Abstract

Plant growth promoting rhizobacteria can enhance growth and yield of different crops through direct and indirect mechanisms. In this experiment, effect of PHOSPHATE SOLUBILIZING pseudomonads strains on yield, growth parameters and phosphorus uptake of three rice cultivars was studied. The experiment was carried out in a randomized complete design (RCD) in factorial experiment with four replications. Three cultivars of rice Tarom, Neda and Khazar, and six strains of FLUORESCENT PSEUDOMONADS GO11, GO12, GO15, GU10, MZ3 and MZ16 were used along with a control treatment. The collected data included weight of fresh shoot, weight of dry shoot and phosphorus uptake by plant at flowering stage, and yield of grain, 1000 seed weight, number of panicles, number of spikelets, number of grains per panicle, and phosphorus uptake in grain at maturity. Results of the experiment showed that all the parameters according to Duncan test (P≤0.05) were significantly affected in different cultivars. Maximum grain yield was obtained from Neda cultivar. Inoculation with strains increased all plant biometrical parameters, growth indices and yield of rice. Maximum grain yield (30.61g per pot) was obtained with P. fluorescens GO15 strain and showed a significant increase in comparison with the control, (24.5%.). Maximum grain yield and growth indices were obtained from inoculation of seeds of Neda cultivar with P. fluorescens GO15.Maximum rates of P uptake in plant and grain of rice were obtained from interaction of P. fluorescens GO12 with Neda and Khazar cultivars, respectively. Based on the obtained results, FLUORESCENT PSEUDOMONADS could affect yield of rice and P uptake in plant and grain.
