Abstract The purpose of this research was to determine the effect of soil amendment on the growth and productivity of several varieties of rice in newly opened rice fields. This research was conducted in Montasik District, Aceh Besar District, Aceh Province from June to September 2021. A factorial randomized block design consisting of three rice varieties Inpari 42, TG/IRBB27, and Koshihikari was set up as the first factor. Whereas the second factors consist of two levels of organic amendment by using manure 20 tons ha −1 and biochar 20 tons ha −1 . The results showed that the TG/IRBB27 was the best variety by producing plant height at harvest reaching 120.81 cm, the number of tillers 16.03 tillers, panicle length of 28.74 cm, grain weight per hill of 98.86 g, with yield potential reached 12.70 tons ha −1 . The best soil amendment was found with Biochar 20-ton ha −1 amendment that caused an increase in the number of tillers to 14.37 tillers and yield potential reached 9.82 tons’ ha −1 .
