The results of field research of the fodder productivity of mixed crops depending on the level of nitrogen feeding and biopreparations are presented. The cultivars are: oats (Avena sativa), spring wheat (Triticum aestivum) and lupine (Lupinus). The influence of nitrogen on the content of raw protein in oats, wheat and lupine grain in pure and mixed seeds is analyzed. Raw protein content in cultivars' grain is shown. Productivity of the pure and mixed seeds of the oats, wheat and lupine depending on biopreparations is evaluated. It is established that for mixed crops the optimal variant is the application of acting substance of mineral nitrogen in the doze of 40 kg per ha and inoculation of legume component by sapronit, because output of the fodder units amounts to 4.68 tons per ha, output of raw protein increase on 0.646 tons per ha and the content of digestible protein increase on 107.82 g per fodder unit.
