## Abstract
Abstract This study aimed to determine the growth and production of rice in various water management systems, the application of a combination of fertilization and planting systems. The research was carried out from June to September 2016 in Ponrangae Village, Sidrap Regency. The trial used a split-split plot design with water management system set as main plot, a combination of nitrogen fertilizer as subplot and planting system as sub-sub plot. Two water management system applied were stagnant and intermittent management systems. Three fertilization packages were used by applying different combination of inorganic and organic fertilizers. The sub-subplot consisted of three planting system namely tiled planting system, 2:1 and 4:1 legowo planting systems, respectively. The results show that the interaction of intermittent water management system with the application of 50 kg ha −1 Urea + 250 kg ha −1 NPK + 2.5 L ha −1 liquid organic fertilizer resulted in the highest number of productive tillers. Interaction of intermittent water management with the application of 50 kg ha −1 Urea + 250 kg ha −1 NPK + 2.5 L ha −1 liquid organic fertilizer and 4:1 legowo planting system produced highest weight of 1,000 grains. Application of 50 kg ha −1 Urea + 250 kg ha −1 NPK + 2.5 L ha −1 organic fertilizer with the 4:1 legowo planting system showed the highest harvested and milled dry grain.
