Establishment of a bovine/Quercus silvopastoral experiment in lowland Ireland.Short, Ian; McAdam, J.; Culleton, Noel; Douglas, Gerry C. (CAB International, 2005)A silvopastoral experiment was established at Teagasc in County Wexford, Ireland, in 2002 with oak (Quercus robur L.) in an alley design and bovines. The experiment includes some treatments with trees produced with an enhanced root system (RPM). The treatments are: (1) control pasture plots; (2) RPM agroforestry (400 stems/ha); (3) conventional agroforestry (400 stems/ha); (4) RPM forestry (6600stems/ha; and (5) conventional forestry (6600 stems/ha). The trees were successfully established and cattle were successfully managed in combination with the trees. In the first year, height growth of bare-root oaks was significantly greater in the forestry treatment compared to the agroforestry treatment and, overall, RPM oaks were taller than bare-root plants. Among the RPM trees, the agroforestry system resulted in a greater stem diameter than those in the forestry plots. Height increment was greater for RPM trees than for bare-root trees.
