EFFECTIVENESS OF DIFFERENT SPRING DURUM WHEAT PRECURSORS UNDER THE CONDITIONS OF COMMON CHERNOZEM OF NORTHERN KAZAKHSTAN

Abstract

The relevance of the research lies in the fact that with the annually growing areas of sowing of spring durum wheat in the North Kazakhstan region, crops are mainly located on fallow predecessors, which does not affect the increase in yield, which rarely reaches 1.5 - 1.8 t/ha. Scientific studies involved a comparative study of various predecessors - peas, corn for green fodder, flax, spring wheat, in comparison with pure fallow. The research methodology involved field laying experiments in a hospital, as well as a laboratory assessment of the productivity of agricultural crops. According to the results of the study, along with pure fallow, leguminous crops, row crops (corn), cereals can act as a precursor of spring durum wheat. The results obtained are substantiated by an increase in the yield of durum wheat, a productive consumption of moisture during the growing season, as well as a supply of nutrients. The practical value of the conducted research lies in obtaining reliable data on the optimal technology for long-term cultivation of spring durum wheat in crop rotations, or permanent crops, with their potential use by farms to increase production levels
