Investigation of the dependence of various backgrounds of modern fertilizers and Triticum aestivum (L.) yields in the Southern Federal District of Russia

Abstract

Despite the large areas occupied by the wheat, still an increase in its productivity is in need, especially in years with difficult climatic conditions. The task of raising the yield of winter wheat is not new and can be accomplished in a number of ways, with new crop types and current technologies based on the use of fertilizers being the most important. However, the influence of various fertilizers on the productivity of different varieties under certain conditions of crop growth in most cases remains open. Therefore, a study was conducted in the conditions of the dry-steppe zone of light chestnut soils of the Samara region on the predecessor –Hordeum sativum J.– on 16 varieties of two breeding centers. The field experience was laid at the experimental site of the Federal Research Center for Agroecology, Russian Federation during 2020-22. The studied varieties showed significant differences in productive stem and productivity. The background of nutrition, as well as the forms and doses of the studied complexes ammonium nitrate + biologics (Active ingredient amino acids) provided a significant increase in the gluten content in winter wheat grain compared to the natural background (without treatment). The presented results require further study, but already now we can talk about the positive effect of additional nutrition on increasing the productivity of Triticum aestivum L.
