In the conditions of the Republic of Belarus there was studied influence of different forms of zinc and boric trace fertilizers on yielding capacity and nutritive value of grain of maize (Zea mays) presented by a hybrid Almaz (FAO -190) of the German selection (KWS company). It was determined in the field experiments in 2009-2010 that the usage of zinc in dose of 150 g/ha and barium in dose of 50 g/ha in sod-podzolic soil into foliar application of 6-8 leaves phase on agro mineral system increases grain yield of corn on 7.3-9.4 ts/ha (6,3-8,1%). Thus according to the influence on yield the learning species (zinc and barium) and its forms (mineral, chelate, organic-mineral) of trace fertilizer were equal. Nutrient content, gross energy and metabolically energy in corn grain under the influence of trace fertilizer does not change essentially, while the gathering of digest protein increases in 1,4-1,5 се/ha and metabolically energy increases in 16,1-19,5 GJ/ha.
