Many corn growers have held the opinion that certain varieties of corn, such as Silvermine, Silver King and Learning, would produce better when grown on poor soils than rich-land varieties, including Reid Yellow Dent and Boone County White. Relative maturity could not account for these differences. They seemed to be connected with a differential ability to produce in the presence of a low mineral nutrient supply. This differential response may be an importance component of the adaptation complex. The first work with inbred lines of corn on differences in functioning at different levels of fertility, was done by Hoffer (11). He found that FI hybrids absorbed less aluminum and iron than their inbred parents. Other work applying directly to the problems considered here is lacking.
