Title

EVALUATION OF RED BEAN (PHASEOLUS VULGARIS) SEEDS CO-INOCULATION WITH RHIZOBIUM PHASEOLI AND PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) ON GRAIN YIELD AND ITS COMPONENTS

Pages

Abstract

 To evaluate seeds inoculation effects on Iranian bean (Phaseolus vulgaris L.) cultivars with different strains of Rhizobium leguminosarum biovar phaseoli with Plant growth promoting bacteria (PGPR) on yield, N2 fixation rate and determining the best bacteria× cultivar combination, a spilt plot experiment in randomized complete block design was conducted in the training farms in Islamic Azad University Shahrekord, Iran in 2006 and 2007. The factor A was six bacterial strains Rb-133, Rb-133 + Azospirillum, Rb-133 + Pseudomonas, Rb-136, Rb-136 + Azospirillum, Rb-136 + Pseudomonas and non-inoculated controls including with and without application of nitrogen fertilizer treatment (100 kg­ N ha-1 ). Three bean cultivars Sayad, Akhtar and Goli were assigned as factor B to subplots. The results revealed that there were significant differences among factor A in GRAIN YIELD, number of pods per plants, number of seeds per pods, number and weight of nods at early flowering (45-50 days after emergence), shoot nitrogen content and N2 fixation rate. Treatment of inoculated seeds with strain bacteria × Pseudomonas and non-inoculated control (without N–fertilizer application) demonstrated the highest and lowest GRAIN YIELD, respectively. The interaction between strains × cultivars effects in seed yield were not of significant difference, but the results of mean comparison by DMRT (at 5% level) showed the highest and lowest seed yield associated to Akhtar + Rb-133 + Pseudomonas and Goli + control respectively. The results showed that all treatments of bacteria were capable of nodulation; however, strains Rb-133 gave highest nodule dry weight, N total (shoot) and percent of fixed N2. An efficient symbiosis was achieved with strain Rb-133, since total N content of plants inoculated with these strains and N content in soil after harvesting in main plots were similar to that of plants supplied with N –fertilizer treatment.
