Notwithstanding a rise in acreage, cotton yield in India has been declining for the past three years mainly on account of erratic weather conditions and increased usage of spurious Bacillus Thuringiensis seeds for the cotton cultivation in some parts of the country. According to data available with the Cotton Advisory Board, the cotton yield in India has dropped from 554 kg per hectare in 2007-08 to 524 kg, 498 kg, 475 kg in 2008-09, 2009-10 and 2010-11 respectively.
