Impact assessment of research and promotion of technology set for planting Sisaket 13 chili in Nan Province

Abstract

The technology set for planting Sisaket 13 chili has been promoted to farmers in order to reduce losses from the Anthracnose disease in chili by the Nan Agricultural Research and Development Center since 2007. The overall objective of the study was to evaluate the impacts of the research and promotion project of the technology set on yield and income. The study assessed the adoption of technology by using the Logit Model, and evaluated the benefits via the Economic Surplus approach. Bias was minimized by using the Propensity Score Matching method. The results showed that factors affecting farmers’ adoption were training, access to technology, outbreak of plant diseases, and farm size. The future probability of technology adoption would be a rise in the short run, and a fall in the long run. The impacts of technology using the Economic Surplus method showed that over the period of 2006-2014, at the discount rate of 3.50%, the project NPV was 517,392 baht and BCR equaled to 4.82. When the evaluation period was longer into the future, the project NPV increased to 602,439 baht and BCR increased to 5.45. Therefore, the Agricultural Research and Development Organization of Nan province should continue to support the adoption of the technology set, as well as monitor and evaluate the impacts of the technology in order to enhance productivity.
