| Abstract | ||
| Two field experiments were conducted at EL-Mahmodia region, (Behera Governorate) Egypt, to assess the influence of applying four different fertilization levels of mineral phosphourous (0, 30, 60 and 90 Kg P fed- 1. ) in addition to seed inoculation with phosphorous solubilizing bacteria (Bacillus megaterium; cited as a commercial product phosphorein from Agriculture Research Center), and arbuscular mycorrhizal fungi (Glomus macrocarpium) on the growth and flowering traits, green pod yield and its components and leaves contents of N , P and K of bronco cultivar of common bean (Phaseolus vulgaris L.) cv. "Bronco . The results showed that mycorrhiza and phosphorein had similar effects on vegetative growth characters and flowering traits; meanwhile, mycorrhiza gave a higher yield fed-1 than the inoculation with phosphorein in both seasons.On the other hand fertilizing common bean plants with inorganic phosphorus at the rates of 30, 60 and 90 kg P2O5 fed-1, significantly, increased most of vegetative growth characters, number of flowers plant-1 , fruit set percentage , green pods yield and N and P contents of leaves; compared to the control treatment in both seasons. The highest two phosphorus levels (60 and 90 kg P2O5 fed-1) were remarkable and associated with the highest mean values in this concern, whereas, the differences between them were insignificant. Most of the interaction effects of biofertilizer types and mineral phosphorus levels on the various studied characters were found significant in both seasons. The combined treatments of mycorrhiza and 60 kg P2O5 fed-1, was considered the best treatment combinations, and gave the highest mean value of green pods yield in both seasons. | ||
