Description
Crude protein (CP), Ca and P concentrations and in vitro dry matter digestibility (IVDMD) of irrigated dwarf elephantgrass (Pennisetum purpureum cv. N-75 Mott) as affected by the factorial combination of N (0, 150, 300 and 450 kg N/ha/year) and P (0, 50 and 100 kg P205/ha/year) fertilization was evaluated in a tropical dry forest in Zulia State, western region of Venezuela. A randomized complete block design with three replications was used. Soil was a low-fertility sandy-loam Udic Paleustalf (pH 6.1). Nitrogen fertilization did not influence (P>0.05) any of the variables. Mean CP, IVDMD, Ca and P were: 8.13, 61.3, 0.26 and 0.33 %. Phosphorus fertilization only influenced forage Ca content, which decreased (P<0.05) from 0.30 to 0.23 % as applied P rate was increased. The NxP interaction was not significant (P>0.05).
