To evaluate the inoculant "Graminante", two field experiments were carried, in the 1996/97 cropping season, with com crop, out at FUNDACEP FECOTRIGO, in Cruz Alta, RS, Brazil. The commerciat product was tested isolated and in association with nitrogen fertilization. The treatments were as follows: l) Check without inoculation and without nitrogen fertilizer (N): 2) "Graminante" inoculam; 3) Nitrogen fertilizer apptied at the planting date and broadcasting. ; 4) "Graminante" imculant + N fertilizer ai planting date and broadcasting. 5) "Graminante" inoculam + N fertilizer at planting date; 6) "Graminante" inoculam + N fertilizer broadcasting. The parameters evaluated were: number ofplants and ofspikes, plantheight and grain yield. The inoculam "Graminante" studied did not show influencefor the com crop.
