Introduction

Food demand is rising at an unprecedented rate as the world's population continues to rise. Meeting this rising demand is a significant challenge that requires innovative and sustainable solutions. While traditional agriculture has long been the backbone of food production, alternative methods such as aquaculture have gained recognition for their vital contribution to global food security. The projected global population of over 9 billion by 2050 presents a significant challenge in meeting the nutritional demands of an ever-expanding populace. Seafood represents a crucial source of animal protein, essential nutrients, and omega-3 fatty acids, making it a dietary staple for millions of individuals globally, particularly in coastal regions and developing nations.

American Ecologist Whittaker (1969) proposed the five kingdom system of classification. In his ‘Five Kingdom System’, he added three more kingdoms in to Linnean model of two kingdom system. These were: Monera, Protista and Fungi. Whittaker succeeded to overcome the difficulties as well as demerits of two, three and four kingdom systems and to represent the living organisms according to the evolutionary relationships among themselves. He also defined the kingdoms by a number of special characteristics such as whether the organisms possessed a true nucleus or not. Whittaker’s five kingdom system of classification is based on (a) mode of nutrition (b) cell structure and complexity (c) phylogenetic relationship (d) body organization and (e) reproduction.

The large branches within the Animal Kingdom evolutionary tree are ‘phyla’ (the singular being ‘phylum’). ‘Animal phyla’ outlines thirty three phyla, although there are still disputes and disagreements concerning how many phyla are needed to classify the less well-known species. The most easily recognised are Porifera, Cnidaria, Arthropoda, Nematoda, Annelida, Mollusca, Platyhelminthes, Echinodermata, and Chordata. Animal phyla each comprise a branch of the evolutionary tree and these branches are always connected to other branches.

In India, some of the major horticultural crops productivity is affected by major problems. Some of these have been overcomed by certain control measures strategies. However, a few of them are long lasting and have attained the status of national problems. These are mango malformation, alternate/biennial bearing, spongy tissue in mango, bunchy top of banana, guava wilt, citrus decline, rootwilt of coconut and yellow leaf disease of arecanut.

Mango malformation: Mango malformation was reported for the first time from Darbhanga, Bihar. The disease is more prevalent in northwest than northeast and south India. This disorder is widespread in flowers and vegetative shoots.Three types of symptoms are mainly observed. These are bunchy top phase, floral malformation and vegetative malformation. Bunchy top phase is observed in nursery, bunching of thickened small shoots, bearing small rudimental leaves. Shoots remain short and stunted giving a bunchy top appearance. In vegetative malformation, excessive vegetative branches of limited growth are observed in seedlings. 

Introduction

 India, situated between the latitude of 08004’ and 37006’ N and longitudes of

68007’ to 97025’ E, has a geographical area of 329 Mha. Physiographically, it

can be divided into three broad regions, viz., Peninsula (a triangular Plateau in

the Deccan and South of the Vindhyas), Mountain region of the Himalalayas

(Extra-Penninsula), and the Indo-Gangetic Plain separating these two regions.

Geologically, a great part of the Penninsula is occupied by the gneiss, schists

and other rocks of diverse nature. Red soils (Alfisols) generally predominate in

this region. The western and central parts predominate in basaltic rock having

Black cotton soils of different thickness (Vertisols, Inceptisols). The mountain

region shows the development of marine sediments of all ages, especially, in

north of the Himalayas. The vast Indo-Gangetic and other plains of Pleistocene

origin are composed of alluvium of the great river systems flowing in this

region. The alluvial soils of this region depend on the age of alluvia and degree

of development.

Climatically, India shows three distinct seasons:

 i) Cool and mainly dry winters from November to February

ii) Hot and mainly dry summers from March to June

iii) Monsoon rainy season from mid-June to September.

Camphor plant is valued for presence of camphor in its wood and leaves. Camphor is chiefly a pharmaceutical product though it is used in preparation of artificial essential oils like lavender and lavendin.  It is used as incense and in balms of various kinds.  It is employed as a masking agent in perfumery and sometimes used to achieve lift in perfume blends. Redistilled brown oil is used directly in soap perfumes for a masking effect. Oil is a source of safrole which is a starting material for production of various perfumery chemicals. In 13th century, Marco Polo noted that camphor oil was highly valued by Chinese as a medicine, scent, and embalming fluid.

Black pepper, christened as “King of spices” and “Black gold” is the most important and the most widely used spice in the world occupying a position that is supreme and unique. It was the lure of Indian pepper that brought the western world to Indian sub continent.

The black pepper of commerce is the dried mature fruit of the tropical perennial climbing plant Piper nigrum. Pepper originated in the tropical evergreen forests of the Western Ghats. The Malabar coast of India was the centre of pepper trade from time immemorial. Black pepper was essentially a minor forest produce in the past, people collected it from forests where it abundened. Domestication of pepper appears to be a much later event. The recorded history shows that Arabs, followed by the Portuguese, the Dutch and the British traders took pepper to all over the world and spread its use and cultivation. Initially black pepper was taken from the Malabar coast to the Indonesian islands, then it spread to various Pacific islands, South East Asian countries and later to tropical Africa and America. Currently, pepper is grown in about 26 countries, major being India, Indonesia, Brazil, Malaysia and Srilanka. In India, pepper is grown mainly in Kerala, Karnataka, Tamil Nadu and to a little extent in Goa, Orissa, Assam and Andaman group of islands. Kerala is the original home of pepper. This state accounts for 95% of country’s area and production.

India, the land of oldest civilization known through out the world for its vibrant cultures, faiths, lifestyle, traditions, rituals etc. which are interwoven with each other since time immemoral. Here people of different ethnic groups live together who speak different languages and dialects according to their religion and choice. Altogether, 68 million inhabitants belonging to 227 ethnic groups, comprising of 573 tribal communities exists in different part of the country. These people constitute 8.08% of the total population of India (1991 Census of India) and speaks <750 dialects that can be classified into one of the following three language families: Austro-Asiatic (AA), Dravidian (DR), and Tibeto-Burman (TB). When come to think of different tribal community’s inhabiting India, they can be easily divided into six major racial lineages i.e. - Negroid, Mongoloid, Proto-Australoid/ Austrics, Mediterranean or Dravidian, West Brachycephals and Nordic Aryans

Fertilizer recommendations are generally made on the basis of soil test. Recommendations of fertilizer for top-dressing are best made on tissue testing.

SOIL TEST

A number of approaches have been adopted to increase the precision of soil-test values in making fertilizer recommendations. Four most important ones are discussed.

Low-Medium-High Approach

Making fertilizer recommendations based on soil test for a nutrient involves conducting a large number of ?eld experiments on soils similar to those which are intended for making recommendations. For an individual nutrient (say P for example) experiments are conducted with graded doses of P on a crop for which the fertilizer recommendations are to be made. Thus, agronomic experiments are to be conducted for each crop on each kind of soil. The response curve can then be divided into three sections: a, low soil-test value and high response to fertilizer zone; b, medium soil-test value and medium response to fertilizer zone; and c, high soil-test values and no response to fertilizer zone. In India, this was done

Introduction

It is common that after a rocket start, entrepreneur’s lack the motivation to scale up business and eventually fails to succeed in the market. There are many factors that may lead to such failures or even success stories, the most important being the entrepreneurial skills and traits that enable business to sustain in the competitive world.

What makes an entrepreneur competent in running a business? According to Fisher and Koch (2008), ‘Entrepreneurs are born; the advantage that they derive by birth being the natural advantage. However, we have changed our mindset now-a-days, that it is possible to nurture (make) an entrepreneur; the connotation points out that, right kind of education and training can inspire people with capacities to become motivated to be an entrepreneur.

In this chapter, our focus will be on identifying the entrepreneurial capacities in oneself, after reviewing the essential characteristics and traits that an entrepreneur should possess. Also we try to put forward a framework for entrepreneurship, fitting into the canvas of a food based entrepreneur.

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.

Morphological characteristics

Straight bole, longitudinally fissured bark, imparipinnate and elliptic leaves, fragrant flowers in huge panicles, and winged, flat pods distinguish Pterocarpus species in the field. The tree can grow up to 30 metres tall and 2.5 metres wide, with a straight and clean bole. The bark is scaly, tough, and fissured longitudinally. Leaflets are five to seven in number, 8–13 cm long, oblong or elliptic in shape, or rotund in shape, with 15–20 pairs of lateral veins. Kino-gum is a fragrant, brittle, almost black oleo-resin obtained from tree trunks that is angular and glistering and comes in minute flakes..

Floral characteristics

Yellow flowers bloom in panicles that are 1–5 cm long and fragrant. Flat, orbicular, winged pods with a diameter of up to 5 cm. Seeds range from one to three in number, are bony, and have a convex form. Flowering starts in November, and fruits lasts until March.

Distribution

The tree can be found in central and peninsular India, primarily in dry mixed deciduous tropical forests in Gujarat and Madhya Pradesh, as well as sub-Himalayan tracts, at elevations of up to 1000 metres. Natural populations have plummeted, and there are hardly any fragile young saplings in the forest. Due to a lack of autogenic reproduction, this species is endangered.

A very common condition caused by Malassezia pachydermatis in dogs. It is also caused by predisposing allergic skin disease. It occurs in ventral neck, ventral abdomen, axilla, face, pinnae, feet and forelegs. Tape impression smear will reveal numerous yeasts.

Okra

Genetic Resources

Okra [Abelmoschus esculentus (L) Monch.] s a crop of the tropical and subtropical owland regions of Africa, Asia, America and warmer temperate region of the Mediterranean. It is believed to be originated from tropical Asia or may have been existing in Africa and India as polyphylatic species. A. tuberculatus, one of the ancestors of okra occuring in India, has nine wild taxa, of which A. esculentus is popularly grown for pod production. The main region of cultivation and diversity of okra in India, Sri Lanka, Pakistan, Nepal and Bangladesh, are represented by various local cultivars of A. esculentus and A. moschatus (Table1).

Indifferent stage: Primordia are present for both sexes (gonads and mesonephric and paramesonephric ducts), although genetic sex is determined at fertilization.

Gonads : are structuarally indistinguishable prospective testis and ovaries. The first sign of gonadal development is a swelling called the gonadal ridge on the medial side of the middle part of the mesonephros. It enlarges due to arrival of primary germ cells. Cells of mesonephric tubules invade the ridge to form clusters and besides surround germ cells resulting in gonadal cords.

The primordial germ cells of these gonads arise from the endodermal cells of the yolk sac. These migrate to the gonadal ridge through the dorsal mesentry. Migration of primordial germ cells from the yolk sac endoderm into the gonadal ridges initiates testicular (if SRY gene is present) or ovarian development. The primordial germ cells form the sex cells, called gonadal blastema. The somatic blastema (non-germ cell) forms the other parenchymal elements of the gonads. The germ cells are capable of amoeboid-like movement.

The male genital organs (Fig. 4-6 C) comprise the two testicles (where the male gametes are produced) with their coverings and appendages; the epididymis (which stores and transports the gametes); the ductus deferens (the ducts of the testicles); the seminal vesicles, prostate and bulbourethral glands (accessory sex glands); the urethra and the penis (the organ of copulation).

Testicles (Testes)

The testicles are the essential male gonads. They produce male gametes, the spermatozoa and the endocrine secretion which influences the development and maintainance of masculine characteristics. The testicles are paired compound tubular glands situated in the scrotum below the inguinal canals suspended by spermatic cords. Each testicle is about 15 cm long and about 6.5 to 7.5 cm in diameter. Their long axis is vertical. The left testicle is more often slightly larger and lower in position than the right testicle. In such conditions the scrotum appears asymmetrical. Each testicle is slightly compressed from side to side and presents two surfaces, two borders and two extremities. The lateral surface is convex and smooth and is covered by the tunica vaginalis propria. The medial surface is slightly flattened due to its contact with the septum scroti. The cranial border is convex and it is free and hence is called the free border. The caudal border is nearly straight and is attached to the epididymis and hence is called the attached border or the epididymal border. The dorsal and ventral extremities are blunt and rounded.

Structure: The gland is compound tubular in structure. It is covered externally by peritoneum, the tunica vaginalis propria which is very closely attached to the underlined tissue. Underneath the peritoneum is the capsule of the testicle called the tunica albuginea because of its white colour. Numerous trabeculae extend from the capsule into the organ forming the supporting tissue for the seminiferous tubules and providing a pathway for vessels. The axial strand of connective tissue extending almost the entire length of the gland is the mediastinum testes. Radiating from the mediastinum are the lobes of yellowish

The male reproductive system consists of a pair of testes that produce sperm (or spermatozoa), ducts that transport the sperm to the penis and glands that add secretions to the sperm to make semen. The adult mammalian testis performs two important functions, spermatogenesis and male sex hormone production. It is an organ structurally designed to produce the haploid male gametes from diploid postnatal germ-line stem cells, i.e. type A spermatogonia.

Male sterility refers to a condition in which pollen is either absent or non functional or unable to produce functionally viable pollen in flowering plants. Since it was first reported by Kolreuter as early in 1763 that anther abortion occurs naturally in some plant species or in their inter specific crosses, its occurrence was observed in several species. In the 19th century, Gartner (1844) and Herbert (1847) reported the occasional recurrence of anthers rudimentariness or abortion in many ornamental and vegetable crops in normal populations. During the early 20th century, a large number of species were shown to possess male sterility, for example, Suturela hortensis, Lathyrus odoratus, Merculalis annua, Solanum tuberosum, Vitis vinifera, Linnum usitatissimum, Zea mays, Antirrhinum majus, Prunus persicaer and Rubus idaeus. Following the rediscovery of Mendel’s Laws of Inheritance, study of the genetic main basis of inheritance of male sterility attracted the attention of several workers. The main impetus for the study of inheritance of male sterility came from the elucidation of heterosis in maize by G. H. Shull, in 1908 and its exploitation through the use of male sterility by Jones and Clark (1943). The male sterility based scheme of hybrid seed production in corn opened up a new era for the hybrid corn industry as it could overcome the necessity of detasseling of female (parent) lines in the hybrid seed production process.

The male sterility may arise due to malformation of male sex organs, lack of normal anther sac, and inability of anthers to release mature pollens, lack of development of normal microspore.

Male sterility is a situation where the male reproductive parts of a plant are either absent, aborted, or non-functional; and therefore, they fail to participate in the process of natural sexual reproduction. This situation generally arises due to some developmental defect that occurs at any stage of microsporogenesis (process of development or release of pollen grains) in the plants. Since male sterility is the manifestation of abnormal growth and development and can occur at any point of time, the action of genes controlling male sterility is also be variable and inconsistent across the genotypes. Based on the type of malfunctioning of androecium, the male sterility systems have been classified as structural (absence or deformity of anthers), sporogenous (defective microsporogenesis), and functional (failure of mature pollen to germinate). In addition, on the basis of genetic control mechanism of the male sterility, it has also been classified as genetic, cytoplasmic, and cytoplasmic nuclear (or genetic) male sterility. With respect to utilization of male sterility in crop breeding, it is essential that individuals with altered male fertility keep their female fertility intact. The fertilization of such plants takes place with pollen grains from other plant that is transferred with the help of external agencies such as wind, insects, or human beings.

Male sterility is a condition in plants whereby the anthers or pollen are nonfunctional. The condition may manifest most commonly as absence of pollen or extreme scarcity of pollen, severe malformation or absence of flowers or stamens, or failure of pollen to dehisce. Just like self-incompatibility, male sterility enforces cross-pollination. Similarly, it can be exploited as a tool to eliminate the need for emasculation and for hybrid seed production on commercial scale in field and vegetable crops. There are three basic kinds of male sterility based on the origin of the abnormality related to functional pollen grain.

Abstract

The landslides that swallowed the whole of Malin village, Maharashtra on the early morning hours of 30 July, 2014 is one of the major disasters, next only to Kedarnath episode in the recent years. Consequently, the Department of Science and Technology, New Delhi, constituted an expert committee comprising the authors of the article which made a visit and took the on the spot assessment of the disaster. Their observations show that the area is covered by the Deccan basalts, which are layered with compact and vesicular basalts; fractured and jointed basalts due to tectonics and the cooling of the basalts; and have also undergone extensive geomorphic evolution. Due to such geologic/geomorphic setting, the flow layered basaltic hillock in which Malin is located is naturally benched, which is further being leveled for the agriculture purposes. The deforestation, leveling of the hills, excessive usage of water for irrigation and the lack of drainages outlet in such benched and leveled slopes have assigned high degree of landslide vulnerability to the area. Over this, when torrential rainfall occurred in the last week of July, the landslide was triggered. On the basis such inferences, some mitigation measures have been evolved after the visit.

7.1. Okra or Bhindi (Abelmoschus esculentus L.)

Okra (Bhindi) is a member of Malvaceae family, earlier known as Hibiscus esculentus, and is an annual vegetable crop grown from seeds in tropical and subtropical parts of the world. Okra, also known as “lady finger” or “gumbo”, is a highly nutritious green edible pod vegetable. Botanically, this perennial flowering plant belongs to the mallow family but is grown as an annual. It is named scientifically as Abelmoschus esculentus. Okra originated in tropical and subtropical Africa and India is suggested to be the secondary centre of origin. There are four species under Abelmoschus genus which includes both cultivated and wild forms. They are A. esculentus, A. manihot, A. caillei and A. moschatus. In India, Okra is widely cultivated in states of Andhra Pradesh, West Bengal, Orissa, Bihar Uttar Pradesh, Karnataka, Assam West Bengal, Orissa, Gujarat and Bihar.

Cultivars/Varieties: Okra varieties differ in growth habit, height of plant, presence of purple pigmentation and ridges on fruit. The popular varieties under cultivation in different parts of the country are Arka Abhay, Arka Anamika, Azad Kranti, Co 1, MDU1, Gujarat Bhindi 1, Harbhajan Bhindi, Hisar Unnat, Parbhani Kranti, Perkins Long Green, Punjab 7, Punjab 8, Punjab Padmini, Pusa A 4, Pusa Makhmali, Pusa Sawani, Red Bhindi, TN Hybrid 8 and Varsha Uphar. Besides, a number of hybride from many private sector agencies/seed companies are marketed. Of these, Varsha, Vijay, Adhunik, Panchali, Hybrid No. 6,7 and 8, Nath Sobha, Supriya, Sungro 35, Aroh 1, - 2, -3, -9 and are more popular.

Uses

Different parts of the plant are used for different purposes. Abelmoschus moschatus Medik. Leaves and seeds are considered as valuable traditional medicine. Abelmoschus moschatus is also called ‘musk okra’ a medicinal plant belonging the same family. The leaves and new shoots of this plant is also used as vegetable. The aromatic seeds of this plant are aphrodisiac, ophthalmic, cardio tonic, antispasmodic and used in the treatment of and intestinal complaints and anxiety.

Thomas Robert Malthus enunciated his views about population in his famous book, Essay on the Principle of Population as it affects the Future Improvement of Society, published in 1798. Malthus revolted against the prevailing optimism shared by his father and Godwin that a perfect state could be attained if human restraints could be removed.

Malthus’ objection was that the pressure of increasing population on the food supply would destroy perfection and there would be misery in the world. Malthus was severely criticised for his pessimistic views which led him to travel on the continent of Europe to gather data in support of his thesis. He incorporated his researches in the second edition of his Essay published in 1803.

The Malthusian theory of population is the most well-known theory on population in economics. Malthus pointed out that an accelerated increase in population would outweigh the increase in food production. This would have an adverse impact on the development of an economy. The Malthusian theory explains the relationship between the growth in food supply and in population. It states that population increase faster than food supply and if unchecked leads to vice or misery. This theory is explained in the following propositions

ABSTRACT

Malting is the process accompanied by restricted sprouting of cereals in humid atmosphere along with controlled set of conditions. It is a process of soaking, germination and drying that causes changes to the microstructure of grains. Malting causes changes in functional and nutritive value of grains. Malting results in increase in protein content, mineral availability, in vitro protein digestibility, oil absorption capacity, water absorption capacity, water solubility index and fall in level of antinutritional factors, viscosity and bulk density. The malting conditions are significantly affected by varietal difference, maturity of grains and structural composition. Therefore, optimum malting conditions should be determined for grains in order to avail the health and nutrition benefits.

A family of about 244 genera and 4,225 species, Malvaceae are distributed widely in tropical and temperate regions. About 22 genera and 125 species of Malvaceae have so far been reported from India. Some of the larger
genera, along with their common names and/or number of reported species in parenthesis, include Hibiscus (rose mallow, 300), Sida (200), Abutilon (Indian mallow, 100), Alcea (60), Malva (mallow, 40), Lavatera (25), Gossypium (cotton, 20) and Althaea (12). The family is recognized by Hibiscus rosasinensis (Rose of China) because of its beautiful large flowers and hundreds of its known cultivated varieties.
Hibiscus commonly called as ‘Chinese hibiscus’ or ‘Rose of China’ or ‘Hawaiian hibiscus’ or ‘Blacking plant’ or ‘Shoe flower’ is a flowering plant of hot and warm climate, and hence, known as ‘Queen of Tropics’. Florida is the
prominent hibiscus growing centre of the world. The commercial species have wide variety of uses including fibers, food, medicinal and ornamental, either as a potted plant, fence or hedge plant or as a landscape shrub. Ethno medicinal value of hibiscus is documented

Key Points

• In diary animals, the health of the mammary gland (udder) is paramount.

• Any udder or teat disease state has a direct impact on milk output.

• Common udder/teet affections include: abscess, mammary gland hematomas, udder cleft dermatitis, udder edema, intramammary hemorrhage, teat damage, ulcerative mammillitis, udder dermatitis, and more.

Introduction

Mammary gland (udder) health is a crucial factor in animals used for production. The state of the udder determines the dairy industry's economics. The output of dairy animals is directly impacted by any udder ailment. Due to selection, breeding, genetic engineering, and animal management, animals under production pressure are more susceptible to a variety of diseases. More safety measures should be implemented in order to shield the udder from illness-causing factors. The many udder and teat affections and their therapeutic management are briefly discussed in this chapter.

Lactation is the process of milk secretion by the mammary gland. Lactation is the final phase of the complete reproductive cycle of mammals. Newborns of most species are dependent on maternal milk during the neonatal period. Lactation is therefore essential for survival of the species.

Cancer has gained considerable relevance in animals now-a-days owing to the increased awareness among people towards animal sufferings and pain. The diagnosis and management of neoplasm, therefore, represent the major challenges faced by a veterinary oncologist. Mammary gland tumours are among the most common canine neoplasm, but the vast majority of these tumours occur in intact female dogs. In canines, mammary gland tumours that occur in males ranges from 0-2.7% (average < 1%). Sex hormones plays a vital role for the occurrence of mammary gland tumours. The p53 gene over expression is an independent factor for indicator of worse prognosis in canine mammary gland tumours. The p53 may be useful prognostic markers for evaluating malignancy in canine mammary gland tumours. There is a strong positive correlation between expression of cyclooxygenase-2 (Cox-2) and grade of malignancy in the tumours. Increased Cox-2 expressions are linearly related in the canine mammary gland tumours and are also related to worse prognosis and shorter overall survival. Canine mammary gland malignant tumours have the highest values of Cox-2 expression. Matrix metalloproteinase (MMPs) are a family of zinc and calcium-dependent proteolytic enzymes that degrade macromolecules of the extracellular matrix. Members of this family such as MMP-2, -9 and -7 have been shown to be associated with tumour progression and invasion in human cancer tissues. Matrilysin (MMP-7) influence the early stage of tumourogenesis.

In his classic book ‘The Ascent of Man’, Bronowski has written, “When I was a young man, we all thought that mastery came from man’s domination of his physical environment. Now we have learned that real mastery comes from understanding and moulding the living environment.” Our Biosphere, the living environment that supports us all, has problems and we humans are mainly responsible. We do not live ‘gently’ on the earth. The seven billion of us require air, water, food, energy, housing and amenities and we have developed the earth to provide them and have also created problems. That the problems exist are serious is the bad news. That we are recognizing them and that man has shown ability to organize and grow in ascending order from time to time is the good news.

1.1 The relation between man and the earth’s resources

The balance between the demand which a community of plants or animals makes on its environment and the ability to satisfy those demands is not the static equilibrium of a laboratory balance with equal weights on either side. It is more like the unstable balancing of a circus acrobat - a series of swings and overcorrections, resulting in an oscillation on either side of the true balance point. Thus a species of wild life increases in number according to the availability of its food supplies, but then goes beyond the optimum number. The natural correcting factors of starvation or migration reduce the population, but there is an overcorrection, and soon the cycle starts again with increasing numbers.

1.1.1 The Malthusian Thesis

In primitive societies the human population also oscillates about a mean as the limiting factors of starvation, disease, and war, maintain an uneasy balance against the natural tendency to increase. A serious imbalance arises when man learns how to modify the limiting factors, but allows the natural increase to go unchecked. The essence of the Malthusian Thesis is that the resulting instability is the inevitable order for mankind. The thesis is named after the English political economist Thomas Malthus who first gave it formal expression in MALTHUS (1966). In an age when significant improvements in health, hygiene, and the standard of living were just becoming possible, Malthus aroused great argument when he pointed out that these very improvements could lead to mi sery through overpopulation. The key point of Malthus’s argument is that population increases in what he called geometric ratio, what today we would call an exponential curve, because whenever there is an increase in population there are more people to produce the next generation, so the rate of population growth accelerates - in modelling terms a positive feedback loop. On the other hand, when we increase food production there is no feed-back loop, the best we can hope for is for a constant linear increase. The natural sequence is therefore for food demand to increase faster than food supply, leading at some point to food shortage.

Nuclear Disasters

What is NUCLEAR ENERGY or NUCLEAR POWER?

It is the energy released in nuclear fission or nuclear fusion.
Motive power generated by nuclear reactor.
Where atomic energy of a substance get converted in to electrical energy.

Background and Technology Intervention

Managed Aquifer Recharge (MAR) describes planned storage and treatment of water in aquifers which can provide cheapest form of new safe water supply for towns and small communities (British Geological Survey, 2006). It is a part of a groundwater manager’s tool which is useful for replenishing and re-pressurising depleted aquifers, controlling saline intrusion or land subsidence as well as improving water quality through filtration and chemical and biological processes. MAR can enhance volumes of groundwater abstracted through different package of measures and restore groundwater balance. It also plays a vital role in smoothing out supply and demand fluctuations, stabilizing over-exploited groundwater levels, reducing evaporation losses and runoff, maintaining environmental flows in streams and rivers, improving water quality and augmenting the reuse of waste and storm water. In recent times, MAR uptake has been very limited.

(I)  Management of Swine

Since early days, cattle, sheep and goats accompanied human beings where ever they migrated but it is not the same with swine because of its rearing in unhygenic conditions. Some communities started avoiding swine because of the foul smell from pigs and slowly it entered into the religious life of Muslims and Yashdies.

            In China since 4900 BC and in England before 800 BC swine production scripts are found in majority in these two countries and at present these countries are leading in swine production. Swine growth is very much influenced by the method of keeping and rearing them and that is why its managemental practices should always be given high priority.

Reproduction

The female piglet attain maturity in 6-7 months of age and has a weight of 60-80 kgs. Males take more time to attain adolesence. The breedable age of a female is 8-12 months when it has a weight above 100 kgs. Its heat period is for 2-3 days. It may conceive by artificial insemination after 2-3 days of heat. The gestation length is 114 days. Weighing may be done after one month of age. Females generally give birth to 6-10 young ones at a time. If more young ones are born, than there are increased chances of death of the young ones.

According to FAO estimates, about 50% total geographical area in India is under various degraded hazards and about 2.1 million ha of land is getting degraded and deforested annually (Sehgal et al. 1998). Out of that underground water in arid and semi-arid areas is saline or sodic in nature. While spices, medicinal and aromatic plants may be a boon for these areas, which not only withstand under adverse conditions but also could be productive and helps in mitigating these problems. However, other crops are remain less or unproductive in these areas.

Spices are low volume and high value crops and have tremendous export potential, which is witnessed by several invasions faced by this Indian peninsula during ancient time. Medicinal and aromatic plants have an equally market potential with the world demand of herbal products growing at the rate of 7 per cent per annum (Aishwath and Tarafdar, 2007). Seed spices and aromatic plants are the natural source of flavour, perfumes and fragrance widely exploited by essential oil industries in the world. Owing to considerable diversity of edaphoclimatic conditions ranging from temperate to tropical and arid to sub- humid that prevails in India and an array of medicinal and aromatic flora occurs in wild state. Many exotic essential oil bearing plants, including mints, citronella, geranium, patchouli, lavender and chamomile have been naturalized in India. As the country has emerged as one of the main producers of seed spices and some of the essential oils, theses plants are significant foreign exchange earners. Some of the aromatic plants especially grasses can sustain both biotic as well as abiotc stresses, even in the areas unsuitable for conventional crops (Aishwath et al., 2008). Most of the seed spices crops are seasonal crops and comes up well with limited moisture and nutrients. Therefore, under utilized natural resources can be utilized profitably by crop diversification.

Abstract

Chickpea is one of the major grain legume crops of the tropics and subtropics. It is the second most important pulse crop after pigeon pea in India and is commonly known as gram or Bengal gram is a versatile crop among the grain legumes with a total production of 11.6 (Mt) from 13.2m ha. However, it ranks fifth in the productivity after Fababean, pea, lupin, and lentil and ranks first among the pulses both in acreage and production. Whereas, area under pigeon pea 3.90 mha with a total production and productivity of 2.89 mt and 741 kg/ha, respectively and is commonly known as red gram or Arhar is a very old crop of India. The chromosome number of pigeon pea is 2n = 22 chromosomes. They are the rich source of protein and supplies a major share of the protein requirement of the vegetarian population of the country. Chickpea accounts for 70.7% of the world Chickpea production n India followed by Australia, Pakistan, Turkey, Myanmar, Ethiopia, Iran USA, Canada and Mexico. Both crops are used as an important source of protein in human nutrition and cattle feed. Chickpea is considered to have medicinal effects and it is used for blood purification. Chickpea contains 21% protein, 61.5% carbohydrate, 4.5% fat. Its seed is also rich in protein, starch, fiber, calcium, iron and niacin, malic and oxalic acid, which makes it one of the best nutritionally balanced pulses for human consumption. However, like any other pulses, the chickpea seed also contains antinutrional factors, which can be reduced or eliminated by cooking. Both crops enrich the soil fertility by fixing atmospheric nitrogen in the root nodules and improve the soil structure. It is also to improve soil fertility by biological nitrogen fixation which helps reduce the input cost for the existing crop. These crops usually receive few inputs other than labor, insecticides and seed. Chickpea is a crop of both tropical and temperate regions. Low yield of chickpea attributed to its susceptibility to several fungal, bacterial and viral diseases. In general, estimates of yield losses by individual insects and diseases range from 5 to 10% in temperate regions and 50 to 100% in tropical regions. Whereas, Pigeon pea can be attacked by more than 100 pathogens. These include fungi, bacteria, viruses, nematodes, and mycoplasma like organisms. Fortunately, only a few of them cause economic losses and the distribution of the most important diseases is geographically restricted. The diseases of considerable economic importance at present are Fusarium wilt, sterility mosaic, phytopthera blight and alternaria blight.

Whatever may be the nature and strength of resistance to the performance appraisal, management cannot relinquish this practice. Without employee appraisal, salary increases, reassignments or promotions cannot be administered rationally. Each of these areas has its specific problems and one of the solutions of modern times has been offered by an unusually promising frame work offered by Peter Drucker concept of Management by Objectives (MBO).
MBO calls on the subordinate to set his short-term performance goals in consultation with his superior. Goals explicitly state the actions which the employee will follow. Instead of being appraised in a traditional way by his superior, the subordinate appraises his own performance by evaluating it vis-à-vis the goals. Before establishing a goal, the individual studies his job, assesses his potentialities, and formulates some specific plans to reach the goal. The supervisor is not the evaluator, but directs the goal-setting process to ensure that it matches the objectives of the organization.

Introduction Hokersar wetland (34°06’ N latitude, 74°05’ E longitude), a Ramsar site and a protected wildlife reserve is located in the northwest Himalayan bio geographic province of Kashmir, back of the snow-draped Pir Panchal. The wetland shelters about two million migratory water-fowl during winter that migrate from Siberia and the Central Asian region. The wetland is fed by two inlet streams Doodhganga (from east) and Sukhnag Nalla (from west). It is the only site in Kashmir with remaining reed beds and serves as a migration route for specifically 68 waterfowl species from Siberia, China, Central Asia,and Northern Europe, including the Large Egret, Great Crested Grebe, Little Cormorant, Common Shelduck, Tufted Duck, and endangered White-eyed Pochard (Ramsar, 2021).

INTRODUCTION TO FINANCIAL MANAGEMENT

CONCEPT AND DEFINITION OF FINANCIAL MANAGEMENT: Financial management is an integral part of general overall management. The term ‘Financial management’ is managerial activity that is concerned with planning and controlling of financial resources of a firm. Financial management is concerned with managerial decisions that result in the acquisition and financing of long and short-term credits of the farm or any enterprise. Financial management is concerned with the efficient use of all important economic resources that is capital funds of a firm (Solomon Ezra)

Financial management is an application of general managerial principles to the era of financial decision-making. (Howard &Uptron).

Financial management is an area of financial decisions making, harmonizing individual motives and enterprise goals.(Weston & Brigham).

Financial management is an operational activity of a business that is responsible for obtaining and effective utilizing the funds necessary for efficient operations.(Joseph & Massie)

Theory

  The term ‘Management’ derived from word ‘manage’ derived from French word menage means ‘housekeeping’.

 According to Knootz and Weihrich 1988, ‘Management as the process of designing and maintaining an environment in which individuals, working together in groups, efficiently accomplish selected aims’. 

According to Louis E.Boone and David L.Kurtz ‘management as the use of people and other resources to accomplish objectives’.

POSDCORB is an acronym widely used in the field of Management and Public Administration., it first appeared in a 1937 staff paper by Luther Gulick and Lyndall Urwick. The acronym stands for steps in the administrative process: Planning, Organizing, Staffing, Directing, Coordinating, Reporting and Budgeting.

A management information system (MIS) is an organized collection of people, procedures, software, databases, and devices used to provide routine information to managers and decision makers. The focus of an MIS is primarily on operational efficiency. Marketing, production, finance, and other functional areas are supported by MIS and linked through a common database. MIS typically provides standard reports generated with data and information from the transaction processing system (Fig. 13.1)

Introduction

Forest trees constitute ~82% of the continental biomass and harbour >50% of the terrestrial biodiversity. They also help to mitigate climate change, and provide a wide range of products that meet human needs, including wood, biomass, paper, fuel and biomaterials. Field-grown trees are routinely exposed to environmental stress. Current and predicted climatic conditions, such as prolonged drought, increased salinisation of soil and water and low temperature episodes pose a serious threat to forest productivity worldwide, affecting tree growth and survival. According to the reports of the Intergovernmental Panel on Climate Change, these stresses will increase in the near future because of global climate change.

Introduction

India is a second largest producer of fruits after China contributing about 11 per cent to the global production. India leads the world in productivity of papaya, grapes and banana but average productivity of country is much below as compared to other leading countries, which is merely 11.6 t/ha. Abiotic stress is the primary cause of crop loss worldwide, reducing average yields for most major crop plants by more than 50%. Drought and salinity are becoming particularly widespread in many regions, and may cause serious salinization of more than 50% of all arable lands by the year 2050 (Wang, 2003). This leads to a series of morphological, physiological, biochemical and molecular changes that adversely affect plant growth and productivity. There are various factors, which contributes to low productivity like limited availability of quality planting materials, old and senile orchards, poor orchard management practices, insect pest and diseases, poor post-harvest management practices etc. There is a much scope in expansion of horticultural crops in arid region and it has vast potential for changing scenario of horticulture of the country. Land resource, surplus family labors, increasing canal irrigated area, developing infrastructural facilities, plenty of solar and wind energy, etc. are the strength in the region for research and development of arid horticulture. Further, low incidence of diseases/insects in the region provides good scope for production of quality seed and planting material of horticultural crops (Sharma et al., 2013).

The National Bureau of Plant Genetic Resources (ICAR-NBPGR) was established in 1976 in New Delhi by the Indian Council of Agricultural Research (ICAR). The mandate of the Bureau was to act as a nodal institute for the acquisition and management of indigenous and exotic plant genetic resources (PGR) for agriculture and to carry out related research and human resources development for sustainable growth of agriculture. As we know our country is a mega-diverse country with 2.4% of the land area, accounting for 7.8% of the recorded species of the world spread over 45,968 (11.18% of world) species of plants and 91,212 species of animals (7.43% of the world) that were documented in its 10 bio-geographic regions. India shares four biodiversity hotspots, namely Western Ghats and Sri Lanka, the Himalayas, Indo-Burma, and Sundaland, and one third of our species of higher plants are endemic. Out of 45,968 plant species, 5150 are endemic and distributed in 141 genera under 47 families, corresponding to about 30% of the world’s recorded flora, which means 30% of the world’s recorded flora is endemic to India. The plant genetic resources are fundamental to human welfare and their effective management is a crucial for conservation of genetic variability. As of today, ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi, India has conserved about 4.6 lakh accessions of 1900 species in its gene bank, and about 6900 accessions of intermediate species have been conserved in cryobank. The Bureau not only conserve PGR safely to meet the needs of future generations but also provides these to the nation’s crop improvement programs to sustain continued advances in agricultural productivity and stabilize production. ICAR-NBPGR is the nodal agency for import and export of all PGR for research purpose, adhering to guidelines of National Biodiversity Act, 2002.

The agricultural production is inherently a risky business characterized by seasonality; perishability and variability which make it susceptible to vagaries of climate and markets and thus farmers face a variety of agricultural risks. In response to these risks over a period of time, several risk management mechanisms have been evolved. Risk management strategies refer to ex-ante measures taken before such an event has taken place, whereas risk coping strategies are, ex-post strategies dealing with the consequences of the event (World Bank Report, 2005). Invariably, farmers use both ex-ante and ex-post strategies. It is interesting to note that so far agriculture risk management has been in terms of risk avoidance and risk reduction and mostly these risks are addressed at farm or production level. Currently there has been a shift in agriculture risk management from risk avoidance and risk reduction strategies to risk mitigation strategies. Similarly, there exist shifts from production to market orientation in agriculture. To understand this phenomenon involved, it is felt necessary to study the agricultural risk management behaviour farmers. Keeping this discussion as focal point, the study was conducted with an objective to assess risk management behaviour of farmers.

Animal flesh when consumed as food is known as meat. Meat was introduced into man’s diet early on during Stone Age when they were hunter and gatherer. Humans seem evolved to a meat diet based on the structure of teeth and the unsophisticated nature of our digestive system. Presently man used many varieties of animals’ species for producing meat however domesticated cattle, goat, sheep, buffalo, pig and poultry continue to be major contributor of meat to the ever increasing human population. Meat is one of the best and major sources of protein for human, meat protein content all the essential amino acid in required quantity and is easily assimilated by human guts. Fat is essential for development of flavor; at least the bare minimum is desire. Besides this it also has all the other crucial nutrients in smaller amount.  The essential elements of good quality meat are firm texture, moderate fat content, tender, good flavour, juiciness and normal meat odor, and to produce such meat it require proper care and management of meat animal. Hence, right and efficient management is to be given to the animals for producing better meat quality. Management broadly includes selection of genetically superior animals,

1.0 INTRODUCTION

The bacteria in the genus Ralstonia, Xanthomonas, Agrobacterium, Xylella, Pantoea, Leifsonia, Curtobacterium, Enterobactor, Pseudomonas, Corynebacterium, Erwinia cause the most important bacterial diseases of crop plants. Few of them are directly responsible for post harvests losses during storage or transit and many of them are known to cause disease in the field. These diseases are economically important due their potential to cause crop failure in crops including spice crops. Among the bacteria genus Ralstonia is very important owing to its broad host range across the plant kingdom. Traditionally bacterial diseases of crops are prevented by the principle of ‘Disease Avoidance’ rather than disease control in the field. Their fast rate of multiplication, selective host and rapid spread in the field makes the disease control one of the challenges in the production system. The organic strategies are very well fit in the disease avoidance in the field. The preemptive strategies works exceedingly well for management of bacterial disease in any crop. Few genus such as Ralstonia, Enterobacter and Xanthomonas have been frequented in spice crops.
