The article presents data on the study of various forms, doses and methods of application of fertilizers used in the
early spring for feeding winter wheat grown in arid conditions of the Central Ciscaucasus. During the 10-year period
of study of optimization ways of winter wheat fertilization, we have not revealed a significant difference in the
effectiveness of the root fertilization and surface fertilization of winter wheat in earlyspringperiod.In years with
sufficient moisture supply, the highest yield was observed in options with root fertilization of the winter wheat. We
recommend the optimal dose of nitrogen for earlyspring fertilizing of winter wheat in arid conditions of ordinary
chernozems to be equal to 35 kg r.a.(rate application), which provides the maximum gain in yield of winter wheat of
the studied varieties by 16.3% and 17.4%, respectively.
