The five substrates were: (S1) 80 percent bovine manure+20 percent subsoil material; (S2) 60 percent bovine manure+20 percent subsoil+20 percent vermiculite; (S3) 80 percent bovine manure+5 percent coarse sand+10 percent vermiculite+5 percent rice husk; (S4) 50 percent earthworm humus+30 percent subsoil+20 percent vermiculite; and (S5) 100 percent commercial substrate. The three fertilizers were: (A1) slow-release fertilizer (15:10:10 NPK+micronutrient) at 8.33 kg/m3; (A2) 1.0 kg P2O5/m3+0.5 kg KCl/m3+6 top dressings of 0.5 percent urea, 0.75 percent MAP, 0.2 percent KCl, 0.35 percent ZnSO4.H2O, 0.15 percent H3BO3 and 0.3 percent copper oxychloride; and (A3)2 kg P2O5/m3+2.0 kg NH3SO4/m3+0.5 kg KCl/m3+0.5 kg fritted trace elements/m3+6 top dressings of 25 g NH3SO4 and 60 g KCl. S5, S4 and S1, together with A1, reduced the intensity of brown eye spot in coffee. Plant height, root and shoot dry matter weights were highest in S4+A1. A3 was the best fertilizer treatment independent of the substrates. S5+A1 and S5+A3 gave the highest shoot nutrient content in coffee.
