In the conditions of the Republic of Belarus in 2007-2010 on sod-podzolic light loamy soil there was realized a determination of different compound fertilizer forms and doses with trace elements (copper and manganese) and biologically active substances at their main application into the soil, and their influence on yield and quality indicators of brewing barley (Hordeum vulgare) of Ataman and Brewery varieties. As a result of research it was revealed that use of complex fertilizer of various forms with micronutrients and plant growth regulators in the technology of brewing barley cultivation made it possible to provide grain yield increase on 3.3-6.1 c/ha (with crop yielding capacity of 60.2-60 c/ha of barley Ataman variety and 42.7-46 c/ha - Brewery variety) in comparison with standard mixtures (with crop yielding capacity of 56.9 and 42.7 c/ha). The best complex fertilizer was marked with trace elements in these soils: 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.
