Mungbean (Vigna radiata) is a key pulse crop in Bangladesh, playing a crucial role in the country's agricultural economy and food security. However, challenges such as soil degradation, nutrient depletion, and low yield potential hinder its productivity. This study investigates the effects of integrated nutrient management (INM) practices, including vermicompost, on the yield, quality, and soil health of mungbean (Vigna radiata) in the coastal region of Gopalganj, Bangladesh. A randomized complete block design (RCBD) was employed with three treatment groups: control (traditional inorganic fertilizers), organic fertilization (vermicompost), and integrated nutrient management (a combination of organic and inorganic fertilizers). Results indicated that the INM treatment significantly improved the emergence rate, with 85% of seeds emerging within 8 days, compared to 75% and 70% in the organic and control treatments, respectively. Plant growth parameters, including plant height (60 cm) and the number of leaves (15), were highest in the INM treatment, followed by the organic (50 cm and 12 leaves) and control treatments (45 cm and 10 leaves). The INM group also showed the highest mungbean yield (26 tons/ha), with larger average tuber weight (180 g) and fewer defects (5%), compared to the organic (22 tons/ha, 160 g, 10% defects) and control groups (20 tons/ha, 150 g, 15% defects). Soil health assessments revealed significant improvements in soil nutrient content, including nitrogen (24 mg/kg), phosphorus (18 mg/kg), and potassium (230 mg/kg), and higher microbial activity (130) in the INM treatment, suggesting enhanced soil fertility. These results highlight the potential of INM practices in improving mungbean productivity, quality, and long-term soil health, offering a sustainable approach to agriculture in Bangladesh. This study underscores the importance of adopting integrated fertilization strategies to achieve higher crop yields and ensure soil sustainability.

This study evaluates the impact of integrated nutrient management (INM) practices on potato yield and quality in the coastal regions of Bangladesh. Potatoes are a vital crop in Bangladesh, and optimizing nutrient management is crucial for enhancing productivity and ensuring sustainability. The research was conducted in multiple agro-ecological zones in Gopalganj, where field trials were established with three treatment groups: traditional fertilization practices, organic fertilizers, and a combination of organic and inorganic fertilizers (INM). The results demonstrated that INM practices significantly improved potato yield and quality compared to traditional practices. Specifically, the INM group exhibited a 20% increase in yield and enhanced tuber quality, characterized by higher nutrient content and reduced incidence of common diseases. Soil health parameters, including microbial activity, nutrient availability, and organic matter content, were also positively influenced by INM practices. Economic analysis revealed that, despite higher initial costs, INM practices were more cost-effective in the long run due to reduced fertilizer input and improved crop yield. This study highlights the importance of adopting sustainable nutrient management strategies to improve potato production in Bangladesh. The findings underscore the potential of INM practices to enhance food security and support sustainable agricultural development. By integrating organic and inorganic fertilizers, farmers can achieve higher yields, better-quality produce, and maintain soil health, making INM a viable strategy for the future of potato farming in Bangladesh.
