A trial was carried out at the Experimental Station of Pariquera-Açu, State of São Paulo, Brazil, on an organic soil previously limed, to determine the influence of chemical fertilizers in addition to compost on the yield of pepper cv. Agronômico 10-G. Chemical fertilization consisted of 0-0-0, 180-320-240, 360-640-480 and 540-960-720kg/ha of N, P2O5 and K2O. Organic fertilization consisted of 20t/ha of compost (basically 90% straw). There was no advantage on the use of organic fertilization alone. Chemical fertilization increased yield, number and average weight of fruits. The highest yield of marketable pepper fruits (33.2t/ha) and the best economic returns were obtained at rates of 360-640-480kg/ha of N, P2O5 and K2O.
