The article presents the data of field experience which show that the increase in the yield of raw cotton when using the coordination compounds of trace elements of cobalt and copper on the optimal nutritional background –N250 P175 K125 increases by 4.5 and 5.8 quintals (q)/ha, respectively, relative to the cotton crop, grown without trace elements, and by 2.8 and 3.2 q/ha in the variants with the use of inorganic salts. Also, the results of research have established that the use of coordination compounds of trace elements has a positive effect on the course of physiological and biochemical processes and the yield of various cotton varieties. It is noted that the increase in yield obtained from the introduction of coordination compounds of trace elements, an average of three years of yield increase was from 12.4 to 17.7%, compared with the control. Coordination compounds Co-31, Co-34 and Cu-12 significantly improve the technological properties of the fiber and increase the oil content of the seeds of the nucleus. Thus, the greatest increase in cotton yield is observed in the variants with the coordination compound of cobalt -5.8 c/ha; the share of the first harvest of raw cotton in the variant is 74.6%, i.e. by 12.3% more than in the control variant, and in the variant with the coordination compound of copper is 4.3 c/ha per hectare compared to the control.
