Abstract: This study was conducted to know the effect of added nitrogen and zinc interaction and their use efficiency on their uptake and the yield of wheat in two different texture soils.The study included an experiment (planting in plastic pots) in which five N levels of 0, 100, 200, 300, and 400 kg N ha -1 ; five Zn levels of 0, 10, 20, 30, and 40 kg Zn ha -1 and two soils, clay loam (S1) and Sandy (S2), were used.Wheat plant (Triticum aestivum L.) was used as a plant indicator.A factorial experiment, according to Complete Randomized Block Design (CRBD) with three replicates, was used.The level 100 kg N ha -1 showed higher straw, grain yield, and N use efficiency of 19.15, 15.89 g pot -1 , and 60.40%, respectively.The level 20 kg Zn ha -1 gave higher straw and grain yield of 14.99 and 26.82 g pot -1 , respectively, while the level 40 kg Zn ha -1 gave a higher Zn use efficiency of 1.50%.The clay loam soil showed a superiority of increasing the plant indicators compared with the sandy soil.The interaction of N and Zn had a significant effect on all plant indicators, the interaction treatment (200 N and 20 Zn) had a higher N and Zn use efficiency.A significant correlation relationship (quadratic equation) had been found between the added N and Zn levels with all plant indicators.
