Estimating Reference Evapotranspiration for Irrigation Management in the Texas High Plains
Accurate estimates of daily crop evapotranspiration (ET) are needed for efficient irrigation management in regions where crop water demand exceeds rainfall. Daily grass or alfalfa reference ET values and crop coefficients are widely used to estimate crop water demand. Inaccurate reference ET estimates can hence have a tremendous impact on irrigation costs and the demands on freshwater resources...
متن کاملPerformance of Precision Mobile Drip Irrigation in the Texas High Plains Region
Mobile drip irrigation (MDI) technology adapts driplines to the drop hoses of moving sprinkler systems to apply water as the drip lines are pulled across the field. There is interest in this technology among farmers in the Texas High Plains region to help sustain irrigated agriculture. However, information on the performance of this system and its benefits relative to common sprinkler applicati...

متن کاملOccurrence of cotton herbicides and insecticides in playa lakes of the High Plains of West Texas.
During the summer of 1997, water samples were collected and analyzed for pesticides from 32 playa lakes of the High Plains that receive drainage from both cotton and corn agriculture in West Texas. The major cotton herbicides detected in the water samples were diuron, fluometuron, metolachlor, norflurazon, and prometryn. Atrazine and propazine, corn and sorghum herbicides, were also routinely d...
متن کاملEconomics of Root-Knot Nematode Control on Cotton by DBCP Fumigant on the Texas High Plains.
21 -+ 1 C with a 16-hr photoperiod for 9-14 days. Duration of a test was from start of seed preparation to termination. Seedling growth was determined by fresh weight of roots (blotted to remove moisture), length of tap root, length of longest lateral root, and total number of lateral roots. An estimate of nematode penetration was made by determining the number of specimens which emerged f r o ...
