Agropolitan program, leads by increasing maize production, has been promoted in Gorontalo. Such effort requires, among others, study on spatial land suitability. The objectives of this study were to determine land suitability for maize in Limboto Basin and to spatially present the quality of land units to the plant (maize) requirements. Farmer perception on maize cultivation is also generated. Standard field and laboratory procedures have been performed to characterize land suitability for maize. Besides, geographical information system has been employed to delineated the spatial availability. Among 35,594 ha evaluated area in Limboto Basin Gorontalo, 21,233 ha is categorized as fairly suitable for maize while 14,361 ha is classified as marginally suitable for maize. Majority of the observed farmers were in favor to cultivate maize on their farmland.

In Indonesia, convertion of fertile agricultural lands into, among others, industrial and residential areas has triggered more intensive and extensive exploitation of marginal-and deforested-sloping lands. In Gorontalo province, about one-fifth of sloping forested area has been deforested and converted to upland agriculture or abandoned as schrubs, bushes, and bare lands. This study demonstrates the benefit of using terrace and manure in sustaining maize yield and land productivity as well as reducing soil erosion of cultivated sloping land. It was revealed that maize height, leaf number, kernel number and weight at terrace plot were higher than that of control. Broader variability's of the observed vegetative and generative variables were also identified at terrace plot.
