KSU Assesses Yield Potential of Drought-Tolerant Corn

By KSU Extension Agronomy

Figure 1. Planting into cold soil (below 50Â°F) when cold conditions are expected for the next 48 hours can lead to germination problems and seedlings not emerging or not emerging well. 1a. Corn seedling that started leafing out below ground and now has twisted leaves which will delay or negate normal plant development.. Figures 1b-c. Unemerged seedlings attempting to leaf out belowground. None of the seedlings shown should be counted as a productive plant.

Distribution of the 1-square-kilometer cells where irrigated land in 2012 exceeded 50 percent of the cell area (blue-green dots) in Nebraska. Pink corresponds to declining annual, while yellow corresponds to declining irrigation-season (May-July) precipitation rates over the 1979-2015 period. The brownish color marks their spatial overlap.
