Abstract:
This research investigates the adoption of rice cultivation technology on producers technical efficiency in the Tonlesap plain of Cambodia. It also provides the factors that influenced technical efficiency in this study area. Using the Cambodian socio-economic surveys of 1944 households conducted in 2014, 2015 and farmers record book of 408 households conducted in 2017, 2018, the Stochastic frontier analysis (SFA) is employed for analysis. From the Maximum Likelihood Estimation (MEL) of the Tran-slog production function and technical inefficiency model, the result reveals that the overall technical efficiency is estimated at 79.56 percent on average. In comparison, the mean of technical efficiency is recorded at 75.56 percent for nonadopter and 98.45 percent for adopters. It means that rice production in Tonlesap plain was producing under the efficient frontier for both groups of farmers. Fertilizer and pesticide cost are the major factors that improve rice output per household, followed by seed and labor. However, these three inputs are decreased in the square term, implying that when all production variables are increased by a certain percentage resulting in a less-than-proportional increase in output. Moreover, farmland, adoption status, access to water, and farm location have a positive effect on technical efficiency in Cambodian rice production
