INTRODUCTION

Orchids are the most beautiful flowers in God’s creation and have conquered the cut flower industry all over the world during the last few decades. They are most pampered of the plants, occupy top position among all flowering plants and are valued for cut flower production and as potted plant. They are known for their beautiful flowers, which exhibit an incredible range of size, shape and colour, long life of flowers on the plants and an amazingly long keeping quality which no other plant can claim.

Orchids are excellent for garden and can be grown in beds, pots, baskets, split hollows of bamboo pieces, etc. They are also suitable for interior decoration and remain fresh for many days. Before their aesthetic qualities were exploited, orchids were grown for their tubers which were considered as aphrodisiac. The leaves of Vanda roxburghii have been used against rheumatism in older days in India. Habenaria, a terrestrial genus of orchid also possess medicinal properties. Vanillin produced from Vanilla planifolia is used in flavouring industries. Orchids are used in indigenous system of medicine, particularly Ayurveda. Many of the orchid species contain alkaloids, which are important secondary metabolites. From Dendrobium nobile dendrobine and nobilonine are extracted. Similarly, laburnine from Liparis bicallosa, malaxine from Malaxis congesta and phalaenopsine from Phalaenopsis mannii are extracted. Pseudobulbs of Cymbidium madidum and Dendrobium speciosum are used as food.

Orchid industry in India is not as old as the cultivation and trade of other flowers. Our position in export market is very low as compared to south-east Asian countries like Thailand, Malaysia and Singapore, where orchid growing has become a multi-million dollar industry.

Abstract: Orchids, one of the largest commodities in international cut flowers and ornamental plant market, in which genera Cymbidium, Dendrobium, Phalaenopsis, and Vanda are most traded. Orchids occupy prime position among ornamental plants of the modern world. Both warm and cool temperature cultivars are grown in vitro germinated seeds or clones. Breeders have created polyploid cultivars (amphidiploids, triploids) which have greater flower number/raceme, large flowers and other valuable traits. Numerous genes have been identified in the genus with some sequenced genes being used to create genetic transformants. Genome breeding and wide crosses are routinely used to create new genetic variability. Future crop ideotypes are proposed to continue transformation of this crop during the next millennium.

Introduction

Orchids are the most beautiful flower and have conquered the cut flower industry all over the world. They are valued for cut flower production and as potted plant. Their beautiful flowers varied in size, shape and colour, long life of flowers on the plants and an amazingly long keeping quality which no other plant can claim.

Many of orchids are source of important secondary metabolites as given below.

Vanillin produced from Vanilla planifolia is used in flavouring industries.

Dendrobine and nobilonine from Dendrobium nobile.

Laburnine from Liparis bicallosa.

Malaxine from Malaxis congesta.

Phalaenopsine from Phalaenopsis mannii.

Orchid is a valuable flowering plant belongs to family Orchidaceae. It is considered that the family recognise for maximum number species ranged between17,000 and 35,000 worldwide (Garay 1960; Willis 1973). The word orchid is derived from a Greek word orchis for testicle because of the shape of the root tubers in some species of genus Orchis. India is a reservoir of 1300 orchid species from 184 genera, accounts for nearly 7 per cent of worlds orchids genetic diversity (Arora, 1983; Rampal and Nagrare, 2006) and 1150 species belonging to 164 genera (Satish Kumar and Manilal, 1994) of which about 800 species are found in the North Eastern region of the country (Nagaraju et al., 2006). Apart from species, more than one lakh hybrids developed in orchids. It is found all over the world from tropical to temperate and even alpine region. People always think that orchids are epiphytic only but it is not. It can grow in soil as terrestrial, on tree trunk (epiphytic) and on dead organic matter (saprophytes) and on rocks (lithophytes). Orchids produce unique flowers, affluent for their uniqueness in shape, size and colour, exquisitely attractive; remain fresh condition for long period of time in comparison to other flowers. Vase life of its flowers varied among species and hybrids ranged up to 40-45 days. Orchids are cultivated for trade of orchid species, cut-flowers, potted plants, flower basket, bouquet, stage decoration in high profile meets and functions and also used in many other value-added products (Kuehnle 2007). Many orchid species are used as food like Cymbidium hookerianum, Dendrobium chrysotoxum, D. kingianum, D. cathenatum and many more (Singh et al., 2016), spices (Vanilla planifolia and V. pompona) and medicinal uses (Dactylorhiza hatagirea, Flickingeria macraei, Vanda tessellata and Dendrobium macraei as reported by Ram Pal et al., 2020). The most popular and commercially cultivated genera are: Cymbidium, Dendrobium, Oncidium, Phalaenopsis, Vanda, Paphiopedilum, Mokara, Arundina, Paphiopedilum, Ascocenda and Cattleya in the country and even in the world.

Orchids represent a premium segment of commercial floriculture because of their distinctive flowers, long vase life and high market value. This chapter introduces major commercial orchid groups, including Dendrobium, Cymbidium, Cattleya, Phalaenopsis and Paphiopedilum. It discusses botanical features, climate requirements, growing media, propagation, tissue culture, planting, nutrition, irrigation, shade management and greenhouse production. Important pests, diseases and physiological problems are covered along with harvesting, grading, storage and postharvest handling. The chapter also includes commercial standards and cultivar characteristics, making it useful for understanding the specialized management required for high-value orchid production and export-oriented floriculture.

As milk to a cow or fruit to a tree, ore is to Earth Sciences. Different academic and scientific aspects of geology are of no consequence to a common man. Ores and ore minerals from which valuable constituents could be extracted profitably is what the world is after- be it the continental masses, oceanic depths, desolate icy Antarctic tracts or now, even other planets of the solar system. The subject of economic geology is thus a subject of greatest interest among other natural sciences.

This last section will dwell on the theme of metallic and non metallic ore deposits. The first chapter begins with fundamental definitions, signifying the importance of minerals in human affairs. It also looks at ore minerals against the background of average crustal composition and presents a glossary of important terms in economic geology. The second chapter is a lengthy chapter devoted to the ways ore deposits are formed ( ore genesis). Broadly, the processes are described under two categories, the internal processes and the surface processes. Fuel minerals are taken separately towards the end of this chapter. Chapter III briefly introduces the relationship between location of minerals deposits to the revolutionary theme of global tectonics which attempts to answer why a mineral deposits occurs where it occurs.

Lastly, the fifth chapter exclusively deals with the facts and figures of the Indian Mineral Industry presenting recent available data of resources, production, import, export and future prospects. It also gives a brief introduction to the important geo-scientific organizations of the country.

An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. However, sulphuric acids, containing the group –SO₂OH, are relatively stronger acids. Alcohols, with –OH, may also act as weak acids. Some other groups may also act as weak acids viz. thiol group and phenol group. In biological systems, organic compounds containing these groups are generally classified under organic acids. Some common organic acids are lactic acid, acetic acid, formic acid, citric acid, oxalic acid, uric acid, propionic acid and butyric acid. Organic acids have been used for decades in commercial compound feeds, mostly for feed preservation, for which formic and propionic acids are particularly effective. Since the ban of antibiotic growth promoters in many countries, organic acids have been used increasingly, not only because of their preservative qualities, but also for their nutritive properties. Organic acids and their salts are generally regarded as safe and have been approved by most member states of EU to be used as the feed additives in animal production.

Organic farming is getting more and more popular as a farm practice. Although most agricultural land is still processed through conventional farming, the demand for organic agriculture and organic crops is constantly increasing. Organic farming is defined in a variety of ways. The majority of them argue that synthetically manufactured fertilisers and pesticides are not allowed in organic farming. This is right; yet, organic farming encompasses much more. Organic farming is founded on unique qualities as a wholly natural and sustainable farm management technique. To put it another way, organic farming is both an agricultural practise and a philosophy of cooperating with nature.

Climate change mitigation is urgent, and adaptation to climate change is crucial, particularly in agriculture, where food security is at stake. The gases contributing to the greenhouse effect mainly include carbon dioxide (CO₂), nitrous oxide (N₂O) and methane (CH₄). These gases have varying global warming potentials, which can be expressed in CO₂ equivalents.

Agriculture, currently responsible for 2030% of global greenhouse gas emissions (counting direct and indirect agricultural emissions), can however contribute to both climate change mitigation and adaptation. The main mitigation potential lies in the capacity of agricultural soils to sequester CO₂ through building organic matter. This potential can be realized by employing sustainable agricultural practices, such as those commonly found within organic farming systems. Examples of these practices are the use of organic fertilizers and crop rotations including legume leys and cover crops. Mitigation is also achieved in organic agriculture through the avoidance of open biomass burning, and the avoidance of synthetic fertilizers, the production of which causes emissions from fossil fuel use.

Organic agriculture is associated with higher carbon sequestration as many organic practices help to improve soilquality and carbon sequestration. The most common organic practices that increase soil organic carbon are the use of organic fertilizers (such as the composted waste products from livestock husbandry), crop rotation involving legumes and the planting of cover crops.

Organic farming offers several ways to mitigate climate change when compared to conventional agriculture:

Primarily, organic farming, through its key practices of organic fertiliser use and crop rotations with forage legumes, tends to increase soil organic carbon levels resulting in carbon sequestration.This contributes to climate change mitigation, as it absorbs CO₂ from the atmosphere and stores the additional carbon in the soil. However, depending on soil type and climatic conditions, this process usually comes to a halt after some decades, when soil organic carbon levels have reached a new equilibrium and soils arethus saturated with respect to organic carboncontents. Furthermore, this storage of organiccarbon is reversible and the carbon can again be released into the atmosphere as carbon dioxide when switching to unsustainable practices.

Agriculture is an important factor for human civilization as it not only provides food, feed for the livestock, fibre, fuel and industrial raw material but also supports the livelihood of a wide range of world population. Besides, it shows its prominent presence in the economy of the developing countries. Being a developing country, agriculture is the largest sector in India where about 54% of the population is engaged. The growth of agriculture in India during last seven and half decades (after independence) is quite remarkable in terms of sufficient food-grains production as well as in achieving self-sufficiency in food production. The task to achieve it was not so easy.

Introduction

Organic agriculture implies growing of agricultural crops and animal husbandry components while not chemical plant food, weed killer and pesticides used. An agricultural practice followed in organic farming squarely measure ruled by the principles of ecology and squarely measure amongst the ecological means that.

Organic agriculture could be a production system that avoids or mostly excludes the employment of synthetically combined fertilizers, pesticides, growth regulators, placental feed habit-forming and genetically changed organisms. Organic farmers admit crop rotation, inexperienced manures, compost, biological blighter management, and mechanical cultivation to keep up soil productivity and management pests as way as doable and practicable. Organic agriculture could be a distinctive production management system and key issue of maintenance of agricultural property that promotes and enhances agro-ecosystem health, together with multifariousness, biological cycles and soil biological activity, and this is often accomplished by victimization on-farm science, biological and mechanical ways in exclusion of all artificial off-farm inputs during this context, a serious thrust towards organic cultivation, however, would require variety of alternative initiatives and infrastructural support. Active involvement in learning crops and their diseases, development of organic manure, natural pesticides, coaching of farmers, and provision of storage and property square measure all vital areas to appear into.

Organic farming has become progressively vital in agriculture given the rising variety of issues that use of chemical fertilizers and pesticides squarely measure throwing up GM (genetically modified) crops could give a wonderful yield however their long-run effects square measure hitherto untested and other people aren’t quite able to trust these foods excepting for this, there has been a big rise within the demand for organic food across the globe. Promoting these organic-farming techniques solely leaves India best poised to take advantage on the export potential of those foods.

Abstract

Women empowerment is a buzz word of every platform starting from household issues to national politics. The best way to empower women is to make them economically self-reliant through entrepreneurial activities. In India agriculture is mainstay of the country and 70 percent women are farmers, so the best measure to empower them is through entrepreneurship in agriculture and allied sectors particularly organic agriculture as India currently holds a prominent position among 172 countries that actively practice it. At present, the country is home to more than 8, 50,000 organic producers, 699 processors, 669 exporters, and 7, 20,000 hectares under cultivation. Merely with 0.4 per cent of total agricultural land area under organic cultivation, India has attained global standing which infers that this industry still has a long way to go in terms of growth and opportunities for socio-economic development. Organic Food industry has been experiencing steadfast growth in past few years in India in spite of several challenges at producer, processor and consumer levels. With its annual turnover of Rs 4000 crore and annual growth rate of 25%, the country’s budding organic food market is transforming into world’s fastest growing organic food market with expected turnover of 10,000 crore by 2020. There is drastic change in consumer behavior and spending patterns in the country which has opened avenues for organic food industry at the national level besides export. This highscale opportunity is driven by the fact that organic food consumption is not even 0.1 percent of India’s $300 billion annual food consumption. Likewise, India’s share in the $100 billion global organic food market is less than 0.2 percent. Further, the scope of the opportunity is also driven by the increasing variety of organic foods hitting the market and the emergence of e-commerce as a channel in which to sell the product. India today is on the threshold of organic revolution where women participation will act as booster but need to be supported by Govts and technical institutions. Barriers to improving women’s agency include widespread deficiencies in policy support to women, and in fact to the organic farming sector as a whole. It is necessary to increase women’s research presence in organic research institutions (including at the higher levels). To enable women to conduct research in the field, it is important to allow women to set research agendas, and to work with their research needs and priorities. Food security as a priority for organic agriculture involves women’s empowerment since they hold a central role in providing nutrition for the household.

Abstract

Organic farming has proved to be effective technology for socio-economic empowerment of Indian farmers as it imposes positive changes in social factors in the local communities. There is tremendous scope of export, entrepreneurship and employment opportunities in organic farming in India. Local, regional, national and global markets are developing sinks for organic products. Organic crop production is sustainable and has positive impact on the ecology and socio-economic status of the peoples. Various socio-economic factors influence the farmers’ choice to adopt organic cultivation. Several threats and weaknesses exist. Hence, there is a need to address the weaknesses of the organic system by integrating it with innovative tools of marketing and ICTs so that there is alignment in demand- production-supply so concerted efforts are needed to establish production-consumption linkages through PPP mode. It will offset threats of organic farming thereby making it more remunerative and promising. The existing evidences suggest greater research efforts in this area are required. There is need to identify the gaps between the adoption of techniques of organic farming and remove them by strengthening production-consumption and marketing linkages. Moreover, it is important to assess and analyze the status of organic farming and feasibility to different sustainable practices in different production systems and farming situations across the country for promotion of this value added entrepreneurship.

Introduction

Organic farming is a comprehensive approach to production management that promotes and improves Agro-health, ecosystems including biodiversity, biological cycles, and soil biological activity. It prioritizes management approaches above off-farm inputs, and agronomic, biological, and mechanical farming procedures are used rather than synthetic resources (Ajibade, Ayinde, and Abdoulaye 2020). The term “organic farming” refers to a production technique that excludes the use of artificially formulated fertilizers, pesticides, or growth regulators for agronomic practices or the use of different chemicals for livestock production, i.e., feed additives, growth promoters and antibiotics, etc. (M. Singh 2021).

The terms such as organic, natural, biological, biodynamic, altemative and sustainable farming have entered the agriculture vocabulary. Inspite of these differences in terminology, basically identical ideologies, ideas and technologies are reflected. The common objectives of all the system are to develop farming methods to restore, maintain or build-up soil productivity, to protect the environment instead of causing pollution, produce safe and healthy food, and preserve or help the small farmer.

In Japan, the farmers study the nature, learn from it and apply the knowledge on their farms. For instances growing plots should also be mulched with straw or plant residues, this imitates the conditions in natural forest where ground is never bare. Instead of using pesticides, strong herbs or plants can be grown around vegetable plots to ward off the insects. To keep the soil health natural, organic fertilizers are used. Soil microorganisms and earthworms take care of the processes involved in decomposition and mineralization of the organic substances, fix atmospheric nitrogen, solubilise insoluble forms of phosphate and produce natural growth promoting substances and antibiotics,

The concept of sustainable agriculture is gaining acceptance and momentum because of rapid degradation of natural resources, increase in the cost of production in conventional agriculture system and deterioration in the quality of rural life caused by environmental pollution. Moreover it is risky and uneconomical to practise conventional agriculture in over 70 percent of the cultivated area in India which is presently under rainfed farming. Much of the know how to practice organic farming models has rested on the individual farmers till now. They however do not have the benefit of appropriate technology and scientific information and also institutional support to ensure success of the new farming system.

Organic Farming

The FAO/WHO Codex Alimentarius Commission defines organic farming as “a unique production management system which promotes and enhances agro- ecosystem health, including biodiversity, biological cycles and soil biological activity, and this is accomplished by using on-farm agronomic, biological and mechanical methods in exclusion of all synthetic off-farm inputs”. It is a certification of a production system as opposed to the certification of a product. For a product to be certified organic, all operators in the product chain, including farmers, processors, manufacturers, exporters, importers, wholesalers and retailers must be certified organic. The establishment of organic animal/poultry husbandry requires a specific period called as “conversion period”. This period is the time taken between the start of the organic management on farm and certification of livestock farm and its product. Changing from conventional to organic management system for livestock enterprises requires a careful and gradual approach. It is learnt that global organic product has increased 20% annually over the past 10 years. Though Australia, European Union and USA are leading organic producers, a recent study indicated that developing countries including India are also adopting the system and marching ahead.

Organic Poultry Farming

Definition and Overview

• The FAO/WHO Codex Alimentarius Commission defines organic farming as a “holistic production management system that promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity, using non-farm agronomic, biological, and mechanical methods, excluding all synthetic off-farm inputs.”

• Organic chicken farming involves raising chickens in a natural, humane environment outside of a conventional chicken house, feeding them organic feed (free from synthetic fertilizers, pesticides, and GMOs), and avoiding the use of antibiotics or growth hormones.

• The main goal is to produce healthier, environmentally friendly chicken products while ensuring high animal welfare standards.

• Conversion Period: Transitioning a conventional poultry farm to an organic one requires a certain period called the “conversion period.”

• Organic poultry farming necessitates the use of indigenous chicken varieties managed organically, allowing the birds to express their natural behavior.

• Growing Popularity: The demand for organic poultry meat is increasing due to heightened health awareness among consumers. Chicken, in particular, has become a key organic meat due to its shorter production cycle.

Agricultural sector, with the technological advancements, is also contributing to global climate change, loss of biodiversity and degradation of resources. Further, there is a serious global concern about chemical residues, healthy food and healthy planet earth. Organic and natural farming are acclaimed to be the best alternative non-chemical production pathways to reverse the ill effects of modern agriculture. However, these systems are not contemplated to meet the food security and other requirements of ever-growing human population, particularly in developing countries. In this chapter, based on the available and documented protocols and production practices of these systems, the additional research, extension and policy needs to strengthen these production pathways to attain economic, ecological and social sustainability are discussed while considering the Sustainable Developmental Goals (SDGs) of United Nations.

In general, any business directly involved in food production can be certified, including seed suppliers, farmers, food processors, retailers and restaurants. Requirements vary from country to country, and generally involve a set of production standards for growing, storage, processing, packaging and shipping organic certification ensures:

• Avoidance of synthetic chemical inputs (e.g. Fertilizer, pesticides, antibiotics, food additives, etc) and genetically modified organisms;
• Use of farmland that has been free from chemicals for a number of years (often, three or more);
• Keeping detailed written production and sales records (audit trail);
• Maintaining strict physical separation of organic products from non-certified products and
• Undergoing periodical on-site inspections.

In some countries, certification is overseen by the government, and commercial use of the term organic is legally restricted. Certified organic producers are also subject to the same agricultural, food safety and other government regulations that apply to non-certified producers.

1.0 INTRODUCTION

The most significant factors distinguishing organic farming from eco-farming are the existence of production standards and certification procedures. Certification of organic farming is the procedure by which a written assurance is given by the certification agency that a clearly identified production or processing system has been methodically assessed and conforms to the specified requirements. It is a process certification rather than a product certification. Certification and labelling is usually done by an independent body to provide a guarantee that the production standards are met.  In case of organic products, certification is an acknowledgement that the products are produced according to organic production standards of certification bodies or associations or of the country. Organic production system is a land use system in accordance with set standards to the location specific conditions by integrating practices that foster cycling of resources, promoting ecological balance and conserve biodiversity. The prime principles of organic farming are,

Organic food sales increased steadily from the late 20th century. Greater environmental awareness, coupled with concerns over the health impacts of pesticide residues and consumption of genetically modified (GMO) crops, fostered the growth of the organic sector. Realizing the benefits of organic food, especially after COVID-19, consumers are also demanding organically grown food and fiber and are willing to pay premium price. But to tap the market, there is an inevitable need for certification. Recently launched Food Safety and Standards (Organic Food) Regulation, 2017 mandates that all food products sold as organic must be certified and comply the basic requirements of the Act. The organic food offered or promoted for sale shall also comply with all the applicable provisions of either National Programme for Organic Production (NPOP) or Participatory Guarantee System for India (PGS India). Organic certification is a process certification. The requirement to confirm that the product is organic include labelling on the package and traceability for both domestic and export needs to be understood. For import and export of organic produce, transaction certificate issued by an Accredited Certification Body is required. These requirements are essential for fresh and processed food items. In this chapter, we tried to eloborate the process and procedures for organic certification.

Organic certification is the procedure by which the accredited certification Body by way of a Scope Certificate assures that the production or processing system of the operator has been methodically assessed and conforms to the specified requirements as envisaged in the National Programme for Organic Production (NPOP).

The NPOP provides for Standards for organic production, systems, criteria and procedure for accreditation of Certification Bodies, the National (India Organic) Logo and the regulations governing its use. The standards and procedures have been formulated in harmony with other International Standards regulating import and export of organic products.

In India, there are two accreditation systems for authorizing Certification and Inspection agencies for organic certification. National Programme on organic Production (NPOP) promoted by Ministry of Commerce is the core programme which governs and defines the standards and implementing procedures. National Accreditation Body (NAB) is the apex decision making body. Certification and Inspection agencies accredited by NAB are authorized to undertake certification process. The NPOP notified under FTDR act and controlled by Agricultural Processed Foods Export Development Authority (APEDA) looks after the requirement of export while NPOP notified under APGMC act and controlled by Agriculture Marketing Advisor, Directorate of Marketing and Inspection looks after domestic certification. Currently 20 certification agencies have been authorized to undertake certification process.

National Programme on Organic Production

National Program on Organic Production (NPOP) was launched during 2001 under the Foreign Trade & Development Act (FTDR Act). The document provides information on standards for organic production, systems criteria, and procedures for accreditation of Inspection and Certification bodies, the national organic logo and the regulations governing its use.

Introduction 
In the constantly changing field of environmental science and technology, researchers are increasingly adopting eco-friendly and sustainable approaches to address the widespread problems of contamination and pollution. A potential perspective that demonstrates a harmonic fusion of nature and nanotechnology is the creation of nanoparticles (NPs) utilizing secondary metabolites derived from plants. Due to their low toxicity, catalytic effectiveness, and biocompatibility, iron oxide nanoparticles (IO NPs) and silver oxide nanoparticles (Ag2O NPs) have become essential materials for environmental remediation. The production of these NPs depends heavily on secondary metabolites found in plants, including flavonoids, polyphenols, and tannins. These bioactive substances function as reducing, stabilizing, and capping agents during the creation of NPs, essentially serving as natural biofactories (Mittal et al., 2013) (Figure 1). The reduction of metal ions to NPs is driven by organic reaction mechanisms, such as redox reactions mediated by these metabolites, guaranteeing an environmentally benign and effective fabrication method. (Jadoun et al., 2021) Additionally, the incorporation of organic groups to the NPs’ surface, these metabolites greatly increases their catalytic activity and selectivity. IO NPs synthesized from plant extracts, particularly in forms like magnetite (Fe2O4) or hematite (Fe2O3), which exhibit special surface characteristics and remarkable magnetic behavior (Logeswari et al., 2015). These qualities guarantee a low environmental effect by making it easy to recover and recycle them after application. The organic functional groups obtained from plant metabolites give them increased stability and dispersibility, which increases their efficacy in remediation methods. Similarly, Ag2O NPs generated from plants display exceptional catalytic and antibacterial capabilities, expanding their use in combating environmental contaminants (Ettadili et al., 2022). It is essential to develop materials that meet stringent performance and sustainability criteria. By following green chemistry principles and guaranteeing non-toxicity, biodegradability, cost-effectiveness, recyclability, and ease of recovery, plant-derived NPs meet this requirement (Bao et al., 2021). These qualities maximize its usefulness while reducing ecological problems. Optimizing nanomaterials for practical uses is still difficult, though surface engineering and creative synthesis methods are required to address problems such as aggregation, instability, possible toxicity, and high recovery costs. Organic functional groups derived from secondary metabolites play a crucial role in this context, stabilizing NPs and enhancing their selectivity and activity for specific remediation tasks (Jebali et al., 2011) from plant extracts are examined in this chapter. It highlights the organic reaction processes involved, the critical role of secondary metabolites which play in the synthesis process and, on the other hand, the surface functionalization plays in boosting their catalytic activity for environmentally friendly remediation (Jeevanandam et al., 2022).

The organic constituents of soils or soil organic matter is the most essential components of soil consisting of plant and animal residues at various stages of decomposition, cells and tissues of living or nonliving organisms and the substances synthesized by their decomposition. Soil organic matter exerts profound effect on soil productivity as it acts as source and sink of plant nutrients especially nitrogen and sulphur. It also involves in major biochemical processes to transform or release of plant nutrients into their available forms. Thus, it plays vital role in soil fertility maintenance, through increasing cation exchange capacity and improving soil physical properties, such as bulk density, aggregation, water retention capacity and also supports all kinds of biological activities in soil. The soil organic matter mostly concerns only with dead organic fractions formed from the decomposition of original plant and animal residues using as a source of food and energy by the soil microorganisms. It can be distinguished into –

Organic crop production is a cornerstone of sustainable agriculture, emphasizing environmental stewardship, biodiversity, and soil health. By eliminating synthetic pesticides and fertilizers, organic farming fosters resilient ecosystems and enhances soil fertility through natural processes such as composting and crop rotation. This method not only reduces pollution and greenhouse gas emissions but also promotes the conservation of water and energy resources. Organic crop production supports biodiversity by creating habitats for various species, contributing to a balanced ecosystem. Moreover, it offers health benefits by providing consumers with produce free from harmful chemicals. As global concerns about climate change and food security grow, organic farming represents a viable path towards a sustainable future, ensuring long-term agricultural productivity and ecological balance.

Organic farming is a crop production method respecting the rules of the nature, targeted to produce nutritive, healthy and pollution free food. It maximizes the use of on -farm resources and minimizes the use of off – farm inputs.

The general guidelines on organic production of crops are prepared based on National Programme for Organic Production (NPOP) launched by Government of India. These guidelines enable the growers to attain more or less the same level of the productivity of conventional farming within a few years and at the same time maintain the fertility of the soil and protect the ecological balance.

From an ecological perspective all organisms are part of nature, irrespective of what they do. To a farmer, all organisms that reduce the yields of their crops are considered pests, diseases or weeds. Insects, birds or other animals are also pests whenever they cause damage to crops or stored produce. Fungi, bacteria and viruses are also recognized as disease causing organisms when they lead to conditions that interrupt or modify the vital functions of growing plants or stored produce. All unwanted plants that grow within crops and compete with them for nutrients, water and sunlight are considered weeds. Such plants can also be hosts for pests and diseases.Presence of these organisms in crop fields is not a problem until their numbers increase beyond a level where they attack, and cause substantial reductionin field crop yields or quality of harvested and stored produce.

The organic approach to plant pest, plant disease and weed management makes reference to the four principles of organic agriculture: the principle of health, the principle of ecology, the principle of fairness, and the principle of care. Generally, organic farmers aim at sustaining and enhancing the health of their soils, plants, animals, humankind and—in the widest sense—the planet. The health of individuals and communities cannot be separated fromthe health of ecosystems. Therefore, by providing healthy soils and a diversified natural environment, farmers are able to produce healthy crops that foster the health of animals and people.

Healthy plants are also able to resist and tolerate physiological disruption and damage from disease-causing organisms and pests. Thus, organic farmers aim at optimizing the growing conditions for their crops to make them strong and competitive. At the same time they encourage natural control mechanisms to prevent pests, diseases and weeds to develop in a way that they cannot damage the crops. They, therefore, give priority to preventive measures to prevent and limit the spread of infections, instead of relying on direct control measures. Direct control measures are mainly applied when pathogens have already developed.

12.1 Introduction
Guava (Psidium guajava L.) is an important tropical and subtropical fruit crop, valued for its high nutritive content, processing potential, and adaptability to diverse agro-climatic conditions. In recent years, there has been a growing shift from conventional chemical-intensive farming towards eco-friendly and sustainable production systems. Organic farming in guava has gained importance due to its ability to enhance soil fertility, improve fruit quality, and reduce environmental degradation. The integrated use of organic manures, biofertilizers, and reduced chemical fertilizers has been shown to optimize yield while maintaining ecological balance.
12.2 Role of Organic Manures
Farmyard manure (FYM), vermicompost, poultry manure, and neem cake are commonly used organic amendments in guava cultivation. These materials improve soil physical properties, enhance microbial activity, and release nutrients gradually. Muhammad et al. (2000) reported that a combined application of FYM with NPK fertilizers significantly increased fruit size, weight, and total yield in guava. Similarly, Ebrahiem and Mohamed (2000) observed that FYM application in ‘Balady’ mandarin improved fruit set and yield, demonstrating the broad utility of organic amendments across citrus crops.

25.1 Introduction

There has been a recent increase in the consumption of organic food, particularly in developed countries. Consumer awareness is growing in terms of organic food products in recent years as almost all the food ingredients are grown under intense production systems which utilize lot of chemicals and pesticides to control the pests and diseases. Organic farming can be defined as an approach to agriculture where the aim is to create integrated, humane, environmentally and economically sustainable agricultural production systems producing acceptable levels of crop, livestock and human nutrition, protection from pests and diseases, and an appropriate return to the human and other resources employed.

Introduction

The green revolution which initiated in India during 1960’s to 1980’s was an attempt to overcome the then prevailing threats of food scarcity and lack of foreign exchange. The food scarcity was a result of severe drought which engulfed the country as well as the political situation it had to face after its short period of gaining independence (Reddy, 2010). The only way out to overcome the acute food scarcity was intensive agriculture, with the use of high yielding varieties, chemical fertilisers and pesticides which heavily boosted agriculture production in India. The remarkable increase in production and productivity resulted in non-judicious use of chemical inputs to extract the maximum from the degrading soil. This marked the era of soil, water and air pollution and extreme health hazards to all life forms.

Rachel Carson’s “Silent spring” in 1962 was an insight into the path of DDT the then prevalent pesticide through its effect on the food chain as well as the environment. She was one among the scientists to raise her voice against the indiscriminate use of pesticides. The evident impacts raised concerns over the continued use of chemical inputs (Lairon, 2010). The situation warranted the reduced or limited use of chemicals in agriculture which resulted in an “organic movement”. This caused a slow, but evident shift in the interest of growers and consumers towards organic agriculture for health security, food safety, quality and better returns (Niggli et al., 2007).

This review is an attempt to analyse the various factors affecting the safety and quality of organic food products in comparison with conventional food. Drawing a proper conclusion was a difficult task due to the limited availability of scientific papers published in this aspect, indication of only trends rather than solid proofs and non-revelation of non-significant data regarding related experiments. However, this review could evaluate the positive and negative aspects of organic cultivation and food production from the available data, so as to suggest measures for improving the quality and safety of organic food products.

In India, Mahatma Gandhi known as father of the Nation, deserves for imparting credit as pioneer for organic agriculture by way of promoting farmyard manure, compost and advocating use of night soil to enhance the soil fertility and thereby, crop productivity. Organic agriculture possesses lot of advantages over conventional agriculture, especially in areas having low rainfall and showing low soil fertility (Yadav, 2010). Although APEDA (Agricultural and Processed Food Products Export Development Authority) as an apex body which is working to promote the export of organic food commodities. However, lack of adequate certification facilities and the trainings organized, markets for organic foods inadequate, political and scientific will power are some of the hindrances for operating organic agriculture in India. As human and natural resources are readily available in our country, so there is good scope for organic agriculture farming including organic animal husbandry by adopting proper organic agriculture policies.

Organic farming in India started receiving focused attention from the year 2004-2005 when National Project on Organic farming (NPOF) was launched during 2004, the area under organic farming was 42,000 hectares (Srimathi and Jency, 2014). By March, 2010, it was reached to 1.08 million hectares. In addition to these, 3.40 million hectares was wild forest harvest collection area. Thus, total area under organic certification process by March,2010 was 4.48 million hectares which was increased by 25 folds during last 6 years. In cultivated organic land 7.56 lakh hectares was certified while 3.2 lakh hectares was under conversion. In India, States such as Orissa, Jharkhand, Uttarakhand (Uttaranchal), Himachal Pradesh, Jammu and Kashmir Rajasthan, Gujarat, Madhya Pradesh and Chhattisgarh have been categorized as low or negligible fertilizers consuming states of the country.

Introduction

The Indian literature viz; Vedas and other related books show that ancient Indians used to impart great significance to the gardens and parks. Indian rulers especially, the kings, the princess vis-a-vis affluent people took special interest in making vegetable gardens in the houses and fruit tree gardens in open areas. In those days, it was considered to be the foremost duty of a king to maintain the beautiful gardens in the city and around his palace. It is even said that only he should be revered as an ideal king whose abode is provided with spacious gardens having full of fruit bearing trees (Krishna murthy 2012). As a matter of fact, the gardens also contained pools and tanks adorned with beautiful lotus blossoms, having a number of plants and bushes laden with large number of fragrant flowers etc. Kautilya has included gardens and fields under the term of “Vastu”. So Vastu Sastra or the science of habitation may be taken to stand for laying out of gardens etc; including both horticulture and agriculture.

Organic farm produce is now gaining momentum in the world. People of high status and concerned with health hazards are interested in organic product. Since 1990, the market of organic product has grown reaching a value of Rs 55 billion in 2009 as per the Organic Monitor in the world. The demand has been reflected in increase of land under organic farming which has grown correspondingly at a rate of 8.9% per annum. At present there is approximately 37,000,000 hectare of land under organic farming worldwide. The idea has been percolated to rural areas and the farmers of all kinds are aware of organic farming. In terms of organic land, Australia leads the pack with 11.3 million hectares followed by Argentina (2.8 million hectares) and Italy with more than one million hectares. In Asia, China, India and Japan are the largest organic producers. Japan is the region’s largest market and buys majority of Asia’s production.

Organic farming is increasingly recognized as a sustainable agricultural practice that prioritizes soil health, ecological balance, and long-term productivity. This article explores the intricate relationship between organic farming and soil health, detailing the principles, practices, benefits, challenges, and future prospects. Key organic farming practices such as crop rotation, cover cropping, composting, green manuring, and reduced tillage play crucial roles in enhancing soil structure, fertility, and biodiversity. While organic farming offers numerous benefits, including improved soil fertility, structure, microbial activity, and water management, it also faces challenges like nutrient management, pest control, soil erosion, and weed management. Through case studies and future perspectives, this article underscores the potential of organic farming to contribute to sustainable agriculture and environmental protection, advocating for continued research, policy support, and education to maximize its benefits.

There is no doubt that after independence, particularly during 1966-68, the use of hybrid and composite seeds of various crops, chemical fertilizers and pesticides resulted in an increase in the Indian agricultural output leading to ìGreen Revolutionî. But quite soon, the deleterious effects of farming based on chemical Organic Farming for Sustainable Agriculture 105 methods came to fore.

Sustainable development has caught the imagination and action across the world. Sustainable agriculture is necessary to attain the goal of sustainable development. The word “sustain,” is derived from the Latin sustinere (sus-, from below and tenere, to hold), to keep in existence or maintain, implies long-term support or permanence. As it pertains to agriculture, sustainable describes “Farming systems that are capable of maintaining productivity and usefulness to society indefinitely. Such systems must be resource-conserving, socially supportive, commercially competitive, and environmentally sound”. “Sustainable agriculture is the successful management of resources for agriculture to satisfy changing human needs while maintaining or enhancing the quality of environment and conserving natural resources” (FAO). All definitions of sustainable agriculture lay great emphasis on maintaining an agriculture growth rate, which can meet the demand for food of all living things without draining the basic resources. Over time, the International Alliance for sustainable agriculture and an increasing number of researchers, farmers, policy-makers and organizations worldwide have developed a definition that unifies many diverse elements into a widely adopted, comprehensive, working definition

Introduction

Green revolution played a major role in making several counties self reliant in food production. But modern agriculture has degraded natural resources and made agriculture unsustainable. People are getting enough food, but the food is unsafe. Land, water and air have become polluted. People are suffering from the serious diseases like cancer. An alternate version of agriculture or organic farming that is necessity of the day. People are becoming health conscious day by day. There is good demand for Indian organic food in several countries. Niche areas exist for organic farming in several states of India. The Govt of India has launched several programs to promote organic farming.

Organic farming in groundnut cultivation is gaining global recognition as an environmentally sustainable and socially responsible approach. Groundnut is a versatile crop with high nutritional value and economic importance. This chapter explores the principles and practices involved in organic groundnut farming. It focussed on soil management, organic fertilization, pest, disease and weed management without using synthetic chemicals. This approach minimizes impact on the environment and reduces the presence of pesticide residues in the final produce. Moreover, organic practices help maintain soil health, conserve biodiversity and reduce environmental pollution. Thus, farmers can produce high quality groundnuts and fetch higher price and profits.

1. Introduction

The groundnut (Arachis hypogaea L.) is known by different names such as monkey nut, goober, earth nut etc., and belongs to leguminosae family. It produces flowers above ground but the fruits/pods underground (Sanders, 2003). It can be grown successfully in tropical and sub-tropical regions of the world. Globally, groundnut covers 32.7 M ha with a production of 53.9 MT with a productivity of 1648 kg ha-1 (FAOSTAT, 2021). Among the developing countries, Egypt has the highest productivity of groundnut with 2.70 t ha-1 (Nautiyal, 2001). Globally, India ranks first in groundnut area (5.42 m-ha) and is the second largest producer in the world with 10.1 MT with a productivity of 1863 ha-1 in 2021-22 (agricoop.nic.in). India ranks second next to China (34%) with 19% of world groundnut production in 2021. Gujarat is the largest producer contributing 36% of the total production of groundnut followed by Rajasthan (17%) and Tamil Nadu (7.5%). Groundnut accounts for 18% area and 26.8% production of the total oilseeds in India (CARP, 2022).

Organic farming is the form of agriculture that relies on techniques such as crop rotation, green manure, compost and biological pest control. Organic farming uses fertilizers and pesticides but excludes or strictly limits the use of manufactured (synthetic) fertilizers, pesticides (which include herbicides, insecticides and fungicides), plant growth regulators such as hormones, livestock antibiotics, food additives, genetically modified organisms, human sewage sludge, and nano materials.

There is a need to look for new means to check this menace. Chemical fertilizers are necessary to feed the ever increasing population of the nation but this needs to be supplemented with the organic manures. But organic manures are not available in sufficient quantity. Besides, they alone cannot meet the nutritional requirement of the crops and have to be applied alongwith the chemical fertilizers. Experimental results have shown that if organic fertilizers are applied then chemical use can be brought down to half. This will lead to favourable impact on the soil ecology besides saving large amounts that are being pumped to subsidize the chemical fertilizers.

Organic agriculture is picking up in some parts of our nation and it can generate viable farming option to small and marginal farmers. But short supply of the organic inputs is emerging as one of the major bottlenecks. Vermicomposting of city wastes and farm wastes can generate substantial volume of the organic fertilizer for use in our fields, thereby, helping us to overcome major hurdle in taking up organic agriculture production. This chapter attempts to identify the find out the ways and benefits of practicing organic farming and determines the economics of Vermicomposting technology.

The North Eastern Hill Region is the most suitable area of India for organic agricultural farming because of its numerous advantages. This region is said to be, by and large, organic by default or the farmers of this region are de facto organic producers. Truly, the farmers of this region are using very minimal or not even minimal amount of inorganic inputs like fertilizer and pesticides. Almost in all the seven states of this region, farmers are practicing traditional agriculture for thousands of years. Recently, only pockets of the region, the use of inorganic inputs have been started but the level of use is almost negligible. This low chemical input use (inorganic input) is the biggest strength in term of the possibility of organic agriculture in this hilly region. The conversion period of organic from inorganic agriculture will be much lower and easier in this region as compared to other parts of the country. Further, the conversion process will be much easier due to the readily available huge amount of forest biomass and the residues of diverse livestock population. Moreover, experimental results show that during the transition period, the farmers face the problem of yield losses, but in NE India it was observed that yield loss was minimum, sometimes nil, because farmers of this region are using very low level of inorganic inputs. Additionally, the organic products usually fetch higher prices, nearly 20-25 per cent premium as compared to the conventional products, which, may compensate the problem of yield losses during early period of conversion and thereby increase the level of income.

North-Eastern Hill Region is suitable for growing a number of high value crops and following good agricultural practices for cultivation of these crops are likely to increase farm income substantially. Enabling the state to follow systematic organic farm practices is likely to make the farming profession more remunerative. Present socio economic study indicated that the organic farm practices might be quite favourable particularly for few crops like pineapple, turmeric, ginger and cashew, which have readymade potential.

18.1 INTRODUCTION

Organic farming systems have attracted increasing attention over the last one decade because they are perceived to offer some solutions to the problems currently besetting the agricultural sector. In the western world, organic farming is catching fast (Malik, 2000). Indiscrimpte use of chemical fertilizers, herbicides and pesticides have resulted in environmental and health hazards along with socio-economic problems (Padmadevi, et al., 2008). India is bestowed with lot of potential to produce all varieties of organic products due to its diverse agro-climatic regions. In several parts of the country, the inherited tradition of organic farming is an added advantage. Organic farming is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture “is the successful management of resources for agriculture to satisfy changing human needs while maintaining or enhancing the quality of environment and conserving natural resources”. All definitions of sustainable agriculture lay great emphasis on maintaining an agriculture growth rate, which can meet the demand for food of all living things without draining the basic resources. Organic farming is one of the several approaches found to meet the objectives of sustainable agriculture. Many techniques used in organic farming like intercropping, mulching and integration of crops and livestock are not alien to various agriculture systems including the traditional agriculture practised in countries like India. However, organic farming is based on various laws and certification programmes, which prohibit the use of almost all synthetic inputs, treated seeds and health of the soil is recognized as the central theme of the method. Adverse effects of modern agricultural practices on the farm resources and health and over all survival of living being have been well documented all over the world. Application of technology, particularly in terms of the use of chemical fertilizers and pesticides has been serious concern. Their negative effects on the environment are manifested through soil erosion, water shortages, salination, soil contamination, genetic erosion, etc. Organic farming has the potential to provide benefits in terms of environmental protection, conservation of non-renewable resources and improved food quality. It is very important to maintain long term soil biological activity, ensure effective peak management, recycle wastes to return nutrients to the land, provide attentive care for farm animals and handle the agricultural products without the use of extraneous synthetic additives or processing in accordance with largely acceptable standard and applicable standards of destination country/ countries. Organic farming has several advantages over the conventional one apart, from the protection of both the environment and human health. Improved soil fertility, better water quality, prevention of soil erosion, generation of rural employment, etc. are some of them.

troduction

Indian economy depends on agriculture and the agriculture sector in India contributes about17 percent of country’s GDP and provides employment to approximately two third of the population (United Nation Development Programme Fact sheet 2011). India is the second most populous country in the world. With the increasing population, the cultivable land resource is shrinking day by day. To meet the food, fibre, fuel, fodder and other needs of the growing population, the productivity of agricultural land and soil health needs to be improved. Green Revolution ushered through use of modern agriculture technologies such as greater use of synthetic agrochemicals like fertilizers and pesticides, adoption of nutrient-responsive, high-yielding varieties of crops, greater exploitation of irrigation potentials, etc. undoubtedly has increased production and labour efficiency in the post-independence era and made our countries self-sufficient in food production.
