| Abstract |
Two field experiments were conducted at Sids Agricultural Research Farm , A.R.C. Beni Swif Governorate to study the effect of Rhizobium or in combined bio-fertilizer (Biogen) inoculation or without inoculation under N , P and Mo application on nodulation , i.e. number of nodules/plant and dry weight on nodules /plant ; yield components (number of pods/plant , number of seeds/pod and 100-seed weight) and grain and straw yields of soybean crop . Factorial experiment (four factors) were used with randomize complete block design with four replications . The factors were : bacterial inoculation (without inoculation , Rhizobium inoculation only and Rhizobium + bio-fertilizer (Biogen) inoculation) , nitrogen application (30 and 60 kg N/fed) , phosphorus application (0.0 and 13.1 kg P/fed) and molybdenum application (0 and 5 kg molybdate sodium /fed) . The results show that , with respect to the main effect , number of nodules /plant and dry weight of nodules/plant , number of pods/plant , 100-seed weight and grain and straw yields were positively responded to microbial inoculation , nitrogen application up to 60 kg/fed and phosphorus and molybdenum application , except the dry weight of nodules/plant , which negatively responded to increasing nitrogen level and did not affected by molybdenum application . The dual inoculation with Rhizobium combined with bio-fertilizer surpassed the single inoculation Rhizobium only . However number of seeds/pod not affected by the studied factors . But the interaction between the studied factors in consideration , the statistical analysis show that the high level of nitrogen had a antagonistic action of the promotive effect of bacterial inoculation or molybdenum on nodulation and yield and its yield components of soybean . On the other hand added phosphorus had a synergistic effect on enhancing the effect of bacterial inoculation or molybdenum on the studied parameters . In general , the highest values of number of nodules/ plant , number of pods/plant , 100-seed weight and grain and straw yields were produced under dual inoculation + 30 kg N/fed + 13.1 kg P/fed + 5 kg molybdate sodium/fed
