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

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.
