Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka during Kharif-1 season (March – June), 2014 to study the effect of irrigation frequency and weed control methods on growth and yield of sesame (Sesamum indicum). The experiment was consisted of two treatment factors, viz., factor- A: four levels of irrigation frequency and factor- B: four levels of weed control methods. The experiment was laid out in a split design. The highest plant height (104.4 cm), number of leaves plant-1 (104.6), number of branches plant-1 (6.44), number of capsules plant-1(54.97), number of seeds capsule-1 (58.53), 1000 seeds weight (3.213 g), seed yield (1.413 t ha-1) and harvest index (29.26%) were obtained with the interaction effect of I3W2 (three times irrigation + two hand weeding). But the shortest plant height (78.18), lowest dry weight plant 1 (15.36 g), number of leaves plant-1 (65.11), number of branches plant-1 (4.789), number of capsules plant-1 (44.77), number of seeds capsule-1 (49.60), 1000 seeds weight (2.910 g), and seed yield (0.944 t ha-1) were obtained with the interaction effect of I0W0 (no irrigation + no weeding). Significant variations were found due to irrigation frequency, weed contr
