A field experiment was conducted in Al-Habbaniyah district/Al-Khalidiya district/Al-Anbar governorate, western Iraq, in Silty loam soil during the fall season 2020, to study the effect of surface and subsurface drip irrigation and perfusion irrigation with nanotechnology on some international standards to evaluate the performance of the work of irrigation systems after using them in plowed and uncultivated soils. plowed. Perfusion was done when 50% of the prepared water was depleted, the treatments were distributed according to the Nested-Factorial Experiments Design (NFED) with three replications. The yellow corn, cultivar Euphrates, was planted on 15/7/2020. The American evaporation basin, class A, was used in the timing of irrigation. According to the rate of water consumption in terms of the equivalent depth of the added water, the total yield and the efficiency of water use. The results showed giving the best discharge rate, homogeneity coefficient and percentage variation in the system drainage before planting at pressure of 100 kPa, which amounted to 2.27 L hr -1 , 98.91 and 7.69%, respectively, while these parameters decreased after planting and reached the best in the perfusion irrigation system, which amounted to 2.25 L hr -1 , 98.11 and 16.31% at the same operating pressure sequentially, while the lowest amount of these parameters after planting was 1.90 L hr -1 , 90.95 and 41.66% respectively in the surface drip irrigation system under an operating pressure of 50 K Pas.
