Complex agrotechnological measures to increase the yield and drought resistance of spring soft wheat varieties

Abstract

Background and Aim. Spring soft wheat is a major export crop in the country. Wheat yields are significantly impacted by global climate change, a phenomenon observed over the last decade. The absence of an adapted system of measures for wheat cultivation measures could threaten the food security of the whole region. Therefore, the primary objective of this study was to investigate the system of complex agro technological measures to mitigate the negative impact of drought on spring soft wheat yield formation.

Materials and Methods. The field experiment was conducted according to standard agronomic methodologies. Spring soft wheat varieties were studied, incorporating complex seed treatment and surface soil preparation. Throughout the study, actual wheat yield, yield stability index, tolerance, modeled yield value, stress tolerance index and plant susceptibility index were evaluated and analyzed.

Results. The field studies demonstrated that agro technological measures significantly influence the yield and drought tolerance of spring soft wheat varieties.

Conclusion. Based on the results, it is recommended to implement the following practices in the main grain growing regions of dry-steppe zone of Central and Northern Kazakhstan: wheat seed treatment with a complex preparation, crop fertilization during the tillering stage, soil rolling after sowing and harrowing during tillering stage.
