Abstract
Abstract Tidal swampland holds significant agricultural potential including cultivating rice. Farmers in these regions typically cultivate local rice varieties. Breeding rice techniques have led to the development of superior rice well-suited to thrive in tidal swamplands. This research was conducted on acid sulfate soil within a tidal swampland located in Terusan Karya Village, Kapuas Regency, Central Kalimantan, during the 2021 dry season. The study employed a completely randomized block design with two replications. The experimental treatments comprised nine high-yielding rice varieties: Inpari IR Nutri Zinc, Cakrabuana Agritan, Inpari 3, Inpari 32, Inpari 42, Inpari 47, Inpara 2, Inpara 8, and Inpara 10. The parameters were observed, including plant height, panicle number per hill, panicle length, and grain yield. The high-yielding varieties of rice planted in acid sulfate tidal swamplands exhibit varying growth and yield performances. Grain yields of rice ranged from 5.45 to 7.30 t ha−1 of dry-milled grain. The highest grain yield was shown by Inpari 3 (7.30 t ha−1) and Inpari 32 (7.04 t ha−1). High heritability values are indicated by the traits of dry harvest and milled grains, while wide variability is shown by characters such as plant height, panicle length, grain dry harvest, and dry milled.
