The article highlights a successful farming model implemented in Quang Ngai, Vietnam, where farmers have switched to cultivating black sesame on 10 hectares of land that was previously unproductive due to water scarcity for rice cultivation during the summer-autumn crop. This model, promoted by the Quang Ngai Agricultural Extension Center, has proven to be economically viable, with black sesame requiring less water and labor compared to rice, and providing higher yields and profits. The article shares the experiences of farmers who have tried the model, detailing the benefits such as higher income per unit area, efficient use of land resources, and the potential for this model to be replicated in other regions with similar conditions.
