The aims of this research was to obtain theprecise balance between NPK organic feritizer and NPK anorganic fertilizer in cultivation sweet corn in regosol. The research was conducted using a single factor experimental method with arranged in a Complete Randomize Design. The treatment was the balance of the dose of organic NPK fertilizer and anorganic fertilizer consisting of 6 levels, i.e, 100% NPK anorganic + 0% NPK organic; 80% NPK anorganic + 20% NPK organic; 60% NPK anorganic + 40% NPK organic; 40% NPK anorganic + 60% NPK organic;20% NPK anorganic + 80% NPK organic; and 0% NPK anorganic + 100% NPK organic. The results of this research showed that all treatments were the precise balances to applied in sweet corn. NPK organic fertilizer was able to replace NPK anorganic fertilizer up to 100 %.
