S.  aInteractive N supply and cutting intensity effect on leaf nutritive value of C4 grasses.h[electronic resource]  c2014  aMonocultures of six warm-season perennial grasses were compared in a factorial field design of two N levels (zero and 300 kg N ha-1 year-1) and two cutting intensities (i.e., the residual kept was 30% and 50% of the canopy height at 95% light interception). The main components of plant nutritive value were measured in two successive growing periods. The species studied exhibited a significant range on leaf lamina quality and leaf proportion. Overall, changes on these parameters were greatest for N fertilizer than cutting-intensity treatments.  alight interception  anutritive value  aresponse to management1 aGIOSTRI, A. F.1 aBARRO, R.
