Biological agents in the Khabarovsk Territory crop production

Abstract

In the research course for the period from 2007 to 2020, the high biological agents’ biological efficiency in the growing black currant berry culture technologies, as well as on vegetable crops, such as tomato, cucumber, asparagus beans, eggplant, was experimentally established. The biological agents stimulating effect on the leaf surface area, the plant development phases passage rate, as well as the crop yield is noted.
