For many producers, spring planting is late. While everyone is anxious to get a crop planted, corn yield may not be as tied to planting date as we think. In fact, planting into good soil conditions may be just as important as planting date.

|Fig. 2 Corn planting dates and relative yield for Green River area fields. |
For each year, the highest yield was set to 1 and all other yields were adjusted.
Highest actual yield was 233 bu/A in 2011.

The data is the same as in Fig 1.
Here, it is separated by year.
While planting date is important, it probably is less important than planting into good soil conditions and it is certainly much less important than July rainfall.
