Maize was intercropped with 6-month-old Gmelina Root
Growth Potential (RGP) trials in various spatial arrangements at
Matalam, Cotabato Philippines, arranged in a strip-plot design
with three replications. Analysis of data showed significant
differences in all agronomic and morphological characteristics
of maize as affected by tree spacing but not to RGP classes.
Mono-maize crop were dominated significantly in all traits. Tree
spacing is related significantly with maize yield, weight of 500
seeds and biomass while RGP class is negatively related with
yield, weight of 500 seeds, biomass, leaf area, and leaf area
index.
