Astro-meteorology is considered as one of the branches of Astronomy along with Astrophysics, Astrobiology and Astrometry. Astronomy is the science that deals with the material universe beyond the earth’s atmosphere. It studies the nature and constitution of Celestial (heavenly) bodies and the laws which govern them including the effect they produce upon one another. It seeks to unravel the probable past history of heavenly bodies and their development. There exists a confusion between the branches of Astronomy viz., Astrophysics and Astro-meteorology with the term Astrology. Astrophysics uses principles and laws of physics to explain how Celestial bodies form and function or in other words it will help to ascertain the nature of the astronomical objects, rather than their positions or motions in space. However, the Astrology and Astro-meteorology are the subjects deal in future prediction and often considered as pseudo-science which uses position and movement of stars and planets for that purpose. Astrology links these to predict the human behaviour, while that of Astro-meteorology links the same to predict the future weather.

From ancient days, these predictions are based on one’s wisdom and knowledge in astronomy and often these astrologers are astronomers who keenly watch the stars and planets movement and guide their rulers and farmers with their guesstimates. Till date it is being lore, mainly passed to followers of this group and the methodology is not documented clearly and properly. There are many incidences of falsified predictions of astrology as reported by many reviewers elsewhere and we are not discussing the same here, owing to our interest in weather prediction i.e., astro-meteorology only. However, we have to recognize the works of the ancient astrologers who helped in developing the astronomical science.

Basically, there are two approaches in astrology viz., geocentric and heliocentric as used by the practitioner of astrology worldwide. As the name implies the Geocentric astrology is based on the calculation of planetary position as seen by the observer from the earth and thus earth is centre, while Heliocentric astrology bases its interpretation upon position within solar system with reference to the sun as centre. Though in true sense, the sun is the centre, the effect of motion as manifest on the earth is the basis of most astrological interpretation. Hence, vast majority of astrologers employs the geocentric calculations of the planetary positions for their predictions.

1. GERMPLASM

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

1.1. Conservation methods

1.1.1. In situ conservation

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

Absolute advantage : This is the simplest yardstick of economic performance. If one person, firm or country can produce more of something with the same amount of effort and resources, they have an absolute advantage over other producers. Being the best at something does not mean that doing that thing is the best way to use your scarce economic resources. The question of what to specialise in—and how to maximize the benefits from international trade—is best decided according to comparative advantage. Both absolute and comparative advantage may change significantly over time.

Access to Health Care : 1) The degree to which individuals are inhibited or facilitated in their ability to gain entry to and to receive care and services from the health care system. Factors influencing this ability include geographic, architectural, transportation, and financial considerations, among others. 2) Entry to the health care system is dependent on the wants, resources, and needs that individuals bring to the care-seeking process. Ability to obtain wanted or needed services may be influenced by many factors, including travel distance, waiting time, available financial resources, and availability of a regular source of care.

Acquisition cost : The purchase cost of a drug to an agency, person or institution.

Adaptive expectations : A theory of how people form their views about the future that assumes they do so using past trends and the errors in their own earlier predictions. Contrast with rational expectations.

Apple is the pomaceous fruit (Malus domestica) in the rose family (Rosaceae). It is one of the most widely cultivated tree fruits, and the most widely known of the many members of genus Malus that are used by humans.

The apple originated in South-West Asia which includes Asia Minor, the Caucasus, Soviet Central Asia, Himalayan India and Pakistan. It is grown extensively in the temperate region. The major apple growing countries are Australia, Argentina, Brazil, China, Canada, Denmark, Egypt, France, Gemany, USA, India, etc. In India states of Jammu and Kashmir, Himachal Pradesh and mountanous region of Uttar Pradesh are the major apple producers.

Cultivars/Varieties: The apple varieties are divided into three groups based on their maturing periods. The early season varieties grown in the states of Himachal Pradesh, Jammu & Kashmir and Uttranchal are: Tydeman’s Early(P), Irish Peach, Early Shanburry(P), Michael Molies, Benoni Fenny, Benoni Delicious, Schlomit Starkrimson, and Chaubattia Princess. The Mid season varieties are: American Mother, Red Delicious, Richared Razakwar, Starking Delicious, Vance Delicious, Jonathan(P), McIntosh(P), Top Red Lord Lam, Cox’s Orange Pippin(P), Cortland bourne(P), Red Chief, Red Gold(P), Golden Delicious(P), Oregon Spur, Queen,s Apple, Redspur, Rome Beauty, Scarlet Siberian. The late season varieties are: Golden Delicious(P), King’s Pippin, Rymer, Yellow Newton(P), American Apirouge, Buckingham(P), Winter Banana, Kerry Pippin, Granny Smith(P), Sunhari Chamure, Golden Delicious(P), Red Delicious, Ambri Baldwin, and Yellow Newton(P).

Backwardation : When a commodity is valued more highly in a spot market (that is, when it is for delivery today) than in a futures market (for delivery at some point in the future). Normally, interest costs mean that futures prices are higher than spot prices, unless the markets expect the price of the commodity to fall over time, perhaps because there is a temporary bottleneck in supply.

Balance of payments : The total of all the money coming into a country from abroad less all of the money going out of the country during the same period. This is usually broken down into the current account and the capital account. The current account includes : *visible trade (known as merchandise trade in the United States), which is the value of exports and imports of physical goods; *invisible trade, which is receipts and payments for services, such as banking or advertising, and other intangible goods, such as copyrights, as well as cross-border dividend and interest payments; *private transfers, such as money sent home by expatriate workers; official transfers, such as international aid. The capital account includes : *long-term capital flows, such as money invested in foreign firms, and profits made by selling those investments and bringing the money home; *short-term capital flows, such as money invested in foreign currencies by international speculators, and funds moved around the world for business purposes by multinational companies. These short-term flows can lead to sharp movements in exchange rates, which bear little relation to what currencies should be worth judging by fundamental measures of value such as purchasing power parity. As bills must be paid, ultimately a country’s accounts must balance (although because real life is never that neat a balancing item is usually inserted to cover up the inconsistencies).

Balanced budget : When total public-sector spending equals total government income during the same period from taxes and charges for public services. Politicians in some countries, such as the United States, have argued that government should be required to run a balanced budget in order to have sound public finances. However, there is no economic reason why public borrowing need necessarily be bad. For instance, if the debt is used to invest in things that will increase the growth rate of the economy—infrastructure, say, or education—it may be justified. It may also make more economic sense to try to balance the budget on average over an entire economic cycle, with public-sector deficits boosting the economy during recession and surpluses stopping it overheating during booms, than to balance it every year.

Bael (Aegle marmelos, L.) belongs to the family Rutaceae and is an important indigenous fruit of India known since 2000-820 BC. Bael is considered to be native to India and is grown all over the country. It is also seen in south east Asian countries like Sri Lanka, Pakistan, Bangladesh, Burma, Indonesia and Thailand. It is a hardy plant and can be grown even on marginal soils.

The leaves are trifoliate and aromatic. The leaves of the tree are used in religious offerings. The fruit is usually globose, grey or yellowish with small hard aromatic rind. The pulp is thick mucilaginous, orange yellow in colour with sweet scented aroma. The importance of bael fruit lies in its curative properties. It is used in Ayurveda for its medicinal properties.

There are no recognized or improved varieties of bael with a standard name. It usually goes with the name of locality or region it is grown in. Ayodhya, Etawah, Faizabad Local, Gonda Selection, Kagzi Bael, Kagzi Kalan, Mirzapuri, Darogaji, Ojha, Rampuri Azamati, Khamaria, Deoria Large, Gonda-1 and NB-5 are a few to name.

Uses

Bael fruits cut in half, or the soft types broken open, and the pulp, dressed with palm sugar, eaten for breakfast, as is a common practice in Indonesia. The pulp is often processed as nectar or “squash” (diluted nectar). A popular drink (called “sherbet” in India) is made by beating the seeded pulp together with milk and sugar. A beverage is also made by combining bael fruit pulp with that of tamarind. These drinks are consumed perhaps less as food or refreshment than for their medicinal effects.

Mature but still unripe fruits are made into jam, with the addition of citric acid. The pulp is also converted into marmalade or sirup, likewise for both food and therapeutic use, the marmalade being eaten at breakfast by those convalescing from diarrhea and dysentery. A firm jelly is made from the pulp alone, or, better still, combined with guava to modify the astringent flavor. The pulp is also pickled. The young leaves and shoots are eaten as a vegetable in Thailand and used to season food in Indonesia. They are said to reduce the appetite. An infusion of the flowers is a cooling drink. (Morton, 1987).

Introduction

During transition period and lactation, the high-producing dairy cows undergo a period of extensive tissue catabolism because of negative nutrient balance. Homeorrhetic mechanism at this stage ensures that nutrients are partitioned to favour the growth of fetus prepartum and meet the demand of nutrients in early lactation. Simultaneously the homeostasis secures survival of the animal body functions. However, a decline in feed intake in transition period leads to metabolic disturbances and low milk production in early lactation. The postpartum negative nutrient balance impairs immune and reproductive functions in dairy cows and buffaloes. The increased demand for nutrients and decreased dry matter intake results in low circulating glucose and insulin levels and elevated non-esterified fatty acids (NEFA) and ketone bodies postpartum. The energetic status of a cow or buffalo modulates the secretion of hormones that play key roles in growth of ovarian follicles, ovulation, corpus luteum (CL) formation, and oocyte competence. The NEBAL not only limits milk production potential but also has a detrimental effect on immune cells. Negative nutrient balance is associated with changes in the pattern of ovarian follicle growth and oocyte quality and alteration in endocrines. In addition, cows under negative nutrient balance have extended periods of anovulation. These changes could be minimized by supplementing energy rich supplements like prilled fat or any bypass fat preparations.

Effective marketing channels are essential for ensuring the timely availability and accessibility of quality fish feed across India’s diverse aquaculture systems. The distribution network typically involves a multi-tiered structure, including manufacturers, distributors, wholesalers, retailers, and direct-to-farm supply, connecting producers with end-users. The Indian fish feed landscape comprises both large-scale national manufacturers and numerous small and medium-sized regional producers. Large companies often rely on a structured distribution model involving regional distributors and wholesalers who then supply products to retailers, particularly in rural and semi-urban areas. Retailers serve as key intermediaries, not only selling feed but also advising farmers on feeding techniques and aquaculture practices. In several regions, cooperatives, Farmer Producer Organizations (FPOs), and aquaculture clusters help streamline feed supply by utilizing collective bargaining to obtain better prices and ensure quality consistency. Direct sales from manufacturers to large commercial farms are also gaining traction, particularly in intensive and semiintensive aquaculture settings. The rise of digital tools has further enhanced reach—ecommerce platforms and mobile ordering systems are now offering convenient and timely delivery solutions, even to remote locations.

Hard currency : Money you can trust. A hard currency is expected to retain its value, or even benefit from appreciation, against softer currencies. This makes it a popular choice for people involved in international transactions. The dollar, d-mark, sterling and the Swiss franc each became a hard currency, if only some of the time, during the 20th century.

Hawala : An ancient system of moving money based on trust. It predates western bank practices. Although it is now more associated with the Middle East, a version of hawala existed in China in the second half of the Tang dynasty (618-907), known as fei qian, or flying money. In hawala, no money moves physically between locations; nowadays it is transferred by means of a telephone call or fax between dealers in different countries. No legal contracts are involved, and recipients are given only a code number or simple token, such as a low-value banknote torn in half, to prove that money is due. Over time, transactions in opposite directions cancel each other out, so physical movement is minimised. Trust is the only capital that the dealers have. With it, the users of hawala have a worldwide money-transmission service that is cheap, fast and free of bureaucracy. From a government’s point of view, however, informal money networks are threatening, since they lie outside official channels that are regulated and taxed. They fear they are used by criminals, including terrorists. Although this is probably true, by far the main users of hawala networks are overseas workers, who do not trust official money transfer methods or cannot afford them, remitting earnings to their families.

The aggregate of data forming a subject of investigation is known as population. Example, All the crop plants grown in a plot; all the fruit plants in an orchard, etc. The population may be:

1. Finite: No. of observations are definite. e.g., number of farms in a village, no. of house in a locality, no. of trees in an orchard are all finite population.
2. Infinite: Number of observation are indefinite e.g., (a) Number of insects in a region, number of grasses in a field etc. are all infinite population.

The Population may be:

1. hypothetical or theoretical

   Hypothetical population consists of unit that has no physical existence. This population exists only in imagination. For example, Result of tossing coin, throwing die,

2. Existent or real population consists of units that are physically present. This population actually exists. For example, Number of employees in a factory, Number of farms in a village.

Introduction

Water resource is imperative for the survival of all life-forms on planet earth and defines the limits of sustainable development, without any substitute. Only 2.5% of all water on the earth is freshwater, and of that, around 0.5% is accessible through ground or surface water supplies. The increasing world population, industrialization and climate change is putting additional pressure on water resources. This is also true for livestock sector. As per prediction equations, the requirement of water for livestock will rise from 2.3 billion m³ in 2000 to 2.8 billion m³in 2025 and 3.2 billion m³ in 2050 (Hedge, 2012).

The balance between humanity's demands and the quantity available is already precarious (Karin et al, 2002). Additionally, climate change poses a serious threat to water resources as the climate system and the hydrological cycles are intimately linked, and any variability in climate affects the hydrological cycle. The World Bank report on the water and climate change inter-linkages also reiterated that climate change could profoundly alter future patterns of both water availability and use, thereby increasing levels of water stress and insecurity, both at the global scale and in sectors that depend on water (Alavian et al., 2009).

Mercury, a heavy metal, is present vi. Various forms and is well known for its toxic effects especially on human health. Mercury occurs naturally vin the environment through volcanic eruptions, weathering of rocks and forest fires. It can be observed in soil, water and the atmosphere. Human activities such as mining, industrial processes (eg. Coal Combustion, chor alkali production) and improper disposal of mercury containing products contribute to environmental contamination. Mercury can be absorbed through inhalation ingestion or skin contact. Once absorbed, mercury distributes throughout the body, crossing g the blood brain barrier and placenta. Inorganic mercury is partly metabolized to organic forms, such as methyl mercury, by micro organisms in environment. Mercury is excreted via Urine and feces. Mercury disrupts neuronal function by interfering with neurotransmitter signalling pathways, cognitive function, motor coordination and sensory perception Mercury accumulates in the kidneys, causing tubular necrosis. Proteinuria and renal failure. Clinical signs and symptoms are tremors memory loss, nausea, vomiting, hypertension and chest pain. Diagnosis is based on medical history, physical examination, blood, Urine, hair tests and neuro imaging techniques namely MRI or CT scans. Treatment is based on chelation therapy. Finally it is concluded that understanding the sources, toxico kinetics, toxico dynamics clinical manifestations and treatment options is critical for effective management and prevention of mercury toxicity.

Labour economics : The aspects of economics concerned with the supply and demand for labor. This includes factors affecting the participation rate, wage bargaining and organized labor, training, hours and conditions of work, practices concerning hiring, redundancy, labor turnover, migration and the age of retirement.

Labour intensive : A production process that involves comparatively large amounts of labour; the opposite of capital intensive.

Labour market flexibility : A flexible labour market is one in which it is easy and inexpensive for firms to vary the amount of labour they use, including by changing the hours worked by each employee and by changing the number of employees. This often means minimal regulation of the terms of employment (no minimum wage, say) and weak (or no) trade unions. Such flexibility is characterised by its opponents as giving firms all the power, allowing them to fire employees at a moment’s notice and leaving workers feeling insecure.

Labour theory of value : The notion that the value of any good or service depends on how much labour it uses up. First suggested by adam smith, it took a central place in the philosophy of karl marx. Some neo-classical economists disagreed with this theory, arguing that the price of something was independent of how much labour went into producing it and was instead determined solely by supply and demand.

Introduction

Castor (Ricinnus communis L.) is an important non-edible oilseed crop and occupies an important place in the country’s vegetable oil economy. The crop is mostly confined to Gujarat, Andhra Pradesh and Rajasthan. Although other states like Tamil Nadu, Karnataka, Orissa, Maharashtra, parts of Madhya Pradesh, Bihar and Chhattisgarh cultivate castor, their contribution to either area or production is limited. Presently, castor is grown over an area of 8.7 lakh hectares with a production of 11.7 lakh tonnes and productivity of 1352 kg/ha in the country (2008-09). Castor oil finds application in manufacture of a wide range of ever expanding industrial products such as nylon fibres, jet-engine lubricants, hydraulic fluids, soaps, varnishes, paints, medicines and a host of similar other products. Castor cake is used as manure and also as nematicide. Gujarat and Andhra Pradesh put together contribute to 68.5% of the total castor area and 80% of the total castor production in the country. The crop has been cultivated under resource-rich irrigated conditions in Gujarat with very high productivity (1963 kg/ha), while in Andhra Pradesh, the crop has been cultivated under rainfed and poor resource management conditions, with very low productivity (509kg/ha).

NAIRU : The non-accelerating-inflation rate of unemployment (see natural rate rate of natureal rate of unemployment).

Nash equilibrium : An important concept in game theory, a Nash equilibrium occurs when each player is pursuing their best possible strategy in the full knowledge of the strategies of all other players. Once a Nash equilibrium is reached, nobody has any incentive to change their strategy. It is named after John Nash, a mathematician and Nobel prize-winning economist.

Nation building : Creating a country that works out of one that does not - because the old order has collapsed (as in the former Soviet Union), or been destroyed by war (Iraq), or never really functioned in the first place (Afghanistan). To transform a failed country can involve establishing order through the rule of law and creating legitimate government and other effective social institutions, as well as a credible currency and a functioning market economy. Nation building is rarely easy, and often fiendishly difficult, especially where there are deep ethnic, religious or political divisions in the population or the country has no history of ever functioning effectively. Outside expertise, such as from the world bank, and money (as in, most famouly, the marshall plan) can help, but they are no guarantee of success.

Introduction

Water is one of the most complex natural resources demanding a comprehensive understanding of its inherent features in occurrence and distribution for an integrated planning aimed at optimum development for agriculture, health, industry, power, etc. The well being and development of our society is dependent on the availability of water. An increase in groundwater development and utilization for industries and urban water supply has created improper disposal of liquid waste. Defective well constructions, sewage and waste disposal in man made lakes within city, open quarries with water and failure to seal the abandoned wells in city area have provided possible openings for downward movement of polluted water into subsurface formations without undergoing the process of natural filtration.

2.1 Clean Cultivation

This type of cultivation is extensively followed in India. It involves regular ploughing of the land followed by removal of weeds. Tilling the orchard soil regularly provides a weed free environment in the orchard. Traditional tillage with the spade or hoe involves shallow cultivation and partial burying of weeds. Use of animals for ploughing reduces the labour cost but some superficial tree roots get damaged in ploughing. Tractor drawn tool can be used during initial years when the orchard trees are not fully grown. Branches hanging low, spreading in the inter-row spaces hinders the movements of the tractor even in widely spaced rows at maturity in most of the orchards. Under such situations small power tillers can be used. Tillage controls weeds partly through burying weeds and partly through exposing underground parts of weeds to desiccation. The land around the trunk must be cleaned separately with the help of spade as it is difficult to operate a power implement in the vicinity of the trunk. This is very instrumental in saving soil moisture. It has immense effects on the soil properties. Cleaning removes the protecting layer of vegetation and exposes the soil surface to weathering, and thus reduces the frequency of additions of organic matter to soil. Cultivation physically disturbs soil, mixing upper and lower layers. In this management system, the interspace between the trees is kept clean by tillage by removal of weeds. Clean cultivation by tillage influences the soil aggregate size and stability, porosity and pore size distribution, and the development of sub-surface layers of high bulk density (hard pans). The first change that occurs with tillage is the disruption of established soil pore continuity (Chan and Mead 1989). Organic carbon and nitrogen decline to a new equilibrium value depending on tillage intensity, cropping system and climate.

Stored-product insects damage grains, cereals, pulses and other commodities, causing quantitative losses and deterioration in food quality and nutritional value. Climate change influences temperature and humidity within storage environments, directly affecting insect development, reproduction, survival and population growth. Warmer conditions may shorten life cycles, increase the number of generations and expand the distribution of important storage pests. Poor storage structures and inadequate pest management further increase these risks, particularly in developing countries. This chapter examines the influence of changing climatic conditions on stored-product pests and emphasizes improved storage design, monitoring, sanitation and climate-adaptive management practices for protecting stored food and maintaining food security.
