Plaksa V. Productivity of spring triticale depending on culture cultivation practices in the conditions of the western Ukrainian Polissya

Subject of research - the process of spring triticale productivity formation depending on fertilizing system and seeding rates. Objective of research - to prove scientifically the technological elements of spring triticale varieties growing depending on their biological peculiarities. Methods of research - field, morphophysiological, chemical, physical, dispersive, comparative calculating. Peculiarities of forming and realization biological potential of spring triticale varieties Aist Kharkivs'kyy and Arsenal depending on seeding rates and fertilizing system in soil-climatic conditions of Western Polissia of Ukraine are determined. Techonology of spring triticale growing on turfy-podzolic sandy loam soils that provides obtaining 4.5-4.8 t/h high-quality grain is scientifically substantiated and improved. Scientific treatments are implanted in agro formations of Volyn' region on the area of 100 hectares in 2008-2009. Field of using - agricultural production.
