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
