Imphal have been declared as testing laboratories. Under the provisions of the FCO act, State Governments can also develop their own quality control laboratories and notify them under the FCO (1985). Peat, lignite, peat soil, humus, wood charcoal or similar material favouring the growth of microbial strain could also be used. The FCO specifications for different biofertilizers are presented below:

Jaundice is a disease marked by a yellow discoloration in the skin, or in the whites of the eyes. This is due to excessive amounts of bile in the blood stream. Jaundice may arise from a number of different causes. Some types of jaundice arise from conditions outside the liver. Also in some cases the patient may have jaundice in a sub clinical form. That is, the bile pigment may be elevated but not sufficiently to actually discolour the skin.

Normally there is a certain rate at which the red blood cell are broken down and destroyed in the body. The average life of a red cell is about four months. But certain disease conditions may cause an excessive breakdown of red cells and this increases the bile pigment in the blood. Such a rapid breakdown of cells may be seen in haemolytic anaemia, sickle cell anaemia, pernicious anaemia, jaundice of the newborn child, as well as in malaria, pneumonia, yellow fever and certain bacterial infections of the blood.

Obstructive jaundice means that the bile is backing up into the blood stream because of some obstruction involving the larger bile ducts. The normal liver produces one pint of bile every twenty-four hours. This is transported to the gall bladder where it is concentrated and becomes green, or else passes directly to the small intestine where it acts as a lubricant. Bile is also necessary for the absorption of fats and for its laxative effect in the large intestine.

Introduction

The durian is an important fruit in several parts of the tropics and is the famous fruit of the far East, where it is widely cultivated throughout Malaysia. It is indigenous to Malaysia, i.e., South East Asia, and is distributed in Malaysia, Indonesia, Philippines, Thailand, Singapore, Kampuchia, Myanmar, India, and Sri Lanka. The term durio is the Malaysian word duri-thorn, and zibethinus is the Italian word for “zibetho,” meaning “strong-smelling. Thus, this is a fruit characterised by a greenish, hard, thick rind on the outside and a yellowish, sweet flesh with a strong odour. The fruits are nothing but seeds covered with a cotton-like fibre.

Inroduction

The process of connecting neutral point of 3-phase system to earth (i.e. soil) either directly or through some circuit element is called neutral grounding. Neutral grounding provides protection to personal and equipment. It is because during earth fault, the current path is completed through the earthed neutral and the protective devices (e.g. a fuse etc.) operate to isolate the faulty conductor from the rest of the system. This point is illustrated in Figure 10.1.

Figure 10.1 shows a 3-phase, star-connected system with neutral earthed. Suppose a single line to ground fault occurs in line R at point F. This will cause the current to flow through ground path as shown in Figure1. Note that current f lows from R phase to earth, then to neutral point N and back to R-phase. Since the impedance of the current path is low, a large current flow through this path. This large current will blow the fuse in R-phase and isolate the faulty line R. This will protect the system from the harmful effects of the fault. One important feature of grounded neutral is that the potential difference between the live conductor and ground will not exceed the phase voltage of the system i.e., it will remain nearly constant.

23.1. Aim

To determine the total soluble solids in fresh and processed fruit and vegetable products.

23.2. Theory and principle

Total soluble solids (TSS) are determined by means of brix which measures the specific gravity or by using hand refractometer which measures refractive index. Brix is a measure of soluble solids only in case of pure sucrose solutions. Generally, the fruit juices contain more sugar than any other soluble constituent. Hence, brix provides a useful guide of soluble solids or sugar contents. Brix hydrometer is used to determine the percentage of brix in syrup while Abbe refractometer gives refractive index as well as degree brix. The Refractive index of the test solution is measured at 20°C using a refractometer and the soluble solid content is determined by the use of tables correlating refractive index with soluble solids. Generally, hand refractometer is used for determining TSS in food samples in fruit processing units (Table 3.1).

Indian farming community is dominated by the marginal and small farmers who account for nearly 86 percent of farm holdings in India. As these farmers have small land holdings of less than 2 hectare, their income from farming is meagre and not sufficient to meet family expenses (Lalji et al., 2019). As a result, these farmers often follow family income augmentation strategy either by taking land on lease, working as wage earner or livestock rearing. Among all these family income augmentation activities, livestock rearing is the most frequently adopted strategy they undertake to augment their family income. It is observed that in India in general, farmers follow livestock integrated farming system (Paramesh et al, 2022). Popularity of livestock activity to augment farm family income of poor farmers is due to synergy of livestock rearing with the farming. Agriculture waste in the form of green and dry fodder contribute important inputs in livestock rearing. Whereas, farm animals are important source of farm energy needed for cultivation. Livestock waste helps in maintaining soil fertility and protein supply to farm families. Animal rearing also help in managing cash flow for farm family as it generates cash from the sale of milk and other animal products on the daily basis. Sale of live animals help in meeting contingency expenses of farm family. Thus, it solves peculiar problem of farm family cash paradox where farmer gets income through sales of agriculture harvest only during harvest season which happens only two / three times in a year but he needs cash on daily basis to meet his other health, educational, social etc. family needs.

Introduction
India possesses the largest livestock population globally. To sustain this extensive livestock sector, it is essential for the country to ensure a corresponding supply of feed and fodder that meets the growing demand. However, a significant barrier for enhancing livestock production in India is the inadequate availability of feeds and fodders, both in terms of quality and quantity. The limited land designated for cultivation approximately 3.3-4.4% of the total cultivable area coupled with the decline in pasture lands and a shift in cropping patterns from coarse cereals to commercial crops, poses substantial risks to fulfilling the nation’s feed and fodder requirements. A considerable portion of the coarse cereal byproducts is utilized as fodder. Projections indicate a shortfall of 28% to 35% in green fodder, 10% to 11% in dry fodder and 33% to 35% in concentrates (Niti Aayog, 2018). The current status of feed and fodder resources is insufficient to meet the rising demand. Proper feeding is vital for the improvement of livestock breeds, as inadequately fed improved breeds tend to deteriorate more quickly. Consequently, there is a persistent imbalance between the number of animals and the available feed resources.

Ice Caps : A perennial ice/snow cover over an extensive area of land or sea, found only around the two geographic poles.

Ice Columns : Ice crystals resembling stubby pencils rather than the delicate branched snowflake shape. Columns typically form in the temperature ranges -5° C to -8° C (23° F to 18° F) and below -25° C ( -13° F). They are long in comparison to their hexagonal cross-section.

Ice Crystals : 1) Hexagonal (6-sided) crystals that form upon freezing of water, may be in one of several shapes : stars, needles, plates, columns or combinations of these forms. 2) Precipitation in the form of slowly falling, singular or unbranched ice needles, columns, or plates, may be called diamond dust.

Ice Fog : Fog composed of minute ice particles that occur in very low temperatures (typically - 30°C or - 22°F & below) under clear, calm conditions in the polar latitudes. 

Gas Chromatography (GC) was discovered in 1954, a verysensitive technique, whichpavedwaytothisworldfor the resolution ofthe sampleleadingtodetection … identification of the minutest quantity of the desired sample.

Fattyacids were usuallyconverted into correspondingmethyl esters (FAME) to improve volatility and to reduce peak tailing for GC. Usually, FAME could be conveniently prepared by heating lipids with a large excess of either acid- or base-catalyzed reagents. Whereas, acid-catalyzed reagents form FAME from both free fatty acids (FFA) and O-acyl lipids base-catalyzed reagents caused only transesterification, i.e. conversion of O-acyl lipids to FAME and do not usually form FAME from FFAs. A base-catalyzed reaction was a useful alternative to acid-catalyzedreactions whena lipid sample contained acid-labile FAs such as propenoids, present in seed oils from the Malvales order, such as cottonseedoil. To effect solublizationof nonpolarlipids such as triacylglycerols in methanol. the predominant solvent in derivatization reagents, benzene was frequentlyadded to the derivatizalion reaction mixture. However, due to health concerns, use of benzene was discouraged. To help solubilize nonpolar lipids, methylene chloride and tetrahydrofuran had been used in place of benzene.

Harvesting is the act of removing crop from where it was growing and moving it to a more secure location for processing and storage. Some root crops and fruits trees can be left in the field or orchard and harvested as needed, but most crops reach a period of maximum quality that is they ripen or mature and will deteriorate if left exposed to the elements. While the major factor determining the time of harvest is the maturity of the crops and other factors such as weather, availability of harvest equipments, packing, drying, transport and storage facilities.

Economic and marketing issues are often even more important to consider when to harvest commodity. Before harvesting of crop, grower must be sure about demand of the produce.

Harvesting the crop at optimum maturity is critical for reaping the benefits of season long efforts on crop production. After final decision on crop maturity, care must be taken to avoid losses during harvest, threshing, transport and storage. Processing is equally important to keep the produce in good condition for realizing good price.

Crop maturity: There are different types of maturity namely physiological maturity, harvest maturity and storage maturity.

Physiological maturity: It is the stage of development in the life cycle of plant when the plant reaches maximum dry weight. At this stage any further increase in inputs does not produce any gain in yield. There is cessation in growth and grain filling at this stage. Grain at this stage has 40 per cent moisture and 90 per cent produce is matured and this remaining 10 per cent still immature. So farmers should harvest at stage to get maximum benefit.

Potassium (K) is among the most important essential macronutrients for plant growth. About 98% of the potassium in the earth’s crust exists in insoluble forms as rocks and silicate minerals, resulting in very low concentrations of soluble potassium in the soil for plant growth and development. Potassium is never incorporated in any organic compound and even in the plant system it remains as K⁺ ion. It does not form any gas that could be lost to the atmosphere. It does not cause eutrophication. When left in the ecosystem as such, it is not at all toxic.Potassium activates enzymes, maintains cell turgor, enhances photosynthesis, reduces respiration, helps in transport of sugars and starches, and is essential for protein synthesis. In addition to plant metabolism, potassium improves crop quality because it helps in grain filling and kernel weight, strengthens straw, increases disease resistance and helps the plant better to withstand stress.

Potassium in Soils

Soils usually contain potassium in larger amounts than any other nutrients. Total K content in soil is 30,000- 50,000 kg/ha in top layer of the soil. Nearly 98 % of K bound in the mineral form and 2 % is in soil solution. Generally, potassium in soils exist in four forms (often called fractions), their availability to crop roots is considerably different.

The common stones found in the kidneys are of calcium oxalate, uric acid, urates, triple phosphates or a combination of these.

The patients are often males between 30 to 50 years.

Horticulture includes variety and diversity of crops. Thus, it can be divided into several branches depending upon the crops it deals with. Following are the branches of horticulture.

1. Pomology: The term pomology is a combination of two Latin words pome i.e. fruit and logos i.e. science. Recently it has been designated as ‘Fruit Science’. It deals with the study of fruit crops. It includes all aspects of fruit crops e.g. importance, uses, origin and distribution, area and production, soil and climate requirement, botany, nursery raising, cultivation practices, plant protection measures, stage and methods of harvesting, post-harvest handling, marketing, export, import, etc. e.g. mango, banana, citrus, grape, apple, peach, pomegranate, fig, etc.
2. Olericulture: The term olericulture is also derived from the Latin word. Cultivation of vegetable crops. Recently it has been designated as ‘Vegetable Science’. Vegetables are said to be herbaceous plants of which edible plant parts are used for consumption either cooked or salad. It may be stem, root, leaf, flower, etc. It also includes all aspects of vegetable crops e.g. importance, uses, origin and distribution, area and production, soil and climate requirement, botany, nursery raising, cultivation practices, plant protection measures, stage and method of harvesting, post-harvest handling, marketing, export, import, etc. e.g. tomato, brinjal, chilli, cucumber, red pumpkin, watermelon, cabbage, cauliflower, etc.
3. Ornamental Horticulture: It includes various groups of ornamental plants used to decorate in-door and out-door areas. Ornamental horticulture is the study of growing, arranging and tending decorative plants and flowers. It is further divided into.
