Influence of various dozes and terms of application outside root top-dressing by cobalt and manganese on quality of green mass blue lupine cultivated on sod-podzolic light loamy soil is studied. Content increasing of the tested microelements in green mass blue lupine up to optimum values is noted at outside root top-dressing by cobalt and manganese sulfates in dozes on 50 g/ha active substance in a phase of the end of flowering - the beginning of grey beans formation. Positive influence of tested microfertilizers on the nutrients content in green mass established. Application of cobalt sulfate in a doze 50 g/ha has promoted increase in crude protein content on 7% in dry matter in comparison with background, but manganese sulfate – on 12% in the same doze. Content of crude ash in green mass of lupinus angustifolius was correspondent to the optimum indices. Application of microelements topdressing has allowed to increase in crude ash content in green mass on 0,82-1,64%. Topdressing has not rendered the essential influence on crude cellulose content in green mass. Research results have shown that microfertilizers application increases in crop rotations up to 20-27%, regulates the mineral nutrition of plants. It means that optimization of plants nutrition conditions relatively to macro- and microelements has allowed to increase their productivity up to optimum level
