Abstract

A field experiment was conducted during kharif, 2008 at Agricultural College Farm, Raichur to study the performance of Bt cotton genotypes to different plant densities under rainfed condition. The results revealed that among genotypes, Bunny Bt BG-II recorded significantly higher uptake of nutrients (105.5, 22.08 and 114.25 kg ha-1; N, P and K, respectively) and also exhibited superior quality parameters with higher net returns (Rs. 39,152 ha-1) and BC ratio (2.91). Among the spacings, net returns and uptake of nutrients was significantly higher with 60 x 30 cm followed by 75 x 30 cm. Quality parameters did not differ significantly between different spacings
