| Abstract/Contents: | "In the southwestern part of the United States irrigation water for turfgrass has been restricted. Water conservation strategies such as subsurface drip irrigation (SDI) and applying minimal irrigation amounts are proposed and their feasibility needs to be investigated. A study was conducted at New Mexico State University from 2015 to 2018 to investigate the effect of minimal irrigation levels applied from a SDI system on warm-season turfgrass quality. Bermudagrass (Cynodon dactylon L.) cv. Princess 77 and Seashore paspalum (Paspalum vaginatum O.Swartz) cv. Sea Spray was irrigated at either 55, 40, 25 or 10% of reference evapotranspiration for short grass (ETos) from June to November. Turfgrass quality (TQ), percent cover, color and NDVI were recorded monthly during the research period. In 2015, 2016 and 2017 turfgrass irrigated at 40 and 55% ETos resulted in TQ above the acceptable threshold of 6. Plots irrigated at 25 and 10% of ETos exhibited unacceptable quality during the 4 years of study. In 2018 all ETos irrigation levels resulted in turfgrass quality below the acceptable rating of 6. Natural precipitation ranged from 147 mm to 231 mm and these low amounts did not help in maintaining acceptable quality during the 4 years of study. We conclude that three years of cumulative stress and lack of adequate recovery time between stress periods resulted in poor turfgrass performance during the last year of the study." |
