The experiment on phosphorus fertilization on paddy rice was conducted in Kasang village Padang Pariaman district from August to December 1999 to observe the efficiency of phosphorus on paddy rice. The experiment was designed in a randomized block design with five treatments: 100 kg SP36, 20 kg SP36 (Starter), 50 kg SP36, 20 kg NPK (Starter) and 50 kg SP36 + 600 kg husk ash/ha) and three replications. Results of the experiment showed that phosphorus content at the location was medium (18,18 ppm). Phosphorus application by P-starter (20 kg SP36/ha) is more economical and more benefit over phosphorus application of 100 kg SP36/ha and reduce fertilizer application 80 kg SP36/ha and gave yield of paddy rice 4.236 and 4.320 t/ha respectively
