The objective of this work was to evaluate four genotypes of temperate grasses in Arapongas, PR. The plantation was realized on 2007 April, using the follow species: black oat common (Avena strigosa Schreb), black oat (Avena strigosa Schreb) IAPAR 61, white oat (Avena sativa L.) IPR 126 and Italian ryegrass (Lolium multiflorum Lam.). The plantation was realized in paddocks, aimed 12 repetitions for each specie.The production of dry matter/ha (DM/ha) to black oat, black oat IAPAR 61, white oat IPR126 and Azevem were respectively: 1,36; 0,86; 1,17 e 0,67 ton of DM/ha. In the region evaluated, under conditions of drought during the deployment, the black oat common was more productive than others, but in relation to chemical composition, Black oat IAPAR 61 stood out with respect to the Black oat common, with higher levels of crude protein (CP) present in MS and also lower content of CP withheld on neutral detergent fiber (NDF) portion. The IPR126 oat, despite the small number of studies has demonstrated good results in many areas better to the common oat.
