This study aimed to determine the growth and production of irrigated lowland rice by using different doses of phosphorus fertilizer. This research was conducted in the form of a 2-factor factorial experiment which was compiled based on a Randomized Block Design (RBD) With the following treatment arrangements: f0 without the use of SP36 (control), f1 SP36 30 kg / ha, f2 SP36 60 kg / ha, f3 SP36 90 kg / ha, f4 SP36 120 kg / ha, f5 SP36 150 kg / ha, f6 SP36 180 kg / ha and f7 SP36 210 kg / ha. The study was conducted with 8 treatments that were repeated 3 times so that there were 24 observation units. The results of this research were, the giving phosphorus fertilizer did not have a significant effect on plant height, number of productive tillers, number of grain / panicle and weight / 1000 seeds. Giving a dose of 180 kg / ha of phosphorus fertilizer could reduce the number of empty seeds / panicles in rice plants. Giving a dose of phosphorus fertilizer of 150 kg / ha could increase the dry weight of the harvest / plot and the dry weight of the harvest / ha of rice plants.
