This primarily agricultural province is the rice and corn granary of Luzon due to its plain and rolling terrain. In 2012, the province was declared as the country's top producer of corn with 1,209,524 metric tons.[7] Isabela was also declared the second-largest rice producer in the Philippines and the Queen Province of the North.[8][9][10]
The province has four trade centers in the cities of Ilagan, Cauayan, Santiago and the municipality of Roxas. Santiago is considered to have the fastest-growing local economy in the entire Philippines.[11]
