Veneciano K.L. Frigerio Agrociencias production defoliation crudeprotein forage grasses deferred pasture The objective was to determine the effect of spring summer defoliation onyields, harvested dry matter composition and protein content of deferred materialfor 3 cultivars of Old World bluestem (Bothriochloa sp) and 1 of sideoats grama(Bouteloua curtipendula (Mich.) Torrey). Defoliation treatments -T1 (3 cuts anddeferring), T2 (2 cuts and deferring), T3 (1 cut and deferring) and T4 (completedeferring)- and participants (4) were disposed on split-plot with a factorialarrangement of treatments (n= 6). Dry matter yields of whole plant (WPY) and leave(LY) -kg ha-1 y-1-, crude protein content of leave (CP, %) and leave crude protein yield(CPY, kg ha-1 y-1) for accumulated values and for winter values (deferred material )were measured. Data were analyzed by Anova (proc. GLM, SAS) and means werecompared with Tukey test (p<0,05). It is conclude that Dahl (Bothriochloa bladhii(Retz.) S.T. Blake), for its higher LY, was the cultivar of major productive performan-ce.
