| Popis: | The highest yield of the promising cotton variety Pakhtakor-1 was achieved by irrigating the cotton with placing black plastic film. Accordingly, the average yield for 3 years was 37.2 q/ha, which was more by 7.9 q/ha than the control variant, whereas it was higher by 2.7 q/ha than Bayaut-2 variety of cotton, in which the same irrigation method was applied. It was found that in Pakhtakor-1 variety, fiber yield was 38.1-39.9%, followed by fiber length 33.5-34.0 mm and weight of 1000 seeds was 115-120.1 grams. Cotton fiber yield, fiber length and weight of 1000 seeds in Pakhtakor-1 for the three years were higher by 0.2-1.0 %, 0.1-0.7 mm and 0.4-1.6 mm, correspondingly, than the standard An-Bayaut-2. The highest economic efficiency of cultivating standard An-Bayaut-2 and promising cotton varieties Pakhtakor-1 through various irrigation technologies was achieved in the form of irrigated with black plastic film, accounted for net profit of 1943902 sums/ha (45 % profitability rate) and 870,583 sums of additional income (17.2 % the profitability rate) than the control. |
