Abstract

The study was conducted to evaluate the recommendations provided by Rice Crop Manager (RCM) in comparison with Farmer?s Practice (FP) in Sta. Cruz, Laguna. Four lowland rice areas were selected and monitored for two cropping seasons. An interview was conducted to identify the fertilizer and pesticide use in each site. Soil physical and chemical properties were determined. Suitability analysis for each site revealed that sites 2, 3, and 4 were all moderately suitable while Site 1 was marginally suitable for irrigated lowland rice production. Productivity of the sites was evaluated based on grain yield while profitability was assessed based on return on investment (ROI). During 2015 WS, grain yields were higher with FP than RCM in Sites 1, 3 and 4 while during 2015-2016 dry season grain yields were higher with RCM than FP in all sites. Higher grain yields were supported by higher NPK uptake. Considering profitability, RCM increased ROI from 1.31 to 1.92 and net income of farmer by P28, 935 in Site 1 during 2015-2016 DS. The impact of RCM on yield and ROI was more apparent after two cropping seasons thus it has the potential of increasing productivity and profitability of irrigated lowland rice in Sta. Cruz, Laguna.
