In field experiment in chernozyom in the condi- tions of the Krasnoyarsk forest-steppe, the effect of complex fertilizers in recommended doses of appli- cation was compared. The effect of fertilizers, de- pending on their composition, on chemical compo- sition, the accumulation of macronutrients, gluten and exchange energy in the grain of spring wheat in Memory of Vavenkov was established. Yield lev- el of spring wheat in the field experiment was char- acterized as high. The maximum yield was ob- tained by introducing the aquarin 5 as a foliar top dressing. The second place for the collection of grain and straw took options with the introduction of ammonium phosphate and urea fertilizing wheat, which marked fairly large differences in comparison with the control. The use of foliar fertilizing with so- lutions of aquarin 5 and urea made it possible to adjust the nitrogen nutrition of plants in the early stages of plant development. The use of mineral fertilizers had an effect only on the accumulation of nitrogen by wheat plants, the content of this ele- ment in grain increased by 1.2 times, which posi- tively affected protein formation. Fertilized variants of the experiment on the content of phosphorus and potassium in wheat grains did not differ signifi-cantly. The removal of nutrients with the yield ex- ceeded the amount of these elements with fertilizer, which requires an increase in the doses of fertiliz- ers to realize biological potential of the wheat varie- ty to the Memory of Vavenkov. Wheat grain in all variants in terms of the quantity of gluten corre- sponded to the first class, which agrees with the varietal characteristics. The advantage of foliar feeding of aquarin 5 on complex yield characteris- tics, as well as economic and energy efficiency of its use was revealed.
