            The study aimed to develop and assess a testing method for sweet corn production, utilizing plant models in Pathum thani province. The objective was to Enhance Efficiency of Sweet Corn in Pathum Thani Province. The research was conducted from January 2023 to March 2023 in Pathum thani province. Develop sweet corn production technology by crop model. Simulate sweet corn production to evaluate yield under different management condition. Various management conditions were explored, and key factors were analyzed using decision tree model techniques to identify efficient sweet corn production technologies. The identified technology set was evaluated for convenience of management and suitability for the area. Subsequently, the utilization of nitrogen chemical fertilizer increased 25 percent determined by soil analysis values. Phosphorus and potassium chemical fertilizers determined by soil analysis values was tested. In January, planting densities of 8,500 plants per rai with the Hybrix 72 variety. Therefore, test the technology with 10 farmers were compared against the farmers' conventional approach, utilizing of chemical fertilizer according to farmers' methods, planting date, sweet corn population. and the varieties are the same as the testing methods. Analysis of the technology test results revealed no significant statistical variance in corn yield. The testing method yielded an average weight of 4,350 kilograms per rai, while the farmers' method yielded 4,201 kilograms per rai. Although the testing method resulted in a lower corn yield compared to the farmers' method, with a decrease of 149 kilograms per rai (3.54 percent). The testing method also showed a lower cost of production at 5,890 baht per rai compared to the farmers' method at 7,680 baht per rai, representing an 30.39 percent reduction. Despite the lower yield in the testing method yielded a higher income of 21,753 baht per rai, compared to the farmers' method, indicating an increase of 3.55 percent. Furthermore, (DOA) the testing method demonstrated a higher net income of 15,863 baht per rai, reflecting a 19.03 percent increase over the farmer's method. The income-to-investment ratio (BCR) for the testing method was calculated at 3.82, whereas the farmer's method yielded a BCR of 2.78. These results suggest that the testing method offers a higher return on investment compared to the farmer's method, making it a more financially viable option.
