Improvement of cotton nutrition procedure and irrigation technologies

Abstract

This article presents the results of research-fertilization by laying a black polyethylene film between the rows of cottonand field experiments on irrigation technologies conducted in the conditions of typical gray soils of Tashkent region. In order to save water in the irrigation of cotton and other crops, mulching between rows with black polyethylene film and straw and the introduction of irrigation technology using flexible artificial pipes is highly effective. The plant thrives only when the soil moisture is moderate. This can be achieved by improving irrigation techniques and technologies. In field experiments, the timing and rate of cotton irrigation were determined by soil moisture. It was found that the seasonal water norm saved an average of 1,095 m3 or 27.3% of irrigation water per hectare in the variants irrigated between rows with black polyethylene film compared to the options irrigated by conventional irrigation.
