Abstract

Plant growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. In this research the efficacy of four Pseudomonas fluorescents on yield and growth indices of WHEAT at various levels of phosphorus fertilization were in Two factorial experiments (a pot and a field experiment). The experiments were carried out in a completely randomized design in greenhouse and randomized complete block design in field trials. The first factorwas : three phosphorus levels based on soil testing (0, 50% and 100% recommended P fertilizer according to soil test)and the second factor was five levels of inoculation as (non –inoculation control ; inoculation with P. fluorescens strain 153; P.fluorescens strain 169; P. putida strain108 and P. putida strain 4).WHEAT seeds were planted after inoculation with test strains. All agronomic practices and inputs application during planting and nursing were conducted according to regional traditions. Before harvesting growth indices including: plant height, spike length and number of tillers, were determined. After harvest, biologic , grain and straw yield and 1000 grain weight were measured.Grain and straw samples were sent to soil and water lab and concentration of N, P and K were determined. Results showed that with increase in P level, grain yield, 1000 grain weight, plant height and biologic yield increased significantly at both greenhouse and field experiments .the effect of inoculation on yield and yield components of WHEAT was significant at all levels of P fertilization.The greatest amount of grain yield, 1000 grain weight and plant height obtained from Pseudomonas putida 108 together with application of 100% p recommended treatment and the least yield was obtained from control treatment(without p application and without inoculation). According to these results strains with ACC –Deaminase enzyme had greatest effects on yield and yield indices and so the ability of producing ACC-Deamiase is a good criteria and utilization of PLANT GROWTH PROMOTING RHIZOBACTERIA could be a suitable way in icreasing yield of WHEAT at various levels of phosphorus.
