The use of fertilizers and preparations based on bacteria while growing agricultural crops has increased significantly in recent years. Growth in demand for biological preparations is predicted due to the global economic crisis and difficulties in purchasing mineral fertilizers. Fertilizers with strains of bacteria and fungi certified by "Organic-standard" are widely available on the market. In the experiment were studied efficiency of processing corn seeds of hybrid Harmonium (FAO Euralis 380) with bio-fertilizers in a form of powder VITAMIN Q7 and as liquids LEANUM. Also, during vegetation period, corn plants were treated with a LEANUM solution of 2 l/ha (per 200 l of water). The experiment was conducted on typical low-humus medium-loam black soil on loess-like loams on the experimental field of Sumy National Agrarian University (northern forest-steppe, Ukraine). It was found that influence of biofertilizers on the elements of corn productivity depends on the weather conditions of the year. In seed treatment liquid fertilizer LEANUM is more effective than powdered analogue VITAMIN Q7. Nourishment on the variants with seed treatment and without increased the weight of 1000 grains and the number of grains per cob.
