Abstract
The study uses randomized complete block design in determining the light regime under 7 year old Eucalyptus deglupta as hedgerows with Zea mays underneath. The result shows that the mean Photosynthetic Active Radiation (PAR) was highest at 1200 hr. and lowest at 1500 hr. across treatments (Eucalyptus hedgerows) and cropping season. The solar radiation in the 1x3m and 1x9m hedgerow spacing were lowered by 56% and 46%, respectively compared to the sole maize plot across growing period and cropping season. The total mean height and diameter increment of Eucalyptus at the end of the study (two cropping season) were not significantly different. The canopy diameter of Eucalyptus in the wider hedgerow spacing is more spacious than that of the narrow spacing. The grain yield of maize was found higher in sole maize plot than that of the hedgerow treatment. However, the yield is not statistically difference. In agroforestry, light management powers the long-term sustainability and enhances socio-economic profitability of the system. These can be done through appropriate and systematic designs of hedgerows trees that consider the temporal and sequential compatibility of the hedges with the alley crops.
