Abstract: The Experiment on the Application of Ammonium Phosphate Fertilizer to C-4 Rice Variety was conducted in a lowland rice field in Palangue, Naic, Cavite from June to September 1975. The purpose of the study was to determine the effect of the different rates of Ammonium Phosphate fertilizer on the growth and yield of C-4 variety of rice using the broadcast method. Phosphate with the A 1,800 square meter field was thoroughly plowed and harrowed using the native implements and farm animal. The area was divided into four equal blocks and each block was subdivided into 24 plots/paddies representing five treatments and a control. Treatment 2 applied with 100 kilograms . The application of one-half of the rate of Ammonium Phosphate fertilizer was done at the last harrowing or before transplanting and the final application was made 57 days after planting or at the booting stage. After the field has been thoroughly prepared, trans- planting was done on June 8, 1975. Three to four seedlings were planted at 20 x 20 centimeters apart in the paddies following the planting guide. Two weeks after transplanting, the first weeding was done up to the flowering stage of the plants. Rice Stemborer (Schnoebius incertulas) was the only pest observed and the experiment. The plants were sprayed on July 30, 1975, 45 days after transplanting using Thiodan 4-2 EC. The second and final spraying was done on August 15, 1975, and found to be effective. Fertilized plants grew more vigorously than the unfertilized ones. Generally, the highest average weight of grains was obtained from Treatment 5 to which 250 kilos of Ammonium Phosphate per hectare was applied and produced 0.58 kilogram of palay per square meter of harvest or 145 cavans per hectare. This was followed by Treatment 4 that was applied 200 kilograms of Ammonium Phosphate per hectare with the mean weight of 0.53 kilogram per square meter; Treatment 3 with 150 kilograms per hectare had a mean weight of 0.48 kilogram per hectare and Treatment 1 that was applied with 50 kilogram amorphous produced 0.38 kilo- gram per square meter and Treatment 2 applied with 100 kilogram amorphous produced 0.36 kilogram per square meter while the control obtained the lowest grain yield with TERIMUL RA 0.21 kilogram per square meter.
