The experiement was carried out to examine the production performance of 3 local Sulawesi aromatic upland rice varieties planted with the alley cropping system at various planting distances pattern in Sampano Village, South Larompong District, Luwu Regency, South Sulawesi from February to June 2022. Plant spacing and selection of more adaptive varieties was one aspect for testing. The plants were laid out in a Split Plots Design in a factorial Randomized Completely Block Design. The main plots were 3 local varieties of Ngapa, Sassa, and Latimojong. Subplots were planting spacing consisting of random spacing (spread), 25 cm x 25 cm, 20 cm x 20 cm, and 15 cm x 15 cm. The results showed that 15 cm x 15 cm was the best spacing for planting local aromatic upland rice varieties in the alley cropping system which produced 1,433.24 kg dry grain weight per hectare, while Ngappa variety outperformed Sassa and Latimojong by registering 1,350 kg/ha.
