Integrated nutrient mangement in rainfed hybrid cotton

Abstract

A field experiment was conducted at Regional Research Station, Bhawanipatna, Kalahandi, Orissa in the Kharif seasons of 1997 and 1998. The treatment N, P and K @ 100, 50 and 50 kg har along with Azatobacter and Phosphorus Solublizing Micro-organisma @ 5 kg ha' each, ZnSO, 25 kg ha' and FYM @10 t ha produced the highest seed cotton yield of 2728 kg ha' and that was on par (2695 kg ha') with the above treatment minus ZnSO, 25 kg ha¹. The crop height, bolls / plant and the boll weight recorded for both the above treatments were also on par with each other for both the years. However, the net return per rupee invested was the highest (Rs. 2.43) for the treatment N, P and K @ 100, 50 and 50 kg ha along with Azatobacter and Phosphorus Soublilizing Micro-organisms @ 5 kg ha-1 each and FYM @10 1 hat followed by Rs. 2.26 for the treatment N. P and K @ 100, 50 and 50 kg ha-1 along with. Azatobacter and Phosphorus Solubilizing Micro-organisms @ 5 kg/ha-1 each, ZnSO, 25 kg ha-1 and FYM @10 t ha-1.
