Since chemical dependent farming has started giving negative response. Organic farming, Ecological Farming. Natural Farming. Rishi Krishi, Biodynemic Farming and Agnihotra Farming have gained momentum globely which has spread over about 23 mh area. In India around 2.25 lac hectares area is alread covered under organic cultivation which includes cotton, coffee, tea basmati rice, medicinal and aromatic rops. A number of possibl attentive farming systems are summarized as under.
Organic Farming
As per USDA, 1980 report, organic farming can be defined as "Production system which avoids or largely excludes the use of synthetically compounded fertilizers, pesticides, growth regulators and livestock feed additives". This system rely upon crop rotation, crop residues, animal manures, legumes, green manures off-farm organic wastes, mechanical cultivation, mineral bearing rocks and aspects of biological pest control to maintain soll productivity and tilth to supply plant nutrients and to control insects weeds and other pests.
Natural Farming
It was developed in Japan in 1930 by Mokichi Okada whe later formed the Mokichi Okada Association (MOA). Natural Farming parallels organic farming in many ways but include special emphasis on soil health through composts rather than organic fertilizers, Kyusei Natural Farming, a branch group emphasizes use of microbial preparation in addition to traditional natural farming.
Ecological Farming
It is labour intensive system which is based on techniques of crop cultivation, which involves all attention to promote renewable source of energy (drought animal power), electrical energy from garbage disposal and biogas from organic wastes. It also involves water use efficiency through conjunctive use of rain, tank. underground well and river water. Practices such as those continue to improve crop productivity, i.e., genetic and agronomic i.e., hybrid vigour, gene pyramiding, multiple cropping. Integrated plant Nutrient management (IPNM) and Integrated Pest Management (IPM) are the essential components of ecological farming.
Rishi Krishi
This system is based on Mr. Deshpandey of Maharastra who is promoting it for 10 years. About 500 farmers in the state are now following the system for crop production. In this system the following aids are used to maintain soil fertility and crop yield.
Angara : Bhomi Sanskar is being performed to make the soil fertile, wherein 15 kg rhizosphere soil of banyan tree (Ficus bengalensis) Vat vriksh is broadcasted on acre of land. It has lot of earthworms and other beneficial microbes which improves the soil fertility.
Amrit Pani : Amrit Pani is prepared by mixing 20 kg cow dung, 1/2 kg honey, 1/4 kg ghee. All ingredients are mixed and kept over night. This is being used to treat the seeds and spraying over the standing crops.
Punch Gavya : It is basically consist of five products from cow i.e., dung (5 kg) urine (5 litre), milk (3 litre), curd (3 litre) and ghee (1 kg), suitably mixed along with sugar, cane juice, tender coconut water, ripe banana and toddy. It is incubated for 15 days and stirred daily. Mixture is diluted in 1:10 ratio with water, filtered, mixed and sprayed on the crop. This mixture is wonderful tonic to promote vegetative and reproductive growth of plants. A group of farmers in Tamil Nadu are practising this for cultivation of field and horticultural crops.
Bio-Dynamic Farming : Pfeffer (1984) defined biodynamic farming as working with energy which create and maintain life. It involves certain principles and practices for healthy soil. healthy plant and healthful food for human beings and feed for animals. In this system energies from cosmos, earth, cow and plant are systematically and synergistically harnessed.
