The t-test, Borich's needs, and The Locus for Focus Model were analyzed for all young farmers who responded to the questionnaire and for each characteristic (farming type, farming period) of young farmers, and 4-H activities with high priority were derived. As a result of the analysis, first, it was found that 4 of the 5 support areas were prioritized in supporting 4-H activities for youth agriculture. appeared to be in the top 5.

Third, by farming period, in the case of the beginning stage 1. Four tasks (1-1 to 4) were included in the priority list, whereas in the settlement period, only one task (1-2) was given priority. 2. In the case of human network formation and support area, only one task (2-4) appeared as a priority in the initiation period, whereas three tasks (2-1, 2, 4) appeared in the settlement period, showing a difference in priorities. showed Based on these research results, the 4-H Association needs to establish a strategy with the highest priority so that 4-H activities can serve as a legal basis and system to support youth farmer activities and exchanges.
