A closer look at air and soil temperatures in April and soybean germination and emergence from 10 planting dates did not find chilling injury, despite periods below 50°F. Further research is needed to better understand the imbibitional period in soybean.
Research suggests that staying with a full-season hybrid until late May often provides the best yield. If planting is delayed to late May or early June, consider a medium-season CRM might be considered.
If the first signs of corn emergence (or lack of emergence in some field areas) are causing you concern, follow these steps for assessing the stand and evaluating whether replanting would be advisable.
If you're planning to get an early start on your soybean planting, be sure to check for recommended soil temperatures and the forecast for the coming 48 hours to ensure optimal conditions for achieving good emergence.
Does early planting of corn necessarily result in higher yields? An examination of Nebraska research and data from USDA NASS sheds light on the question, indicating that, up to mid-May, other factors may affect final yield more than planting date.
Planting sets the stage for a successful crop with an even emergence and stand. Consider these tips to help ensure you're providing favorable planting condition via proper soil conditions, planting window, planting depth, and seeding rates.
