Overview

Randomized trial demonstrates efficient irrigation scheduling improves onion yield in semi-arid regions, suggesting sustainable practices.

Key Points

  • The aim is to determine the best irrigation schedules for maximizing onion yield and water efficiency in a semi-arid climate.
  • Conducted over two cropping seasons (2022/23 and 2023/24) in Kombolcha District, Ethiopia.
  • Irrigation treatments included various percentages of ASMDL (60%, 80%, 100%, 120%, 140%) and different intervals for onion growth stages.
  • Water productivity and yield outcomes were statistically analyzed among treatments.
  • Maximum onion yield achieved at 60% ASMDL treatment, with no significant difference compared to 80% ASMDL.
  • Maximum water productivity occurred at 80% ASMDL treatment, followed by 60% ASMDL, with no significant difference observed among treatments 60%, 100%, and 120% ASMDL.
  • Minimum water productivity was found at 140% ASMDL treatment.
