Abstract

Dry weights of the root systems of 5 oat varieties were determined at 4-inch intervals to a maximum depth of 24 inches. The varieties produced a differential distribution of root dry weight at the various depths sampled. Over 60 percent of the root dry weights of the Corn Belt varieties, Clinton, Marion, and Andrew, was in the upper 4 inches of soil, whereas comparable values for Craigs-afterlea and A465 were 50 percent and 35 percent, respectively. The root dry weight to a depth of 24 inches was the same at the boot stage as at maturity.
