The influence of different nutrition schemes on the yield of spring durum wheat with different methods of basic tillage

Abstract

The influence of various nutrition schemes on the yield of spring durum wheat with various methods of basic tillage has been studied. In the course of the study, two methods of basic tillage were considered: plowing with a PLN-5-35 plow to a depth of 22-25 cm, minimum soil tillage with a BDM 7 ? 3 disc harrow to a depth of 10-12 cm. It has been analyzed the effect of ammophos at a dose of 60 kg/ha, Strada N - 3 l/ha, Microel - 0.2 l/ha, Azofit - 2 l/ha. It is concluded that the yield of durum spring wheat varied significantly over the years of research. In addition, it varied depending on the method of basic tillage, as well as on the application of mineral and bacterial fertilizers. The largest yield increase compared to the control was in the variant with the application of ammophos and Strada N both during plowing and minimum tillage. After plowing, the yield was 1.43 t/ha, which is 0.28 t/ha higher than in the same variant during minimum tillage.
