Ishchenko V. Agrobiological bases of increase of productivity of spring grain crops in the Northern Steppe

Object of research: processes of growth, development of plants of new grades of spring durum and soft wheat, triticale of spring and membranous and naked barley of spring; regularities of formation of their productivity at application of effective technological receptions of cultivation. Methods: field, laboratory and statistical. Results: The peculiarities of adaptive traits of plants are substantiated and the scientific bases of crop productivity formation using elements of bioadaptive technologies of growing spring hard and soft wheat, triticale of spring and membranous and naked and barley spring barley for rational use of bioclimatic potential of the Northern Steppe are developed. Peculiarities of realization of biological potential of new varieties of spring barley in cultivation after different predecessors, with local application of mineral fertilizers, crop protection system, inoculation of seeds with biological products, foliar fertilization with macro- and microfertilizers, and application of plant growth regulators are determined. Resource-saving bioadaptive innovative technologies for growing varieties of spring durum and soft wheat, triticale of spring and filmy and naked and barley spring barley have been introduced into production, which ensure high realization of plant productivity potential in the Northern Steppe of Ukraine. Novelty: solved the scientific problem of stabilizing grain production by scientifically substantiating and developing elements of bioadaptive technologies for growing wheat, triticale and spring barley, which are based on the management of growth and development and use of biological potential of crops taking into account agroclimatic changes. Field of use: agriculture.
