In trials with Pennisetum typhoides [= P. americanum] given 120 kg N + 25 kg P2O5 + 50 kg K2O/ha, av. rates of N uptake by plants at the tillering, jointing, boot, ear initiation, dough and maturity stages were 0.72, 4.82, 4.28, 0.42, 0.99 and 0.93 kg/ha day, resp., and rates of P uptake were 0.07, 0.81, 1.16, 0.79, 0.15 and 0.13 kg/ha day, resp. DM production at the 6 stages was 28, 303, 468, 226, 126 and 84 kg/ha day, resp. Tillering was the critical stage for N and P application, affecting DM and grain yields. Application of N together with P increased the P uptake. The initial build-up of nutrients in plants determined the amount of nutrients translocated from the vegetative parts to the ears
