摘要：The experiment was conducted at the experimental Field of Sher-e-Bangla Agricultural University, Dhaka during the Kharif season from April, 2012 to August, 2012 to study the evaluation of some management practices for suppressing the insect pests and growth and yield of soybean. The experiment comprised with six different insecticides and one botanicals including untreated control viz. T1-Neem oil @ 3ml/L water, T2-Ripcord 10EC @ 2ml/L water, T3-Aktara 25 WG @ 0.3 mg/L water, T4-Sumialfa 5EC @ 2ml/L water, T5-Marshal 20EC@ 2ml/L water, T6-Control treatment were used as treatments. The experiment was laid out in Randomized Complete Block Design (RCBD) single factor with three replications. The maximum numbers of leaves, number of branch, maximum leaf length, number of flower, minimum number of infected pod, maximum number of healthy pod per plant, were found from the treatment Sumialfa 5EC @ 2ml/L of water. Similar treatment also produced the yield plot-1 (3.29 kg) and yield per hectare (3.65 t/ha) of soybean. Those results indicate that the Sumialfa 5EC @ 2ml/L of water showed the best performance on growth and yield among the all applied insecticide in this study.
