Anco Comments Planting SC Peanut Notes No. 46 2020

— Written By

Cooler temperatures coming are making planting during next week more favorable overall compared to the end of this week to protect peanut crops. We have been having soil temperatures in SC warm up into the upper 60s and lower 70s which helps, but planting into warmer soils next week with a warmer outlooks ahead should help remove uncertainty and provide better growing conditions overall, provided moisture doesn’t cut off. Drs. Monfort (attached and copied) and Jordan (Planting During the Week of May 4 and below) outlined several important points to consider.

Scott Monfort (UGA)

THE MONFORT REPORT – GEORGIA – Soil temps around the state are in the high 60’s to high 70’s. The soil should be buffered from a few hours of cold temperatures during the night time as long as we are warming back in the high 70 to mid-80s during the day. The low 70’s daytime and 50’s night time temperatures for more than 1 to 2 days will drive the soil temps down. With this in mind, I would consider not planting until this cold front has passed. However, I know some growers need to continue planting so please consider the following:

  1. If you are dryland and you are afraid of losing needed moisture then I would go ahead and plant
  2. If you are irrigated, you could hold off until cold front moves out.
  3. If you have questionable seed quality, I would wait to plant until it warms up.
  4. Soil temperatures can be different across the state. (check your county weather stations)
  5. The eastern part of the state will be at more risk than the Southwest part of state.
  6. Freshly turned soil will be colder than normal – let field sit for a day or so to warm up
  7. For strip tillage fields with cover, soils are typically colder than conventional tillage fields so you may want to allow extra time for soils to warm up.
  8. What if I have a lot of acres and need to keep planting or I just want to keep planting.
  9. Make sure you are planting with good quality seed
  10. Add appropriate IF fungicide to help with seedling disease
  11. Do not plant more than 2.5 inches deep
  12. Try not to add irrigation during the coldest days where night time temperatures are in the 40s and 50s and the day time temperatures are below 70-75. Add irrigation to no more than is needed to activate herbicides.
