General Terminologies in Livestock Production

The world’s largest population of milch cattle lives in India. In 2020, there were almost 906 million tones of milk produced worldwide, with India being the top producer with a 22 percent share. Annual Growth Rate of milk production in 2019-20 in India was 5.69 per cent. Highest growth rate in milk production was found to be 14.31 per cent in Karnataka. In 2021, the Indian dairy market had a value of INR 13,174 billion.

Meat is considered as well balanced diet because it is good source of macro and micro nutrients.

Macronutrients-required in large quantity in body i.e proteins, fat and carbohydrates.

Micronutrients-required in lesser quantity by human body i.e vitamins, minerals and fibers.

Organ meat like liver is a good source of glycogen, viatm-A, B1 and nicotinic acid.

Fresh meat is unprocessed.

Raw meat is a fresh meat undergone chilling and freezing.

Refrigeration and rapid cooling can delay the onset of rigor mortis

Introduction

Animal waste or manures are the solid, semisolid, and liquid generated by the animals reared for the diverse aims such as production of milk, meat eggs and for other agricultural work. Animal wastes comprises of faeces urine, bedding materials (straw, sawdust, rice hulls), and other materials associated with animal production, such as leftover feed, soil, wash waters and any chemical or physical amendments used during manure handling and storage. An adult bovine weighing 400 kg approximately discharge 15-20 kg dung and 15-20 liters urine per day. The dung produced is discharged from the farm leads to the clogging of drainage pipes and act as a breeding site for the mosquitoes. Additionally, the animal manure contains a wide range of microorganism which can be hazardous to the health of humans and animal. These microorganisms can contaminate food, epidemics and risk to the public health. Contrary to this animal manure are eco-friendly source of plant nutrition to enrich & restore soil nutrients, conserve the micro-fauna of soil and act as a natural surface purifier. Dung manure contains basic elements critical to plant health i.e., nitrogen (N), phosphorus (P), and potassium (K) and several micro nutrients. Also, animal manure imparts beneficial qualities to the soil such as improves the physical and biological properties of soil, improves aeration and thus enhance the water holding capacity. However, in recent pass it has been observed that a lot problem of environment arises due to nitrates present in manure connected with irrational use of natural fertilizers used in the agriculture land. The natural fertilizers contain large quantity of organic nitrogen which coverts in to inorganic form through the process of mineralization and possess a serious risk to the environment. In addition to this the nitrogen may leach to the ground and surface water as compared to chemical fertilizer.

Abstract

India is an agriculture based country and livestock production is an integral component of farming system and it is generally considered a key asset for rural livelihoods. It offers advantages over other agricultural sectors and it plays a crucial role in the rural economies of developing countries like India. Livestock provide high quality food, cash income and employment. Livestock production is largely in the hands of women. Most of the animal farming activities such as fodder collection, feeding, watering, and health care, management, milking and household-level processing, value addition and marketing are performed by women. Besides, considerable involvement and contribution of women, gender inequalities also exist in Indian villages. Therefore, there is a need to correct gender bias in livestock sector. Efforts are needed to increase the capacity of women to negotiate with confidence and meet their strategic needs.

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

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

Aim

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

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

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

Local Anesthetic Techniques of Head Region
The following nerves can be blocked in the head region for performing surgery.
    1.    Cornual nerve block 
    2.    Peterson’s orbital nerve block 
    3.    Auriculopalpebral nerve block 
    4.    Supra orbital nerve block 
    5.    Infra orbital nerve block 
    6.    Retro bulbar nerve block 
    7.    Mental nerve block 
    8.    Maxillary nerve block 
    9.    Mandibulo alveolar nerve block 

These are the drugs that reversibly block the propagation of action potentials along nerve axons. General anesthesia may be advantageous where complete immobilization and relaxation of the patients required. However, local anesthetic techniques are advantageous for providing surgical anesthesia in animals that are considered at risk for inhalant or intravenous anesthesia. These drugs are injected directly at the target site.

ABSTRACT

The Indian false vampire bat, Megaderma lyra detects and captures prey (e.g. frogs) mainly by listening to the rustling sounds that are created when the prey is on ground. In addition, echolocation and vision are also involved. Mothers of M. lyra take meticulous care of their young. At the age of about seven weeks, juveniles exhibit gleaning flights. Among eight mother-young pairs, four young (group A) began to capture frogs at the age of 62 days

3.1 Introduction

Different types of farm ponds with their characteristics features are discussed in this Chapter. It is observed that farm ponds can be constructed at different sites starting from the plain areas with relatively flat slopes to valley terrain having steep slopes. The choice of a particular type of pond largely depends on the kind of water supply available and on the existing topography of the site selected. In general for valleys with bottom width less than 100 m, barrage ponds may work well whereas valleys with bottom width more than 100 m, diversion ponds find suitable.

3.2 Collection of Basic Information

Basic information on different data relating to the soil, climate, plant, topography, groundwater table, catchment characteristics, and livestock populations are to be collected for the area where pond has to be constructed. Estimation of water supply from different sources and water demand form the pond for various purposes are to be done and a pond water balance study needs to be done before designing a pond in a particular place.

16.1 Introduction

Fish are primarily designed to swim in the water. Their fusiform body allows for efficient swimming. Swimming is the most cost-effective mode of fish locomotion because fish bodies are supported by water and thus do not require energy to counter gravity. To swim, a fish uses its fins. The caudal fin is primarily used for propulsion, while the remaining fins are used for balance control and f ine maneuvering. However, some Plectognathi fish (Trunk-fish, Parrot-fish, Butterfly-fish, Porcupine-fish, and Trigger-fish, among others) have lost their ability to swim using body flexure and can only move with their other fins.

Locusts are injurious to man as it destroys several human commodities. Locusts are phytophagous and feed on several plants cultivated by man. The locusts are insects belonging to the order orthoptera. The most popular insect is grasshopper. The only difference between the two types of insects is that locust can exist in two different behavioural states whereas grasshoppers do not. When the population density is low locusts behave as individuals, much like grasshopper. As the population density is high locusts gregariously behave as band of nymphs or swarms of adults. The changes in body shape and colour and in fertility, survial and migratory behaviour are accompanied by phase change. The most important locust species is the desert locust (Schistocerca-gregaria). The international pest influences various parts of Asia, Africa and Europe. Other locust species are highly injurious to mainkind like Bombay locust and Indian migratory locust (Locusta- migratoria) found all over India in its solitary phase. The monsoon months in July and August suitable are for locust multiplication conditions. The new generation produced migrate eastward into the Indian desert areas in May and June.

Logical Framework Approach (LFA) Background and Description, Variation of LFA

Definition The Logical Framework Approach or LFA is a systematic and analytical process for objectives-oriented project planning and management

Background: The Logical Framework Approach (LFA) was developed for USAID in the 1960s. Since then, it has been adopted and adapted by many other international development organisations. Among them was the German agency GTZ, which derived its Goal-Oriented Project Planning (ZOPP) from it.

Logical Framework Approach (LFA) is a framework for designing change process, monitoring progress and evaluating impact. It is a powerful tool for project design, management, assessment, follow up and evaluation of projects. In designing change process, monitoring progress and evaluating impact, ordering the change process in a logical sequence where inputs or resources identify as necessary means for performing activities are very important. Specific activities are then identified because they result in outputs which are necessary to achieve objectives. The two terms i.e.; log frame and logical framework approach are sometimes confused by many. The log frame is a document whereas the logical framework approach is a project design methodology. LFA originally developed by the American Defense Department and was first formally adopted as a planning tool for United State Agency for International Development (USAID) by the end of 1960’s and today it is being used, in one form or other and with different names, by major organisations in the field of development co-operation and private industry. Among these are British DFID, the OECD expert group on Aid Evaluation, ISNAR International Service for National Agricultural Research, Germany’s GTZ and the Inter-American Development Bank. It has also been widely adopted by NGOs, though not without reservations and concerns by some. In the 1990s it was often mandatory for aid organisations to use the LFA in their project proposals.

Origin and Distribution

The plant is native to the Caribbean islands occuring from S.Mexico to Panama, Columbia, Bolivia, Brazil and Cuba to Trinidad. It was introduced to many tropical and subtriopical countries  where it is used as a substitute for coriander.

Conservation of released varieties requires a sound scientific and technical basis. There are two main strategies for conserving agricultural biodiversity, namely ex-situ and in-situ conservation, both of which are equally important. In-situ conservation refers to the maintenance of a species in its natural habitat. Exsitu conservation is the conservation of components of biodiversity outside their natural habitats. It is conserved in the form of seeds (seed gene bank), live plants (field gene bank), tissues (tissue gene bank), pollens (pollen gene bank) and DNA materials (DNA bank). 

The experimental design and analysis discussed in previous chapters refer essentially to experiments on annual crops. Even when these experiments are repeated in different years, this is done at a new site each year .The use of new crop production practices will generally change the important physical and biological factors of the environment. This process of change can take many years. Generally, the productivity of some types of technology must be evaluated by a series of trials repeated over time. Such trials are generally referred to as long-term experiments. Long-term experiments are those which are continued on the same set of plots over a series of years with a pre-planned sequence of treatments or crops or both. Treatments may be applied every year or periodically. The same crop may be repeated year after year or once planted may continue for several years as perennial trees ,or a sequence of crops may be grown in rotation as for instance rice-rice or rice-wheat (1 year sequence with 2 crops per year ) or sorghum,groundnut,cotton and wheat, each crop cycle being completed in four years. The main features of long-term experiments are as follows :

Abstract

Twelve different cyanobacteria strains from different locations in Syria were collected and analyzed. They were identified as strains from Anabaena, Nostoc, Phormidium and Chroococcus. All strains produce mycosporine-like amino acids (MAAs) as UV-screens upon UV-radiation. Composition of the MAAs and amount of UV-induced MAA production differ between the strains. In order to evaluate the long-term stability of completely encapsulated cyanobacteria aliquots were transferred into hermetically closed vessels. The survival was non-invasively determined by means of pulse-amplitude modulated fluorescence and by delayed fluorescence detection. It was found that 4 strains (one Chroococcus, two Anabaena and one Nostoc species) show photosynthetic performance after 4 years of encapsulation. In addition, many cyanobacteria are desiccation tolerant and are able to fix atmospheric nitrogen. They may play an important role in biological life support systems e.g. in space research.

Longan (Dimocarpus longan Lour), belongs to the family, Sapindaceae. It is a hardy subtropical fruit tree very similar to litchi in habit and appearance. The longan is native to southern China, in the provinces of Kwangtung, Kwangsi, Schezwan and Fukien. The longan is less important to the Chinese as an edible fruit, more widely used than the lychee in Oriental medicine. It is also now widely grown in Thailand, Hong Kong, Taiwan, Vietnam, Myanmar, Indonesia, Malyasia, USA, New Zealand and Australia. The longan was introduced into India in 1798. In India it is mainly grown in Western ghats, Assam and West Bengal.

Cultivars: Most important cultivars of major Longan growing areas of world are Ilao, Wai, and Fuhko No. 2.

Food Uses

Although longan is mainly used for dessert purpose. It can be dried, frozen or canned. Preserved longans are considered by many as superior to preserved litchi, the flavour being more delicate. Longans are much eaten fresh, out-of-hand, but some have maintained that the fruit is improved by cooking. In China, the majority are canned in sirup or dried. The canned fruits were regularly shipped from Shanghai to the United States in the past. Today, they are exported from Hong Kong and Taiwan.

The dried longan product is black, leathery and smoky in flavor and is mainly used to prepare an infusion drunk for refreshment. A liqueur is made by macerating the longan flesh in alcohol. (Morton, 1987).

Genus : Euphoria/Nephelium/Dimocarpus
Species : longana (Lour.) Stend. cinerea
Family : Sapindaceae
Chromosome No. : 2n = 20

The longan (Euphoria longana) belongs to the Sapindaceae or soapberry family to which more important fruits like litchi and rambutan also belongs. The family contains more than 1000 spp. from 125 genera widely distributed in the tropical and warm subtropics. Most of the species are native to Asia though some are also found in south America, Africa and Australia. The genus has seven species but only longana is both horticulturally and commercially important as it yields/produces edible fruits. For most of the growth, flowering and fruit characters it is similar to the two above horticultural crops mentioned. In respect of soil and climate it is less demanding and does adapt or tolerates drier and cooler condition better than litchi.

3.1 Control statement in python

Python statements are executed one by one in the same order as they appear in the program. But there may be some requirement when we want to execute the statements based upon a condition. Even there may be some situation where we want to execute a single statement or multiple statement (block of statement) “n” times till the condition is true. So in order to control the flow of execution of the program python provides us control statements.

There are two types of control statements:

(a) Selection statement

(i) if

(b) Looping condition

(i) While (ii) for

The loquat, Eriobotrya japonica Lindl., (syn. Mespilus japonicus Thunb.), belongs to the rose family, Rosaceae. It is also called Japan, or Japanese plum and Japanese medlar. The loquat is indigenous to southeastern China and possibly southern Japan, though it may have been introduced into Japan in very early times. It is said to have been cultivated in Japan for over 1,000 years. Cultivation spread to India and southeast Asia, the medium altitudes of the East Indies, and Australia, New Zealand and South Africa. Chinese immigrants are assumed to have carried the loquat to Hawaii.

The loquat fruits are round, oval or pyriform, pale yellow to orange in colour and are borne in loose clusters. The flesh is firm, meaty or melting, deep orange in colour, juicy and sub acidic in flavour.

Cultivars/Varieties: There are two groups of loquat cultivars – Chinese and Japanese. The Chinese type are large, pyriform and deep orange in colour, while Japanese type is smaller, light coloured and sometimes slender in form. The well-known cultivars are California Advance, Tanaka, Thales, Pyriform, Golden yellow, Improved golden yellow, Pale yellow. Other named cultivars are Improved Pale yellow, Fire Ball, Large Round, Gold Nugget, Safeda and Mammoth.

Uses

Loquat is commonly eaten as a fresh fruit. Loquat can also be processed into several products like jam, jelly and chutney. Seeds are usually taken out from the fruits, otherwise they may impart a bitter taste. The fruits are also used in gelatin desserts or as pie-filling, or are chopped and cooked as a sauce. Loquats canned in syrup are exported from Taiwan. Some people prepare spiced loquats (with cloves, cinnamon, lemon and vinegar) in glass jars. The fruit is also made into jam and, when slightly underripe, has enough pectin to make jelly.

The Loquat is a fruit of south eastern Chinese origin and it is comparable with its distant relative, the apple, in many aspects such as high sugar, acid and pectin contents. It is mostly eaten as a fresh fruit and it mixes well with other fruits in fresh fruit salads. Pies or tarts are made from firm, slightly immature fruits. A major part of total produce is used for fresh consumption, however, it can also be used for making value added products like jelly, jam, preserves, juice and squash.  Loquat syrup is used in Chinese medicine for soothing the throat like a cough drop. The flowers are regarded as having expectorant properties. It is good source of vitamin A, potassium, fiber, carbohydrates and is low in cholesterol. 

Fruit –fly : Bactrocera dorsalis :Tephritidae

The process of egg laying and ovipunctures makes the fruits deformed. Feeding of maggots in the pulp induces rotting and fruit drop.

Bark-eating caterpillar : Indarbela quadrinotata

Severe damage on loquat due to I. quadrinotata was observed during October- November in Uttar Pradesh. There are some cultivars like  Thames Pride which are less susceptible.

Genus : Eriobotrya 
Species : japonica Thunb./Lindl.
Family : Rosaceae 
Chromosome No. : 2n = 34

In Orient this beautiful and excellent fruit has failed to acquire the commercial significance which the crop deserves, further no concerted efforts have been made to improve it through selection and cultivation as has been done for many other Asiatic fruits. In contrast to major tropical and subtropical fruits which are said to be too sweet, loquat is one fruit that has subacid, sprightly flavoured fruits that match in taste and flavour to those of temperate fruits. The loquat has been in cultivation since antiquity in Japan and under present fruit culture scenario is one of the important fruits of that country

Loquat (Eriobotrya japonica) is a subtropical evergreen fruit tree belongs to family Rosaceae and subfamily Pomoideae (Lindley, 1982). It flowers in early winter and fruits ripen in mid march and may where there is scarcity of fruits. It is native to southeast China and has been cultivated in China for over 2000 years and many species occur there in wild state (Lin et al. 1999). Loquat is introduced in India under the name of Japanese medlar or Java plum. In India, it is commercially cultivated in Uttarakhand, Uttar Pradesh, Delhi, Punjab, Himachal Pradesh and hills of southern states. Among different states Uttar Pradesh occupies the first position under loquat production.

Loquat is delicious fruit known for their mild, subacid and sweet taste. It contains 60 to 70 per cent pulp depending upon the cultivar and 15–20 per cent seed. In addition to 88% water pulp is composed of 55% vitamins and 0.5% minerals, 0.6% proteins, 9.6% carbohydrates and 1.0% fibre. Loquat fruit is also rich in phenolics and carotenoids.

This theory belongs to the ‘market area’ or ‘profit maximisation’ approach and has focused on spatial variations in scales potential. August Losch was a German economist and he proposed his theory in 1939 in a book entitled Die taumliches Ordnung Derwirt’s Chaff.

He disregarded spatial variations in production costs by holding them constant, and instead depicted optimal location as occurring where the largest possible market area is monopolised – that is, where sales potential and total revenue potential are maximised. Losch sought to explain the size and shape of market areas within which a location would command the largest revenue.

Objective of the conservation of forage is to preserve as much as of the crop nutrient as possible. However, during ensilage loss of nutrients occurs. There are five sources of loss. Theses are:
 
    (a)    Field losses 
    (b)    Oxidation or respiration losses 
     (c)    Fermentation losses
    (d)    Effluent losses 
    (f)    Aerobic deterioration

11.1 Introduction

The entire amount of water that is diverted at the canal head regulator does not reach at the field for use of irrigation. Major amount of it is lost on way during its movement in the canal systems. During the passage of water from main canal to outlet at the head of the water course, water may be lost either by evaporation from the surface or by seepage through the peripheries of the channel. These losses are sometimes very high, and may go up to 50 % of the total water diverted into the main canal. Evaporation losses are low and may go to a maximum of about 7 percent.of total losses. The major loss of water in the conveyance system is the seepage loss. Seepage loss depends on the channel geometry and evaporation loss is proportional to the area of free surface. In determining the designed channel capacity, a provision of these water losses must be made. The provision for the water lost in the watercourses and in the field however, already made in the outlet discharge factor, and hence no extra provision is made on that account. However, excluding the above two losses, there is operational loss which when added to the evaporation and seepage losses, the total losses goes up the maximum 50 percent level. The operational loss includes spillage, over-toping, leakage through rodent holes, dead storage, initial infiltration and evapotranspiration from the vegetation along the watercourse. Evaporation and seepage losses of the canals are discussed below.

9.1 Introduction

The water harvested in the farm pond is a very valuable commodity. Every care should be taken so that not a single drop is wasted. The two major forms of losses in farm pond are (i) evaporation losses and (ii) seepage losses. Evaporative water loss (E_loss) and losses due to seepage are the two vital natural outflow components of unlined farm ponds. Studies conducted byGuerra et al. (1990) and Pal et al. (1994) indicated that the seepage loss from unlined ponds amounts to 45-67 per cent whereas the E_loss constitutes 30 per cent of the total out flow from the system. Water losses by evaporation and seepage were 5.3 and 9 mm day^-1, respectively amounting to 70% of total storage in the ponds (Syamsiah et al.1994).

Estimate of evaporation across the country indicates that it is as high as 2000 mm in the semi-arid tropics. Annual average value of the evaporation loss varies from 1400 to 1800 mm across major parts of the country: the value being highest in west Rajasthan, parts of Saurasthtra and Tamilnadu and lowest in coastal Mysore, Bihar plateau and east M.P. Reliable statistics reveal that about 70 M ha m of water evaporates from the water bodies and land surfaces out of the total annual precipitation of about 400 M ha m received by the country. The total evaporation losses from the water surfaces are about 5 M ha m from the total storage of 15 M ha m in the reservoirs including ponds, lakes spread all over the country (Belgaumi et al.,1997). In this section, the methods to estimate the losses like seepage and evaporation and various techniques to control them are discussed.

Lotus belongs to the Nelumbonaceae family and the genus Nelumbo. There are two species in this genus; Nelumbo nucifera Gaertn. distributed in Asia and Oceania, and Nelumbo lutea distributed in North and South America (Qichao and Xingyan, 2005). Although, the species nucifera is the most important (commercially and culturally), it is critical to describe the American species, evaluate its horticultural value and its potential as a source of genetic diversity. The American species, represented by Nelumbo lutea (Syn. N. pentapetala or Nelumbium luteum) is known as American Lotus, Water-chinquapin and Yellow Lotus (Sayre, 2004) and is native to the eastern and central portions of the US ranging from Maine to Wisconsin and in the south from Florida to Texas. It is one of the most spectacular and graceful aquatics among all the native plants of India. N. indica are found all over India and extend as far as Kashmir to Kanyakumari exhibiting enormous thermoplasticity and phenotypic diversity with a large number of racial variants with different shapes, sizes and colours. First Indian fossilised record of N. nucifera has been reported from the Pleistocene epoch of Kashmir. The presence of Nelumbo in the Tertiary period of Assam is reported on the basis of impressions of leaves and rhizomes found in the collection from Eocene bed near Damalgiri. These records confirm the evidence in support of the view that N. nucifera is indigenous to India.

Lotus has good fragrance. About seventy compounds were identified with hydrocarbons representing > 75% of the extract. 1, 4 – Dimethoxy benzene, 10, 8 – Cineole, ferpinen – 4al and linalool were important constituents characterization of the scent of lotus flower (Omata et al., 1991).

INTRODUCTION

Lotus is the foremost symbol of beauty, prosperity and fertility. According to Hinduism, within each human inhabiting the earth is spirit of sacred lotus. It represents eternity, purity and divinity and is widely used as a symbol of life, fertility, ever-renewing youth and to describe feminine beauty especially the eyes. Egyptians considered it a symbol of rebirth, since it closes in the evening and falls to the water, then reopening again in the morning, thus emulating the behavior of the sun. All lotuses are day-bloomers that open early in morning and close by mid afternoon for three successive days, with first flower closing earlier. It possesses an amazing ability to flourish in a variety of environment ranging from clear ponds to muddy marshes. The exquisite flowers with long herbaceous stalk arise from the rhizomatous stems and a flat and peculiar seedcase at its center.

Lotus, the national flower of India, has been a part of Indian culture, religion and history from ancient times. It is considered sacred not only by the Hindus of India but also by the Buddhists of China and Japan. To early Egyptians, a lotus bud or Sesen was a symbol of rebirth. Lotus is offered to Goddess Lakshmi and is considered as her symbol. Besides, lotus has found place in one of the postage stamps in India. Every year some prestigious awards are given to the distinguished personalities of the country like Padmashree, Padmabhushan, Padmavibhushan and Swarna Kamal (Golden Lotus).

Abstract: Lotus, aquatic economic flower, associated with religion, art, and culture, is native to India. Most cultivars are diploid, seed and vegetatively propagated. Lotus is cross pollinated and progeny can segregate widely for traits due to heterozygosity. Low seed set often pose significant challenge to breeders. Breeding efficiency remains unknown. Flower breeders have created new colours with interspecific hybridization including yellow, pink, white and rose colour changing to creamy yellow. Traits of interest for crop transformation include environmental adaptation to stressful condition, low seed tannin, and flowering (colour, size, timing, etc.). Genetics of characters is unknown. Future breeding and genetic studies are needed for further transformation of this crop.

Lotus being a national flower of India, is closely associated with religion and culture. It is a perennial, aquatic crop that is grown and consumed throughout Asia. The edible parts of lotus are Leaves, flowers, seeds and rhizomes, and the flowers are also used in religious ceremonies. Lotus flowers are also, used for extraction of perfumes. It is one of the oldest plants in the world Archaeologists in China found Lotus seeds with estimated ages of 5,000 years in 1972 in Yunnan Provincelagoons.

During the pre-historic period, the South India Dravidians used lotus flowers (pundarika) as their food, much earlier than the people of the Indus Valley civilization (3000-2000 BC). However, there is no evidence of lotus being present during the Indus Valley culture of the Mohenjo Daro and Harappa period in northern India. The Rigveda reference that lotus was made by the Aryans (2000-1500 BC) wherein it is also mention that lotus can be used as food. Subsequently, lotus was mentioned in the Vedas, Upanishads, Puranas, Slokas, plays and other ancient Sanskrit literature. The lotus symbol is not only mentioned in the scriptures of Hinduism but it also occurs in the Buddhist and Jainism literature.

In the Arthasastra (350-300 BC) by Kautilya, the great diplomat during the golden age of Chandra Gupta, it is recorded that one of the varieties of sandal wood possesses the fragrance of lotus. The Mughal kings were also attracted towards the beauty of lotus. While describing Agra, the Mughal king Jehangir (1605-1627 AD) in his memories Tuzuk-i-Jehangiri, mentioned a memorable scene of a tank full of exquisite red lotus flowers, the like of which he had not seen before.

Most backaches seem to begin while bending forward to pick up some object from the floor. The pain usually comes on suddenly without warning, and it may be very difficult to straighten up to a standing position again. In most cases it is felt either in the middle of the back or lower down on one side. If a spinal disc is involved, the pain may radiate down the thigh and leg along the sciatic nerve on that side. The most common cause of backache probably arises from failure to get enough exercise to keep the muscles of the back strong and healthy. Flabby muscles then produce a wobbly spine, followed by pain, spasm and misery especially if a disc is ruptured.

Low blood pressure or hypotension is far less common than hypertension or high blood pressure. Sometimes the pressure falls rapidly because of hemorrhage or loss of blood. Low blood pressure may also come on gradually because of slow bleeding in the gastrointestinal tract or through the kidneys or bladder.

Any lack of normal protein in the diet may also lower the pressure because of malnutrition or actual starvation or because of some endocrine disturbance, such as hypothyroidism. In rare cases an islet cell tumor may form in the pancreas producing an excessive amount of insulin and lowering the blood sugar level. Such patients always tend to feel tired and worn out.

Emotional problems are a far more frequent cause of low blood pressure. For instance, some people will fall into a dead faint on hearing bad news. This shock like state is probably brought on by temporary disturbance in the vasomotor system, causing the patient to collapse. To a lesser degree, prolonged disappointment and frustration may also result in a subnormal blood pressure. Relieving the chronic stress of mind may be all that is needed to bring the blood pressure back to normal. One should also add a little more protein to the diet, and be sure to take sufficient rest and exercise.

According to the Food, Drug and Cosmetic Act (1968) food is “an article that provides taste, aroma or nutritive value”. The term 'health food' is generally used to describe foods that are considered to be beneficial to health beyond a normal diet required for human nutrition. Though, the term is not precisely defined by any regulatory agencies such as the US Food and Drug Administration (FDA) however, “Health food” is sometimes used as an umbrella term encompassing natural foods, organic foods, whole foods, and sometimes dietary supplements or may also refer to functional foods. The use of foods for promoting health and relieving symptoms is as old as the practice of phyto-medicine for treating or preventing various types of illness and have been documented in Hippocratic and Vedic texts and the canons of Traditional Chinese Medicine. Therefore, “Let food be thy medicine and medicine be thy food”, quoted by Hippocrates about 2,500 years ago, is certainly the tenet of today which is receiving overwhelming interest. In the recent years, rapid urbanization, industrialization, increase in per capita income etc. in developing countries like India, have resulted in dramatic lifestyle changes leading to lifestyle related diseases like coronary heart disease, obesity, diabetes, cancer and hypertension. The transition from a traditional to modern lifestyle, consumption of diets rich in fat and calories combined with a high level of mental stress has compounded the problem further.

India produces all deciduous fruits including pome fruits (apple and pear) and stone fruits (peach, plum, apricot and cherry) in considerable quantity. These are mainly grown in the North-Western Indian States of Jammu and Kashmir (J&K), Himachal Pradesh (H.P.), Uttarakhand and in Uttar Pradesh. The North-Eastern Hills region, comprising of the States of Arunachal Pradesh, Nagaland, Meghalaya, Manipur and Sikkim also grow some of the deciduous fruits on a limited scale. The sub tropical region lies between 150 and 300 north of equator covering North Indian plains, the gangetic basin, large parts of North eastern state, western ghats, nilgiri regions etc. In this zone spring is generally frost free and chilling availability ranges from 50-500 hours. This region is not considered proper for temperate fruit growing but grows several low chilling varieties of peach, plum, pear etc. Deciduous fruits, such as peach and nectarine, require accumulated exposure to cool temperatures during winter dormancy for bud break and the resumption of normal growth the following spring. Minimum amount of accumulated cool temperature exposure needed for normal growth, which varies by cultivars, is referred to as the chilling requirement. Due to introduction and adaptation of low chilling cultivars of peach, plum and pear, they are also now being grown commercially in certain areas of the north Indian plains.

The nutritional richness and the high biological value of dairy milk have made it an important constituent of the balanced human diet. It is associated with better growth, improved status of some micronutrients, cognitive performance, motor development and activity. It is composed of a mixture of nutritive components as well as other bioactive factors such as biogenic amines, conjugated linoleic acid (CLA), with relevant physiological benefits. The consumption of dairy milk and products exert a protective action in human health and have been confirmed in preventing several chronic conditions like cardiovascular diseases (CVDs), some forms of cancer, obesity, immunomodulation and diabetes (Pereira, 2014). The chemical composition of bovine milk consists of 87% water, 4% to 5% lactose, 3% protein, 3% to 4% fat, 0.8% minerals, and 0.1% vitamins (Pereira, 2014).

1. Composition of Milk Fat

Bovine milk contains about 3.5 to 5% total lipid, existing as emulsified globules 2 to 4 μm in diameter and coated with a membrane, casein. The composition of milk fat is somewhat complex. Triglycerides constitute approximately 98% of milk fat, which is found in the milk globule, with the remainder being made up of di- and monoglycerides, phospholipids, cerebrosides, cholesterol, vitamins, tocopherols, carotene, and flavor components. Phospholipids are about 0.5 to 1% of total lipids, and sterols are 0.2 to 0.5%. These are mostly located in the milk fat globule membrane (Jensen et al., 1991). Cholesterol is the major sterol at 10 to 20 mg/dL.

Drip system has great promise for efficient utilization of available irrigation water. In our country and elsewhere in the world the scientists are unanimously agreed to adopt drip irrigation method for higher application efficiency and thereby better use of scarce irrigation water. Saksena (1993) reported water losses of only 1-2% in drip irrigation in comparison to 6-9% in sprinkler and 30-35% in surface irrigation method. However, very small area compared to other methods of irrigation so far is irrigated by drip system in our country. Up to 2000 the total area under drip irrigation was 2,59,600 ha in India (Alam & Kumar, 2000). Initial high investment for drip network and pumping system, of course, are discouraging to the most of our farmers. Sharma & Abrol (1993) mentioned that in spite of the very encouraging results and attractive subsidies offered by the Govt. of India, the adoption of the drip irrigation system has not picked up to the expected level. Along with the other reasons they pointed out the high initial cost of the system and lack of research effort on developing cost-effective design suited to local condition are responsible for non-practice of drip irrigation at a considerable scale.

Some research works has been conducted to find out low cost method of drip irrigation. Biswas (1998) developed a manually operated drip irrigation system made of bamboo mains, laterals and sub-laterals. The system and its performance are described below.

Drip Network

The main and laterals of the drip network were made of hollow bamboo pieces each of 3m lengths with 7.5cm and 4.0cm diameter respectively. The sub lateral or the emitters were the bamboo twigs of 0.25cm inside diameter and 1.05-1.10m length to suit the spacing between the plant rows. The mains and laterals were made for the required length in the field by jointing together the sections one after another (Fig. 7.1). The ends of two sections, which contact each other, were made such that one section easily gets inside the other for about 10-15cm.

Abstract

In this investigation the low dose effects of pesticides were analyzed both in vitro and in vivo in peripheral blood samples from healthy donors and also in farmers occupationally exposed to pesticides. In vitro studies were conducted to assess the toxicity caused by commonly used pesticides like monocrotophos, profenofos, chlorpyriphos, endosulfan, acephate on lymphocytes from peripheral blood samples. In almost all experiments we could determine chromosomal aberrations and DNA damage at 1/10th of LC50 dosage of the pesticides. For analyzing the in vivo effects, epidemiological studies were conducted in pesticide exposed agricultural workers. The 200 exposed volunteers suffered from fever, nausea, headache and other abnormal symptoms and visited the hospital for general health check-up. These cases were taken up for more detailed studies. Five of them (2.5%) showed decrease in RBC, haemoglobin, and increase in WBC with a large number of immature cells. These volunteers were further diagnosed as Philadelphia negative Chronic Myeloid Leukemia (CML) cases based on clinical and pathological examinations. In similar environs, about 3% of the exposed children showed signs of mental retardation and delayed milestones. It is therefore, concluded that clinical evaluations supported by occupational epidemiology could determine CML in exposed individuals (adults). At low doses we have traced the effect of pesticides at molecular level.

Low external input agriculture developed as a concept in the 1980s, gaining ground with the establishment of the Information Centre for Low External Input and Sustainable Agriculture in 1984 (Kessler and Moolhuijzen, 1994). Low external input agriculture developed as a response to the criticisms surrounding Green Revolution technology being neither sustainable nor feasible for many small-scale farmers around the world.
