Abstract: The research was carry out at the experimental garden of Agriculture Faculty, University of Riau. The aim of this research to determine the effect grant of dolomite and N, P, K fertilizers interactions on sweet corn in peat land and get the best treatment.

The data were proceed with analysis of variance and Duncan’s New Multiple Range Test at 5% level. Parameters measured are plant height, stamen appears time, stigma appears time, harvest time, cob diameter, cob length without hust, cob weight without hust/sample.
The result of research shown that giving of Dolomite and N, P, K fertilizers can increase growth and production on sweet corn applications of 4 ton/ha dolomite and N, P, K fertilizers (300 kg/ha Urea + 200 kg/ha SP-36 + 100 kg/ha KCl) give the best effect for cob weight without husk/sample productions on sweet corn in peat land.
