“…tuber −1 and 6.59%, respectively. Foliar spraying plays an important role in improving plant growth and increasing its productivity by supplying it with its needs of various nutrients that contribute to many diverse physiological activities in plant tissues [9,10], Potassium is one of the main nutrients that the plant needs to complete its life cycle and is very important for all root crops because of its role in transporting nutrients from the leaves to the storage roots, such as ordinary potato) [11], [12] and sweet potato [13], in addition to its well-known roles, as it directly affects the process of photosynthesis in plants [14] and controls metabolism [15], as well as its activation of more than 60 enzymes and participates directly in protein synthesis [16], and also improves nutrient absorption [17]. [18] mentioned an experiment conducted in Nepal regarding the potato plant's response (production and storage) to certain levels of potassium and spraying with some micro-and macronutrients by spraying potassium sulphate K2SO4 at five levels (0, 150, 300, 450, 600) kg.…”

A field experiment was conducted in one of the fields affiliated with the College of Agricultural Engineering Sciences/University of Baghdad. The experiment included two factors: the first factor, benzyl adenine, at three concentrations: 0, 1, and 2 g.L-1, and the second factor was spraying with potassium chloride at two concentrations: 0 and 10 g.L-1. The experiment was conducted using a randomized complete block design (R.C.B.D) with three replications. The results were analyzed statistically according to the Genstat program, and the arithmetic means of all studied traits were compared according to the least significant difference (L.S.D) test at the 5% probability level. The results showed that the spraying treatment with benzyl adenine at a concentration of 2 g.L-1 was excelled in increasing the plant height and the length of the leaf stalk, which reached 224.2 cm and 25.44 cm, respectively, and in increasing the dry matter in the plant, the chlorophyll content, the number of tubers, and the total plant yield, which reached 1454 g and 54.80 mg. 100 g fresh weight-1 and 3.00 root tubers. Plant-1 and 612 g. Plant-1, respectively. The spraying treatment of 10 g.L-1 with potassium chloride also affected the increase in plant dry matter, chlorophyll content, and plant yield, reaching 1307 g and 50.13 mg. 100 g fresh weight-1 and 650 g. plant-1, respectively. As for qualitative yield indicators, spraying treatment with benzyl adenine at a concentration of 1 g.L-1 increased the percentage of total soluble solids and the content of beta-carotene pigment and carbohydrates in the tuber roots, reaching 10.55%, 0.377 mg.100 ml-1, and 18.16%. The concentration of 10 g.L-1 of potassium chloride increased the content of lycopene and carbohydrates in the tuber roots, reaching 0.132 mg.100 ml-1 and 16.64%, respectively, as evidenced by the results of bilateral interaction of the studied factors, indicating a significant increase for most of the traits mentioned above.

Broad bean mottle virus (BBMV) infects a wide range of hosts, resulting in significant production reductions. The lack of adequate and effective control methods involves implementing novel BBMV control strategies. Herein, we demonstrate the effect of different potassium concentrations (20, 40, and 60 mM) against BBMV in broad bean plants. Potassium could control BBMV infection in broad bean by inhibiting the virus. In addition, infection with BBMV caused a significant decrease in morphological criteria, SPDA, photosynthetic characteristics, phytohormones, and mineral content in broad bean leaves compared to control plants. The levels of reactive oxygen species (ROS) (hydrogen peroxide, hydroxyl radical, and oxygen anion) and ROS scavenging enzymes (catalase, superoxide dismutase, peroxidase, phenylaniline ammonia-lyase, chitinase, and 1,3 - glucanase) increased significantly in plants inoculated with BBMV alone or in the presence of K+. In addition, proline and phenolic compounds increased significantly after being infected with BBMV. In conclusion, treatment with a high potassium concentration (60 mM) alleviates the adverse effect of BBMV on broad bean plants by boosting secondary metabolites, phytohormones, and enzymatic antioxidants.
