Summary. High efficiency of mineral fertilizers in the Middle Predura-leagues reached only in strict compliance with the following conditions of crop turnover, which annually provides reseeding perennial legumes, not less than 15% of arable land or 25% of the area of grain crops; cultivation of crops in the same field crop rotation is not more than two years; planting early spring crops in the earliest date; with simultaneous application of a row of compound fertilizers; the optimum methods of sowing the seed rate of winter rye, winter wheat and oats – 6 million, barley – 5 million pieces germinating seeds per 1 ha, method of sowing straight line, the depth of sowing seeds 3-4 cm; application of micronutrients – procestion seed treatment or spraying plants in the tillering phase; receptions care of crops: root fertilizing nitrogen fertilizers winter grain crops new – spring in the tillering phase, spring crops – to vskhorows with simultaneous harrowing, spraying in the tillering phase herbicide tank mixture and micronutrients; cleaning techniques – single phase, with a preliminary desiccation. Efficiency of fertilizers under the action-lyvanii early spring crops determine the average daily air temperature in order for the period of sowing – wax ripeness. In yields between spring crops and the mean daily temperature for the period of sowing – wax ripeness exists negative tion close correlation. Dependence of the yield of barley from Toros average daily air temperature for the period sowing – waxy ripeness is described by the regression equation Y = 115,7 – 5,4 X.
