This study objective was to determine the dose of organic and inorganic fertilizers which can increase N, P and K nutrients uptake as well as the growth and yield of sweet corn on inceptisol soil of lowland swamp. Inceptisol soil has low soil fertility and relatively low to moderate levels of organic matter content. Application of organic fertilizer on inceptisol soil of lowland swampis expected capable to increase N, P and K nutrients as well as yield of sweet corn. This research was conducted from April to July 2014 at Experimental Farm Area of Pulau Semambu Village, Indralaya Utara Subdistrict, Ogan Ilir District, South Sumatra Province. The method used in this research was randomized block design consisting treatments as follows: 75% inorganic fertilizer + 5 ton.ha−1organic fertilizer, 50% inorganic fertilizer + 5 ton.ha−1organic fertilizer, 25% inorganic fertilizer + 5 ton.ha−1 organic fertilizer, 0% inorganic fertilizer + 5 ton.ha−1organic fertilizer with six replications. The recommended dose of inorganic fertilizerswas 200 kg.ha−1 urea, 100 kg.ha−1 SP-36 and 100 kg. ha−1 KCl. The results showed that treatment of 75% of inorganic fertilizer + 5 ton.ha−1organic fertilizer had produced N, P and K nutrients uptake with magnitude of 1.850, 0.418 and 2.374 g.plant−1 respectively as well as good growth and yield of sweet corn with magnitude of 356.36 g. plant−1or 15.21 ton ha−1.
