Abstract

A field experiment was conducted during kharif 2015-16 and 2016-17 at College farm, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad in strip-plot design with three replications to study the effect of moisture conservation practices (flat bed sowing, ridge and furrow, broad bed and furrow (BBF) and poly mulch on BBF) and integrated nutrient management treatments (Farmer’s practice, 100% RDF of 150:60:60 NPK kg ha-1, 125% RDF, 100% RDF along with 25% N through FYM or press mud) and their interaction effect on growth, yield attributes and productivity of Bt cotton. Pooled data of two years indicated that poly mulch on BBF increased the growth, yield attributes and yield (2183 kg ha-1) followed by ridge and furrow method, BBF and flat bed methods. Among the INM practices, application of 100% RDF along with 25% RDN
through press mud improved the growth, yield attributes and yield (2103 kg ha-1). Application of 100% RDF along with press mud equivalent to 25% RDN was on par with 100% RDF + 25 % RDN through FYM (2042 kg ha-1) and was in turn on par with 125% RDF (1990 kg ha-1) followed by farmer’s practice (1785 kg ha-1) and 100% RDF (1676 kg ha-1). Interaction between soil moisture conservation practices and integrated nutrient management practices was found to be significant. Treatment combination involving poly mulch on broad bed and application of 100% RDF along with 25% RDN through pressmud (2370 kgha-1) recorded
significantly highest mean seed cotton yield and was comparable with poly mulch on broad bed with application of 100% RDF along with 25% RDN through FYM (2346 kgha-1) or 125% RDF.
