The paper highlights the study results concerning winter wheat influence on its yield formation under right-bank Forest-Steppe conditions of Ukraine depending on predecessors. Also, it has been found that the yield varies depending on soil tillage and fertilization systems.
The main role in solving the national food security problem plays grain farming development in which priority belongs to the winter wheat production, which is the most important crop in the plant growing, which occupies 40 % of the grain acreage and forms 45-50 % of gross grain yield in Ukraine.
The best varieties potential yields level of winter wheat is not yet fully implemented. Thus, Ukrainian farmers main task in the nearest years is to increase productivity and to ensure the winter wheat grain production stability.
To increase winter wheat yield and to grain production under climate change mitigation and energy savings requirements, search for ways to improve high-quality technology and its use tactics are required.
The research aimed at determining winter wheat sort influence on grain yield formation under right-bank Forest-Steppe conditions of Ukraine depending on predecessors, tillage methods and fertilization.
The studies were conducted during the 2011-2014 at the Bila Tserkva National Agrarian University experimental field, located in the right bank steppes area of Ukraine.
We studied three winter wheat varieties: Podolyanka, Yasochka and Bat`ko in five rotations and their impact on the yield, depending on the predecessors, tillage methods and fertilization
To increase winter wheat yield and to increase grain production under climate change mitigation and energy savings requirements, we conducted search for defining ways to improve high-quality technology and its use tactics.
The greater high-quality stock variety is, is the greater is the possibility of the yield increase due to optimizing the sorts placement in soil-climatic and agro-technical niches that meet them.
The results showed that Podolyanka, Yasochka and Father winter wheat varieties yield changed significantly in the research due to weather conditions during the growing season, and the predecessors influence (peas, soybeans, winter wheat), cultivation methods (differential) and fertilization system.
The leading direct action factor influencing the studied varieties yield are fertilizers methods.
Key words: winter wheat, sort, yield, predecessors, tillage methods, fertilizer system.
