The results of white melilot annual agrocetnoz of drought resistance evaluation are adduced. Thus, white melilot annual common biological features as a crop with moderate requirements to moisture, its varieties can differ substantially in adaptability to drought. This crop has valuable next genetically determined adaptive morphological and physiological characteristics associated both with the ability to make fuller soil moisture reserves using by means of more vigorous root system and its ability to reduce evaporation. Thus, the accumulated scientific potential and best practices of melilotus albus medik cultivation in non-irrigated chernozem steppe zone of the Middle Volga Region allows us to conclude that melilotus albus medik is fairly drought resistant and reliable crop for its cultivation in the cereal field rotations in the region. This paper proposes the set of cultural practices enable to get guaranteed seed yield at least 0.5 t/ga under dry conditions. These include - accommodation clover crops after winter harvesting using the main improved plowed fields processing type; minimizing spring tillage both their number and the depth of treated layer, use for sowing crop varieties that differ in length of vegetation ; maneuvering of clover sowing terms in the fields from early to late optimally within reasonable period; creation of fine lumpy soil surface by row treatments during crops maintenance; purity crops from weeds maintaining by means of efficient agricultural methods and herbicides. Such agricomplex best accumulation focus, saving and most economical use of natural water resources - the basis of consistently high yields both green mass and melilotus albus medik seed in non-irrigated conditions of the Middle Volga Region.melilotdrought resistanceplasticitywater applyingbiological productsдонникзасухоустойчивостьпластичностьводопотреблениебиопрепараты[Глуховцев, В.
