In the fertile fields of the Cagayan Valley, a vibrant revolution is taking root. Long considered a backyard staple or seasonal delicacy, ube (purple yam) is stepping into the spotlight as a primary crop under the High Value Crops Development Program (HVCDP) of the Department of Agriculture Regional Field Office No. 02 (DA RFO 2) and the pooled efforts of the different research centers. Driven by growing market demand and the urge to diversify regional agriculture, research scientists and agricultural extensionists from the different RCES are unlocking the economic potential of this humble tuber turning it into a lucrative commodity for local farming communities in a 100 hectare-plantation in Echague, Isabela.
Breakthroughs in Production and Cultivation
Historically, farmers faced challenges cultivating ube due to seasonal limits, high vulnerability to pests and diseases like anthracnose, and reliance on inconsistent planting materials.
The interventions from DA RFO 2’s HVCDP and the different Research Centers and Experiment Stations (RCES) have addressed these obstacles directly:
• Quality Planting Materials: Researchers are refining tissue culture techniques and mini-tuber production systems. This ensures a steady supply of disease-free, high-yielding ube plantlets, drastically reducing crop failure rates for growers.
• Climate-Resilient Intercropping: DA RFO 02 researchers have developed intercropping systems that integrate ube beneath light canopies or alongside existing seasonal crops. This maximizes land use efficiency, improves soil health, and buffers smallholder farmers against changing weather patterns.
• Standardized Package of Technology (POT): Through comprehensive training programs and production guides, local growers are adopting optimal fertilization strategies, trellising techniques, and post-harvest handling protocols to ensure higher tuber yields and uniform tuber quality.
Unleashing Marketability and Economic Potential
“The surge in global and domestic demand for natural food coloring, traditional desserts (ube halaya, ice cream, pastries), and health-conscious food products has made ube one of the most profitable commodities per hectare in the high-value crop sector,” Ms. Carol Pasion Albay, Regional HVC Philippines and Export said. She explained the significance as:
• High Commercial Value: Unlike traditional staple crops with narrow profit margins, processed and raw ube commands premium pricing in the market. The high dry-matter content and deep purple pigmentation of the varieties propagated at RCES of DA RFO 02 make them particularly attractive to large-scale food processors and commercial bakeries.
• Value-Addition and Processing: DA RFO 2 works closely with local farmers’ cooperatives to encourage value-added processing—such as producing ube powder, purees, and chips. By moving up the supply chain, farming communities capture greater economic returns compared to selling raw tubers alone.
• Securing Local Supply Chains: As food manufacturers previously struggled with national ube shortages, Cagayan Valley’s strategic push positions the region as a major supplier for northern Luzon and Metro Manila markets, establishing a reliable revenue pipeline for participating farm households.
A Sustainable Future for Valley Farmers
Through the focused efforts DA RFO 2’s strategic backing under the HVCDP, ube is evolving from an underutilized crop into a cornerstone of regional agricultural development. By pairing innovative science with strong market linkages, Cagayan Valley’s agricultural sector is proving that the future of farming is not only resilient, but deeply purple.
As advanced propagation techniques and market-driven strategies continue to take root, this humble purple tuber is poised to elevate smallholder livelihoods, fortify regional food supply chains, and transform Cagayan Valley into a premier agricultural hub for high-value crops.
