in Crop and Soil Sciences, specifically at

• Cultivar management interaction with
agronomic practices
– Eight new runner-type peanut cultivars
released since 2006
• Pest management interaction with
agronomic practices
– New cultivars have various combination of pest
resistance; alter management strategies
• Maturity determination of new cultivars
– Evaluation of adjusted Growing Degree Day
(αGDD) model for peanut
• Since 2006 there have been 8 new
runner-type peanut cultivars released
from UGA (5), UF (2), and USDA (1)
• Four of the eight have significantly
larger seed size than the previous
standard, ‘Georgia Green’
Georgia-06G
Georgia Green
• Issue #1 – The larger seeded cultivars
significantly increase the seed cost per acre
– Previous cultivar standard, Georgia Green, was
sown at ~ 105-110 lbs/acre when planted at
recommended 6 seed per row-foot
– The four large-seeded cultivars are sown at ~
135-140 lbs/acre when planted at 6 seed per
foot
– That extra 30 lbs/acre costs producers about
$30/acre more in seed cost
– Can we reduce the seeding rate of these largeseeded cultivars?
• Seeding rate / plant population trials
were established in cooperation with Dr.
Scott Tubbs
– Evaluate seeding rate adjustment on single
row, twin row, and 30-inch row patterns

• Results
– Three of the four large-seeded cultivars
continued to respond to the 500 lbs/acre
level recommendation for Ca in “pegging
zone”. Georgia-06G continued to gain yield
and grade as level increased.
– Germination response on thermogradient
table indicated our long time
recommendation of planting when soil temp
reached 65° F should be adjusted to 6870° F
• Issue #3 – Maturity determination –
improvement of accuracy, development
of new tools
• Cooperative research and verification
with Dr. Diane Rowland, University of
Florida, and Dr. Wilson Faircloth,
USDA-ARS/Syngenta
• Development of Growing Degree Day
model for peanut
• Evaluate recently released cultivars
• Evaluate new cultivars’ response to early
planting
• Verify maturity range of cultivars
