Growth and Yield of Three Soybean Cultivars by the Nutritional Effect of Zinc and Arginine

Abstract To examine the impact of foliar feeding with zinc and arginine acid on some physiological productive traits soybean cultivars, an experiment was carried out in fields a crop Al-Khalidiya Island area Al-Anbar Governorate, at 43° longitude 33° latitude, sandy mixture soil. The conducted using randomized complete block design (R.C.B.D), split-split plot, three replicates, concentrations (50.0 100 mg ZnL −1 ) main plates, (40.0 80 Arl secondary varieties (D, Shaima, Lee) sub-secondary plates. Results from are summarized as follows: highest mean for all studied found Zinc concentration Zn l , which also outperformed 50 control treatment. Arginine 40 L achieved rate leaf nitrogen percentage leaves, while gave average root length (28.77 cm), number pods per plant, fertility pod (95.39%) plant seed yield (58.21 g ). Leaf count were best Shaima variety, whereas length, fertility, output Lee variety. content different cultivars did not differ appreciably.
