DEVELOPMENT OF A SCIENTIFICALLY BASED IRRIGATION REGIME FOR COTTON IN HYDROMODULAR REGIONS

Аннотация

At the time of year-to-year global climate change, and taking into account the water demand of cotton grown in the Kashkadarya region in order to prevent the decrease in productivity and quality of agricultural crops due to the lack of irrigation water compared to the crop demand, the method of seasonal irrigation using the data of the weather station. using CropWat 8.0. Based on the program, the coefficient values for the development stages of cotton were adopted based on the mechanical composition of the soil, the depth and mineralization of seepage waters. The results of scientific research carried out by scientists in cotton fields were analyzed in Kham. In addition, scientifically based irrigation methods of water-saving irrigation technology of cotton were developed according to generally accepted hydromodule regions for the conditions of Kashkadarya. According to the developed software, the seasonal irrigation standards of cotton in the hydromodule regions were 3500 m3/ha for each hectare of the ninth hydromodule region, and 6900 m3/ha for the first hydromodule region.
