Technical Abstract: Precision mobile drip irrigation (PMDI) is a technology that was developed in the 1970s that converts drop hoses on moving irrigation systems to dripline. Although this technology was developed more than 40 years ago, it was not widely implemented and few studies reported on its performance. Recently PMDI has been introduced into the Central and Southern High Plains areas as an alternative irrigation system to sprinkler spray, especially in the case of low capacity wells. Materials and installation design for these current systems are different than the early systems. These differences warrant investigation of the new materials and system performance relative to low elevation spray application (LESA) and low energy precision application (LEPA), common application methods for these regions. This presentation will provide an overview of the PMDI system design, installation and the response of a drought tolerant corn hybrid, Pioneer Aquamax P9697AM, compared with LESA and LEPA from the summer of 2015 field study conducted at Bushland, Texas.
