A survey was carried out on the Patuakhali Science and Technology University (PSTU) campus, Narsingdi, Sylhet, Hobigonj, and Mowlovibazar districts of Bangladesh to know the incidence pattern of insect pests of French bean from November 2016 to January 2017. Field screening of nine French bean varieties against major insect pests was conducted in the Regional Horticulture Research Centre, BARI, Shibpur, Narsingdi, from November 2017 to January 2018. Seven varieties viz., BARI Jharsheem-1, BARI Jharsheem-2, BARI Jharsheem-3, Sylhet local- 4, Sylhet local-5, Sylhet local- 6 and Sylhet local-7 were used as study materials to evaluate against major insect pests of French bean under natural field condition. Results revealed that black fungus gnat was first noticed on 13th December, 2016 and the prevalence continued upto the 12th January, 2017. The highest incidence (21/plant) of black fungus gnat was found in Habiganj and the lowest (9/plant) was on the PSTU campus. The highest number of black fungus gnats were captured at 38 DAS (89/trap) and the lowest number (56/trap) of black fungus gnats were at 28 DAS using a yellow sticky trap. The variety BARI Jharshim-3 had the highest population of Black fungus gnats, which indicated that the variety was highly susceptible to Black fungus gnats, while Sylhet local-7 had the lowest population of black fungus gnats indicating least susceptible to Black fungus gnats. Among all tested varieties, none showed complete resistance against black fungus gnats.\u0000J. Asiat. Soc.

The present research has focused on palynological investigation, X-ray Diffraction analysis, and elemental analysis of the core coal samples of the Gondwana coal of the Barapukuria Basin. The palynological study identifies two Palynoassemblage zones (Zone I and Zone II). A non-striate desiccate Scheuringipollenite, Crucisaccites, Parasaccites palynoassemblages are identified as Zone I and denotes as Lower Barakar Palynozone in the Early Permian where Zone II is dominated by striate desiccate Barakarites, Faunipollenites, Callumispora Palynoassemblages in the Late Permian. The Glossopterid plant family ruled the botanical affinity of Zone I and Zone II. It rendered the Gymnosperm group of plants as the rapid deglaciation assisted dissemination of Glossopteris flora. Higher percentages of clay minerals in X-ray diffraction (XRD) analysis and higher amounts of carbon content, lower sulfur, and higher C/S>10 ratio in the elemental analysis have been identified. All evidence from the research suggests that coals were deposited when glaciers retreated in the Early Permian, and the Gymnosperm group of plants prevailed and accumulated in the warm and humid climatic conditions under the braided fluvial influence in the terrestrial environment.\u0000J.

This study aimed to quantify the bamboo growth in inundated areas at minimound, plain land, and barren land and under the S. apetala plantation and characterize the impact of inundation, soil pH, and soil salinity. The experimental plantation was carried out by B. vulgaris and B. balcooa on a mini-mound on barren coastal raised land in 2018. Other experiments of B. vulgaris were carried out on mini-mound and plain land under the S. apetala plantation in 2019 and 2020. Seedlings were raised by branch cutting. Mini mounds were prepared with soil. The soil sample was collected at different depths in off-peak and peak periods to determine soil pH, electrical conductivity (dsm-1), and nitrogen%. The growth of B. vulgaris in survival (p-value 0.0004) and new culms initiation% (p-value 0.0068) were significantly higher than B. balcooa in the barren land. Soil electrical conductivity showed significantly higher in all soil depths at barren land than under S. apetala forest in off-peak (p-value 0.0000, 0.0000, 0.0016) and peak periods (p-value 0.0002, 0.0028, 0.0000). The higher soil salinity affects the growth of two bamboo species. The higher soil pH affected the growth of B. balcooa on barren land. The growth performance of B. vulgaris showed significantly better survival% (p-value 0.030), height (p-value 0.0010), girth (p-value 0.011), total culms per clump (p-value 0.0086), and new culms initiation% (p-value 0.022) on the mini mound than plain land under S. apetala forest in 2019 and 2020 except height growth.

Data from the landsat satellite images have been analyzed using the NDWI and the supervised image classification approach. The study results demonstrate that the deep water area in Dharmapasha and Tahirpur upazila have declined by more than 17 km2, and 26 km2, respectively, between 1989 and 2019. In addition, due to overexploitation and mismanagement, the wetland resources have been greatly reduced, leading to degradation.

The most frequently utilized plant populations were herbs, followed by trees, shrubs, and climbers. Oral consumption was the main mode of treatment in the study area and was followed by external application. The highest factor of informant consensus (Fic) values was found in heart disease, followed by diabetes, gastrointestinal disorders, skin disease, respiratory disorders, sexual disease, and cuts and wounds. In the present survey, eight species have attained a fidelity level of 100 percent (Fl). Among the plants, 25 species have been used to treat cardiovascular diseases.

To find out the response features of salinity tolerance in mungbean, a series of experiments were carried out in the Department of Crop Botany of BSMRAU. The experiment was performed in the greenhouse of the Crop Botany department using nutrient solution under hydroponics conditions. Initially, fifty-two mungbean genotypes were used in the experiment to screen out a susceptible and tolerant genotype. The results indicated that salinity affected the plants at various morphological characteristics namely plant height, and dry matter of root, stem, and fruit. The genotypes were placed in four groups based on their performance in salinity. A higher quantity of proline with a lower amount of Malon-dialdehyde was observed with the increase in salinity. Chlorophyll content increased initially and after that declined sharply. The susceptible genotype resulted in a sharp decline of chlorophyll and increased proline content which reflected the 1accumulation of root and shoot dry matter, and consequently, the total dry matter content compared to that of the tolerant genotype.\u0000J.
