Bt cotton was introduced in India in 2002 and has found favour with the government as well as Cotton Association of India, which attributed increased output this year to higher productivity of Bt cotton. [...] However, Krishan Bir Choudhary, president of Bharatiya Krishak Samaj and former director, National Agricultural Cooperative Marketing Federation (Nafed), junked the claim. ”The rainfall was better. Wherever crops receive enough water, production has been good, and not just for cotton. The Bt gene is meant to prevent bollworm pest and does not boost productivity at all,” said Choudhary.
