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. 

Historical Perspective

Organic Farming was initiated in about 10,000 years back when ancient farmers started cultivation depending on natural sources only. There is a brief mention of several organic inputs in our ancient literature like Rigveda, Ramayana, Mahabharata, Kautilya Arthashastra etc. In fact, organic agriculture has its roots in traditional agricultural practices that evolved in countless villages and farming communities over the millennium.

Organic Movement

The organic movement began in the 1930s and 1940s as a reaction to agriculture’s growing reliance on synthetic fertilizers. Artificial fertilizers had been created during the 18th century, initially with superphosphates and then ammonia derived fertilizers mass-produced using the Haber-Bosch process developed during World War I. These early fertilizers were cheap, powerful, and easy to transport in bulk. The 1940s has been referred to as the ‘pesticide era’. Sir Albert Howard is widely considered to be the father of organic farming. Rudolf Steiner, an Austrian philosopher, made important strides in the earliest organic theory with his biodynamic agriculture. More work was done by J.I. Rodale in the United States, Lady Eve Balfour in the United Kingdom, and many others across the world. As a percentage of total agricultural output, organic farming has remained tiny since its beginning. As environmental awareness and concern increased, the originally supply-driven movement became demand driven. Standardized certification brought premium prices, and in some cases government subsidies attracted many farmers converting into organic farming. In the developing world, many farmers started organic farming according to traditional methods but are not certified. In other cases, farmers in the developing world have converted out of necessity. As a proportion of total global agricultural output, organic output remains small, but it has been growing rapidly in many countries, notably in Europe.

Organic farming primarily aimed at cultivating the land and raising crops in such a way so as to keep the soil alive and in good health by use of organic wastes and beneficial microbes. Organic farming is performed with an intension for maintaining diversity of crops, keeping soil healthy for future years, producing high quality products and recycling nutrients. Unlike modern agriculture, organic farming is not depended on synthetic chemicals. Instead, it depends on natural products to boost soil fertility through microbial activity. Organic farming uses a multiple cropping system, which benefits from growing several crops. This crop diversity supports a range of plants, insects, soil micro-organisms and animals that add to a healthy farming system. Organic farmings are of different types such as bio-farming, nature farming, eco-farming and biodynamic farming. Organic agriculture is developed with concented efforts by various people to create the symbiotic relationship between the nature and man. In the present day, organic agriculture has shown potentiality in commercial, social and environmental sector.

Organic farming is a production management system, which promotes agro-ecosystem and agrobiodiversity. The objective of organic farming is to generate all the required plant nutrients inside the farm and adopt crop protection using local resources. Organic farming emphasizes on the use of farm yard manure, crop residues, composts, vermi-compost and bio-fertilizers to enrich soil fertility and use of bio-control measures to manage insect and diseases. In particular, organic agriculture is intended to produce high quality, nutritious food which helps in preventive health care. Organic farming increases biodiversity at every level i.e. from micro-organism to mammals. It strengthens biodiversity by using bio-pesticides and inorganic fertilizers.

Globally, organic oilseeds constitute an important element in organic production. Their products are important feedstuffs (oilcake) and also relevant for human consumption (soya products, oils), and demand for these is continually growing. Almost half of the global organic oilseed area is occupied by soybeans, and another almost 20% is for sunflower seeds and sesame. Rape and turnip rape constitute about 6% of the organic oilseed area. Oilseeds are of pivotal significance in the Indian agricultural economy supporting income of millions of farmers practicing mainly rainfed cultivation. Nine annual oilseed crops are cultivated in India that includes groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower that are edible and non-edible oilseed crops include castor and linseed. Organic agriculture is one among the broad spectrum of production methods that are supportive of the environment. The principal method of organic farming includes crop rotation, green manures and composts, biological pest control and reduced tillage. The performance of annual edible oilseed crops and development of package in relation to organic management for sustainable agriculture are discussed in this chapter.

1. Introduction

In India, both annual and perennial edible oilseed crops are cultivated. Annual edible oilseed crops include groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower. India, the 4th largest vegetable oil economy in the world, stands first in the production of castor, sesame, safflower, and niger oils, whereas second in groundnut, third in rapeseed mustard, fourth in linseed and fifth in soybean oil. About 14 million farmers are engaged in oilseeds production and another million in their processing. Whereas, the perennial edible oil seed crops include oil palm and coconut. Edible oils are also produced domestically from secondary sources such as rice bran, cotton seed, corn, and other tree-borne oilseeds (TBOs), besides some minor oil producing species of forest origin.

Introduction

The goals and ideas of organic farming and regenerative agriculture are quite similar. Organic farming is a method of cultivating crops that prioritizes ecological sustainability by eschewing the use of artificial chemicals and genetically modified organisms in favor of more traditional practices. Producing residue- free food while also improving soil health, biodiversity, and ecological balance is the primary goal of this method. To restore and improve the health of the soil, ecosystems, and communities involved in agricultural systems, regenerative agriculture goes above and beyond organic farming. The ultimate goal is the development of resilient and sustainable agricultural systems that can deal with the effects of climate change.

Regenerative agriculture and organic farming share a common set of values, including an emphasis on the importance of good soils to successful and sustainable farming. Crop rotation, cover crops, and composting are some of the methods advocated by these people to improve soil fertility, structure, and biological activity. Preservation and promotion of a wide variety of plant and animal life on and around farms is an aim of both organic and regenerative farming practices. Pest and disease management, pollination, and ecosystem stability are all bolstered by biodiversity. Both methods encourage using less or no man- made chemicals, such as those found in pesticides, herbicides, and fertilizers. Organic matter, compost, and biological pest management are just some of the natural inputs that these farmers rely on. Water, energy, and material resource conservation are fundamental to both organic farming and regenerative agriculture. To lessen agriculture’s impact on the environment, they advocate for methods including water management, efficient irrigation systems, and the use of renewable energy. Strong relationships and collaborations between farmers, customers, and local communities are prioritized by these methods. All along the agricultural supply chain, they are committed to fair trade, social equity, and transparency. Farmers may grow healthy, resilient, and sustainable farming systems by applying the holistic concepts of regenerative agriculture to conventional organic farming practices. In addition to strengthening the bond between agriculture and its natural surroundings, these methods also improve soil quality, lessen negative effects on the environment, increase biodiversity, and result in more nutritionally dense food.

During the last decade organic agriculture has emerged as a dynamic alternate farming system. This has been necessitated as a consequence of resource degradation because of to achieving high yields in various crops to meet the increasing demand of food by the burgeoning population. These have resulted in change in soil structure, imbalance in soil micro-organisms and organic matter, resistance among various weeds to weedicides, increased salinity, sodicity and have affected the water holding capacity of the soil and brought in health and environmental problems. Organic farming is a specified form of diversified agriculture that not only aims to produce nutritious food of high quality but also lead to the generation of more income and employment opportunities for rural population. In true sense, organic farming is a production system which avoids or largely excludes the use of synthetic fertilizers, growth regulators, livestock feed additives and pesticides. Moreover, it relies on agronomic management practices like crop rotation, crop residues, animal manures, legumes, green manures, off-farming organic wastes and aspect of biological pest control to maintain soil productivity.

The inability of Indian agriculture to meet the demand for food in the country during the two and half decades immediately after independence had been a matter of concern at those times. The system of our agriculture based on the traditional knowledge and practices handed down from generation to generation could not produce enough to feed the increasing population. The ignominy of our dependence for food on the western developed nations and the politics of food aid practiced by them added to our determination to be self-sufficient in food production by modernizing agriculture. The green revolution fulfilled our aspirations by changing India from a food importing to a food exporting nation. However, the achievement was at the expense of ecology and environment and to the detriment of the well-being of the people.

1. INTRODUCTION

India is traditionally rich on agricultural knowledge. Presently modern farming is not sustainable in consonance with economics, ecology, equity, energy and socio–cultural dimensions. Indiscriminate use of chemical fertilizers, herbicides and pesticides to boost the yields have resulted in various environmental and health hazards along with socio–economic problems. The agricultural production has continued to increase, but the trend in productivity has started declining. The agricultural scientist’s and farming community whole heartedly aim at an alternative sustainable farming system which will be ecologically sound, economically viable and socially acceptable. The answer to the problem lies in refining our own traditional practices based on natural and organic farming methods offering several safe, feasible and cost effective solutions.

The term ‘Organic farming’, a system of farming is one which avoids synthetic fertilizers but rely upon crop rotation also using crop residues, animal manures, legumes, green manures, biofertilizers, organic wastes etc., to maintain the soil fertility and increase productivity. This system enables the nutrients leaching from perennial wood and vegetation and help to maintain organic matter and protect the soil from surface erosion. The world wide awareness for adopting organic farming has paved way for streamlining the production technology and certification by adopting the specified crop production practices. Organic farming practices in agriculture and animal husbandry are native to East Asian countries, like India and China. In China a strong national movement for animal waste recycling is in vogue, minimizing the use of inorganic fertilizers (Xu, 2000), while in our country specific crop production practices are developed in isolation and adopted locally.

The trend of use of chemicals and industrial inputs in intensive farming is increasing which resulted in soil health deterioration and increased environmental pollution which causes a great concern all over the world. Therefore an emphasis on the need to use the organics and other byproducts of agriculture and industry is emerging. Fortunately, the country is already rich with left over crop residues (185 million tonnes) but its use presently is limited. Apart from crop residues, there is an enormous quantity of cattle wastes out of which sixty per cent of the used for fuel purpose in rural areas.

Green revolution 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. has boosted the production output in most cases. However, continuous use of these high energy inputs indiscriminately now leads to decline in production and productivity of various crops as well as deterioration of soil health and environments.

1. Introduction to Organic Farming

Definition and Principles of Organic Farming

Organic farming is not merely a set of agricultural practices; it is a profound philosophy that seeks to redefine humanity’s relationship with the land. At its core, organic farming is an intricate dance with nature, a commitment to fostering biodiversity, ecological balance, and sustainability.

Defining Organic Farming

Organic farming is a departure from conventional agricultural methods that rely heavily on synthetic inputs. It is an agricultural system that embraces natural and traditional approaches to cultivation.
