EVALUATION OF COTTON RELEASED/CANDIDATE VARIETIES UNDER DIFFERENT SOWING DATES AT TANDOJAM CONDITIONS
Abstract
A field study was conducted to evaluate the cotton released/candidate varieties under different sowing dates for the qualitative and quantitative characters at Nuclear Institute of Agriculture (NIA) Tando jam. Three sowing dates viz., 15th April, 15th May and 15th June and three varieties and one candidate variety were tested respectively. The result revealed that the highest mean (2983 kg ha-1) seed cotton yield has got sowing date two 15th May where as lowest mean (1996 kgs/ha) seed cotton yield in sowing date 15th June. The mean values of all varieties showed more seed index (8.34g) and highest (90%) germination percentage in sowing date 15th April and 15th May. The highest GOT% (35.42) and germination percent (89%) were recorded in 15th May sown crop. It was found that the delaying sowing date significantly decreased yield and yield contributing parameters.
