The effect of black polyethylene mulch and soil tillage intensity was determined on yield and quality of drip irrigated melon. The field trial was carried out in Mossoró, Brazil. The experimental design was randomized complete block in a factorial scheme with three replications. Two soil tillage methods were evaluated (strip tillage or tillage of the entire area) and tillage depth (20; 30; 40 and 50 cm), with split plots with or without mulch. Fruits were classified in export type, internal market type and rejected, to determine total yield and the yield of each type, number of fruits and fruit mean weight. Pulp firmness, total soluble solids, pulp thickness and fruit shape were determined. Results showed a decrease in pulp firmness with black plastic mulch. Strip tillage did not influence any studied characteristic. Yield of both export type and internal market melons was influenced by tillage depth. While deep tillage increased yield of export type melons, it reduced internal market yield.
