aref2 In the conditions of forest steppe black soils of the Middle Volga Region in a stationary field experiments a system approach to the performance evaluation of various autumn tillage systems and growth regulators for spring wheat cultivation out providing an increase in the yield productivity and reducing the energy costs was carried. The followinf variants of the experiments were studied: factor A- 2-phase surface tillage 20-22 cm deep, minimum tillage 12-14 cm deep; factor B - no seed treatment (control), treatment with prepartions Circon, Novosil, Energia M. preseeding treatment of seeds with growth regulators positively influenced the yield productivity of spring wheat (an increment up to 0,31 t/hectares by applying a growth regulator Energia M) promotes increase in the content of protein and gluten in grain. The greatest factor of power efficiency (2,58) at spring wheat cultivation was achieved by minimum tillage in a combination with presowing treatment of seeds with a growth regulator of Energia M, therefore, the application of such technology promotes increasing the yield and quality of grain together simultaneously decreasing the energy costs.
