Abstract

Experiment on tillage systems and methods of weed control in corn was conducted at the National Corn and Sorghum Research Center during July and November 1982. Eight tillage systems varying from zero tillage to conventional tillage were evaluated in combination with three weeding methods, namely, no weeding, hand weeding, and atrazine spraying. The experimental site was heavily infested with nutsedge and Burmese grass. Tillage systems did not have a pronounce effect on plant height, numbers of plant per unit land area, and grain yield. A delay in flowering was observed in a zero tillage plot. Flowering date, plant height and numbers of plant per unit land 'area were not affected by methods of weed control. However, the no-weeding plot yielded less than hand weeding and atrazine spraying plots.

Abstract

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 during August and December 1982. The experimental site had no nutsedge and Burmese grass problem. The result indicated that zero tillage caused corn plants to flower earlier than conventional tillage practice did. More plants per unit 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 four tillage systems. Methods of fertilizer application failed to show a significant difference on all characters being recorded.
