Organomineral fertilizer in coffee plant (Coffea arabica L.): Fertilizer levels and application times

Coffee (Coffea arábica L.) is a fundamental agricultural commodity in the Brazilian economy, demanding high amount of nutrients for good vegetative development and productivity. The tested hypothesis was that use organomineral fertilizer promotes coffee production due to greater availability N, P, K soil. objective this study was: (i) monitor efficiency rates; (ii) determine with application. A developed applications four rates (75%, 100%, 125%, 150% recommended P2O5 rate), three forms parceling (one, two, fertilizer), one control (100% mineral). Yield, soil, leaves, plant were monitored. Results showed presented win-win scenario adequate disposal residues sources agriculture promoting yield from 49.5 (mineral fertilizers) 53.5 sc ha-1 organomineral). height, diameter stem, canopy quadratic response optimal fitted at 127; 140; 140 %, respectively, but there no direct effect on yield. split promoted contents P mainly when associated higher rates. increased application indicating used more efficiency.
