A collaborative study between the International Centre for Research in Agroforestry (ICRAF) and Misamis Oriental State College of Agriculture and Technology (MOSCAT) compared several forage legumes and grasses as contour hedgerow species. The trial focused on how the species compared in reducing soil erosion, influencing annual crop yields, and their relative competition with the associated crops. A 5 x 3 factorial experiment was laid out in a strip-plot design in randomized complete blocks. The five hedgerow species of Flemingia congesla, Slylosanles scabra, Panicum maximum and Veliveria zizanoides, and an open-field control were the vertical factor. The three pruning management practices of prunings removed, uniform application, and skewed application across the alleyway (2/3, l/3, 0, and 0 on the four inter-alley zones from highest to lowest elevation) were the horizontal factors. The annual double-crop system was upland rice followed by maize in the alleyways. The hedgerow systems reduced soil erosion between 67 and 95%, with the grass species tending to be most superior alternatives for soil conservation. F. mycrophylla provided the highest annual pruning biomass (7.22 t/ha). Grain yields and total dry matter of upland rice and maize in the hedgerow systems did not differ consistently from those observed in the open field control. P. maximum reduced yields significantly, due to severe competitiveness. The hedgerow species rankings from lowest to highest in competitiveness were S. scabra, V. zizanoides,  congesla, and P. maximum. Skewed application of pruning biomass and crop residues to the upper alleyways to ameliorate upper-alley scouring showed no superiority compared with a uniform application.</style></abstract></record></records></xml>
