There are 4 primary irrigation regimes being examined at various locations

1.  Sprinkler Irrigation - Objectives

• Determine economic impacts of irrigation methods (pre-harvest and post-harvest) in constrained and unconstrained water scenarios.
• Examine profitability of cropping systems (short and long term). 
• Determine optimal amounts of water to maximize yields and profits of selected crops for conventional and conservation tillage systems.
• Identify the most profitable tillage system for a multi-crop system.

         

2.  Subsurface Drip Irrigation - Objective and Research Variables

Determine long term yield, quality, and economic return of peanut when irrigated with subsurface drip irrigation.

       

Research Variables

• Crop rotation
• Drip tube lateral spacing 
• Irrigation strategies 
• Fertilizer practices 
• Row orientation / Seeding rate 
• Tillage practices 

3.  Surface Drip Irrigation - Objectives and Research Variables

• Develop and transfer a simple, affordable, and profitable surface drip irrigation system into peanut production. 
• Determine the short and long term yield, quality, and economic return of a simple surface drip irrigation.

Research Variables 

• Crop rotation
• Lateral spacing
• Strip/no tillage
• Crop row orientation
• Drip tube longevity
• New and emerging crops
• Economic considerations
• Drip tube removal

4.  Non-irrigated - Objectives and Research Variables

• Optimize seeding rate and planting pattern to maximize net farm income 
• Determine best peanut variety, rotation sequence, and cultural practice input level to maximize net farm income. 

Research Variables 

• Crop rotation
• Input levels
• Peanut varieties
• Row orientation
• Seeding rates
