Primary data were collected from 60 randomly selected handloom owners. Two main products were considered in this study, i.e., sharee and gamcha . Descriptive statistics and cost-return analysis were performed to assess the present situation and profitability of handloom production. The Gini Coefficient and Lorenz Curve measured inequality among respondents. A log transformed multiple linear regression model was applied to explore the factors influencing handloom products production. Results revealed that most of the handloom weaving was financed through the weavers’ own capital and taking loans from the bank. The undiscounted benefit-cost ratios were 1.12 and 1.20 for sharee and gamcha, respectively, indicating both enterprises were profitable but gamcha was more profitable than sharee. The Gini Coefficient of handloom weavers’ income is less than 0.25. Results from the regression analysis revealed that human labour, yarn, color, and processing cost significantly impacted sharee and gamcha production. Therefore, efficient utilization of these resources in the production process of handloom products would be essential that can bring more profit for handloom production.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84194491","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}

Mohiuddin","doi":"10.5455/jbau.42442","DOIUrl":"https://doi.org/10.5455/jbau.42442","url":null,"abstract":"Potassium (K) is unique among the essential nutrient elements for its diversified role in plant metabolic processes. Potassium improves crop output, protects the crop from diseases and insect-pest infestation, prevents lodging, and reduces the effects of terminal heat stress. Based on this information, it was hypothesized that K will enhance host plant resistance and blast control while increasing yields. A pot experiment was conducted by artificially inoculating Magnaporthe oryzae Triticum (MoT) on a susceptible wheat (Triticum aestivum L.) variety (BARI Gom-26) to determine the effect of soil application of K on blast disease management and the growth and yield. The experiment was carried out in separate plastic pots containing 18kg of virgin soil at the net house of the farm of the Bangladesh Institute of Nuclear Agriculture headquarters, Mymensingh, for two growing seasons of 2018-19 and 2019-20 following a completely randomized design with five treatments and three replications. The dose for soil application were 0, 50, 75, 100 and 125 K kg ha-1, respectively. Disease incidence (%) and severity (%) of wheat blast were evaluated at 11, 13 and 15 days after inoculation (DAI). At 15 DAI, the highest disease incidence (95.45%) was found in absolute control followed by K0 (0 kg K ha−1) (91.98%) and the lowest blast incidence (64.49%) was found in K4 (125kg K ha−1) which was statistically similar with K3 (100kg K ha−1) (70.87%). At 15 DAI, the highest blast severity matrix (90%) was found in absolute control followed by K0 (0 kg K ha−1) (76.02%) and the lowest blast incidence (46.18%) was found in K4 (125kg K ha−1) which was significantly different with others. Among the treatments, 125 kg K ha-1 produced the highest grain yield (26.97 g pot-1) and the lowest (5.79 g pot-1) was found from the absolute control. Flag leaf samples were randomly collected before head emergence from each pot and analyzed in the laboratory for plant nutrient content. The K concentration of flag leaves sample ranged from 1.71% to 5.51% with the average concentration of 3.02%, where the highest K content (%) was recorded in K4 (5.51%) and the lowest was found in absolute control (1.71%). Potassium fertilization appeared to reduce the severity and improve yield of wheat. Correlations suggested that improving dry matter production and K uptakes at the boot stage by K fertilization can reduce severity later in the growing season and increase wheat grain yield. It can be concluded that high K concentration on leaf tissue was important to decrease wheat blast symptom.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82849838","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 chlorophyll content is related to nitrogen content means the amount of fertilizer of a crop. Therefore, determining SPAD value is directly involved with crop health. Minolta SPAD meter can directly measure this value, and this is a well-established method in the research field for measuring chlorophyll content. Still, this instrument is too costly, which is beyond a farmers’ reach in the perspective of Bangladesh. The purpose of this study is to predict the SPAD value for paddy leaves using the smartphone-based direct contact imaging method to estimate the chlorophyll content of a paddy leaf. Numerous features were extracted from each image to predict the SPAD values. The features were then used as parameters in the multiple linear regression model. The models' performance was evaluated using images captured from a paddy field using a Minolta SPAD-502 Chlorophyll Meter. The multiple linear regression model's R2 and root mean square error (RMSE) values were 0.71 and 3.6512, respectively. Therefore, this result confirms that the direct digital contact imaging method has the potential to quantify the SPAD value of paddy leaves accurately. However, these results could be more accurate if the image acquisition was made from the seedling to mature stage of the paddy. In the future, an android app will be developed using this value which can directly measure the chlorophyll content of paddy leaves.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83820252","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}

As a non-climacteric fruit, proper postharvest management is vital for dragon fruits in the context of decreasing postharvest losses and extending shelf life. A factorial experiment consisting of three locations (Tala, Dumuria, Keshobpur), and three precooling systems (without cooling, hydro cooling, CoolBot-AC cooling) was conducted to evaluate physico-chemical quality attributes of dragon fruits. The results showed that physico-chemical quality attributes were significantly influenced by precooling systems in which the CoolBot-AC cooling system significantly reduced weight loss by more than 9 % and extended shelf life by more than 2.5 days. Of the three-precooling system, the CoolBot-AC system significantly performed better resulting in higher flesh weight, flesh and pericarp ratio, edible portion, moisture, and dry matter content over other precooling systems. Similarly, CoolBot-AC precooling system performed pointedly better than other precooling systems and retained acceptable skin colour, firmness, high levels of TSS content, 12.03 % more anthocyanins, 30.73 % more flavonoid, 32.55 % more total phenols, 24.22 % more carotenoid, and high levels of ascorbic acid content. No statistical variation was documented among locations with a few exceptions. Therefore, the results indicated that CoolBot-AC precooling system could be an effective postharvest management strategy for prolonging shelf life and reducing postharvest losses of dragon fruit.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74974614","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}

This study was conducted to evaluate a solar tunnel dryer for drying cabbage in comparison to traditional open sun drying at the advanced drying lab of the Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh. Salt pre-treated cabbage was used for drying inside the dryer and open sun drying. The parameters like solar radiation, temperature, relative humidity, and moisture content were measured using standard instruments during the experiments. The results showed that the maximum peak temperature inside the drying chamber was 45 °C during mid-day (12 pm) when solar radiation was 600 w/m2 and in an average inside temperature was approximately 30°C to 40°C in a full sunny day (9:00 AM to 04:00 PM) when average solar radiation was 321±115 W/m2. The moisture content of sliced cabbage was reduced initially 94.42, 90.18, and 92.24 % (w.b.) to 4.85, 15.84, and 15.71% (w.b.), and drying time of the dryer was 28, 21, and 19 hours in 1st, 2nd, and 3rd trials, respectively. The drying rate and drying efficiency were found 0.15 kg/hr. and 8.22 %, respectively in tunnel dryer and 0.02 kg/hr. and 3.38 %, respectively in open sun drying. The color and texture of the solar tunnel dried cabbage were better than the open sun drying method.

Twenty (20) apparently healthy cockerels were randomly selected and equally distributed into two groups: Group I (control group) and Group II (experimental group). The cockerels in both groups were carefully reared and provided with formulated feed during the research. For Group II, the 8-week-old birds were caponized, and further the capons were slaughtered at 16 weeks of age for conducting this study. In both groups, daily feed intake (g) and body weight (kg) of the cockerels were recorded at 8, 10, 12, 14 and 16 weeks of age, while the comb height (mm) of the birds were recorded at 8, 12 and 16 weeks of age; and the weight (g) of leg, breast, liver, spleen and adrenal gland were recorded at only 16 weeks of age. The body weight, daily feed intake, and weight of leg, breast, liver, spleen and adrenal gland were significantly (P<0.05) increased mostly at 14-16 weeks of age in Group II. On the contrary, the comb heights were significantly (P<0.05) decreased at 12-16 weeks of age in Group II than Group I.

The fresh brinjal and tamarind pulp were analyzed for nutritional composition. Developed brinjal pickles incorporation with tamarind pulp were analyzed for nutritional composition, sensory attributes, microbiological status, and overall storage stability. The nutritional compositions of developed pickles were different depending on the processing ingredients. Chemical analysis of developed pickles showed that the highest moisture content (60.23%) was given by sample A (500 g Brinjal + No tamarind pulp) followed by Sample B (450 g Brinjal + 50 g tamarind pulp), C (400 g Brinjal + 100 g tamarind pulp), and D(350 g Brinjal + 150 g tamarind pulp). Other components such as ash, protein, fat, fibre, vitamin C, magnesium, phosphorus, iron & total carbohydrate content increased with an increasing amount of tamarind pulp with brinjal. The acceptability of prepared pickles was organoleptically evaluated by the panelists using 1-9 hedonic scale. Sensory properties more specifically overall acceptability were in a rank like sample D>C>B>A. Storage studies were carried out for up to 4 months at room temperature (29°-30° C) at interval of one month. Microbial load decreased with the increasing amount of tamarind pulp, salt, sugar, and mustard oil in brinjal pickles. It could be due to the antimicrobial activity of tamarind pulp, salt, sugar, and mustard oil. The color, flavor & texture were unchanged up to 4 months of storage except slightly spoiled in samples A and B at 4th month.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87549960","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}
