Vinasse is liquid waste from ethanol production. Amount of Vinasse is increased as much as ethanol product. This research aims to observe the effect of vinasse incubation and potassium fertilizer on growth and yield of red chili (Capsicum annuum L.) Branang variety. This research had been conducted in the TriDharma farmstation, Faculty of Agriculture, Gadjah Mada University, Banguntapan, Bantul, Yogyakarta from October 2012 to February 2013. This research was arranged in Randomized Completely Block Design (RCBD) with two factors. The first factor was vinasse incubation which five levels were: no incubation, 5 days incubation of vinasse, 10 days, 15 days and 20 days. The second factor was potassium fertilizer rate which were three level without potassium fertilizer, 125 kg/ha of potassium fertilizer and 250 kg/ha potassium fertilizer. The experiment was 15 units with 3 replications. Data were analyzed by using variance analysis (ANOVA) with 95% significant level. If there were significant differences followed by DMRT (Duncan Multiple Range test) with a confidence level of 95%. Relation between 2 factors was analyzed by correlation analysis. The results of this experimental showed that incubation of vinasse till 20th days did not increases of pH, amount of nitrogen, phosphor, potassium and organic matter of vinasse. Vinasse which had been incubated increased leaf area, and plant dry weight, but it didn�t to yield crops. Either potassium fertilizer dosage 125 kg/ha and 250kg/ha or without potassium fertilizer did not give significantly effect on plant growth and yield of red chili.
