Rice occupies the largest cultivated area, with 243.85 square kilometres of irrigated area with a yield of 410 t/km², and rainfed rice with an area of about 165.73 km² with a yield of 300 t/km². The province's rice production has the estimated capacity to feed 1,072,456 people—far more than the provinces population. Ironically, rice insufficiency persists, especially in the upland and hard to reach barangays.
Corn plantations cover 255.25 km² for both white and yellow corn with a total production of 55,767 t in 2000 with surplus corn grits of 31,106 MT enough to feed more than 2 million people, four times greater than the province's population.
Banana is another abundant crop covering an area of 127.45 km² and could be seen everywhere but not in conventional plantation form. Banana chips are also processed in the province.
Oil palm plantation covers 118 km². The plantation is a Malaysian-Filipino joint venture, with agrarian reform beneficiaries as land owners. Crude oil is processed in the sites of Rosario, and Trento.
Coconut trees are widespread in the province, covering 393.36 km².
