Poly Pipe Tubing is widely used in the Mississippi Delta for supplemental irrigation of crops during the growing season. Computerized Hole Selection (CHS) is a tool used to create a prescriptive hole punching map to manage flow and minimize tail-water runoff. Some producers have documented that CHS does not work on their farm. The common thought of failure in poly pipe tubing is the rupturing or splitting of the tubing. This research was based on the thought that failure occurs before the tubing is ruptured and is caused by over pressurization during an irrigation event. Static testing revealed that there are tensile material property differences between different thicknesses of tubing. Dynamic testing revealed on small single hole sections of tubing that hole flow increases once yield tensile strength has been surpassed for all thicknesses of tubing. Therefore, this shows that over pressurization could be the cause for CHS not working on some producers’ field.

The expanding irrigated acreage in the Mississippi Delta has resulted in increased withdrawals that exceed the recharge rate of the Mississippi River Valley Alluvial Aquifer (MRVAA), leading to a decline in water levels. This trend poses a threat of rapid depletion, potentially resulting in deteriorating water quality and increased pumping costs in the region. Water-conserving irrigation practices are a key component to any potential solution, promising enhanced water use efficiency and sustainable agricultural practices. Nonetheless, farmers adopt these practices at different times. This study used a duration model to identify the factors that influence the timing of adoption of computerized hole selection (CHS) and center pivot (CP) practices. We found that farmers who attended extension meetings and held the belief that CHS would lower their input costs adopted it more promptly. Also, participation in conservation programs facilitated the quicker adoption of CP. Conversely, greater farming experience and a higher cumulative number of adopters were associated with slower adoption times for both CHS and CP.
