The 2019 annual corn production in the region reached 1.87 million metric tons, the highest production since 2013. Production registered in 2012 at 1.88 million metric tons was still the highest annual output of the region since 2005 and more than nine thousand metric tons higher than the region’s latest estimate. For the past ten years, annual regional corn production moved in erratic pattern with the lowest recorded estimate in 2010 at 1.25 million metric tons and the highest, as pointed out earlier, in 2012. Aside from last year’s production and in 2012, there were other years where annual regional production hit the 1.80 million mark- in 2014 at 1.86 million, in 2015 at 1.80 million and in 2017 at 1.84 million metric tons.


The latest estimate of production in the region is 14.8 percent higher than the 2018 estimate of 1.63 million metric tons, or about 240 thousand metric tons additional production in 2019. Similarly, national corn production estimated in 2019 at 7.98 million metric tons also appreciated by 2.7 percent, or up by about 207 thousand metric tons from the 2018 estimated level of 7.77 million metric tons.

Cagayan Valley’s 2019 corn production posted the largest share in the national production occupying almost one fourth of the country’s total   production. On the other hand, the second largest corn producer in the country, Northern Mindanao region, with estimated 2019 corn production of 1.31 million metric tons contributed only 16.5 percent. ARMM region and SOCCSKSARGEN showed almost identical shares of 14.0 and 13.9 percent, respectively. ARRM region reported an estimated production of 1.11 million metric tons while SOCCSKSARGEN estimated its 2019 corn production at 1.10 million metric tons. Ilocos region landed in the top 5 corn producing    region in the country with its share of 7.2 percent and an estimated corn production in 2019 of more than half million metric tons. The remaining more than one fourth percent were produced from the eleven regions with four regions sharing more than three percent each, two regions with more than two percent share apiece, three regions with more than one percent share each while two regions contributed less than one percent each. Surprisingly, production from these eleven regions totaling 25.1 percent is only 1.7 percentage points higher than the region’s share.

Breaking down the regional production by type of corn produced, more than 98 percent of the Cagayan Valley’s production was classified as yellow corn while less than two percent was tagged as white corn. Indubitably, corn produced in the region were mostly for commercial feed purposes as supported by the figure, while a little portion was devoted for human consumption and mostly harvested as green corn.   

In terms of the type of seeds planted, about 96.5 percent of the total corn production was sourced out from hybrid seeds. The remaining 3.5 percent was harvested from modern OPV and native OPV with the former seed type clinching 3.0 percent. Notably, yellow corn produced in the region was mostly hybrid. A little portion of the hybrid seeds planted was hybrid white corn which is gaining potent the last few years due to its palatability and size compared to native or modern OPV white corn.


More than sixty percent of the regional corn output was produced in Isabela

The largest province in the region contributed the largest share in the regional corn production. About 60.8 percent of the total corn output in the region was produced in Isabela province with an absolute contribution of about 1.14 million metric tons. Cagayan province, the second largest province in the region, is far second with its share of about 26.4 percent or an estimated production in 2019 of less than half million metric tons. The province of Quirino which contributed 8.8 percent placed far third with its estimated corn production of about 165 thousand metric tons. Additionally, Nueva Vizcaya province with its estimated production of about 74 thousand metric tons of corn in 2019 placed fourth in terms of corn producing province in the region and shares about 4.0 percent to the regional output while corn production in Batanes is not significant.


Increase in production attributed largely to increase in area harvested

The increment in corn production for the region in 2019 was due largely to larger area harvested. Last year, more than 427 thousand hectares was reported as area harvested for corn in the region compared with the reported area harvested in 2018 of only more than 385 thousand hectares.   In detail, around 42,090 hectares was added to the 2018 estimated area harvested forming about 10.9 percent increase in area harvested for 2019.

Supplementing the 2019 upward trend in production was also the increment in the reported yield per hectare in 2019 which showed about 0.15 metric tons per hectare accretion or additional 3.0 sacks per hectare increase from the 2019 yield of 3.21 metric tons per hectare.         

Across provinces, Cagayan province reported the largest increase in area harvested in 2019 from its 2018 estimate area harvested of more than 89 thousand to more than 118 thousand hectares last year or 31.8 percent increase giving an absolute value of more than 28 thousand hectares increase. Isabela province also contributed in the regional increase in corn area harvested last year with its 2019 estimated area harvested of almost 253 thousand hectares, about 12 thousand hectares higher than the 2018 estimate of more than 240 thousand hectares. This increment is about 5.3 percent increase for the 2019 corn area harvested in the province. Not to set aside, area harvested for corn in Quirino also posted an increment of about 2.5 percent or from its 2018 reported area harvested of almost 39 thousand hectares to more than 39 thousand hectares last year. The other two provinces posted decrement in its area harvested in 2019.     




On the reported yield per hectare in the provinces, only two provinces reported an increase in its productivity with the province of Isabela nailing the highest increment of 0.26 metric tons per hectare or about 5.2 sacks per hectare from its 2018 yield of 4.23 metric tons per hectare. In the same modest, the province of Cagayan also reported an increase of about 0.05 metric tons per hectare or about one sack per hectare from its 2018 yield of 4.12 hectares per hectare.  (SR-2020-006)

Technical Notes: 


Production refers to the quantity produced and actually harvested for a particular crop duringthe reference period.  For palay and corn, harvest area refers to the actual area harvested/to be harvested during the reference quarter.

Estimates and forecasts of production and harvest area of palay and corn are generated from the Quarterly Palay and Corn Production Survey (PCPS) of which there are four survey rounds in a year, that is, January, April, July and October. The following are the data taken from these surveys: 

1) Production estimates of the previous quarter for each survey round;

2) Forecast one quarter ahead based on the standing crop; and

3) Forecast two quarters ahead based on planting intentions. 


Definition of Terms:

Irrigated - palay area with irrigation facilities that supplies water to the farm through artificial means with gravity, force/power, pumps, etc. it is not confined only to low areas but also to high places where paddies are built for standing rice.

Rainfed - palay area that has dikes that retain water and is solely dependent upon rainfall for its water supply.

Upland - palay area without amenities for standing water. It is not only confined to high places but also to low areas without irrigation.

White Corn - used primarily for human consumption.

Yellow Corn - generally used as feed grain which includes all types of corn other than white.

Yield - is an indicator of productivity derived by dividing the total production by the area harvested.
