Rice (Oryza sativa L.) has become one of the main food crops in Indonesia. Rice productivity plays an important role for the supply of the community on a national scale. The application of NPK fertilizer can be a solution. The objective of this study was to determine the response of NPK compound fertilizer “Compaction DGW” on rice yield. The experimental was design using a Randomized Block Design (RBD) that consisted of 3 treatments and 3 replications, on 2,5 m x 4 m (10 m2) plot. The NPK compound fertilizer used for this study was “Compaction DGW”. The treatments included K0 (control), A2B1 (200kg of NPK fertilizer + fertilizer grain size > 1 mm), and A2B2 (200 kg/ha NPK fertilizer + fertilizer grain size < 1 mm). The variable observed was the production of dry grain. The results showed that the application of NPK compound fertilizer “Compaction DGW” with grain size >1mm and <1mm had no significant effect on increasing the dry grain weight. However, NPK compound fertilizer “Compaction DGW” produced higher dry grain weight compared to the control.
