GROWTH AND PRODUCTION OF RICE (ORIZA SATIVA L) IRRIGATION FIELD AT VARIOUS DOSAGE OF DIFFERENT PHOSPHORUS FERTILIZER

Abstract

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.
