| Abstract | ||
| An experiment was conducted at the Research field Station of the Field Crops Department - College of Agriculture - University of Tikrit for the winter season of 2023-2024, to study the influence of spraying salicylic acid and zinc on beans (Vicia faba L.) growth. The factors of the experiment included spraying the bean plants with salicylic acid with a concentration level of 100, and 150 mg L-1 and control treatment. The second treatment factor was spraying with zinc at a concentration level of 100 mg L-1 and the control treatment. The experiment design was applied according to the complete randomized block design system with three replicates, and the averages were compared according to Duncan's multiple-nominal test at a probability level of 0.05. outcomes appear that the spray treatments with salicylic acid 100 and 150 mg L-1 did not significantly different in all studied traits except for the trait of plant height and leaf area, in which the concentration level exceeded 150 mg L-1, and reached 3.93 cm, 2252.17 cm2 per plant, respectively. As for the spray treatment with zinc at a concentration level of 100 mg L-1, it was significantly superior in the traits of plant height, number of branches, number of leaves, leaf area, and leaf content of chlorophyll, and reached 49.11 cm, 4.93 branch plant-1, 37.96 leaf plant-1, 2352.44 cm2 plant-1, 48.16 spad, respectively. As for the two-way interaction, the spray treatment with salicylic acid at 150 mg L-1 and the spray treatment with zinc at 100 mg L-1 were superior. In the traits of plant height, number of branches, number of leaves and leaf area, and leaf content of chlorophyll, they reached 52.36 cm, 5.90 branch plant-1, 41.46 leaves plant-1, 2969.00 cm2 plant-1, 51.00 spad respectively, while the lowest averages were recorded for the control treatment. the interaction between the spray treatments with salicylic acid and zinc 150 mg L-1 recorded the highest average for the traits, amounting to 52.63 cm for the Plant height, 2969.00 cm2 for leaf area, and 51.00. SPAD average of chlorophyll, 41.46 leaves for the number of leaves trait, and 5.90, branch for number of branches per plant. | ||
