  Background and Objective: Thai government launched a Large Agricultural Plot Scheme (LAPS) in 2005 in order to enhance the effectiveness of the extension programme. The objective of this research was to compare the technical efficiency (TE) of oil palm production and factors influencing the TE of oil palm production between member and non-member farmers under the LAPS in Bang Saphan Noi district, Prachuap Khiri Khan Province, Thailand. Methodology: The data were collected from January-June, 2017 from 57 LAPS member farmers and 63 non-LAPS member farmers. This paper estimated technical inefficiency by using a stochastic production frontier model and Tobit regression to investigate the factors influencing the TE. Results: The results revealed that the TE of oil palm production of the LAPS member farmers was ranked 12-99%, whereas that of the non-LAPS member farmers was ranked 14-99%. The TE mean of LAPS member farmers was 0.63, while the TE mean of non-LAPS member farmers was 0.52. The years of experience on oil palm plantations and age were crucial factors that contributed to the TE of LAPS member farmers and TE of non-LAPS member farmers, respectively. Conclusion: The TE mean of LAPS member farmers was higher than that of non-LAPS member farmers knowledge and experience sharing between old and young generations who are eager to work in oil palm production should also be a concern.

  Background and Objective: Generally, there are three different rice farming production systems: Farming under the agriculture network, conventional organic rice farming and chemical rice farming. This study estimated the technical efficiency (TE) of different production systems for rice farming in eastern Thailand. Materials and Methods: Chachoengsao and Prachinburi were selected as the study areas. Farm-level data were collected during the 2016-2017 production period from 150 respondents consisting of 58 organic farmers under the Alternative Agriculture Network (AAN), 42 conventional organic rice farmers and 50 chemical rice farmers. A stochastic frontier analysis was employed to analyze the survey data. Results: The results indicated that the technical efficiency scores for organic rice farmers under the AAN had the highest level of efficiency compared to conventional organic rice and chemical rice farmers. The average TE of the farmers under the AAN was approximately 0.733, ranging from 0.375-0.940, while the average TE of the conventional organic rice farmers was approximately 0.669, ranging from 0.103-0.948 and the average TE of the chemical rice farmers was approximately 0.688, ranging from 0.293-0.999. The results indicate that farmers should use high-quality seeds and organic fertilizer to improve the efficiency of organic rice. Conclusion: The findings indicated that the technical efficiency scores for organic rice farmers under the AAN had the highest level of efficiency comparing to conventional organic rice and chemical rice farmers.
