Abstract: A three year study was conducted in the rainy seasons of 2005, 2006 and 2007 at the Research Farm of the Institute for Agricultural Research, Ahmadu Bello University, Zaria, Nigeria, to evaluate character association and path coefficient analysis of maize (Zea mays L.) grown under legume incorporation and nitrogen. The results of this study showed that maize grain yield correlated positively and significantly with all measured characters. Path coefficient analysis indicated that plant height, total dry matter per plant, crop growth rate, cob length, number of grains per cob, 100-seed weight and stover yield showed positive direct effects on grain yield. Plant height and total dry matter per plant and 100-seed weight and stover yield gave the largest combined contributions. In growth characters, the highest individual contributions to grain yield were made by total dry matter per plant and crop growth rate. In yield characters, the highest individual contributions to grain yield were made by 100-seed weight and stover yield. Conclusively, total dry matter per plant, crop growth rate, 100-seed weight and stover yield should be considered for selection criteria in improving these varieties for better yield.
