Abstract
The results of 2-year vegetation studies devoted to the study of the existing prerequisites for treating seeds (PTS) with solutions of flax selenium, vanadium, tungsten and iodine on the yield and its structure, as well as indicators of the quality of wheat grain are presented. The experimental crop was grown on soil with different supplies of available phosphorus and was grown in an artificially created drought. The effectiveness of microelements was most realized under conditions of low phosphate content in the soil. The use of solutions of sodium selenite, ammonium vanadate, ammonium tungstate and potassium iodide helps to increase the weight of wheat grain by 14, 11, 13 and 7% relative to seed treatment with distilled water. Under stress conditions, persistent sodium selenite has the best effectiveness - grain increase of 11%.
