The influence of individual elements of agricultural technology on the productivity of durum wheat in the southern forest-steppe of the Omsk region

Abstract

Relevance. For the manufacture of high-quality pasta, durum wheat grain is used. Improving the productivity of hard spring wheat is an urgent task. The formation of a powerful root system is the key to the full supply of nutrients and plastic substances to the plant. Increased productivity, the number of spikebearing shoots. Plants become more resistant to adverse environmental factors, which is important for spring durum wheat, which is more demanding than spring soft wheat. The timing of sowing and especially the application of mineral fertilizers are a significant factor affecting not only the formation of individual elements of the crop structure, which subsequently form the productivity of plants, but also the formation of the root system. To do this, it is necessary to choose the optimal sowing time, at which the critical phases of plant development fall under the most favorable agrometeorological conditions and the formation of the most powerful root system.

Results. The conducted studies allow us to recommend the most optimal terms of sowing and the use of fertilizers to ensure the efficiency of growing durum spring wheat. In dry conditions, when sowing crops without applying fertilizers, sowing in the second ten days of May is most effective. If it is possible to apply nitrogen fertilizers and nitrogen-phosphorus fertilizers, it is better to sow durum spring wheat in the second and third decades of May.
