Abstract

Plant growth promoting (PGR) Rhizobacteria enhances, directly or indirectly, growth and YIELD of plant. In this research, the efficiency of four strains of FLUORESCENT PSEUDOMONADS on growth index of RICE is determined under saline condition. A pot experiment based on factorial completely randomized design was carried out with four replications. Five levels of saline irrigation water (700, 1400, 2800, 4200 and 5600 mS/cm from sea water source) and four inoculants (P. putida 11, P. putida 4, P.putida 108 and P.fluorescens 169) and a control (no inoculation) pot were used. RICE plant roots were inoculated with desired strains and transplanted in pots. During the growing period, the pots were irrigated with the abovementioned saline waters to the saturation point. Before harvest stage, GROWTH INDICES such as plant height, number of tillers and number of spikelet were measured and, after harvest, dry weight of shoots, 1000 grain weight, and grain YIELD were determined. Results indicated that, with increasing salinity level, the amount of grain YIELD, 1000 grain weight, number of tillers, plant height, and dry weight of shoots decreased significantly (P<0.01). Meanwhile, inoculation with the bacteria strains increased the mentioned indices significantly at all salinity levels. Among the strains, P. fluorescent 169 exerted the greatest effect on YIELD, number of tillers, plant height, and dry weight of RICE shoots in saline and non-saline conditions. Therefore, in saline condition, strains of Fluorescent pseudomonas can be used for promoting growth and YIELD of RICE.
