Every agronomist and farmer knows the connection between timely planting and crop yields. The Ohio Agronomy Guide has a recommended Ohio corn plant date range of April 15 to May 10 for northern and April 10 to May 10 for southern regions. Recommended soybean planting is a similar timeframe. RELATIVE grain yield potential is indeed reduced after May 1. However, we need to remember more factors than planting date influence ACTUAL YIELD at harvest. Soil conditions at and after planting are more important than the calendar date to answer when to start planting.
At the Conservation Tillage and Technology Conference (CTTC), we had research agronomists from around the Midwest share their research on planting date and management interactions. Dan Quinn, Purdue Corn Agronomist, shared these corn planting observations. 1) Early planting favors higher yields but are no guarantee. 2) Statewide averages for planting date and yield are not strongly related.… Continue readingRead More »
