An experiment was done during the period of Kharif-I (Summer) season 2023 at Pakundia upazilla of Kishoreganj district in Bangladesh to explore the yield performances of sesame varieties developed by Bangladesh Institute of Nuclear Agriculture (BINA). Three replications of a Randomized Complete Block Design (RCBD) were used, where Binatil-1, Binatil-2, Binatil-3 were the different variations. The experiment’s findings showed that the genotypes significantly differed in terms of days to maturity, plant height, number of developed branches, number of pods, length of pods, pod breadth, seeds contain per pod, weight of 1000 seeds and yield of seeds. Binatil-1 contained the tallest plant (106.00 cm), whereas Binatil-3 was the shortest plant (78.50 cm). It was noted that Binatil-2 had the greatest number of plant-1 branches (5.05), whereas Binatil-1 had the least amount (2.20). Additionally, Binatil-3 displayed the highest number of plant-1 pods (96.76) whereas Binatil-1 provided the lowest amount (50.72). Binatil-1 had the largest pod  (3.62 cm), whereas Binatil-3 had the smallest (2.63 cm) size. It was noted that Binatil-1 displayed the greatest number of seeds in pod-1 (78.35). The highest 1000-seed weight was recorded in Binatil-2 (3.18 g), whereas the lowest weight was in Binatil-1 (2.92 g). The variety Binatil-2 had the highest seed yield (1.38 ha-1), whereas Binatil-1 had the lowest (1.25 ha-1). Among the cultivars, Binatil-3 matured in the fewest days (88), whereas Binatil-2 required the most days (96). Overall, Binatil-2 gave the significant growth and yield performance in Kharif-I (summer) season trial. Furthermore, it will be useful for Bangladesh to choose sesame genotypes with high yield potential and future breeding stock.
