Abstract
The study involves a field experiment that will be conducted at the Ankawa field Directorate of Agricultural Research - Erbil in the growing season of 2021–2022, 10 km to the north of Erbil City (36.2463 N, 43.9931 E, and 420 m above mean sea level). To investigate the effect of three different types of fertilizers (simbio, organic, and chemical) with three different concentration levels (B0 B1 B2, O0 O1 O2, and C0 C1 C2) with three replications. The field experiment consists of 81 plots (27 * 3) using factorial split plot design. The wheat yield ranged from (3.02-5.56 Mg ha-1) the highest yield was in the plot (B2O2C2) and the lowest was in the plot (B0O0C0), moreover, the weight of 1000 gm ranged from (33.48-39.11), the highest and the lowest was the same as the yield plots. The concentration of NPK in the flag leaf of wheat ranged from (2.91-3.99 mg kg-1), (0.11-0.14 mg kg-1), and (1.62-1.82 mg kg-1) respectively.
