Improvement of the tillage system in the conditions of irrigation of the Tersko-Sulak substructure

Abstract

Relevance. The main reason for the decrease in crop yields during soil compaction is the deterioration of conditions for the formation of a powerful root system and its active activity, therefore, the physical properties of soils are important in increasing the effective fertility of soils and obtaining high yields of cultivated crops. Proper regulation of the agrophysical properties of soils is the main task of tillage. The aim of the study is to study the influence of the tillage system on the phases of development of winter wheat in the irrigated plain zone on the agrophysical indicators of meadow-chestnut soil and grain productivity.Methods. The field experiment was carried out in the irrigated zone of the Tersko-Sulak substructure on meadow-chestnut soil. The scheme of the experiment includes a system of tillage (irrigation half-steam and half-steam) and fertilizers (at 3 levels of mineral nutrition for winter wheat).Results. The use of irrigation half-steam and half-steam treatment systems in irrigated agriculture of the Tersko-Sulak substructure has a beneficial effect on the agrophysical properties of the soil, which are able to resist the erosion of arable land from water erosion, contributes to the productivity of winter wheat. Characterizing the evaluation of the study on tillage systems for winter wheat cultivation, the predominant indicators for the semi-steam treatment system are associated with a better content of productive moisture, agrophysical properties of soils and the introduction of mineral fertilizers, which affected the increase in yield and grain structure. Thus, an adaptive system of meadow-chestnut soil treatment under irrigation conditions has been determined.
