- Abstract
A field experiment was carried out in the autumn season of 2020 in Al-Baghdadi region, Ramadi district, Anbar Governorate, to study the response of some physiological traits of mung bean to foliar nutrition with arginine and iron. Split plots arrangement according to randomized complete block design was used at three replications. Iron concentrations (0, 60, 120 and 180 mg L-1) occupied the main plots, while arginine concentrations (0, 50 and 100 mg L-1) occupied the sub-plots. The results showed that the spraying of arginine at a 50 mg L-1 gave the highest means of leaves content of nitrogen and soluble sugars, whereas the 100 mgArginine L-1 gave the highest means of plant dry weight, CGR, number of branches per root, leaves content of hydrogen peroxide and SOD enzyme activity. Also, the spraying of iron at a 60 mg L-1 was significantly superior and achieved the highest mean of SOD enzyme activity (126.87 unit ml-1 protein), while the 120 mg Iron L-1 had the highest means of leaves content of nitrogen (2.39%) and number of branches (16.4 branch root-1), whereas the 180 mg Iron L-1 gave the highest means of leaves content of soluble sugars (13.80%), plant dry weight (16.65 g plant-1), CGR (11.154 g m-2 day-1) and leaves content of hydrogen peroxide (4.04%). The interaction between arginine and iron had a significant effect on most studied traits, arginine at 100 mg L-1 with iron at 180 mg L-1 gave a highest value of plant dry weight, CGR and leaves content of hydrogen peroxide
