V Chandrasekhar Reddy, a farmer in Andhra Pradesh’s Kadapa district, has been reaping rich dividends since moving away from conventional farming. For the past four years, he has been using traditional seeds on his 11-acre farm. He has replaced chemical fertilisers and pesticides with those made from waste generated by cattle and other locally available material.

Called zero-budget natural farming, or ZBNF, it has reduced Reddy’s reliance on the market and, thereby, his cultivation costs. It has significantly improved crop quality as well.
