This summer corn growers in west central and southwestern Minnesota noticed a high percentage of barren stalks and abnormal ear development in some fields. Corn growers and local seedsmen reported 30-40 percent barren stalks in some fields. We surveyed multiple locations for barren stalks in fields along a 50-mile path from Bunde to Madison. The fields surveyed were variety demonstration trials where hybrids from different companies could be compared side-by-side under similar field and environmental conditions. The highest percent of barren stalks observed in the survey was 17 percent; not as high as observed in some commercial fields in the same area. The occurrence of barren stalks was not limited to any particular company's hybrids.

Heat accumulation during the growing season can be used as a predictor of plant development. The very high temperatures we've had, especially the high night temperatures, have caused the Growing Degree Day accumulation to be slightly ahead of normal for most of the state. But corn development is still lagging so there is the question of how effective this temperature accumulation really is for corn development.

For the past three years we have had excellent field conditions for early and timely corn and soybean planting in Minnesota. Conditions are such now that this season will be later, but still could be an "average" or "normal" planting season, especially for soybeans. For a reminder of what's normal, the average corn planting date is May 6; it's May 18 for soybeans. If field-drying conditions exist for the next several days, both crops could be planted in the normal timeframe.
