Abstract

No yield responses to applied Zn occurred on corn (Zea mays L.) at two Prince Edward Island sites where untreated leaf Zn concentrations were 11 to 14 μg g −1 . Both soil- and foliar-applied Zn increased leaf and whole-plant Zn concentrations. Key words: Banded Zn, foliar-applied Zn, corn yield
