Introduction

It is found growing wild in the sub-tropical and tropical parts of India. The edible part of annona is the areoles. It has about 120 species, five of them having pomological significance, and four of the five species are important in commerce. Custard apples are cultivated mainly in Maharashtra, Madhya Pradesh, Gujarat, Karnataka, Andhra Pradesh, Uttar Pradesh, Bihar, Assam, and Orissa.

The animals are mostly social ones and prefer living in herds. In each species there are certain rules for group survival, cohesion, defence and also for propagation. The basic patterns of male sexual behaviour appear to be innate in nature. Kids of both sexes are very often seen exhibiting sexual display during play and mounting is seen most commonly. In females the sexual receptivity is restricted to few hours or days near the estrous phase of the estrous cycle, while in males the sexual receptivity is grossly permanent. The physiological signals for arousal of sexual motivations originate from gonadal steroid balance. However, the secretion of gonadal steroids is not permanent. In males the androgen secretion is in the form of several peaks within 24 hours reflecting the pulsatile release of pituitary gonadotropins. However, the total amount of androgen in males is almost constant practically for day to day. In females the secretions of estrogens are restricted only during few days (follicular phase) of the estrous cycle.

a. Financing the dairy enterprise

Dairy rearing provides triple benefits of income, employment and nutritional security to the society and is important source of subsidiary income to small/marginal farmers and agricultural laborers. Finance is a prerequisite and of paramount importance for setting up of a dairy enterprise whether a dairy farming unit for milk production, sheep or goat unit/piggery unit, dairy/poultry processing unit etc. Decisions about credit are often most important judgments that people in the agricultural industry must make. These decisions often determine whether individuals operating in input, production, processing, and services based dairy enterprise would succeed in making profit.

ABSTRACT

In Kerala, apart from cultivated sesame species (Sesamum indicum L.) three wild species were identified viz. Sesamum malabaricum, Sesamum mulayanum and Sesamum radiatum. An investigation was carried out to determine the intensity of arbuscular mycorrhizal fungal colonization in cultivated and wild species of sesame. The percentage of arbuscular mycorrhizal fungal infection in roots of different sesame species were found to be variable. The highest percentage of root colonization of arbuscular mycorrhial fungi was found in wild species S. malabaricum, which promotes tolerance to the plant under drought stress conditions.

Soil pollution indicates the presence in the soil of any chemical or substance out of place and/or present at an abnormally higher concentration so as to adversely affect any non-targeted organism. Soil pollution often cannot be visually perceived or directly assessed, thus rendering it a latent danger. The Status of the World’s Soil Resources Report identified soil pollution as one of the main soil threats affecting global soils and the ecosystems services provided by them. Concerns about soil pollution are growing in every region. Recently, the United Nations Environmental Assembly (UNEA-3) adopted a resolution calling for accelerated actions and collaboration to address and manage soil pollution. This consensus, achieved by more than 170 countries, is a clear sign of the global relevance of soil pollution and of the willingness of these countries to develop concrete solutions to address the causes and impacts of this major threat.

29.1. Sources of Soil Pollution

The main anthropogenic sources of soil pollution are the chemicals used in or produced as byproducts of industrial activities, domestic, livestock and municipal wastes (including wastewater), agrochemicals, and petroleum- derived products. These chemicals are released to the environment accidentally, for example from oil spills or leaching from landfills, or intentionally, as is the case with the use of fertilizers and pesticides, irrigation with untreated wastewater, or land application of sewage sludge. Soil pollution also results from atmospheric deposition from smelting, transportation, pesticide applications and combustion of many substances as well as radionuclide fallouts from atmospheric weapons testing and nuclear accidents. New concerns are being raised about emerging pollutants such as pharmaceuticals, endocrine disruptors, hormones and toxins, among others, and biological pollutants, such as micropollutants in soils, which include bacteria and viruses.

Inability to go to sleep or to get sleep for a period insufficient for the needs of an individual is known as insomnia. Chronic inability to sleep.

None of us can do without sleep. An infant sleeps 14 to 18 hours a day. This period is slowly reduced. An adult may be happy with 7 to 8 hours of sleep every night. There are people who require 5 hours or even 4 hours of sleep in 24 hours.

Sleep has a definite purpose and that is why all mammals sleep. Lack of sleep apparently does not cause any physical harm. But anyone who gets less than his normal sleep experiences a decrease of efficiency and concentration.

Hygienic collection of semen is an integral part of the artificial insemination process. Semen collection implies mounting a teaser doe or a dummy. Therefore, proper semen collection deserves the utmost attention. Sexual efficiency is measured by the percentage or successful semen collections among attempted collections. When males are allowed to female teaser, the male exhibits characteristic behavioural symptoms such as sniffing, nudging or mounting at that time it is necessary for the operator to attempt an approach. This approach has to be done quietly to avoid a fear reflex in the male. The male, even if it mounts the female, deviation of its penis into the receptacle. Under the circumstances, the operator should not more from his squatting position, so that the male does not associate the two events. The animal generally comes back by itself to attempt remounting the female and will serve the artificial vagina. The operator should also stimulate the male by voice.

Basella (Basella alba and B.rubra) is a common leafy vegetable grown in practically all countries of Tropical Asia and Africa (Syn.Malabar spinach, Ceylon spinach, India spinach, Vine spinach, etc.). The flavour of this green vegetable is mild and similar to spinach. Basella alba is widely grown in Europe, with the red stemmed varieties in particular being popular as ornamentals. It’s a popular green in Asian, Indian, and even African cuisine, albeit the soft veining shoots are preferred above the leaves in Africa. The Chinese names for Malabar spinach literally translate to “flowing water vegetable.”

Different types of Romanowsky type of stains are used for staining the cytological smears. It will give excellent cytoplasmic and nuclear details and it also stains bacteria. The following stains are commonly used. e.g., Wrights, Giemsa, Leishman, Wright-Giemsa, May-Grunwald-Giemsa, Leishman-Giemsa, Haematoxylin and Eosin, Diffquik stains, Trichrome stains, Papanicolaou or Sano modification.

Staining Methods

Leishman-Giemsa

• Cover the smear with LG stain for a minute
• Dilute with tap water/Distilled water/ phosphate buffered saline pH 6.87.2
• Allow to stain for about 20 min
• Wash in water

To most of us Prof. Swaminathan was a great Scientist, humanist and true global leader. I am blessed to have been associated with Prof. Swaminathan. From a brilliant scholar to a visionary global leader, he had continuously moved to higher and higher level of achievements. The nine decades of his life can be divided in 4 phases – Brilliant & dreamy student, devoted scientist and Science Manager, a visionary and missionary solving the hunger problem and a global citizen and humanist. The vision and drive had taken him to extraordinary heights – Like Maharshi Patanjali has said in Yoga Sutra– “When you are inspired by some great purpose, some extraordinary vision, all your thoughts break their bond. Your mind transcends limitations, your consciousness expands in every direction and you find yourself in a new, great wonderful world.” Among many things, I also recollect his inspiration when I was planning GSFC Science Foundation and later the activities of Gujarat Agricultural University.

INTRODUCTION

The National Rural Employment Guarantee Act 2005(NREGA) was brought into force by the Union Government in February 2006 which was renamed on 2^nd October 2009 as MGNREGA i.e. Mahatma Gandhi National Rural Employment Guarantee Act. It is the first nation-wide employment scheme that guarantees employment legally to India’s rural population. According to the Union Rural Development Ministry’s figures, more than 1.36 crore people of the country’s total population have been given jobs under the Act. It guarantees 100 days of unskilled jobs per rural household. This is meant to regenerate the rural natural resource base, which in turn, will result in sustainable livelihoods for residents. It is with this background the present article has been planned with the specific objectives to explore the extent of awareness about NREGA among the target group of the Act. Ray (2008) told that, director, Development, Allahabad University included NREGA in the curriculum of rural sociology and has suggested that seminar; workshops and university publications can be used for awareness generation. UNIFEM Workshop (2009) concluded that, in case of Kerala, Kudumbashree and Panchayat have been very vigilant in spreading awareness about NREGA through radio, poster, television, notice board on gram Sabhas, etc.

For seed storage in the gene banks, the seed stored should have high quality which is greatly affected by seed handling during collection. The details on these issues have been given by Smith (1995).  In terms of seed storage characteristics seeds are of following 3 steps.

Gale : Wind of force 8 or above blowing continuously and damaging trees, houses etc.

General Circulation : The average general distribution of wind in motion on the Earth. This general circulation includes the scientific description of atmospheric dynamics not only statistically but also from the point of view of physics. The global wind systems like westerlies, trades, etc., are the examples of general circulation.

General Circulation Model : At present, there are different models in vogue, to explain the general circulation of the atmosphere. If the general circulation is modelled in a three dimensional procedure, then it is known as a general circulation model.

Geopotential : The potential energy per unit mass of a body due to the earth’s gravitational field referred to an arbitrary zero.

Soils play a vital role in the health of ecosystems in the world. Soils connect with air, water, rocks and organisms and are responsible for a multitude of functions in the global ecosystem services. These functions include providing habitat for most living things, air composition and quality, temperature regulation, carbon and nutrient cycling, water cycling and quality, and natural waste recycling. Mankind cannot survive without these soil functions.

30.1. Habitat

Soils are the environment in which plants grow. They provide heat, nutrients and water to nurture plants to maturity. These plants, together with other plants and organisms, create ecosystems. These plants then provide valuable habitat and food sources for animals, bacteria and other things. Ecosystems depend on the soil and soils determine the nature and kind of ecosystems.

Worms and other intestinal parasites are found in every part of the world. They are more common in tropical and sub tropical areas and are more common during the rainy season. Most of these worms and parasites enter in the human body either through the mouth or through the skin of the feet.

Round worms, are the giant worms present in the intestines that cause the disease kwon as ascariasis. It is found in almost all the countries. These worms are off-white in colour, are long and thick and are most frequently seen in children. Eggs produced by them are passed in stools. When children play in the soil contaminated with the eggs, particularly children living under unhygienic conditions easily transfer them to the mouth via dirty fingers.

Roundworm eggs may remain alive in the soil for many months. There is always greater danger of contamination where human wastes are used in fertilizing vegetables. Great care must be taken to be sure all foods are thoroughly cleansed and sterilized by cooking before being used.

Maize is an ideal forage crop grown throughout the country. It is quick growing, high yielding and provides palatable and nutritious forage which can be fed at any stage of growth without any risk to animals. Maize produces good quality herbaceous fodder with high digestibility. On an average, it contains 9-10% crude protein, 60-64% neutral detergent fibre, 38-41% acid detergent fibre, 28-30% cellulose and 23-25% hemi cellulose on dry matter basis when harvested at milk to early-dough stage. It can be fed as green or dry and makes excellent silage.

Introduction

Pitaya also known as Dragon Fruit is a superfruit indigenous to central and South America that is grown all over the world. It has a faint, sweet taste much like an earthy watermelon. It’s a fast growing crop and the plant as can have produced for more than seven to eight years. The fruit of this plant having red skin covered with large scale and white or pinkflesh contains some black seeds. It can be used in jams, ice creams, jelly production, fruit juice, and wine. This fruit is famous in Thailand, Vietnam, Israel and Sri Lanka. This fruit cultivation is excellent in regions where less rainfall is expected. This fruit plant is treated as an ornamental plant as well as a fruit producing plant. Dragon fruit contains 73.9 kcal, 1 g protein, 0 g fat, 0.5 g fiber, 23 g carbohydrates, 23 g sugar, calcium 30 mg. 10.9 mg sodium and 1.79 mg vitamin C. Dragon fruit is consumed as a fresh fruit or can be used in jams, ice cream, jelly production, fruit juice and wine. This fruit is also used in face packs.

Bathua is an old plant that is also known as lamb’s quarters or cheel bhaji. Its scientific name is Chenopodium album. In India, the plant leaves are boiled and consumed like other green vegetables. Chenopodium is a weedy annual plant with a high growth rate. This is completely natural and a distinguishing feature of the plant. When the leaves mature, the powdery residue disappears. Look for younger leaves if eating raw. Otherwise, look for sturdy, robust leaves that aren’t wilted.

Botany and taxonomy Chenopodium album is a weedy annual plant belonging to the Chenopodium genus.
