The extreme changes in weather which resulted in disruption of shallots growth so that the impact of declining quality and productivity of the land in shallot planting. The study aimed to determine the effect of rice husk ash and potassium fertilizer (KCl) on the growth and production of shallots. The research design used was Split Plot Design in a factorial Randomized Block Design consisting of two factors, namely the factor of rice husk ash (A) as the main plot consisting of 3 levels: 5 t/ha (A1), 10 t/ha (A2 ), 15 t/ha (A3) and potassium fertilizer factor (K) as subplots consisting of 4 levels: 0 kg/ha (K0), 100 kg/ha (K1), 200 kg/ha (K2), 300 kg/ha (K3). The results showed that the best dose of rice husk ash and potassium fertilizer to the growth and production maximum of shallots were 15 t/ha and 300 kg/ha, respectively. Doses of rice husk ash and potassium fertilizer have not shown the optimum dose for to the growth and production maximum of shallots.
