A field experiment was conducted at farmer’s field of Vowal village, Gazipur, Bangladesh during January to May 2021 to develop an effective bio-rational based management approach against rose bollworm, Helicoverpa armigera. Six treatments, such as: T₁: Sex pheromone Mass trapping T₂: Sex pheromone Mass trapping + Azadirachtin (Bio-neem plus 1EC) @ 1ml/L of water at 10 days interval; T₃: Sex pheromone Mass trapping + spraying of HNPV @ 0.2 g/L of water at 10 days interval; T₄: Sex pheromone Mass trapping + spraying of Spinosad (success 2.5 SC ) @ 1.2 ml/L of water at 10 days interval; T₅: Farmers practice (spraying of synthetic insecticides, Proclaim 5SG @ 1g/L ) at 7 days interval; T₆: Untreated control were evaluated following RCB design with three replications. The results indicated that T₃ treatment, Sex pheromone Mass trapping + spraying of HNPV @ 0.2 g/L of water at 10 days interval showed the best performance reducing plant and flower infestation and increasing marketable yield followed by T₄ treatment, Sex pheromone Mass trapping + spraying of Spinosad (Success 2.5SC ) @ 1.2 ml/L of water at 10 days interval. In case of maximum marginal benefit cost ratio, T₄ treatment showed best performance.

An experiment was conducted at the research field of the Tuber Crops Research Sub-Center (TCRSC), Bangladesh Agricultural Institute, Munshiganj (BARI), during the potato growing season of 2021–22 with three processing potato varieties viz. BARI Alu-25, BARI Alu-28 and BARI Alu-29. The objective of this experiment was to evaluate three processing potato varieties for growth pattern, dry matter partitioning to the sink and yield performance of processing potato varieties at different days after planting (DAP). Five different harvests were conducted during the growing season to determine dry matter (DM) partitioning to various parts of the plant. The results indicated that 60 days after planting, BARI Alu-28 exhibited the highest tuber dry matter (DM) percentage at 65.98%, suggesting that this variety had reached the end of its vegetative growth phase and was transitioning into the tuber filling stage. In contrast, the other varieties were primarily allocating dry matter to the stems and leaves. A similar trend was observed at 70 and 80 days after planting (DAP). By 90 DAP, the translocation of assimilates to the leaves and stems decreased, with the highest tuber DM recorded at 89.05% in BARI Alu-25. At 100 DAP (the final harvest), BARI Alu-28 was in the senescing stage, while BARI Alu-25 exhibited the maximum total dry weight per plant (241 g). BARI Alu-25 also produced the highest tuber yield at 35.21 t/ha, whereas BARI Alu-28 had the lowest tuber yield at 25.34 t/ha.

The aim of this study is to assess the family burden associated with substance abusers in Bangladesh. A descriptive cross-sectional study was conducted to identify the family burden among 112 participants, selected using a convenient sampling technique. Family burden was measured using a standardized Family Burden Interview Schedule (FBIS) scale. Data were collected through face-to-face interviews and a review of medical records. Descriptive and inferential statistics were used to analyze the data. The majority of participants (85.71%) reported experiencing severe family burden. The total mean family burden score was 1.49 (SD = 0.37) out of a possible 2 points. Significant relationships were found between family burden and several variables: participants’ age (p < .000), education (p < .000), occupation (p < .000), relationship with the patient (p < .000), presence of chronic disease (p < .022), monthly family income (p < .000), the number of hours spent caring for the patient per day (p < .000), patients’ religion (p < .005), education (p < .008), and marital status (p < .034). The findings of this study may contribute to strengthening existing resources and mental health interventions. The new insights gained can help empower family members to better cope with the challenges of caring for a substance-abusing relative, allowing them to manage the burden in a more strategic and effective manner.
