COMPLEX FERTILIZERS IN TECHNOLOGY OF BREWING BARLEY CULTIVATION

Abstract

The article presents the results of research (2007-2010) on sod-podzolic light loamy soil of high fertility levels on the study of different compound fertilizer forms and doses with trace elements (copper and manganese) and biologically active substances in mainly application them into the soil on the yield and quality indicators of brewing barley of Ataman and Brewery varieties. It is established that the use of complex fertilizer various forms with micronutrients and plant growth regulators in the technology of brewing barley cultivation has provided grain yield increase on 3,3-6,1 c/ha (by crop harvest 60,2-60 c/ha of barley Ataman variety and 42,7-46 c/ha - Brewery variety) in comparison with standard mixtures (by crop harvest of 56,9 and 42,7 c/ha). The best complex fertilizer marks with trace elements in these soils were: N:P:K = 9:13:18; N:P:K = 10:19:25; N:P:K = 13:19:25; N:P:K = 10:16:19 which provided the grain increase in the range of 4,2 to 6,1 c/ha with grain quality indicators (protein, starch content ) on the level of required standards.
