Ornamental Industry

Floriculture as a multi-billion dollar industry has been undergoing unique revolution in terms of production and marketing of high value ornamentals such as cut flowers, loose flowers, potted and foliage plants there by emerged as fully export oriented activity. Owing to the steady increase in demand of flowers, floriculture has become one of the important commercial businesses in horticulture. Presently, floriculture industry in India has been growing with compound annual growth rate of 25 percent over the past decade (Muthukumaran, 2009). It has been found that commercial floriculture has higher potential per unit area than most of the field crops and therefore, it is a lucrative business. Indian floriculture industry has been shifting from traditional flowers to cut flowers for export purposes.Maharashtra, Karnataka, Andhra Pradesh, Haryana, Tamilnadu, Rajasthan, West Bengal have emerged as major floriculture production areas. The export of floricultural products from India has been on an increase in the past five years due to high demand for floriculture products in importing countries. The estimated total area under floriculture in India is 2,82,000 ha. Tamil Nadu stands first followed by Karnataka and Andhra Pradesh, West Bengal, Maharashtra, Rajasthan, Delhi and Haryana. Approximately 16,57,000 metric tonnes of loose flowers and over 5,20,000 metric tonnes cut flowers are produced in India during 2015-16. Total export of floriculture products is 22,518 MT with value of 479 crores (APEDA, 2015). Major importers of ornamental products from India are USA, Germany, UK, Netherland, and UAE.

Abstract

Pruning is the most important cultural operations in tea cultivation. Time of pruning affects health of bush, incidence of pests and disease, yield and distribution of crop. Root starch reserve at the time of pruning affects the recovery of bush and hence considered as the most crucial factor for deciding time of pruning. Downward movement of photosynthates was found maximum in December and January, thereby maximizing the starch reserve in roots. Maximum recovery of tea bush and minimum loss in annual crop was found when pruned during December – January. Pruning in remaining months (February – November ) may result in crop loss to the tune of 5 per cent – 37 per cent in plain areas. Clonal varieties differ in root starch accumulation during winter months hence pruning time of individual clone needs to be decided accordingly to enhance recovery of plants.

1. Introduction
Crop health valuation plays a vital part in modern agriculture as it positively stimulates food security, economic constancy, and ecological sustainability. This process involves monitoring and evaluating the growth and development of crops, finding possible stressors or diseases, and executing suitable management practices. Judicious and precise evaluation of crop health permits early exposure of diseases, pests, and other irregularities. Detecting these problems at their early growth stages can aid prevent extensive occurrences and decrease the need for unnecessary pesticide use, indorsing justifiable crop management practices. Assessing crop health on a regular basis help in enhancing yields by detecting factors that could inhibit crop productivity. Agricultural systems can be made resource-efficient by incorporating tools, modern technologies and information management systems that come under the precision agriculture concept. Modern scientific improvements, comprising Global Positioning System (GPS), grain yield monitoring system, Variable Rate Technologies (VRT), sensor networks, and Femote Sensing (RS), have assisted farmers to detect in-field heterogeneity of crop and soil and adopt site-specific farm management practices. Varying the application of inputs with VRT can decrease the cost of inputs and labor, increase productivity, and decrease the potential environmental influences from the overuse of farm inputs. However, the success rate of VRT needs precise and consistent information on the location and extent of crop and soil health conditions, such as crop nutrient shortages, soil and crop water deficiency, and injury caused by insect pests, weeds, or pathogens. So far, the dominant remote sensing technologies that the farming sector has used are visible (VIS), Near-Infrared (NIR), and short-wave infrared (SWIR) sensors. The use of thermal sensors in agriculture is to some extent narrow despite its wide use in the areas of medical science (Ring and Ammer, 2012), intelligence/military (Hinz and Stilla, 2006), and the food processing sector (Vadivambal and Jayas, 2011). By providing temperature variations of soil and crop canopy, thermal remote sensing has the prospective to be used for various

Lichens are the most fascinating and widely distributed organisms on earth. The lichens are unique in having two microorganism in a single plant- a phycobiont (alga) and a mycobiont (fungus) forming a thallus that does not resemble either symbionts in the free living (non- lichenized) state. By virtue of the peculiar structure and physiology, lichens have high tolerance of drought and cold and are able to grow in the diverse geographical regions from icy expanses to tropical and subtropical parts and from drier, hot deserts to moist humid climate. Lichens grow on any substratum that provides a convenient foot hold to them. This may be soil (terricolous), humus (humicolous), stones, rocks, brick (saxicolous), lime plaster (calcicolous), leaves (folicolous), tree trunk (corticolous), decaying wood (lignicolous) and other man made substratum like iron pipes, asbestos sheet and glass panes. Sometimes lichens also grow on some insects and animals. Lichens which are bigger in size and shape can be easily recognized as leaf like (foliose) and thread like (fruticose) (commonly called macrolichens), while those which forming a crust over the substratum and quite smaller in size are categorized under microlichens.

Apart from altitudinal variation, the vegetation and forest types of higher plants also play an important role in determining the type of lichen flora of the region. Based on the forest types six lichen vegetation zones are known in India such as: Moist tropical evergreen forest, Cold deserts in the Himalayas, South Peninsular region, Mid Eastern Indian & Peninsular Plateau, Dry and arid regions and Indo-gangetic plains of central India, Coastal regions of India and Andaman & Nicobar Islands. The cold deserts in the Himalayas exhibit some unique group of lichens having restricted distribution only in such habitats.

1. Introduction

The word ‘lichen’ has a Greek origin, which was referred to the superficial growth of fungus like organism on the bark of olive trees. Theophrastus, the Father of Botany coined the term ‘lichen’ during 300 BC and introduced this group of plants to the scientific world.

Lichen is a combination of two organisms, an alga and a fungus, living together in symbiotic association. Sometimes instead of an alga a cyanobacterium (blue-green alga) may be present in the lichen thallus. The algal component in the lichen is generally called as ‘photobiont’ as it contains photosynthetic pigment. The fungal part is called as ‘mycobiont’ (myco = fungus). The photobiont and the mycobiont loose their original identity in symbiotic association and the resulting organism is the lichen which behaves as a single organism, both morphologically and physiologically. Hence, the lichen is called as a composite organism. The lichen thallus is made 90% of mycobiont which provides shape, structure and colour to the lichen. In a lichen thallus whatever visible from outside is fungal part, which holds algae inside its body (Fig. 1) and therefore, the lichens are placed within the Kingdom - Fungi. The fungi present in lichens are called as ‘lichenized fungi’. Among the 20,000 lichen species present in the world, 98.9% of them belongs to Ascomycetes group while Bacidiomycetes and Deuteriomycetes groups are represented by only 0.1% and 1%, respectively.

Introduction

Soil is one of the crucial natural resources that support life on the earth and controls the economic conditions of the nation. Soil erosion has become a serious problem in both rainfed and irrigated areas of India thus it of vital importance to raise awareness about soil erosion and their reclamation / management methods, so that future land management decisions can lead to more sustainable and resilient agricultural systems. In India almost 130 million hectares of land, i.e., 45 % of total geographical surface area, is affected by serious soil erosion through gorge and gully, shifting cultivation, cultivated wastelands, sandy areas, deserts, and water logging.

In India, the soil is eroded at an average annual rate of 16.35 tonnes per hectare which means 5334 million tonnes per year for the country as a whole. Out of this, about 29 per cent is permanently lost to the sea, while 61% is simply transferred from one place to another, and the remaining 10% is deposited in reservoirs (which mean the storage capacity is reduced by 1-2 per cent annually (Narayana and Ram Babu, 1983)). Singh et al. (1990) estimated that the average annual soil loss is about 15.2 tonnes per hectare and at national level it amounts to about 4978 million tonnes annually. The annual erosion rates vary from region to region. In dense forests covers, snow-clad cold deserts and arid regions of western Rajasthan, the annual erosion rates are less than 5 tonnes per hectare. On the other hand, about 64 per cent of the total soil is contributed by highly to very severely eroded areas, such as the Shiwalik hills (annual rate is more than 80 tonnes per hectare), the Western Ghats, black and red soil regions, ravines and other gully eroded areas and the northeastern region. For the first time, Gurmel Singh prepared map of soil erosion in India (Fig. 7.1), on the basis of iso-erosion lines i.e. line joining the place of same erosion rates.

Submerged soils/Flooded soil

Submerged soils are the type of soils that are saturated with water for a sufficiently long time in a year. This gives the soil the following distinctive gley horizons resulting from oxidation-reduction processes:

The soil is intermittently saturated with water, oxidation of organic matter is slow and it accumulated within the “A” horizon. Fe and Mn are deposited as rusty mottles or streaks if the diffusion of O2 into the soil is slow in the second horizon, whereas if the diffusion is rapid, they are deposited as concretions.

Types of submerged soils

1. Waterlogged soils- Waterlogged soils are saturated with water for a sufficiently long time annually to give the soil the distinctive gley horizons resulting from oxidation-reduction processes. Saturation with water may be due to impermeability of the soil material, or the presence of an impervious layer, or a high water table.

2. Marsh Soils- These types of soils are more or less permanently saturated or submerged. Freshwater marshes can be classified according to their origin into upland, lowland, and transitional. Upland marshes are poor in bases and have pH 3.5-4.5 because they receive mainly rainwater. Lowland marshes are saturated or submerged with water-carrying bases and have pH 5.0-6.0.

Food Business Regulatory System in India

In India Food Businesses are regulated by only One authority i.e. Food Safety and Standards Authority of India (FSSAI). This comes under the control of Ministry of Health and Family Welfare of the Govt. of India.

FSSAI – Food Safety and Standards Authority of India

The FSSAI or Food Safety and Standards Authority of India was incorporated under the Food Safety and Standards Act (FSSA) of 2006. It consolidated various acts & orders that were previously applicable and used to handle food related issues in different Ministries and Departments. The basic objective of formulating FSSAI has been to lay down science-based standards for items of food and to regulate their manufacture, storage, sale, distribution, and import to ensure the availability of adulteration-free and wholesome food for human consumption.

Abstract

Tea [Camellia sinensis (L.) O. Kuntze], of family Theaceae, is an important cash crop  worldwide. It is an evergreen shrub cultivated in humid and sub-humid tropical, sub-tropical, and temperate regions of the world, and grows mainly on acidic soils. Due to limitation of expansion of tea cultivation in new land, import of low cost high quality tea, increasing vertical productivity is the best option of Indian tea Industry. The primary need of the tea industry today is to develop high yielding clones with better quality and stress tolerance potential. Conventional tea research has contributed appreciably to the genetic improvement of tea over the past several decades, but it is time-consuming and labor intensive.

1. Introduction
Functional feed additives are specialized, non-nutritive substances added to animal feed with the primary aim of enhancing health, growth, and performance beyond the basic nutritional requirements. Unlike traditional feed ingredients that primarily provide essential nutrients, functional additives are intended to optimize physiological functions and overall well-being in animals. In the context of aquaculture, these additives are particularly crucial for improving the efficacy of fish diets, as they can significantly influence various health and performance parameters.
Functional feed additives can be derived from a diverse array of sources, including:
• Microorganisms: Probiotics and prebiotics that support gut health and improve digestion.
• Plants: Phytochemicals, such as flavonoids and alkaloids, which have antioxidant, anti-inflammatory, and immunostimulatory properties.
• Natural Compounds: Various extracts and essential oils known for their therapeutic effects on fish health.
By integrating these additives into aquafeeds, aquaculture practitioners aim to promote fish welfare, enhance production efficiency, and ultimately contribute to sustainable fish farming practices.

The group of animals constantly used in laboratories for general research in all discipline of science is called as laboratory animals. Commonly, it includes rats, mice, rabbits and guinea pigs. However, under certain circumstances, additional animal species like hamsters, non-human primates, amphibians, fowl, sheep and pigs can also be included. This term incorporates traditional laboratory animals, farm animals, wildlife and aquatic animals. Nontraditional animals, inclusive of invertebrate species are also included where they are relevant to the unit’s mission. Generally, these animals come under vertebrate but broadly laboratory animals may be classified in two major groups i.e. laboratory mammals and non-mammalian laboratory animals. The laboratory mammals include mouse, rat, guinea pig, rabbit, cat, dog, ferret, gerbil, bats, hamster, mink and monkey (Rhesus). Beside these mammalians the large domestic animals/livestock are also used as laboratory animals (horse, cow, sheep, goat etc) for fulfilling the demands of various laboratories. Poultry is also used as non-mammalian laboratory animals and Specific Pathogen Free (SPF) chicks are at utmost demand for production and testing of biologicals. The other non-mammalian laboratory animals includes reptiles (tortoise, lizzards and snakes), insects (cockroach, drosophila, house fly, house cricket, locusts, tsetse fly, stablefly etc) pisces (fishes and snails) and amphibians (toad and frog). Laboratory animals have been used extensively for basic research in drug and bacteria screening, toxicology, antibiotic sensitivity testing, animal models of diseases and production/testing of biologicals. Laboratory mammals are also valuable for diagnosis of infectious diseases in man and domestic animals. In this chapter the most commonly used laboratory animals i.e. mice, rats, guinea pigs and rabbits will be discussed.

Introduction 
Heterocyclic chemistry is advancing rapidly, driven by its diverse applications and crucial role in drug discovery (Kabir & Uzzaman, 2022; Vala et al., 2022). Among various heterocycles, nitrogen and oxygen-containing compounds such as pyrazoles, thiazoles, and triazoles are especially notable for their potent biological activities (Li Petri et al., 2020). These compounds play a key role in addressing diseases caused by microbes, resistant strains, and genetic mutations. Advances in synthetic methods have enabled the development of vast heterocyclic libraries essential for drug screening. Remarkably, heterocyclic frameworks account for nearly 75% of modern low molecular-weight drugs, highlighting their significance in medicinal chemistry (“Thematic Issue ‘Heterocyclic Compounds in Medicinal Chemistry, 2020). Within this context, 1,2,3-triazole has gained significant attention due to its exceptional stability under oxidative, reductive, and hydrolytic conditions, as well as its efficient and regioselective synthesis (Vaishnani et al., 2024). Its unique structural features such as lipophilicity, polarity, rigidity, and favorable pharmacological properties along with strong binding affinity to biomolecular targets, make it an indispensable scaffold in bioactive heterocycles (Devasia et al., 2022). Moreover, 1,2,3-triazole has been used as a bioisostere in medicinal chemistry, aiding the development of pharmaceutical drugs. 1,2,3-Triazoles display a wide array of therapeutic activities, including antiepileptic (Pålhagen et al., 2001), anti-platelet (Campos et al., 2009), anti-microbial (Baddam et al., 2024; El Malah et al., 2020; Mendapara et al., 2024), anti-viral (Farghaly et al., 2024; Gadali et al., 2024; Sabt et al., 2024), anti-inflammatory (Ambala et al., 2024; Awasthi et al., 2024; Qi et al., 2024), anti-cancer (Belay et al., 2024; Bimoussa et al., 2024; Duan et al., 2024; Meenakshy et al., 2024), anti-leishmanial (Molaei et al., 2024; Rodrigues Gazolla et al., 2024), antiplasmodial (A. Yadav et al., 2024; J. Yadav & Kaushik, 2024), anti-alzheimer (Shareghi-Boroujeni et al., 2024), and anti-HIV (Alvarez et al., 1994; Feng et al., 2021; Lazrek et al., 2001) effects. They also act as enzyme inhibitors (Dhameja et al., 2022; El-Naggar et al., 2024; G. Kumar et al., 2024; A. Singh et al., 2024; M. Singh et al., 2024), and anti-convulsants, and protect against snake venom (Ornellas et al., 2024; Simas Pereira Junior et al., 2024). Notably, approved drugs containing 1,2,3-triazole include tazobactam (ß-lactamase inhibitor), cefatrizine (anti-bacterial), and rufinamide (anti-convulsant) (Figure 1).

Introduction

Adoption of green revolution technologies during 1960s led to increased productivity and elimination of acute foodgrain shortages in India. These technologies primarily involved growing of high-yielding dwarf varieties of rice and wheat, increased use of chemical fertilizers and other agrochemicals, and spread of irrigation facilities. This was also accompanied by other modern methods of cultivation, which included maximum tilling of land, virtually clean cultivation with complete removal of crop residues and other biomass from the field, fixed crop rotations mostly involving cereals, and elimination of fertility- restoring pulses and oilseed crops in the highly productive north-western plain zone of the country.

The rapid growth of Large Language Models has demonstrated that increasing model size, training data and computational resources can significantly improve performance. This chapter examines the theoretical and empirical foundations of scaling laws and their relationship with optimization strategies used to train and deploy increasingly capable LLMs. It discusses the major scaling dimensions of model parameters, dataset size and computational budget and explains how predictable relationships between these factors influence model development. The chapter considers the foundational work on scaling laws and the subsequent movement toward compute-optimal training approaches. It also examines distributed training, advanced optimization algorithms, memory optimization, data curation, quantization, pruning and efficient inference. Particular attention is given to Mixture-of-Experts architectures, efficient attention mechanisms and inference-aware scaling. The interaction between scaling laws and optimization is presented as a synergistic process in which scaling principles guide resource allocation while optimization techniques improve computational efficiency. The chapter concludes by discussing emerging capabilities, sustainability, hardware requirements and responsible scaling of future foundation models.

INTRODUCTION

The cultivated almond (Prunus dulcis (Miller). D.A. Webb; Syn. Prunus amygdalus L. Batsch.) known as “Badam” in hindi is an important stone fruit tree species producing highly nourishing nuts of great medicinal value, called as almond. Badam Pappu (Telugu), Badam Paruppu (Tamil), Baadami (Kannada), Badam kayu (Malayalam) are other local names for almond in India. Surprisingly, the almond is not a true nut member, but rather is actually a family member of stone fruits such as nectarines, peaches, plums and cherries. For this reason, some people refer to an almond as a fruit. It is a medium sized deciduous tree belonging to Rosaceae family which produces edible seeds in hard outer shell and is cultivated mainly between latitudes 36o and 45o N. The almond is the most favoured nut with Indians and is very much relished by people. Spain , USA, Itlay, China, Iran, Greece, Tunisia, Turkey, Pakistan, Afghanistan, Algeria, Morroco, France, Persia and Syria are the important almond growing countries. In India it is mainly cultivated in the Kashmir valley and some parts of Himachal Pradesh.

13.1. Introduction

Any written, printed, or graphic matter that is present on the label and serves the purpose of promoting the sale of any product is known as food label (WHO). It is believed in general that food packaging and proper labelling plays an important role in food safety as it gives information regarding allergens present, manufacturing site, expiry date, nutritional information etc.

Consumption of unhealthy diet leads to many non-communicable diseases. Therefore, it is the responsibilities of food manufacturers and regulating bodies such as FSSAI and BIS to work hand in hand to provide safe and healthy food to the consumers. Labelling is an important tool useful to disseminate nutritional information to the consumers. Labelling promotes healthy eating among consumers and gives them an option at the time of purchase to choose healthy food. Information in labelling the enables consumers to choose appropriate food according to their diets and lifestyle (Grunert and Wills, 2007). In addition, the information related to nutritional content of the food must be present in such a way that it well understood by every consumer (Wills et al., 2009).
