Response of Yield and Yield Components of Three Red Bean (Phaseolus vulgaris L.) Genotypes to Co-Inoculation with Glomus intraradices and Rhizobium phaseoli

The use of biotechnology with the aim of using soil beneficial organisms to produce maximum production, improving soil quality and considering hygiene and environmental safety, has been considered. In order to investigate the effect of biological fertilizers on beans yield and yield components, a field study was conducted during spring and summer 2010 in agricultural experimental station of Arak Islamic Azad University. A factorial experiment was arranged in randomized complete block design with three replication. Three beans varieties Goli (indeterminate), Sayad (Semi determinate) and Derakhshan (determinate) were used. Mycorrhiza fungi including no inoculation and Glomus intraradices and three levels of Rhizobium phaseoli (no application, strain Rb116 and strain Rb133) were used. Interaction between Mycorrhiza, Rhizobium and cultivars on yield and yield components showed highest seed yield (2664 kg ha ) and biological yield (6333 kg ha ) 11 in treatment of inoculation Goli variety with both mycorrhiza (Glomus intarardices) and Rhizobium strain Rb133, respectively. The lowest yield (1172 kg ha ) was obtained in treatment not using Mycorrhiza fungi and 1 Rhizobium bacteria with variety Derakhshan.
