Description:	The effects of P fertilizer placement methods were investigated during eight consecutive crops of a corn-cowpea annual rotation. Treatments included comparisons between rates of broadcast P (0, 22, 44, 88 and 176 kg/ha) applied before the initial corn-crop, in factorial combination with banded P rates (0, 11, 22 and 44 kg/ha), applied to each crop.
