Garbar L. Optimization of the spring rape growth technology in the right-bank part of the Forest steppe zone of Ukraine

The process of crop and quality of rape seeds formation depending from biologically habits of variety, fertilization crop system and ways of macro- and microelements application, weather condition on chernozemic soil was the object of research. By the purpose of researches was to identificate sorts for reaction on fertilization, de-termination of optimal rates of mineral fertilizers and timeliness of foliar fertilizing with macro- and microelements for receiving high and stabile productivity of spring rape. Methods of researches: field, laboratory, statistical. The scientific novelty consists in determina-tion of peculiarity of forming the productivity of spring rape sorts of Mariya, Oksamyt, Kalynivskyj, Klitynnyj-8 depending on fertiliza-tion crop system and weather conditions in the conditions of right-bank Forest-steppe of Ukraine. The basic results of researches en-tered into manufacture. Branch - agriculture, crop production, edu-cational process
