Abstract

The yellow passion fruit (Passiflora edulis f. flavicarpa Deg.) by it rusticity rapid return of money applied and the preference by market it is a crop with economic viability in more part of area of the Brazil. In this direction an experiment was carried out in Coronel Ezequiel Country area semi-arid fron Rio Grande do Norte State, Brazil, in randomised blocks in order to evaluate some yield comportaments of the plants under irrigation with saline water (3,4 dS m-1), using the factorial desing 4 x 22 referring at planting distance between plants in line of 3, 6, 9 and 12 m, in soil no and with mulching of apexe of the hast principal to attain the sustentation wire. The increase of planting distance of the plants in line provided increase of numbrer fruits by plant, the average mass the of fruit but decreased the passion fruit plants yeild.
