Intercropping includes cultivating of two or more crop species simultaneously on the same filed. Benefits of intercropping can be achieved only if complementary crops are combined, which results in a higher and more stable yield in regard to sole crops. The competition of proso millet (M) and soybean (S) in different intercrop combinations (S-M, SS-MM, SS-MMMM), simultaneously testing influence of bio-fertilizer on them, was studied. In regard to competitive ratio and agressivity, all combinations showed soybean as dominant and millet as dominated specie. Since SS-MM combination has significantly separated from other two, with high values of competitive ratio and agressivity for soybean and low for millet, it can be concluded that ratio and planting pattern had significant influence on obtained results. Bio-fertilizer didn’t express greater impact comparing with intercropping, which influence was much more pronounced. Soybean showed its highest competitive ability in SS-MM treated with Coveron (3.36), while average aggressivity for this combination was 0.95. In contrast to soybean, in this combination millet showed its lowest values. Anyhow, deeper studies are desirable to find out the most productive combination for forage biomass production.
