16 Green Revolution soil and nutrient management package. The Philippine Masagana 99 packaged and implemented a fertilizer management that also included basal fertilizer application (Box 2; Ferre, 1986). Several studies at IRRI showed that the basal incorporation of fertilizer, done during the last harrowing and puddling prior to transplanting, is more efficient than broadcast. Adoption of the basal application, however, was very low since farmers have been traditionally applying their fertilizers several days after transplanting. However, if basal application is done, fertilizer application at two weeks after transplanting is to be employed.
The Masagana 99 Packaged Technology on Fertilizer Rate and Management Notes: a. Application method: 2/3 N and all P and K were incorporated during the final harrowing. b. 1/3 N 5-7 days before panicle initiation c. Apply ZnSo4 into the soil, in the seedbed or in the paddy field, foliar spray or dipping seedlings in ZnO d. In the upland, no fertilizer application was done. It is suggested that 90 kg N/ha can be applied at 10, 35 and at 65 days after seeding. e. Organic fertilizer is also recommended.
