A field experiment was conducted at Punjab Agricultural University, Ludhiana during kharif, 2004. The treatments comprised of four irrigation schedules (Irrigation application at 75, 95, 115 and 135 mm of cumulative pan evaporation) and four dates of irrigation termination (10, 20, 30 September and 10, October). The treatments were replicated four times in randomized block design. Ginning outturn was not affected due to schedule of irrigation upto the last irrigation. Highest oil content (19.34%) was observed under 135 mm CPE, which was significantly higher than 75 and 95 mm CPE but was at par with 115 mm CPE. None of the quality characters were significantly influenced by different irrigation schedules as well as date of termination of last irrigation. Maximum seed cotton yield was recorded at 95 mm (16.23 q/ha) followed by 75 mm (16.22 q/ha) CPE and these two irrigation regimes being at par with one another and they were significantly superior to 115 mm (13.98 q/ha) and 135 mm (12.66 q/ha) CPE. Termination of last irrigation on October, 10 produced highest seed cotton yield (15.64 q/ha) as compared to termination on September, 10 and 20 but at par with September, 30.
