Abstract

An experiment was conducted during kharif season of 2024 at Regional Agricultural Research Station, Acharya N G Ranga Agricultural University, Lam, Guntur. The experiment was laid out in FRBD with three replications. In growth characters, significantly higher plant height was recorded in plant spacing 105x60 cm over both the remaining spacings. Significantly higher number of sympodial branches/plant and values of sympodial length were recorded in plant spacing 105x60 cm over remaining spacings. Nitrogen level @ 125% STBN recorded significantly higher plant height, number of sympodial branches/plant and sympodial length than 75% and 100% STBN. Among yield attributing parameters, the spacing S3 produced statistically higher number of bolls per m2 and seed cotton yield over S1. Nitrogen level 125% STBN recorded significantly higher number of bolls per m2 than remaining nitrogen levels. Boll weight was not affected significantly by plant densities, nitrogen levels and their interaction (Spacing x Nitrogen). Interaction effect of (Spacing x Nitrogen) was also found non significant on seed cotton yield.
