As part of the promotion on the use of Carrageenan Plant Growth Promoter (CPGP), the Department of Science and Technology – CALABARZON (DOST-CALABARZON) with the Department of Agriculture Regional Field Office IV-A (DA RFO IV-A), DOST-Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD), DOST-Philippine Nuclear Research Institute (DOST-PNRI), and University of the Philippines Los Baños – National Crop Protection Center (UPLB-NCPC) held a Farmers’ Field Day for the farmers from Tanay, Pililla, and Jalajala last November 16 at DA-Rizal Agricultural Research and Experiment Station (DA-RARES), Brgy. Cuyambay, Tanay, Rizal.


The program started with a field walk to show the farmers and guests the results of the experiment conducted by DA-RARES on the difference between rice fields applied with and without CPGP. A 20% yield increase, or 12 cavans, was observed after applying full Recommended Rate of Granular Fertilizer (RRG) and carrageenan PGP compared to 10 cavans when RRG was applied only.

Engr. Elmer Ferry, DA-CALABARZON Research and Regulations RTD, welcomed the guests and participants. A series of short discussions followed to inform more the participants, especially the farmers, about the effect of CPGP on rice fields. Mr. Angelito Carpio, DOST-PCAARRD Crops Research Division Senior SRS, gave a short introduction about the project; Dr. Lucille Abad, DOST-PNRI Atomic Research Division Chief, discussed the carrageenan technology for rice farming; and Mr. Glenn Tabasa, one of the researchers from DA-RARES, presented the results of field demo for dry season 2018.

Ms. Marissa Penuñar, farmer from Tanay, and Mr. Oscar Ledesma, farmer from Pililla, shared their testimonials as one of the carrageenan beneficiaries. They said that the carrageenan increased their yield, produced stronger and thicker tillers, and fastly recovered from pest infection.

DOST-CALABARZON Regional Director Alexander Madrigal and DA RFO IV-A Regional Executive Director Arnel De Mesa were also present during this event. In his message, Dr. Madrigal thanked the project partners and that DOST will always help in adding value to the production and processing. Being an agriculturist, he mentioned the important yield components to be considered and as a farmer also, he shared his testimonial on the effect of using carrageenan to his own farm. “Mechanization will improve productivity and believing in technology will help in solving our problems”, he added. Engr. De Mesa stated several projects done by the DA to further help the farmers in their production such as rice tariffication bill, geo-tagging technology, and loan with low interest rate and no collateral. As a technology promoter himself, he believes that technology such as the CPGP will improve productivity.

A ceremonial turnover of carrageenan to Palaypalay Maunlad Farmers Association, Inc. as the project beneficiary was done afterwards. The farmers will be able to spray carrageenan to a one-hectare field for one cropping season.

Mr. Fernando Ablaza, DOST PSTC Rizal Provincial Director, closed the program and hopes that this project will continue to help more farmers in the future.
