Dmutrenko O. Winter wheat productivity depending on the elements of growing technology in the conditions of northern Forest-Steppe

Subject of research - process of winter wheat different-ripe varieties productivity depending on fertilizing and protection system and peculiarities of their interaction in soil-climatic conditions of northern Forest-Steppe. Objective of research - to develop and improve elements of winter wheat varieties growing technology. Methods of research - field, laboratory, visual, quantity-weighing, calculating, analytical, economical mathematical. Process of productivity formation and grain quality such winter wheat varieties as Stolychna and Kyivska 8 depending on conditions and growing technology using leaf-feeding with fertilizer Ekolist Standard is scientifically substantiated. Elements of variety growing technology of winter wheat for producing high-quality grain taking into consideration farm resources that allows to get 7,61-7,88 t/ha of 1-2class grain quality and conditionally clear profit of 6716-6850 hrn/ha are developed. The results of researches are implanted in farms of Kyiv region on the area of 111 hectares in 2009. Field of using - agricultural production.
