In the article results of an estimation of influence of norms of fertilizers on productivity are shown equally and specific crops and joint crops of corn and sorghum sugar on a silo. It has been established that in the Podillia conditions, with the introduction of mineral fertilizers in the norm N90 P90 K120, the cultivation of maize together with sorghum sugar provides 503 centners/ha of green mass and 135.8 centners/ha of dry matter. Compatible corn crops with sorghum sugar provided a greater yield of fodder units per hectare compared to one species sown corn.
