บทคัดย่อ (EN): Cassava growers in Thailand are facing with fertilizer application situations on their crop, especially nitrogen (N), phosphorus (P), and potassium (K) chemical fertilizers. With the availability and computability capacity, the interactive web-based approach (iWA) provides a new way for cassava production system information collected on-site to overcome the situations. We have developed a iWA for NPK chemical fertilizer application (iCassFert-NPK) based on soil testing results, planting date, selected cassava variety, and water management options. The web-based structure and architecture of iWA was provided. We designed a total of 25 tables on SQL database on the server to store user's data. The user's data are formatted for the CSM-CROPSIM-Cassava model to simulate the response of cassava to nitrogen fertilizer management, PDSS and KDSS equations were used to estimate the amount of phosphorus and potassium fertilizer application rates. Currently, we have implemented the iWA and registered users can accessed the model simulate the response of three major cassava varieties in Thailand to management decisions in Nakhon Ratchasima province, with approximately 2 million ha of cassava planted area in Thailand. The results show that our web-based interface is well-received by users. However, further research is needed to investigate the improvement of the efficiency of NPK fertilizer application in cassava production system in the area.
