The study was conducted at the experimental area of DA-SMIARC-ROS for Crops, Tupi, South Cotabato [Philippines] from June 1997 to February 1999 (two wet and two dry seasons). Results during the two wet and two dry cropping seasons revealed that there was no significant difference on the yield and other agroclimatic parameters among the six organic fertilizers applied namely: Bioearth, Sea Crop, Phela Resource Organica 2000, VMC, and Buhay Lupa following the manufacturer's recommended rate. The average yield for wet season crop ranged from 5.13 to 5.90 t/ha, while that from the dry season ranged from 5.04 to 5.71 t/ha. Other agronomic characters such as weight of fresh ear, number of ear harvested, stand count per plot (7.5 sq m), plant height, and ear height were not significantly affected by the application of different organic fertilizers. Also, the plants were moderately resistant to cornborer damage. The partial budget analyses revealed that the application of inorganic fertilizer based on soil analysis (90-30-30 NPK kg/ha) gave the lowest treatment cost of P2,651/ha compared to other treatments which reached up to P5,445. This was because there was still a need to apply inorganic fertilizers which added to the cost. It was observed that there was slight difference in terms of net benefit among treatments
