not to water logging or severe drought. It
produces high yields of palatable fodder,
responds well to manure and dies if
continually grazed close to the ground and
needs rest late in the growing season (FAO
2003). Cutting height as well as N fertilizer
application influences the dry matter yield of
herbage harvested from pasture swards
(Olsen 1974, Tudsri et al. 2002, FAO 2003,
Baatar 2008). The effect on grass
productivity of differential cutting heights is
conflicting. Langille and Warren (1961) and
Clapp et al. (1965) have shown that
increased yields can be obtained by lowering
