The soil moisture relationship of European bindweed growing in corn
1939
Bakke, A.L.
Soil samples taken at depths of 1 and 2 feet from corn grownheavily infested with the European bindweed and from ground free of the weed during the summer months of 1933, 1934, and1935 did not show marked differences in their soil moisture content. The bindweed was able to maintain itself when the moisture content was below the wilting coefficient. The deeply penetrating root system was in all probability responsible for the action. Corn does not compete successfully with the European bindweed when the soil moisture content is near the wilting coefficient. A 1-square-rod plat heavily infested with bindweed and planted to corn in 1933 and kept free of bindweed by weekly hoeing produced 33 pounds of corn while the control plat received three cultivations and produced 16 pounds of corn.
