Pros Sem Nas Masy Biodiv Indon 5: 267-271. New high-yielding varieties are a component of technology that plays an important role in increasing rice production. Two new high-yielding varieties, namely Inpari 30 dan Inpari 36, were tested the adaptability in the rice field of Sigi District, Central Sulawesi, to know its productivity and quality of yield. The research aimed to find out the performance of growth and yield of two new high-yielding varieties in Sigi District. The research was conducted in the irrigated rice fields of Oloboju Village, Sigi Biromaru Subdistrict, Sigi District, from June to October 2017. The research was designed using Randomized Block Design with 4 replications. The seeds are planted with jajar legowo planting system 2 : 1, spacing of 20 cm x 40 cm x 10 cm with the number of seedling is 2-3 per hole using transplanter equipment. Fertilization is carried out in a specific location with a rice field test equipment. The most suitable of new high-yielding varieties was Inpari 36 varieties with potential yield of 11.3 tons/ha of dry grain and followed by Inpari 30 varieties with potential yield of 7.2 tons/ha of dry grain.
