The University of Arkansas System Division of Agriculture Irrigation Yield Contest was conducted in 2018, 2019, and 2020. The contest was designed to promote better use of irrigation water as well as to record data on water use and water use efficiency for various crops. Unlike yield contests where winners are decided by yield alone, the irrigation contest results are decided by the highest calculated total water use efficiency (WUE) achieved by a producer. The contest consists of 3 categories: corn, rice, and soybeans. All fields entered were required to show a history of irrigation and production on the field. Irrigation water was recorded by using 8-in. and 10-in. portable mechanical flow meters. Rainfall totals were calculated using Farmlogs™. The contest average water use efficiency of 2018–2020 for soybean was 3.2 bu./in. The winning WUEs were 4.37 bu./in. for 2020, 4.31 bu./in. for 2019, and 3.92 bu./in. for 2018. Adoption of Irrigation Water Management (IWM) practices such as Computerized Hole Selection (CHS), surge irrigation, soil moisture sensors are increasing. Soybean contest participants from 2018–2020 reported using on average 8.9 ac-in./ac of irrigation. [ABSTRACT FROM AUTHOR] |
