KCl fertilization is generally done to increase the productivity of porang tubers , but the continuous use of KCl can degrade soil fertility. Based on this, KCl needs to be replaced with organic fertilizer. This research aims to determine the effect and replacement of KCl with organic fertilizer which caused the highest porang yield. The research was held in BKPH Pojok forest area on March-July 2020. The research was using RCBD one factor. This treatment was the replacement of KCl with organic fertilizer with percentage 100:0%, 75:25%, 50:50%, 25:75%, 0:100%, and control in 4 replications. Observation parameters included fresh weight, storage weight, diameter, thickness, and chip weight of tuber. The data were processed by using ANOVA 5% and DMRT 5%. The results showed that organic fertilizer was able to replace the role of KCl and the usage of KCl and organic fertilizer was selected based on the highest yield that appeared with the same percentage (50% KCl : 50% organic fertilizer).
