Adherence of people to the guidelines and measures suggested in fighting the ongoing COVID-19 pandemic is partly determined by the Knowledge, Attitude, and Practices (KAP) of the population. In this cross-sectional study, we primarily addressed two key issues. First, we tried to determine whether there is a significant difference in the estimated COVID-19 knowledge level from the online and phone survey methods. Second, we tried to quantify the knowledge and attitude of COVID-19 in Bangladeshi adult population. Data were collected through phone calls (April 14-23, 2020) and online survey (April 18-19, 2020) in Bangladesh. The questionnaire had 20 knowledge questions with each correct response getting one point and incorrect/do not know response getting no point (maximum total knowledge score 20). Participants scoring >17 were categorized as having good knowledge. The percentages of good knowledge holders were 57.6%, 75.1%, and 95.8% in the phone (n=1426), online non-medical (n=1097), and online medical participants (n=382), respectively. Comparison between phone and online survey showed that, overall, online survey might overestimate knowledge level than that of phone survey, although there was no difference for elderly, poor, and rural people. Male gender, higher education, living in town/urban areas, good financial condition, and use of internet were positively associated with good knowledge. However, higher knowledge was associated with having less confidence in the final control of COVID-19. Our adult population-level estimates showed that only 32.6% (95% CI 30.1-35.2%) had good knowledge. This study provides crucial information that could be useful for the researchers and policymakers to develop effective strategies.
An experiment was conducted in research fields under the Department of Genetics and Plant Breeding of Bangabandhu Sheikh Mujibur Rahman Agricultural University in Bangladesh to study Phenotypic and genotypic correlation coefficient of quantitative characters and character association of aromatic rice. Forty-one aromatic rice germplasm of diverse sources were used to assess the character association and contribution of characters towards grain yield. Path coefficient analyses were carried out for selected genotypes and to find out the direct and indirect effect of component characters on grain yield. Analysis of phenotypic and genotypic correlation coefficient of quantitative characters and partitioning of genotypic correlation to grain revealed that the correlation coefficients of grain yield per hill with 1000-grain weight and harvest index were positive and highly significant. Spikelet sterility showed highly significant negative correlation with grain yield at genotypic level only. The parameter 1000-grain weight showed the highest positive direct effect on grain yield. Panicle length and spikelet sterility showed negative negligible direct effect. The highest positive indirect effect was observed for 1000-grain weight via plant height and the highest negative indirect effect for 1000-grain weight via number of filled grains per panicle. Data of this study might be useful for quantitative assessment of the variation in yield and yield components, their interrelationship, and direct and indirect effects of different characters on grain yield of aromatic rice.
An in vitro experiment was conducted to find out the optimum hormonal supplement and sucrose level for the bulb production of Hippeastrum. Murashige and Skoog medium supplemented with different hormone concentrations of BAP (0.0, 2.0, 4.0, 6.0 and 8.0 mg/L) and CCC (0.0, 125, 250 and 500 mg/L) and sucrose levels (30, 60, 80, 90 and 110 g/L) were used in this study. Sucrose level at 90 g/L produced the maximum average weight as well as the highest regeneration percentage. The increasing rate of CCC increased the number and average weight of bulb. The maximum bulb formation observed in media supplement with 6.0 mg/L BAP and 500 mg/L CCC fortified with 90 g/L sucrose.
This study investigated the knowledge and attitudes towards COVID-19 in Bangladeshi adults by online and phone survey methods during the early stage of its spread.Methods: Data were collected through phone calls (April 14-23, 2020) and online survey (April 18-19, 2020) in Bangladesh. The questionnaire had 20 knowledge questions with each correct response getting one point and incorrect/don't know response getting no point (maximum total knowledge score 20). Participants scoring >17 were categorized as having good knowledge. Results:The percentages of good knowledge holders were 57.6%, 75.1%, and 95.8% in the phone, online non-medical, and online medical participants, respectively. Most of the phone and online participants had good knowledge of the preventive practices of COVID-19. However, among the non-medical participants (both phone and online), the correct response rates were lower than 80% for the knowledge questions asking about the facts that -some patients may have no symptoms, diarrhea is a symptom of this disease and that it cannot be prevented by any currently available medication. Male gender, higher education, living in town/urban areas, good financial condition, and use of internet were positively associated with higher knowledge score among the non-medical participants. However, higher knowledge score was associated with having less confidence in the final control of COVID-19. Conclusion:Our study identified some COVID-19 information that were less known among the participants and the potential factors that were associated with having good versus poor knowledge. Besides, this study sheds light on the attitude of Bangladeshi adults towards COVID-19.
An experiment was conducted in the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to investigate the effect of foliar application of Miyodo on morphology, yield contributing characters and yield of T. aman rice cv. BR-11. The concentrations of Miyodo used were 2 mgL-1, 3 mgL-1, 4 mgL-1 and 5mgL-1 with a control. The experiment was laid out in a randomized complete block design with three replications. Application of Miyodo by spraying at 45 days after transplanting significantly enhanced plant height, number of tillers and effective tillers, number of leaves and leaf area, size of flag leaf, total dry matter, panicle length, number of total grains and filled grains, 1000-grain weight, grain yield, straw yield, and harvest index. The result showed that the application of 5 mgL-1 Miyodo produced the highest grain yield of BR-11 compared to other concentrations as well as control. However, further study is needed to determine the higher concentration limit of Miyodo in maximizing the growth and yield of T. aman rice cv. BR-11.DOI: http://dx.doi.org/10.3329/pa.v19i1.17106 Progress. Agric. 19(1): 45 - 49, 2008
