This paper describes the data obtained concerning the chloride concentration in coffee leaves. The application of potassium chloride furnished the following means: 843,3 ± 134,3; 4476,0 ± 356,4; 4812,0 ± 67 0,7 and 5149,0 ± 570,7 ppm of chloride, respectively, for the treatments K0 (no KC1 applied); K1(167 grams of KC1 or 100 grams of K2O); K2(335 grams of KC1 or 200 grams of K2O); and K3 (670 grams of KC1 or 400 grams of K2O). Symptoms of excess of chloride were not observed in this experiment.
