  A factorial design experiment was conducted on field to investigate the effects of inoculation with AM fungi (Glomus mosseae), phosphate solubilizing bacteria strain (Bacillus polymyxa) and soil yeast strain (Saccharomyces cerevisiae) on growth, phosphorus content and yield of onion plants in calcareous soil under different levels of phosphorus fertilization (P1: 50, P2: 100 and P3: 200 kg ha-1). Results showed that inoculation with G. mosseae or B. polymyxa significantly (p = 0.05) increased plant height, shoot fresh and dry weights, root fresh and dry weights, average bulb diameter and total yield. The highest total yield and average bulb diameter were obtained from the inoculation treatment of AM fungus G. mosseae, recording 14.4 and 40.8% increases, respectively over the uninoculated control. Also, inoculation with AM fungus (G. mosseae) had a significant increase in all mineral content in onion plant compared with uninoculated control or other biofertilizers inoculation treatments (B. polymyxa or soil yeast strain S. cerevisiae). Only, inoculation with phosphate solubilizing bacteria B. polymyxa had significant increase in P content and non significant increases in N, K, Fe, Zn and Mn. Inoculation with soil yeast S. cerevisiae had a non-significant increase in all minerals content of onion plant.

  Background: Mixed inoculants are used for many crops grown under field condition and many studies have shown that mixed inoculants containing mixture of bacterial species promote greater beneficial effects than single strain inocula. Materials and Methods: A pot experiment was conducted to study the effect of inoculation with A. chroococcum or plus yeast strains (Saccharomyces cervisiae, Candida sake, Saccharomyces exiguous, Pichia membranifaciens and Cryptococcus laurentii) on grain germination, growth of wheat (Triticum aestivum L.) cv., Giza-64 and to choose the best yeast strain for inoculation under field condition. Results: The results showed that the mixed inoculation of any of the yeast strains with A. chroococcum except yeast strain Cryptococcus laurentii resulted in significant (p≤0.05) increases in shoot fresh and dry weights, root fresh and dry weights. The most stimulative treatment on all plant growth parameters was that inoculated with A. chroococcum+Candida sake, scoring the following increases in germination, shoot fresh and dry weight and root fresh and dry weights making 134.09, 210.9, 30.23, 20.71 and 71.60%, respectively, compared with the single inoculation treatment with A. chroococcum alone. The response of wheat to co-inoculation with A. chroococcum and the selected yeast strain (Candida sake) was tested in season 2015/2016 under field condition in presence of different N levels (40, 60 and 80 kg N feddan–1). The dual inoculation treatments of A. chroococcum+yeast strain C. sake under any of the N levels produced significant (p≤0.05) increases in fresh and dry weights of shoots and roots, N-uptake and grain yield of wheat compared to the single inoculation treatment with A. chroococcum alone. Conclusion: Dual inoculation with A. chroococcum+yeast strain C. sake along with 60 kg feddan–1 is recommended for wheat fertilization in Egypt since it gave highest grain yield and was equal to that obtained with dual inoculation+80 kg feddan–1, thus saving 20 kg N-fertilizer feddan–1. The magnified promotion induced by the mixture of the yeast strain C. sake and A. chroococcum may indicate a synergetic interaction between them.
