Drip Irrigation Getting Interest Earlier use in arid areas (AZ, west TX, Israel). Efficient use of limited water. Allows injection of fertilizers/other products in root zone. More recently being investigated in humid areas (southeast, mid-south).
Current research efforts in Arkansas using precise water control possible with drip irrigation to investigate irrigation scheduling, rather than investigating the optimal drip irrigated production system.
Seedcotton Yields (lb/acre) Yields not significantly affected by water treatments.
Conclusions from 2001 System/equipment functioning well. Installation of drip tubing (subsoiling every row) in spring, as well as delays in planting and irrigating due to installation probably affected responses in initial season. Drip irrigation system appears to provide desired water control for studying irrigation scheduling.
Acknowledgment Research supported by Arkansas corn and cotton producers through checkoff programs.
