Abstract
The interactive effect of (Parkia biglobossa) was investigated on the growth and yield of maize
(Zea mays) over a period of twelve (12) weeks at Ladoke Akintola Research farm Ogbomoso. The
experiment was laid out in Radomized Complete Block Design (RCBD) with 3 treatments and 3 replicates. Data collected were plant height, number of leaves, stem girth. Leaf area, canopy diameter, number of branches and were subjected to statistical analysis using analysis of variance (ANOVA) while the means were separated using Ducan’s Multiple Range Test DMRT at 5% probability level. There were significant differences in the number of leaves and number of branches of P. biglobossa (p≤ 0.05) of both sole tree and the intercropped. Intercropping affected stem girth and canopy diameter of the tested tree specie. The values obtained for stem girth with sole P. biglobossa (6.5 cm) were significantly higher than the intercropped (3.4cm). Higher numbers of leaves were obtained in maize +P. biglobossa intercrop (275.8cm2) compared to sole P. biglobossa (262.4cm2). Sole maize had higher grain yield (0.98 t/ha) than the intercropped maize + P. biglobossa (0.95t/ha) however maize + P. biglobossa had the highest percentage shelling (50.4) than sole maize (41.6). It was therefore concluded that there were positive interaction between P. biglobossa and maize plant. Hence, it could be recommended that there is need to encourage combination of maize and P. biglobossa at the early growth stage for efficient utilization of available land resources and for conservation of the P. biglobossa.
