The size and yield of fruit are important in the physical quality of the fruits destined for markets and industry. An experiment was performed to evaluate the form, peel strength and yield of fruits of yellow passion fruit plant produced in substrata with bovine bio-fertilizer and mulching, irrigated with saline water. The treatments were designed in three random blocks using a 2 x 2 x 2 factorial arrangement; irrigation with non-saline (0.50 dS m-1) and saline (4.50 dS m-1) water, with and without application of bovine biofertilizer and with and without mulching. The passion fruit fruits were harvested when 30% of the peel was yellowish; we evaluated the diameter of the longitudinal cavity (length), diameter of the equatorial cavity (width), fruit form index, peel strength and juice and pulp yield. The substrate with bovine bio-fertilizer and mulching irrigated with high salinity water reduced the diameter of the longitudinal and equatorial cavity, the fruit form index and increased the firmness of the peel of the fruits of the yellow passion fruit plant. However, the use of the bovine biofertilizer and mulching irrigated with non-saline water increased the diameter of the equatorial and longitudinal cavity and the fruit form index.
