ABSTRACT

A field experiment was conducted during kharif seasons of 2006 and 2007 for two
years on vertisols. The experiment consisting of four spacings(120 x 60, 90 x 90, 90
x 60 and 90 x 45 cm) in main plots and ten nutrient combinations viz., no fertiliser ,
80 kg N / ha, 120 kg N / ha, 160 kg N/ ha, 75% RDF (90 - 45- 45 kg NPK/ ha), RDF
(120-60-60 kg NPK / ha),125% RDF (150-75-75 kg NPK / ha, 80 kg N- 40 kg K2O /ha,
120 kg N-60 kg K2O /ha and 160 kg N-80 kg K2O / ha in sub plots , was laid out in
split plot design with three replications. The results revealed that planting Bt cotton
at 90 cm x 45 cm with 150-75-75 kg NPK /ha gave higher kapas yield.
