The Measurement of Technical Efficiency on Certified Organic Jasmine Rice Farms


Charuk Singhapreecha and Nitipong Songsriroj


This study measured technical efficiency on certified organic Jasmine rice farms with data envelopment analysis (DEA) and stochastic frontier analysis (SFA). Data was obtained from 150 farms in Yasothon province in the crop year 2005/06. The results show that technical efficiency from DEA were 41% and 54% for constant returns to scale (CRS) and variable returns to scale (VRS), respectively, while the result from SFA was 67%. The study also found excessive use of seed, labor, machinery, and fertilizer. The optimal farm size should be 21 rai (3.36 ha) which would yield 324 kg/rai (2.03 tons/ha). The efficiency results from SFA and DEA (CRS) were more consistent than those from SFA and DEA (VRS).

Keywords:   technical efficiency, data envelopment analysis, stochastic frontier analysis, organic Jasmine rice
