We have studied the effect of presowing enrichment with copper on the seed yield of rice. We have found optimum concentration of water solution of copper, which provides higher yields of seeds and evaluated the impact of the enrichment with copper on the growth processes in the plants of rice. The studies were conducted in elite seed-growing enterprise "Krasnoe" of All-Russian Research Institute of rice. It was found that for rice-growing farms of the Kuban region with the aim of increasing the quantity and quality of grain yield it is necessary to make sowing of rice seeds enriched with copper. This application should be carried out by wetting the rice seeds with 0,5 % water solution of the microelement with a semi-dry method, i.e. the rate of 10 liter working solution of copper in 1 ton of seed. The article proves the economic feasibility of enrichment of rice seeds with copper
