This is the first time in conditions of Semisavanna of Ukraine when mutual effect of winter wheat precursors and three complex growth-regulating preparations on the growth, development and yield of winter wheat grain has been studied. It has been determined that Antistress, Mars-EL and four amino acid complex preparations can be used for winter wheat growing technology with the aim to increase its yield both during the naked fallow sowing, and after a grain precur- © Позняк В.

The less significant but stable increase in yield of 0.27-0.59 t/ha is provided by complex growth-regulating preparations during sowing wheat over wheat. Use of the studied complex preparations with a wide range of action throughout the growing season had a positive effect on indicators characterizing growth, development and formation of winter wheat yield. The most effective was the joint use of Antistress and Mars-EL preparations (0.5-0.71 t/ha increase) and all the three drugs together (Antistress + Mars-EL + amino acid complex) when additional 0.59-0.81 t/ha of grain was obtained. Thus, our research has shown that use of new promising growth-regulating agents for winter wheat growing technology makes it possible to implement its genetic potential and increase yield more efficiently, which undoubtedly is of a great importance for agricultural farms specializing in production of this crop.
