Triticum AesttivumMusaS. AbedEl-MaliAhmedA. AbbasAl-TayyarA field experiment was carried out in one of the fields of Taza district in Kirkuk Governorate for the agricultural season 2022-2023 in order to determine the effect of soaking wheat seeds with gibberellic acid and foliar spraying with boron at three levels of each and the interaction between them on some growth characteristics, yield and yield components of bread wheat Triticum aesttivum L, research category. 22 A completely randomized block design R.C.B.D was used, with three replications, which included soaking concentrations with gibberellic acid 100, 50, and 0.0 mg GA3. Liter -1 Boron spray concentrations 300, 150, and 0.0 mg B. L-1. The results showed significant differences when treated with soaking at a concentration of 50 mg GA3. L-1 in the characteristics of the number of branches 373.11 branches.m-2, the height of the plant 101.13 cm, the duration of seed filling 46.80, the weight of a thousand seeds 46.32 grams per day, and the grain yield 6.25 tons.h-1. While the concentration exceeded 100 mg GA3. Liter -1  in the two characteristics of the chlorophyll content in the leaf 26.53 CCI and the protein percentage 12.27%. The level of spraying with boron exceeded 150 mg B. L-1 in the characteristics of grain filling time 46.54 days, weight of 1000 grains 46.36 grams, grain yield 6.03 tonse1- and protein percentage 11.76%. The combination of the binary interaction between gibberellic acid and the boron element 50 mg GA3.L--1 and 150 mg B.L-1 was distinguished from the rest of the combinations by giving it the highest averages in the number of branches 395.98 branches m2-, the height of the plant 103.13 cm, and the duration of seed filling 48.74.  day, the weight of 1000 grains is 48.94 grams, and the grain yield is 6.96 tons.ha-1.
