Nitrogen is the most important plant nutrient for increasing crop productivity. A few prokaryotic microorganisms are able to fix N2 directly mediated by enzyme nitrogenase. Annual biological nitrogen fixation (Table 96) is estimated to be around 175 million metric tonnes per year of which about 139 million tonnes (79%) are accounted for by terrestrial fixation (Burns and Hardy 1975).

The nitrogen fixers involved are metabolically diverse but the process is similar and depends upon (1) nitrogenase (Nase) enzyme complex (ii) a high energy requirement (ATP) (iii) anaerobic conditions for nitrogenase activity (iv) source of strong reductant.

The symbiotic process is known to be one of the important contributors to the nitrogen cycle both from agricultural and ecological points of view. The soil bacteria of the genus Rhizobium colonizes and forms nodules on the root of leguminous plants such as clover, lucerne (alfalfa), pea, chickpea, pigeonpea, beans, groundnut, Vigna species etc.

The nitrogen uptake in legumes by some unknown process was demonstrated through agronomic experiments by J.B. Boussigault in 1838 which was opposed by Liebig and others. However, Hellriegel and Wilfarth’s experiments (1886-88) clearly showed that the growth of non-leguminous plants, barley, oats etc. was directly proportional to the amount of nitrate supplied while in case of leguminous no such relationship existed and growth of the leguminous plants picked up in some cases after the seedling stage. Beijerinck (1888) isolated the bacterium from the root nodules in pure culture which lead to study their morphological characteristics and physiology.

Frankia is potent nitrogenous biofertilizer for forest trees since it establishes symbiotic association with non-leguminous plants. Nitrogen fixing non leguminous trees thrive in temperate condition. The species belong to Casuarinaceae are an exception and grow successfully in tropical areas. Alnus for temperate regions and the genus Casuarina for tropical and sub-tropical regions stand out examples of the benefits they provide to ecosystem by the way of nitrogen fixation. They have an excellent potential to adapt themselves to grow under diverse geographical and environmental conditions providing enough fuel, fodder, pulp and timber. The microsymbiont within these root nodules of non-leguminous plants has been identified and designated as Frankia (Becking, 1970).

Historical Developments

First of all Boussingault, a French farmer during 1838 drew attention that non-legumes were capable of fixing atmospheric nitrogen. The roots of Alnus were described as warty brownish biomass as large as man’s fist (Woronin, 1866). Frank and coworkers (1887a, b, 1891) studied the nodulated nitrogen f ixing trees regardless of whether they were leguminous or non-leguminous (actinorhizal). Frank believed that the bacteroids were protein deposits but subsequently he named the causative organism as Frankia subtilis. Moller (1885, 1890) reported the causative organism in the nodules as plasmodia and Frank also revised his opinion and pointed out that the causative organism was a fungus. Such conflicting results were due to imperfect techniques to differentiate between vesicles and sporangia. Later the organism was renamed as Frankia bruchorstii to honour Frank and his coworker, Brunchorst (Moller, 1890).

Azolla, a fresh water fem is a rich source of nitrogen especially for low land rice farming. It is found in rice paddies in many tropical countries like China, India, Korea, Philippines and Vietnam. The agronomic importance of Azolla lies in its ability to fix atmospheric nitrogen through the symbiotic association with a blue-green alga, Anabaena azolae. The symbiotic association can fix nitrogen proportional to its biomass produced. When Azolla is grown in paddy f ields and subsequently incorporated as green manure, the nitrogen contained within Azolla biomass is mineralized during the process of decomposition.

Azolla is a genus of small aquatic fern comprising 7 living and 25 fossil species, which is globally distributed. It occurs on still water ponds, lakes, swamps, lagoons and paddy fields in both tropical and temperate regions. Because of its rapid growth, high nitrogen percent and its ability to grow in stagnated waters, it has been used as organic manure in Vietnam and China for centuries. Its use in India and other countries is relatively recent. Azollla pinnata is native to India and widely distributed.

There are several bacteria which fix atmospheric nitrogen and do not have a symbiotic partner such as a plant. There are conclusive evidences regarding nitrogen gains due to free living bacteria (Dart and Day, 1975) The diazotrophic bacteria have been classified based on the mode of nutrition and oxygen requirement (Alexander, 1977, Knowles, 1977). Free living nitrogen fixing bacteria fix nitrogen in soil and their population in rhizosphere of plants are significantly higher than in non-rhizosphere soils

Although the economic and ecological significance of many of these bacteria have yet to be established, the most promising diazotrophs are Azotobacter, Azospirillum, Beijerinckia and Clostridium. Azotobacter and Beijerinckia are some of the most preponderant, non-symbiotic nitrogen fixing bacteria. Studies on these organisms in Indian soils have been done earlier by Rangaswamy and Sadasivam (1964) Sen and Barooah (1964) and Jagtap and Bhide (1971). Among the free living bacteria, Azotobacter is the most intensively investigated. Several species viz., A. chroococcum, A. vinelandii, A. macrocytogenes, A. agilis and A. insignis were reported but A. chroococcum is the most common specie encountered in arable soils.

The accumulation of nitrogen under non-leguminous and cereal cropping systems seem to be generally universal at least in the tropics. Free-living heterotrophic nitrogen fixing bacteria are very widely distributed taxonomically, geographically and ecologically. But only a few genera and species are known to possess the potential for high amount of nitrogen fixation. Azospirillum has shown high nitrogen fixation attributes. The association of Spirillum lipoperum (Azospirillum brasilense) and Digitaria decumbens was reported by Dobereiner and Day (1974).

I. Spirillum

The description of members of genus Spirillum was available as early as 1670s by Leeuwenhoek (Dobell 1960 and Muller 1773). But the genus Spirillurn was created in 1832 by distinguishing it from phototrophic spirilla which were placed in a separate genus Thiospirillum (Ehrenberg, 1838). The subsequent developments of the taxonomy of the chemo- heterotrophic spirilla which generated knowledge of their characteristics, were extensively reviewed by Giesberger (1936) and Williams (1959 a, b).

Rice is grown in about 40 million hectares of land in India and nitrogen requirement for the crop is 60 lakh tonnes based on the present levels of consumption. Rice production has to be sustained and increased to provide staple diet to our increasing population. Blue green algae is a potentional biofertilizer in rice because of their capacity to meet both carbon and nitrogen requirement naturally from the air. They are microscopic algae which are collectively called phytoplankton produce basic organic matter forming the first link in food chain and alongwith replenish the oxygen content of atmosphere. Algae contain proteins, Vitamins, iodine, bromine and substances of antibiotic and stimulatory nature. The soil algae are divided into chlorophyta (green algae) cynophyta (blue green) bacillariophyta (diatoms) and xanthophyta (yellow-greens).

De (1939) suggested that fertility of rice fields is maintained due to the growth of blue-green algae. Different types of blue-green algae have been reported to colonize the rice fields. The cells such as heterocysts in Anabaena, Nostoc, Tolypothrix etc. which have capacity to fix atmospheric nitrogen under aerobic condition and unicellular and non- hetercoystous forms also fix atmospheric nitrogen under microaerophilic conditions.

Phosphorus is one of the essential plant nutrients, which is required in optimum amounts for proper growth of plants and soil biota. Being a constituent of ATP it is involved in various processes such as cell division, energy generation and transfer of genetic characteristics and regulation of metabolic pathways (Theodorou and Plaxton, 1993). Phosphorus constitutes about 0.2% plant dry weight (Schachtman et al., 1998). The average soil contains 0.05% phosphorus but only one tenth of this is available to plants due to its poor solubility and chemical fixation in soil (Narayansamy et al., 1981, Barber, 1984). About 98 percent of Indian soils have inadequate supply of available phosphorus (Ghosh and Hasan 1979, Hasan, 1994). A survey of Indian soils showed that out of 363 districts, only 2,2% were high, 51.5% medium and 46.3% were low in phosphorus content (Ghosh 1982).

The problem of P fertilization may become serious in coming years because of the fact that manufacture of phosphatic fertilizers requires the use of non renewable resources such as high grade rock phosphate and sulphur which are becoming costlier. The situation is further aggravated by the fact that P is readily fixed in the soil and the average utilization efficiency of added fertilizer P by plants ranges from 15-25% only (Gaur 1982, 1990). The recent report showed that 42 per cent of soil samples fell in low category, 38 per cent in medium and 20 per cent in high category (Motsara, 2002). It has been observed that the vast alluvial tracts of the country are either low or medium in available P. Hence they need P application at recommended rates.

The term ‘mycorrhizae’ was coined more than a century ago (Frank 1885) describing that the roots of most plants are colonized by fungi and transformed into fungus roots organ. Mycorrhizae result from a mutualistic symbiosis between plant roots and certain fungi. Roots of most flowering plants live in mutual symbiosis with mycorrhizae which bio-tropically colonise the root cortex and extra-metricial mycelia help the plant to obtain plant nutrients from soil (Barea, 1991).

These fungi are ubiquitous in soil and are found in the roots of many Angiosperms, Gymnosperms, Pteridophytes and Thallophytes (Mosse et al., 1981). The mycorrhizal fungi perform the function of root hairs. The fungus takes carbohydrates from the plant and in turn supplies the plants with nutrients, hormones and protects it from root pathogens. The dependency of fungal species on host plant ranges from obligate to facultative (Brundrett, 2002; Read and Perez-Moreno, 2003). The mycorrhizal plants have greater tolerance to toxic heavy metal, nigh soil temperature, soil salinity, unfavourable soil pH and to transplantation shocks.

They play an important role in increasing plant growth and nutrients uptake (Bagyaraj, 1992, VasanthaKrishna and Bagyaraj 1993). These fungi can be used to promote biotechnologically developed plant in soil (Varma and Schuepp 1994).

Introduction

Conventional agriculture is highly dependent on fossil fuel based mineral fertilizers to compensate for removal of plant nutrients by crops. Chemical fertilizers are not only in short supply but also are very costly. The preparation and use of organic manures are not being practiced in a scientific manner to harness the plant nutrients removed by plants, animals and humans.

The application of chemical fertilizers to soil alone and in an imbalanced way has resulted in deterioration of soil health and its quality. The use of chemical fertilizers has to be reduced to check the soil and water pollution and simultaneously the role of soil microorganisms has to be augmented by different ways such as greater use of biofertilizers. Moreover, the demand for organic food particularly both in developed and developing countries is on rise which opens up immense possibility to use organic manure and biofertilizers for production of foods grains, fruits, vegetables, spices, tea and coffee. Therefore, the production and the use of biofertilizers assumes greater significance and could be an excellent biological alternative to chemical fertilizers.

Introduction

The successful combination of technology and finance, commonly referred to as Financial Technology (henceforth, FinTech), can be understood as “technology enabled financial innovation” that may result in new business applications, models, products and/or processes, that create manifold material impact on f inancial markets and provision of financial services (Schueffel, 2016).

FinTech presents a promising prospective of bettering the situation of financial inclusion in developing countries like India by leveraging on technology in an innovative manner. Inclusive growth can be achieved through FinTech by means of broad-based prosperity, reduction in transaction costs and better access to financial services to the underserved (Sahay et al., 2020). In this context, Fintech companies are institutions applying technological innovations to increase efficiency and create enhanced access to the finance industry. There has been tremendous growth of such companies in recent years and it has also captured the interest of investors alike.

Introduction

In the annals of history, the term “Renaissance” evokes images of a time marked by profound cultural, artistic, and scientific rebirth. The Renaissance of the 14th to the 17th century was characterized by an extraordinary surge in creativity and intellectual achievement, which laid the groundwork for the modern world. Today, we find ourselves at the cusp of a new Renaissance—a Digital Renaissance—propelled by the rapid and relentless advancements in technology. This new era, like its historical counterpart, is marked by a transformative shift that is redefining every aspect of human life, from how we work and communicate to how we learn and govern.

This chapter delves into the essence of this transformative era, exploring the fundamental technological innovations reshaping our world and their far-reaching impacts on society. We will examine the pivotal technologies driving the Digital Renaissance, including artificial intelligence, blockchain, the Internet of Things (IoT), and other emerging technologies such as virtual and augmented reality and 5G networks. By understanding these technologies and their applications, we can appreciate how they collectively contribute to a digital transformation that is as revolutionary as the artistic and scientific achievements of the past.

The digital age has revolutionized the way we live, work, and interact with the world around us. Digital transformation has become a crucial imperative for businesses of all sizes and industries, enabling them to not only adapt to the changing landscape but also thrive in it. (De Lucas,2021). The rapid advancement of technologies such as 5G, cloud computing, big data, artificial intelligence, IoT, and blockchain has opened up a plethora of opportunities for enterprises to enhance their operations, improve customer experiences, and gain a competitive edge. (Anjali et al, 2023). Businesses can increase their reach, automate jobs, obtain insights from data, personalize services, and streamline procedures by utilizing these technologies. They must reconsider their business models and implement more flexible and agile strategies in response to these exponential changes. (Bansal et al, 2020, Fenech et al, 2019).

Introduction

Given the interdependence of all ecosystem units and humans, education for supportable sustainable development (ESD) is a crucial educational tool. The Brundtland Report of 1987 also highlights a crucial element when it states that “everyone must have access to the basic necessities of life and the opportunity to realize their dreams of a better life for sustainable development.” In order to alter the prevailing beliefs and attitudes which people have about themselves, society, and the environment, ESD — which is mapped out on the three pillars of the economy, society, and environment—plays a crucial role. The core tenets of ESD are those that support sustainability, including social tolerance, gender equity, intergenerational equity, poverty reduction, and environmental preservation and renovation.

The Rio Declaration, which outlines 27 sustainability principles, makes this claim. As they support the development which is related to education and reorient current education to promote sustainability, these principles can assist governments, society, and educational institutions in routinely classifying information, principles, skills, and values. Globally, education which is related to sustainable development, or ESD, is widely regarded for its substantial contribution to improving livelihoods and advancing society’s transition to sustainability. Although opinions on the viability of sustainable development vary, it is generally agreed that moving toward a sustainable future requires increasing public awareness, education, and training. Notwithstanding the difficulties in defining sustainability, it is evident that many social behaviours— such as those involving pollution, inefficient energy use, water conservation, and other issues—are not sustainable.

Introduction

A vision of the industrial landscape of the future that emphasises safeguarding society and the environment has lately surfaced as the “Industry 5.0” idea. People collaborating with robotics and intelligent machines are referred to as “Industry 5.0.” By utilising cutting-edge technologies like big data, Internet of Things (IoT) and robots can help people operate more efficiently and quickly. The Industry 4.0 pillars of efficiency and automation are given a more human touch through this. It aims to combine the inventiveness and problem solving abilities of human employees with the powers of mechanisation and artificial intelligence, ultimately producing a more productive and adaptable production environment. This paradigm shift emphasises the value of human decision-making and intervention in the industrial context while addressing the drawbacks of complete automation. By fusing the strengths of both robots and humans, Industry 5.0, which is still in its early stages, has the potential to revolutionise several industries. In 1987, the United Nations Commission defined sustainability as addressing the requirements of the present without compromising the capacity of people in the future to address their issues. Sustainability is essential in Industry 5.0, the next stage of industrial development characterised by growing digitization and automation. Within this paradigm, sustainable practices reduce resource consumption, trash, and emission levels, leading to more effective utilisation of resources like materials and energy. Industry 5.0’s commitment to sustainability reduces waste, carbon dioxide emissions, and environmental impacts. Utilising green technologies and eco-friendly practices helps reduce environmental impact

Financial inclusion, which is the process of accessing and properly utilizing formal financial services, is an important factor in powering economic development and poverty reduction. Study undertakes a broad cross- country analysis of financial inclusion and its impact on social and economic factors. Applying data from respectable bodies like World Bank, International Monetary Fund, Eurostat and United Nations Development Programme, the study applies regression analysis and fixed effects models to determine how income, employment, income inequality, urbanization and human development affect financial inclusion. The outcomes show the complicated interplay between these actors and financial inclusion over various national situations.Financial inclusion is becoming a key component of equitable economic development and poverty alleviation worldwide. The importance of financial inclusion is undisputed, but its causes must be identified. This research article uses a comprehensive cross- country analysis to explain how various civilizations utilize financial services. The study will examine the relationship between financial inclusion and its key socio-economic factors— income levels, employment dynamics, income inequality, urbanization trends, and human development—to inform inclusive economic development policymakers, researchers, and practitioners. The data demonstrates that financial inclusion promotes economic development by helping people save, invest, and manage risk. Additionally, academics have focused on socio-economic issues including income distribution, urban-rural divide, and education level in shaping financial inclusion patterns within and within nations. These characteristics’ effects on financial literacy are yet unknown, thus more empirical study is needed to develop evidence-based policy.

Introduction

Indian economy is basically an agrarian economy. In spite of all challenges and difficulties faced over the years, the sector still serves as the lifeblood of the nation, by standing as the major source of livelihood for over half of the population by guaranteeing food security for its teeming millions. A significant contribution to the GDP of the nation is still ensured by the agriculture sector. The development of a nation highly centres on its primary agriculture sector and Indian economy have a much diverse dependence on the agriculture sector in terms of its growth and development. The nation straightaway necessitates a tremendous shift entirely to sustainable agricultural practices in its development trajectory.

Despite its undeniable significance and praised role, Indian agriculture currently faces multifaceted challenges, which significantly restrict the production and productivity level of the sector as a whole and the farmers in particular. Its high time that the Indian agriculture sector, which stands as the backbone of the nation needs to go through a looming transformation. The industry 4.0 revolution is a vibrant platform for the sector to make a complete transformation. The traditional face of the sector will transform towards a modern makeover by taking up technological advancement and digitalisation. The wider transformative opportunities will ensure a return of the Indian agriculture sector to the forefront in the nations growth and development.

Introduction

No revolution occurs without disruption. Its effects break down traditions, behavior, relationships, ways of thinking, and methods of education. (Barreiro, 2021) throughout history, from the hunter-gatherer era to the present day humanity has experienced multiple industrial revolutions impacting both social and economic domains. The latest industrial revolution, which has ushered in digital transformation and enhanced productivity at reduced costs, introduces a new lifestyle distinct from our traditional daily routines. It also aims to foster a more sustainable overall environment. (Javaid et al., 2022).

The rise of Industry 4.0 is fueled by both rapid technological advancements and various social and economic factors. Central technologies propelling Industry 4.0 include wearable, augmented reality, simulation, autonomous vehicles and robots, additive manufacturing, distributed ledger systems like block chain, big data analytic, mobile computing, and cloud computing. These technologies influence and facilitate the development of new and innovative business models. (Industry 4.0 Implications for Higher Education Institutions 2019)

The advent of Industry 4.0, characterized by the integration of advanced technologies has revolutionized various sectors, including higher education. As these technologies reshape industries, they also redefine educational paradigms, creating a more interconnected, efficient, and personalized learning environment. This transformation, known as Education 4.0, responds to the demands of the Fourth Industrial Revolution by preparing students with the skills and knowledge necessary to thrive in an increasingly digital and automated world.

Introduction

Financial inclusion has become a global agenda because it is now well recoganised that a nation can prosper only if it ensures inclusive growth. Financial access and use of formal financial system, the means of financial inclusion, have positive association with inclusive growth (Levine and Demirguc-Kunt, 2008). The financial systems which are more inclusive have provided broader access to appropriate financial services to ensure that the benefit can be availed by poor and disadvantaged sections of the society (Akter, 2016). Since, financial inclusion is the process of ensuring availability of f inancial services and well-timed and sufficient credit as required by vulnerable groups such as low income segment and weaker segment of the society at an affordable cost (Rangarajan Committee on financial inclusion, 2005). Thus, the study of financial inclusion on the basis of socio economic factors is the key to investigate individual characteristics associated with financial inclusion (Allen, Kunt, Klapper, Peria, 2012). Understanding financial usage on the basis of socio economic factors enables framing appropriate financial inclusion strategies to achieve financial inclusion in real sense. Many international agencies like International Monetary Fund, Asian Development Bank, World Bank release data on financial inclusion around the world. Global findex report is published by World Bank after the interval of every three years to present the picture of financial inclusion on various socio economic parameters. Around the world, 74% adults, 72% female, 70% income poorest population, 63% out of labour force population and 66% rural population report to have account at formal financial system (World Bank Global findex report, 2021).

Introduction

Work-dwelling or workplace well-being describes all aspects of the working lifespan of workers from the point of view of quality, safety and physical environment. It pronounces the workers’ feelings about their work, their working environment, the climate at work and work organization. According to WHO (2010), a healthy workplace environment not only merely finds the absence of illness but also a state of comprehensive physical, mental and social comfort. Work and health hence have a reciprocal relationship that concerns occupational health wellbeing and confers decent work environments i.e. (i) payment of reasonable income; (ii) safety-security in employment and working environment; (iii) guarantee of equal opportunities and treatment for all; (iv) enclosure of social protection for the workers and their families; (v) offering prospects for personal development and inspiring social integration and (vi) allowance of workers to express their apprehensions and to organize (ILO, 1999). In the entrepreneurial sphere, globalization along with fast industrial progress is supposed to be accountable for occupational health hazards and related workplace ill-being, work insecurity, the lack of protection for workers’ health and well-being in the form of work-related accidents, illness and stress, lack of workers’ compensation and paid sick leave, lack of maternity protection, excessive hours of work, etc.(https://www.ilo.org/). This was evidenced in the recent report of ILO (2023) where it was found that 2.3 million people around the world surrender to work-related accidents or diseases every year which links to over 6000 deaths every solitary day (www.ilo.org). Subsequently, there are about 340 million occupational accidents where 160 million are fatalities of work-related illnesses annually in the World.

Introduction

Agriculture has always been linked with prosperity, man power and the ability to feed and raise human population. In earlier times, humans as man power were deployed on the fields to do all the necessary operations to cultivate the crops, but during the industrial revolution, with development of different farm machines the uses of human labor on the fields were drastically decreased. Further, with advancement of technologies and more availability of computers, Artificial Technology (AI) has been gaining momentum in recent years.

AI has the potential to transform the agricultural sector through cost reduction and increased crop yields, and minimizing environmental impacts. AI can help farmers better manage their land, improve crop quality, and increase their productivity In addition, AI can be used to monitor and analyze the health of crops, livestocks, and soils to identify issues and assist in their resolution. The primary idea of using artificial intelligence in agriculture is due its adaptability, superiority, and cost-viability. The customary techniques that were utilized by the farmers were not adequate enough to satisfy their necessities. (Khan et al. 2022) With the right implementation and technology, AI can be an invaluable tool to help farmers increase their efficiency and profitability. In today’s rapidly evolving world, where the demand for food continues to escalate amidst concerns over environmental sustainability and resource scarcity, Artificial intelligence (AI) has become a transformative force in agriculture, from optimizing crop production and resource management to enhancing decision-making processes. Globally, AI is changing how we approach farming techniques.

Concept: Operations conducted before and after harvest are essential components of the system for producing high-quality seeds. If enough care is not taken in the initial stage, there most likely won’t be any resources left to get high-quality seed. Like this, carefully produced, high-quality seed may lose a significant percentage of its worth if post-harvest management protocols are not adhered to. Its quality is highly correlated with soundness, fullness, and homogeneity of physical characteristics (size, shape, density, colour, and appendages), in addition to mechanical planting’s simplicity and improved crop establishment. Improving the seed that has been gathered and getting it ready for secure storage till needed are accomplished through the effective and efficient process of seed processing. To increase the quality of the seed lot, the goal of seed processing must be to optimize the physical properties of the seed and the constituents of the harvested seed mass. The three main steps in seed processing are conditioning, grading, and applying protectants or enriching with nutrients. These steps are completed in compliance with established protocols and standards (McDonald and Copeland 1997; Agrawal 1996; Jorgensen and Stevens, 2004). The distinct qualities of the crops and the surroundings are taken into consideration while adjusting the machines and operations.

Concept: The preservation of viable seeds from the moment of collecting until they are needed for sowing is known as storage. Every year, a significant quantity of seeds loses their usefulness due to incorrect storage. Seeds need to be preserved and stored dry. As was previously mentioned, seed moisture content and storage temperature have the biggest effects on how long seeds last. The three main environmental elements that impact seed deterioration and loss of viability are moisture, temperature, and oxygen percentage. For over 90% of species, reducing seed moisture content (MC) to certain thresholds consistently lengthens the seed’s lifespan (Roberts 1973). These species are categorized as “orthodox” in terms of the conditions in which they should store seeds; under suitable dry, cool conditions, they typically maintain viability and germinability even after extended periods of storage. Ellis and Roberts’ improved viability equations have addressed the quantitative impacts of both drying and cooling for orthodox seeds. The life of the seed is often doubled for every 1% drop in seed moisture (when seed MC fluctuates between 5 and 14%) and every 5 oC drop in storage temperature (between 0 oC and 50 oC) (Harrington 1972). Low seed MC and low temperature are hence fundamentals of traditional seed storage. Careful regulation of these two factors is necessary to achieve optimal storage life. But most seed produced annually just has to be kept from harvest until the following planting season. Depending on the type of seed, it may or may not need to be stored at temperatures and relative humidity above room temperature. Regardless of any modifications made for unique uses, the local climate storage facility needs to have a few essential components (Barre, 1954; Wheeler and Hill, 1957).

Objectives of Seed Grading

Minimization of heterogeneity to the lowest level and enhancement of the homogeneity to the highest level in the seed lots received by the processing unit.

Principle

Separation of seed lots based on differences in the physical properties of the seeds.

Post harvest activities include threshing/ seed extraction, drying, pre-cleaning and conditioning, cleaning, fine-cleaning or grading, seed treatment, weighing and bagging/ packaging, sealing and labelling, storing, and transportation for marketing. Except for transportation and marketing, all these activities collectively known as seed processing. However, for most of the crop, threshing or seed extraction, basic cleaning even drying is done in the farm itself and in the processing unit, the threshed seed is received.

The objective of the seed processing is to prepare the harvested seed in such a way that seed of highest purity and quality would be available for marketing, also for planting. The cleaning and the grading are the foremost activity of the seed processing. The seed, which is received in the processing unit, contains many undesirable particles, which as such cannot be used for marketing, hence cleaning and grading become necessary.

Objective of Seed Storage

The primary goal of seed programs, which include storage, is to maintain the high standards of the seed from harvest until the crop is sown in the following or future seasons. Additionally, seeds are kept in storage for longer periods of time for a variety of reasons, including protection against crop failures during emergencies or natural disasters, maintaining active genetic stocks for breeding, germplasm preservation for long-term use, stock preservation for the domestic and international seed trade in response to market demands, and parental line seed preservation for the transnational seed industry during one or more growing seasons. The seeds of most major agricultural species can be classified as either orthodox or desiccation tolerant. A drop in storage temperature and relative humidity, commonly referred to as seed moisture content, shortens their shelf life. Seeds deteriorate even in dry storage because of alterations caused by pests and pathogens as well as physiological deterioration. This is accurate, even though the amount of time seeds takes to germinate and stay viable varies according to the makeup of the different plant species. A good seed program handles the seed with care, regulates the store’s temperature and relative humidity (or seed moisture in the case of hermetically sealed containers), and adheres to good sanitation practices to preserve the high planting value of the seed in terms of purity, germination, vigour, and seed health.

Concept: It’s a natural process that modifies the cytology, physiology, biochemistry, and physical characteristics of seeds. These modifications lower viability and ultimately result in the seed’s death. A decline in the proportion of germination indicates degradation, and weak seedlings are produced by seeds that do germinate. The factors that impact the ability of seed to be stored include the seed’s quality at the time of storage, its pre-storage history (environmental factors during pre- and post-harvest stages), its moisture content or ambient relative humidity, the temperature of the storage environment, the amount of time the seed is stored, and biotic agents. Seed will inevitably get damaged when being stored (Balesevic-Tubic et al., 2005). The quality of the seed at the time of storage, its pre-storage history (environmental factors during pre and post-harvest stages), its moisture content or ambient relative humidity, the temperature of the storage environment, the length of time the seed is stored, and biotic agents are factors that affect the seed’s ability to be stored. Different physical changes can happen to seed during storage because of factors like temperature, moisture content, and length of storage. The viability and vigor of the seeds may be impacted by these modifications.

Concept: Reduction of seed moisture content to the acceptable levels for enhancement of storability and longevity is known as seed drying.

The moisture content of seed is negatively related to its storability. As the moisture content of seed increases, its storability decreases. Adequate drying of seed prolongs viability for reasonably long periods without cold storage. The process of drying begins with physiological maturity till storage/packaging of seeds to avoid deterioration. The seed is hygroscopic in nature therefore it adjusts its moisture content in equilibrium to the existing environment.

Seed Drying

Seed drying is the process in which an environment with low humidity is created to remove moisture from the seed up to the desired level without any damage to its viability and physical appearance. This seed is stored at low moisture content under the low relative humidity to enhance its longevity. The initiation of seed moisture content and the desired level are what dictate the amount of the drying process, and these elements are determined by the following

• Type of seed: This will consider the longevity behaviour, seed content, and seed structure (i.e., how well the species stores energy).

Concept of Delinting

Cotton seed clumps because of linters getting trapped on them after ginning. Gin-run seeds have very low flowability and do not singulate, making cleaning, upgrading, and precise metering in planting operations challenging or impossible. To singulate the seed and increase flowability, a variety of techniques have been and are employed. Most of the techniques entail removing the tags and linters entirely or partially, although other coating techniques have also been attempted with mixed results, both financially and technically (Mezynski, 1966; Webber and Boykin, 1907).

Methods of Delinting

1. Mechanical Delinting

Mechanical delinting is the usual technique used to improve the flowability of cotton seed. As previously indicated, mechanical delinting basically involves resharpening with finer, closer-spaced saws to remove part of the commercially valuable linters.

During processing seeds are cleaned, dried, and graded which are then treated with specific fungicide and insecticide. Seed at this stage is at best quality, which are then packaged into various packaging materials in a specific weight. Packaging or bagging of processed and treated seed is a requisite for easy handling of the bulk seed. Seed packaging can be defined as filling with seed, weighing and sealing the container whereas seed package as storage container where the seeds are kept for marketing or shipping or till the next sowing time.

The Packaging of Seed Involves

1. Filling bags/ containers of uniform size with seeds of known weight.

2. Providing leaflets inside the package with information about any specific cultural practices needed.

3. Attaching labels or certification tags having information regarding all the quality parameters.

4. Temper-proof sealing of the bag.

5. Storage or transportation of the bags.

Objective

Vegetable seed separation requires specialized training. A little carelessness during the seed extraction process can seriously harm the plant’s viability and vigor in addition to its outward look. Inadequate extraction methods can also result in in-situ germination. The seed can be separated by the following methods.

1. Manual Method

(a) Maceration e.g., watermelon,

(b) Crushing e.g., brinjal,

(c) Scraping e.g., cucumber

(d) Separated e.g., muskmelon,

(e) Scooping e.g., pumpkins and

(f) Extraction e.g., squashes.

Concept: Seed blending is the process of merging two or more types of the same species, for as Kentucky bluegrass cultivars Merion, Baron, and Park. Contrarily, seed mixing refers to the blending of two or more species, however every species may have more than one variation represented, such as Jamestown and Cascade chewing fescue combined with Merion and Fylking Kentucky bluegrass. Seed is typically distributed in blends, primarily Kentucky bluegrass blends, for sod growing purposes. For home lawns, parks, and other utility areas where upkeep levels would not be adequate to maintain pure Kentucky bluegrass turf, mixes of different grasses are typically employed. Naturally, when it comes to pure seed quality, no blend of grass seeds is superior to the individual ingredients. Every time a new blend needs to be made; extreme caution must be taken to ensure that the mixing equipment can be completely cleaned to prevent any contamination from unwanted species—bent grasses are perhaps the most challenging to deal with.

Pre-Treatment Before Sowing

The natural conditions necessary for seeds to germinate are increased by pre sowing seed treatment. Many plants and trees’ seeds require a specific amount of time to mature in their immature portions and to overcome dormancy, which is the absence of certain elements that impede germination, so that the seeds can sprout. Depending on the type of seed, different environmental factors promote different levels of germination. For example, some seeds need to be kept in a very damp, cold environment, while others need to be kept in a dry, hot environment. Different techniques are employed to support seed survival and speed up germination, depending on the size of the lot, the species, the local conditions, and the availability of pertinent tools and facilities. Many species’ seeds don’t germinate successfully unless they are exposed to specific circumstances. Dormancy is the state in which seeds do not germinate unless certain circumstances are met. Conditions in the natural world could include being near fire or being eaten by animals.

Concept: A few of the numerous environmental elements that affect seed quality maintenance are moisture, temperature, humidity, and storage conditions. When some seedborne diseases or pests like insects are taken into consideration, seed quality can still be negatively impacted. Applying one or more pesticides to seed is the most economical and efficient way to keep pests away and improve seed quality.

Because pesticides are harmful, handling treated seeds after application requires additional caution and safety measures.

Definition of Treated Seed

The definition of “treated” is “application of a pesticide or subject seed to a process intended to reduce, control, or repel insects, disease organisms, or other pests which attack the seed or seedlings.”

Stored grain pests are one of the major constraints in obtaining quality seeds. They cause substantial yield loss in storage conditions affecting both the quality and quantity of the produce. Apart from causing direct loss to the grains, they also make them unfit for consumption through their excreta, scales and wings resulting in development of unpleasant odour (Upadhyay and Ahmad, 2011). They also act as a source of medium for growth of fungi or bacteria (Daglish et al., 2018). The method of infestation of stored gain pests is different from the insect pests infesting crops under field condition. Generally, the infestation of storage pests starts after harvesting. It has been reported that in India, there is a loss of about 14 million tons worth Rs. 7000 crores due to the infestation by different storage pests (Chaubey, 2022). The post-harvest loss in terms of quantity and quality by different storage insect-pests accounts for about 10-30 per cent (Rajasri and Kavitha, 2015; Yaseen et al., 2019).

Sanitation

Sanitation and maintaining good hygiene conditions are the important aspect of seed storage in storage godowns. Maintenance of good hygiene conditions will maintain the quality of produce in the long run (Mahapatra et al., 2014) and these practices should not be overlooked. The threshing floors should be cleaned properly before the operation so that there is no mixing of seeds or any insect-pests or pathogens. Harvesting and threshing should be followed by cleanliness of godowns to protect the seeds from the harmful pest and pathogens (Upadhyay and Ahmad, 2011). The storage godowns should be well lighted and the area should be preferably sunny, free from weeds and mostly situated at elevated areas. Damp areas should not be selected for building storage godowns as it will affect the moisture per cent of seeds thereby enabling easy growth of insect-pests and diseases (Parimala et al., 2013). Before bringing the new produce to the storage godowns, they should be cleaned properly. The cracks and crevices of storage godowns if any should be sealed ahead and the walls of the godowns should be whitewashed (Hazam and Kumar, 2022). The new seed lots should not be mixed with the older lots. The floors should be disinfected, and it should be cleaned regularly.

Introduction

The recognition of environment as the desired precondition for human existence and development both by Millennium Development Goals (MDG) as well as Sustainable Developmental Goals (SDG) unquestionably shows its importance and necessity. The impact of climate change is fast getting into our understanding and are realizing the enormity of the situation. Consequently, global environmental issues are a growing concern among the people and communities of various regions today. The impending ecological disasters have forced the right-thinking people and organizations to seek an alternative in the form of managing natural resources without jeopardizing the developmental activities. The challenge is to enhance the standard of living compatible with ecology and environment. This underlines rather unquestionably the need to pursue a line of lifestyle and development design that is compatible with nature and the issue of the environment cannot left to languish at the bottom of priorities.

Introduction

Western world started paying attention to climate change after the Industrial Revolution when collateral environmental problems began appearing with the development. But in India, many shastras gave philosophy of sustainable development before the evolution of many civilizations.

It means that “All this is for habitation by the Lord, whatsoever is individual universe of movement in the universal motion. Man should use all resources by renunciation, he should not see them with feeling of lust”. Here, renunciation means controlled use of resources. It is known as Green Application of the resources nowadays.

Whenever the term ‘green’ is used as an adjective with certain phrases, the said phrase is considered to depict a friendly character with the environment. In this sense, the Cambridge Dictionary defines the word ‘green’ as “relating to or believing in the protection of the natural environment.” For instance, Green Technology, one of those concepts towards which this paper is concerned, will refer to those technologies which are environment friendly. But this won’t help us understand what green technology actually means.

Introduction

In today’s world, where environmental issues are prominent and there’s a growing realization of our planet’s limited resources, the concepts of sustainable harvesting and conservation have become extremely important. They act as guiding principles, directing us to use resources responsibly and to protect the diverse life and ecosystems on Earth. The paper is designed to explore the core principles of sustainable harvesting and conservation, emphasizing their critical importance and the pressing need for a careful equilibrium between utilizing resources and safeguarding the environment. The paper analyzes laws, policies, and delving into Sikkim’s sustainable conservation and harvesting methods, and argues that successful implementation of these strategies presents Sikkim as a model that can be replicated worldwide. Sikkim’s proactive initiatives, such as banning plastic and harmful substances, as well as implementing measures to reduce pollution, showcase a forward thinking approach to environmental stewardship(Sikkim, ND),. These actions set an example for other areas to emulate, promoting a more sustainable and responsible relationship with our natural surroundings.

Introduction

One of the main challenges in sustainable farming is determining the patentability of living organisms, including genetically modified crops and biotech innovations. Balancing the rights of inventors and the public’s access to agricultural resources can be so complex the Seed saving and farmer’s rights Seed saving is a traditional practice where farmers save and reuse seeds from their harvest. However, some intellectual property rights (IPR) regimes restrict farmers’ ability to save and exchange seeds, potentially limiting their autonomy and leading to dependence on commercial seed suppliers. Biopiracy and traditional knowledge Protecting traditional knowledge and preventing biopiracy is a significant concern in sustainable farming. Nearby agriculturists and inborn individuals habitually have imperative conventional information approximately plant sorts and rural procedures that’s esteemed, and they are decently compensated for their endeavors. Maintainable advancement became a major worldwide agenda thing within the afterward decades of the 20th century! According to the Brundtland report from 1987: “Our Common Future,” provided the most recognized concept of sustainable development, meeting future demands without sacrificing existing practices to be adopted for future aspects. (Ahmed Abdel-Latif, 2021). While a few Intellectual property rights have been pointed out such as the plant breeder’s rights trademark, security of plant assortments and ranchers’ rights (PPV and FR), topographical signs, and exchange insider facts are exceptionally significant to horticulture. In expansion, format plans for chips particularly planned for farming; logical papers, and tv programs covering thoughts related to horticulture and partnered segments must be considered. (Datta, 2016).

Introduction

Resource management balances human needs with environmental preservation, focusing on sustainable development, responsible use, and conservation of natural resources. It involves environmental stewardship, economic efficiency, and social equity, ensuring equitable access for all societal segments while meeting present and future demands (Study Smarter, N.D; Mohd Akhter Ali et al., 2023).

There are specific areas such as water, soil, forests, waste, and sustainable harvesting practices. Each area presents unique challenges and opportunities, requiring tailored strategies and interventions to promote sustainability. The interplay between human activities, environmental impacts, and socio economic dynamics through the lens of resource management highlights the need for sustainable practices that balance development with ecological preservation, ensuring equitable resource distribution and long-term economic stability. Emphasis is placed on holistic approaches, participatory decision making, and capacity building to enhance resource governance and promote sustainable practices.

People visit tourist destinations for the purpose of enjoying the beauty, to relax and rejuvenate. One of the popular destinations chosen by all are hill stations. Darjeeling, also known as the Queen of Hills, is a popular tourist destination visited by six-hundred-thousand Indians and thirty-thousand foreigners annually (Bhattacharya, n.d.). The primary attractions that make Darjeeling worth visiting are the magnificent views of the Kanchenjunga range and the lush tea gardens. As a result of the advancement in technology, the luxury of travel is now feasible to all sections of society because of which tourism in India has rapidly expanded in the past three decades. This is the result of: great progress and advancement of the Indian economy, India’s roaring IT sector and promotion of “Unbelievable India” by the Tourism Ministry. Although tourism has significantly boosted revenue and employment, it comes with its downsides: the harm that it poses to the environment if it goes unchecked. Since the number of tourists is greater than the ability of the environment to cope up with, it puts tremendous pressure upon the environment which can have irreversible negative impacts

Introduction

For upliftment of the Indian economy agriculture plays an important role as it has contributed immensely. Nearly, three quarters of India’s family depend on rural incomes. Majority of India’s poor live in rural areas. Most people depend upon the crops, vegetables, fruits grown by these rural population. India’s food security is depended upon the inputs made by the farmers which has been a reason for increasing food insecurity in India. To meet with this accelerated pace a productive, competitive, diversified and sustainable agriculture sector needs to be introduced (The World Bank, 2012).

India being a global agricultural powerhouse, is the world’s largest producer of millet, pulses and spices and also has the largest cattle herd in the world, India also produces largest amount of wheat, rice and cotton. Agriculture is a part of India’s culture and tradition. In India, the culture, tradition and festivals are in a way related to different crops grown by the farmers. Along with this agriculture is deeply rooted with the community lifestyle in India. The community freely share their knowledge related to growing, sowing and harvesting of crops, they also distribute or share the produced crops among each other freely (OECD, 2018).

Introduction

In an era increasingly defined by environmental consciousness and the imperative for sustainable practices, the sports industry emerges as a pivotal arena where innovation in green intellectual property (IP) holds transformative potential. At the forefront of this movement are patents, which not only safeguard inventive ideas but also serve as catalysts for integrating eco-friendly technologies into sports equipment. This chapter explores the profound impact of green patents within the sports sector across four key dimensions, illuminating their role in driving sustainability initiatives and reshaping industry dynamics.

The integration of sustainable technologies in sports equipment represents a paradigm shift towards greener practices. From advanced materials in athletic apparel that reduce environmental impact to the design of energy-efficient stadiums, innovations in sports equipment are diversifying to align with global sustainability goals. Cutting-edge developments include biodegradable materials, solar-powered facilities, and water-saving technologies, each contributing to minimizing ecological footprints across the sports industry. By examining these advancements, we uncover how green patents not only spur technological advancement but also foster a culture of environmental stewardship among sports manufacturers and stakeholders.

Introduction

Among the various countries worldwide, such as China, Kenya, and Sri Lanka, India stands as a significant player. In 2016, China and India collectively accounted for over 60% of the world’s total tea production. Furthermore, India holds the distinction of being the foremost producer of black tea, while China and Japan lead in green tea production. In India, Assam and Darjeeling are recognized as the primary states for tea production, while the Nilgiris and North-East regions also contribute significantly, playing a crucial role in boosting the country’s economic growth.

Assam annually produces over 400 million kilograms of tea, making it the largest tea-growing region globally.Assam has the world’s biggest tea plantations, which are important for India’s economy. The state is near the Brahmaputra River and shares borders with Bhutan, Bangladesh, and Myanmar. Because of its geographical location, this region encounters significant rainfall, especially during the monsoon season, with daily precipitation reaching as high as 250 to 300 mm (10 to 12 inches).A daytime temperature reaches to around 36 °C (96.8 °F), fostering greenhouse-like conditions of intense humidity and heat. The unique malty flavor for which Assam tea is renowned is shaped by the pivotal role played by its tropical climate.

Introduction

Intellectual Property emerged in new type of property referring to creation of the mind in today’s globalized world. While IP such as copyrights, patents, and trademarks are centuries old, but the extension of IPRs to living beings and knowledge related to them is relatively recent. Similarly Intellectual Property Rights (hereafter IPRs) mean legal protection to protect data from new inventions. In exchange for being required to reveal the formula or strategy underlying the technique, these rights enable the owner to stop imitators from commercializing the inventions or processes for a limited time. Biological Diversity refers to all kinds of living organisms found in an area which maintain balance and support life hence may be called as the cornerstone of sustainability of all living creations i.e. the hallmark of the life of living beings since origin. In general, all organisms, including flora and living things, microbes, and their ecosystems, are together referred to as biodiversity.

Introduction

The term “green intellectual property” (IP) is used to describe the legal protections afforded to environmentally friendly innovations. It’s a strategy for saving the planet by stimulating development of environmentally friendly products and methods. For a very long time, plastic consumption has been a huge environmental problem. A report on single-use plastics has been released by the United Nations Environment Programme (UNEP), outlining steps towards environmental sustainability. This research analyses the efforts made at the national, state, and local levels to reduce the usage of disposable plastics. Policymakers considering restricting the manufacturing and use of single-use plastics may find the insights it presents helpful. In 2015, the United Nations General Assembly established the Sustainable Development Goals (SDGs) as part of the 2030 Agenda for Sustainable Development. By 2030, the world’s population should be free of poverty, the planet would be in good shape, and people would live in peace and prosperity. Several of these targets address plastic use; for example, 12: Responsible Consumption and Production, 13: Climate Action, 14: Life Below Water, and 15: Life on Land.

Introduction

Green Intellectual Property Rights (IPR) is a relatively new and evolving concept that emerged in response to the growing global environmental challenges, including climate change, biodiversity loss, and resource depletion. It is an intersection between traditional intellectual property rights and environmental concerns, aiming to promote and protect innovation and technologies that have a positive impact on the environment and contribute to sustainable development.

The concept of Green IPR gained momentum as the world recognized the need for sustainable practices and solutions to address the adverse effects of industrialization and economic growth on the environment. Intellectual property rights, such as patents, copyrights, trademarks, and trade secrets, have long been used to incentivize and protect innovations in various fields. However, the conventional application of IPR did not explicitly consider environmental considerations.

With the rise of environmental consciousness and the acknowledgement of the limited nature of natural resources, there was a call for integrating environmental sustainability into the intellectual property framework. The idea behind Green IPR is to encourage the development and dissemination of eco-friendly technologies, products, and processes while safeguarding the rights of innovators and creators.

Introduction

As a new decade begins, the effects of climate change are being felt all around the world. Storms, floods, droughts, and wildfires are examples of events that may already be linked to climate change and that are expected to occur more frequently and intensely as well as the destruction they inflict virtually every day. The state of the world’s climate is a serious issue that requires attention. In order to create a future that is more environmentally friendly, addressing this issue is urgently required, and everyone must take this into consideration as their shared goal. Since technology is increasingly being seen as a part of the outcome.

To this end, the strengthening of national innovation systems and ensuring that people have access to effective IPPI management programmes need to be stepped up with a view to improving research and development in technologies, products and services which are needed for transformation into a more environmentally sustainable future. This crisis can’t be solved, unless there is a breakthrough technology that will make the goals achievable. This is why innovation in the field of “green” technologies will be needed and intellectual property rights will play an important role. Intellectual property rights may ensure that technological progress can be sold to allow for the continuation of research and development investment but they could also cause problems and constraints. The impact and opportunities that “Green IP” can have are therefore considerable. Regardless of their distinctions, “Green IP” will have an impact on companies from different industries, sectors, and locations. The consumer goods sector needs to improve how they go about changing the specifications for designing products that can be easily recycled and repaired.

Sampling methods and procedures of packaging material.

Introduction

The objective of sampling of a packaging material is to obtain a representative sample of a whole lot for the required testing and/or grading. It is expected that the test results and grading will reflect the average quality of the PM from which the sample was taken.

Principle

The sample techniques and processes outlined in this publication are grounded upon scientific principles. Since the validity of any later test result depends on the quality of the sampling and the information given with the sample, the sampler is essential to the process of selecting lots for testing and/or grading.

Every PM in the population being sampled has an equal chance of being selected, according to the random sampling principle. Usually, the sample size that is tested is very small in relation to the size of the lot that it represents. The sample must be taken carefully and in a way that gives assurance that it is genuinely representative of the lot. Similarly, in order to reduce the composite sample, all necessary.

Objective

After performing this experiment, you will be able to learn:

Water vapour transmission rate of packaging material

Introduction

Moisture Vapor Transmission Rate (MVTR), also known as Water Vapor Transmission Rate (WVTR), measures the rate at which water vapor passes through a material. MVTR is crucial in various industries where moisture control is vital. For example, moisture-sensitive foods and pharmaceuticals are packaged using materials with controlled MVTR to ensure quality, safety, and shelf life. In the textile industry, MVTR serves as a measure of breathability, enhancing comfort for outdoor clothing. In the building materials industry, managing moisture barrier properties in architectural components helps maintain appropriate moisture levels in the internal spaces of buildings. Various techniques are used to measure MVTR, ranging from gravimetric methods that assess moisture gain or loss by mass to advanced instrumental techniques capable of measuring extremely low transmission rates. It's important to note that special care must be taken when measuring porous substances like fabrics, as some techniques may not be suitable.
