Organic farming is based on principles of health, ecology, fairness and care. It prohibits synthetic pesticides, fertilizers, GMOs, antibiotics and growth hormones. India's National Programme for Organic Production established standards and certification systems for the organic sector. Organic agriculture in India has grown from 42,000 hectares in 2003-2004 to 1.78 million hectares in 2017-2018. Standards address crop plans, conversion periods, nutrient management, and pest and disease control primarily using on-farm resources. The government promotes organic farming through various schemes.
