Содержание и вынос элементов минерального питания озимой тритикале в зависимости от норм высева семян

Abstract

The article deals with the issues of maintenance and removal of mineral nutrition elements by plants of winter triticale on gray forest soils of the south-eastern part of the Volga-Vyatka zone, depending on the seeding rate and variety. The question of establishing the optimum density of sowing, the area of food for grain crops served as the object of study by many researchers [2,3,4,5,6]. The urgency of the issue of creating optimal sowing density is explained by the fact that the factors that determine the magnitude of the yield are constantly changing. Therefore, the study of patterns of formation of yield and removal of nutrients in connection with seeding rates remains an eternally new research topic. With a good harvest, winter triticale consumes and alienates a large amount of nutrients from the soil. With an increase in the seeding rates, respectively, the removal of mineral nutrients increases, and the seeding rate is important for the formation of a given density of productive stalk and removal of mineral nutrients. In production, these elements of technology are often underestimated and often unjustifiably overestimate the seeding rate, which is not necessary, since the really possible yield is achieved at an optimum seeding rate with minimal seed consumption.
