摘要：
FIELD: agriculture.SUBSTANCE: invention relates to agriculture, specifically to technology of cultivating winter cereals. Method involves determining time of beginning of spring vegetation (VNVV) of winter cereals, collecting soil samples from 0–20 cm layer and vegetable samples with account sites of field in period of beginning of spring vegetation of plants, counting in all living stems with length > 10 mm, determining density agrophytocenosis (AFC), making a decision on value of planned yield. Additionally, extraction of soil samples from 20–40 cm layer, in which level of phosphorus and potassium modes of AFC is determined from content in soil movable phosphorus (P2O5) and exchange potassium (K2O), in soil samples from 0–20 cm layer, determining level of nitric AFC mode from content of nitrogen of exchange of ammonium (N-NH4), and determining optimum dose of first nitric fertiliser for winter cereals,calculated by formula:where dn = xn-Kn (difference between value of each factor and value of its constant), x is a factor, K is a constant of factor (average annual level of factor), Y is optimum dose of first nitric fertiliser, kg nitrogen in rate of application/ha, x1 is nitrogen content of exchange of ammonium (N-NH4) in soil, mg/kg, x2 is movable content of phosphorus (P2O5) in soil, mg/kg, x3 is content of exchange potassium (K2O) in soil, mg/kg, x4 is density AFC, stems/m2, x5 is planned productivity, centner/ha.EFFECT: method provides more accurate determination of optimum dose of first nitric fertiliser for winter cereals with due allowance for yield.5 cl, 2 tbl, 1 exИзобретение относится к области сельского хозяйства, а именно к технологии возделывания озимых колосовых культур. Способ включает определение времени начала весенней вегетации (ВНВВ) озимых колосовых культур, отбор почвенных образцов из слоя 0-20 см и растительных образцов с учетных площадок поля в период начала весенней вегетации растений, подсчет в них всех живых стеблей длиной >10 мм, определе
