Accumulation of Nutrient Elements on Root, Straw and Soil in Dryland Wheat as Affected by Phosphate Solubilizing Bacteria and Mycorrhizal Fungi

In order to study the effect of Pseudomonas putida and Glomus mosseae on accumulation of nutrient elements residual on root, straw and soil in wheat under dryland conditions, an experiment was carried out in a factorial arrangement using randomized complete block design with three replications at Agricultural Research Station of Ilam University and Sarableh Agricultural and Research, Recources Center during 2013-2014 cropping season. Experiment factors consisted of two dry land wheat cultivars (Keras Sablan and Saji) and fertilizer sources treatment including of 1- without application of phosphorus chemical fertilizer, 2- 50 kg ha-1 P, 3- Pseudomonas putida (PSB), 4- Glomus mosseae (GM), 5-PSB+GM, 6-PSB+GM+25 kg ha-1 P, 7- PSB+ 25 kg ha-1 P and 8- GM+25 kg ha-1 P. Results indicated that interaction effect between cultivar× fertilizer sources had significant effect on accumulation of nutrients elements residual in root, straw and soil in dryland wheat at 1% probablity level. Application of PSB and GM caused increased in N, K, Fe and Cu in soil and the lowest N, P, K, Zn, Fe, Cu and Mg were obtaind in root and straw. The highest N, K, Fe and Cu in soil belonged to Saji cultivar× GM+25 kg ha-1 P. Root and straw had the highest N, P, K, Zn, Fe, Cu and Mg in root and straw in Keras Sabalan×check treatment (without feriilizer sources).
