Tips to Improve Yield Monitor Accuracy

By Dairyland Seed Agronomy Team

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 a well-established technology that helps producers measure yield variations across fields, influenced by factors like soil, weather, and crop management. By pairing yield data with GPS, these monitors create visual maps that reveal yield trends. When analyzed over several seasons, this data can guide improvements in farming practices to boost productivity and reduce inconsistencies. The Corteva Yield Monitor Pocket Guide offers essential tips for operating and calibrating yield monitors, promoting best practices and helping users avoid common mistakes. 

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. 

The "Tips to Improve Yield Monitor Accuracy" Crop Bulletin reviews guidelines, adapted from Yield Monitor Systems (Darr, 2016), can help maximize yield monitor accuracy in on farm trials.
