Tree leaves serve as a traditional source of roughage for livestock such as sheep, goats, cattle, and buffaloes. During the initial growth phases, these leaves exhibit a relatively high crude protein percentage alongside lower fiber content. However, as the tree matures, there is a notable decline in protein levels and a corresponding increase in crude fiber content. Generally, tree leaves are abundant in Ca, often containing two to three times the amount found in cultivated fodder, but they are deficient in phosphorus, leading to an imbalanced Ca to P ratio. The presence of tannic acid further reduces the digestibility of the protein found in these leaves. The dry matter content of most tree leaves typically falls within the range of 30-40%, accompanied by a significant protein concentration. Although the crude fiber percentage in tree leaves is lower than that in grasses and hays, their digestibility remains poor due to the tannic acid content. Additionally, while the ether extract in tree leaves is relatively high, it is often less digestible compared to that found in cultivated fodder.
Leguminous trees and shrubs
Animals that graze on mature grass pastures frequently enhance their diet by consuming the leaves of trees and shrubs, many of which belong to the legume family. The term ‘browse’ refers to the food obtained in this manner; in addition to being consumed directly by animals, browse can also be harvested and transported to livestock kept in enclosures. The leaves of leguminous trees are notably rich in protein (200 300 g/kg DM) and minerals, although they also contain a significant amount of fiber (50 60% neutral-detergent fiber/DM). The presence of tannins and potentially other compounds can reduce the palatability of browse, suggesting that its nutritional value may serve as a reserve food source for times when grass is no longer accessible. A prominent example of a browse species is leucaena (Leucaena leucocephala), commonly referred to as ipil-ipil, which is an important tropical legume widely cultivated across various regions. It serves as a significant source of protein and minerals and is abundant in β-carotene. However, it also contains the toxic amino acid
mimosine. Other notable leguminous forages include Gliricidia (Gliricidia sepium), Sesbania (Sesbania sesban) and Acacia (Acacia angustissima).

9. The outward pressure exerted by the cell solution on the cell wall which is developed due to osmotic diffusion of water is called as_____________. (Turgor pressure)

Trees that provide materials for propagation are called mother trees. Selection of mother trees is important because the young trees will be expected to inherit the favourable characteristics from the mother tree, such as fast growth, upright or spreading shape of the tree crown, good flowering and fruiting, and tolerance of diseases or pests. There may be sexual propagation by seed or vegetative propagation by using other parts of the tree. The genetic make-up of the seeds differs due to recombination of the genes, resulting in seedling variation. Thus, all the seedlings may look like the mother tree in some respects, but no two seedlings are the same. In case of vegetative propagation through cutting, layering, grafting or budding, the genetic make-up of the young tree is exactly the same as that of the mother tree. Consequently, all new trees grown vegetatively from one mother tree have the same set of gene pairs and therefore the same characteristics; they form a so called clone. Differences between plants of a clone can only be caused by different growing conditions.

Myristica fragrans Houtt., the nutmeg tree is unique among spice plants as the donor of two distinct spices; nutmeg and mace.Native of Indonesia (Moluccas islands), nutmeg tree grows there abundantly and is now naturalised in West Indies, Srilanka, India, Phillipines, Tropical America and Pacific Islands. (Varghese, 2000). In India, the plant is grown in certain pockets of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra, North East India and Andamans (Krishnamoorthy, 2000). It is also grown in a small scale in Srilanka, Trinidad, China, Tobago, Zanzibar and Mauritius.

Tree tomato belongs to the family solanaceae, genus Cyphomandra and species betacea. The Cyphomandra genus is made up of about 30 species. Shaw (1996) has reported that Cyphomandra genus consists of 35 species confined to the New World tropics. They were earlier described under the genus Solanum. They can be separated from Solanum  by several characters, the most important being anther characters. In Cyphomandra in the anther the connective is thickened and expanded dorsally. As a result, it is clearly differentiated from the anther thecae, which is thin walled and papillose.

Economically important plant in this genus is Cyphomandra betacea. Other important related species are Cyphomandra casana (Casana), C. craccifolia (Mountain tomato) and C. fragrans (Guava tamarillo). It has got distant affinity with Lycopersicon esculentum (Tomato), Physalis ixocarpa (Tomatillo), P. peruviana (Cape gooseberry), Solanum muricatum (Pepino Dulce) and S. sessiliflorum (Cocona).

The tree tomato is a bushy fruit plant which in early time was planted in the gardens high upon the mountain slopes. Presently in India, Sri Lanka and number of other countries it is grown in the hilly region. Indians of Peru at very early stages gave the world a number of food plants of which potato is of great value, and tree tomato in the only woody species of family Solanaceae. The tree is fast growing and starts to bear in about two to three years times. The egg shaped and usually smooth-skinned fruits are produced in large number in hanging clusters. The sub acidic and succulent fruits are agreeable and eaten as raw. In central America it is called tomate and cultivated at an elevation of 4000 to 8000 feet. The crop loves rich loamy soil and grows best under irrigated conditions.

Natural farming integrates traditional wisdom with ecological sustainability by using on-farm resources, avoiding synthetic inputs, and enhancing biodiversity. Within this framework, tree-based and multi-tier farming systems play a pivotal role in optimizing land use and ensuring environmental balance. These models are especially beneficial for small and marginal farmers in India’s varied agroclimatic zones, offering resilience, productivity, and sustainability.
Tree-based farming incorporates fruit or timber trees—like mango or guava— intercropped with pulses, vegetables, and herbs. This mimics forest ecosystems where diverse species coexist, supporting one another. Trees improve soil quality through leaf litter, reduce erosion, and help conserve moisture. Their canopy creates favorable microclimates for understory crops.
Multi-tier systems structure crops by height: tall trees form the top layer, followed by medium-height plants such as papaya, bushy crops like chillies, and ground-level creepers such as pumpkin. This vertical arrangement maximizes sunlight use and space efficiency, improving overall yield per unit area.
These systems enhance soil fertility, promote nutrient recycling, and reduce crop vulnerability to pests and climate extremes. Practices like mulching, intercropping, and the use of Jeevamrit and Beejamrit are seamlessly integrated, reinforcing soil health and sustainability. Together, they offer a regenerative, income-diversifying strategy for natural farmers across India.

Introduction 
Tree-based biofuels, which are made from non-edible oilseeds of perennial trees, have emerged as a renewable energy source with considerable environmental and economic benefits. Unlike annual biofuel crops, tree-based biofuels have the potential for long-term yields, soil conservation benefits, and the ability to survive on marginal terrain (Dwivedi et al.,2011). Various tree species have been identified globally for their biofuel potential, with an emphasis on sustainability and low competition with food crops (Pandey et al., 2012). In India, there is a diverse range of over 100 tree species that produce seed oil suitable for biodiesel. These oil tree species can be cultivated on non-agricultural lands, ensuring that they do not compete with food and fodder production. Globally, tree-based biofuels are crucial for energy security. Palm, jatropha, pongamia, and mahua are among the feedstocks investigated by the US, Brazil, and Europe for biodiesel production. Tree-borne oilseeds (TBOs) are critical for biodiesel generation in India, which relies heavily on fossil fuel imports. India has implemented both the National Biofuel Policy (2009) and the National Agroforestry Policy (2014). The former policy aims to replace fossil fuels with biofuels, targeting a 5% replacement by 2012, 10% by 2017, and exceeding 10% beyond 2017. The latter policy focuses on integrated land use options for livelihood, environment, and energy security. Notably, important tree-borne oilseeds (TBOs) such as Jatropha, Karanj, Mahua, and Simarouba have been efficiently incorporated into agroforestry systems, yielding beneficial results and providing a significant source of non-edible oilseeds from trees. The need for alternatives to fossil fuels is particularly urgent for countries like India, which have a vibrant economy and high consumption of fossil fuels, heavily relying on imports. Biofuels, as renewable liquid fuels derived from biological sources, have proven to be promising substitutes for oil in the energy sector (Mahapatra et al.,2021). In India, the focus on biofuels is primarily on non-edible oils obtained from tree species’ seeds since oils from food crops like corn, sweet sorghum, and soybean cannot be diverted for biodiesel production (Raju et al., 2012). Tree-borne oilseeds (TBOs) are cultivated across the country in various agro-climatic conditions, including forest and non-forest areas, as well as wastelands, deserts, and hilly regions. India has a vast potential for oilseeds derived from trees, such as Mahua (Madhuca indica), Neem (Azadirachta indica),

Tree-borne vegetables spring out from woody perennial plants. There are too many trees in nature across the globe which offer edible fruits, a few of them are exploited for vegetable purpose. Of course, in popular parlance, vegetable gives the connotation of the product of herbaceous crop, but there are vegetables which are the product of woody perennials. In the present agri-horti-scenario, where diversity in product range is the most sought after aspect, attempts are underway to popularize culture of such vegetables which have not yet found commercial momentum at the grower’s field. Tree-borne vegetables are one such group which needs proper popularization to really help to percolate their farming. These vegetables being vested with woody nature, tap root system, bark covering and stress tolerance mechanism are worth exploitation under diverse farming systems prevalent across the country. Further many tree-borne vegetables are rich in nutrients also and as such add to their plus identity.

Agroforestry systems are not simply systems where trees and crops or animals give useful products to the farmers, rather systems where trees and crops and/or animals interact. Interaction literally means influence or mutual or reciprocal action. So component interaction refers to the influence of one component of a system on the performance of other component as well as the system as a whole.

In agroforestry systems, trees are grown in close proximity to crops and pasture. Their performance would largely depend on their ability to share various growth resources in a given environmental situation. Various interactions take place between the woody trees and herbaceous plants (crops or pastures) which is referred to as tree-crop interface. These interactions take place through the media of soil and microclimate and may exert favourable or adverse effects on the crop. Study of interaction helps to know how the components of agroforestry utilize and share the resources of the environment, and how the growth and development of any of the components will influence the others. Interaction occurs both above and below the ground and includes a complex set of interactions relating to radiation exchange, the water balance, nutrient budget and cycling, shelter and other microclimatic modifications.

The success of an agroforestry system relies heavily on exploitation of the component interactions. In an ideal relationship, production of trees as well as crops or grasses in combination could be comparable to their sole performance. Agroforestry could be even more advantageous if the production of associated components is increased due to influence of trees. This is possible because trees are capable of improving productivity of soil in many ways. A large number of trees are known to fix nitrogen symbiotically. Nevertheless, instances of crop inhibition in association of trees are not uncommon. Such inhibitions are primarily caused by shade effect as well as competition for belowground resources such as nutrients and water. In some cases inhibitory effect may also result from allelochemicals secreted by some of the tree species.

Bonsai first appeared in China over a thousand years ago on a very basic scale, known as pun-sai, where it was the practice of growing single specimen trees in pots. These early specimens displayed sparse foliage and rugged gnarled trunks which often looked like animals, dragons and birds.

With Japan’s adoption of many cultural trademarks of China, bonsai was also introduced to Japan during the Kamakura period (1185-1333) by means of Zen Buddhism, which at that time was rapidly spreading around Asia. Once bonsai was introduced into Japan, the art was refined to an extent not yet approached in China. Over time, bonsai, which was confined to the Buddhist monks and their monasteries, were introduced as a symbol of prestige and honour. It became an important part of Japanese life by being displayed on specially designed shelves.  For the Japanese, bonsai represents a fusion of strong ancient beliefs with the Eastern philosophies of the harmony between man, the soul and nature.

Renewable energy sources, are the sources of power that quickly replenish and which can be used again and again. For this reason they are sometimes called energy resources. The main sources of renewable energy and their advantages and disadvantages are :

Solar
Energy from sunlight is captured in solar panels and converted into electricity.  Potentially it is an infinite source of energy supply, but the solar panels are costly.

Vedic literature indicates that the energy in the universe gets transmitted into the human body through star galaxies. The star galaxies of our universe are divided into 27 parts each signified by a particular star (nakshatra). Every human being is assigned to a particular star by virtue of his birth time.  Each star is associated with a tree. The tree associated with his star gives the universal energy to the human being. Thus astrology gives us a chance to identify the tree which is auspicious to us, being associated with our birth star. When one plants the tree associated with his birth star near his dwelling, it will bring good luck and prosperity to him.

The early inhabitants of our country were very conscious of the placement of their dwellings in beautiful surroundings. The best examples are from the West Coast, where the houses were traditionally constructed in the midst of gardens. The Arab traveller and historian, Ibn Batuta, in his itinerary in coastal Malabar recorded their picturesque beauty, as early as in the 10th century AD. The whole compound was planted with trees, which were useful and aesthetic in appeal. The scholarly elite used trees and shrubs mentioned in Kalidasa’s work in their planting schemes. Through the tree and foliage, a path is formed to the main village.

Trees are amazing nature’s creations that are not only important for mankind but also sustain ecological balance in nature. They are the source of livelihood and provide valuable raw material for manufacture of household utility products. They are important from spiritual aspect and have been exhaustively described in ancient Indian texts with their significant Ayurvedic and other potential health benefits. Botanically a “tree.” is a large, long-lived (perennial) woody plant that attains a height of at least 6 m (20 ft) at maturity. A tree possess certain characteristic features such as a trunk (single main self-supporting stem) which gives off spreading branches, twigs and foliage to make a crown. Since the diameter at breast height (dbh) of trees is determined internationally at 1.35 m (4.5 ft) above the ground, a tree must be un-branched at least up to 1.5 m (5 ft) from the ground.

Urbanization coupled with industrial development creates problems of environment like air pollution, water pollution, noise pollution and civic ugliness. Of late, there is a greater awareness of environmental issues and increasing understanding of several attributes of vegetation. This led to an intensification of activity in the field of landscape horticulture to combat pollution and create an aesthetic environment for recreation and healthy living. Planning and execution of landscape projects for different urban locations should be done to meet both aesthetic and ecological requirements.

Trenching and diversion structures are engineering methods employed to control water flow, especially in agricultural fields and construction sites. Trenching involves the creation of narrow and deep excavations, primarily used for laying utilities, drainage systems, or other underground infrastructure. These trenches, often deeper than they are wide, require careful design and adherence to safety protocols to prevent cave-ins and ensure worker safety.
Diversion structures, such as ditches, channels, or small dams, are designed to redirect the flow of water away from vulnerable areas. They help manage surface runoff, reduce erosion, and provide controlled irrigation. In construction settings, these systems protect worksites and foundations from water damage, while in agriculture, they optimize water usage and prevent soil degradation. Together, these techniques play a vital role in water management and land preservation.
PURPOSE AND UTILITY OF TRENCHES
Trenching serves a wide range of purposes in civil engineering and construction projects. It is commonly used for installing essential underground infrastructure such as water pipes, electrical cables, sewage systems, and telephone lines. In residential settings, trenching is frequently employed for tasks like laying irrigation systems, connecting plumbing lines, installing electrical cables, and placing pipes for heating systems.
At the municipal or city level, trenching plays a critical role in establishing and maintaining public utility networks. It enables the installation of extensive drainage systems, sewer pipelines, and city-wide electrical and communication lines. Proper trenching ensures the safe and efficient placement of these utilities while minimizing surface disruption and ensuring long-term functionality

Introduction

Time Series Analysis (TSA)

TSA is a crucial tool in the study of climate change, as it allows researchers to carefully examine patterns and changes in weather parameters over time. By analyzing time series data for temperature, precipitation, and other weather variables, scientists can identify trends and develop models that accurately describe the underlying structure of the series. These models can then be used to make predictions about future changes in weather patterns and the potential impacts of climate change on the environment and human society. The accurate forecasting of climate change using TSA can inform policy decisions and facilitate adaptation strategies to mitigate the effects of a changing climate.

Components of Time Series

When analyzing a time series, we often want to separate the different components that contribute to its overall behavior. The classical decomposition method is a widely used technique that breaks down a time series into four components: trend, seasonal, cyclical, and irregular.

Abstract

Climate variability/change is one of the very significant concerns discussed in the recent two decades. Its impact on air temperature and precipitation has received massive attention worldwide as they affect both the spatial and temporal patterns of water availability. Hence, it is becoming clearer that analysis of trends in air temperature and rainfall is significant in studying the impacts of climate variability/change for water resources planning and management. Therefore, the aim of the study was to detect theannual, seasonal and monthly trends in air temperature and rainfall in the Râmgangâ river basin. Daily air temperature (Bareilly and Moradabad) and rainfall data (Shahajahanpur, Bareilly, Bareilly BPO and Moradabad)of 40 years (1971 to 2010) were used for the study. Non-parametric Mann-Kendall test and theTheil-Sen’s Slope Estimator was used for determination of estimating the trend and magnitude of the trend. Findings revealed that the basin is experiencing a warming trend because of the rise in themaximum and minimum air temperature. In case of rainfall, Moradabad showna significant high positive trend during the monsoon season. This would alter the river run-off in long run if the existing trend continues to persist like this.

Abstract
India’s agriculture sector plays a critical role in economic development, offering employment to a significant rural population and contributing notably to GDP. Despite limited natural resources, India is among the world’s top producers of various crops and livestock. However, post-harvest losses, infrastructure gaps, and limited value addition hamper its full export potential. In recent years, agricultural exports have surge, with rice, spices, sugar, buffalo meat, and marine products emerging as key contributor. India has also expanded its export footprints across major global markets, including the USA, China, Bangladesh, and the UAE. Recognizing the strategic importance of agri-exports for economic growth, employment generation, and rural development, the government has launched initiatives such as the Agriculture Export Policy (AEP), Agri Export Zones (AEZs), and Market Access Initiatives (MAI). These measures aim to boost market access, infrastructure, and competitiveness. The integration of e-NAM, focus on quality standards, branding through Geographical Indications (GI), and establishment of Agri-Cells in key countries further support India’s goal of becoming a global agriexport powerhouse. This work underscores the importance of a coherent export strategy to enhance farmer income, promote sustainable practices, and position India as a key player in the global agricultural value chain.

Introduction

Production system under arid and semi-arid region faces several biophysical constraints (high solar radiation, low and erratic rainfall, high wind velocity, poor soil conditions, etc.). Availability of irrigation water and irrigation potential in these regions are meager. Nutrition, food security and sufficient livelihood options based on agriculture are the major challenges of the people living in these regions. Sustainable productivity in these regions cannot be achieved by monoculture of either seasonal or forage crops, and thus hinges the need for diversifying the cropping pattern through fruit based cropping system which has good potential particularly in the arid and semi-arid regions. Because hunger and malnutrition are often linked to poverty, providing economic opportunities through horticultural production not only helps family incomes, but also addresses food security and nutrition. Thus, cropping system approach for agricultural production has greater significance in these regions.

Introduction
India possesses wide range of climatic and physio-geographical conditions, which are favourable for the production of various kinds of horticultural crops such as fruits, vegetables, flowers, nuts, spices, plantation crops (coco nut, cashew nut and cocoa) etc. The production of fruits and vegetables (F&Vs) in India is 81.2 million tonnes and 162.2 million tonnes from an area of 6.9 million hectares and 9.2 million hectares respectively during 2012-13 (NHB, 2013).  India is the second largest producer of F&Vs in the world after China. India’s share in the world production of F&Vs is 11.84 per cent and 13.36 per cent respectively (Lagzi, 2013). The importance of horticultural sector can be gauged from the fact that the contribution of horticulture sector in agricultural gross domestic product (agri-GDP) stands at around 30 per cent (Economic Survey, 2013-14).

Abstract
India’s grape industry has emerged as a key contributor to horticultural exports, driven by increasing production, evolving market strategies, and trade liberalization. This chapter analyses the trends, growth, instability, and export potential of both fresh (HS 080610) and dried grapes (HS 080620) from India between 2004 and 2023. While, India ranks among the top global producers, the fresh grape segment has seen consistent growth in exports, supported by initiatives like APEDA’s GrapeNet traceability system and private-sector innovation through companies like Sahyadri Farms and Mahindra Agri. In contrast, the dried grape segment, despite high growth potential, has faced volatility and continues to show a trade deficit. Using compound growth rates (CGR) and the Cuddy-Della Valle Index (CDVI), the study evaluates performance across production, trade value, and instability metrics. Exports potential maps highlight untapped markets such as the United States, EU, and Southeast Asia. Strengthening post-harvest infrastructure, ensuring compliance with international quality standard, and investing in value addition remain critical for India to enhance its global competitiveness in grape exports.

India’s livestock sector is one of the largest in the world and dairy farming is the single largest contributor to country’s GDP, apart from being the biggest source of employment. India has 56.7 per cent of world’s buffaloes. Buffalo genetic resource greatly helps the countries to assess their strengths and potential to harness the nature’s gift and India is fortunate in terms of having largest buffalo population, huge buffalo germplasm diversity (13 recognized plus 14 distinct population groups) and the world renowned buffalo breeds: Murrah, Banni, Jaffrabadi and Nili-Ravi.

Introduction Consumer demands for convenience and mildly processed meals with long shelf lives have led to unique and current developments in food packaging solutions (Dobrucka and Cierpiszewski, 2014). Additionally, the development of unique and creative packaging solutions that do not compromise food safety or quality is being fueled by the current retail trend and changing lifestyles (Dainelli et al., 2008). The widespread use of packaged meals has raised consumer demand for prepared foods like microwaveable dinners, and the growing popularity of smaller food packages all help to fuel the food industry's explosive growth in creative packaging (Restuccia et al., 2010). The rise in food-borne microbial outbreaks, which calls for the usage of packaging that possesses antimicrobial qualities while retaining food quality, is another major driver of new food packaging (Appendini and Hotchtkiss, 2002). The initial advancements in packaging were electrically powered packing equipment, flexible packaging, metallic cans, aseptic packaging, aluminium foils, and flexographic printing. A considerable movement away from metal, paperboard, and glass packaging in favour of plastic and flexible packaging was also brought about by the discovery of various materials such as polyester, polypropylene, and ethylene vinyl alcohol polymers.

Introduction

The food processing industry is a sunrise sector and contributes around 14% of Gross Domestic Product, 13% of India’s exports and 6% of total industrial investment. The Indian food retail market is expected to reach Rs 61 lakh crore by 2020 and the food processing industry accounts for 32% of the country’s total food market. This is considered as one of the largest industries in India and is ranked fifth in terms of production, consumption, export and expected growth.

The drift towards urbanisation and busier way of life, pave path to tremendous bounce in the food market. Nowadays consumer’s approach to being fit is not about going to gym, but also consulting dietitians and adopting an adjusted eating routine. Consumer’s behaviour concerning food consumption has undergone significant changes as a result of the increased awareness about different value added food products, brands, and cuisines, and also their greater willingness to experiment and ability to pay. It leads to the concept of food security in to nutritional security. Companies are offering a wider range of products to the consumers as a result of their investments into product innovation, research and development. At present, various value added products with versatile colour, shape, ingredients etc are available in worldwide market. Among this, some food items like processed fruits and vegetables and dairy products have witnessed a momentous growth in export also. Recent surveys indicated that for companies manufacturing processed foods and beverages, rise in the obesity rate is a great challenge. Hence, efforts were made to develop commercially viable, new process protocols to design healthy products from underutilised food commodities.

Food Safety

The term “safe food” has different standards to different consumers rather than just being the food handled and prepared through proper cleaning, washing and cooking. Safe food means food prepared on clean and sanitized surfaces with equipment, utensils and dishes that also are cleaned and sanitized. Nowadays consumers are extra conscious about the safety and quality of food and for that reason food safety issues have changed, so have society’s methods for making food as safe as possible. Accordingly, “food safety” means assurance that food is acceptable for human consumption according to its intended use (FSSAI 2017).

Abstract

In afforestation and reforestation programs, seed has become a valuable commodity and its collection, identification, handling, processing, testing, storage and certification requires prudent planning. The research and development in seed science and technology have made significant progress in recent years. The quality of seed has been the subject of increasing interest among Forest Managers and the Scientists. Not every seed is suitable for sowing. Sometimes, the seeds do not develop into normal plants or the plants produced do not produce the expected harvest. This manuscript reviews, the progress made to-date in the forest tree seed germination and highlights future line of action.

Introduction

The term geographic information systems (GIS) has come to mean, variously, an industry, a product, a technology, and a science. As such, the term invokes different perceptions dependent on whether the viewpoint is that of the software developer, the system marketer, the data provider, the application specialist, or the academic researcher, among others. A newcomer to the field is likely to be bewildered by the multiple uses of the same term, or, seen alternatively, different definitions of the same term. For instance some find it distasteful to use of the conventional acronym GIS and prefer Geospatial Technology. With all the variety of perceptions predicting the future of GIS is a cumbersome business. The most certain inference we can gain from the available trends is, it is growing and is poised for further growth. Geotechnology along with Nanotechnology and Biotechnology is considered as of the three most promising growth industries for the near future.

Introduction

The protected cultivation aims to create a favorable environment for harnessing maximum potential even in adverse climatic conditions. Farmers in India are facing different challenges including small and fragmented land holdings, climate change, vagaries of weather, poor soil health and lack of knowledge and exposure to modern agricultural technologies. The protected cultivation farming is emerging as one of the better alternatives in agriculture and gaining foothold in India. However, for successful protected cultivation farming, one needs to understand the protected cultivation structures, climate control, production technologies, plant protection, water management, marketing, guidelines and policies. At present, various innovations are adopted under the greenhouse technology viz., Soil based cultivation and soil less cultivation. Soil less cultivation consist of solid media based and liquid media based. Solid media include coco-peat, vermiculite, perlite, rice husk, sawdust, mass grass, wheat - paddy straw, sand, gravels, rock wool etc. whereas liquid based media include hydroponic, aeroponic and aquaponics cultivation.

1. Introduction

Intermediate moisture foods are semi moist foods that have some of their water bound by glycerol, sorbitol, salt or certain organic acids, thus preventing the growth of many microorganisms (Stewart et al. 2001). It is now well recognized that fruits and vegetables are dehydrated to an intermediate moisture level (20-50%) (Stewart et al. 2001; Purvi et al. 2003). As the intermediate moisture products are characterized by a semi moist consistency so these foods have enough moisture content to permit easy chewing but low enough water content to prevent spoilage production of intermediate moisture foods is based on an increased scientific understanding of the chemical reactions involved in traditional food preservation methods (Purvi et al. 2003).
There will be better retention of original flavor and texture compared to fully dried products, with concomitant reduction in bulk, weight and cost of packaging, transportation and storage. Such intermediate moisture foods are more appropriate for developing countries in view of their minimal processing requirements, stability under ambient conditions, safety, convenience, ease of nutrient content adjustment, energy savings and low capital investment. They are also eminently more suited than dehydrated or canned foods for military rations (FAO, 2005).

Introduction

Mithun (Bos frontalis), or ‘Gayal’ or ‘Eso’ or ‘Sial’ or ‘Sandong’ or ‘Wei’, is a rare bovine species, exclusively found in the northeastern hill region (NEHR) of India at an altitude of 300-3000 m. It plays an important role in the socio-economic and cultural life of indigenous tribes of Arunachal Pradesh, Nagaland, Mizoram and Manipur and is aptly referred to as the ‘Pride of Northeast India’ (Mukherjee et al. 2019). Besides India, mithun population is distributed to China, Bangladesh, Thailand, Bhutan, Myanmar, and Malaysia. The Indian mithun is a medium- to large-sized majestic ruminant with a characteristic jet-black body, an ash-colored forehead, and ‘white stockings’ on all the limbs. This unique animal has a special preference for salt feeding, is a skilled browser even in steep, hilly terrain, and does not need pasture land like cattle. Mithun is primarily reared under a free range system as an important source of lean meat, rich in amino acids, proteins, PUFA, etc. On September 1, 2023, the Food Safety and Standards Authority of India (FSSAI) officially certified the mithun as a food animal (Joshi et al., 2021; Lalchamliani et al., 2024; Ramesh et al., 2024). Compared to milk from other species, mithun milk has much larger quantities of fat, lactose, solids-not fat (SNF), calcium, important vitamins A, D, and E, essential amino acids, and polyunsaturated fatty acids (Devi et al., 2023).

“Knowledge Management is the process by which an organization identifies, creates, manages and delivers information to enhance workforce performance. The purpose of knowledge management is to provide information collected from employees, best practices, clients, competitors and other sources in a format that employees can use to the productivity and quality of their work”

Before attempting to address the question of knowledge management, it’s probably appropriate to develop some perspective regarding this stuff called knowledge. Consider this observation made by Neil Fleming [1996] as a basis for thought relating to the following points.

The present study was undertaken to study the trends of area, production and productivity of major fruit crops in the Himachal Pradesh state. The study was based on secondary data from 1974-75 to 2010-11. The data was collected from several government publications and website. To analyze the trend of area, production and productivity of major fruit crops in the Himachal Pradesh state, the linear, quadratic and exponential functional forms were used. To fit the trend, quadratic functional form was used due to its higher R² value as compared to other two forms. Besides these, compound growth rate, coefficient of variation and instability index was also estimated. The effects of area, productivity and their interaction towards increasing production were also estimated in the present study. The growing of major fruit crops was not risky in the Himachal Pradesh state as revealed by the lower coefficient of variation. The coefficients of variation (CV) of area, production and productivity of major fruit crops were less than 100.13 per cent. The instability indices for area, production and productivity for major fruit crops in the Himachal Pradesh state were positive and thereby indicating less risk for growing major fruit crops in the state. The increase in production is due to increase in area as well as interaction of area and productivity of fruit crops in the state. This may be due to the adoption of high yield variety seed of major fruit crops and adoption of improved methods by the farming community during last decade.

Abstract

Ethnobotany is the area of study which include direct interaction of human and plants. This communication compiles and evaluates 301 ethnobotanically important medicinal plants used by ethnic tribes for the treatment of different ailments living in Uttarakhand Himalaya. The state is a home of five major tribes, viz., Bhoxa, Bhotiya, Tharu, Raji, and Jaunsari. These tribal people have age-old relations with plants, and their indigenous knowledge passed from one generation to another. In this communication, a total of 90 plant families were reviewed and recorded that Asteraceae, Lamiaceae, Rosaceae, Fabaceae, Amaranthaceae Apiaceae, Combretaceae, Euphorbiaceae, Anacardiaceae and Malvaceae members are frequently used as medicinal plants. Total 68 roots of different species, followed by leaves of 55 species, whole plants of 29 species, fruits of 26 species and 28 types of seeds of different plants families used by locals for the treatment of various diseases such as fever, cold, cough, diabetes, skin problems, digestive problems and other associated ailments. The mode of application of herbal formulations varies from tribe to tribe. Herbaceous communities belonging to 160 species were the frequently used plant groups followed by trees, shrubs, and lianas. The decoction was recorded as the most frequently used method of preparation. Medicinal plants sold in the market was not primary for local people rather herbal plants locally available used as food, spice and beverages preparations. Therefore, there is a need for proper documentation and conservation planting of these unique medicinal plants growing in the Himalayas.

Introduction

The tribal population comprising 705 tribal communities spread over various states of India contributes 8.6 % of total India’s population (Census 2011). Their culture, traditions and practices interpenetrate almost all the aspects of Indian culture and civilisation. From the Aryan, Dravidian to the Indo-Tibetan languages, Indian tribal culture has also seen a tremendous merging of cultures within its own people. Some of these communities share similarities and yet are diverse in their religious and traditional beliefs. Some are prominent worshippers of the Hindu deities while others follow the path of the Christian missionaries. Animism and all forms of pagan worship are still prevalent in these communities. The societies by which these tribal communities survive are very patriarchal in their outlook although some tribal communities have gradually inherited the modern forms of society where each one is respected for his or her own set of views and beliefs. India’s tribal population is over-dependent on agriculture and forest related livelihood sources. 

Since the beginning of the Planning process, efforts have been made to ensure that the tribal people were included in the growth process. However, the strategy changed with each Five-Year Plan as new lessons were learnt from various developmental efforts. The First Five Year Plan emphasized the provision of additional financial resources through a community development approach to address the problems of tribal people rather than evolving a clear-cut tribal development strategy. Towards the end of the Plan (1954), 43 Special Multipurpose Tribal Development Projects (MTDPs) were created. These MTDPs could not fully serve the interest of the tribal people since the schemes were numerous and of a general nature. This approach continued during the second Five Year Plan. In the Third Plan, a different strategy for tribal development was evolved by converting the Community Development Blocks, where the concentration of tribal population was 66% and above, into Tribal Development Blocks (TDBs). By the end of the fourth Five Year Plan, the number of Tribal Development Blocks in the country rose to 504. The strategy of development through Tribal Development Blocks had its limitations as well, as it failed to address the cause of the tribal population of the country living outside the Tribal Development Blocks, which comprised more than 60% of the total tribal population. During the th on 5 Five Year Plan period, the exercise of identification of tribal majority blocks was undertaken. These were later constituted into 194 ITDAs/ITDPs in the country.

The present Tribal Sub Plan (TSP) strategy was initially developed by an Expert Committee set up by the Ministry of Education and Social Welfare in 1972 under the Chairmanship of Prof. S.C. Dube for the rapid socio-economic development of tribal people and was adopted for the first time in the Fifth Five Year Plan. The TSP strategy, with some modifications, continues till this day and the salient features concerning TSP for States, are given below:

INTRODUCTION

Tribulus terrestris L. (Gokhru) is an important industrial herb, belonging to family Zygophyllaceae which includes 285 species representing around two dozen genera. Members of this family are distributed in tropical and warm climates. Most species are shrubs, but some grow as small trees or herbs. T. terrestris is a mat forming plant that grows extensively in warm and dry areas all over the world. In China, India, Greece and other parts of the world, the species finds wide application in folk medicine, in polyherbal formulations and as food supplement for physical rejuvenation, to enhance muscle strength, sexual potency, etc. Amidst many positive claims, clinical trials are recommended to evaluate its reported toxicity in animals.

The Hans Krebs cycle, known by different names like the citric acid or tricarboxylic acid cycle, was named after the scientist Hans Krebs. The citric acid cycle is named after the citrate product formed in the cycle. The name tricarboxylic acid is given as citrate itself, which is a tricarboxylic acid due to the presence of three carboxyl functional groups (-COOH).
The tricarboxylic acid (TCA) cycle occurs in aerobic conditions and within mitochondrial ETC, involving various sequential oxidoreductase reactions. The cycle requires Acetyl-CoA (C2 molecule) and oxaloacetate molecule (C4 molecule) to begin with the formation of a citrate molecule (C6 molecule). Acetyl-CoA is generated from the pyruvate (glycolysis), the fatty acids (lipolysis), or by oxidative deamination of specific amino acids. The complete oxidation of a glucose molecule results in the end products like energy (ATP), CO2 and H2O. A molecule of Acetyl-CoA has two carbons. It is formed from a three-carbon pyruvic acid molecule generated from the glycolysis of a sixcarbon glucose molecule. Acetyl-CoA is the substrate for this cycle and is an energy-rich molecule having a thioester bond between coenzyme A and acetic acid.
8.1 Formation of acetyl-CoA from Pyruvic Acid
Pyruvate is obtained by glycolysis or the oxidation of glucogenic amino acids. The pyruvic acid produced in the cytoplasm crosses the inner membrane of the mitochondrion to enter the mitochondrial matrix, where it undergoes oxidative decarboxylation, forming Acetyl-CoA. Acetyl-CoA carries (carrier molecule) the acetyl group to the citric acid cycle. It also links various metabolic products with the TCA cycle. Such products can be from the EMP cycle, beta-oxidation, and oxidative deamination of amino acids. Oxidative decarboxylation of pyruvic acid needs a complex enzyme system known as pyruvate dehydrogenase
