The Department of Agriculture Regional Field Office IV-CALABARZON's Research Division and Research and Experiment Station (RES) play vital roles in the region's agricultural landscape. Post-1991, these entities retained research functions, establishing centers and stations across CALABARZON. Guided by the Agriculture and Fisheries Modernization Act (AFMA) of 1997, they drive mid-stream and downstream agricultural research, aligning with the region's agricultural programs. Over the years, with support from the DA-Bureau of Agricultural Research (DA-BAR), they have developed flagship commodities and promoted proven technological innovations. Through collaborations with various stakeholders, they facilitate the adoption of matured technologies and address location-specific agricultural challenges. The DA RFO IV-CALABARZON is also committed to enhancing collaborations and strengthening linkages with other research institutions to facilitate modernization and technology-based agricultural development in the face of challenges like climate change and urbanization. Collaborations with institutions like the International Rice Research Institute (IRRI) and the Philippine Rice Institute (PhilRice) in digital agriculture initiatives further demonstrate the region's commitment to innovation and sustainability in agriculture.
