    The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during April to August 2015. BARI Dherosh-1 was used in this experiment. The experiment consisted of two factors viz., Potassium fertilizer as K0: 0 kg K2O/ha (control), K1: 60 kg K2O/ha, K2: 90 kgK2O/ha and K3: 120 kg K2O/ha; and Gibberellic acid (3 levels) as G0: 0 ppm GA3 (control) G1: 60 ppm GA3, G2: 90 ppm GA3 respectively. The experiment was laid out in Randomized Complete Block Design with three replications. All the parameters were significantly influenced by different levels of potassium and gibberellic acid. Due to the effect of potassium, the highest yield (19.04 t/ha) was observed from K3 and the lowest yield (12.11 t/ha) from K0. In case of Gibberellic acid, the highest yield (17.08t/ha) was found from G2 and the lowest yield (16.01 t/ha) from G0. From growth, yield and economic point of view, it is apparent that the application of 120 kg K2O/ha with 90 ppm GA3 was the best for growth and yield of okra.

    Interaction Effect of Irrigation Frequency and Weed Control Methods on Growth and Yield of Sesame Crop
    (International Journal of Plant & Soil Science, 2024-09) Islam, Zohirul; Islam, Md. Shahidul; Syfullah, Khalid
    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
