This study was conducted with the objective to estimate technical efficiency of farm producing rice with special emphasis on aromatic, fine and coarse rice varieties in Bangladesh. This was done for understanding the determinants of technical efficiency that may help designing rice production profitably and minimizing farmers' yield gap with given technology and resource constraints and to provide future policy guidelines for researchers and public support services. Farm-level cross-section data were collected from one of the intensive rice-growing areas of Dinajpur. A set of statistical and non-statistical stochastic approaches to frontiers have been used to estimate production efficiency. The application of the translog stochastic production frontier model gave the best fit for technical efficiency analysis. The estimated mean efficiency was 97% for aromatic, 98% for fine, and 85% for coarse rice farmers indicating that there is little scope of increasing yield without breaking the yield frontier particularly for aromatic and fine rice through introduction of high yield potential varieties. For coarse rice varieties, 15-16% yield could be increased even with the existing varieties, if the management practices of the parameters identified in this study are improved.
