Lentil is the most popular pulse crop in terms of both area and consumer choice in Bangladesh. However, the lack of situation and cultivar specific seed rate recommendations are among the problems that constrain its productivity. Therefore, a field experiment was conducted during 2020 to determine the optimum seed rate for sowing of lentil mutants/varieties on the growth and yield contributing characters of advanced lentil lines/variety developed by Bangladesh Institute of Nuclear Agriculture (BINA). The study looked at four seeding rates: 25 kg ha-1, 30 kg ha-1, 35 kg ha-1 and 40 kg ha-1 on three advanced lentil mutants viz. LM-99, LM-118, LM-206-5 in comparison with one checked variety Binamasur-8. In all three locations, the seed yield of lentil mutant was notably different, with Ishurdi producing the highest seed production (2.09 t ha-1). The mutant LM-99 generated the maximum seed yield (1.66 t ha-1) among the several advance mutants/variety, followed by LM-118 (1.58 t ha-1). Among the various seed rates, 35 kg ha-1 produced the highest seed yield (1.64 t ha-1) in the 2020 season. The findings suggest that when another management techniques were followed correctly, the mutant line LM-99 produced the maximum yield at a seed rate of 35 kg ha-1.
