Assessment of land dynamics transformation into tea plantations using support vector machine

Precisely monitoring land use dynamics and spatial distributions is essential for sustainable development and long-term land management. Tea is one of the leading beverage crops cultivated in Bangladesh, expanding rapidly in northern districts and forcing land use change. This study aims to decipher the expansion of tea cultivation and land dynamics transformation to tea land areas in the northern region of Bangladesh by using Landsat 5 TM and Landsat 8 OLI/TIRS surface reflectance images. The supervised support vector machine (SVM) method was used for classification purposes, resulting in three classified maps for the years 2004, 2013 and 2022, having overall accuracies of 91.43 %, 98.67 %, and 98.48 % and kappa coefficients of 89.51, 98.37, and 98.13, respectively. The images were classified into six land use classes: agriculture, tea cultivation area, settlement, waterbody, bare land, and forest. Land transformation results reveal that overall tea land increased by 41.08 % from 2004 to 2022, experiencing a downward trend during 2004–2013, while from 2013 to 2022, a dramatic rise of 70.01 % (equal to 4683.60 ha) tea cultivation area was found in Panchagarh district. The bare land was among the most highly transformed land classes into tea plantations, followed by the forest area. This study provides evidence of transforming underutilized land class into a profitable land use practice, i.e., tea plantation. Thus, cutting-edge technologies would be imperative in land transformation detection for sustainable land management and policy implications for the sustainable development of small landholding livelihoods and the tea industry.

Effect of stocking density on growth performance, survival and production of Monosex Tilapia (Oreochromis niloticus) under nursery ponds in northern regions of Bangladesh

The present study was to assess and evaluate the culture potential of Tengra with short-cycle species in the seasonal water bodies of farmers’ fields and disseminate the cultural technologies in a different part of the country. The research study was evaluating the improvement of nursery management technique in drought prone area of Northern region in farmer field level. Before conducting research fish farmers of Different upazila were selected by departmental authority and pre training management. Growth, survival and production performances of Oreochromis niloticus fingerlings were evaluated for 40 days in nine nursery ponds having an area of 20 decimal each with an average depth of 1.0 m. Three stocking densities such as 1000 dec-1 (T1=Treatment-1), 1200 dec-1 (T2= Treatment-2) and 1400 dec-1 (T3=Treatment-3) were tested with three replications. Fry were fed with commercial nursery feed (30% crude protein). The rate of feeding was 25% to 8% of the estimated body weight of fry. The physico-chemical and biological parameters of pond water were within the suitable range for fish culture. Growth in terms of final weight, final length, weight gain, length gain and specific growth rate was significantly higher in T1 than those obtained from T2 and T3. The survival of fish fingerlings was higher in T1(85.67%) than T3 (76%) and T2 (83%) respectively. Maximum of fingerlings was produced in T2 than those in T1 and T3. Among the treatments evaluated, 1000 dec-1 was the best stocking density considering the growth performance of the fingerlings of monosex Tilapia, O. niloticus in nursery ponds.

Assessment of knowledge, attitudes, and practices on vaccine usage among small ruminant farmers in the Northern Region of Bangladesh.

Small ruminants require vaccines to prevent and manage diseases. Unfortunately, no studies have been conducted in Bangladesh to assess the knowledge, attitudes, and practices (KAP) of small ruminant farmers (SRF) regarding vaccine use against infectious diseases, affecting the success of vaccination campaigns. The present study aims to assess SRF's KAP regarding vaccines, revealing gaps and barriers to efficient vaccination. Two hundred and twenty-eight SRF in northern Bangladesh were surveyed in a cross-sectional study. Data were collected from random participants through face-to-face interviews using a structured questionnaire. KAP levels were categorized as "good" or "poor" and "positive" or "negative" using a scoring method with a 60% cutoff. The analysis comprised the utilization of descriptive statistics as well as logistic regression models. Results showed that most participants were female (60.5%), aged 31-40 (34.2%), with secondary education (28.1%), and vaccination training (22.8%). While 75% knew about vaccines, only 37.3% understood their role in preventing infectious diseases, and 63.6% in reducing antibiotic use 68.4% of farmers were aware of negative drawbacks, and 61.8% reported vaccinating their herds. About 42.1% of the farmers had good knowledge, 52.6% had a positive attitude, and 22.8% followed good practices. Female farmers with graduate degrees and 6-10 years of goat farming experience, but not those with vaccination training, demonstrated stronger knowledge. Female farmers with a graduate degree and 6-10 years of goat farming experience displayed positive attitudes. Female goat farmers from Thakurgaon had a higher likelihood of following good vaccination practices than those with vaccination training. The study unearths disparities in KAP scores among farmers. To effectively address KAP gaps concerning vaccine usage and prevent potential infectious diseases, it is essential to design focused educational and training programs. About 52.6% of SRF hold a positive view toward vaccines.

Trait analysis of short duration boro rice (Oryza sativa L.) varieties in northern region of Bangladesh: Insights from heatmap, correlation and PCA

The role of genetic variation is utmost importance in the selection of a desirable genotype for breeding programs. In the northern region of Bangladesh, the performance of five short duration boro rice varieties (BRRI dhan28, BRRI dhan74, BRRI dhan81, BRRI dhan88, and Bangabandhu dhan100) on yield and yield-contributing traits were evaluated in four locations. Yield attributes tiller hill-1 (TN), panicle hill-1 (PN), filled grain panicle-1 (FG), panicle length (PL), 1000-grain weight (TGW), and harvest index (HI), showed a positive correlation with grain yield (GY). Conversely, spikelet sterility (SSP) and unfilled grains panicle-1 (UFG) showed negative associations with grain yield. Principal component analysis (PCA) revealed that the first three components accounted for 89.60% of variability. The highest positive eigenvalue was observed in DF, DM, BY, HI, PN, SY, TN, PL and GY in PC1, indicating their significant influence on the overall genotype variations. PC2 was primarily driven by plant height (PH) and FG, while PC3 driven by TGW and UFG. The results suggest that grain yield is highly influenced by FG, PH, DM, DF, PN, TN, PL, TGW, SY, BY, and HI. These components highlighted the importance in distinguishing rice genotypes with higher grain yield potential. By considering these traits, BRRI dhan74 have outperformed other varieties, followed by BRRI dhan88 and Bangabandhu dhan100. BRRI dhan74 is most suitable for all four location followed by BRRI dhan88. The traits such as PN, PL, FG, TGW, PH, & HI significantly influence rice yield and should be prioritized in breeding programs aimed at developing high-yielding rice varieties.

Prevalence, Causes, and Management Strategies of Fungal Diseases in Northern Regions of Bangladesh

In Bangladesh, fungus-related skin diseases are highly prevalent. Until this result began, there was no research in Bangladesh to find the cause and management strategies for fungal infection, but there is still no complete research on it. This survey aimed to evaluate the incidence, etiology, and therapeutic alternatives for various fungal ailments in Bangladesh. The research was carried out in Rajshahi from January to June 2019 by the Pharmacy Department of Varendra University. A compilation of 489 patient data was obtained throughout the investigation using a semi-structured questionnaire. The participants' ages vary from three months to seventy years; 327 are male, and 162 are female. The most prevalent skin conditions among the patients are as follows: ringworm (11.25%), skin infections affecting the ear, nose, fingers, and uterus (11.04%), acne (8.19%), allergy (9.82%), dandruff (5.11%), dermatitis (9.00%), eczema (5.73%), and scabies (7.18%). Student individuals comprise 49.28% of the patients, day workers 16.56%, housewives 16.36%, and employed 14.31%. Patients are housed in 53.17 percent concrete houses, 26.5 percent huts, and 26.18% semi-structures. Patients wash their clothing with tap water at a rate of 52%, followed by tube well water at 21.27%, pond water at 20.45%, and river water at 5.52%. It is evident from this study that fungal diseases affect individuals of all ages, including men and women. An adverse finding of the research was that over forty percent of patients do not receive accurate instructions from their physicians, which raises the risk of drug resistance and further contamination.

Optimization of green microwave-assisted extraction of essential oil from lemon (Citrus limon) leaves: Bioactive, antioxidant and antimicrobial potential

This research delves into the analysis of essential oil derived from Citrus limon leaves cultivated in the northern region of Bangladesh, focusing on their potential attributes. The essential oil was extracted employing a microwave-assisted gravity station without using solvent. Optimization was carried out in terms of time, temperature and power as a function of oil yield. The study revealed the highest oil yield of 2.5 % after 50 min at 110 °C, maintaining a microwave power of 300 watt. Twenty-four (24) phyto-components were identified by Gas Chromatogram- Mass Spectrometer (GC-MS) where d-Limonene (34.10660 %) was dominant compound. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was used to assess the antioxidant activity of essential oil. Notably, essential oil displayed superior DPPH radical scavenging activity (IC50 8.57 ppm) compared to butylated hydroxytoluene (BHT) (IC50 10.63 ppm), a common antioxidant standard. Furthermore, a variety of harmful microorganisms were used to evaluate the antimicrobial efficacy. The extracted essential oil exhibited the strongest antimicrobial effectiveness against bacteria Staphylococcus aureus (ZOI-27.50 mm, MIC-7.8 μL/mL) and the fungi Candida albicans (ZOI-32.83 mm, MIC-1.95 μL/mL). These findings demonstrate the Citrus limon leaves essential oil contains bioactive components with strong antioxidant and antimicrobial properties. The extracted essential oil holds significant potential for applications in the foods, pharmaceuticals and cosmetic industries.

Background: The mental foramen is an important anatomical landmarks during surgical intervention and anaesthetic nerve block procedure involving inferior alveolar nerve and mental nerve. Objectives: The aim of this study was to determine the variation of position of mental foramen in relation to side and sex. Methods: This cross-sectional type of descriptive study was conducted over a period of 1 year from January 2021 to December 2021 in the Department of Anatomy, Rajshahi Medical College, Rajshahi. This study was performed on 250 dry adult human mandibles (148 were male and 102 were female mandibles) which were collected from the students of Department of Anatomy, Rajshahi Medical College, Rajshahi as well as other Medical Colleges after fulfilling the inclusion criteria. Data were collected purposively with the help of a semi-structured questionnaire. All the measurements were performed using digital sliding Vernier calipers and the data were analyzed via SPSS software, version 24.0. Statistical significance was evaluated as appropriate probability level p < 0.05 for all tests. Results: The study revealed that 96% of mental foramens were oval in shape. Out of six morphometric parameters of mental foramen, four parameters (Distance from alveolar crest to upper margin, distance from lower border of mandible to lower margin, distance from symphysis menti to medial margin and horizontal diameter of mental foramen) were not statistically significant (p > 0.05) but distance from posterior border of ramus of mandible to lateral margin and vertical diameter of mental foramen were statistically significant (p < 0.001). Horizontal diameter of mental foramen of right halves and vertical diameter of mental foramen of both halves were higher in male than female and these were statistically significant (p < 0.05). But horizontal diameter of mental foramen of left halves between male and female was statistically non-significant (p > 0.05). Conclusion: This study might help us in establishing a reference data-base in our country for the Anatomists in general, Dental Surgeons and Maxillofacial Surgeons. TAJ 2023; 36: No-2: 193-200

Forecast skill of Bangladesh summer monsoon rainfall in C3S and NMME models after calibration

This study assesses the dynamical seasonal predictions initialized in April and May for forecasting Bangladesh summer (June to September: JJAS) monsoon rainfall (BSMR) over the 1993–2016 period. The BSMR from nine models, sourced from the North American Multi-Model Ensemble (NMME) and the Copernicus Climate Change Service (C3S), undergoes a calibration process. This calibration employs the Canonical Correlation Analysis (CCA) technique to rectify biases within each individual model's ensemble mean BSMR data (referred as predictor or X variable). These corrections are made in comparison to observed BSMR (referred as predictand or Y variable), acquired from the Climate Hazards Group InfraRed Precipitation with Station data. Subsequently, the models that undergo calibration are amalgamated to construct a calibrated multi-model ensemble (CMME), which, in turn, facilitates the generation of a forecast for BSMR. The CCA correction brings about a significant improvement in root-mean-square error, underscoring the presence of correctable systematic biases in the raw model forecasts. However, these CCA corrections weakly enhance the skill (anomaly correlation) across the region. The scores that assess discrimination (the two-alternative forced-choice: 2AFC and the area under the relative operating characteristic curve: ROC for above/below normal BSMR) for tercile-based forecasts exceeded 50 % across a substantial portion of the region. This indicates a superior level of discrimination compared to what one would anticipate based on climatology. Using the CMME approach, a probabilistic forecast for the 2022 BSMR was generated and proved quite effective in capturing the observed 2022 BSMR tercile, which includes below-normal and above-normal categories of rainfall in the central-southern and northern regions of Bangladesh respectively. Furthermore, the absence of substantial skill improvements may be attributed to inaccuracies in the teleconnection patterns of the simulated first leading principal component (PC) time series of BSMR with the El Niño Southern Oscillation. In contrast, the second PC time series exhibits a similar connection to observations. These findings emphasize the importance and utility of statistical post-processing in producing reliable seasonal climate outlooks for the region.

Amino acids profile of six freshwater Algae in the northern region of Bangladesh: A solution for the protein supplement of poultry feed

Algae is an important natural source of protein, specifically amino acid source, which are the building blocks of enzymes, hormones, nucleic acids, etc. Herein, the amino acid composition was investigated in six commonly growing fresh-water algae. The number of amino acids in Oscillatoria brevis, Spirulina platensis, Pithophora kewensis, Euglena viridis, Hydrodictyon reticulatum, and Aphanocapsa holsatica were detected 15, 12, 17, 15, 14, and 15, respectively. Among studied algal species, the amino acids: proline (29239.3 ± 276.4 μg/g), histidine (10056.8 ± 85.4 μg/g), aspartic (3030.6 ± 48.6 μg/g), threonine (1492.3 ± 31.8 μg/g) were detected in the highest amount in O. brevis, S. platensis, P. kewensis, A. holsatica, respectively. It is reported that the range of the ratio between 50/50 to 60/40 of essential amino acid/(nonessential amino acid + conditional essential amino acid) promotes maximum growth performance and best energy utilization. The obtained results of this study suggested that a combination of A. holsatica, H. reticulatum, and O. brevis can provide a good ratio (48/52) of amino acids and the noble source of essential amino acids for feed or food supplements, especially for poultry's stamina and, consequently, welfare.

Some aspects of reproductive biology of gangetic ailia, \(\textit{Ailia coila}\) (Hamilton, 1822) in Bangladesh

The present study was conducted by Bangladesh Fisheries Research Institute, Floodplain Sub-station to investigate the reproductive biology of Ailia coila in the northern region of Bangladesh. A total number of 100 fish samples were collected on a monthly basis from the Atrai River and Jamuna River during the period from January 2022 to December 2022. The highest mean value of the gonado-somatic index (GSI) was recorded in July (8.78 ± 1.95%), whereas the lowest was found in December (0.15 ± 0.09%). The highest individual fecundity (2,450 ± 570) and ova diameter (0.38 ± 0.07 mm) was also observed in July. From the histological observation of the ovary, the highest percentages (75%) of mature oocytes were observed during the month of July. Based on the GSI, fecundity and gonadal histology, the breeding season of A. coila was observed from June to August with a remarkable peak in July. In the case of length weight relationship (LWR), the coefficient of determination value (r2) was found 0.96 and the slope was found b = 1.50 which indicated the pattern of negative allometric growth of this species as b < 3. In contrast, an increase was recorded in the fecundity associated with the rise of total length, body weight and gonad weight showed a significant linear relationship. This study would assist in the development of induced breeding techniques and provide valuable information for the sustainable management of this population in the inland open ecosystem.

Factors driving the adoption of organic tea farming in the northern region of Bangladesh

Tea is a regular export item for Bangladesh, but due to slow growth in production, the country's tea exports have declined. However, organic tea has a great future in this regard. Exploring the underlying factors for the adoption of organic tea farming has great potential for the development of tea production in a sustainable manner. Therefore, our main objective was to identify factors influencing tea growers’ attitudes, perceptions, and adoption of organic tea farming in the Panchagarh district of Bangladesh. We adopted the Theory of Planned Behavior (TPB) to investigate the underlying factors affecting the farmers' belief in the adoption of organic farming were measured based on control factors (marketing factors and cost and benefit factors), attitude towards organic farming, and social factors (extension factors) through a binary logistic regression model. Results of this study revealed that organic growers had a more favorable perception, which was significantly different from non-organic growers reading of various factors related to organic farming. Our results demonstrated that education and knowledge significantly influence the farmers to form a highly favorable attitude towards organic tea farming, which together explained 20.6 percent (R2 = 0.206) of the overall variance. Moreover, attitudes towards organic farming and cost-benefit (CBF) factors had a significant impact on the adoption of organic tea farming. Results also revealed that the predicted adoption probability was found to be higher among those farmers who had a highly favorable attitude and a high perceived CBF level towards organic farming. Finally, based on the findings, we concluded that a participatory extension program to enhance the level of knowledge related to organic tea farming could significantly impact farmers’ attitudes and behaviors towards the practice of organic tea farming.

Organoleptic and Biochemical Analysis of Traditional and Customized Product of Shidhils

A detailed survey was conducted to collect information on the present status of traditional preparation procedure of Shidhil at the Northern region of Bangladesh. A total of 10 samples of traditionally prepared Shidhil was collected from Rangpur, Kurigram and Nilphamari districts and brought to the Department of Fisheries Technology in zipper polythene packets. Proximate composition of the traditionally prepared Shidhil showed that, percent moisture content in Rangpur samples was higher than other samples whereas the percent protein found higher in kurigram samples. Customized product of improved Shidhils were prepared in the same laboratory with kachki (Corica soborna), mola (Amblypharyngodon mola), punti (Puntius ticto) and mixture of these three species of fishes. The survey on traditional preparation procedure of Shidhil revealed that the traditional preparation procedure of Shidhil is quite similar among the districts though there were some differences in shape and weight. Variations were observed in the price of Shidhils per piece and it ranged from 10 to 40 taka/piece. No wholesaler could be found in the marketing channel of Shidhil and it is prepared mostly for home consumption. The biochemical study of the improved Shidhils showed that the percent mean value of moisture, protein lipid and ash of dried fishes obtained at the initial stage changed while Shidhil was prepared using these dry fishes. In the case of kachki fish percent moisture content increased from were 16.12 to 23.84. The percent mean value of protein of dried punti fish were 51.48 which decreased to 41.07% after preparing Shidhil. On the other hand, the percent lipid value was 15.08 for dried mola which increased to 24.25 in mola Shidhil. In the case of mixture of three species of these fishes the percent mean value of ash was 12.73 which decreased 10.38 after preparing Shidhil.

MATERNAL NUTRITIONAL KNOWLEDGE AND DETERMINANTS OF THE CHILD NUTRITIONAL STATUS IN THE NORTHERN REGION OF BANGLADESH

This present study investigates the factors that affect child nutrition and the status of maternal Knowledge in the northern region of Bangladesh. For this purpose, this study employs a cross-sectional data survey of two divisions in the northern region of Bangladesh, namely Rangpur and Rajshahi, from which three districts were chosen from each division using a simple random sampling process. This survey collected data from 527 respondents with face-to-face direct interview method. The questionnaire is in the native language for their understanding. This study applies Weight for Age, Height for Age, Weight for Height, and Weight for Height for the nutritional status of children. This study uses bivariate logistic analysis for factor analysis and descriptive analysis for mothers' nutritional Knowledge. The result shows that sanitation, mothers' Employment, maternal nutritional Knowledge, wealth index, maternal educational status, and antenatal care are the key significant determinants of child nutritional status. In addition, this study also reveals that only 30% of the total respondents were aware of the child's nutritional status while feeding their children, that is 158 out of 537 mothers. The findings of this study indicate that improvement in the rate of a child's dietary diversity, women's dietary diversity, and also self-esteem leads to an improvement in the child's nutritional status in a significant manner. It also indicates that moving towards an upward ceiling for cases including compulsory higher education for women, spreading awareness about child nutritional issues, and prohibiting child marriage and early premature pregnancy may enhance sustaining lives for them.

Evaluation of transfer factors of 226Ra, 232Th, and 40K radionuclides from soil to grass and mango in the northern region of Bangladesh

Bangladesh is a rapidly developing country, which is vulnerable to various types of pollution due to the large-scale industrial and associated human activities that might potentially affect the locally harvested foodstuffs. Therefore, the transfer factor is an essential tool to assess the safety of foodstuffs due to the presence of natural radioactivity in environmental matrix and/or strata. This is a first study of its kind conducted in a well-known region for mango farming in Bangladesh, measuring the uptake of naturally occurring radioactive materials (NORMs) by grass and mango from soil to assess the ingestion doses to humans. The HPGe gamma-ray detector was used to determine the concentrations of NORMs in samples of soil (20), grass (10), and mango (10), which were then used to calculate the transfer factors of soil to grass and soil to mango. Average activity concentrations of 226Ra, 232Th, and 40K in associated soil samples (47.27 ± 4.10, 64.49 ± 4.32, 421.60 ± 28.85) of mango and 226Ra and 232Th in associated soil samples (45.07 ± 3.93, 52.17 ± 3.95) of grass were found to exceed the world average values. The average transfer factors (TFs) for mango were obtained in the order of 40K(0.80) > 226Ra (0.61) > 232Th (0.31), and for grass, it shows the order of 40K (0.78) > 232Th (0.64) > 226Ra (0.56). However, a few values (3 mango samples and 3 grass samples) of the estimated TFs exceeded the recommended limits. Moreover, Bangladesh lacks the transfer factors for most of the food crops; therefore, calculation of TFs in the major agricultural products is required all over Bangladesh, especially the foodstuffs produced near the Rooppur Nuclear Power Plant, which is scheduled to be commissioned in 2023.
