Abstract

The objectives of this research were to examine the tacit knowledge of in moina culture with chlorella from successful farmers in Changklang District, Nakhonsithammarat Province and to study the chlorella density including the appropriate period of moina culture from the tacit knowledge. The methodology used in this research was a qualitative research integrated with a quantitative research. This research started with examining the tacit knowledge from successful farmers by using qualitative research design such as selecting the sample witch snowball sampling, collecting information data using an in-depth interview and investigating the data accuracy using a triangulation technique. The second step of this research was testing to confirm the tacit knowledge from successful farmers by a quantitative technique, an experimental design using Completely Randomized Design (CRD), Analysis of Variance (ANOVA) and compared the mean by Duncan multiple range test (DMRT) at 0.05 level significance. The results showed that the chlorella was effective to produce moina. The chlorella culture procedures as follows, day 1 dissolved food materials in green water (namkhieo) with air into 10-20 centimeter level, day 2 stirred the solution in the morning and evening, day 3 added freshwater into 50 centimeter level, day 4 added pure moina and day 5 harvested the products. The average chlorella density confirmed by the farmers was 1.12 x 10⁶ cells per milliliter which produced maximum moina yields in 2 days. In addition, examining the tacit knowledge from the successful farmers can promote the achievement of the practical moina cultivating method, produce maximum yields with the suitable local environment and be developed into a simple technology for farmers in the future.
