The objective of work was to evaluate the productivity and physical characteristics of fruits of yellow passion fruit (Passiflora edulis Sims) grafted on Passiflora gibertii in different planting densities. The experiment was carried in Adamantina, SP, Brazil, from May 2009 to April 2010, adopting the experimental design in randomized, with six treatments and four replicates. The treatments were different planting spacing: T1 - 1.0 m (3.125 plants/ha); T2 - 1.5 m (2.083 plants/ha); T3 - 2.0 m (1.563 plants/ha); T4 - 3.0 m (1.042 plants/ha); T5 - 4.0 m (781 plants/ha); T6 - 5.0 m (625 plants/ha). The distance between the lines was 3.2 m for all the treatments. The variables evaluated were: diameter of fruits, number of fruits, weight of fruits and productivity. The planting density did not favor diameter and weight of fruits. It was observed a smaller number of fruits in smaller spacings, which were compensated by productivity.
