Peanut Irrigation Study, 1982, Georgia Coastal Plain

Yield Comparisons:
Study:

Research Objective: Determine the influence of seeding rates and row patterns on yield, market quality and value of irrigated and non-irrigated runner peanuts.
Treatments:
 1.Control - Irrigate when tensiometers in 20-30 cm depth exceed 0.3 bar
 2.Irrigate when tensiometers in 45-60 cm depth exceed 0.3 bar
 3.No irrigation

Basic Crop Management: PLANTED - 29 Apr 1982 (rows 0.9m apart, placed 3.81 cm deep); HARVEST - 15 Sep 1982; TILLAGE - Moldboard Plow (30 cm deep plus smoothing and bed shaping), wheel traffic controlled at 1.2 m centers; FERTILIZATION - Typical Extension Recommended Rate; WEED & PEST CONTROL: Typical Extension Recommendations.
