Abstract

This study was carried out to alluvial landform of Tolongio Main Garden of Gorontalo Utara Regency of Gorontalo Province, at Agriculture Technology Laboratory of Agriculture Faculty, Gorontalo State University. Thr objective of this research was to determine the effect of Pelangi fertillizing on the production parameters and also to conduct the best dosage to obtain good responses on the production parameters of corn od Lamuru FM, Bisi-2 and Motor variety.The plot were arranged in a block design of split plot which where variety was a main plot with three treatments are Lamuru FM (V1), Bisi 2 (V2) and Motor (V3), while Pelangi fertilizer as a sub plot with fourth treatments are 0 kg/ha (PO0), 75 kg/ha (PO1), 150 kg/ha (PO2), 225 kg/ha (PO3) by three replications.This study showed that fertilizing Pelangi have significantly effect on the production parameters are plant age polination and grain weight of corn, however it was not significant on the plant heigth of corn. The recommended dosage and variety were 225 kg/ha (PO3) and Lamuru FM for production of corn, respectively.

Keywords: Alluvial, corn, production, fertilizing, optimum.
