Abstract
Limited tillage and no-till management of 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-disc tillage were compared. Direct drilling was successfully carried out using a double-disc drill with coulters, after application of glyphosate. 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 but no-till costs were higher than with conventional or limited tillage. The limited (sweep) tillage treatment had the lowest labour 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.
