The productivity of winter rape depending on nitrogen nutrition and growth regulating fertilizers under climate change conditions

Yevhenii Domaratskiy Valerii Bazaliy Oleksandr Domaratsky

This article presents the results of five-year field research, conducted in the climatic conditions of the Yelanets district of the Mykolaiv region on ordinary black low-humus soils, determining the productivity of winter rape. The study proved that the productivity of the hybrid Kronos is higher than of the Chornii Veleten variety by 0.49 t / ha, or by 17.0%. The results of the field research indicated that the yields of winter rape reach the maximum values after the early spring treatment with Nitrogen nutrition (dose N90) in combination with the two -fold foliar application of the growth- regulating substance Helafit Combi®; the increase in the yield of the variety was by 0.79 t / ha and of the hybrid by 1.11 t / ha.
