A balanced fertilizer is an effective method for increasing rice production and maintaining environmental sustainability. This study objective was to determine optimum dosage of N, P, K fertilizers for Mayas variety of upland rice. The research was conducted from January to July 2019 on the Leuwikopo Experimental Station of IPB University, Bogor. This work was consisted of three parallel experiments each for N, P, K fertilizer. The treatment was fertilizer dosage, i.e. 0, 50, 100, 150, and 200% of the reference (100% N = 150 kg Urea ha-1, 100% P = 100 kg SP36 ha-1, 100% K = 100 kg KCl ha-1). All treatments were arranged in a randomized complete group design. The results from variables observed are converted to relative yield and a quadratic equation is made to determine the optimum fertilizer dosage for N, P, and K of Mayas upland rice, i.e. 174.79% N, 90.76% P2O5, 77.14% K2O from reference similar to 120.60 kg N, 32.67 kg P2O5, 46.28 kg K2O ha-1 or 261.18 kg urea, 90.76 kg SP36, 77.14 kg KCl ha-1.

Keywords: relative yield, multi nutrient response, recommendation dosage
