Abstract

Spring barley is a multipurpose crop. High-quality and valuable grain is grain with a high protein content, which is formed at high temperatures in the phase of grain filling. But droughty conditions are unfavorable for the entire growing season of plants. Therefore, the cultivation of spring barley in an arid climate requires a competent approach and is based on a rational combination of agrotechnical methods, among which a special place is given to the main tillage. The purpose of the research is to establish the effect of various methods of soil cultivation on soil moisture and density, as well as on the yield of barley. We studied 4 options for soil cultivation: deep flat-cut, deep layer-by-layer non-moldboard, deep moldboard plowing and direct sowing without tillage. According to the results of the research, the highest soil moisture was established with direct sowing. A decrease in soil moisture was revealed for layer-by-layer tillage by 12.46%, for flat-cut till-age by 13.83%, for moldboard tillage by 15.84%. Studies of soil density by the phases of development of spring barley for each of the methods of soil cultivation have established an increase in density with depth. The highest yield of spring barley was obtained with direct sowing. At the same time, it exceeded the yield with the dump method of tillage by 4.37%, with the layer-by-layer method by 14.48% and with the flat-cut method of tillage by 17.26%. Thus, in arid conditions, direct sowing provided the best results in soil moisture and yield in the cultivation of spring barley

Summary

Introduction

Soil aggregates interconnected layer by layer acquire a soil skeleton with a chaotic distribution in the inter-aggregate space with macro- and micropores [6] Under such conditions, the process of thermal diffusion contributes to the long-term preservation of soil moisture. Fluctuations in seasonal, day and night temperatures of air and soil determine the magnitude and direction of movement of soil moisture inside the soil layer in the form of soil vapor [7]. In this connection, tillage must ensure the movement of moisture within the soil layer and at the same time prevent evapotranspiration. For the formation of a favorable soil structure [8, 9], various methods of its cultivation are used: dump, dump-free, layer-by-layer, surface or cultivation of agricultural crops without soil cultivation [10]
