A simulation study relating the effect of the spatial arrangement of trees on the photon exposure above an associated crop (PEi) was carried out for an alley cropping system of the leguminous treeErythrina poeppigiana (Walpers) O. F. Cook with sequential maize-bean cultivation. These results were combined with estimates of the nitrogen supplied by prunings from different tree densities to rank the arrangements. A significant difference was found in the PEi between the east-west and north-south… CONTINUE READING
