Purpose: The purpose of this study was to determine the effect of agricultural exports and imports on economic growth in Bangladesh and propose an upgraded and customized model of the supply chain for agribusiness growth in Bangladesh to achieve plain sailing and systematic operation and financial gains at home and abroad. Research design, data, and methodology: All data in the research have been collected from secondary sources. Gross domestic product was used as the dependent variable and exports and imports of agricultural products were used as independent variables. Pairwise Granger causality was utilized to see the impact of the variable responsible for the economic growth in Bangladesh and the causal relationship between the variables analyzed was measured using Johansen co-integration test. Results: From the empirical analysis, the researchers observed that agricultural commodity imports and exports have a unidirectional impact on economic growth in Bangladesh and a long-run causal link with economic growth in Bangladesh. The suggested supply chain model of agnbusiness aids in achieving smooth operations, systematic management, and monetary gains both domestically and internationally. Conclusions: This paper contnbutes to the development of a more effective and profitable agribusiness supply chain in Bangladesh systematically through their theoretical and practical implications.

Water hyacinth (Eichhornia crassipes) has been used in phytoextraction to uptake heavy metals and trace elements in various experiments. This research investigated the protective effects of Water hyacinth extracts on Lead (Pb)-induced toxicity in the albino rat. Forty-eight six-weeks-old Wistar albino male rats (average weight, 180 ± 6.45 g) were divided into six groups: normal control (NC), Pb control (PbC), Chloroform extract (ChEx), Ethyl acetate extract (EAEx), Methanol extract (MeEx) and Ascorbic acid treated groups (AA, positive control). All animals except NC group have been administered with Lead acetate (Pb(CH3COOH)2) before the therapeutic dose. Thrombolytic and cytotoxic effects were evaluated by modified clot lysis and Brine shrimp lethality tests respectively. Biochemical analyses reports revealed that ChEx significantly (P ≤ 0.05) reduced the elevated alkaline phosphatase (ALP) and aspartate amino transferase (AST) whereas MeEx did the alanine amino transferase (ALT) in comparison to positive control. ChEx significantly inhibited the Pb deposition in kidney and liver than two other extracts. ChEx significantly increased the liver protein compared to PbC group. In the thrombolytic assay, EAEx showed the pronounced clot lysis (49.24 %) while ChEx and MeEx showed 45.18 % and 29.13 % of clot lysis respectively. In Brine shrimp lethality bioassay, the LC50 value of the ChEx, EAEx and MeEx were 4.16, 4.47 and 9.27 μg/mg respectively and values were statistically significant (p < 0.05) compared to that of reference cytotoxic agent, Vincristine sulfate (LC50’ 0.55). Histopathological screening of kidney, liver and spleen showed that ethyl acetate extract recovered the highest of the cellular damage caused by Lead acetate. Biochemical and histopathological screening, therefore, demonstrate that Water hyacinth could be one of the promising sources of normalizing the Pb-poisoning and enhancing the thrombolysis in an animal model. Therapeutic prospects of Water hyacinth could be further studied through highlighting a dose-response study.

Identification of physiological markers related with salt tolerance during various vegetative and reproductive stages is crucial for evaluating wheat genotypes and improving their salt tolerance. Two salt-tolerant (Shatabdi and BAW 1135) and two salt-sensitive (BARI Gom 26 and BAW 1122) wheat genotypes of Bangladesh were grown in three salinity levels (control, 6 dS m-1, and 12 dS m-1) to observe the sensitivity of some physiological traits.. Salt-tolerant wheat genotypes maintained lower levels of leaf Na, higher levels of leaf K, and greater K/Na ratios in saline conditions than the sensitive one. Due to salt stress, flag leaf proline content was increased in salt-tolerant wheat genotypes whereas the proline level was decreased in the sensitive one compared to the control. Salt-sensitive genotypes showed a greater increment in SPAD (relative chlorophyll content) value at moderate salt stress but a greater reduction in SPAD values at high salt stress than tolerant ones. Salt-sensitive genotypes were affected more in their straw yield and finally grain yield plants-1 under saline conditions than salt-tolerant genotypes. There was a highly significant negative correlation between grain yield and Na content and also a highly significant negative correlation between grain yield and K : Na content of the wheat genotypes under saline environments. We also observed stress susceptibility index (SSI) based on grain yield plant-1 the order of tolerance was BAW 1135 > Shatabdi > BARI Gom 26 > BAW 1122 at moderate salinity level and BAW 1135 > Shatabdi > BAW 1122 > BARI Gom 26 at high salinity

To examine the effect of high temperature during seed development and maturation on seed quality of wheat, seeds of four heat-tolerant and two heat-sensitive wheat genotypes obtained normal and high temperature growing conditions were tested for quality. High parent plant growth temperature during seed development and maturation resulted in poor seed quality. The effect of parent plant growth temperature on seed germination and speed of germination was inconsistent between heat tolerant and heat-sensitive wheat genotypes. Seed vigor as indicated by seed density, conductivity of seed leachates, seedling dry weight, production of normal seedlings, seed reserve utilization efficiency, and seedling emergence were reduced in all wheat genotypes due to higher parent plant growth temperature but heat-sensitive wheat genotypes were affected more than the heat-tolerant genotypes.

In this study, the interaction of pH, biomass and initial concentrations of lead (Pb) and manganese (Mn)ions in simultaneous removal of Pb and Mn were investigated using the Box–Behnken design. The resultsshowed that there was a significant interaction between pH-Pb:Mn concentrations, pH-biomassconcentration and Pb:Mn-biomass concentrations. The maximum uptake of Pb and Mn was achieved atpH 7. By increasing the Pb and Mn concentrations from 10 to 50 mg/L, the uptake capacities alsoincreased. By increasing the biomass concentration from 0.3 to 1.5 g/L, the uptakes (g/g) of both metalions by Bacillus cereus I6 was depleted. The precipitation of Pb and Mn on the surface of B. cereus I6 cellswas confirmed by energy dispersive X-ray (EDX) transmission electron microscopy (TEM), and Fouriertransform infrared (FTIR). Thus, simultaneous biosorption of Pb and Mn by isolated I6 strain can beefficiently performed under different interactions of environmental factors.

Natural diets commonly exploited by the flies are animal manures including production from the poultry and livestock facilities. The larvae of the common filth flies such as Musca domestica and Sarcophaga dux are known as voracious feeders and may thus be used to convert manures into non-polluted residue. This study was conducted to observe the impact on flies' growth rate and capability of the larvae to process animal manures using chicken, goat and cow manures. One hundred newly hatched larvae of M. domestica and S. dux were introduced separately into 150 g manures under laboratory conditions. The initial wet mass and larvae length were recorded while mortality rate and dry mass were measured after the larvae were placed into the manures. The results showed that the manure types give significant effects (p < .05) on the growth of M. domestica and S. dux larvae. Cow manures and chicken manures contributed the highest growth for M. domestica and S. dux respectively. This result confirmed by the mean increment in wet mass and larvae length. In contrast, M. domestica greatly reduced 59.9 ± 4% chicken manures while 25.0 ± 1.8% goat manures reduced by S. dux. The potential of M. domestica and S. dux larvae to reduce animal waste products were further discussed in this study.

This study was conducted to determine an effective completion point of the simultaneous removal ofNH4+–N and Mn2+, using a biological aerated filter (BAF). The simultaneous removal was performed andmonitored under two operation modes: i.e., batch and continuous. Each mode was operated bysupplying continuous aeration for 7.5 h and intermittent aeration for 6 h. The results showed a higherperformance of the simultaneous removal of NH4+–N and Mn2+ for the batch with full operation ofaeration. The effective curves were detected for dissolved oxygen (DO), oxidation-reduction potential(ORP) and pH profiles, correlating with the complete simultaneous removal of NH4+–N and Mn2+. Byrecognising the curves, the complete simultaneous NH4+–N and Mn2+ removal can be predictedeffectively, affecting a reduction in human capital and operating costs.
