The effect of madre de cacao (Gliricidia sepium) and ipil-ipil (Leucaena leucocephala) at different rates applied as surface mulch on corn was studied at Betinan Research Station, Zamboanga del Sur [Philippines]. The findings showed that either sources of mulch has increased corn yield significantly at any rates of applied mulch materials except for ipil-ipil at 5 t/ha with no phosphorus (P2O5) fertilizer being added. Even if the mulch application is increased to 30 or 40 t/ha, corn yield did not vary significantly with 20 t/ha applied mulch with P2O5 added and with the application of 100-40-0 kg NPK/ha (the recommended fertilizer rate for corn in Zamboanga del Sur). Generally, the results reveal that adding the right amount of organic mulches either Leucaena or Gliricidia could increase the yielding capability of corn even with or without the addition of P2O5.
