A field experiment was conducted at the Agricultural Experiment Center, CMU, Musuan, Bukidnon to (1)evaluate the effects of the different rates of phosphorus on the soil chemical properties at harvest, (2)evaluate effects of the different rates of phosphorus on the growth and yield of adlay, and (3)determine the cost and return analysis of adlay applied with different rates of phosphorus. The field experiment was laid out in a Randomized Complete Block Design with six treatments replicated three times. The treatments used in the study were as follows: treatment 1: 50 kg of N/ha 0 kg of P2O5/ha 15 kg of K2O/ha, treatment 2: 50 kg of N/ha 30 kg of P2O5/ha 15 kg of K2O/ha, treatment 3: 50 kg of N/ha 60 kg of P2O5/ha 15 kg of K2O/ha, treatment 4: 50 kg of N/ha 80 kg of P2O5/ha 15 kg of K2O/ha, treatment 5: 50 kg of N/ha 100 kg of P2O5/ha 15 kg of K2O/ha and treatment 6: 50 kg of N/ha 120 kg of P2O5/ha 15 kg of K2O/ha. Results of the study shows that the soil chemical properties such as pH, exchangeable P and extractable K was not affected by the different rates of phosphorus, however, the soil organic matter content was significantly affected by the treatments. Number of productive tillers and grain yield both increases with the application of 50-80-15 kg N-P2O5 and K2O/ha. Cost and return analysis shows that treatment applied with 50-60-15 kg of N-P2O5 and K2O/ha obtained the highest return on investment thus the most economical among the six treatments.
