Influence of rhizobium inoculation combined with pseudomonas and herbaspirillum on growth, nodulation and yield of faba bean under newly reclaimed soils [electronic resource].

Four field experiments were carried out at newly reclaimed soil In Minia and New Valley governorates during winter-growing seasons 012003/04 and 2004/05 to stUdy the effect 01 inoculation with Rhizobium leguminosarum combined with Pseudomonas /luorescens and Herbaspirillum on nodulation, growth, nitrogen content and yield 01 laba bean. The results showed that the inoculation 01 laba bean plants with Rhizobium only or in combination with Pseudomonas or Herbaspirillum caused significant increases in nodules number and dry weight compared to the uninoculated plants which received 15 kg N/led in Minia and New Valley at the first 2nd second seasons. Triple inoculation with Rhizobium, Pseudomonas and Hecbaspirillum combined with starter dose 01 nitrogen lertilizer (15 kg N/led) recorded significant increases in shoot dry weight and its nitrogen content compared to the uninoculated plants which received the same starter dose or received lull dose 01 nitrogen (30 kg N/led) or rhizobial inoculation only plus 15 kg N/led. The maximum seed and straw yields were obtained in plants inoculated with triple inoculation (Rhizobium, Pseudomonas and Herbaspirillum) plus 15 kg N/led, lollowed by plants Inoculated with rhizobia combined with Pseudomonas or Herbaspirillum plus 15 kg N/led in Minia and New Valley at the first and second seasons. Regarding to the two locations, data revealed that there are significant increases in nodulation, growth, nitrogen content, seed and straw yields. New valley recorded the higher mean values 01 these parameters than Minia. On the other hand, there are no-significant differences between the two seasons.
