Drought events are predicted to increase with rising global temperatures and altered rainfall patterns. It is important that agronomists investigate ways to maximize water use to help reduce grain yield losses from drought events. If Ohio corn yields had been reduced 10% in 2013 due to drought, then the economic loss for growers would have exceeded $250 million.
Ohio producers have begun using drought-tolerant corn hybrids that were developed for use in the Western Corn Belt to manage for drought events, but limited research has been conducted on these hybrids in the Eastern Corn Belt. Drought tolerance can be thought of as the ability of a plant to produce greater yields under water stress conditions when compared to other plants under the same conditions.
Since growing conditions are very different in Ohio than in the Western Corn Belt, the management practices that maximize grain yield and minimize environmental effects need to be determined for these corn hybrids.… Continue readingRead More »
