The aim is to determine the optimum combination of inorganic fertilizer and organic materials for increasing the productivity of rice crop (Oryza sativa L.). The experiment was conducted in February- June 2015 in Kebadu, Sanggau, West Kalimantan, Indonesia. The study area was located at 00°0.08,785’N north latitude and 110°0.07,175’E east longitude with ultisol soil; the altitude is 32 m above sea level, rainfall level ranges between 185-267 mm month-1, and the solar radiation is 375.49- 452.58 cal cm-2 day-1. This study used a factorial randomized block design. The first factor was the inorganic fertilization (without fertilizer, inorganic fertilizer 50%, 100%, and 150%) and the second factor was the addition of organic materials (EM4 2 l ha-1, chicken manure 2 t ha-1, and manure 2 t ha-1 + EM4 2 l ha-1). Results showed that the application of chicken manure and a combination of chicken manure+EM4 could reduce the need for inorganic fertilizer NPK by up to 50% with productivity that ranged from 4.18-4.20 t ha-1; this is relatively similar to 100% and 150% inorganic fertilizer NPK, and can increase the harvest by up to 68% compared to the no-NPK inorganic fertilizer.
