Study aims are to know effectiveness level of SRF-N (D & H) on growth and yield of lowland rice, and gets fertilizer dosage that gave highest yield of lowland rice. Twelve 12 treatments added with recommendation dosage and farmer treatment. Experiment arranged in RCBD three replications. Result: SRF-N significantly effect growth and yield of lowland rice. Applied SRF-N type H with dosage 350 kg per ha which combined SP-36 and KCl gave higher dry grind grain compared to other treatments of SRF.

Treatment of farmer way with dosage Urea 300 kg, SP-36 100 kg, and KCl 50 kg per ha, gave higher dry grind grain (8.14 t DGG per ha) compared to other treatments including recommendation dosage (7.65 t DGG per ha). Effectiveness of SRF-N type H with dosage 350 kg (two times applications) on produce of grain, is 0.97 times compared to recommendation. Need to study more of SRF-H 350 kg and 280 kg per ha, and SRF-H 500 kg per ha (two times application) which combined with P and K recommendation on different location and planting season to obtain accurate data in order to obtain location-specific fertilizer recommendation.
