Dry matter production response of coastcross (cynodon dactylon) (L.) pears) to sources and rates of nitrogen.

Dry matter production of a coastcross pasture grown on a dark red latosol (hapludox), in Sao Carlos. Sao Paulo State, Brazil, under tropical altitude climate, was evaluated. The goal was to verify the efficientcy of N rates as urea and ammonium nitrate: 0,25,50,100 and 200kg ha per cutting, in five periods. Both sources were equally efficient. The mean N rates, which produced 80% of maximum forage yield, were 78 and 58 kg N ha respectively, for urea and ammonium notrate, and were related to dry matter yields of 2,769 and 3,347 kg ha per cutting.
