Abstract

In continuous crops of dryland sorghum, propazine at 2.2 kg/ha eliminated one tillage and one cultivation operation during the crop year. At least one tillage operation was required to control volunteer sorghum before planting. In a wheat-sorghum-fallow cropping sequence, propazine at 2.2 kg/ha applied immediately after wheat harvest eliminated three tillage operations during the fallow period after wheat and one cultivation in the sorghum crop. The reduced tillage did not conserve extra wheat stubble for wind erosion control during the winter months. Diuron at 1.1 kg/ha applied in March to sorghum stubble eliminated cotton crop cultivation 2 of 4 years. Considerable sorghum residue was conserved for wind erosion control the winter after cotton harvest when no preplant tillage occurred.
