Published: December 2022

A field experiment was conducted to estimate genetic variability, heritability and correlation among the economically important characters in gladiolus varieties at the Instructional Farm, College of Horticulture, BUAT, Banda. The healthy and uniform sized corms (4 to 5 cm) were planted at a spacing of 30 × 20 cm in each row at a depth of 5-6 cm. Before planting, corms were dipped in captan (0.2%) solution for 25-30 min as a preventive measure against Fusarium wilt disease. The varieties showed significant variability (p < 0.05) for days taken to spike emergence (66.67-86.69 days), days taken to opening of first floret (86.21-101.80 days), plant height (74.93 to 105.47 cm), spike length (67.07 to 89.93 cm), rachis length (33.89 to 55.64 cm), water uptake (17.33-46.67 ml), corm weight (39.97 to 100 g) and number of cormels per plant (4.47-41.97). Phenotypic coefficient of variation and genotypic coefficient of variation were high for the traits studied, except days taken to spike emergence, days taken to opening of first floret and corm diameter. High broadsense heritability value was found for number of corms per plant (90.64 %), corm weight (76.09 %) and days taken to opening of first floret, indicating the presence of additive gene effects. Positive correlation was found between days taken to spike emergence and days taken to opening of first floret (r = 0.880**); number of leaves per plant (r = 0.543*), plant height (r = 0.560*) and corm weight (r = 0.515*).

Published: December 2022

The genetic variability and character association among important yield and attributing traits was studied in 20 genotypes of tomato. The magnus of the phenotypic coefficient of variation (PCV) for all characteristics was higher than the magnitude of the genotypic coefficient of variation (GCV). High PCV, GCV, and heritability accompanied by high genetic advance as per cent of mean was recorded for the number of fruits per plant, average fruit weight, number of flower clusters/plant, number of fruits per cluster, plant height, number of flowers per cluster and locule number, polar diameter, equatorial diameter, pericarp thickness, fruit yield/plant. Therefore, selection in early generations would be effective in the improvement of these traits. The trait inter-relationship studies revealed that for aiming at high-yielding tomato genotypes, selection based on average fruit weight, number of fruits per plant, polar and equatorial diameter, plant height, number of primary branches, days to 50% flowering, and days to the first harvest would be effective.

Published: December 2022

Ginger (Zingiber officinale Rose) is one of the important spice crops grown organically in the hill zone of West Bengal. Among the various diseases that cause constrains to the organic ginger production Ralstonia solanacearum causes serious threats to the ginger growers. An experiment was conducted to study the influence of different intercropping patterns on yield, population dynamics, and disease incidence of R. solanacearumin ginger crop under organic management practice. Observation on population dynamics of R. solanacearum under different intercropping patterns revealed that the marigold when intercropped with ginger had a maximum influence on population build-up during 2019 and 2020. Also, it has the potentialities to reduce the population load thereby reducing the disease incidence and increasing the rhizome yield. Therefore, marigold can be incorporated as an intercrop in organic ginger cultivation for reducing the bacterial wilt disease.

Published: December 2022

Background: The association between long-term use of metformin and low vitamin B12 levels in patients with type 2 diabetes mellitus (T2DM) has been proven. However, the prevalence among metformin induced vitamin B12 deficiency in T2DM patients showed considerable variations among the studies. The potential of deficiency to cause new onset or worse preexisting peripheral neuropathy in T2DM patients has been investigated with conflicting results.The objective of this study is to determine the frequency of vitamin B12 deficiency among patients with T2DM patients on metformin therapy compared to those who are not taking metformin.
Methods: This crosssectional analytical study was conducted at the Department of Medicine, in Sylhet M. A. G. Osmani Medical College &Hospital, Sylhet. Total 100 patients’ withT2DM were selected according to inclusion and exclusion criteria following informed written consent. They were divided into two groups; each groups contains 50 patients. Group-I included patients who were taking metformin for e”1 year and Group-II included patients who were not taking metformin for at least 1 year. Detailed history taking, proper clinical examinations and relevant investigations were done. After collection of all the required data, final analysis was carried out by using the SPSS version 22.0.
Results: Among 100 patients of T2DM, mean age were 55.4±15.62 and 55.24±16.76 years, respectively among Group- I and Group-II. They were similar in terms of demographic profile. About 16.0% patients of group- I had vitamin B 12 deficiency and 6.0% had vitamin B 12 deficiency in Group-II. The mean serum Vitamin B 12 was 481.52±283.37 (pgm/mL) in group-I and 600.85±294.2 (pgm/mL) in group-II. The difference of serum Vitamin B 12 was statistically significant (p<0.041) between two groups. Reduced vitamin B 12 also found to be positively associated with duration of metformin intake (p<0.05) and presence of neuropathy (p<0.05).
Conclusion: Metformin is significantly associated with decrease the level of vitamin B12.

Published: December 2022

Purpose of the study: As demonstrated by numerous epidemiological studies, the high incidence of hypertension among patients with coronavirus disease 2019 (COVID-2019) appears to be associated with an elevated risk of mortality. The angiotensin-converting enzyme (ACE) system is not expressed uniformly throughout the human population, and contemporary variations may account for part of the global disparities in infection prevalence. In addition, animal investigations have demonstrated that the ACE2 receptor is a potential infection route for the COVID-19-causing SARS-CoV-2 virus. As two-thirds of hypertension patients take ACE inhibitors/angiotensin receptor blockers, a number of concerns have been raised regarding the harmful or beneficial effects of contemporary antihypertensive medications in COVID-19. This study presents the most recent evidence for and against the impact of ACE blockade administration in the age of COVID-19 on the cohort of hypertension patients in Bangladesh (N = 300). Methods: We included in this study 300 patients who had a record of a COVID-19 test performed between July 2021 and September 2021 using RT-PCR. All the patients had a history of hypertension two years before the index date, based on the International Classification of Diseases codes (Tenth Revision, Clinical Modification, ICD-10-CM). All of them have been taking anti-hypertensive drugs for 1–2 years. We used logistic regression to estimate the odds ratio (OR) and the 95% confidence interval (CI) of COVID-19 severity in patients prescribed Angiotensin Receptor Blockers (ARB) versus those not prescribed ARB. We selected a cohort of 300 Bangladeshi patients who were covid posi tive and had been taking hypertensive medications for 1-5 years. Results: Among COVID-19-positive patients with hypertension, the use of ARB is associated with increased odds of hospitalization, including all patients admitted to ICU or CCU (OR = 1.008, (0.440, 2.309) and OR= 2.31, (0.024, 2.452) respectively). Participants receiving ARB have a lower odds ratio of using BiPAP, CPAP, and Ventilation (0.592, 0.010, and 0.031, respectively; p-value < 0.5) compared to the non-ARB users. Research Implications: We noticed a statistically significant association between ARB administration and mechanical ventilation in our study. Since ARB use was also related to a decreased likelihood of needing additional oxygen support, such as nasal cannula, BiPAP, and CPAP, there is sufficient evidence from other clinical factors to indicate a consistent connection between ARB use and oxygen assistance among covid-positive patients. Further research is required to determine the molecular relationship between ARB use and oxygen level in Covid-positive individuals.

Authors: Akter Maksuda , Shohag Sheikh , Hossain Mohammad Nazir
Published: December 2022

Hypnea musciformis, a red seaweed prevalent in tropical and subtropical regions, has been linked to a multitude of therapeutic benefits. The aim of this study was to investigate the analgesic and anti-inflammatory properties of its extracts in 50% ethanol. Using the hot plate test, the acetic acid induced writhing test, and the formic acid induced test on Swiss albino mice, the analgesic potential of ethanol extracts was examined. Each test was administered at a dose of 500 mg/kg. Alternatively, an ethanol extract from carrageenan-induced paw edema was used in an anti-inflammatory experiment. Diclofenac is used as a reference standard in studies looking at the analgesic and anti-inflammatory effects of substances. In those animal models, our research demonstrates that Hypnea musciformis possesses potent anti-inflammatory and pain-relieving capabilities (percent inhibition found 28.22% on acetic acid method, 42.3% on Hot plate, and 48.7% on Formic acid).

Authors: Rahman Sarkar Md Taufiqur , Alam Mohammad Firoz
Published: December 2022

An efficient in vitro regeneration protocol was developed via callus from the explants of leaf and internode of Coccinia cordifolia (L.) Cogn., an important medicinal climber. Among the different combinations of auxins and cytokines used, BAP with NAA were found highly effective for induction of callus from in vitro derived leaf disc and internode explants. Maximum callus formation rates were recorded on MS with 1.0 mg/l BAP and 0.1 mg/l NAA for both leaf disc and internode explants. The best organogenesis via callus was obtained on MS with 2.0 mg/l BAP and 0.5 mg/l NAA. The highest numbers of shoots regenerated per culture were 6.5 ± 0.10 and 5.6 ± 0.55 for leaf disc and internode explants respectively and leaf discs was found to be better for indirect organogenesis. For root induction, half strength of MS medium supplemented with 0.1 mg/l IBA was found to be the most effective. The mean number of roots regenerated per shoot was 6.8 ± 0.10 with an average root length of 2.8 ± 0.20 cm. In vitro derived plantlets were acclimatized successfully. This protocol for in vitro regeneration can be utilized for the improvement of this climber through biotechnological methods.

Authors: Tabassum Nadra , Jannat Mahbubah , Islam Mohammad Nurul
Published: December 2022

Five species of the Riccia genus have been investigated by Rapid Amplified Polymorphic DNA (RAPD) analysis. The species is explained and demonstrated with its genetic diversity based on morphological variations. Samples were collected from different parts of the University of Dhaka growing in different habitats around the University campus area. After the study of its morphology, it has been observed that the population of this taxon shows significant variation in plant size, shape, colour, ventral scales, appendages of scales, rhizoids, and the position of male and female receptacles, etc. The RAPD marker system was employed to estimate the genetic diversity within and between the populations based on such morphological variations. Approximately 82% of the variations have been observed within and between genotypes of Riccia as revealed with both phenotypic and genotypic data. The RAPD markers are being used increasingly to analyse the phylogenetic relationship among the liverworts to give the exact framework of taxonomic identification of naturally occurring liverwort Riccia.

Assessment of genetic diversity among different is a prerequisite for plant breeders in choosing potential parental lines. Ten genotypes of summer growing chilli including one released variety viz., BARI morich-2; one advanced line viz., SRC- 517 and eight local cultivars viz., IAH-160, IAH-164, AHM-206, AHM-217, AC-63, AC-312, RAI-67, and RI-1(6) were characterized with a view to explore genetic diversity within these genotypes based molecular markers. Using eight microsatellite (SSR) primers across 10 genotypes, a total of 30 alleles with an average number of 3.75 alleles per locus were found. The number of alleles detected varied form three (CAMS-864, CAMS-880, CAMS-885) to five (CAMS-647). The allele size ranged from 160 (CAMS-075) to 289 bp (CAMS-864). All most all sets of primers showed high polymorphism (PIC value ≥0.6) except CAMS-880 and CAMS-885 which suggesting the greater genetic diversity in the genotypes. Gene diversity ranged from 0.460 (CAMS-885) to 0.740 (CAMS-647) and the highest and lowest value of Shannon's Information Index was registered in the same locus with their average value of 1.174. Higher level of genetic differentiation (0.971) and lower level of gene flow value (0.007) which were indicative of the presence of diversity among the genotypes. The genotypes had distinct status in the dendrogram, because of variation in genetic distance values differed from 0.138 to 0.938.

Mango is an important tropical fruit of Nepal. Nepal is rich in mango diversity and large numbers of local genotypes have been identified in different parts of the country. Such diversity of local mango genotypes are in verge of danger and needs to properly identified, evaluated and conserved. Morphological characterization is an important step in the characterization, evaluation and further utilization of genotypes. The current study aimed to characterize 33 local mango genotypes from Doti district of Far Western Region in Nepal using 14 quantitative morphological traits. The results of the study showed variation in terms tree, leaf, fruit, stone and seed character among the genotypes. The average fruit weight of genotypes was found to be 51.61g with maximum weight of 90.92g in Gude genotype. The four major principal components were formed with Eigen value >1 with cumulative diversity of 88.2%. Results of the cluster analysis grouped 33 mango genotypes into four major clusters with similarity level of 41.27% to 96.29% showing diversity among the genotypes. The variability seen among the genotypes in the present study can be a source of gene pool for systematic mango breeding program and thus these genotypes need to be properly conserved.

Authors: Sampa Asma Yeasmin , Alam Md Ariful , Sammy Hasan Mahammad
Published: December 2022

Though the production of maize and the area under cultivation has accelerated, the rate of increase in production is not satisfactory due to its increasing demand with the continuous expansion of the dairy and poultry sectors in Bangladesh. The intended study aimed to identify the factors affecting the production of maize and whether the resources were utilized optimally in the production process. Required data were gathered from 130 maize growers, who were taken through simple random sampling from two districts, Manikganj and Rajshahi, of Bangladesh, through the interview with a pretested questionnaire. The impact of several factors on the productivity of maize was computed with the help of the Cobb-Douglas production function. The study revealed a significant positive impact of seed, land preparation, fertilizer and water management on the final output of maize. Although maize cultivators earned a decent profit, inefficient uses of resources were practiced. Seed and fertilizer were underutilized while labour was over-utilized in the production process. The sampling frame was selected purposively to represent the intensive maize producing area. Farmers shifted to maize cultivation progressively but the high price of seeds, natural calamities and low price of grains may affect production in future.

In Bangladesh, potato (Solanum tuberosum L.) lacks optimum quality for export or processing industries. Optimum utilization of specific plant nutrients can improve quality. The experiment was conducted to evaluate the best dose(s) of phosphorus in combination with potassium sources as they affect potato tuber quality. The experiment consisted the factors: phosphorus dose(4); P1 = 200 kg ha-1 TSP @ 42.55 kg ha-1 P; P2 = 220 kg ha-1 TSP @ 46.81 kg ha-1 P, P3 = 240 kg ha-1 TSP @ 51.06 kg ha-1 P and P4 = 260 kg ha-1 TSP @ 55.32 kg ha-1 P, and potassium sources (3); K1= KCl (250 kg ha-1 KCl @130 kg ha-1 K), K2 = KH2PO4 (452.19 kg ha-1 KH2PO4 @130 kg ha-1 K) and K3 = K2SO4 (288.6 kg ha-1 K2SO4 @130 kg ha-1 K). The interaction of phosphorus doses and potassium sources affected most parameters studied. The highest yield (35.35 t ha-1), caned (10.35 t ha-1), chips (28.06 t ha-1), and French fry (0.367 t ha-1) were from P3K2, P4K2, P3K2, P3K1 respectively; the lowest yield (30.90 t ha-1), caned (5.59 t ha-1) and chips (20.01 t ha-1) were from P1K3, P4K1, P1K3 respectively. The highest dry matter (22.85%), starch (17.936%), antioxidant (630.12 Trolox μMol/100 g FW), and polyphenol (92.994 GA mg/100 g FW) were from P1K3; the lowest reducing sugar (0.1713 mg g-1 FW) and non-reducing sugar (0.3290 mg g-1 FW) were from P1K3. It appeared that 200 kg ha-1 TSP @ 42.55 kg ha-1 P as a dose of phosphorus and K2SO4 as sources of potassium may be a suitable combination to produce export and processing quality potato.

Amelioration of acid sulphate soils in Nilwala river basin
Authors: Senanayake Nanda , Perera MTMDR , Weragoda A
Published: December 2022

Paddy tracts of Nilwala basin has been affected by the implementation of Nilwala Flood Protection and Drainage Project in 1979 due to excessive drainage, and nearly 7000 acres of land is abandoned. The water table goes down to the level of 50 cm below soil surface during dry periods and soil pH falls to 3-4 causing acid sulphate condition. Hitherto several efforts have been made to ameliorate the paddy lands but no any economical solution is obtained. The National Science Foundation project to find out the feasibility of using natural hydraulic forces to increase water table to keep the acid sulphate forming minerals at bay and to cultivate rice in these paddy lands. Water table fluctuation in relation to water level in the drainage channel was studied over one year and there was found a very high correlation (r2=0.985) indicating a possibility of increasing water table by heading up water in the channel. Simulated pot experiment showed that increasing water table to 15 cm below soil surface allows rice to grow effectively, showing plant survival of 112 (53%) compared to 28 (15%) plants in control. Recorded plant height of Bg. 357 variety was 35 cm compared to 22 cm in different treatments and control, respectively. Soil pH also increased to a value closer to 6.0 in the treatment which is conducive for rice cultivation. However, the low values of plant survival and plant heights were due to unusual extreme low rainfall in 2020/21 Maha season compared to 10 years’ average.

Determination of demographic and socio-economic factors influencing clean cooking fuel adoption in rural Bangladesh
Authors: Shabnam Dilruba , Girling Laura
Published: December 2022

Biogas as a clean source of cooking fuel has enormous potential to meet Bangladesh's energy needs. The objective of this article is to identify the factors influence biogas adoption in rural households. The study aimed to look at the policy framework that needs to be put in place to promote biogas adoption as a cooking fuel in the study region. This study collected primary data by interviewing 118 respondents with a structured questionnaire (78 biogas users and 40 non-users) during July-August 2021. Respondents were women who cook for their families regularly. This paper based on a cross-sectional analysis of nine socio-economic and demographic parameters that may influence biogas uptake in Western Bangladesh. The dependent variable, biogas cooking fuel adoption status, was modeled as a dichotomous variable. To evaluate the relationship between independent variables with the dependent variable (biogas user and no-user), bivariate descriptive analysis (t-test for continuous data and chi-square test for categorical data) was performed. Then, a binary regression model was chosen to determine the adjusted effect of independent variables on biogas adoption decisions. The study found that the demographic factors such as income status of the women, education of household head, family size and total family income significantly and positively influence biogas adoption decisions. Contrary to the hypothesis, access to internet and total land area owned by the family show negative relation with biogas cooking fuel adoption status of the household. The outcome of this research added evidence to support energy policy with giving emphasis on subsidy, and adult education in rural areas.
