The experiment was conducted at the Research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, from February 2014 to June 2014. BARI Til-3 variety developed by Bangladesh Agricultural Research Institute (BARI), Gazipur. This experiment consisted of two factors; Factor-A: four levels of nitrogen viz. (i) N₀ (Control), (ii) N₁ (80 kg ha^-1), (iii) N₂ (100 kg ha^-1) and (iv) N₃ (120 kg ha^-1) and Factor B: four levels of phosphorus viz. (i) P₀ (Control), (ii) P₁ (20 kg ha^-1), (iii) P₂ (30 kg ha^-1) and (iv) P₃ (40 kg ha^-1). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on different parameters such as the number of capsules plant^-1, number of seeds capsule^-1, the weight of 1000 seeds, seed yield ha^-1 and stover yield ha^-1. The study reveals that a combination of different levels of nitrogen and phosphorous have a significant influence on the yield of sesame. Highest seed yield ha^-1 of sesame (1652 kg) and highest harvest index of sesame (37.33%) were recorded from N₃P₂ (120 kg N ha^-1with 30 kg P₂O₅ ha^-1). Therefore, the results suggest that the combined use of 120 kg N ha^-1 and 30 kg P₂O₅ha^-1 gave the highest yield of sesame.
