Field trial was conducted at the Institute of Agricultural Research and Training, Moor Plantation, Ibadan, Nigeria in 2002 and 2003 to assess the effect of Ogun rock phosphate (ORP) amended with cow dung (CD) manure on the growth and yields of maize and okra in intercrop relayed with cowpea on an Aquic Arenic Haplustalf. Significant treatment effects were observed in plant height and leaf area of maize and okra whereas stem girth was not significantly affected in either crop. The percentage leaf P concentration of maize, okra and cowpea were significantly (p
