AbstractField experiment was conducted in the agricultural fields in Zouayt Sityih / Ramadi / Anbar province, in 2016 - 2017 and 2017- 2018, according to split-plot design by using (R.C.B.D) with three replicates to study the effect of Humic acid on the growth, yield and quality of several genotypes from faba bean, the main plots included three different humic acid concentrations (0, 1.5 and 3) cm3 L-1 while subplots included four genotypes (American, Dutch, Local and Spanish) in both seasons respectively. The results were as follows: The genotype V2 showed the highest plant height of (75.39, 77.32) cm for both seasons respectively. While the genotype V1 gave highest rate of the number of branches plant 9.59 and 10.74 brancheplant-1, the number of pods in the plant reached 12.90 for the first season. The seed yield was 6.15,7.76 ton.h-1. The concentrations of the humic acid were significant in most studied traits. H3 gave the highest seed yield 6.27, 6.95 ton.h-1 in both seasons, while H0 gave the lowest mean 3.12 , 6.27 ton h-1 in both seasons. The interaction between genotypes and concentrations of humic acid was significant in most characters in the 2017-2018 season.
