Effectiveness of various elements of grain cultivation technology

Abstract

The article presents the results of a long-term stationary three-factor experiment on sod-podzolic loamy soil to identify the effectiveness of various methods of basic and pre-sowing treatment of soil, the use of biological preparations in the technology of cultivating grain crops in six-field crop rotation. It was established that the most profitable elements of the technology in energy and economic terms will be: surface-cut treatment with KPS-4 cultivator and introduction of Azotovit and Phosphatovit biologics into the tillering stage of oat in a vetch-oat mixture for green feed; surface-cut treatment with KBM-4,2 cultivator or with pre-sowing treatment with a APPN-2,1 combined aggregate and introduction of Azotovite and Phosphatovite biological preparations into the soil before sowing winter rye for grain; ploughing with pre-sowing treatment with APPN-2,1 combined aggregate for spring wheat; surface-cut treatment with pre-sowing treatment with APPN-2,1 combined aggregate and introduction of biologic preparation based on strain Streptomyces hygroscopicus A4 at tillering stage of oat in pea-oat mixture for grain-hay; ploughing with KPS-4 cultivator and introduction of Pseudobacterin-2 biopreparation at barley tillering stage; ploughing with pre-sowing treatment with APPN-2,1 combined aggregate and introduction of biologic preparation based on strain Streptomyces hygroscopicus A4 at oat tillering stage.
