1967
Davis, R. G. | Johnson, W. C. | Wood, F. O.
The spatial extent of the root systems of Xanthium Pennsylvanicum Wallr. (cocklebur), Tribulus terrestris L. (puncturevine), Kochia scoparia (L.) Schrad. (kochia), Digitarius sanquinalls (L.) Scop. (large crabgrass), Solanum rostratum Dunal. (buffalobur), Salsola kali L. var. tenuifolia Tauch (Russian thistle), Amaranthis retroflexus L. (redroot pigweed), and sorghum was determined at 10 weeks after transplanting and at maturity by digging and exposing the roots. The plants were grown without competition under favorable moisture conditions. At maturity, the root profile areas varied from 5.20 m² for pigweed to 17.93 m² for cocklebur. Plants within the extremes in increasing order of root profile area were sorghum, Russian thistle, buffalobur, crabgrass, kochia, and puncturevine.
