Abstract: The present investigation entitled "Effect of different sowing dates and irrigation methods on quality and quantity of hybrid cotton {Gossypium sp. L.) seed production" was carried out at the experimental field of Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar during the summer season of 2000. The experiment was laid out in factorial randomised block design with four replications. Eight treatment combinations were formulated involving two irrigation methods viz. drip and surface irrigation and four sowing dates viz. 16th March, 1st April, 15th April and 1st May. In surface method, irrigations were scheduled at 50 mm CPE. In case of drip irrigation alternate day water application was made. It was observed that drip irrigation saved 54.51, 51.55, 52.24 and 46.66 per cent of water over conventional surface method of irrigation for the crops sown on 16th March, 1st April, 15th April and 1st May, respectively. Maturity of the crop was delayed due to drip irrigation as compared to surface irrigation. Number of flowers available for emasculation and pollination, percentage of boll setting, number of bolls harvested per plant, average boll weight and average seed weight per boll was higher in drip irrigation treatments as compared to surface irrigation treatments. Seed cotton yield and seed yield was higher in drip irrigation treatments as compared to surface irrigation treatments. Germination percentage, vigour index and seedling dry matter was higher in drip irrigation treatments as compared to surface irrigation treatments but the differences were non-significant. The incidence of pests and diseases was found to be less in drip irrigation treatments as compared to surface irrigation treatments. It was found that as the sowing was delayed from 16th March to 1st May, the maturity of the crop was earlier. The number of flowers, available for emasculation and pollination, percentage of boll setting, number of bolls harvested per plant, average boll weight and average seed weight per boll were decreased as the sowing was delayed. Seed cotton yield, seed yield were decreased as the sowing was delayed. Germination percentage, vigour index and seedling dry matter of seeds obtained from later sowing dates were found to be less. The incidence of pests and diseases was increased as the sowing was delayed.
