Abstract: | The research article presents the results of five-year field studies conducted in the conditions of the steppe zone on ordinary black low-humus soils (47.629, 32.079) to determine the productivity of winter rapeseed under the influence of early spring nitrogen nutrition in combination with environmentally friendly combined chemicals. Field experience was based on a three-factor scheme, where: factor A is early spring nutrition with nitrogen in a dose of N60, N90 and without nutrition; factor B is foliar treatment of plants with Wuxal® and Helafit Combi® twice during the growing season of winter rapeseed and a control option-spraying of plants with pure water. Foliar treatments of winter rapeseed plants with chemicals were performed twice with a field sprayer: the first at the end of the second decade after the start of the resumption of spring vegetation; the second in the phase of the beginning of budding-flowering. The consumption rates of the chemical Wuxal Mikroplant® was 4.5 kg ha-1, and Helafit Combi® was 1 l ha-1; the outflow of working fluid is 250 l ha-1. Factor C was the morphobiotypes of winter rapeseed: the Chornii Veleten variety, the originator of which is the Vinnitsya State Agricultural Research Station of the National Academy of Agricultural Sciences of Ukraine and the Kronos hybrid, the originator of which is seed company NPZ Lembke, Germany. Studies have established that the yield of various morpho-biotypes of winter rapeseed reaches its maximum when applying early spring nitrogen nutrition with a dose of N90 in combination with double application of foliar nutrition of plants with the combined growth-regulating chemical Helafit Combi®, the yield increase of the variety was 0.79 t ha-1, and of the hybrid - 1.11 t ha-1 © 2020 Ecological Society of India.
