Kalens'ka S. The agroecological and biological fundamentals of winter rye and triticale production intensification in the Ukraine Forest-Steppe

The winter rye and triticale varieties of new generation. The working out of agroecological and biological foundations of winter rye and triticale production intensification in the Ukrainian Forest-Steppe on the basis of the principles of adaptive plant growing. The research methods are special and generally scientific. The physiologo-ontogenetic features of new rye and triticale variety productivity potential formation and realization depending on the growing conditions are revealed the varietal types with the high adaptability level are identified, the biological and agroecjlogical principles of winter rye and triticale production intensification in the Uukrainian Forest-Steppe are worked out. The adaptive processes of new winter rye and triticale variety growing which secure the obtaining of winter rye grain yelds at the level 5,5-6,5 t/ha, of triticale ones - 6,0-7,5 t/ga are designed and applied to production. The chart of green conveyor link wich the triticale variety use that allows to increaset he conveyor productivitu, feeding quality and to extend the period of its functioning by 20-30 day is worked out. The author's developments are introduced at the farms of the Kyiv, Khmelnythsk and Chernigiv Regions over a total area 1900 ha. The annual economic efficiency of development introduction made up about Hr 720-1220 thou. The field of application is agriculture.
