Effect of soil treatment and bacterial fertilizers on the productivity of yarn barley

Abstract

The article presents experimental data on the integrated influence of ways of the basic processing of soil and bacterial fertilizers Azotovit and Fosfatovit on agrophysical, water-physical soil indicators and productivity of barley. The use of planing treatments leads to compaction of the arable layer above the biological optimum and impaired soil aeration, therefore their application is possible without compromising the cultivation of spring barley. The influence of methods of primary tillage and application of mineral and bacterial fertilizers on barley water consumption and efficiency water production unit. Summarized long-term data on the productivity of spring barley on the learning options. The advantage of the double inclusion Azotovit and Fosfatovit in the background planing treatment at a depth of 0.20-0,22 m. the yield in this embodiment was 1.7 t/ha, which is higher than where were made only mineral fertilizers - 0,63 t/ha. A calculation of profits, the profitability of the technology of cultivation of spring barley and identified cost-effective version of the experience includes a two-fold introduction of bacterial fertilizers on the background of planing processing of soil to a depth of 0.20-0,22 m. the Margin amounted to 46.2%. On the basis of the conducted researches it is theoretically substantiated, experimentally confirmed and the findings and recommendations of the use of technology in the Volgograd region.
