Warm and dry weather has finally arrived and will hopefully continue. Some growers will just be getting started, but for others, their sunflowers have been sitting in the cold, wet ground for 14-21 days. We hear about growing degree days (GDD) a lot with corn, but not as much as sunflowers. How many GDD are actually needed from planting to emergence for sunflowers? Are there any concerns for growers that have had their sunflowers sitting in the soil un-emerged?
The planting crew was on the road again on May 13th and traveled to Colfax, North Dakota. The planter had been worked on over the weekend, so we decided to check the planting depth while at Colfax.
Everyone is eager to be out in the fields and planting this time of year. However, unseasonably cold temperatures and wet conditions have been the theme for much of our area. When we think about planting soybeans, this is one crop that we should probably consider waiting to plant until conditions are more favorable.
