Description Pennisetum glaucum cv. CIVT grown on a Labucheri soil at Sadoré, Niger in 1989-90 was given 15 or 45 kg N and 4.4 or 17.4 kg P/ha. Increased N rate increased total DM by 13%, N uptake by 63% and P uptake by 29%. Increased P rate increased total DM by 100%, N uptake by 80% and P uptake by 140%. In 1989, with adequate rainfall, grain yield was 0.6 t/ha with 15 kg N/ha and 0.9 t with 45 kg N, whereas in 1990, with low rainfall, grain yield was lower and unaffected by N rate. Grain yield was higher with the higher P rate in both years. N concentration in the stover was increased by increased N rate and decreased by the higher P rate. Plant P concentration was higher at the higher P rate. Mean total DM yield was 2.75 t/ha, partitioned into grain (18%); animal feed consisting of chaff, immature panicles, upper stover and tillers (41%); and middle and lower stover components for soil conservation (41%). Partitioning was not affected by fertilizer rate. Of the total N (33.4 kg/ha) and P (5.2 kg/ha) uptake, 32 and 40% were contained in grain, 41 and 40% in animal feed, and 27 and 20% in components for soil conservation, respectively
