- Abstract
A field experiment was carried out in the autumn season of 2020 in Al-Baghdadi region, Ramadi district, Anbar Governorate, to study the effect of foliar nutrition with iron and arginine on some physiological traits of mung bean (VC6089A10cv.). Split plot arrangement according to randomized complete block design was used with 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 arginine at 50 mg L-1 gave the highest means of plant height, chlorophyll index, iron concentration in leaves and nitrate reductase enzyme activity, while the 100 mg L-1 gave the highest means of leaf area, root length and NAR. Iron at concentration of 120 mg L-1 was significantly superior and achieved the highest means of plant height, root length, chlorophyll index, iron concentration in leaves and NAR, while the 180 mg L-1 had the highest means of leaf area and nitrate reductase enzyme activity. The interaction between arginine and iron had a significant effect on chlorophyll index, iron concentration in leaves, NAR and nitrate reductase enzyme activity. Iron at 180 mg L-1 with arginine at 100 mg L-1 gave a highest value of NAR (1.5663 g m-2 day-1), whereas iron at 180 mg L-1 with a arginine at 50 mg L-1 gave a highest nitrate reductase enzyme activity (158.0 ìmol NO2 g-1 fresh weight h-1).
