Raja Uncak local rice in the Kapuas Hulu Regency, West Kalimantan Province. is very popular to neighboring country (Malaysia). Rice Raja Uncak is usually planted by farmers once a year in the traditional way and does not use inorganic fertilizers but uses litter from the Kapuas River. The purpose of this study was to increase the productivity of Raja Uncak local rice by giving several ameliorants. The research method used was in the form of a field experiment with a randomized block design. The treatments applied were T1 (Compost of organic litter from Kapuas River application 5 t ha–1), T2 (Biochar application 5 t ha–1), T3 (lime application 2 t ha–1), and (T0) (without ameliorant). The results showed that the treatment with 5 t ha–1 of compost delivers the best results and was significantly different from other treatments. Providing 5 t ha–1 of compost can increase the productivity of Raja Uncak local rice from 0.72 t ha–1 (Without ameliorant) to 3.14 t ha–1. Thus, the effort to provide ameliorant in the form of 5 t ha–1 of compost is recommended for the Raja Uncak local rice cultivation in Kapuas Hulu Regency.
