ABSTRACT
A field trial was conducted for three seasons from 2006-07 to 2008-09 with an objective to find out the response of hybrid Bt Bunny to three different nitrogen levels (120, 150 and 180 kg ha-1) and scheduling of nitrogen in five equal splits at 25 days interval viz., 15-40-65-90-115 days after sowing (DAS),20-45-70-95-100 DAS and 25-50-75-100-125 DAS under rainfed conditions at Scheduling of nitrogen from 20 or 25 days after sowing gave significantly higher seed cotton yield (3592 kg ha-1 and 3630 kg ha-1) than scheduling nitrogen from 15 DAS with seed cotton yield of 3138 kg ha-1. The other parameters like number of monopodia and sympodia per plant, boll number and boll weight were not influenced by nitrogen scheduling. Nitrogen application at different levels did not influence the seed cotton yield, number of monopodia and sympodia per plant , boll number and boll weight. However, the seed cotton yield ranged from 3300 kg ha-1 to 3600 kg ha-1 indicating the potentiality of the hybrid Bt Bunny. No significant interaction among the different variables for any treatment combination was observed. However, the net returns and BC ratio were highest for nitrogen at 180 kg ha-1 and scheduling from25 DAS.
