| Abstract | ||||
| Two field experiments were conducted 2015 and 2016 to study the influence of rhizobium and/or mycorrhiza inoculation under 50% of recommended mineral nitrogen and phosphorus doses compared with 100% recommended doses of nitrogen and phosphorus (control) on growth, pods yield and its components and leaf chemical constituents of snap bean cvs. Paulista and red kidney bean plants. The obtained results, obviously, study revealed that the red kidney bean showed better performance significantly than Paulita for all the studied characters, in both seasons. Fertilization treatment of 100%NP and/or 50%NP + dual inoculation with rhizobium and mycorrhiza gave the most favorable effect comparing with other fertilization treatments for all studied characters, in both seasons; without significant difference between them; except for 100%NP which gave significant higher shoot fresh weight compared with 50%NP+RM, in both seasons. The interaction effect between bean cultivars and fertilization treatments showed significant superiority of 100%NP or 50%NP+ dual inoculation of rhizobium and mycorrhiza with red kidney bean for most cases without significant difference between them, in both seasons. Results of this investigation referred to the ability of reducing nitrogenous and phosphorus mineral fertilization with 50% by using the dual inoculation of mycorrhiza and Rhizobium for achieving the same growth and yield with lowering the consequential environmental hazardous from intensive mineral fertilization use. | ||||
