Southern Action on Genetic Engineering has alleged that Bt cotton has done little to increase yield.
Net increase in yield, in fact, is dwindling in the last few years. “It has gone up by just 4 kg to 474 kg a hectare in 2009-10 from 470 kg in 2004-05,” Mr P.V. Satheesh, Convener of SAGE, said.
Sage is an umbrella organisation of NGOs and intellectuals who oppose genetic engineering in agriculture.
