A field experiment was carried out during the kharif season of 2015 at the research farm of Department of Genetics & Plant Breeding, CCS HAU, Hisar (Lat. 29° 10' N, Log. 75°46' E and 215.2 m msl) to study the effect of fertility and plant spacing on plant height, dry matter accumulation, LAI and yield of the Bt cotton. The experiment was laid out in split- split plot design with 3 varieties (RCH 602, RCH 650 and Bunty) in main plot, 3 plant geometries (67.5 × 75 cm, 67.5 × 60 cm and 67.5 × 45 cm) in sub plot and 3 fertilizer levels (Recommended Dose of NPK (RDF= N:P:K: 175:60:60 kg/ha), 125 per cent of Recommended Dose of NPK and 150 per cent of Recommended Dose of NPK) in sub-sub plot with 3 replications. RCH 602 attained maximum plant height, dry matter accumulation, LAI and yield (1248.7 kg ha-1) followed by RCH 650 and Bunty. Maximum plant height and LAI at 120 days after sowing were recorded in plant geometry 67.5 × 45 cm,whereas the plant geometry 67.5 × 75 cm have maximum dry matter accumulation and yield (1120.7 kg ha-1). Maximum plant height, dry matter accumulation and LAI (at 120 days after sowing) were found significantly higher in RDF 150 per cent, however the maximum yield was recorded with RDF 125 per cent (1094.3 kg ha-1).
