The main purpose of the study was to evaluate farmers socio-economic status, attitude and relationship among them towards organic farming. The study was conducted in five upazilas of Chapainawabganj district in Bangladesh. A simple random sampling technique was used to select 40 respondents. Attitude of respondents toward organic farming was measured with twenty statements using five point likert type scales. To explore the relationship between the concerned variables correlation coefficient (r) was computed. Descriptive statistics were used to describe the variables. Majority of the respondents were male (90%), average age was 44 years. 45% respondents were illiterate, had average 4 years of farming experience. Majority of the respondents (80%) had positive attitude towards organic farming. Relatives and Extension Agents were found as the main information source of organic farming for most of the respondents. Cosmopoliteness and Extension contact had positive and significant relationship with their attitude (.461 and .377 respectively). It was concluded that farmers were knowledgeable about organic farming and also had favourable attitude toward its practices. Efforts should therefore be made to promote and increase the practice of organic farming. By promoting organic farming practice, farm income is increased than conventional farming.

The global promotion of electric vehicles (EVs) through various incentives has led to a significant increase in their sales. However, the prolonged charging duration remains a significant hindrance to the widespread adoption of these vehicles and the broader electrification of transportation. While DC-fast chargers have the potential to significantly reduce charging time, they also result in high power demands on the grid, which can lead to power quality issues and congestion. One solution to this problem is the integration of a battery energy storage system (BESS) to decrease peak power demand on the grid. This paper presents a review of the state-of-the-art use of DC-fast chargers coupled with a BESS. The focus of the paper is on industrial charger architectures and topologies. Additionally, this paper presents various reliability-oriented design methods, prognostic health monitoring techniques, and low-level/system-level control methods. Special emphasis is placed on strategies that can increase the lifetime of these systems. Finally, the paper concludes by discussing various cooling methods for power electronics and stationary/EV batteries.

Wheat (Triticum aestivum L.) demand in Bangladesh has increased significantly in recent years, becoming the second major staple cereal after rice (Oryza sativa L.). Domestic production of wheat accounts for only 16% of domestic use. More than 30 wheat varieties have been released in the past 30 yr by the Bangladesh Wheat and Maize Research Institute (BWMRI). In the last 10 yr alone, nine varieties with improved yield and disease resistance have been released. Bangladesh and the BWMRI lack the regulatory framework and infrastructure to accurately track the rate of adoption of these new releases. To determine the adoption of these varieties across the country, DNA fingerprinting of wheat samples was conducted across the six wheat growing regions in Bangladesh during the 2018–2019 cropping season. A reference library was established to compare and identify the wheat samples collected from farmers’ fields. Wheat grain samples collected from the fields and breeders’ lines were genotyped using Diversity Arrays Technology sequencing (DArTseq)‐based single nucleotide polymorphism (SNP) markers. Of the 1,791 samples collected from farmers’ fields, 68% were identified as varieties released after 2000 and 32% matched with older varieties. Among the varieties grown, BARI Gom 25 represented 29% of the collected samples followed by 23% of BARI Gom 24 and 16% of BARI Gom 26. These three most common varieties were well distributed across the six regions and have broad adoption.
