Abstract
The Krasnodar Territory is the main producer of raw rice - more than 90%, of all grown in Russia. The acreage of rice in farms of all categories of the Krasnodar Territory, as of 2014, is 130.8 thousand hectares, with a gross yield of 822.7 thousand tons with a yield of 62.9 c / ha. By 2020, in line with the strategy for the development of agriculture, it is planned to get more than 900 thousand tons of gross yield of rice and expand acreage to 150 thousand hectares. For the purpose of implementation the program, it is necessary to create new technologies and a highly effective complex of agrochemical measures for cultivating this culture. The submerged rice field is an integral environment for rice cultivation. The conditions for periodic flooding of soil under rice and its subsequent drying determine the nature of the soilforming process. The cultivation of rice by intensive technology leads to a depletion of the soil by mobile forms of the basic elements of mineral nutrition, the total reserves of organic matter and humus decrease in it, so the purpose of the research was to determine the biological efficiency of seed and plant treatment (topdressing at the seedling and tillering stage) by microbiological fertilizer Biovel-Rost.
