August Peanut Water Requirements

EddieRedding-Cotton-Peanuts 007Since July 25th, the Georgia Weather Station shows no rainfall measured in Dixie, GA. Our 6 month average rain is not bad, but recent dry weather is causing more issues with crops. We have been needing rain for a few weeks now and soil is really dry. UGA Extension Agronomist Dr. Scott Tubbs says whether peanuts were planted in April or June, weather conditions are dry for a critical reproductive development time. Peanuts are setting blooms and filling pods with too less moisture. The majority of the harvestable peanut pods initiate from around 35-40 days after planting through around 90-95 days after planting.

UGA Extension Scientist Dr. Gary Hawkins has this to say about water requirements for August:

The first week of August (if the peanuts were planted by May 1), is the peak of the water use curve, requiring about 2.1 inches per week.  The good news is that we’re about to move past the peak water use period and start requiring less water.  If your peanuts were delayed by 2-4 weeks they will move into the highest water used period soon.  Please see the figure below for the ranges of peanuts planted from late April (yellow) and peanuts planted in middle May (blue).  Hopefully we’ll begin to pick up some more rainfall to help with these water requirements.
