Impact of controlled drainage on corn yield under varying precipitation patterns: A synthesis of studies across the U.S. Midwest and Southeast Open
Controlled drainage (CD) is a valuable management practice for reducing drainage volume and nutrient loss, but its impact on corn (Zea mays L.) production is not completely understood. The objectives of this study were to investigate the r…

Conditions potentially affecting corn ear formation, yield, and abnormal ears: A review Open
Abnormal ear development in corn ( Zea mays L.) has been reported for more than 100 years. More recently, in 2016, widespread abnormal multiple ears per stalk node (herein termed as multi‐ears), barbell ears, and short husks were reported …

Lengthening of maize maturity time is not a widespread climate change adaptation strategy in the US Midwest Open
Increasing temperatures in the US Midwest are projected to reduce maize yields because warmer temperatures hasten reproductive development and, as a result, shorten the grain fill period. However, there is widespread expectation that farme…
