In course of the research there was studied efficiency of macro fertilizers, single-component and multicomponent fertilizers in chelate form on sod-podzolic light loamy soils. The research was realized in the conditions of the Republic of Belarus in 2011-2012 on the experimental field of Belarus State Academy of Agriculture. As a result of realized research it was revealed that increasing of nitrogen fertilizer doses in the basic application from N16 to N90 on the background P60K90 significantly increased the brewing barley (Hordeum vulgare) yield and the crude protein content in the grain, which not in one of the variants of the experiment did not exceed the permissible level (10.5%). The maximum grain yield of barley (53.1 kg/ha) on average for 2011-2012 was obtained at foliar feeding barley by complex preparation MikroStim Cu, which compared with the background N60P60K90 + N30 in top-dressing increased the yield of 7.4 t/ha with permissible crude protein content in the grain. Growth rates and dynamics of accumulation of dry matter by barley plants, the influence of macro and micro fertilizers on barley crop yield, grain quality, specific and total barley yield were presented.
