Influence of treated palm oil mill effluent sludge on maize (Zea mays) growth performance and gas exchange

The presence of abundant oil palm residues in Malaysia prompted the need to utilize this waste to avoid environmental pollution. This waste was abundant at the oil palm mill and accounted for almost 50% of production. The study was conducted to determine the morphological effect of Palm Oil Mill Eff...
