| Abstract | ||
| A field experiment was carried out during the winter season 2018-2019 at the Agricultural Research and Experiment Station of the Faculty of Agriculture/ University of Kirkuk in the Sayadah region. In order to study the effect of three levels of humic acid (24, 12, 0 kg.h-1), four levels of iron and zinc (60Zn + 80Fe + 60Zn + 80Fe + 0 mg. L-1) and three genotypes of leguminous (local and Spanish) (LOZ DE OTONA) and Italian (FAVA DE ORTO) in the attributes of growth and yield. The experiment applied by design the complete random sectors as a global experiment with three replications. The number of experimental units is (36) experimental units. The study included measuring each of the characteristics (number of days of flowering, plant height and number The branches, the paper area, the number of nodes, the number of pods, the number of seeds in the pod, the length of the pod, and the weight 100 seeds, the individual yield of seeds, the total plant yield and the percentage of protein.) Increased concentrations of humic acid led to significant increases in all growth characteristics, yield, and its components. A concentration (12) was given to the highest yield of the total yield of seeds (4969.2 kg / h-1), individual plant yield (71.26 g), concentration (24) was superior to the leafy area (170.64 cm), and to the number of seeds / pod (4.77 seeds per pod), and the comparison treatment (0) in the number of days of cultivation As it reached (74.94 days), in the description of the length of the pod (18.90 cm), the number of branches (8.11 branches), and the percentage of protein (25.36%). As for the concentration level (Zn60 + Fe80) in the treatment of iron and zinc, it significantly outperformed most of the studied traits, while the bilateral interaction between the varieties and humic acid was significantly higher in most traits. Whereas the triple overlap between the varieties, the humic acid, and the iron and zinc elements, was significantly superior in most traits such as total trait yield, plant height and percentage of protein. | ||
