Abstract:

To study the effect of different rates and times of N application on productivity and fiber quality of Bt cotton, a field experiment was conducted during the rainy (June-November) seasons of 2014 at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi, India. Nine treatments were formed by combinations of the two factors i.e. four N rates (100, 125, 150, and 175 kg ha-1) and two timings of N application (i.e. with 30 kg N ha-1 as basal and without basal) with a control. The experiment was conducted in a factorial randomised complete block design with four replications. Results revealed that seed cotton yield, cotton seed and lint yield was positively affected by N- application. The highest seed cotton yield (2.65 t ha-1), cotton seed (1.73 t ha-1) and lint yield (0.93 t ha-1) were recorded with 175 kg N ha-1. The different quality parameters (ginning %, micronaire (mg/inch), fiber elongation %, 50% span length, fiber strength (g/tex) and lint index) were also affected by N application. The highest values for ginning % (34.9), fiber elongation % (6.3), 50% span length (14.7 mm) and lint index (5.1) recorded with 175 kg N ha-1 while for micronaire (3.9 mg/inch) was recorded with 150 kg N ha-1. The different quality parameters under study, recorded higher values with basal application of N compared with without basal application.
