This study evaluates the effectiveness of the Khamari Mobile App, a geospatially enabled crop production advisory tool aimed to improve productivity and profitability in Bangladesh’s agricultural sector. Field-level demonstration trials were conducted for 14 major non-rice crops during the Rabi and Kharif-I seasons of 2022–23 and 2024–25 across diverse Agro-Ecological Zones (AEZs). Fertilizer recommendations generated by the Khamari app were evaluated in terms of fertilizer-use efficiency, crop yield, and economic returns, and compared with farmers’ conventional practices. The results indicate that app-based recommendations significantly reduced fertilizer use by 10–78% while increasing crop yields by 0.84–26.33%, resulting in higher net economic returns. Statistical analysis using a t-test at the 5% significance level confirmed that differences in fertilizer costs and yields between the two practices were statistically significant. These findings demonstrate the potential of Khamari app, as a geospatial decision-support tools, to enhance resource-use efficiency, farm profitability, and sustainability in Bangladesh’s agricultural systems, while also providing policy-relevant insights for reducing excessive fertilizer use and associated subsidy burdens.
