Resumo: This work aimed to evaluate the influence of irrigation on the nutritional status of coffee, after the irrigation with wastewater from the processing of its fruits (ARC). The amount of ARC applied for fertigation was calculated based on its potassium concentration after passed through an organic filter, and has been established the dose of 66.4 g of potassium per plant, corresponding to approximately 2 times the recommendations of potassium fertilization, that is 80 g K2O plant-1 for annual application in coffee shrub. Two treatments were established: the first (L1) was applied the dose of ARC in coffee plants in May, June and July and the second treatment (L1 *) was applied in the same period, the same dose, but continuing with irrigation until December 1. The data were subjected to analysis of variance with the application of the F test, at 10% probability. Based on the results obtained, it can be concluded that the irrigation of coffee with ARC, whether or not irrigation from August to December, provided a proper coffee nutrition in relation to potassium, iron and zinc; levels of nitrogen, phosphorus and manganese above the levels considered appropriate and calcium and magnesium below that deemed appropriate and continuity in irrigation, after being subjected to fertigation with the ARC did not alter the concentration of macro and micronutrients, except for copper in the coffee leaves.
