IT is a common, practice for agronomists to recommend a different variety of a field crop for planting in a soil with a high rather than with a low level of fertility. Usually these recommendations are based upon agronomic characteristics such as resistance to lodging, date of maturity, and other more or less empirical characteristics, but not very often are data available concerning the yield response of different varieties to differing fertilizer applications or fertility levels. Accordingly, in the spring of 1947, a series of experiments were started for the purpose of determining whether or not the malting barley varieties commonly grown in the midwest responded alike to different fertilizer treatments. Response was based on yield. In addition to reporting the results of these experiments, it is also the purpose of this paper to attempt to develop from past literature some scheme to show within which field crop species the varieties are most apt to respond in a similar manner to different fertility levels.
