The Effects of Iron, Zinc and Bio-Fertilizers on Yield and Some Properties of Soybean (Glycine max (L) Merril) in Calcareous Soil Conditions

In this study, carried out in 2013-2014 for two years in Iran (Urmia) was aimed to determine the effects of foliar aplicaton of iron and zinc with applied of Plant Growth Promoting Rhizobacteria as biofertilizers (control, nitrogen fixing and phosphate solvent) on forage yield and some quality properties of soybean forage. The experiment was established in randomized complete blocks arrangement with four replications. In the study, were used soybean (Glycine max (L) Merril) Williams cultivar and nitrogen fixing (Azotobacter), phosphate solvent (Pseudomonas putida, strain P13, Pantoea agglomerans, strain P5) bacteria and Zinc and Iron micronutrients fertilizer. In this study, plant height (PH), number of branch per plant (BPP), leaf area index (LAI), dry matter yields (DMY) and crude protein percentage characteristics were investigated. According to the results, plant height, number of branch per plant, leaf area index (LAI), dry matter yield (DM) and crude protein percentage (CPP) varied between 111.5-142.5 cm; 2.5-3.7; 5.9-8.5; 12439-16965 and 13.2-16.4 respectively. The positive responses were observed for phosphate solvent (Pseudomonas putida, strain P13, Pantoea agglomerans, strain P5) bacteria, nitrogen fixing bacteria (Azotobakter) and foliar aplicaton of iron and zinc, since the soils of experiment plots were poor of this element on yield and quality of foarage soybean.
