Abstract

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.

Keywords: maize yield, sloping agricultural lands, terraces.
