A field experiment was carried out in the second agricultural station of the College of Agriculture - University of Al-Muthanna in the Al Bandar area (2 km from the city center), during the season (2020-2021) to know the effect of different levels of potassium fertilizer coated and are K0 (without addition), K1 (30 kg.K.H −1 ), K2 (60 kg.K.H −1 ), K3 (90 kg.K.H −1 ) and K4 (120 kg.K.H −1 without coated) On the vesponse of the genotypes of the wheat (Iksad 59, Iranian, Iksad 901, Iksad 133 and Boohooth 22), According to what the process requires of printing to arrange the splinter panels using a design R.C.B.D and three repetitions, As the potash fertilizer treatments were placed in the main panels (Main-plots) While the genotypes were placed in the secondary plates (Sub-plot). The results showed a significant difference between the genotypes in the traits studied as the Iksad 133 genotype superior in the biological yield, while the Iranian genotype was superior in the weight of 1,000 seeds and the harvest index, and as response to potassium fertilizer, The coated treatment has outperformed 30 kg.K.H − 1 The No. grains spike −1 and the weight 1000 seeds. It also excelled in the seed yield, vital yield and harvest index, which averaged reached 8.03 tons H −1 and 18.33 tons H −1 and 43.98 % respectively, while the coated treatment supertor 90 kg.K.H − 1 significantly in the No. of fertile spikes. M 2 . As for the interaction between the two factors, the combination (Iksad 133 x K3) was superior in the No. of fertile spikes, and the combination (Iksad 59 x K4) in the No. of spike grains, while the two combinations superior (Boohooth 22 x K1) and (Iksad 133 x K1) in grain yield, which averaged 9.11 and 9.06 tons ha −1 respectively, and the combination (Iksad 133 x K1) was superior in bio-it give high mea reached 21.27 tons.ha −1 , The combination (Iranian × K2) was superior in the harvest index, It reached 48.75%.
