Abstract: An experiment during kharif-rabi season of 2016-17 to 2018-19. The experiment was laid out in a split plot design with three replication. The results revealed that significantly maximum seed cotton yield and stalk yield were recorded when sowing of crop at narrow row spacing of S₁ (30-60-30 cm x 30 cm) over wider row spacing during individual years and on pooled data basis, which was found statistically at par with S₂ (i.e. 30-90-30 cm x 30 cm) during individual years as well as in pooled results. Significantly maximum plant population and plant height were noted when crop was sown at closer paired row spacing of S₁ (30-60-30 cm x 30 cm) during individual years and in pooled results, accordingly. Bt cotton sown at wider spacing of 120cm x 45cm (S₄) recorded maximum sympodial branches, Least number of monopodial branches per plant, maximum number of bolls and boll weight during individual years and on pooled data basis Fertilizing the crop with 125% RDN through fertigation (N₃) in eight equal splits at 15 days interval produced significantly superior in all growth, yield attributes and yield parameters.
