A Case Study of rice straw. The objective was to study the supply chain management of rice straw and develop management guidelines to enhance its value. The study involved interviews with farmers who were members of large rice farming groups that had purchased rice straw balers under the 2021 project to enhance large plots with modern agriculture and market linkage, producing rice in the 2022/23 season and off-season rice in 2023. The study covered 53 plots managed by 159 farmer samples, 25 processors/collectors, and 2 5 users of rice straw in Ubon Ratchathani, Sisaket, Yasothon, Amnat Charoen, and Mukdahan provinces, totaling 209 respondents.
