Abstract
Rice production has been forced to utilize non-tidal swamp, due to the increase in land conversion. This research incorporated nine rice accessions to be grown in natural non-tidal swamp area at Keramasan, Palembang, South Sumatera. Research field was prepared as usual by the local farmers and divided into 27 plots of 280 cm x 80 cm to fulfill Randomized Complete Block Design with 3 replications as blocks. Research identified that rice accessions might be classified into 3 groups of Low Growth Rate, Intermediate Growth Rate, and High Growth Rate accession, namely LGRA, IGRA, and HGRA. These groups have value of growth rate to keep up the increase in water surface, during flooding season, of < 5 cm, 5 to 6 cm, and >6 cm per week, respectively. The LGRA group consist of Petek (A5) and Senia (A6), the IGRA group consist of Bone (A1), Pelita Rampak (A2), and Sawo Rimbo (A7). The HGRA group consist of Kuning (A3), Siam (A4), Sawah Beling (A8) and Putih Olak (A9). Some yield components tend to decrease as the growth rate increase, and some vary depending on the accessions. For effective and efficient cultivation, apparently, farmers should consider growth rate and yield potential to decide which rice accessions to grow in their swamp.
