A garden of Passiflora edulis var. flavicarpa was plantes 19 Aprill 994. The purpose of the planting was to compare two types of trellis systems: cross or "T" and back or fence. The cross shaped trellises were made up of metal pipes 1.5 m. high from the ground to top crossed by .9 m. pipes at a hèight of 1.2 m. Three wires ran parallel to each other from cross to cross, separated .3 m. from one another. The back trellis system used the same metal pipes 1.5 m high, without the cross. Two wires ran from pipe to pipe, one .9 m. and the other 1.2 m. from the ground. This type of trellis system is less expensive. The experiment of two treatments (the trellis systems) and three replications. Each treatment carried 45 plants, that is, 15 plants per replication per treatment. The vines were planted 3.7 m. within the row, and 3.7 m. between rows, using five plants per row. Results were analysed by LSD tests. Cross shaped trellises do promote a significantly higher production (290 kgs vs 226 kgs). The reason why so many local growers use the fence trellis system may have more to do with reducing expenses.
