Corn Response Across Plant Densities and Row Configurations for Different Moisture Environments

Table 7

Spearman’s rank correlation coefficients (R), values, and number of observations (n) between plant height, stover yield, yield, grain N concentration, and aflatoxin values. Upper right cells are for the low-moisture environment; lower left cells are for the moderate-moisture environment.
