It was evaluated the effect of three levels of potassium fertilization on physical and chemical characteristics of fruits of nine genotypes of sour passion fruit (Passiflora edulis Sins. var. flavicarpa Deg.). The design used was based on randomized blocks in factorial scheme 9 x 3, being nine genotypes of passion fruit and three levels of potassium fertilization (0, 640, 1280 kg of K2O ha-1.year-1), summing to 27 treatments, with four replication. It was observed more influence of the potassium over physical characteristics of the sour passion fruit. The total yield was linear with application of potassium. There was a square effect in the doses of potassium over the fruit length, in the length/diameter ratio, in the peel thickness and in the mean number of seeds per fruit.
