ABSTRACT: Demand for rice as a source of food in Indonesia continues to increase in line with the growth of population, while the capacity to produce paddy rice increasingly limited. One of the efforts is to develop upland rice by utilizing the dry land with organic fertilizer application.  The research was conducted in North Buton using split plot design. The main plot was the treatment of manure dosage consisting of 4 levels of treatment and the second factor of local upland rice cultivars as a subplot consisting of 22 cultivars.  Production characters were observed and assessments are panicle length, grain number, number of grain content, wet grain weight, dried grain weight, grain weight per culm, and grain yield (t ha^-1). The results showed that the yield potency of local upland rice cultivar in North  Buton ranged from 3.11- 4.97 t ha^-1 and the treatment of organic fertilizer can increase the yield components of upland rice.
