The field experiment was carried out at Cotton Research Station, Sardarkrushinagar Agricultural University, Talod (Gujarat) for three consecutive years (2014-15, 2015-16 and 2016-17) to find the Nutrient requirements of newly developed Bt cotton hybrid GTHH 49 BGII. The experiment was laid out in Factorial Randomized Block Design with three replications. Three nitrogen levels viz., N1: 160 kg N/ha, N2: 240 kg N/ha and N3:320 kg N/ha, two Phosphorus levels i.e., P1: 0 kg P2O5/ha & P2: 80 kg P2O5/ha and three potassium levels i.e., K1: 0 kg K2O/ha, K2: 60 kg K2O/ha and 120 kg K2O/ha. The results indicated that significantly higher seed cotton yield (3029 kg/ha), higher gross returns (Rs. 151450 /ha), net returns (Rs. 85628 /ha) and B:C ratio (2.30) was recorded in application of 320 kg N/ha over other nitrogen levels. Application of 120 kg K2O/ha produce significantly higher seed cotton yield (4079 kg), higher gross returns (Rs. 166750/ha), net returns (Rs. 100238 /ha) and B:C ratio (2.50) over other potassium levels. It was also observed that application of phosphorus was found not advantageous to the cotton crop. There is no interaction effect was recorded with nitrogen and potassium on cotton. Application of 320 kg N/ha along with potassium 120 kg/ha in Bt cotton hybrid GTHH-49 BGII gave significantly higher seed cotton yield and maximum net returns.
