Based on the National Weather Service Kenansville forecast, predicted DD-60s for 5 days following planting (if planted today) total 65.5. This translates to very good cotton planting conditions.The DD-60s formula for each day is:
(High Temperature degrees F + Low Temperature degrees F) / 2 – 60 degrees F

Relationship Between Predicted DD-60s & Planting Conditions

Predicted DD-60s For 5 Days Following Planting    Planting Conditions
10 or less                                            very poor

  11-15                                                   poor

                                16-25 marginal

26-50    good
more than 50 very good

Please select windows of opportunity for cotton planting. Review the 5-day weather forecast daily. This approach may mean planting some days and parking the planter other days. Avoid planting cotton if the air temperature is predicted to be below 50 degrees F within 48 hours. Normally, cotton emergence will occur after 50 DD-60s have accumulated (assumes adequate soil moisture).

Note 2014 NCSU Cotton Information pages 19-20. Figure 4-1 reveals NC cotton planting date studies for a 5-year period. This figure notes cotton yields begin to drop below early planting levels approximately 40 days after April 29 (June 11).

Light-colored, coarse-textured soils have dried rapidly. Surface moisture is limited. Please continue to plant cotton 1/2 – 1 inch deep. Planting deeper to find moisture is strongly discouraged.
