Peanut Irrigation Study, 2002, Georgia Coastal Plain

Yield Comparisons:
Study:

Research Objectives:

    1. Develop irrigation management systems for consistent high yield and quality peanuts for loamy sand soils.
    2. Establish soil water requirements needed for consistent pod development.
    3. Validate peanut irrigation models (especially with respect to restricted irrigation) and evalutate envirocaster and simple Pan scheduling equipment.
Treatments:
 1.High Flow 8 inch depth
 2.High Flow 12 inch depth
 3.High Flow 16 inch depth
 4.Low Flow 8 inch depth
 5.Low Flow 12 inch depth
 6.Low Flow 16 inch depth

Basic Crop Management: PLANTED - 02 May 2002; HARVEST - 12 Sep 2002 ; 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.
