The Tampurin is a technique which combine water management system and use of incubated micro organisms, fertilizer and lime. The study was conducted in Bengkalis, Riau, in the 1997/98 planting season, aiming at evaluating the effectiveness of the Tampurin system to increase corn productivity in peat soil. The component of the Tampurin per hectar used in this study were : 200 kg urea, 200 kg SP36, 150 kg KCl, 1 ton dolomite, 10 kg ZnSO4, 10 kg cupri sulphate, 250 kg rice-husk ash and 100 kg chick's manure. The study revealed that although corn (Bisma variety) yield was relatively high (4.5 ton per ha) but the profit was quite low (Rp 135.000 per ha). This was mainly due to the high land herbicides costs which contribute 36 percent of the total production costs
