Pазработка микробиологического способа повышения продуктивности сои в условиях почвенной засухи

Abstract

The new bacterial preparation “Rizosideps”, created on the basis of strain Pseudomonas aureofaciens CNMN PsB-03, revealed a high efficiency during tests in northern and central areas of Moldova (Soldanesti, Anenii Noi) on soybean plants Aura and Zenit. “Rizosideps” provided an increase of a crop by 240-340 kg per hectare (16-18 %) in comparison with control plants whichwere not processed by the preparation. The preparation “Rizosideps” influenced all the elements of soybean efficiency: increased number of pods by 31 %, their weight by 20 %, and average weight of beans from one plant by 19 %. The weight of 1000 seeds (beans) authentically grew by 7 % in comparison with the control, and was equaled by 176, 7 g. The quality of a bean crop of Zenit was higher using the “Rizosideps” preparation: the contents of protein achieved 36,2 % (increase in 17 % to the control), contents of oil- 17,7 %. Besides, the “Rizosideps” preparation increased by 12 % the content of copper trace in soybean leaves
