Water resources are suffering from scarcity and deterioration their quality due to environmental dilution. Trickle irrigation is the best efficiency systems because it focuses on the root space only, omitting surface runoff and minimizing deep percolation losses. A field study was carried out in clay loam soil in Ramadi city (College of Agriculture- University of Anbar) during the fall season of 2018 using two trickle irrigation systems, mobile system and under surface drip irrigation by using Nano-Root guard drippers. Current study aims to evaluate the physical properties effects, water consumption of bean (cv. Veto) and water use efficiency. for the purpose of comparing the yield of bean irrigated by these two methods. Seeds of bean were sown on 20th of October 2018 and the harvest time was on 13th of March 2019. Evaporation pan was used to estimate the irrigation dates when the depletion of the soil reaches 50% of its water content. Bean productivity significantly increased under surface trickle irrigation with 7.71-ton ha-1 in comparison to 6.32-ton ha- 1 that was obtained from mobile trickle irrigation method. The crop water requirement was 446 mm according to evaporation pan data. Regarding the method of irrigation, they were affected. As a result, the soil water content average for the three replications along growing season was 21.75% under mobile device while it was 24.96% in the sub-surface drip irrigation.
