Leaf Nutrient composition: Plants treated only with Gliricidia leaves had the highest contents of N and P, while leaves from plants treated with the mix of Gliricidia and NPK had lower N and P contents (Table 3). Poultry manure alone produced leaves with N and P that were lower, as did plants receiving the PM-NPK mix. When OBF was used alone, it produced leaves that had N and P contents of 4.69 and 0.63%, respectively; plants receiving the OBF-NPK mix produced leaves with N and P contents of 4.96 and 0.53%, respectively. The OBF used alone produced leaves with the highest K content, followed by plants treated with Gliricidia leaves.
