Abstract

A nursery experiment was carried out in Ibadan (rain forest zone), Southwest Nigeria to study relative effect(s) of combined use of organo-mineral fertilizer (OMF) and cocoa pod husk ash (CPHA) on soil chemical properties, nutrient status and growth of coffee seedlings (Coffea arabica L.). Eight treatments: 5t/ha CPHA, 20 t /ha OMF, 20 t/ha OMF + 5t/ha CPHA, 15 t/ha OMF + 5 t/ha CPHA, 10t /ha OMF + 5 t/ha CPHA, 5 t/ha OMF + 5 t/ha CPHA and 400kg/ha Urea which translate to 6.25g CPHA, 25g OMF, 25g OMF + 6.25g CPHA, 18.75g OMF + 6.25g CPHA, 12.5g OMF + 6.25g CPHA, 6.25g OMF + 6.25g CPHA and 0.6 Urea per 2.5 kg of soil filled poly bag respectively with a control (no fertilizer) were applied to soil containing seedlings. The organic manures increased significantly [P
