The objective of this study was to evaluate the effect of the irrigation and fertilization with Alfertil® on the yield of coffee crop. The statistical design used was in randomized blocks, with subdivided plots and four replications. The coffee plants received four irrigation levels: L0 = 0 (not irrigated); L40 = 40% Evaporation of Class A Pan (ECA); L80 = 80% ECA; and L120 = 120% ECA. Coffee plants were fertilized with: A0 = 0 kg ha-1 (no fertilizer); Af = Alfertil® applied by foliar application by a 5% solution; and As = Alfertil® applied in the soil surface with 100 g plant-1. The results show that the coffee productivity was influenced by irrigation and Alfertil® fertilization. However, only the different irrigation levels influenced significantly the yield of coffee crop. Irrigation levels that maximized productivity and yield of the plant was estimated at 60.08 and 70.20% ECA, respectively, and the plants fertilized with Alfertil® either foliar or soil application enhanced the productivity of coffee crop.
