Abstract
A Randomized complete block design (RCBD) field experiment was conducted to determine the effect of varieties and foliar nutrition with manganese and zinc on some growth traits of soybean Glycine max (L.) Merrill which was sown in two sites; in field crops of the Faculty of Agriculture - Research Station Tikrit University in the city of Tikrit, and the in Samarra located 60 km south of Tikrit city, during 2013 summer agricultural season. The study consisted of three soybeans varieties (Industrial/2, Iman and Shaima), with three concentrations of manganese foliar fertilizer application (0, 75 and 100 mg MnSO4. H2O mg.L-1), and three concentrations of zinc (0, 50 and 75 mg ZnSO4.7H2O mg.L-1). Results showed that Iman variety was superior with interaction of the three factors on plant height (cm) and height of the first Pod (cm) for both sites, while with combination of two factors in samara location Iman variety showed higher recorded data for number of brunches plant-1 and leaf area in Tikrit location. For two factors combination manganese concentration level of 75 and 100ppm showed superiority in both studied locations when treated Zn75. Whereas zinc foliar application caused higher averages for leaf area (cm plant-1), yiled (kg ha-1) in Tikrit location and the first pod height for both sites.
