The use of organic fertilizers can contribute to improving the chemical, physical and biological properties of the soil, with its use having low environmental impact. The aim of this work was to evaluate the productivity and quality of yellow passion fruit in organic system combined with irrigation and input levels. A randomized complete block design with factorial scheme (3x2) with four replicates was used. The factors evaluated were: three input levels (fertilizers and alternative pesticides) and presence or absence of irrigation. Fertilization consisted of application of 5, 10 and 15 liters of organic compost per plant and 500, 1,000 and 1,500 g of limestone per plant for input levels 1, 2 and 3, respectively. Topdressing fertilization was split in two times: 118, 235 and 353 g.plants-1 of thermophosphate and 59.1, 118.20 and 176.40 g. plants -1 of potassium sulfate at levels 1, 2 and 3 of input application, respectively. Alternative pesticides were sprayed every 30, 15 and 7 days to levels 1, 2 and 3, respectively. The number of fruits per plant and productivity increased using input level 3 combined with irrigation. Input level 2 and 3 in the absence of irrigation increased the soluble solids content. Titratable acidity, TSS/TAA ratio and fruits classified as extra did not differ significantly among treatments. Using inputs levels 1 and 2 and absence of irrigation, the percentage of fruits classified as organic increased.
