Effect of phosphate and sulfur solubilizating microorganisms and zinc foliar application on nutrient uptake of soybean

Abstract In order to study the effects of phosphate and sulfur solubilizating microorganisms and zinc foliar application on yield, oil and protein percentage and nutrients uptake in soybean (Glycine max L.) cultivar TMS, a field experiment was conducted in summer 2010 in Aleshtar, Lorestan, Iran on a calcareous clay loam soil. The treatments were arranged in a factorial design based on randomized complete blocks design (RCBD) with 3 replications. The treatments included : 1- inoculation with Pseudomonas fluarescens, 2- inoculation with Thiobacillus thiooxidanc, 3 - inoculation with Pseudomonas fluarescens + inoculation with Thiobacillus thiooxidanc, 4 - zinc foliar application, 5 - inoculation with Pseudomonas fluarescens + zinc foliar application, 6 – inoculation with Thiobacillus thiooxidanc + zinc foliar application , 7 – inoculation with Pseudomonas fluarescens + inoculation with Thiobacillus thiooxidanc + zinc foliar application and 8 – no treatment . The results of comparison showed the highest grain yield with 4133.2 kg per hectare obtained in T3(Pseudomonas fluarescens + Thiobacillus thiooxidanc) and the highest oil percentage with 21.26% obtained in T7(Pseudomonas fluarescens + Thiobacillus thiooxidanc + zinc foliar application).
