Drought tolerant corn irrigation optimization in the texas high plains
Research to improve irrigation efficiency in corn cropping by combining drought-tolerant hybrids, variable planting dates, and optimized center pivot nozzle spacing. Field trials evaluate agronomic performance and physiological water stress indicators to support more sustainable water use in arid regions.
Overview
This research initiative focuses on enhancing irrigation efficiency in corn cropping systems by integrating drought-tolerant hybrids, varying planting dates, and optimized center pivot irrigation nozzle configurations. The work addresses challenges associated with declining aquifer resources and increasing drought conditions in the Texas High Plains. Field trials evaluate agronomic responses and physiological water stress indicators, providing insights for sustainable irrigation practices.
Technical specifications
- Drought-tolerant hybrids: Uses drought-tolerant corn hybrids selected for water-scarcity conditions.
- Variable planting dates: Assesses early and late planting impacts on water efficiency.
- Irrigation configuration: Evaluates center pivot nozzle spacing to optimize water delivery.
- Monitoring techniques: Employs capacitance sensors for soil moisture, leaf porometers for stomatal conductance, LI-COR systems for photosynthetic rates, and infiltrometers for infiltration analysis.
- Data analysis: Performs statistical evaluation of crop water stress indicators to inform water use strategies.
Technology readiness level
Currently at TRL 3, with ongoing field trials planned for further validation through a split-plot experiment at an on-farm site. Outcomes are intended to be shared through Texas A&M AgriLife Extension channels to support adoption and scale-up.
