Maize Irrigation Study, 1980, Georgia Coastal Plain
Study:

Research Objectives:

    1. Evaluate ability of a crop growth model to predict when to irrigate.
    2. Evaluate ability of a simple fixed irrigation schedule to meet water needs of corn.
    3. Determine the crop growth coefficients for late corn.
    4. Allow comparison of crop growth characteristics of early and late planted corn.
Treatments:
 1.Irrigate according to the Lambert (Clemson) model using weather data observed at the site.
 2.Irrigate according to tensiometers at the 15 & 30 cm depths at 30 cb of suction.
 3.Irrigate according to a fixed 6 day schedule.
 4.No irrigation.

Basic Crop Management: PLANTED - 30 Jul 1980; EMERGENCE - 04 Aug 1980; HARVEST - ; 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.
