Abstract
Research goal. Determination of the effectiveness of growth biostimulants in the technology of growing soft spring wheat in the northern forest-steppe of Ukraine to obtain high yield and grain quality. Methods. Field, laboratory research, mathematical and statistical analysis. Results. Under the conditions of the northern forest-steppe of Ukraine the effect of the complex application of elements of adaptive technology of cultivation, in particular, mineral fertilizers, protection system and biostimulants of plant growth on the productivity of soft spring wheat variety Nedra was established.The cultivation technology, which provided for the application of N45P90K90 before sowing and by N45 during IV and VIII stages of organogenesis against the background of ensiling the by-products of predecessor and integrated crop protection in combination with the use of biostimulants in the average years of research, received the highest yield of spring wheat - 4.08 t/ha. Yield increase with this technology compared to the control was 2.03 t/ha. Crude protein content under these growing conditions was 16.3 %, crude gluten – 32.8 %, which corresponds to the 1st class of grain quality according to DSTU 3768: 2019. At low production costs for purchase and application of biostimulants of growth (only 200 UAH/ha) the economic effect of their use varied from 0,85 to 1,6 thousand UAH/ha in different fertilization technologies of growing soft spring wheat of Nedra variety. The cost of 1 ton of grain was reduced by 0,20–0,57 thousand UAH. Conclusions. The average yield increase of spring wheat from biostimulants application was 0.2–0.35 t/ha depending on fertilization level in growing technology. иThe use of biostimulants in combination with mineral fertilizers, to a greater extent, influenced the increase in the weight of 1000 grains. At technology, which provided the introduction of mineral fertilizer in a dose of N45P90K90 before sowing and by N45 on IV and VIII stages of organogenesis on the background of encroaching by-products predecessor and integrated system of protection received the highest economic effect of biostimulants application – 1.6 thousand UAH/ha, for reducing the cost of producing 1 ton of grain at 0.33 thousand UAH.
