Moisture was the most important factor influencing the emergence of common bermudagrass ( Cynodon dactylon (L.) Pers.) and weeping lovegrass ( Eragrostis curvula (Schrad.) Nees.) in a clay soil over the range of bulk density and soil water pressure investigated. Both grasses exhibited approximately the same emergence at the −1/3 and −1‐bar soil water pressures. Of those soil strengths and oxygen diffusion rates encountered, none limited seedling emergence of either grass. Small correlation was found between soil strength and seedling emergence.
