The result showed that the liquid organic fertilizer with dose 10 l/ha macro fertilizer and 5 l/ha micro fertilizer were not significantly increased the growth and yield of rice plant. Liquid organic fertilizer with dose 75% SRI was significantly increased the leaf number than dose of 25% and 100% SRI.
