Abstract

In order to evaluate the effects of different strains of Pseuodomonas on nutrients uptake efficacy and RICE YIELD, an experiment was carried out in RICE Researches Institute of Guilan Province (Rasht) in 2009. The experiment design consisted of four randomized complete blocks in a factorial arrangement. In this research, two factors were evaluated: first, two cultivars (Khazar and Hashemi) and second, eight levels of seed inoculation with PGPB strains (168, 93, 177, 136, 103, 169, 4 and the control (without inoculation)). Investigated characteristics consisted of: nitrogen consumption efficacy, phosphorus consumption efficacy, potassium consumption efficacy, phosphorus harvest index, apparent recovery efficacy of nitrogen and phosphorus, physiological efficacy of nitrogen and phosphorus, agronomic efficacy of nitrogen and phosphorus, YIELD and YIELD components (number of seed per panicle, number of panicle per panicle and 1000-seed weight). In this experiment, effects of bacteria were significant in the most of studied characteristics. The results of experiment showed that inoculation with bacterial strains had a significant effect on RICE cultivars, so Khazar had better response on the most of studied characteristics in comparison with Hashemi. Between bacterial different strains, seed inoculation with 168 strain in comparison with other strains increased evaluated characteristics significantly. The findings of this research showed that PGPB could positively interact in promoting plant growth. As nutrients uptake of RICE plants in soil especially P increased the solubility of ions through increased enzymes activities and production of growth hormones that consequently, led to improved YIELD.
