Kudryavytska A. Agrochemical substantiation of fertilizers use under winter and spring wheat growing in crop rotation on meadow-chernozem soil of the Northern part of the Forest Steppe zone of Ukraine

The object of research is a character of changes in nutrition regime of meadow-chernozem calcareous coarse sand-loamy soil on loessic loam and productivity of cultivars of winter and spring wheat using traditional kinds of fertilizers and new composite one "Kristalon special" as a foliar dressing accordingly to stages of organogenesis; cultivars of winter wheat Myronivska 61 and spring wheat Myronivska yara. The aim of research consists in studying of long-term fertilizers application in a crop rotation and application of a new kind of composite fertilizer "Kristalon special" on a nutrition regime and productivity of winter and spring wheat cultivated on meadow-chernozem calcareous coarse sand-loamy soil on loessic loam. Methods - field, laboratory, standard chemical, agrochemical, instrumental and statistical methods. The novelty consists in studying rules, agrochemical substantiation of influence of long-term fertilization in a crop rotation and application of a new fertilizer "Kristalon special" fora yield, quality of grain and baking-technological parameters of flour of cultivars of winter wheat Myronivska 61 and spring wheat cultivar Myronivska yara on meadow-chernozem calcareous coarse sand-loamy on loessic loam soil in conditions of the Northern part of the Forest-steppe zone of Ukraine. Results of research -the system of fertilization of new cultivars of winter wheat Myronivska 61 and spring one Myronivska yara of increase of productivity of meadow-chernozem soil, of obtaining of stable yield of high quality have been developed. Area - Agriculture.
