Two field experiments were conducted to evaluate the effects of time of ipil-ipil leaves application on grain yield of IR-36 and IR-42 in a rice field, from January, 1979 to October, 1979. Also, the study was conducted to determine effectiveness of ipil-ipil as organic fertilizer to paddy rice as compared to ammonium sulfate fertilizer. Grain yield of both the test varieties which were fertilized with ipil-ipil leaves were comparable to those fertilized with inorganic fertilizer (ammonium sulfate). Number of panicle per hill of rice plants fertilized with ipil-ipil leaves were comparable to those fertilized with ammonium sulfate. Based on the results, ipil-ipil leaves as organic fertilizer could be applied singly or in split, anytime within three weeks before transplanting and within three weeks after transplanting. Ipil-ipil leaves as organic fertilizer can effectively substitute for the inorganic oil-based fertilizer in paddy rice production.
