ABSTRACT
A field experiment was undertaken in farmer's field at Jodalli village (Kalghatgi taluk) in 2012-13 and at Pale village (Hubballi taluk) in 2013-14 under protective irrigation to study the effect of graded levels of NPK fertilizers on yield and quality of Bt cotton. The results of the study revealed that, among the different treatment combinations, a significantly higher seed cotton yield (2283 kg ha-1) was recorded in treatment receiving 150:50:75 kg N:P2O5:K2O ha-1 (N3P1K2) during both the years of experimentation. However, the treatment N2P2K3 (125:50:100 kg N:P2O5:K2O ha-1) was on par with N3P1K2. The interaction effect of nitrogen, phosphorus and potassium failed to exert significant influence on fibre quality parameters except for ginning out turn.
Key words :
