Abstract
ABSTRACT LIMITED tillage and no-till management of continuous irrigated sorghum was evaluated on wide beds separated by 1.5-m spaced water furrows in the Southern Great Plains. No-till beds, no-till beds with furrows ripped, sweep-undercut, and conventional chisel-disk tillage were compared. Glyphosate, a systemic herbicide applied before planting, successfully controlled volunteer sorghum on no-till bed treatments. A double-disk opener planter with coulters and a staggered double-disk opener planter successfully operated through plant residues in 0.75-m spaced rows on the wide beds and penetrated the relatively hard soil surface to open a seed slot on the no-till bed treatments. Conventionally tilled sorghum averaged 5% less grain yield and 14% less water use efficiency than did other treatments. Fuel energy and time requirements were reduced with limited and no-tillage, however no-till costs were higher than with conventional or limited tillage. The limited (sweep) tillage treatment had the lowest labor and fuel energy cost; being $12.00, $17.00, and $8.50/ha less than no-till beds, no-till beds furrow ripped, and conventional tillage, respectively....
