Boost in Rice Yields Through Use of Seaweed Extracts

Bulacan rice farmers have showed their intention of using carrageenan growth promoter (PGP) in boosting their rice yields. Scientists of the Department of Science and Technology (DOST) have developed PGP and conducted trials in Bulacan, Nueva Ecija, Laguna and Iloilo and these resulted in an increase of 15 – 40% in their rice yields.

 Leonardo Ignacio, a 65-year-old farmer from Bulacan, said that technologies like carrageenan PGP could be very helpful to Filipino farmers like him. “I am interested in carrageenan fertilizer since it is a safer alternative, more usable in small-scale farms, and more affordable,” Ignacio said in Filipino.

Another Bulacan farmer has expressed interest in PGP since his farmlands were affected by Typhoon Nona. He intends to boost his crop yield from his two hectare rice farm that currently has a yield of 56 cavans per harvest season. According to experiments by DOST-Philippine Nuclear Research Institute (PNRI) and Philrice, PGP makes rice plants resistant to natural disasters, increases the size of panicles and promotes hgealthier rice plants as compared to those using commercial fertilizers only.

Currently, the developers of carrageenan PGP are open to expanding its use to other crops like corn, tomato, and other vegetables to the advantage of farmers like Ignacio and Valero, who also plant sitaw, string beans, tomatoes, and okra.

The field testing in Bulacan showed that the application of 9 li/ha of carrageenan PGP in addition to 3 and 6 bags of chemical fertilizer per hectare led to a 65.4% increase in grain weight, and increase in panicle length from 3.5% to 12.5%.

The development of carrageenan PGP is funded by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the DOST. PGPs were distributed to 650 farmers for testing in Pulilan, Bulacan, and will be field tested in 2,000 hectares of rice in the province. In 2015, Department of Agriculture (DA) Secretary Proceso J. Alcala and DOST Secretary Mario Montejo signed a memorandum of agreement to upscale verification testing in Regions 1, 2, 3, 4A, 6, 9, and 11.

Graduate students from Stanford University visited the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD) to learn about mangrove crab production, particularly on soft-shelled crabs, and vermicomposting use and application.

The visit was arranged by the Tuason Development Foundation Program Manager Dickie Soriano, the country partner of Stanford University in implementing the Design for Extreme Affordability Program. The Stanford University students were Jade Fernandez, James Winter, and Jaou Touré. They were joined by the beneficiaries of the Tuason Development Foundation: Cromwell Cuizon, Ian Joune Fernandez, Xarex Gameng, and Roger Jude Garcia.

The Design for Extreme Affordability Program is a multidisciplinary, project-based course which allows students to design a program, immerse in various social issues and challenges in partner countries, and propose a project which offers real solutions.

DOST-PCAARRD Acting Deputy Executive Director Edwin Villar and Policy Coordination and Monitoring Division (PCMD) Director Leah Buendia welcomed the visitors while Agricultural Resources Management Research Division (ARMRD) Director Rodolfo Ilao presented the Council’s Industry Strategic S&T program (ISP), its current programs and initiatives, and information on vermicomposting. On the other hand, DOST-PCAARRD Inland Aquatic Resources Research Division (IARRD) Director Dalisay Fernandez provided an orientation of the Council’s programs and initiatives on inland aquatic resources, narrowing down on mangrove crab. Lastly, Technology Transfer and Promotion Division (TTPD) Director Melvin Carlos discussed the Council’s various modalities for technology transfer.

Aside from the meeting, the students toured Arnold and Paz Organic Farm in Tranca, Bay, Laguna, to provide them a preview of vermicomposting production used in commercial-scale farming.
