Recent heatwaves and persistent drought conditions have triggered premature corn death in various regions across the country. This phenomenon can significantly affect corn yields and test weights. Here's what you need to know and how to prepare for a successful harvest:
What to Expect:
• Variability in Grain Moisture and Yield: Prematurely deceased corn crops exhibit a wide range of grain moisture levels, often falling between 20% to 30% or even higher. This variability can pose challenges in drying the corn and may increase the risk of mold and spoilage. Yields can also be substantially reduced, with losses of up to 50% in some cases.
• Reduced Test Weight: Test weight is a crucial measure of corn's weight per bushel. Prematurely deceased corn typically has lower test weights, indicating that more bushels are needed to fill a truck or grain bin. This can potentially reduce the overall value of corn.
How to Prepare:
To navigate the impact of premature corn death effectively, consider the following steps:
• Optimize Combine Settings: Adjust your combine settings to accommodate variable crop conditions. Proper configuration ensures that corn is harvested at the appropriate moisture level, minimizing the risk of mold and spoilage.
• Frequent Yield Monitor Calibration: Maintain the accuracy of your yield data by calibrating your yield monitors regularly. This should be done daily or whenever you switch between different corn hybrids.
• Prioritize Drying and Storage: Given the elevated moisture levels associated with prematurely deceased corn, swift drying and proper storage are essential. Timely action can help prevent mold and spoilage, preserving grain quality.
• Safety Guidelines: Ensure strict adherence to safety guidelines during the corn harvest, especially when operating near power lines.
The impact of premature corn death varies depending on the severity of the drought and the timing of the crop's demise. It is crucial to remain aware of potential challenges and take proactive steps to minimize losses.
Additional Tips:
• Harvest Early: Harvesting corn earlier results in lower moisture content, making it easier to dry and store.
• Pre-Harvest Inspection: Examine the corn for signs of premature death, such as yellowing leaves or shriveled kernels.
• Combine Adjustments: Consider adjusting combine settings to account for the lower moisture content of the corn.
• Thorough Drying: Ensure the corn is dried to a moisture content of 15% or less before storage.
• Proper Storage: Store the corn in a cool, dry location to maintain its quality.
By following these guidelines and tips, you can minimize losses caused by premature corn death and optimize your harvest during challenging conditions.
