Field trial was conducted during season 2010 at Itay El-Baroud Center Bohera Governorate, to study the effect of bio-inoculation of common bean (phaseolus vulgaris L,) cv. Montano (a one of export variety) with Rhizobium phaseoli, Thiobacillus thioparus and Bacillus megatherium v. phosphaticum with or withoutorganic manure as comparison between (Farmyard manure and compost by rate 10m³/fedd. of each). Also soil was amended with agricultural sulfur and milled rock phosphate 50kg/fedd. as separately or combined treatments. Plant characteristics were measured as means of true nodule formation numbers, plant heights, no. of pods, fresh and dry weights of each character as well as NPK content of whole plant treatment. The obtained results revealed the positive effect of combined treatments then separately. Organic manure combined with three bacterial inoculants as well as soil amendments by sulfur and milled rock phosphate gave the best results compared with the other treatments. However, compost treatments as combined were better than farmyard manure. Also NPK of whole plant contents was higher amount due to combined treatments than separately. From these results could be of value as for productivity and reduction of pollution recommended that application of a bio-organo-fertilizer for common bean production.
