Excerpt from The Influence of Plant Injury and the Root Rot Diseases Upon the Physical and Chemical Composition of Corn Grain In the experiment to determine the effect of breaking the stalks and ear-shanks, yellow dent corn obtained from James R. Holbert of the U. S. Department of Agriculture, was used as seed. It was of PI hybrid material between pure-line strains, and consequently was much more uniform in genetic constitution-than average open-pollinated corn. Seed of this corn was planted on the University South Farm and received the usual cultivation under field conditions.

After summarizing previous experiments pertaining to soil texture, water supply, and nutrient supply on various plants, specifically grains, he details his own experiments on these effects on the root development of maize. The best growth of plant tops was obtained in silt loam with optimum water content; the next best in silt loam with maximum water. Minimum water during both periods produced the greatest absolute weight of roots in loess and the greatest relative weight in silt loam. Maximum water during both periods produced the least absolute weight of roots in loess and the least relative weight in silt loam. It can be said in general by way of conclusion that low water content seems to divert the plant's energies from top growth to root formation. The production of tops and main roots appears to vary directly and the formation of fine branch roots inversely with the water content of soil. An optimum water content seems to favor a relatively high production of main roots, branch roots, and tops.
