Performance of orchardgrass (Dactylis glomerata L),perennial ryegrass (Lolium perenne L.) and white clover(Trifolium repens L.) associations
The aim of this study was to evaluate the forage yield of orchargrass (Dactylis glomerata L.) and perennial ryegrass(Lolium perenne L.) in monoculture and associated with white clover (Trifolium repens L.), in its second year ofestablishment. The treatments were: 20:40:40, 00:50:50, 40:20:40, 50:00:50, 20:70:10, 70:20:10 and 40:40:20 oforchard grass, perennial ryegrass and white clover, respectively. These associations were distributed according to arandomized block design with three replications. The variables measured were forage yield, plant height, radiationinterception (RI, %) and botanical composition of the harvested fodder (%). All treatments were defoliated by sheep(Suffolk x Dorset) according to each season of the year (five, six and four weeks in autumn, winter and spring-summer, respectively). The associations 00:50:50, 20:40:40, and 40:20:20 had the higher annual herbage yield producing22 % more than the grass monocultures and the 40:40:20 association which had the lowest DM yields (on average15,027 kg MS ha-1). Seasonal production throughout the year was distributed as follows: in fall-winter 40 % andspring-summer 60 % (P<0.05). White clover was the species with the highest percentage of harvested forage (44 %)followed by orchardgrass (39 %) and perennial ryegrass (17 %). In conclusion, some of the associations surpassedthe yield of grasses in monoculture; additionally, there was a differentiation in the seasonal forage production. Theinterception of solar radiation and plant height are good indicative of yield and therefore of harvest.
