【 摘 要 】

The objective of this research was to evaluate the productive capacity of orchard grass alone and associated with perennial ryegrass and white clover sown at different proportions. Treatments consisted of the following associations and monoculture: 100-00-00, 70-20-10, 50-00-50, 40-40-20, 40-20-40, 20-70-10, 20-40-40, and 00-50-50% of orchard grass, perennial ryegrass, and white clover, respectively. The eight treatments were randomly distributed into 24 experimental plots of 9 × 8 m according to a completely randomized block design with three replicates. On average, the associations that had the highest herbage yield in two years were 40-20-40, 20-70-10, and 20-40-40 with 21038, 20709, and 20073 kg DM ha−1, respectively, and the lowest herbage yield was registered by monoculture with 12793 kg DM ha−1. The associations with higher herbage yield exceeded that of monoculture by about 61%. Independently of the association, in summer, the highest percentage was found to be orchard grass and in winter, it was white clover, while perennial ryegrass had the lowest percentage throughout the study. The associations of grasses and legumes have higher herbage yield when compared with the monoculture of orchard grass. The legume has a better behaviour when it is associated with perennial ryegrass and worse with orchard grass.
