Winter wheat productivity depending on the cultivation technology elements in the Southern Steppe of Ukraine
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 103, Issue
Abstract
The article presents the results of studies on the effectiveness of treating winter wheat crops with modern growth regulators against the background of mineral fertilizers. The experiments were carried out in 2011–2016 on southern black soils in the Southern Steppe of Ukraine. We studied the influence of varietal characteristics of winter wheat and nutrition variants on the formation of yield structure and grain yield. It was determined that fertilization with the presowing tillage of two winter wheat varieties at a rate of N30P30 (background) and foliar dressing of crops with preparations Organic D2 and Escort-bio at the beginning of spring vegetation and stem elongation created favorable conditions for the formation of the best indicators of yield structure, and hence the highest level of grain yield of the studied varieties. For example, on average for the years of cultivation, in the given nutrition variants, grain yield of the Kolchuga variety was formed at a rate of 4.42−4.48 t/ha, and grain yield of the Zamozhnist variety was at a rate of 4.96−4.99 t/ha. These indicators exceeded the control by 52.9−55.0%, and 62.6−63.6%, respectively. Zamozhnist variety turned out to be the best of the studied winter wheat varieties in a set of indicators.
