Resumo
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: L 0 = 0 (not irrigated); L 40 = 40% Evaporation
of Class A Pan (ECA); L 80 = 80% ECA; and L 120 = 120% ECA. Coffee plants were fertilized with: A 0 = 0 kg
ha -1 (no fertilizer); A f = Alfertil ® applied by foliar application by a 5% solution; and A s = 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.
