The performance of different selected rice varieties was evaluated in this study to determine the suitability of a specific BINA-released variety for cultivation in a particular location. The focus was on an Aman season variety, and the experiment was conducted in farmers’ fields under the supervision of the Bangladesh Institute of Nuclear Agriculture (BINA) substation, Khagrachari. Three varieties were selected for the trial: Binadhan-12, BRRI dhan49, and Sylheti Pajam. The experiment followed a Randomized Complete Block Design (RCBD) with three replications. Sylheti Pajam exhibited the tallest plants, longest panicles, and highest straw yield, but had the lowest number of tillers per hill, effective tillers per hill, and grain yield. It also required the longest duration to reach maturity. BRRI dhan49 ranked second in terms of grain yield, duration, and straw yield. Binadhan-12, known for its fine grain quality, showed the highest grain yield with the shortest maturity duration, making it highly attractive to both consumers and local growers. While all three varieties showed potential for local cultivation, Binadhan-12 was preferred due to its high yield and short growth duration during the Aman season.
