Agronomy Journal 108:473–486 (2016). doi:10.2134/agronj15.0314 Two sentences in the second paragraph of page 481 (left column) have been corrected below. Appearance of singlecross hybrids introduced in 1990s increased genetic yield gain to 0.11 Mg ha−1 yr−1 (Duvick, 1997). For the hybrids from the 1960s through 2000s in our study, GY increase (YAONR) was 0.13 Mg ha−1 yr−1, and GY N response (YAONR minus GY with no N applied) 0.091 Mg ha−1 yr−1. — Krishna P.
