The objective of this study was to determine the chemical composition of corn silages produced in soils originated of arenito caiuá (AC) and basalto (BA) located in North of Paraná. A complete randomized experimental design with two treatments (soils AC and BA), with 18 and 13 replications were used, respectively. The contents of dry matter (DM), mineral matter (MM), crude protein (CP), crude fiber (CF), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), calcium (Ca), phosphorus (P) and total digestible nutrients (TDN) were determined in the samples. The variance analyses did not show significant differences between soils for all components analyzed in the silages. The principal components analysis explained 65% of the variability between corn silages samples of different cultivars originated of soils AC and BA. The more important parameters for characterization and differentiation between cultivars, regardless of soil’s type, were EE, TDN, ADF, NDF and CF.
