Abstract:

A field experiment was conducted during 2015-16 and 2016-17 at Hyderabad to assess the performance of two cotton hybrids of which Bt (MRC 7201 BGII) and non-Bt cotton (WGCV-48) in response to plant densities (P1: 18,518 plants ha-1, P2: 55,555 plants ha-1 and P3: 1,48,148 plants ha-1) and nitrogen fertilization (120, 150 and 180 kg ha-1). Among the cultivars during 2015 and 2016, MRC 7201 BG II cultivar recorded significantly more number of bolls plant-1 (28, 26), boll weight (5.12, 4.60 g), kapas yield (3497, 2866 kg ha-1), stalk yield (8492, 8193 kg ha-1) and harvest index (32.7, 29.3 %) in comparison to WGCV-48 cultivar, respectively. Among the plant densities, during 2015 and 2016 eventhough the plant density of P1: 18,518 plants ha-1 showed more number of bolls plant-1 (42, 40), boll weight (5.16, 5.0 g) and harvest index (43.3, 41.2 %) but the plant density of P2: 55,555 plants ha-1 significantly more kapas yield (3319, 2726 kg ha-1). However, remaining two plant densities P1: 18,518 plants ha-1 and P3: 1,48,148 plants ha-1 were showed comparable yields. While the nitrogen levels did not influence the no. of bolls plant-1, boll weight, ginning per cent, seed cotton yield, stalk yield and harvest index.
