ABSTRACT

An experiment was done during the period of Kharif-I (summer) season 2023 at Pabna district in Bangladesh to explore the yield and factors affecting yield of two sesame varieties developed by Bangladesh Institute of Nuclear Agriculture (BINA) against a local one. Three replications of a Randomized Complete Block Design (RCBD) were used where Atshira, Binatil-3, Binatil-4 were the different variations. The experiment’s findings showed that the genotypes significantly differed in terms of days to maturity, height of plant, number of developed branches, number of pods, length of pods, pod breadth, seeds contain per pod, weight of      1000 seeds and yield of seeds. Atshira contained the tallest plant (105.20 cm), whereas Binatil-3 contained the shortest plant (79.53 cm). It was noted that Binatil-4 had the greatest number of plant-1 branches (5.17), whereas Atshira had the least amount (2.12). Additionally, Binatil-3 displayed the highest number of pods plant-1 (95.66) whereas Atshira provided the lowest amount (51.75). Atshira had the largest pod (3.23 cm), whereas Binatil-3 had the smallest (2.48 cm). It was noted that Atshira displayed the greatest number of seeds in pod-1 (76.28). The highest thousand seed weight was recorded in Binatil-4 (3.25 g), whereas the lowest thousand seed weight was in Atshira (2.85 g). The variety Binatil-4 had the highest seed yield (1.36 ha-1), whereas Atshira had the lowest (1.21 ha-1). Among the cultivars, Binatil-3 matured in the fewest days (86), whereas Binatil-4 required the most days (95). At Binatil-4, significant growth and yield performance was found from Kharif-I (summer) season trial. Furthermore, it will be useful for Bangladesh to choose sesame genotypes with high yield potential and future breeding stock.
