Abstract
The article presents the results of studies about the effectiveness of spring barley crop cultivation with modern retriever preparations in the background of mineral fertilizers carried out in 2013-2017 on the southern bleak soils in the Ukrainian Steppe. The effects of varietal characteristics of spring barley and nutrition options on the height of plants and grain yield. It was determined that for growing spring barley under presowing cultivation of mineral fertilizer dose N30P30 (background) and using foliar application crops at the beginning of the exit plants up and beginningearing phase to complex organic fertilizers Organic D2 and Escort - bio in the favorable conditions for the formationthe larger linear sizes of plants and the highest level of grain yield of the studied varieties are formed. For example, on average, over the years of research, spring barley plants of fertilizer variants were formed 3,22-3,25 t/ha of Adapt variety, 3,33-3,37t/ha of Stalker variety and 3,56 – 3,61t/ha of Aeneas variety. Percentage, which exceeded control indicators 25,8-27,0; 26,6 - 28,1 and 27,1 - 28,9% respectively. We must consider that the best from all investigated varieties of winter wheat for their complex of indicators was the variety Aeneas.
