Abstract
The effects of varying levels (0, 110, 220, 330, 440, and 550 kg P/ha) of phosphate application on some growth and yield parameters of African yam bean were studied. Plant dry weight under 550 kg P/ha treated soils with values ranging from 13.79 to 16.32 g per plant significantly (<0.05) differed from those of the control treatment, (12.79 g). Grain yield was enhanced following increased phosphate fertilization, with highest yield (1509.02 kg/ha) recorded in 330 kg/ha compared to those under 550 kg/ha treatments (1420.72 kg/ha).
Key word: Fertilizer, phosphate, Sphenostylis stenocarpa, yield.
