44.1 Introduction

Ornamental fish are a diverse and colourful species benefiting millions of aquarium enthusiasts. The term "ornamental fish" was first coined in the early 19th century to describe fish kept solely for decorative purposes by ancient civilizations such as the Sumerians and Egyptians.

They are known for their shapes, sizes, vibrant colours, intricate patterns and distinct behaviours with hobbyists and collectors. They are widely used to distinguish between fish kept for food or other practical purposes.

A garden has a number of elements which give shape to its breath-taking view. Both animate and inanimate elements are included to achieve a beautiful garden The living elements are lawns, rock garden, water garden, sunken garden, hedges, edges, shrubs, topiary, flower bed, specimen plants, pergola and arches, while the inanimate elements, also called as adornments, are stones, road, footpaths, seats, lamps, lanterns, steps, bridges, huts, swings, fountain, cascade, bird bath, clock tower, umbrellas, sculptures etc.

Gingers  belong to Zingiberaceae family and are made up of about 1000 species in 47 genera. They have numerous members with aromatic oils that have made them popular for perfumes and ornamentals. Ornamental gingers, while related to edibles, are usually grown for their looks instead of their flavor. A very large and diverse group of gingers are valued both for their tropical foliage and for their large, colorful flower heads. From the startling red ginger to the subtle shell ginger, these attractive plants are easy to grow in home landscapes in tropical and semi-tropical areas. They are great for tub gardens They can be very rewarding to grow, and with some simple care will continue to produce beautiful leaves and flowers for many years which also have cut flower value.

Grasses, bamboos, sedges and rushes are plants that are being used increasingly in xeri-scaping and in marsh gardens for getting the benefits of their unusual foliage textures and colours. Their hardiness, stature and canopy frame make them more suited for specimen planting in gardens and landscapes.

GRASSES

Grasses are the most successful of monocots belonging to the family Poaceae that are found the world over. Low growing perennial grasses are used to make attractive lawns in gardens and to provide a desirable turf cover for various situations. A number of species belonging to various genera differing in leaf colour, shape and growth pattern are used for this purpose. Mixtures of different varieties of grasses are also used for making turf having desirable blends of textures and hardiness. Tall bushy grasses having a mound-like or fountain–like habit and fine to velvety surfaces are grown for their textural and architectural features in landscaping. Many are grown as specimen plants for their display value at flowering. In selecting grasses for gardens, their potentially invasive nature is to be taken into account and seed dispersal controlled by timely cutting.

Grass species that thrive in the hot and humid tropics are called warm-season grasses and include Bermuda grass, Carpet grass and St. Augustine grass. Cool season grasses that are adapted to temperate regions and thrive at temperatures of 10 to 20^oC include Blue grass, Fescues and Zoysia.

1. Introduction

Nursery is a place, where seedlings and saplings of different ornamental plants (trees, shrubs, climbers, annuals, potted plants etc.) are propagated and maintained until they are out-planted in a prepared bed or in pots. Establishment of an ornamental nursery is emerging as a profitable venture, especially around cities. Rapid urbanization has led to the development of community parks and various sites for people to engage in active and passive recreation. This has led to surge in demand for quality planting material, which ensures rapid establishment and beautification of the landscape site. The following chapter deals with the basic principles and practices of establishment of ornamental plant nursery, with reference to its effective management to enhance the income and reap better profit.

Ornamental Plants are a real attraction to the aquarium tank. While some plants are both ornamental and functional, people usually use the term “ornamental plants” to refer to plants which have no value beyond being attractive, although many people feel that the attractive value itself is quite enough. They provide optimal habitat for the fishes especially for the fry (baby fishes). It maintains the ecosystem of the aquarium tanks by providing good oxygen, food and also acts as a good hiding place for the baby fish. Mostly all aquatic plants are very easy to grow and care. They are always good for gold fish and other similar fishes. There is a huge variety of plants. Ornamental plants are grown for decoration, rather than food or raw materials. They are most often intentionally planted for aesthetic appeal. However, ornamental plants also serve some less obvious uses such as for the purpose of fragrance, for attracting wildlife and for cleaning the air. Ornamentals encompass a wide array of plants. Commonly, ornamental plants are grown for the display of aesthetic features including: flowers, leaves, scent, overall foliage texture, fruit, stem and bark, and aesthetic form. The concept of ornamental plants is used for decorative purposes in aquariums, gardens, home gardens, landscape design projects, squares, parks etc.

Aquatic plants predominantly grow in water. They vary greatly in type, with some being quite similar to common land plants while others are quite different. Aquatic plants can be commonly classified into four types: algae, floating plants, submerged plants and emerged plants. Aquatic plants live in water. This means that they require being submersed to survive or that they can only grow and thrive in water. Many aquatic plants can tolerate being emerged, meaning they’re out of the water for short periods of time, but require immersion in water for long-term survival.

There are some plants that simply can’t tolerate being emerged at all, but this is rare. These plants can only live when fully immersed in water. Most macro- algae require total submersion in water for the span of its entire life. Most aquatic plants, however, have roots underwater but can only grow or flower in a partially emerged state. All plants, aquatic and otherwise, require sunlight, soil, gases and water to survive. Plants make their own food via the process of photosynthesis; this means that they need a source of energy to drive this biochemical process, and the sun provides a perfect one. Plants can carry on for periods without sunlight, just as animals can live on stored fuel for a while in times of need. The soil offers a place for the plant’s roots to take hold.

Air contains large amounts of the carbon dioxide gas (CO2), plants need to power photosynthesis, but aquatic plants have evolved to draw in CO₂ that is dissolved in water in relatively small amounts. Finally, plants need water to combine with the CO2 to complete photosynthesis by generating oxygen and glucose.

Shrubs are defined as woody, semi woody or herbaceous perennial plants, branches arises from the base of the plants and grow up to height of about 0.5 to 4.0 meters. These plants are commonly erect and bushy. Most of the shrubs are very hardy, require little attention and grow in all types of soils. Although some plants flower almost throughout the year, in most cases it is seasonal and selection can be made in such a way that some plants in the shrubbery will be in bloom in different seasion of the year. Shrub flowers regularly every year and produce flowers of almost all the important colors white, light yellow, golden pink, scarlet, crimson, violet, blue, and some are sweet scented.

In gardens, shrubs are usually planted in three ways:

(1) In the form of shrubbery, on the long strip of land where taller shrubs are grown at the back with medium height in middle and dwarf once at the fronts. Colors of flowers and time of flowering are also considered so that shrubbery remains colorful throughout year with bloom and foliage.

(2) In small garden or to break monotony of open space shrubs are often grown in groups and in this case few plants of the same variety or of different species are selected.

(3) Shrubs are also grown as a specimen plant or in only one row along the border of the garden or a wall.

Shrubs are used in gardens for decorative purposes as these shrubs are found more in ornamental and provide a variety of interests. They are evergreen and best against noise and dust. Any perennial woody, perpetual and thick plant of relatively low height that branches into a few stems or trunks arising from the ground base is known as shrub. They are littler than a tree but taller than herbaceous plants. They are also called as bushes when they are much-branched and dense. They grow upwards up to 0.5-4.0meter and may be flowering and ornamental. Shrubs play important role in permanent landscaping i.e. formal decoration which contributes pattern, colour, fragrance and utility. They may be either evergreen or deciduous in nature. Some shrubs have attractive foliage, flowers and attractive berries. Shrubs are planted as borders on the sides of paths and at the corners of lawn in a curving line. Shrubs are used for back ground, boundary wall, screen, shade, wind breaks and foundation planting. Hence, knowledge on the form, growth habit and habitat is essential to select the shrubs for planting. Shrubs are important part of landscaping or landscape designing is an art of modifying the overall appearance of a given piece of land using different ornamental plants. It is an artificial process. A garden or national and international playgrounds are the example of artificially landscaped area. Ornamental plants are a group of different flowering, foliage and stylish plants. These plants are used for the beautification of selected part of a site or other places.

Shrubs are main filler plants of the gardens and have wide range of variation with regard to growth, leaf texture and flower (shape, size and colour). They continue to bloom all most round the year and help to keep the gardens presentable. These are the reasons for selecting shrubs for plantation in every type of garden. The way shrubs influence general landscape with their exquisite shape, size, foliage, flower and fragrance are incredible. In residential and small gardens, there may be limited room for planting trees but accommodating shrubs is never a problem as they occupy small space. Similarly, large parks and gardens are also ideal place where the shrubs can be fully utilized in various ways.

Classification

Availability of shrubs is large in numbers. Selection of right type as per design of the garden, is an important task as these are main filler plants of the gardens. Basic knowledge on growth habit and flowering is necessary for their judicious use. Therefore, shrubs have been classified on the basis of height, growth habit, foliage, flower colour, fragrance etc. for facilitating proper selection.

Ornamental plants that are adapted to an aquatic environment are commonly grown in water gardens and pools. They include those that are entirely submerged or floaters that are free living in the surface water or having roots anchored firmly in the ground beneath and marginal plants that thrive along the edges of water bodies and in shallow water. Spectacular flowering plants like the lotuses and water lilies to plants like the tape grass that are entirely submerged and grass like are grown in natural or structured fresh water habitats throughout the world. Many of these are also inhabitants of aquaria.

Some of the popularly grown water garden plants are listed below:

Acorus calamus

Araceae

Sweet Flag, Vayambu

Plants are rhizomatous herbs adapted to low lying and wet situations. The leaves are closely spaced, distichously arranged and resembling a fan, leathery, dark green, smooth and shiny. The inflorescence is a spadix that emerges from the middle of the terminal leaf. Plants are valued medicinally for their aromatic rhizomes and are also commonly grown as marginals of water gardens.

Jasmine

Jasmine oil and its synthetic substitutes are extensively used in high grade perfumes in the western countries, the main buyers being USA, France, UK, Japan, Holland and Russia. Essential oil production is an export oriented agro industry in Egypt, France, Morocco, Belgium, Germany, Tunisia, Italy, Algeria, China and India. It is also used for perfuming expensive soaps and cosmetics, mouthwashes and dentifrices. 

Jasmine oil is unique and the odour of jasmine cannot be imitated by any known synthetic chemicals. There is hardly any perfume of floral origin which does not contain at least a small quantity of jasmine concrete or absolute. The world production of jasmine concrete is approximately 20 tones/year and India’s production is 2 tones.

Etiology

Ornithobacteriun rhinotracheale, bacteria, under phylum Cytophaga- Flavobacterium-Bacteroids. It is Gram negative non-motile, non-sporulating pleomorphic rod shaped bacteria. 18 serotypes Athrough R have been identified. Serotype A is prevalent in chicken and turkeys.

Disease occurrence

The disease is worldwide in distribution.

24.1 Introduction

Water is a universal biological solvent and the medium in which most of the cellular reactions of metabolism occur. Fish contain a large amount of water in their cells and extracellular fluids. It is important to a fish that its water content be nearly constant. This more or less steady state of water content in the body can only be maintained when there is a quality difference between the amount of water entering and leaving the body. The process of regulating the movement of water and its volume in the body is known as osmoregulation.

Abstract

Osmotic dehydration is gaining popularity due to several energy and product quality related advantages it offers. It has huge potential as a complementary process step prior to operations such as air-drying, microwave drying, freezing, frying etc, if not an alternative one, in the food process chain. It can be easily integrated with other processing steps in order to improve the overall efficiency of a given food process. Application of additional driving force either prior to or during osmotic dehydration can enhance the mass transfer rates in the osmotic dehydration. Role of mathematical modelling both in osmotic dehydration and rehydration have been discussed. Current limitations for the adaptation of osmotic dehydration in the food processing industry and possible solutions are also discussed in detail.

Introduction

The drying of fruits and vegetables during the season of abundance in order to preserve them for consumption during season of shortage is an ancient practice. Thus, drying is one of the oldest methods of preservation of the food commodities. It is practiced from ancient times and is a very common method of preservation in the tropical countries like India where conditions are much more favorable for sun drying. All micro-organisms need moisture to grow. So the removal of water in the food is brought down below a certain level at which they are unable to grow. Moisture content from food can be removed by different methods like sun drying (very oldest method and most popular), solar drying, cabinet drying, mechanical drying, tunnel drying, poly tunnel drying, adiabatic drying, spray drying, osmotic drying, fluidized bed drying etc. Grains are mostly dried in the sun. The moisture content of the grains can be reduced to a limit that is safer for their storage by sun drying. Many fruits and vegetables can also be dried by using sun energy. Some coastal areas of the countries fishes are also dried by exposing to the sun. After drying, sometimes the dried products are converted into powder. However, these powders are very hygroscopic and should be packed in airtight. Mango powder is prepared by this technique, but expensive and not popular in India. Nowadays many artificial methods have been developed for removal of the moisture. The relationship between the moisture content and temperature of air during process is referred as Psychrometric relation. An instrument used to measure the humidity (Relative humidity) of the atmosphere is known as Psychrometer (Hygrometer). The residual moisture in vegetable should not be more than 6-8% and in fruits it should be in the range of 10-20%. The dried fruit can be used as such or after soaking while dried vegetable are usually soaked in water overnight and then cooked. Vegetable are considered to be dry when they become brittle. There are generally two drying methods for foods like 1) Natural drying and 2) Artificial drying. The preservation / stability of the dehydrated products is conferred by the abstraction of water, so that the product is unable to support the microbial growth, its chemical forms of deterioration is inhibited and the drastic reduction in the weight / volume facilitate easier handling and marketing. Among dehydrated products, dehydrated onions have largest share of 45%. India is the third largest exporter of the onions in the world next to the Netherland and Spain. Besides this, India exports dehydrated bell pepper, garlic and mushrooms.

A metabolic cell contains about 75-95% water by weight. It is important for plants for proper growth and development. Any significant reduction in availability will affects metabolic activity and thus growth parameters which determine yield. The uptake of water by the plant (roots) from the soil is an osmotic phenomenon. The water potential represents the free energy per moles of water. It can be reduced by:

1. Decreasing temperature
2. Adding soluble pressure or
3. Decreasing pressure or
4. Providing additional absorptive surface

Introduction

The demand of diversified food has increasing due to health consciousness in the modern civilization. The European communities have gone in search of new foods which contributed mainly to the health diet of population. In this process, animal and avian species have contributed to a large extent in providing the required health foods like milk, meat and eggs. The tendency to go for low calories foods has resulted in increased demand for new species for meat purpose. At present, the ostrich meat ranks highest among health food in Europe. Ostrich meat in terms of health value is credited to less percentage of fat, low cholesterol, less calories, rich in protein and iron. The demand of ostrich meat has been increasing especially after the threat of mad cow diseases. The unique taste of ostrich meat has been added into different meat dishes. This meat has a great demand in restaurant in Europe, Japan, Australia and China in a big way. The popularity of this bird can be judged from the fact that presently 65 countries, including our neighbor Pakistan and China are engaged in ratite farming. The increased demand of ostrich over the past few years has given way to rearing birds under controlled system. The intensive system become popular because of adoption of scientific technologies reduced risk of diseases, through improved bio-security measures, genetic selection and nutritional innovation, health regimes and extensive diseases surveillance. Scientifically proven management practices resulted in low cost production and improvement in quality of ostrich products.

Potato (Solanum tuberosum L.)

Potato is the third most important food crop in the world after rice and wheat in terms of human consumption. Potatoes are an important staple food crop. Introduced into Europe in the 16th century by Spanish explorers, it is cultivated throughout the world including the Indo-Pakistan subcontinent.

Botanical Name : Solanum tuberosum L.

Family : Solanaceae

Importance

• Potato is an economical food, as it provides a source of low cost energy to human diet.
• For vegetable purposes, potato has now become one of the most popular crops in India and cultivated in almost all states and under very diverse agro climate conditions.
• Potatoes are a rich source of starch

13 1. Rishi Krishi

Drawn from Vedas, the Rishi Krishi method of natural farming has been mastered by farmers of Maharashtra and Madhya Pradesh. In this method, all on-farm sources of nutrients including composts, cattle dung manure, green leaf manure and crop biomass for mulching are exploited to their best potential with continuous soil enrichment through the use of Rishi Krishi formulation known as “Amritpani” and virgin soil. 15 kg of virgin rhizosperic soil collected from beneath of Banyan tree (Ficus bengalensis) is spread over one acre and the soil is enriched with 200 lit Amritpani.

It is prepared by mixing 250 g ghee into 10 kg of cow dung followed by 500 g honey and diluted with 200 lit of water. This formulation is utilized for seed treatment (beej sanskar), enrichment of soil (bhumi sanskar) and foliar spray on plants (padap sanskar). For soil treatment it needs to be applied through irrigation water as fertigation. The system has been demonstrated on a wide range of crops i.e. fruits, vegetables, cereals, pulses, oilseeds, sugarcane and cotton.

Aconites, the tuberous roots of which contain highly toxic alkaloids, are deadly poisons. In small doses, aconites are beneficial in nasal catarrh, sore throat, gibbous, paralysis and chronic fevers. Aconitum is a genus of perennial, erect or rarely twining herbs distributed over North temperate regions of world. The mountains of Eastern Asia form the primary centre, presenting the greatest diversity of genus. About 28 species are reported from India, mostly confined to alpine and subalpine belts of Himalayas. Of the Aconitum spp. occurring in India, roots of nine species are obtained in Indian market. In fact, aconite sold in Indian market is a mixture of 304 species. Still, A. ferox, known as Indian Aconite, is considered the most important.

A. ferox is a perennial herb with tuberous roots. Roots are paired, daughter tuber, ovoid oblong to ellipsoid, with filiform root fibres. Leaves are scattered, orbicular-cordate to reniform, palmately 5 lobed, resembling melon leaves. Petioles are pubescent. Flowers are pale dirty blue, borne in a dense terminal raceme, 10-25 cm long. Follicles are oblong with long, obovoid winged seeds.

10.1. CADMIUM
10.1.1. Introduction

Cadmium (Cd) is a strongly phytotoxic heavy metal in an increasing environmental problem worldwide. It is one of the most dangerous metal due to its high mobility and the small concentration at which its effects on the plants being to appear. It is released into the environment by the power stations, heating systems, metal-working industries or urban traffic. It is recognized as an extremely significant pollutant due to its high toxicity and large solubility in water (Pinto et al., 2004). Soil solutions which have a Cd concentration ranging from 0.32 to 1.00 mM can be regarded as polluted to a moderate level (Sanita di Toppi and Garbrielli, 1999).

Introduction

Rice is the world’s most important staple crop and is a primary source of energy and nutrition for about half of the world’s population. So it is the most important cereal crop with respect to food security of common people. Due to increasing world population and shrinkage of farm land holdings there is an urgent need to increase the grain productivity. Therefore, increasing grain yield has become the primary objective in many rice-breeding programs. India is the second highest rice producer (about 120 million ton/year) in the world and able to meet the demand of rice for the entire Indian population. But along with yield improvement of rice, quality has now become a foremost consideration for rice consumers and millers. Quality is defined as “the totality of features and characteristics of a product or service that bears its ability to satisfy stated or implied needs” (International Standard Organization (ISO) 8402 1986). The concept of grain quality covers many physico-chemical properties such as grain shape and size, milling and cooking properties, amylose content, stickiness, chalkiness, texture, colour, gelatinization characters and various nutritional properties. Thus, rice grain quality generally includes five main classes i.e. (i) milling quality, (ii) physical quality, (iii) cooking and eating quality (iv) sensory quality and (v) nutritional quality. Grain quality and its assessment are very important to consumers, millers and rice breeders who are engaged in varietal improvement programme, related to new features such as high nutritional quality, high yield potential, highly resistant to abiotic or biotic stresses, higher water use efficiency etc.

Pig Production on Scavenging

Pig farming has become a profitable enterprise since it possesses many economic traits e.g. high prolificacy, faster growth rate, shorter generation interval, low cost of rearing and high dressing percentage with better feed conversion efficiency. Pigs give quick return, convert inedible feed into valuable products, require less labor, adopt most types of farming systems, aid soil fertility, supplement other enterprises, etc. It is still considered as backward profession and unorganized rearing largely dominates the sector, and it is primarily in the hand of poor, landless and weaker section of society.

Integrated Watershed Management Programme (IWMP)

Integrated Watershed Management Programme (IWMP) is a modified programme of erstwhile Drought Prone Areas Programme (DPAP), Desert Development Programme (DDP) and Integrated Wastelands Development Programme (IWDP) of the Department of Land Resources. The scheme was launched during 2009-10. The programme is being implemented as per Common Guidelines for Watershed Development Projects 2008. The main objectives of the IWMP are to restore the ecological balance by harnessing, conserving and developing degraded natural resources such as soil, vegetative cover and water. The outcomes are prevention of soil erosion, regeneration of natural vegetation, rain water harvesting and recharging of the ground water table. This enables multi-cropping and the introduction of diverse agro-based activities, which help to provide sustainable livelihoods to the people residing in the watershed areas.

Ajowan is a profusely branched winter annual herb, seed oil of which is a major source of thymol, being present to extent of 35-60%. Ajowan oil is aromatic, stimulant and carminative.  It possesses antimicrobial activity. Ajowan seeds are employed either alone or in combination with spices and condiments. It is used in pickles, confectionery and beverages.  It is a good remedy for indigestion.  A paste of crushed fruit is applied externally for relieving colic pains.  It is also used in lotions and ointments.

In addition to farm ponds, irrigation to crops can be met from other sources. The main sources can be broadly classified as: (i) Canal irrigation, (ii) Well Irrigation and (iii) Lift irrigation. In arid and semi arid areas, where availability of water is scarce, pitcher irrigation is practiced. These sources of irrigation are briefly mentioned as follows.

13.1 Canal Irrigation

To feed the world population of 8 billion in 2025 AD, it is necessary to bring more area under irrigation because irrigated farms typically get higher yield under provision of irrigation. The food production will have to increase by about 50 percent to feed some two billion more people by 2025 AD, and a large part of that increase needs to come from irrigated agriculture. It is reported that the yield of different crops are generally 2-3 times higher than the crops grown under rainfed conditions. Furthermore, it is possible to raise 2-3 crops round the year under irrigated agriculture whereas hardly a single crop is successfully grown in a year under rainfed condition. It is reported that about 40% of the world’s food production comes from only 17% of the irrigated land of the world (Sivanappan, 2000). Everybody is aware of the fact how the irrigation played a crucial role to make the Green Revolution in India successful. A major part of irrigation is achieved by canal irrigation through different irrigation schemes.

A project that makes use of weir or a barrage for providing irrigation to fields is called as direct irrigation scheme. On the other hand, a storage irrigation scheme makes use of storage reservoir by construction of dams. In order to provide irrigation by both the schemes, it is necessary to have a network of canal systems including main canals, branch canals, distributaries, minors and watercourses. It is imperative to design the canal systems properly for a certain realistic value of peak discharge that must pass through them so as to provide sufficient irrigation to the command areas. These canals have to be aligned and excavated either in alluvial soils or non-alluvial soils; depending upon which they are called alluvial canal or non-alluvial canal.

Garlic is recognized all over the world as a valuable condiment for food and medicine. It is a native of Western Asia and Mediterranean area where it is in cultivation for centuries. China, Korea, India, USA, Spain, Argentina and Egypt are the major garlic growing countries, China being the largest producer (Pandey, 2004). Europeans, especially the Italians and the Spanish used this spice regularly for 2000 years and more. Garlic is one of the important spicy bulbs grown commercially in India. The plant is cultivated in temperate and tropical climates. Important states producing garlic on commercial scale are Gujarat, Maharashtra, Tamil Nadu, Karnataka, Andhra Pradesh, Madhya Pradesh, Orissa, Uttar Pradesh and Haryana. Demand of garlic is increasing day by day in domestic and export markets. Garlic and garlic products, especially dehydrated garlic and garlic powder are gaining considerable economic importance recent times.

Our Soils – Our Waters & COP22

In the last several decades many international forums and institutions have discussed and agreed that food and water security are the most important issues for the future. The damage to the ecology directly affects the food, land, water, health and the livelihood. Agricultural progress serves as the best way to fight poverty, hunger and livelihood problems.

Though in the last few decades, billions of pages about hunger, food and water security have been written, thousands of conferences have been organized, the urgency of action plans and creating holistic models is the most important need. For this, we must require bold reforms and action oriented programs which can reach the smallest farmers and give an optimistic signal rather than a despondent picture. Developmental models that are holistic and close to nature, sustainable and based on inclusiveness considering ‘unto the last’ women and man are the need of the day.

Democracy has been one of the most generally adopted forms of government around the world. Democracy, founded on the values of popular sovereignty, equality, and civic involvement, seeks to give the people political authority. Democracy has had a variety of consequences and impacts on the society and governments that have accepted it throughout history. These outcomes have shaped people's lives, influenced political landscapes, and had far-reaching consequences in the social, economic, and cultural arenas. Ofcourse, democracy may face challenges, its ability to adapt, evolve, and engage citizens in the decision-making process makes it a crucial system for fostering inclusive and prosperous societies. Below, we will explore some of the positive outcomes and challenges before democracy.

The overall number of animals kept as livestock in India comes to 535.78 million, making it the country with the greatest livestock population. According to the 20th Livestock Census, India has a total bovine population of 302.79 Million. This includes Cattle, Buffalo, Mithun, and Yak. There are a total of 109.85 million buffaloes living in the country. The number of goats in the country currently stands at 148.88, while the total number of sheep in the country is 74.26 Million. Most of the breeds in India have evolved naturally through adaptation to varied agro-ecological conditions and have generally been named after their place of origin or on the basis of prominent morphological characteristics. The number of registered breeds in India has increased over time. Majority of livestock breeds are reared by smallholder farmers are of non-descript type. Indiscriminate crossbreeding is extensively occurs resulting in herds of females that may have very complex ancestries.

Captive breeding programme is generally considered as a process of breeding animals in controlled environments within well-defined settings, such as wildlife reserves, zoos and other commercial/noncommercialconservation facilities.Use of modern reproductive biotechnologies or assisted reproductive techniques (ART) include in general artificial insemination, embryo transfer/sexing, in vitro fertilization, gamete/embryo micromanipulation, semen sexing, genome resource banking, and somatic cell nuclear transfer (cloning) in conservation programs for endangered mammalian species.

Veterinarians, biologists, field assistants, hunters, and other individuals who work directly with wildlife have an increased risk of acquiring these diseases directly from animal hosts or their ectoparasites. Plague, tularemia, and leptospirosis have been acquired in the handling and skinning of rodents, rabbits, and carnivores.

Introduction

The Over-head insulator for overhead lines provides insulation to the electrical conductor. It is connected to the cross arm of the supporting structure and the electrical conductor passes through the clamp (insulator). It is mainly made of either glazed porcelain (Silica 20% + Feldspar 30% + Clay 50%) or toughened glass. The porcelain must be free from any defect. It should be vitrified because the presence of pore or air will lower down its dielectric strength. Any captured air impurity will also reduce the dielectric strength of the porcelain. Therefore, it is highly desirable that the insulators should be air free and resistant to the entrance of liquids/gases. It is desirable not to allow porcelain to come in direct contact with a hard metal screw thread. Therefore, cement is used between metal and the porcelain.

Introduction

Fisheries and Aquaculture remains to be an important source of food, nutrition, income, and livelihood to millions of people. Fish is an affordable and good source of animal protein, a good option to reduce hunger and malnutrition in the country. India has bountiful resources comprising inland, brackish and marine water along with diverse fish and shellfish species. Indian Fisheries sector evolved gradually over the years and became an important socio economic attribute for the nation. India is the third-largest fish and aquaculture producing country and accounts for about 16% of total inland and 5% of total global marine fish production respectively. In 2021-22, India’s total marine and inland fish production stood at 16.24 million metric tonne (MMT), which includes 12.12 MMT and 4.13 MMT from inland and marine sectors, respectively. The annual growth rate in the marine sector was observed at around 18.7 %, whereas inland sector achieved more than 7.76 % during 2021 22 ( Table 17.1).The fishery potential of the country has been estimated to the tune of 22.31 MMT out of which Marine fisheries potential is 5.31 MMT and Inland fishery potential is 17 MMT. (Table 17.3).

Marine fisheries activities are spread along the country’s long coastline (8118 km) and in the vast Exclusive Economic Zone (EEZ 2.02 million km2). The inland resources are in the form of rivers and canals (0.19 million km), f loodplain lakes (1.0 million ha), ponds and tanks (2.43 million ha), reservoirs (3.15 million ha), brackish water (1.18 million ha), saline/alkaline affected areas (0.24 million ha), and such others etc., covering about 9 million ha, providing livelihood to 16 million (Table 17.2). In this direction sea cage culture may play an important role in rapid expansion of seafood production at global level. In present scenario, due to limited availability of fish fingerling we may not expand sea cage culture to the optimum level. Therefore, need of hour is to strengthen the available infrastructure and other needed backward and forward support system enhancing for fish seed production apart from developing market linkages with diversification of species.

Introduction

The 21st Century agriculture needs knowledge integration and maximum input efficiency. Crop simulation models offer possibilities to evaluate and target agricultural information towards sustainability (Elliott et al., 2015; Van Oort and Zwart, 2018). All the modern day’s crop growth models not only predict the growth and yield, but also they are strong Decision Support System (DSS). Due to the impact of climate change, land degradation and biodiversity loss, the agricultural production system becomes the most vulnerable one (Araya et al., 2017). Crop intensification is inevitable to meet the ever-increasing food demand for the billions of populations. It leads to deterioration of soil physical health, reduction of the organic carbon percentage and micro-environmental pollution. Conservation agriculture (CA) has a great potentiality to enhance the inherent resilience against all sorts of degradation and possess the potentiality to regenerate the degraded lands (Haggblade and Tembo, 2003). CA is a farming system that maintains a permanent soil cover to assure its protection, avoids soil tillage, and cultivates a diverse range of plant-species to improve soil conditions, reduce land degradation and increase water and nutrient use efficiency (Friedrich et al., 2012; Sapkota et al., 2015; Bell et al., 2019; Steward et al., 2019). For last few decades, climate change becomes a serious threat to agriculture in context to influence crop and livestock production, hydrological balances, input supplies and other components of agricultural system (Kabir, 2015; Kumar and Kumar, 2016). Agriculture is inherently sensitive to climatic conditions and conservation agriculture may be the only answer to combat the negative impact of climate change.

Overview of the Indian Dairy Sector

India’s dairy sector occupies a unique global and domestic position due to its scale and socio-economic impact. As the world’s largest producer of milk with 230.6 million tonnes of production in 2022-23 (BAHS, 2023), India contributes approximately 23% of global milk production, surpassing countries like the United States and New Zealand (FAO, 2020). This dominance is largely attributed to Operation Flood, the revolutionary initiative launched by National Dairy Development Board (NDDB) in the 1970s, which transformed India from a milk-deficient country to the world’s largest milk producer (World Bank, 1998). Operation flood is known for its contribution in increasing milk production, supplement rural income and make available reasonable prices to the consumers. This initiative laid the foundation for the cooperative model of dairy production, epitomized by the success of organizations like Amul, which became a global model for dairy development (Candler & Kumar, 1998).

1. TYPES AND GRADES OF IMMUNITY

The immune response, which has inherited the character of memory, as evinced by rapidity and specificity of the responses on the second exposure to antigen, was cleared the minds of scientists especially bacteriologists who could find certain cells especially lymphocytes to play a major role in immune response.
 
The fact that the blood also contains soluble protective substances both heat stable which were later known as antibody and heat labile, later called as the complement system. These two were regarded as totally separate phenomenon in the beginning years. Eventually the distinctions between specific and non-specific responses were understood.
 
There are two types of immunity
    i)    Non-specific (Innate, natural or native) immunity
    ii)    Specific (Acquired) immunity.

A. Answer the following

Q.1.    What is the difference between apoptosis and necrosis?

Ans.    In apoptosis, there is pronounced decrease in cell volume, modification of cytoskeleton, condensation of chromatin and degradation of DNA into fragments. Due to these changes, an apoptotic cell sheds tiny membrane bound apoptotic bodies containing intact organelles. Macrophages phagocytose apoptotic bodies and cells in the advanced stages of apoptosis. But there is no release of proteolytic and the lytic enzyme, cationic proteins and oxidizing molecule in the surrounding tissue and no local inflammatory response. On the other hand, in necrosis cells swell and burst releasing their contents and possibly triggering a damaging inflammatory response.

Predominantly, an agrarian society is mostly dependent on the farm sector. Agriculture plays an important role in Indian economy notwithstanding its shrinkage in share in the gross domestic product (GDP) of the country being 55.4% in 1950-’51 and 17.4% in 2018-’19 (Tripathy, 2019). Still the agriculture and allied sector is providing employment to 54 percent of the Indian population.

1.1 Introduction

Poultry is one of the fastest-growing areas of India’s agricultural industry, with an annual growth rate of around eight percent. Over a span of four decades, the chicken industry in India has seen a paradigm shift in structure and operation, transforming from a simple backyard occupation to a significant commercial agri-based enterprise. Constant efforts in upgrading, modifying, and using new technologies opened the path for the multiplication and diversification of poultry industries. The expansion is not just quantitative, but also qualitative, sophisticated, and productive. This transition has necessitated substantial expenditures and increases in breeding, hatching, raising, and processing. The rise of the poultry industry in India is also characterised by the expansion of chicken farms.

To fully explore the history of medical and drug development, it would be necessary to go back as early as 13,000 BCE, where drawings on the Lascaux caves in France suggest that humans were using plants for medicinal purposes. Since then, medical traditions have evolved and dissolved across societies all over the globe. Natural products including plants, animals and minerals have been the basis of treatment of human diseases. The last two centuries have seen a focus on scientific medicine, with a focus on drugs whose effects that have been proved by the scientific method. Yet given this setting, many of the major pharmaceutical corporations have renewed their strategies in favor of natural product drug discovery. Numerous drugs have entered the international pharmacopoeia via the study of ethnopharmacology and traditional medicine. At this point in history, it is possible for both traditional and western medicine to benefit from collaboration between the two disciplines. For traditional medicines, newer guidelines of standardization, manufacture and quality control and scientifically rigorous research on the scientific basis for traditional treatments will be required. In return, traditional medical traditions can offer a more holistic approach to drug design and myriad possible targets for scientific analysis. Powerful new technologies such as automated separation techniques, high-throughput screening and combinatorial chemistry are revolutionizing drug discovery. Traditional knowledge can serve as powerful search engine, which will greatly facilitate intentional, focused and safe natural product drug discovery and help to rediscover the drug discovery process. By looking at the historical trends in drug and medical developments, it is possible to understand how current drug development will benefit from this partnership.

Metagenomics is a relatively new field that combines molecular biology and genetics in an attempt to identify, and characterize the genetic material from environmental samples and apply that knowledge. The genetic diversity is assessed by isolation of DNA followed by direct cloning of functional genes from the environmental sample. But more importantly, it is extremely beneficial in the study of synthetically made genomes. Metagenomics is described as “the comprehensive study of nucleotide sequence, structure, regulation, and function”. Scientists can study the smallest component of an environmental system by extracting DNA from organisms in the system and inserting it into a synthetic model organism. The model organism then expresses this DNA where it can be studied using standard laboratory techniques. The development of metagenomics stemmed from the ineluctable evidence that as-yet-uncultured microorganisms represent thevast majority of organisms in most environments on earth. This evidence was derived from analyses of 16S rRNA gene sequences amplified directly from the environment, an approach that avoided the bias imposed by culturing and led to the discovery of vast new lineages of microbial life.

Metagenomics is employed as a means of systematically investigating, classifying, and manipulating the entire genetic material isolated from environmental samples. This is a multi-step process that relies on the efficiency of four general steps as shown in the diagram. The procedure consists of: the isolation of genetic material, the manipulation of the genetic material, library construction, and the analysis of genetic material in the metagenomic library. Metagenomics provides a second tier of technical innovation that facilitates study of the physiology and ecology of environmental microorganisms. Novel genes and gene products discovered through metagenomics include the first bacteriorhodopsin of bacterial origin; novel small molecules with antimicrobial activity; and new members of families of known proteins, such as an Na⁺(Li⁺)/H⁺ ant porter, RecA, DNA polymerase, and antibiotic resistance determinants. Reassemblyof multiple genomes has provided insight into energy and nutrient cycling within the community, genome structure, gene function, population genetics and micro heterogeneity, and lateral gene transfer among members of an uncultured community. The application of metagenomic sequence information will facilitate the design of better culturing strategies to link genomic analysis with pure culture studies.

Introduction There is an emergence of a transformative paradigm of participatory approaches in various fields such as management, health care and education, community development, etc. Participatory approaches challenge the top-down approach used frequently for decision making (Narayanasamy, 2009). Participation is a dynamic process where two individuals exchange their ideas, thoughts, and knowledge for making proper decisions and solving the problems faced by local people. It is a process of empowering individuals that helps people make proper analysis, make their own decisions, and develop their confidence. It is successfully used in increasing self-help activities of local people and for proper implementation and evaluation of large scale projects. FAO has reported that through participatory programmes it is very easy to mobilise local knowledge for self-reliant development, reducing government assistance costs.

What is seed?

“A seed is an embryo, a living organism securely fixed in the supporting or the food storage tissue.”

A true seed is defined as “Structurally a true seed is a fertilized matured ovule, consisting of an embryonic plant, a store of food and a protective seed coat, a store of food consists of cotyledons and endosperm”. In broad sense, “seed is a material which is used for planting or regeneration purpose”. Scientifically, “seed is a fertilized matured ovule together covered with seed coat is called seed” or “it is a propagating material i.e., part of agriculture, sericulture, silviculture and horticultural plants used for sowing or planting purpose”.

The business of Seed Technology is to protect this biological entity and look after its ‘welfare’, while the focus of Food Technology is on the second component – the supporting tissue.

Introduction Surimi and surimi based seafoods are traditional products of Japan and occupy an important position in the dietary culture of the country. Today, the largest producers of surimi are the United States, Japan and Thailand. Surimi is also manufactured in China, Vietnam and Malaysia. The process of makingsurimi originated in Southeast Asia and was further developed in Japan in the 16th century. Surimi is a product of Japanese origin, derived from a traditional Japanese way of using and preserving fresh fish. The word ‘surimi’ comes from the Japanese words ‘suru’ meaning ‘to process’ and ‘mash/mi’ meaning ‘meat’. Technically, surimi is the stabilized myofibrillar protein which is obtained by mechanically deboned fish flesh, which is washed, mixed with cryoprotectants, and stored frozen. Washing not only removes fat and undesirable matters such as blood, pigments and odoriferous substances but also increases the concentration of myofibrillar protein. A fish-based product serving the raw material for preparation of analog of seafoods like crab, lobster, scallop & other shellfish.

Introduction

Parvoviruses are nonenveloped, single-stranded DNA viruses belonging to the genus Protoparvovirus, member of the Parvoviridae family, that has been included within the species Carnivore protoparvovirus 1, together with Feline panleukopenia virus (FPV), Mink enteritis virus (MEV) and Raccoon parvovirus (RPV), according to the International Committee on Taxonomy of Viruses (Tijssenet al 2011). Two distinct parvoviruses are known to infect dogs—the pathogenic CPV 2 and CPV-1 or the minute virus of canine (MVC). CPV-2, the causative agent of acute hemorrhagic enteritis and myocarditis in dogs, is one of the most important pathogenic viruses with high morbidity (100%) and frequent mortality up to 10% in adult dogs and 91% in pups. CPV-2 is the etiologic agent of a contagious disease, mainly characterized by clinical gastroenteritis signs in younger dogs. This virus that causes the disease “parvo”, first emerged among dogs in Europe around 1976. By 1978 the virus had spread unchecked, causing a worldwide epidemic of myocarditis and inflammation in the intestines (gastroenteritis) and could infect domestic dogs, spreading in the global dog population within 2 years. This original type, was rapidly replaced by two antigenic variants, types 2a and 2b (Parrish et al 1985, 1991), and in 2000 a third type CPV-2c was detected (Buonavogliaet al 2001). Canine parvovirus (CPV) is responsible for acute gastroenteritis in pups, with a high rate of mortality (Carmichael and Binn, 1981). We now know the virus is not limited to dogs, but is capable of causing infections in wild canines such as coyotes and wolves, and other wild animals, including foxes, raccoons and skunks. Since its emergence in 1978, it was and remains a common and important cause of morbidity and mortality in young dogs.

Introduction

The food problem in the world is expected to become more serious if the world population keeps growing at the present rate. Out of various strategies to solve the problem, the post-harvest handling of the grains is of paramount importance. Tribolium species is major pest of stored grain and grain products in the tropics. Control of this insect relies heavily on the use of synthetic insecticides, which has led to many problems such as increasing costs of application, pest resurgence, pest resistance to pesticides and lethal effects on non-target organisms in addition to direct toxicity to users and disturbances of the environment. Thus, insecticides of natural origin are rational alternatives of synthetic insecticides. Several botanicals, natural products and their derivatives have been reported and exhibit better efficacy and potency against the stored grain pests.

In the present investigation, an attempt has also made to test ovicidal, larvicidal and adult emergence suppression potentials of the extracts of some of the locally available Indian medicinal plant viz., Datura stramonium, Ricinus communis, Vitex trifolia and Nerium indicum against T. castaneum against T. castaneum, commonly called as Red flour beetle.

ABSTRACT

Papaya (Carica papaya L.) is an important crop in the tropics and subtropics for export of fruits and above all, for local consumption. Cultivation of papaya faces with problems due to its heterozygosity, dioecious nature and susceptibility to a large number of viral diseases. Crossing between two hermaphrodites will produce the highest ratio of fruit bearing female trees, which is of homozygous dominant andromonoecious types which are always letha l due to po st fertilization barriers leading to their abortion. The gynodioecious varieties of papaya have the M1M1 forms while selfing and hence for explant selection , gynodioecious varieties like Sunrise solo and CO7 were prefered Embryo culture is one of the earliest forms of in vitro culture applied to solve practical problems and is probably the tissue culture techniques that has proven of greatest value to breeders. Ovule culture is practised in a case when small (or) young embryos that abort at early stages of development and are difficult to isolate. This necessiates the development of a protocol for initiation, multiplication and regeneration of ovular callus of papaya.
