Fig. 1. Grass x month interaction means (4 yr) for (a) forage dry matter (DM) accumulation and (b) forage DM mass. There were no differences (P > 0.05) between grasses for DM accumulation at any month. For comparison of grasses within month for forage mass, ns indicates grasses are not different (P > 0.05), * and ** indicates difference (P < 0.05 and P < 0.01, respectively). For comparison over months within grasses, means followed by the same letter are not different (P > 0.05).
