Abstract

This article notes the geographical location and soil-climatic conditions of Kashkadarya province in Uzbekistan, as well as the mechanical composition, agrochemical properties and dynamics of nutrients in the soil of field experiments conducted in the conditions of typical irrigated gray soils in Shakhrisabz district. In total, 36% of the irrigated soils of the Kashkadarya basin are typical gray soils, and the genetic layers of the soils of the studied area are medium sandy, with large dust particles predominating in the mechanical fraction and create nutritional regimens. In the driving layers of the studied soils, humus 1.094%, total nitrogen 0.080%, total phosphorus 0.168%, total potassium 1.07%, mobile nitrogen, phosphorus and exchangeable potassium belong to low and moderately supplied groups. It is also possible to fully demonstrate the potential of cotton by creating a scientifically based nutrient environment for the promising variety “Porlok-4”.

Highlights

The role of soil fertility and high-yielding varieties and modern technologies in improving the well-being of the population, including Uzbekistan, and its appeal to the world community is invaluable [1, 8, 9]
In recent years, soil fertility, including irrigated soils, has declined, making it impossible to obtain the expected yield. This is due to the fact that scientifically based fertilizer standards and ratios, i.e. ‘soilvariety-fertilizer’ ratio, which take into account the optimal nutrient environment for intensive crops, the level of nutrient availability of soils, soil-climatic conditions and other
According to the chemical analysis of the soil sample taken from the genetic layers of the field experimental soils, it was found that the genetic layers consisted mainly of medium sandy soils, the lower 120-217 cm layers of heavy sandy mechanical composition, and large dust particles predominated by mechanical fractions

Summary

Introduction

The role of soil fertility and high-yielding varieties and modern technologies in improving the well-being of the population, including Uzbekistan, and its appeal to the world community is invaluable [1, 8, 9]. Uzbekistan, but all over the world requires the rational use of land and water resources, their conservation, the provision of the population with environmentally safe food on a global scale. In recent years, soil fertility, including irrigated soils, has declined, making it impossible to obtain the expected yield. This is due to the fact that scientifically based fertilizer standards and ratios, i.e. Failure to follow the balance between these factors leads to a decrease in the expected yield or the effectiveness of agro-technical measures [1, 3]
