Abstract

Pekinensis cabbage is one of the main cultures of East Asia, but in recent years, it has been in high demand in Ukraine, due to its high productivity, early maturity and the content of vitamins and mineral salts that are necessary for people. The purpose of the study was to determine the effect of mineral nutrition on the yield of pekinensis cabbage hybrid Storido F1. The studies were conducted during the 20142016 years on the experimental field of the Horticulture and Storage Department V. V. Dokuchaev KNAU in the conditions of the Left-Bank Forest-Steppe of Ukraine. The article presents the studies' results of the mineral nutrition influence on the pekinensis cabbage productivity in the left-bank forest-steppe of Ukraine. Studies have shown that the introduction of the nitroammophoska (NPK) (the main) + ammonium nitrate (in top dressing) + complex 20 + 20 + 20 + ME + potassium sulfate (foliar top dressing in two periods) provides yield growth up to 81.3 t / ha. The usage of the specified complex of mineral fertilizers helps to increase economic and bioenergy efficiency. Net profit amounted to 352.1 thousand UAH / ha, with a high level of profitability 647.2 %. With the increase in the solids content up to 7 %, the energy accumulated by the economically valuable part of the crop increases to 70852 MJ / ha, and the bioenergy efficiency coefficient reaches 3.8
