Abstract

To evaluate the effect of microbial inocula application on the yield and nutrients content of Dracocephalum moldavica L. seeds, a field experiment based on randomized complete block design with four replications was conducted at the Agricultural and Natural Resources Research Center of West Azerbaijan (Urmia, Iran) in 2010. Treatments were microbial inocula [seed inoculation with nitrogen fixing bacteria (Nb), phosphate solubilizing bacteria (Pb), sulfur oxidizing bacteria (Sb), Nb+Pb, Nb+Sb, Pb+Sb, Nb+Pb+Sb], chemical fertilizer (nitrogen+phosphorus+potassium of chemical origin (NPK)) and control (no fertilizer). The highest yield of seeds (3366 kg ha-1) was obtained in the NPK treatment. Maximum seed nitrogen (3.74 %) and manganese (0.0062 mg kg-1) contents occurred in Nb treatment. The highest percentage of sulfur (0.56 %) and content of zinc (0.184 mg kg-1) were obtained in Sb treatment, while the maximum iron content (0.62 mg kg-1) was observed in the Nb+Pb+Sb. In conclusion, seed inoculation with sulfur oxidizing bacteria (Thiobacillus strains) improves nutrients availability in calcareous soils
