The influence of organo-mineral fertilizers on the formation of productivity of strawberry integrated agrocenosis

Abstract

In 2012-2016 the research was carried out in order to study the infl uence of fertigation and foliar feeding by liquid organo-mineral and mineral fertilizers in chelated form on productivity of strawberry agrocenosis in unstable weather conditions. On average, it was revealed that over fi ve years of research the increase in biological yield on the variety Elsanta was 26.1 %, 27.1 % and 33.4 % in cases with foliar feedings by Raykat, Aminocat, Megafol. For Vima Xima strawberry variety, the yield increase was 16.9-29.0 %, however signifi cantly higher yield increase was revealed after Aminocat applying — 29 %. The use of liquid organomineral fertilizers containing nutritional element in chelated form in Elsanta variety plantations, on average over 3 years, was showed a signifi cant yield increase (12.5 %), in the variant with Kelik Calcium + Boron application and for Vima Xima strawberry variety in the the variants supplemented by Floron (19.25 %) and by Atlante Plus (11 %). High biological effi ciency was observed during the formation of productivity on organic and mineral fertilizers Raykat, Megafol, Aminocat, Megafol.
