In course of the research there was studied the influence of various levels of cobalt content in podzoluvisol sandy loam soil, doses and cobalt fertilizers on the yield and quality of blue lupine (Lupinus angustifolius). The research was realized in the conditions of the Republic of Belarus in 2011-2012 in a field experiment in state enterprise 'Suvorov Experimental Base' (Uzda, Minsk region (Belarus)) on sod-podzolic sandy loam soil. As a result of realized research it was revealed that higher efficiency (grain increase 3.3 and 2.9 c/ha at profitability of 530 and 490%) provided the application introduction of MikroStim-Cobalt in foliar fertilizations in a dose of 0.025 kg/ha of active substance at low (0.9 mg/kg) and average (2.0 mg/kg) levels of the cobalt content in a soil. Cobalt foliar fertilizers increased cobalt content at the grain according experiment embodiments to 0.48-0.60 mg/kg of dry mass, or by 11.6-22.4% as compared with the background embodiments. The levels of cobalt content in soil, economic efficiency of foliar fertilizations of blue lupine by cobalt fertilizers on various cobalt content soils were presented.
