Description
The effect of nitrogen and phosphorus application on yield and sward structure as height and leaf, stem and dead forage composition of dwarf elephant grass (Pennisetum purpureum Schumach) cv. Mott was studied under field conditions and complementary irrigation, during one year at very dry tropical forest with a semiarid climate in Venezuela. The nitrogen (N) and Phosphorus (P) rate were 0, 150, 350, 450, kg ha-1 year and 0, 50 and 100 kg P2O5 ha-1 year respectively. The N rate increased the plant height (81.52 cm), leaf, stem and death production (10, 8.13, and 1.62 t DM ha-1 respectively) and cumulative total dry matter yield (19.8 t DM ha-1) from seven cuttings each 45 days. Neither P alone nor NxP interaction had any discernible effect on dry matter production.
