An experiment was carried out during the raining season of the year 2007 at the Teaching and Research Farm of Oyo State College of Education (Now Emmanuel Alayande College of Education, Oyo), Lanlate Campus, to investigate the effect of geometric row arrangement on the growth and yield of cowpea in a maize-cowpea intercrop. There were 1:1, 1:2 and 2:1 maize/cowpea row arrangement with a sole crop of cowpea as control. The experiment was laid on out in a Random Complete Block Design (RCBD) with three replicates, No significant difference among the growth parameter (plant height, number of leaves and number of branches) intercropped and the sole cowpea plants (p<0.05). However cowpea intercropped with maize at 1:1 row arrangement recorded highest grain yield per plant and consequently per hectare than those of 1:2 and 2:1 row arrangement, though not significant difference from them. It is hereby recommended that cowpea and maize should be planted at 1:1 row arrangement.
