Abstract: This research aimed to examine and evaluate efficiency of a model of disseminating knowledge of correcting salty soil conditions in northeast Thailand. The sample consisted of 40 farmers at Ban Du Yai and Ban Knam Rian, Tambon Mueang Phia, Amphoe Bab Phai, Khon kaen Province, obtained using the purposive sampling technique according to the established requirements for selecting farmers. The instruments used in this research were a test of knowledge and understanding of salty soil problems and correcting salty soil conditions, a scale on attitude toward correcting salty soil and an interview form on salty soil condition correcting behavior. The collected data were analyzed using basic statistics, E1/E2, E.I. and t-test (dependent samples). The research results revealed that the model of disseminating knowledge of correcting salty soil conditions in northeast Thailand had an efficiency (E1/E2) of 82.75/83.00 and an Effectiveness Index (E.I.) of 0.6909. The farmers participating in the project for dissemination inereased their knowledge and understanding of correcting salty soil conditions, positive attitudes toward correcting salty soils and correcting salty soil condition behavior after dissemination at 0.05.
