Four tillage practices and five methods of application of 16-20-0 fertilizer at the rate of 75 kilograms per rai including broadcast and different methods of banding were investigated at the National Corn and Sorghum Research Center. The experimental site had no nutsedge and Burmese grass problem. Zero tillage caused corn plants flower earlier than conventional tillage practice. More plants per units land area were recorded for a conventional tillage system in comparison to minimum and zero tillages. However, plant height and grain yield were not different among the four tillage systems. Methods of fertilizer aspplication failed to show a significant difference being recorded.
