Technological advancements have long played crucial roles in rice productivity and food security Bangladesh. Seasonal variation over time regional differences production, however, pose a threat to agricultural sustainability but remain unexplored. We performed spatial-temporal mapping of cultivation area, yield from 2006–2007 2019–2020 using secondary data for disaggregating 64 districts Growth multivariate approaches were employed analyze time-series data. Results showed that Mymensingh had the highest cultivated area while Bandarban lowest. The 14 years average was found Gopalganj Dhaka (3.63 tons/ha), Patuakhali (1.73 tons/ha) For Aus, Aman, Boro, 19 districts, 11 13 declined significantly. overall production increased significantly most districts. Boro seasons, 54, 50, 37 demonstrated significant upward trend, respectively. adoption rate modern varieties has risen dramatically. However, there are notable variances between regions seasons. A increasing trend Aus (0.007% 0.521%), Aman (0.004% 0.039%), (0.013% 0.584%) observed 28, 34, 36 respectively, with an increase 1% adaptation HYV. Predictions revealed seasons will be Bangladesh by 2030. Based on spatiotemporal cluster analysis, five identified groupings illustrated clusters lack spatial cohesion vary greatly seasonally. This suggests expanding cultivable land, adopting high-yielding varieties, integrating faster technological advancement research extension. findings assist scientists developing region-specific technologies policymakers designing decentral policies ensure future production.
