Abstract:
Passion fruit (Passiflora edulis) is one of Indonesia's fresh fruits highly favored by both domestic and international consumers. Its production can be increased by applying KCl fertilizer. This study aims to determine the response of KCl fertilizer on the growth of passion fruit in lowland areas. The research was conducted at the Bosowa University Experimental Garden located in Bontoramba Village, Pallangga District, Gowa Regency. The study was designed as an experiment using a Randomized Block Design. The treatments applied were different doses of fertilizer: K1 (control), K2 (1.5 g/plant), K3 (3.5 g/plant), and K4 (4.5 g/plant). The results indicated that the application of KCl fertili er at a dose of 1.5 g/plant tended to have a better effect on the growth of the main stem length, stem diameter, number of leaves, and number of branches in the plants.
