Application of Multiple Fertilizers and White KNO3 to Increase Pepper Plant Growth

Abstract

Pepper production was decresed, it is caused by quality varieties and less intensive maintenance.  Furthermore, price of pepper is unstable. Fertiliation is one of the efforts to increase pepper production. This study aims to obtain the right dose of compound fertilizer (NPK) and white KNO3 to increase production of pepper plants. The experiment using 5 combinations of fertilization : 0,5 g NPK (control), 1 kg NPK combined with 2% white KNO3 each plant, 1,3 kg NPK combined with 2% white KNO3 each plant 1,6 kg NPK combined with 2% white KNO3 each plant. Variables observed for cultivated pepper plant: panicle length (cm), number of panicles, number of segment, and number of branches. Application of 1,3 kg NPK combined with 2% white KNO3 each plant visualized the best of panicle length (4,38 cm), number of panicles (34), number of segment (49,8), and number of branches (17,2).
