This study aimed to measure the prevailing levels of traffic induced noise pollution at the core academic points and to assess the impacts of noise pollution on students’ health at BAU. The recorded Lave ranges from 55–85 dB. The Lave ranges from 79–85 dB throughout the whole day at FoA and FoAH. The Lave at these two core academic points are almost the double than the permissible limit of 45 dB. The Lmax pressure (96 dB) at Jobber moor during the noon is the maximum inside the whole BAU campus. The movement of traffic vehicles is responsible as the main sources of these noise. The noise level indices and their degree of fluctuation as given by Leq, Lnp, and NC are higher in roadside locations namely at FoA, FoAH, FoAERS. In terms of noise pollution, three of the sampled areas namely FoA, FoAH, and KR market show ‘moderate risk’ (Lave: 81 dB) during the morning whilst, the FoAH possessed the ‘high risk’ with the Lave of 85 dB. The results show that the FoA, FoAH, KR market, Jobber moor, and administration building can be labelled as the highest zone of noise level intensity. Due to excessive noise, university students are facing disorders like irritation, headache, nervousness, insomnia, anxiety, hearing problem, and hypertension. Controlling noise pollution is an absolute necessity for BAU to ensure noise-less academic culture whilst the dwellers of BAU is in the risk of serious noise-related health hazards. The results would be very useful for BAU authority to monitor and formulate a structural noise management policy, and to control excessive noise at our beloved BAU.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84781203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pers.] is a dangerous weed causes great losses in agricultural crops. It is difficult to control due to its reproduction by rhizomes, and its resistance to herbicides. This study aims to evaluate the allelopathic performance of five species of cruciferous plants on germination and some growth indicators of Johnsongrass seeds and rhizomes. Cruciferous species are white cabbage, red cabbage, broccoli, turnip, and garden rocket. The aqueous extracts of all these plants were prepared in 2%, 5%, 10%, and 20% concentrations. Germination inhibition rate, shoot, and radicle length of the seedlings of Johnsongrass were calculated over control environment. The powders of whole cruciferous plants were also analyzed using GC-MS. The results showed that garden rocket had the highest effect on the germination inhibition of both seeds and rhizomes. Garden rocket extracts at 10% and 20% concentrations reduced seeds germination by 100%. On the other hand, rhizomes germination inhibition for 10% and 20% concentrations were found 85.3% and 92.7% respectively. The effects of aqueous extracts of cruciferous plants on shoots and radicals were similar to their effects on the germination of Johnsongrass. The allelopathic effect also increased with increasing concentration of the aqueous extract. The most effective cruciferous plant on the biomarkers of Johnsongrass was garden rocket, while red cabbage was the least. The cruciferous plants, especially garden rocket, have a strong allelopathic effect that can be used as an alternative to herbicides in the control of Johnsongrass.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"217 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74455245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study (in detail) on morphological descriptors of four quinoa genotypes, an experiment was conducted at the Field and Laboratory of Plant Systematics, Department of Crop Botany, Bangladesh Agricultural University during Rabi season (November 2020 to March 2021) following a Randomized Complete Block Design with three replications. A spacing of 25 cm x 10 cm was used. Weeding and irrigation operations were done twice at 20 and 40 days after sowing. Quinoa plants are characterized by the angular stem, red-green, leaf rhomboidal, green, panicle shape intermediate showing both shapes – glomerulate and amarantiform, panicle green at the flowering and became pink at the physiological maturity stages. Plant height and stem diameter were ranged between 60.17-65.65 cm and 4.22-4.58 mm, respectively. The percentage of red and red-green coloured stem, number of teeth leaf–1 and leaf area were significantly influenced by genotypes and ranged between 20.00-46.58%, 53.31-80.00%, 5.60-9.10 and 4.84-6.01 cm2, respectively. Pollen grains are monads, medium in size, 42.99-51.30 µm, polypantoporate, scabrate (microechinate), and exine thickness 2.08-2.40 µm. Panicle length and width, 1000-seed weight and seed yield varied between 31.16-37.23 cm, 3.66-4.37 cm, 3.14-3.43 g and 2.66-3.86 g plant–1, respectively. Among the genotypes, G2 was most productive in the environmental conditions of Mymensingh region. Qualitative morphological traits can be used as markers in the description and characterization of quinoa genotypes. The variation existing among the quinoa genotypes could prove useful in the breeding programs.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84005664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Logistic model and the two stage least square model are applied to identify the factors and effect of mobile money adoption on the saving behavior. The findings reveal that mobile money service adopters have higher degree of propensity to save compared to the non adopters. It also notifies that mobile money service adopter has 2 times higher propensity to save than non adopters. Moreover, rural residents have also higher propensity to save compared to the urban. This study suggests the mobile money services should be properly managed to stable financial inclusion in accordance with income groups, regional and social diversity. This may also helps to reduce the differences among the rural- urban and different income groups also by moving towards achieving sustainable goals.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88026900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern scientific principles and procedures are followed to design and fabricate the baking ovens using low-cost materials. The major drawbacks of this type of traditional oven are: improper control of baking temperature; contamination of products with ashes during heating and excess cost for heating. This study aimed at modeling heat and mass transfer during baking, and evaluating the quality characteristics of bread and cake. The problems were identified by conducting a one-time cross-sectional survey, and the heat and mass transfer were modeled by designing and fabricating an improved oven. This model predicted the bread temperature and moisture content at 160, 170, 180, 190 and 200°C oven temperatures. The result indicated that increasing the oven temperature from 160 to 200°C increased the bread crust temperature from 101.58 to 158.69°C. However, the temperature and weight of bread increased gradually with increasing baking time up to 18-20 min and then started declining until it reached equilibrium after 30 min. The weight loss of bread increased with increasing bread temperature. The model predicted fairly accurate bread temperature and weight loss. It predicted 20 to 132°C against the observed 22 to 115°C during baking at 200°C oven temperature, 0 to 40% weight loss against 0 to 49% observed weight loss. The developed improved oven required 25% less time for baking bread and cake compared to the traditional one. Loaves of bread baked in the improved oven had 27.4% lower moisture content, 660 cm3 higher volume, and 408 g lower crumb firmness value compared to the conventional baking process. The improved baking oven is, therefore, more efficient than traditional baking ovens in terms of heat and mass transfer, baking time and product quality.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85003862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is based on primary data collected in January 2021 from vegetables producers through face-to-face interview method using structured interview schedule. In total 80 commercial farmers (i.e., 40 farmers from each vegetable) were selected purposively from Sadar upazila of Mymensingh district. Tabular and descriptive analyses were used to determine the cost and returns of vegetables cultivation by commercial farmers. Least significant difference (LSD) of multiple comparisons of mean was applied to determine profitable market outlets for cauliflower and cabbage. The study found that both cauliflower and cabbage cultivation were profitable. The per hectare gross costs of cauliflower and cabbage production and marketing by farmers were Tk. 1,93,535 and Tk. 1,95,864, respectively and the corresponding net returns were Tk. 90,329 and Tk. 90,981. Three different market outlets (farm gate, local market, and district market) were found where farmers sold their cauliflower and cabbage. Farmers who sold their cauliflower and cabbage from district market outlet gained maximum net returns, which were Tk.1,31,093 and Tk. 1,07,221, respectively. The results of LSD test established that among the three market outlets, the mean net return earned by selling cauliflower and cabbage to district market is higher than the mean net return earned by selling to farm gate market. Therefore, district market outlet is significantly more profitable outlet for both cauliflower and cabbage. However, most of the farmers chose farm gate market for selling their cabbage and cauliflower because they feel comfortable to sell their vegetables from farm gate area.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82001674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was carried out to develop a socio-economic model for elevating the socio-economic status of poor farmers by rearing Red Chittagong Cattle, a dual-purpose, indigenous cattle. First, a model was developed by a team of Bangladesh Livestock Research Institute which hypothesized that rearing two RCC cattle, one for calf and milk production and another for beef production will enhance the socioeconomic conditions if they are supported with appropriate training and vaccination. A total of 150 farmers were selected from 4 Upazilas and the model was introduced to the farmers and subsequently, the model was implemented. The farmers were provided cattle, training, health care support including regular vaccination, high-yield grass and free fodder-cutting facilities. After the project intervention, the willingness of farmers for cattle rearing for both types that are milk production and beef fattening increased from 20.70% to 22.50%. Moreover, the socio-economic status of the respondents improved significantly. The average annual income of the household increased from 1,03,900 Tk to 1,36,133.15 Tk (31% increase) after the model was applied. Although the family expenditure was lower before implementing this approach, it climbed after the project intervention, along with annual savings. Farmers were more motivated to raise RCC and conserve them in situ as a potential genetic resource when family savings had increased. Considering the benefits of rearing RCC, this model would be suitable for improving the socio-economic conditions of the smallholders and rural farmers of Bangladesh. Moreover, conserving RCC will help in future research on indigenous cattle genetic resources.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73459258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Industries are competing to introduce quality cookies being blended in proportion with wheat or rice flour. Canistel is one of the underutilized fruits available in Sri Lanka. It has potential nutritional value and various health benefits due to the presence of functional compounds in it. Its local abundance prompted the researchers to focus on how it could be incorporated into food products. Therefore, this study was focused on developing flour from canistel fruit and evaluating the possibility of utilizing it as a food ingredient particularly in bakery industry. The canistel chips were dried, powdered, sieved into a fine particle of flour. The prepared flour was added with rice flour as canistel flour: rice flour 75:25, 65:35, 50:50, 35:65, and 25:75, and used as composite flour mixture for the preparation of cookie. The physical, nutritional, and sensory quality properties were evaluated. The data were statistically analyzed with SPSS. The nutritional parameters such as moisture, ash, protein, fat, carbohydrates, and energy were found to be varying between 6.71 to 11.73 %, 1.13 to 2.17 %, 12.97 to 13.76 %, 16.49 to 19.56 %, 52.78 to 62.70 % and 326.66 to 402.63 Kcal/100g, respectively. The physical properties such as density, weight, volume and spread ratio of cookies, showed significant differences (p<0.05) between different treatments. The cookies made with 65:35 percent rice: canistel flour blend received the highest scores for taste, crispiness, and color. Accordingly, the physical, nutritional, and sensory properties of treatment No: T4 with the blend of 65: 35% rice: canistel flour was selected as the best. Therefore, this underutilized fruit could be exploited for the development of new snack varieties with a blend of rice flour that could contribute to the food security of the Sri Lankan people.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85718474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
