In the conditions of the Republic of Belarus there was studied action of new single-component and poly-component micro fertilizers on crop yield and quality of maize. The research was realized in 2008-2009 on the experimental plot of Belarus Academy of Agriculture in Mogilev region on sod-podzolic moderately cultivated soil. The soil of the experimental plot had a reaction of slightly acidic soil medium (pH in KCl 5.7 – 5.8), insufficient humus content (1.70 – 1.71%), increased mobile phosphorous content (186 – 202 mg/kg), medium and increased content – mobile potassium (197 – 213 mg/kg). It was found that the application of Adob Zn and complex microfertilizer Vitamar on the background N90P70K120 + N30 increased productivity of maize green mass on 39,0 and 33,0 c/ha. Adob Zn and Basfopliar 36 increased productivity of green mass of maize on the background N120P90K150 + N30 on 35 and 63 c/ha, respectively. The maximum content of crude protein was obtained after application of a complex micro fertilizer Basfoliar 36 on the background N120P90K150 which has made 10.3%. The maximal yield of crude protein was 9.3 c/ha. The greatest profit was in variant with application of Vitamar and Adob Zn on the background N90P70K120 + N30 which has made 562.5 and 617.7 thousand Belarusian rub/ha at profitability of 83.1 and 87%.
