Abstract

Investigating effective methods in agricultural water management could be a potential solution to address the water scarcity issue and its consequences in the economy of semi-arid regions. A study was conducted in 2023 to identify the benefits of different irrigation technologies and irrigation water management strategies for cotton produc­tion in western Kansas. Effects of two configurations of the new mobile drip irriga­tion (MDI) system (1 gal/h and 2 gal/h) on cotton yield and yield components were compared with a LEPA bubbler and a LESA sprayer to apply 7-day and 14-day irriga­tion interval strategies. This study so far has revealed the superiority of the combination of either a LESA sprayer or MDI-1 gal/h irrigation with 14-day irrigation intervals in achieving the highest cotton yield in the region.
