An increasing reliance upon yield monitor data to evaluate crop performance and inform management decisions has placed greater importance on ensuring yield data quality.
Yield monitors are capable of providing very accurate estimates of corn yield; however, real-world performance can fall well short of this potential due to lack of proper calibration and other sources of error.
Corn growers often mistakenly correlate test weight (TW) to yield. The two measures are actually only marginally related. Relying too much on test weight can cause growers to over- or under-estimate their yield.
Early frost at harvest can lead to high or uneven moisture, low test weights and increased foreign material, resulting in lower-quality grain that may not store as well. Careful planning and management of drying and storage can help maintain yield when early frost hits.
Corn rootworm larvae begins hatching in late May to June. “Generally, corn rootworm hatch occurs close to the time that we begin seeing lightning bugs outside in the evenings,” said AgVenture Agronomy Lead Louis Sutton. “This is not 100% true, but it gives us a good indication of the hatch timing. When this happens, set a reminder to begin scouting in the next couple of weeks.”
