The cashew nut (Anacardium occidentale L.) belongs to Anacardiaceae family which also includes the mango, pistachio and poison ivy (Nakasone and Paull, 1998). Anacardium contains 8 species all of which are native to the coastal parts of north eastern Brazil (Azam-Ali and Judge, 2001). Cashew nut tree provides food, employment, income and the wood is used for carpentry mainly in the construction of boats and ferries while other products derived from it include firewood and charcoal (Akinwale, 2000). Cashew resins are also used in the manufacture of insect repellents and natural insecticides, while different tree parts have medicinal value as they are used to cure various diseases (Cavalcante et al., 2003). The cashew tree is a sprawling broad-leafed evergreen, well adapted to poor soils and dry sandy locations, drought resistant, but grows best on well drained sandy soils with pH of 4.5 to 6.5 (Aliyu, 2004). It favours temperatures between 15 to 35°C and rainfall over 400 mm with elevation of up to 1000 m above sea level.

The emasculation and pollination in any crop depend on its floral structure and biology. Cashew is basically andromonoecious (polygamo monoecious) crop with staminate and hermaphrodite flowers appearing in the same inflorescence or panicle (Rao and Hassan 1957). The hermaphrodite/bisexual/perfect and male flowers occur intermediately in the same panicle in three or four phases viz., Male – Mixed – Male or Mixed – Male – Mixed– Male. Distinct phases depend on genotype and environmental factors. The tree shows considerable variation in the duration of different phases. The hermaphrodite flowers are bigger in size than staminate or male flowers (Damodaran et.al., 1965). Male flower always exceed the bisexual flowers. The flowers produced early in a panicle are mostly male (Rao and Hassan 1957; Damodaran et. al., 1965). Most of the perfect flowers are produced about one month after the first flower occurred in the panicle (Bhat et al., 1998).

Pruning in young tree during initial stage help to form a strong frame work for better growth and development of the tree. However, on long term way, the tree becomes huge with gigantic canopy results in to problem of majority of agronomic operation, plant protection and harvesting of crop. Top working provides an opportunity to control the growth of tree and makes the tree productive with manageable canopy, in old and senile orchards.

Top working is a technique evolved to rejuvenate the unproductive and senile cashew trees. Poor yielding trees of 5-15 years of age can be successfully rejuvenated by top working. The unproductive trees are to be headed back to a height of 1.00 m from the ground level in October-November. The stem should be sawed off to avoid stump splitting. Soon after beheading, the stumps and cut portions should be given a swabbing with carbaryl 50% WP (50 g each per litre of water) or Bordeaux paste. Sprouts emerge 30-45 days after beheading. Sprouting will be profuse in young trees. So, it is better to keep only 4-6 healthy shoots on beheaded tree spreading in all directions and similarly the sprouts which come out from ground level (most probably water shoots) also removed frequently. On 30-45 day old shoots, graft scions of high yielding varieties following soft wood grafting technique. On each tree, 4-6 grafts are to be done to ensure at least 3-4 successful grafts per tree. The best season for grafting is March-April. Thinning of the extra shoots arising from the stumps should be done to obtain better growth of the grafts. Removal of sprouts below the graft joint and removal of polyethylene strip from the graft joint should be done. Top working is simple and can be done by farmers themselves after getting proper training. The top worked trees start yielding right from the second year of top working. Early bearing can be treated as one of the best advantages of this technique. The major disadvantage associated with top working is the huge casualty of trees due to stem borer attack. Intensive care and management to ward off stem borer is essential. As such adoption of top working on a larger scale would be difficult.

In the field of agriculture/horticulture, various irrigation systems are being employed to fulfil the water requirement for better growth and development of the tree. Since, cashew is hardy plant which can sustain in rainfed conditions of warm and humid region; it has very good potential to produced higher nut yield. Of the various irrigation methods, drip irrigation system is best method in the areas where natural resources of water is limiting factor. It is well known fact that this system has many advantages.

During the first year after planting, protective irrigation is recommended at 15 days interval during winter and at 8 days interval during summer season. At each irrigation, 25 litres of water to be given per graft. The studies on mulching and irrigation were under taken with a view to determine fruit retention. It was observed that black polythene mulch with irrigation @ 60 liter of water per tree at 15 days interval showed beneficial effect on increasing fruit retention (66.15%) over control. Cashew is grown under rainfed conditions. However, supplementary irrigation during summer months, especially during January-March at fortnightly intervals @ 200 litres/plant proved to double the yield. This is evident from the research results obtained at NRC-Cashew, Puttur (Karnataka).

Maturity of Cashewnut

Cashew fruit has two parts namely cashew nut (actual fruit) and cashew apple (pseudo fruit). Development of these is not parallel. Cashew nut develops first and the pseudo fruit develops later. It takes 60 days for both the nut and the pseudo fruit to develop completely since anthesis. Development of cashew apple and nut has been studied by number of workers in different cashew varieties (Rao et al., 1962; Augustin and Unnithan, 1981; Mohan Kumar et. al., 1984; Antarkar and Joshi, 1987). According to the report, specific gravity could be considered as physical index of maturity of nut in cashew varieties of V-1, 2, 3, 4 and 5 (Antarkar and Joshi, 1987; Mohan Kumar et al., 1984). In Thailand, the nut reached maximum size in 4 weeks after fruit set, hardened in the subsequent week and declined in size by 10 per cent at harvest (Sumrit Feungehan et al., 1989). Augustin and Unnithan (1981) have reported that the growth of nut is faster during early stage of development than that of fruit. All these reports indicate that the cashew nut develops earlier than cashew apple. Changes in the composition of cashew nut and apple during development have been looked into by various workers. Hariharan et al. (1985) have reported decrease in amino acid content in kernel with increased maturity. Cashew kernel lipid, free amino acids and CNSL have been shown to increase with increased maturity. Similarly, cashew kernel phenols have been shown to decrease with maturity. Changes in the kernel sugars and starch were not uniform (Anon., 1998).

Essential oils are products of secondary metabolism and are secreted by specialized cells located in specified parts of most plants. By virtue of certain characteristic properties, they have wide spread use in perfumery, flavouring and medicine. Essential oils are variable mixtures of terpenoids. Since these oils are produced by plants, composition varies with species and variety of plant besides geography, climate and cultivation practices. Since, chemical components are highly reactive, physical and chemical environment to which oil is subjected to during the processes of its extraction, processing and storage have a great influence on final composition. Entire chain of activities from cultivation, extraction, processing, storage to packing has to be perfectly standardized and regulated to assure end product consistency. Being a valuable item of trade, this is important from the point of view of delivering desired activity as well as safety to consumer.

What is Crop?
Crop refers to plants sown and harvested by man for economic purposes. 
Cropping Seasons: There are three main seasons and two sub seasons.
1. Rainy or Kharif Season – Main characteristics of the Kharif season are 
    ·    It starts from June and spreads to September.
    ·    There is high temperature and high humidity.
    ·    More than 2/3^rd of annual rainfall is received in a year.
    ·    In the beginning, days are longer than nights while days and nights are equal when season ends. 
    ·    Important crops grown are maize, rice, sorghum, Moong, Urd, groundnut, cowpea, soybean etc. 

Introduction
Makkhan (Makhan) is an indigenous(desi) butter obtained by hand churning of dahi using wooden beater (mathani). It is traditional unsalted butter characterized by its delectable and rich flavour. It is white in colour with slightly greenish tinge and has typical soft body and a smooth grainy texture with pleasant aroma. This product has been extensively used for dietary and religious practices since vedic times. The entire quantity produced forms an intermediate product for preparation of ghee (clarified butter fat). Nearly 30% of the total milk production goes for desi butter manufacture. The average yield of the product is very low ranging from 5.5-7.0% for every 100 kg milk used for the purpose. The chemical composition of the product is variable depending upon the method of manufacture. It is difficult to achieve the uniform standard of 20% moisture in the final product due to limitations in the technique adopted for its manufacture. The non fatty solids and lactic acid are derived from the method of preparation and preservation. Higher non fatty solids in makhan indicates use of self soured milk, while a high lactic acid content indicates prolonged storage and in sanitary conditions of manufacture.

Introduction

In the recent past there has been a great deal of questioning regarding role of milk fat in cholesterol metabolism and other body functions. The enormous wave against cholesterol containing foods has damaged the image and market growth of fat rich dairy products. This trend is due to presence of saturated fats and cholesterol that are known to increase the incidence of coronary heart diseases one of the common cause of heart attack. The educated and urban society is more health conscious about the presence of cholesterol in their diets. This has led to the greater demand of cholesterol free foods. Ghee being a saturated fat and containing little amount of cholesterol, is suspected to contribute towards coronary heart diseases. However, critically surveyed scientific literature indicates that there is no evidence of any association of milk fat with increased risk of coronary heart diseases. Age old and proven Ayurvedic system of medicine has proved the usage of ghee to induce several beneficial effects on human health and used extensively for therapeutic purpose like in treatment of skin allergy, respiratory diseases, curative for ulcers and eye diseases. This suggest that ghee is a valuable form of dietary fat.

Abstract

This paper focuses on the paradigm shift that our information economy is witnessing from generic leadership to electronic leadership in a disruptive, holistic, fast changing and turbulent business environment consisting of algorithms, programs and codes, to track user movement over the digital platform. The organizations need not to choose one best way to lead in order to gain the momentum over its competitor’s. In the digital age, the organizations have started tracking user over web, his movements, his browsing information pertaining to his liking’s and disliking are been used by the leaders in order to strategize and the greatest digital minds are providing support to these organizational leaders for strategizing and flooding user with choices based on his likings. Moreover the future leadership will get more and more personalized and advanced with a conglomerate blend of cutting edge technology, leadership and strategy within the existing paraphernalia. This paper suggests a new leadership model that is the coded model, wherein the leadership gets more and more personalized based on the codes that traps user movements and his behavior over the web.

Abstract

The main reasons behind farmers for adopting organic farming practices are their concerns for the environment and about side effects of agricultural chemicals in conventional farming systems. Organic farmers find their method of farming to be profitable and personally satisfying. There is also a concern with the amount of energy used in agriculture, since many farm chemicals require energy intensive manufacturing processes that rely heavily on fossil fuels which are very limited.
This paper is an attempt to identify the current process of organic farming and initiatives to make organic farming a more profitable practice.

Abstract

This chapter highlights the importance of re-engineering the functional processes prevalent in organizations today and realigning organizational resources with policies, procedures and systems that foster innovation in the technological and managerial space and institutionalize long term sustainability of businesses in emerging market economies such as India. These economies can serve as an engine for growth in a globalized era, if the intellectual capital of these economies is utilized and enhanced with maximum possible efficiency. It is in this scenario where entrepreneurial and decision making techniques based on the knowledge management-organizational learning continuum can help in the confluence of open innovation practices and stable management expertise. Such a comprehensive strategic shift from being a financial economy to a knowledge economy needs to be supported by integration of practical actions with the untapped cognitive potential of emerging economies. This chapter shall also be useful in explaining the importance of coexistence of competition and cooperation for enhancing the viability of the organizational ecosystem in the emergent Indian economy. 

Marketing Strategy

Marketing strategy is an integral part of marketing planning. In modern day business terms, strategy refers to the matching of the activities of an organization to the environment in which it operates and to its own resource capabilities.

Definition: Marketing strategy is the complete and unbeatable plan, designed especially for attaining the marketing objectives of the firm/business unit. The marketing objectives indicate what the firm wants to achieve, the marketing strategy provides the design for achieving them. e.g. marketing objective of a business unit in the next year (2016) to achieve sales revenue of Rs. 2,000 crore and net profit will be 15 per cent on sales revenue. Then it is the job of marketing strategy to indicate how and where from this sale and profit will come, which product lines/products/brands will accomplish this task and how?

Grading and Standardization

Grading and standardization is marketing function which facilitates the movement of produce. Grading standards for commodities are laid down first & then the commodities are sorted out according to the accepted standards.
Grading means grouping the products into different classes (which posses the same characteristics) in accordance with the predetermined standards. Grading as the division of products into/commodities into classes made up of units possessing similar characteristics of size and quantity. Grading follows standardization. It is a sub function of standardization.

Product

Anything that possesses utility is described as goods. A product is both what a seller sell and what a buyer has to buy. 

According to Phillip Kotler: A product is anything that can be offered in a market for attention acquisition, use or consumption that might satisfy a want or need. It includes physical objects, services, persons, places, organisation and ideas.

According to Stanton: A product is a set of tangible and intangible attributes, including packaging, colour, price, manufacturer’s prestige, retailer prestige and services which the buyer may accept as offering satisfaction or wants or needs.

Sales Management

According to American marketing Association “Sales management is the planning, direction and control of personal selling, including recruiting, selecting, equipping, assigning, routing, supervising, paying and motivating as these tasks apply to the personal sales force.”

It has been repeatedly proving that Science& Technology that is close and in harmony with nature is proving winner in the long run. If the past 60 years led to the Green Revolution in agriculture which often became Greed Revolution, the next 60 year should be the emergence of love for nature, diversity and Sustainable Green Revolution. The two goals – Sustainability and Productivity are inter-related.

It is also said that the main difference between the past and today is that our problems are truly global. We are also aware that globally and nationally the rich-poor divide is growing and though world produces enough food, nearly 800 million people remain food insecure. Among 8 millennium goals, eradication of poverty and hunger and environmental sustainability are perhaps the most prominent and complimentary.

Higher Farm Production with Lower Input Cost

There is a great need to reduce the input costs and at the same time improve the farm productivity in a sustainable manner. A model has been worked out based on a number of field demonstration studies in different parts of India, Africa and Far Eastern countries. A model in which input cost can be reduced by nearly 20 percent and at the same time the crop production can be enhanced upto 20 percent is possible and can be a boon to farmers in most parts of the world. This is the model, which can be easily adopted in an evolutionary way. As suggested by Jonathan Foley (BOX – 1), use of high-tech, precision farming systems, as well as approaches borrows from organic farming, we can boost farm productivity substantially.

"Where is your Dhoti, Dr. Mehta ?” Dr. Varghese Kurien surprised me as I entered his office at IRMA (Institute of Rural Management Anand). That was April 2000, soon after I had taken over as the Vice Chancellor of the erstwhile Gujarat Agricultural University (GAU) and had decided to call on him during my visit to the Anand Campus. (At that time GAU was the largest University in the Asia with four main campuses – Dantiwada, Anand, Junagadh and Navsari and about 65 experimental farms / stations spreaded all over).

In contrast to the traditional universities, agricultural universities have been entrusted with the Herculean task of technology dissemination at the grass root level such that the package of practices evolved by the agricultural scientists should reach out the end-users, viz. farmers , for adopting in the field, with consequent increment in the farm productivity and farmer’s income.

This unique mandate has been assigned to agricultural universities on the pattern of land grant colleges of the United States. Such vision and trust, envisaged by Pandit Jawaharlal Nehru and his devout lieutenants, herald creation of state agricultural universities (SAUs) in the early 1960s. The key role played by SAUs in the first green revolution and agricultural human resources development have been regarded as the milestones in the history of India post-independence, that made the country self-sufficient in food production and, in turn, to self reliance in milk, vegetables, fruits and inland fish production.

Care and treatment of animals is possible by the combined efforts of all the stake holders of animals shared by the owners, consumers and veterinarians. Although, veterinary services are available throughout the country, involving different stakeholders including veterinarian, there is an entrenched lack of empathy and a profound disconnect among stakeholders when it comes to identifying with the pain and discomfort of animals. 
Veterinarians participate in two ways in animal welfare and animal ethics. One is the role of the veterinarian as an individual member of a profession. The other is the collective role of the profession, as expressed by the professional bodies.

Animal Welfare Board of India was started under the stewardship of Late Smt. Rukmini Devi Arundale, well known humanitarian. The Animal Welfare Board of India is a statutory advisory body on Animal Welfare Laws and promotes animal welfare in the country. The board established in 1962 under Section 4 to 10 of the Prevention of Cruelty to Animals Act, 1960 (No. 59 of 1960).  The primary sources of funding of the AWBI are grants from the Government of India. However, contributions, subscriptions, bequests and gifts will also be encouraged.

The process of civilization and materialist life style has forced man to make laws which govern or rule the conduct of the people of society or community. In the earlier days the relation of human and animal was interdependent and mutual. Now a days man has become self-centered and ignorant of his surroundings. This has led to cruelty on the animals in many circumstances. Therefore, in pursuit of prevention of the cruelty to animals following laws, regulations have made by the government.

Sheep and goat rearing in India continues to be traditional even today. This sector is primarily in the hands of poor, landless or small and marginal farmers who raise their animals on natural vegetation, stubbles and supplement tree lopping. The productivity of sheep in India is relatively low with an average body weight gain of 20 to 50 g/day. The major causes for the low productivity are inadequate grazing resources, tropical heat and disease incidences and a lack of awareness about improved management practices.

1 Broilers

The broilers are also called young meat chickens; generally attend a body weight of 2 kg at 35-38 days of age with a feed conversion of 1.5-1.8. This improvement in growth is equivalent to reduction of market age by one day per year. This fast growth is possible due to intense feeding good quality feed & growth promoters in less space. However, this type of rearing has challenges many welfare issues in broiler farming.

Various indicators like range of behavioural, physiological, pathological and carcass-quality parameters can be used to assess the welfare of animals. Whenever, animals undergo painful handling or any other managerial operation, they are likely to face short-term stress. In this condition an increased physiological responses, behavioural responses, injury or mortality are most commonly used; however, some animals which are kept in improper housing with less floor space may cause chronic stress leading to increased disease incidence and suppression of normal development. Therefore, the following techniques can be used to assess the animal welfare at farm level in any given situation.

4.1 Introduction

More and more industrial applications require self cleaned surfaces, water repellent, anti-dirt pickup and many other specific surface requirements. Introduction of nanotechnology has changed the coating scenario drastically. Hard, anti-scratch, hydrophobic coatings are achieved by the addition of small amounts of nano-pigments which help in creating hydrophobic surface. It is also possible to grow certain nano-fibers which on chemical treatment give surfaces which can either attract water or repel it. It is also possible now to create self healing coatings which can repair surface once they are damaged by scratch. Capacitance coupler pads have been devised to reach those corroding areas which are not covered by other corrosion protection methods. Stringent requirements of many modern industrial application resulted in developing coatings which can give special surface properties such as high hardness, scratch resistance, hydrophobicity, anti-dirt pickup etc.  This brief article presents a few new researches which provide one or more special properties to the surface.

MMPs are a family of zinc-containing, calcium-dependent endopeptidases secreted by various cell types and implicated in a wide range of physiological events (e.g. trophoblast invasion, development, endometrial remodeling, ovulation, angiogenesis, wound healing, bone resorption and cell migration) as well as in pathological processes. Matrix metalloproteinase (MMPs) and their tissue inhibitors (timps) have been strongly implicated in the pathogenesis of many types of human cancer. Expression levels for the most relevant MMPS are confirmed by reverse-transcriptase polymerase chain reaction (RT-PCR). The activities of MMPs are significantly higher in malignant tissues than benign canine tumours.

Tumours of mammary gland are the most common tumours of female dog representing approximately 30-50% of all tumours in bitch. Chemotherapy is a kind of treatment that uses drugs to attack cancer cells. The importance of chemotherapy has been emphasized that survival could be prolonged after chemotherapy in cancer patients.

Considering immunosuppressive nature of mammary tumours, the use of immunotherapy to prevent cyto-toxicity of cancer drugs, further metastasis and prolong survival period in canines. “ImmuPlus” (Indian Herbs) is a type of polyherbal ayurvedic product containing extracts of Ocimum sanctum, Withania somnifera, Emblica officinale and Tinospora cordifolia.

Cancer cryosurgery began in England during 1850s, when James Arnott used local application of salt solutions containing crushed ice to treat advanced cancers in accessible sites, such as breast and the uterine cervix. Since then, landmark advances in chemistry, physics, material science, and biology have culminated in the sophisticated cryosurgical devices currently in use.
 
Cryosurgery is defined as a method that uses the local application of extreme cold to destroy abnormal or diseased tissue, with the possibility of the maintenance of normal adjacent tissue. Normal tissue can be maintained because the extension of the ice ball can be controlled. Tissue temperature should reach -20^o C or below. Attempts should be taken to kill all tissues in the target with minimal damage to surrounding tissues. There is a variable response of tissues to cryotherapy based on density, vascularity and the water content of the tissue, temperature and size of the cryoprobe, spray rate, rate of freeze, rate of thaw and number of freeze and thaw cycles. It is ideal to have quick freeze and slow thaw for maximum benefit. The extent of freezing should be closely monitored, with either temperature monitoring probes or by visual inspection and palpation of frozen area and this is more advantageous in case of relatively small lesions.

Introduction

Agriculture is highly dependent on environment, and it’s very difficult to get favourable climate and other conditions for optimum crop growth and development as per crop need. Open field conditions are having a high direct affect of the prevailing weather conditions on crop growth, and also on population dynamics of viruses, fungus, bacteria, insects, etc. With time crops has adopted themselves to specific seasons, but the fast changing climatic conditions happening across the globe has changed the climatic characteristics of a season. This has resulted in untimely rains, high temperature fluctuations and changes in other abiotic and biotic factors in geographically varied locations where it was not supposed to be earlier based on various geographical factors deciding the climatic conditions of that area. Therefore, there is need to develop suitable technologies to sustain these challenges. How to address these issues, can we manipulate the climatic conditions or can we provide protection to the crops against climatic fluctuations and various other related stresses.

Introduction

The green revolution technologies involving the greater use of synthetic agrochemicals with adoption of nutrient responsive, high yielding varieties of crops have boosted the production output. However, this increase in production has slowed down and in some cases there are indications of decline in growth of productivity and production. Environmental and health problems associated with agriculture. These questions have given rise to a process of serious thinking to safeguard the environment and the quality produce.

Introduction

Increasing concern about climate change and global warming has created immense awareness among society about green house gas and its reduction. Irrespective of the geographical location, population density and economic development of any region, there is a huge scope for addressing the green house gas emission. Cities have a key role to play in the global agenda for addressing the challenge of climate change. Today, approximately half of the world’s population lives in cities; by 2050, that proportion will probably have increased to two-thirds. India has the highest rate of change of the urban population and will remain above 2% annually for the next three decades. At this rate, an estimated 854 million people will live in Indian cities by 2050.

In the recent years it has been increasingly realized that only increase in physical production of crops no longer guarantees the smooth development of agriculture at both the farm and the national economy levels unless and until it is linked with efficient system of marketing. As such, now a day in planning for agricultural development specially in developing economies marketing system had drawn much more attention than customarily assigned to it. Efficient marketing of agricultural commodities in general and fruits crops in particular plays an important role in safeguarding the interest of producer as well as consumer.

Introduction

The National Commission on Agriculture defined agricultural marketing as a process which starts with a decision to produce a saleable farm commodity and it involves all aspects of market structure of system, both functional and institutional, based on technical and economic considerations and includes pre and post- harvest operations, assembling, grading, storage, transportation and distribution. The Indian council of Agricultural Research defined involvement of three important functions, namely (a) assembling (concentration) (b) preparation for consumption (processing) and (c) distribution.

The first use of rubber was by the Olmecs, who centuries later passed on the knowledge of natural latex from the Hevea tree in 1600 BC to the ancient Mayans. They boiled the harvested latex to make a ball for a Mesoamerican ballgame.

1.1 Introduction

Pomegranate (Punica granatum L.) is a well-known table fruit of tropical and subtropical regions of the world. The Romans received it from Carthage, hence the name of the genus Punica. Some botanists place it in the family Lythraceae, of the peculiar type of fruit, called as balausta, most authorities make it the only genus in the family Punicaceae. It belongs to genera Punica and family Punicaceae (Chatterjee & Randhawa, 1952; Joshi, 1956). It is a small tree, measuring less than 4 m when cultivated, although it can reach 7 m in the wild. Recent research findings corroborate traditional use of pomegranate as a medical remedy as all parts of this plant have several bioactive metabolites (Holland et al. 2009). Consequently, its demand has increased tremendously not only in the western world but also in other parts of the globe.

O horizon: A soil layer dominated by organic materials occurring at the surface of the soil. 

Oblique Aerial Photographs: An oblique photographis one which has been taken with the optical axis of the camera intentionally tilted from perpendicular position obliquely. The degree of tiltfrom the perpendicular further classifies oblique photographs into high oblique photograph and low oblique photograph. A high oblique photograph is one which is taken with the optical axis of the camera making an angle >30^° with the vertical axis and which shows the apparent horizon on the photograph.

Wasteland: Land not capable of producing materials or services of values.

Water available : The amount of water, plants can extract from unit volume of soil. It is mainly derived from capillary water and corresponds roughly to the water held by the soil between the limits of field moisture capacity and the wilting co-efficient.

Water balance: i) The distribution of water in space, and over time, within a system. Where plants are growing on land this means considering rainfall (and also interception loss, stemflow and throughfall), drainage, evapotranspiration, runoff and soil water storage. ii) Balance of input and output of water within a given defined hydrological area such as a basin or a lake, taking into account net changes of storage.

Multiple Choice Questions

Physiological or abiotic disorders are mainly caused by changing environmental conditions such as temperature, moisture, unbalanced soil nutrients, inadequate or excess of certain soil minerals, extremes of soil pH and poor drainage. The distinction between physiological or abiotic disorders from other disorders is that they are not caused by living organisms (viruses, bacteria, fungi, insects, etc.), but they are the result of abiotic situations (inanimate) i.e. their agents are non-living in nature which causes deviation from normal growth. They results in physical or chemical changes in a plant which is far away from what is normal and is generally caused by an external factor. Non-infectious disorders in some cases are easy to identify, but others are difficult or even impossible to recognize. Most of them are non reversible once they have occurred. For the identification of physiological disorders it is important that one must know that:

The word banana is derived from the Arabic word “banan,” which means finger and it is known as “the fruit of the wise”. In the middle ages, the banana was thought to be the “forbidden fruit of paradise”. Bananas are the most popular fruit in the world. Members of the genus Musa are considered to be derived from the wild species Musa acuminata (AA) and Musa balbisiana (BB). It is not a tree, but a perennial herb the leaves of which are usually grouped together, forming a trunk-like structure called pseudostem. The origin of bananas is believed to be Malaysia or India. Bananas are a very important commodity for developing countries, with a clear dual nature as they are at the same time a major staple commodity and a fundamental export commodity. There are almost 1000 varieties of bananas in the world with lot of commercially recommended cultivars. The most commonly known banana is the Cavendish variety, which is usually produced for export markets.

Coconuts are the fruit of the coconut palm, botanically known as Cocos nucifera, where nucifera means “nut-bearing”. The fruit-bearing palms are native to Malaysia and southern Asia. The coconut has been regarded as ‘man’s most useful tree’, ‘mankind’s greatest provider in the tropics’, ‘one of the nature’s greatest gifts to man’, ‘tree of life’, ‘tree of abundance’, ‘tree of plenty’ and the ‘tree of heaven’ or ‘Kalpa Vriksha’ in India. In Sanskrit Kalpa Vriksha means “tree which gives all that is necessary for living” because nearly all parts of the tree can be used in some manner or another. The Indian state of Kerala is known as the land of coconuts. The name derives from “Kera” (the coconut tree) and “Alam” (place or earth). It has great antiquity in India which is also evident from the fact that the part of Malabar Coast, extending from South Kanara to Cape Comorin, is known as Keralam meaning the land of coconut.

Phoenix dactylifera commonly known as the true date palm, is a palm in the genus Phoenix, cultivated for its edible sweet fruits. The fruit’s English name as well as the Latin species name dactylifera, both come from the Greek word for “finger,” Daktulos, because of the fruit’s elongated shape. The date palm is believed to have originated in the lands around the Persian Gulf. Date palms are said to thrive with their “feet in water and heads in the sun” because they need plenty of ground water but high heat and arid weather to produce fruit. Therefore, date palms grow best in hot and arid climates.
