| Abstract | ||||
| The present work was carried out on faba bean and wheat g:ops growing in sandy loam highly calcareous soil and sandy soil at West Nubaria region during the Winter seasons of 200012001 and 200112002, to study the effect of interactions between mycorrhizal rung; (AM), phosphate dissolving bacteria (PO B) and Rhizobium ieguminosarum biovar viceae (R) or Azotobac/ar chroococum (A) on growth, yield and nutrient uptake by faba bean and wheat plants. The experiments were lied out in a split-plot design with four replications. The main plots were for minera fertilizers (two levels) and sub-plots were for inoculation treatments (eight inoculation treatments). The results dearly showed that Inoculation with Rhizobium feguminosarum or Azotobacter chroococum singly or in combination with AM or poe and (AM + POS) markedly enhanced the yield and all the measured yield components of faba bean and wheat plants, as well as nutrients uptake by plants under calcareous and sandy soil conditions compared to uninoculaled or inoculated plants by AM and poe alone or the dual inoculation with (AM + POe). Nodulation of faba bean plants was positively affected by inoculation with Rhizobium andlor any other inocula mixed with Rhizobium. Faba bean and wheal dry weight was increased by abOut 25% due to inoculation with mixtures of AM + R + poe or AM + A + POB as compared 10 uninoculated plants or any other inoculation treatment. Nitrogen uptake by inoculated faba bean and wheat plants 'th Rhizobium and Azotobacter andlor their mixture with AM and poe was increas,d by 3.97 and 6.38%, with relative increase in seed yield by 11.28 and 3.72% as compared to uninoculated or inoculated plants with AM or poe and (AM + POe) for calcareous soil, respectively. While, It was increased by 8.95 and 44.1% with relative increase in seed yield by 16.42 and 6.85% for sandy soil. Inoculation with mycorrhiza or phosphate dissolving bacteria singly and with any of their combinations increased R-supply which led to Improve P-uptake by faba bean and wheat plants as compared to uninoculated or inoculated plants with Rhizobium and Azotobacter, it was Increased by 1.91 and 3.57% for calcareous soil and by 2.28 and 1.94% for sandy soli, respectively. In general, a highly response of faba bean or wheat plants to the inoculation mixed was observed to be higher than that for single Inoculation for the ~o tested soil types. This indicated that there was a positive interaction between he two andlor three inocula for the welfare of faba bean and wheat plants. | ||||
