Abstract

Under controlled conditions in a growth chamber, emergence of tumblegrass (Schedonnardus paniculatus (Nutt.) Trel.), redroot pigweed (Amaranthus retroflexus L.), and barnyardgrass (Echinochloa crusgalli (L.) Beauv.) was best with an 8-hr night temperature of 65 F and a 16-hr day temperature of 80 F. Other temperature ranges, in order of decreasing effectiveness in stimulating emergence, were 80–95, 50–65, and 35–50 F. Best emergence occurred at the ½-in depth of planting followed by 14, 1, 2, and 4 in. Barnyardgrass was the only weed that emerged appreciably from the 4-in depth. Average emergence was better on a coarse-textured soil than on a fine-textured soil. Under dry soil conditions, emergence was reduced by soil crusting.
