Water is a limiting factor for crop yields, for example yellow passion fruit, requiring from use of irrigation due to limitation of surface waters. This study aimed to evaluate irrigation levels and fruits quality in yellow passion fruit production in Semiarid conditions, thus an experiment was carried out. The seedlings were grown in greenhouse and transplanted in the field spacing 4 m x 2 m. The treatments studied were five water levels: 60; 80; 100; 120 and 140% from ETo, applied through drip irrigation with 4 repetition. The parameters evaluated were average fruit weight (g), yield (t ha-1), the pulp yield with seed (%), juice yield (%) and skin percentage (%). The results obtained in the experiment showed that the highest yield of hybrid passion fruit with average weight over 150 g, and the highest yield was obtained with the blade of 120% ETo. The yield of pulp with seeds was negatively affected by increased volumes of water for irrigation. Can use plant 120% ETo for the irrigation of yellow passion fruit 'IAC 273/277¿ to optimize production and improve fruit quality in semiarid conditions.
