Sugarcane is one of the most promising industry in the Philippines and planted in any land in the country, particularly in Central Mindanao without prior assessment of the land to the crop. Application of an enormous amount of inputs to ensure better production is among common practice even in unsuitable areas. Generation of Land Suitability Index (LSI) in Central Mindanao as a major sugar cane district of Bukidnon province was made to identify the major factor that affects to sugarcane production, using Analytical Hierarchy Process (AHP) and GIS. The study was conducted last September 2015 to February 2016 on the 3 district of Bukidnon. Weights of six performance factors in determining LSI to sugarcane production were established using AHP. Soil depth was the most important among the factors. Utilizing the LSI, land sugarcane suitability maps were generated for the Central Mindanao. The results matched the validation by comparing the results with the actual yields from sugarcane growers, correlation analysis and other relevant data from the Regional Sugar Regulatory Authority. Soil water holding capacity has a significant positive effect on the sugarcane yield while elevation and slope have significant negative effects. Don Carlos, Maramag and Quezon that are extensive sugarcane growing municipalities are highly suitable in the study and actual conditions.
