An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University during February to May 2019 to study the effect of weed management practices on the yield of different sesame varieties. The experiment comprised two factors; factor A: sesame varieties viz. Binatil-2, BARI Til-3 and BARI Til-4; factor B: weed management practices viz. no weeding, one hand weeding at 15 days after sowing (DAS), two hand weeding at 15 and 30 DAS, three hand weeding at 15, 30 and 45 DAS, and post-emergence herbicide application at 10 days after emergence (DAE). Weed parameters and most of the yield contributing characters and yield were significantly influenced by sesame varieties and weed management practices. Among the varieties, the highest seed yield (1.01 t ha-1) was recorded in BARI Til-4, whereas for weed management practice, the highest seed yield (1.26 t ha-1) was obtained in three hand weeding. In interaction, the highest seed yield (1.54 t ha-1) was found in BARI Til-4 with three hand weeding which was statistically similar to two hand with the same variety (1.48 t ha-1). Therefore, BARI Til-4 with two hand weeding at 15, and 30 DAS might be taken in consideration for obtaining higher seed yield in sesame.
