Okra plant leaf area was highest with the OBF-NPK mix (Table 2). The PM and Gliricidia leaves mixed with NPK had similar leaf areas. The manure-NPK mixes produced leaf areas comparable to those from plants receiving PM and Gliricidia, without NPK, and were higher than the control. Leaves from plants treated only with NPK and only with OBF were smaller than from the mixed materials. Controls had the smallest leaves.
