Rice Crop Manager (RCM) is a web-based decision support tool that extension workers can use to provide farmers with crop management recommendations suited to their specific field conditions. Research trials were establish in actual farmer's field in several municipalities of Agusan del Norte to verify the performance of the recommendations provided by RCM. The ultimate goal of the research is to make RCM better through good science by enhancing the capability of RCM in providing personalized farming advise which matches field specific needs and conditions. Field trials were conducted from 2013-2016 to compare the performance of the existing RCM recommendation (RCM1) with that of the farmers practice (FP) and to further refine and improve the nutrient management component of RCM. A modified RCM recommendation (RCM2) was also included to target alternative yield targets based on season or climate. The results of the research trials were used to improve and upgrade the existing RCM versions. For the five cropping seasons, RCM1 and RCM2 obtained higher yield levels compared with the FP. In season 4 (Jan-Jun 2015), highest yield of 7.2 tons/ha both in RCM1 and RCM2 obtained higher yield levels compared with the FP. In season 4 (Jan-Jun 2015), highest yield of 7.2 tons/ha both in RCM1 and RCM2 were obtained while only 6.5 tons/ha for FP, RCM2 provided consistently greater added net benefit compared to RCM1 and FP from seasons 3 to 6, ranging from Php3,941-11,192/ha. This research project showed that the existing RCM recommendation (RCM1) was successful in increasing the yields and added net benefits of the farmers in Agusan del Norte. Moreover, modification of the recommendations based on alternative yield targets from climate-adjusted yield targeting to application of a new level of N at panicle initiation stage.
