A field trial was conducted since 1965 at the Pariquera Açu Experiment Station, State of São Paulo, to study the effects of the presence and absence of fertilizer on black pepper (Piper nigrum L.). In 1973, recently mature leaves were collected in summer, fall and winter in order to verify the effects of the treatments on the foliar concentration of macro and micronutrients. Summer sampling showed effect of fertilizer treatments on the concentration of phosphorus, potassium, and copper. Fall sampling showed effect only for potassium and no effect was observed in the winter. When the average contents of nutrients from fertilized and not fertilized treatments were compared, only potassium revealed differences by the Scheffé test.
