Impact of Composted Oil Palm Wastes on Soil Physical Properties, Organic Matter Content and Growth of Oil Palm Seedlings Under Different Moisture Regimes

A greenhouse study was conducted at the University of Nigeria, Nsukka, to evaluate the effect of composted oil palm bunch waste for improvement of some soil physical properties, organic matter status and growth of oil palm seedlings under different water management conditions. The experiment was a 4 x 3 factorial fitted into the completely randomized design with three replications. It consisted of 2 fac-tors–composted oil palm bunch waste and irrigation intervals. Composted oil palm bunch waste was applied at 0g, 100g, 200g and 300g/seedlings/polybag. The different moisture regimes were imposed by observing irrigation intervals of 7days, 14days and 21days after irrigating the soil in the polybag to field capacity water content. The result showed that every 14-day interval of irrigation significant (P
