The study was conducted in Rwanggchhari and Ruma upazila of Bandarban district, Bangladesh. This study explored farmers’ perception towards land use change and the factors contributing to their perception. Following a proportionate random sampling technique, a total of 120 households were sampled and survey was administered through a predesigned close ended questionnaire. A substantial number of respondents (54%) were more than 40 years old, of whom 51% were educated with an average family size was five. The respondents had an average annual income of BDT 91830. An average land holding was 3.59 acres were seen in the study area and these lands were occupied with agricultural, forest, vegetable lands and also with flat and hilly lands. Meanwhile, 98% farmers maintained medium to higher perception towards the changes of land distribution. In addition, out of eight attributes, three attributes, namely, educational attainment, agricultural training received and hill land ownership had significant influence on the perception of land use change by the respondents. The findings of the study can be utilized by the policy makers and planners of the country to formulate future land distribution policy of the CHT in future.\u0000Ann. Bangladesh Agric.

Over the past few decades, flash floods have frequently affected the livelihood of people in the Sylhet Haor Basin. This study highlights the causes of increased flash floods, their impact on farming practices and livelihoods, and possible solutions to flash flood risk in the Sylhet Haor Basin. Data were collected using a pre-tested structured questionnaire from randomly selected 298 Haor farmers in high and moderately vulnerable flash flood zones across the Haor region during November 2021 and April 2022. In moderately vulnerable areas, the lack of rivers and canal dredging was the main factor contributing to flash flood deterioration. Index scores and ranks revealed that flash floods most severely affect the primary production sector (agriculture) and threaten the lives and livelihoods of the local populace in high- and moderately flood-prone areas. After the severe flash flood, farmers were forced to turn to other occupations instead of agriculture for their livelihood. To reduce the impact of flash floods on particular features or entire wetlands, most farmers preferred the construction of embankments over sandbags, concrete or stone dams, submergible embankments, and rubber dams. For flash flood risk management, farmers in high- and moderately flash flood-vulnerable areas emphasize the construction of higher dams and embankments and the installation of more flood barriers (dams/embankments). The concerned flash flood management agencies could incorporate the key findings of this study while formulating risk mitigation strategies for the Sylhet Haor Basin.\u0000Ann. Bangladesh Agric.

The IVM of the oocytes was evaluated by observing the degree of cumulus cell (CC) expansion and extrusion of the first polar body (PB-1) as well as both nuclear progression (NP) and cytoplasmic maturation (CM). For NP, after 24 h of IVM, oocytes were denuded and stained with DNA fluorochrome and observed under an epifluorescence microscope. The male or female pronucleus (PN) forming ability of an oocyte following in vitro fertilization (IVF) was considered as CM. For CM, the fertilized zygotes after 24 h post-insemination were stained with DNA fluorochrome and observed under an epifluorescence microscope. Results revealed that the maturation rate was significantly influenced by the reproductive phase of the oocytes donor, luteal phase ovaries (LPO) versus follicular phase ovaries (FPO) based on the presence or absence of corpus luteum (CL), respectively. The significantly higher CC expansion (2°; 44.9±4.9% versus 35.9±2.7%) and PB-1 extrusion (58.3±1.7% versus 46.7±2.4%) were observed with LPO than FPO oocytes, respectively. A significant (p<0.05) effect of the reproductive phase was also noted with LPO oocytes progressing higher rate of mature metaphase II stage (MII; 58.3±1.7% versus 46.7±2.4%) and PN (54.9±2.3% versus 44.4±3.0%) formation following IVF than FPO oocytes that imply better NP and CM of oocytes, respectively. Therefore, the present study indicates that the reproductive phase of oocyte donors notably from LPO positively influences the IVM of bovine oocytes to produce a higher number of viable embryos in vitro.\u0000Ann.

Gazipur district is one of the largest industrial zones in Bangladesh. Every day a huge amount of untreated industrial effluents is produced and delivered to the nearby crop field or water body. These effluents might have influenced the major chemical properties of soils. Hence, the present study was conducted to assess the impact of untreated industrial effluents on soil chemical properties expressed through a spatial distribution pattern map of the industrial zone of Gazipur district. A total of one hundred and four agricultural soil samples were collected with grid basis from different unions of the industrial areas of Sreepur and Gazipur Sadar upazilas. In Sreepur upazila, the mean values of soil pH, organic carbon (OC), N, P, S, K, Ca and Mg were 4.85, 0.81%, 0.11%, 6.08 ppm, 26.5 ppm, 0.13 meq/100g soil, 0.53 meq/100g soil and 0.19 meq/100g soil, respectively in uncontaminated soil, while the mean values of soil pH, OC, N, P, S, K, Ca and Mg were 5.15, 1.96%, 0.23%, 14.2 ppm, 187.61 ppm, 0.15 meq/100g soil, 0.64 meq/100g soil and 0.2 meq/100g soil, respectively due to industrial contamination. In both the upazilas, soil pH was strongly to slightly acidic while soil organic carbon was low to medium and N content was low. A weak spatial variation was detected for soil pH and N in these industrial areas indicating less influence on both the parameters by the effluents. Similarly, the contents of K, Ca and Mg were low in most of the areas of these two upazilas and a very little or no spatial variation was observed. On the other hand, OC and P contents were low to medium whereas S content was high in most of the study areas.\u0000Ann. Bangladesh Agric.

Analysis of variance exhibited highly significant variability among the genotypes and combining ability variances for most of the studied traits except grain length and length-breadth ratio. The results indicated that none of the parent and hybrid combination performed better as general and specific combiner for all the traits. Performances were found to vary from trait to trait among parents and hybrid combinations. Parental genotype P3 performed as the best general combiner for grain yield hill-1 (2.16**) followed by P5 (1.43**). The hybrid combination P3×P5 exhibited the best specific combiner for grain yield hill-1 (5.17**) followed by P3×P4 (5.06**). However, the GCA : SCA ratio was less than unity for panicle length, effective tillers plant-1, filled grains panicle-1, straw dry weight and grain yield hill-1 indicating the presence of non-additive gene action. The results revealed that these traits could be improved through hybridization between the parents P3 and P5.\u0000Ann. Bangladesh Agric.

Developed products were evaluated for their chemical properties as well as sensory attributes. In addition, selected products were tested for shelf-life potentials. Formulated drinks and juices were found as highly nutritious (maximum of 6.86 mg/100 ml ascorbic acid, 0.045% Ca, 0.26% Mg, 0.154% K, 0.034%Na, and 12.09 ppm Fe). Sensory evaluation revealed that products with 20% and 40% aloe vera pulp with pineapple and roselle extract were highly liked by the consumers. With the storage time, pH and ascorbic acid content decreased (maximum around 40% for pH and around 10% for ascorbic acid respectively) in all the formulated beverages, while TSS increased regardless of the formulations. In addition, aloe vera with pineapple and sugar blend exhibited an acceptable level of microbial load during the shelf-life study. Results from this study suggest that it could be possible to commercially produce aloe vera based value added products, which in turn could play an important role in addressing socioeconomic as well as health conditions.\u0000Ann.

Whereas ascorbic acid (AsA) involves in various physiological and biochemical processes; and acts as a ROS scavenger. Therefore, the experiment was conducted to investigate the effects of exogenous application of AsA on growth and yield of tomato plants. The ROS scavenger AsA was applied in the leaves of tomato plants in four treatment combinations (T1-Control; T2-0.5 mM; T3-2.0 mM and T4-4.0 mM) with three replications. Among the treatments, AsA at 4.0 mM (T4) efficiently increased leaf length (12%), inflorescence length (17%), and flower number (29%) than the untreated control plants. AsA at 0.5 and 2.0 mM also showed positive effects on the plant morphology to a lesser extent. Importantly, AsA at 4.0 mM increased yield by 18% than the control treatment. In physiochemical parameters, AsA at 4.0 mM (T4) was retained 64.07% higher chlorophyll content than the control plant even after 60 days of application. Exogenous application of AsA effectively reduced oxidative stress of the plant, which was attributed to the less accumulation of H2O2 and lipid peroxidation of membrane lipids. AsA at 4.0 mM decreased H2O2 and MDA accumulation by 39% and 45%, respectively, compared with the control plants. Therefore, exogenous application of AsA is a useful tool to enhance growth and yield of tomato under field conditions by lowering the accumulation of ROS and lipid peroxidation.\u0000Ann.

The present study was conducted to screen the in vitro inhibitory effects of garlic extracts on Aeromonas veronii isolated from MAS, evaluate the effects of dietary inclusion of garlic extracts on growth and prevention of MAS in Labeo rohita. In vitro antibacterial activities of garlic aqueous and organic solvent extracts (ethyl acetate, methanol, ethanol, and acetone) were screened by disc diffusion assay. The minimum inhibitory concentrations (MICs) of ethyl acetate and methanol extracts were determined by using a quantitative bioassay method. Four groups of fish were fed garlic ethyl acetate extract at the rate of 0 (T1, control), 6.25 (T2), 12.50 (T3), and 25.00 (T4) mg/kg feed with three replications for 90 days. The fish fed with different concentrations of garlic extracts were artificially challenged with the high virulent A. veronii strain B55. In this study, ethyl acetate extract of garlic inhibited all the A. veronii strains (A22, B7, B9, B19, B27, B36, B55, F143, K743, and L1324) with the maximum inhibition zones. The MICs of ethyl acetate and methanol extracts were obtained 31.25 and 62.5 μg/ml, respectively. The final weight gain of L. rohita was obtained 28.21±0.51, 31.33±0.76, 40.05±0.76, and 34.82±0.51 g in the treatments T1, T2, T3, and T4, respectively. The growth of ethyl acetate extracts-fed fish were significantly (p < 0.05) higher compared to the control. The specific growth rate was also found significantly higher in the T3, T4, and T2 relative to control. The fish fed garlic extracts enriched feed at 12.5, and 25 mg/kg developed resistance against MAS, while all the control fish died with expressions of distinct disease symptoms.
