A field experiment comprised of three Bt hybrids (Leo cott, Paras Brahma and Jai Bt) with two plant geometries (90×45 cm and 90×60 cm ) and three levels of NPK (100% RDF,125% RDF and 150% RDF) was conducted during Kharif 2012 and 2013 at ARS, Banswara in Split Plot Design with four replications. The Bt hybrid of Leo cott gave higher seed cotton yield (2242 kg ha-1) as compared to Jai Bt and Paras Brahma (1809 and 1755 kg ha-1), respectively. The closer spacing 90×45 cm was recorded significantly higher seed cotton yield (2240 kg ha-1) over 90×60 cm (1752 kg ha-1). Increasing levels of fertilizer from 100% RDF to 150% RDF of NPK ha-1 significantly increase seed cotton. Application of 125% RDF gave significantly higher seed cotton yield (2249 kg ha-1) over 100% RDF (1815 kg ha-1), but it was found at par with application of 150% RDF (2304 kg ha-1) in the pooled analysis.Keywords
