The authors evaluated the growth performance of three cover crops: calopogonium, centrosema, and siratro intercropped with gmelina seedlings. The criteria used were number of leaves, vegetative length, and biomass. Findings showed that centrosema performed better in terms of number of leaves (545), vine length (73.570 mm), and total biomass (93.38 gms) compared to calopogonium and siratro. Centrosema was not as adversely affected by intercropping with gmelina seedlings, although gmelina seedlings showed adverse influence on the total biomass of calopogonium and root biomass of siratro. Gmelina did not contribute significant phenols to the soils to a level toxic to the plants nor caused adverse change to the soils in terms of organic matter and pH
