Biodiversity in flora and fauna is the wealth of any nation. Billions of genes with considerable value are habitated in the bioreserves designated. Genetic resources are the backbone of crop improvement in horticulture. Term ‘genetic resources’ was coined by Sir Otto Frankelin 1967 to highlight germplasm as natural resource for improvement of crop plants. The Consortiumof International Agricultural Research Centers (CGIAR) established in 1971 by United Nations Development Programme (UNDP) is a consultative group to support a network of 16 international agricultural research centres. It controls world’s largest collection of genetic resources of more than 6 lakhs of accessions of over 3,000 crops, forage and pasture species (both cultivated & wild). International Bureau of Plant Genetic Resources (IBPGR, 1974 now Biodiversity International)
situated at Rome, Italy had become the International Plant Genetic Resources Institute (IPGRI) in October, 1991 for collection, evaluation & conservation of germplasm for future use. IPGRI began independent operation as one of the Centres of CGIAR in 1994. Today, Biodiversity International is the only global research-for-development organization that investigates the conservation and use of agricultural and forest bio-diversity. It is in the forefront of assisting member countries in identifying genetic resources for nutritional and food security without hampering the fragile ecosystem.
Biodiversity of given region is assessed in terms of species richness. It boosts ecosystem productivity where each species, no matter how small, all have an important role to play. Plant Generic Resource (PGR) is fundamental to crop improvement programme and the key to establish future food and nutritional security. The 1st plant genetic resources centre of the world was situated at Leningrad, Russia. Later in McNeely et al. (1990) categorized India as one of the 12 mega biodiversity countries in the world and paved the way for its placement on the world’s conservation map. Myers (2000) identified global bio-diversity hotspots and North East parts of India are the 2nd largest and next only to Mediterranean basin among the 25 identified globally.

Abstract

The Directorate of Sorghum Research has explored 9 states for sorghum germplasm during 2000 – 2011. The sorghum landrace collections are mostly named with the village name prefixed to the landrace (ex. tongraligaon maldandi, sultanpur maldandi etc), landraces are also named based on the grain colour (ex. tella jonna, bili jola etc.) and size (ex. moti rabi jowar), ear head compactness (ex. mudda jola), use of the stem, ear head or grain (ex. dagdi, gundu, allur, broom etc.) for varieties utilities. The landraces are being grown by farmers over the years for many reasons. The moli jowar grains are attractive and fetch higher price in the market compared to other released varieties in Madhya Pradesh. Some are used for specific food preparations. The irungu cholam flour is boiled with water to prepare food. The mathappu cholam is used to prepare a jelly like food known as khali in Tamil Nadu. The beed maldandi and bidri from Maharashtra are used to make quality jowar roti. Karnataka’s kodumurugu jola and allina jola are used to make laddu’s and pappads respectively. Broomcorn jowar from Uttarakhand are used for roti, cattle and poultry feed making. The allur jola from Karnataka is used to prepare allu dish during the nagapanchami (festival of snake god). The pachcha jonna from Andhra Pradesh, barmuda local, deshi chari and gudli local from Rajasthan and bendri dagdi and khondya from Maharashtra are very good fodder types. Valsangh maldandi local, Vadgaon dagdi maldandi, tongraligaon maldandi, tongraligaon dagdi, sultanpur local dagdi, sultanpur maldandi, harni jogdi (dagdi), harni jogdi, chungi maldandi, musti local (Maldandi), chungi kuch-kachi, baddi jowar, chakur maldandi from Maharashtra, and sai jonna from Andhra Pradesh are considered by the farmers as drought tolerant landraces. In Andhra Pradesh, Koya’s (tribe) grow konda jonna. Lambada’s used to grow the maghi sorghum landraces extensively in the state. The tribal community mainly uses the accessions as food and some are used for both food & fodder. The accessions collected from the higher elevation and remote forest area is source material for pest & disease resistance. The accession IC 347574 is used as the tribal food. The accession IC 347583 is a guinea race and IC 347585 is a durra-guinea race sorghum collected at an elevation of 500 feet from the tribal village. In Gujarat,Gomati (tribe) grow deshi jonna landraces. In Madhya Pradesh, Rewa district is the maximum deshi jowar cultivation region. This area is commonly called “Junariwala Shetra”. Mehran, Swarguor, and Kushwaha are the main tribes cultivating the jowar in these regions. In Maharashtra, Korukoo’s tribe grows somgi and deshi jonna landraces. They cultivate sorghum with lablab, chillies, cotton, redgram, and tomato at the height of 650 – 870 m from MSL. Maximum diversity of the sorghum still exists in the disturbed forests. Due to extend of its natural variability, India exists as the secondary origin of sorghum.

Meeting food demand and escalating food prices are serious issues, as current food scenario indicate that crop demand will increase by 100 to 110% from 2005 to 2050 at global level (Tilman et al., 2011). Precision use of fertilizer is the crucial for achieving sufficient food production for growing population. It is costly input to produce and apply, both financially and environmentally. Fertilizer consumption measures the quantity of plant nutrients used per unit of arable land.

Life on Earth is rooted in soil. Soil is not just a substratum anchoring the plants and giving a base for all terrestrial animals. It is the largest terrestrial ecosystem, and one of the most wonderful ecosystems on Earth. It inhabits most microorganisms. Microbial populations flourishing within the soil have greater biomass than all the human beings, elephants, and whales put together. It is due to the microorganisms that the soil constitutes the most active ecosystem on Earth.

The health of the soil is crucial for the health of all the plants growing on it and for all the animals dependent on it for their inhabitation and nourishment. Soil health is also critical for the well-being of numerous microorganisms, detritivores, and several other organisms. Soil is composed of all essential nutrients/ minerals, air, water, and organisms in a proportion that strikes its ecological balance and maintains its structure and functions revealed through its productive potential.

Soil, like all other ecosystems, is itself a dynamic ecosystem. Its composition keeps changing but natural inbuilt mechanisms help strike a balance and recover 

12.1 What are Botanical Gardens?
Botanical gardens are the institutions that maintain the living plant collections of different varieties of plants, including the ornamental and cultivated ones, wild, medicinal, of economic importance, of various geographical regions, of special interest, etc. They are of value not only to the botanists, horticulturists and foresters but also to the millions of tourists
A big botanical garden contains plant species from several corners of the globe. It also includes green houses, a library, a herbarium, research laboratories, and several miscellaneous resources including photographs, paintings, illustrations, reprints, note books, and specimens of several types. It is, therefore, not merely a garden but a botanical institution.
Modern botanical gardens serve as centres for documentation, research, reference, data storage, education, conservation, and several other biological facilities to mankind.At present, there are over 600 botanical gardens in the world.

Introduction

Livestock plays an important role in the sustainable livelihood of poor people of rain-fed agro-ecosystem, because of inherent risk involved in the crop farming due to uncertainty of rainfall and occurrence of recurrent droughts. They provide income and increased economic stability, and often the most important “cash crops” in small-scale mixed farming systems. Livestock sector in India is highly livelihood intensive and most rural households own livestock of one species or the other and earn supplementary incomes from them. Livestock holding is less iniquitous than land holding and income from livestock is more equitably distributed. The sector contributes 25.6 per cent of the value of output at current prices of total value of output in agriculture, fishing & forestry sector and in GDP, it was 4.11% in 2012-13 (19^th livestock census, 2012) therefore, development of the livestock sector is the critical pathway to rural prosperity

As per the 19^th livestock census, the total livestock population consisting of Cattle, Buffalo, Sheep, Goat, Pig, Horses & Ponies, Mules, Donkeys, Camels, Mithun and Yak in the country is 512.05 million numbers in 2012. The total Bovine population (Cattle, Buffalo, Mithun and Yak) is 299.9 million numbers in 2012 which shows a decline of 1.57% over previous census. In percentage basis distribution of livestock were: 37.28% were cattle, 21.23% buffaloes, 12.71% sheep, 26.40% goats and 2.01% pigs. The corresponding figures as per the 18th Livestock Census were 37.58%, 19.89%, 13.50%, 26.53% and 2.10%. The number of milch animals (in-milk and dry) in cows and buffaloes has increased from 111.09 million to 118.59 million, an increase of 6.75%. The number of animals in milk in cows and buffaloes has increased from 77.04 million to 80.52 million showing a growth of 4.51%. The Female Cattle (Cows) Population has increased by 6.52% over the previous census (2007) and the total number of female cattle in 2012 is 122.9 million numbers. The Female Buffalo population has increased by 7.99% over the previous census and the total number of female buffalo is 92.5 million numbers in 2012. The buffalo population has increased from 105.3 million to 108.7 million showing a growth of 3.19%. The total sheep in the country is 65.06 million numbers in 2012, declined by about 9.07% over census 2007. The Goat population has declined by 3.82% over the previous census and the total Goat in the country is 135.17 million numbers in 2012. The total poultry population in the country has increased by 12.39% over the previous census and the total poultry in the country is 729.2 million numbers in 2012. The total number of animals in milk in the country is 116.77 Million numbers.

Precision farming is also known as precision agriculture. A farmer is not only expected to produce more for the increasing population and his family but save and protect the fragile environment while practicing it. Advanced technologies with appropriate and exact inputs such as precision farming can take care better of environment. Precision farming is right farming operations at right time leading to maximize profit. Every farming activity performed with precision by doing the right thing, in the right place, in the right way, at the right time and with right technology leading to maximize profit is known as precision farming. It is an efficient, eco-friendly and accurate management of agriculture inputs such as water, seed, fertilizers, pesticides and harvesting tools and machinery to maximize profit and reduce waste. The basic concept of precision farming is to match agricultural inputs and operations as per crop (variety/hybrid/cultivar) and agroclimatic conditions with accuracy to their better use efficiency. Perfection (nothing requisite is wanting) in farming is the key to precision farming.

Precision farming is based on global positioning system (GPS). The unique character of GPS is precision in time and space. Its use is spreading to all farm operations. Precision farming is an integrated information and production based farming system that is designed to increase long term, site specific and whole farm production efficiency, productivity and profitability while minimizing, waste and unintended impacts on the environment. This concept of precision agriculture is based on observing, measuring and responding to inter and intra field variability in crops.

Farm management strategy is the key to precision agriculture that uses integrated smart technologies such as sensors, GIS, GPS, satellite radars, drones, IoT (Internet of things) and data analytics to develop informed crop production and management decisions. The field variations are precisely measured with the help of technologies to optimize applications of inputs such as manures, fertilizers, pesticides, bio-agents and water use to increase crop yield at minimum cost. The aim of precision farming is to increase productivity, decrease production costs and minimize the environmental impact of farming.

A sound is a form or energy. Therefore, it has to have an impact on life in one way or the other. Most of the organisms of Kingdom Animalia communicate with each other creating a peculiar sound. Creating sound is inevitable for performing various life activities. Every animal species has the characteristic sound it reflects through its behavior. Whatever all the animals communicate through creating specific sounds is all-natural. Nature, as such is a stupendous repository of a diversity of sounds, all being specific characteristics of life.

Human behavior, however, is highly evolved in terms of creating a variety of sounds. Communication, entertainment, and many behavioral activities are expressed through creating distinctive sounds. There is a difference between natural sounds and the ones human beings create or can create. Humans often generate sounds, not just in a natural manner, but also with various technical aids, that often become unpleasant what we call noise. Creating noise, or noise pollution, seems to be an exclusive characteristic of the human species. Of course, there could be some natural sounds that might occasionally cause havoc to life. Examples are the sounds generated at the time of the volcanic eruption, during an earthquake

Introduction

Fruits and vegetables are essential constituents of daily diet and are highly demanded in the recent years from most of the population. They are reservoir of vitamins, essential minerals, antioxidants, bio-flavonoids, dietary fibres and f lavour compounds which fall easily victim to abiotic and biotic adversities. Fruits and vegetables are highly perishable and during the post- harvest, there are considerable losses due to microbes, insects, respiration and transpiration.

The important quality factors of fresh produce contributing to the marketability are texture, colour, appearance, flavour, nutritional value and microbial safety. These quality factors are measured by plant variety, ripening stage, maturity stage pre-harvest and post-harvest conditions. The Post-harvest losses of fruits and vegetables are a serious problem because it rapidly deteriorates them during handling, transport and storage. Edible coating over fruits and vegetables are used to improve their quality and shelf life.

Lipids are a class of organic compounds composed of hydrogen (H), carbon (C), and oxygen (O) atoms. These classes of biomolecules come together to create the fundamental building blocks that shape and govern the structure and functionality of living cells. The term lipid was used by the German biochemist Wilhem Bloor in 1943. Lipids are heterogeneous groups of substances that are insoluble in polar (water) and soluble in non-polar (ether, benzene, and chloroform) solvents. Lipids are the esters of fatty acids and their derivatives. Lipids play a crucial role in both the plant and animal domains. They are widely distributed in plants, but lipids are primarily stored in animal adipose tissues.

Classification of lipids

Lipids are classified into four different groups, as shown below:

1. Simple lipids

2. Complex lipids

3. Derived lipids and

4. Miscellaneous lipids

ABSTRACT

The popular use of local plant wealth among the rural people in Hamirpur district of Himachal Pradesh reflects their greater interest in the traditional medicine and other traditional and commercial purposes. Hamirpur, one of the pioneer Himalayan district is a rich repository of medicinal flora. It is the smallest district of Himachal Pradesh due to its area, surrounded by thick forest area which is rich in diverse vegetation. Medicinal plants are used in the Ayurvedic, Unani and other traditional systems of medicine and in plant-based pharmaceutical industries. The patterns of the use of the local medicinal herbs for the treatment of various diseases and ailments have been an old practice. But the people of the district still depends upon the uses of local plants for their primary health problems treatment. This paper provides the information on the traditional uses of some of the plants such as Asparagus racemosus, Acacia catechu, Albizzia lebbek, Berberis lyceum, Bryonia laciniosa, Azadirachta indica, Adhatoda vasica, Andographis peniculata, Aegle marmelos, Celastrus peniculata, Cymbopogon flexsosus, Cuscuta reflexa and Holarrheana antidysentric of Hamirpur district for the treatment of various disorders such as anthelmintic, anti-fungal, diabetic, antibacterial, cancer, diarrhea, bronchitis, tuberculosis etc. Hence the objective of the study was to document ethnobotanical knowledge primarily of notable herbs employed by the different backward people, whether tribal or rural, in the area under study. Therefore the documentation and recording of traditional knowledge associated is necessary step for the preservation of traditional knowledge about the use of local plant wealth and conservation of plant species of study area. The data would be useful for further scientific exploration.

The increasing awareness of the deleterious effects of indiscriminate use of chemical fertilizers and pesticides in agriculture has led to the adoption of organic farming as an alternative method for conventional farming world-wide. It is gaining gradual momentum across the world and the growing awareness of organic food which is emerging as an attractive source of rural income generation especially in integrated farming systems.

In north west India where rice-wheat, cotton-wheat and pearl millet-wheat cropping systems are most prevalent. But now, these cropping systems are not proving farmers’ friendly due to higher water requirement, declining yield, susceptibility to insects and pests and adverse effect on soil health. Moreover, in the new millennium with the growing demand of agricultural commodities in national as well as international market due to ever increasing population and globalization, Indian farmers are forced to produce higher quantum of quality agricultural commodities at low cost from shrinking land and natural resources.

Mungbean - wheat cropping system requires less water and hence, can be grown in areas where water availability is limited in addition to beneficial effect of mungbean to supply N to the succeeding wheat crop which are favorable for organic farming. Wheat (desi) also known as tall wheat requires less water and is very responsive to low doses of nutrients. The dwarf wheat grown by farmers with the application of chemicals in the form of fertilizers, weedicides, insecticides and pesticides is not preferred by people and therefore, the demand of organic wheat is rising fast in national and international market. This cropping system can be taken successfully in farming systems for higher monetary returns.

There is need to shift a portion of cultivable land with organic farming as an alternate practice technique. Organic farming gives emphasis on sustainability, environmental safety and low cost production techniques over chemical farming. Keeping the issues of 21^st century agriculture in view following aspects also shows importance of organic farming: Reduce the toxic load; keep chemicals out of the air, water, soil and our bodies; reduce if not eliminate off farm pollution; protect future generations; build healthy soil; taste better and truer flavor; assist farmers of all sizes; promote biodiversity; celebrate the culture of agriculture etc.

Radioactive pollution is largely attributable to radioactivity, a natural property of certain elements, such as radium, uranium, thorium, etc. of spontaneously emitting protons (alpha particles), electrons (beta particles), and gamma rays (short-wave electromagnetic waves) through the disintegration of their atomic nuclei (nuclides).

An alpha particle consists of two protons and two neutrons, which is akin to a helium nucleus. Alpha particles travel at a very slow speed, whereas gamma rays propagate at the speed of light. The alpha particles have less penetration power than the beta and gamma rays. In human tissues, alpha particles can penetrate up to a depth of about 0.005 to 0.008 cm. The gamma rays, on the other hand, are the most penetrating and can easily pass through a human body without striking anything in between. The high penetration power of gamma rays is because they have no charge; therefore, they do not interact with anything as the charged alpha particles would do

Amino acids are organic molecules made up of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). However, sulfur (S) and selenium (Se) are also found in some cases. Amino acids are essential organic compounds that come together to create proteins, thus making them the fundamental building blocks of proteins. These biomolecules play vital roles in various biological and chemical processes within the human body and are essential for the growth and development of an individual.

Amino acids consist of an acidic group (-COOH), a basic group (-NH2 ), and a side chain (R) or a hydrogen (H) atom, all bonded to the carbon atom. The features of amino acids are due to the side chain because they differ only in their side chain. All amino acids have the same basic structure except proline, which has a cyclic structure.

Various forms of amino acids like alpha (α), beta (β), gamma (γ) or delta (σ) form are found. The position of the amino group (-NH2 ) determines the form of the amino acid, i.e., if the NH2 group is attached to the α-carbon, it is called α-amino acid; if β-carbon, it is called β-amino acid, and so on. Mostly, α-Amino acids are found as the numbering of amino acids is done from the carboxylic group (-COOH).

Pineapple (Ananas comosus) is an edible fruit bearing plant native to South America belonging to family Bromeliaceae. Pineapple is grown over an area of 1.06 million hectares with an annual production of 29.36 million metric tonnes (FAO, 2022). Pineapples are rich in vitamin C, minerals, fiber and low in calories. The enzyme bromelain present in pineapple is of considerable importance to the pharmaceutical and cosmetic industry (Varilla et al., 2021). The market for pineapples has been expanding significantly because of its appealing aroma compounds and nutritional benefits. The climate and distribution of rainfall in tropical and sub-tropical regions make these areas ideal for pineapple cultivation. Worldwide, Brazil is the leading producer of Pineapple followed by Philippines, Thailand, Costa Rica and India (FAO, 2022). In India the leading pineapple producing states are West Bengal, Northeastern region, Bihar, Kerala, Karnataka, Goa, and Maharashtra.This ‘Kew’ of Cayenne group and ‘Mauritius’ of the rough leaf Queen group are the two varieties dominating in India (Devi et al., 2013; Joy and Sindhu, 2012).

Botanically, Pineapple is a herbaceous perennial having short stem and tough waxy leaves. It produces a fleshy, edible, yellow fleshed which is a fusion of 100-200 berry like fruitlets. Most of the members of Bromeliaceae family are epiphytes i.e. grown on rocks and living trees though pineapples grow on the soil bearing sensitive adventitious root that cannot regenerate once damage and intolerant to poor soil aeration. The cultivated varieties of pineapple can be categorized into three groups namely, Cayenne, Queen, and Spanish. The Spanish and Cayenne groups can be cultivated for dual purposes viz. fresh fruit and canning. However, the Queen group are only cultivated for fresh fruit markets due to the presence of deep eyes making it unsuitable for canning (Devi et al., 2013).

Ultrasound is important tool for diagnosis and research that can be compared with other tools like radio-immunoassays. This has become an important tool applicable to farm and pet animals. Ultrasound uses high-frequency sound waves to produce images of soft tissues and internal organs. Electric current is applied to crystals in the transducer, producing vibrations characteristic of the crystals and resulting in sound waves. The sound beams that pass through the tissues are quite thin and a thin “slice” of tissue is sampled. The two dimensional image produced by ultrasound resemble to histological section. The sound waves are propagated or reflected by various tissues in different ways depending on their thickness and composition. The transducer receives those reflections and converts into electric signals and produces an echo on the ultrasound screen. Grey - scale is the term used for monochrome monitors on which a number of grey shades are distinguishable between black and white and constitute the image of reflected portion of tissue. Non-ecogenic (non echoic) tissues like fluids do not reflect sound waves and appear black on the screen. The echogenic tissues, having dense consistency, appear white as they reflect most portion of sound beam. Sometimes the artifacts create problem in the real image of the organ. These artifacts are created by certain tissues that cause bending or back and forth bouncing or blocking of sound beams. For imaging the reproductive tract of the domestic animals, B-mode (brightness modality), real time scanners are used. The amplitude of returning beams is reflected in the brightness of the dots on the screen. B-mode modulates brightness of the dots or pixels on the screen of echo displayer. The echo signals are presented as brightness of pixel corresponding to the amplitude of signal. The picture should be adjusted for clear display. In B-mode display the time-base brightness should be reduced just below the threshold of visibility so that even the smallest echoes could be visible.
