Description

Grassland occupies some 89 % of the arable land in Ireland (anon., 1984) and of this approximately only 3 % is reseeded annually. Many permanent pastures have poor botanical com­position. Frame and Tiley (1988) pointed out that quantity and quality of secondary grass species are inferior to Lolium perenne. Nonetheless, there is evidence that permanent pastures have high animal production potential and that the large responses to reseeding in the first harvest year are rapidly lost (Wilkins et al., 1987). This paper compares new and old pastures under grazing and silage regimes.

Aspects of Reseeding Old Permanent Pasture
