The effect of interactions between three phosphate-dissolving fungi (PDF) (Aspergillus niger, A. fumigatus and Penicillium pinophilum) and Rhizobium leguminosarum biovar viciae (RH) was studied on some soil chemical properties, phosphorus and nitrogen uptake and yield of faba beans (Vicia faba L.). Analysis of the soil after crop harvest indicated that the inoculation with PDF and RH significantly increased the levels of soil available P, mineral N (NH4<SUp>+</SUp>-N+ NO<SUp>-</SUp> 3-N) as compared to the untreated soil. The highest level of available P was recorded under the treatment RH1 + 31 Kg P2O5 fed<SUp>-1</SUp> + P. pinophilum. The highest value of soil total N was observed with the treatment RH1 + 15.5 kg P2O5 fed<SUp>-1</SUp> + A. niger. Values of soil pH and total N were not significantly affected by the soil inoculation with PDF. The inoculation with RH and PDF significantly increased seeds and straw yields of faba beans as compared to the untreated plants. The maximum seeds and straw yields of 1272 and 1871 Kg fed<SUp>-1</SUp> respectively, were achieved in the treatment RH1 + 31 Kg P2O5 fed<SUp>-1</SUp> + P. pinophilum. The highest P uptake by plants was also achieved under the same treatment. The highest N uptake was recorded with the combination RH1 + 31 Kg P2O5 fed<SUp>-1</SUp> + A. fumigatus. It was clearly evident that the ordinary used quantity of SP fertilizer could be reduced by 50%, in the presence of PDF, without any significant effect on the yield of Vicia faba (L.). |
