Abstract
Phosphorus ( P) is considered limiting factor for growth and productivity of legume crops . Two field experiments were conducted at the experimental Farm of Tag El- Ezz Station, Dakahlia Governorate ,Egypt during 2010/2011 and 2011/2012 seasons, to study the productivity of three faba bean cultivars namely ( Sakha 1, Nubria 1 and Giza 843) under three phosphorus levels, i.e. (15.5, 23.25 and 31Kg P2O5/fad.)with three types from solubilizing phosphate fungi ,i.e. ( Aspergillus Oryza, Aspergillus Niger and PenicilliumPurpurogenum ). The results indicated that there were significant differences among the tested varieties in most characters studied in both seasons and combined analysis. Sakha 1 gave the highest values of nodules and root weight compared with other cultivars. Adding super phosphate at the rate of 31 kg P2O5 gave the highest values of nodules and roots weight compared with the other phosphorus levels and using fungi A .Niger recorded increase in nodules and root weight after 45 and 60 days from sowing in both seasons. On the other hand, growth and yield attributes as well as seed yield /fad. were significantly increased with the increase of phosphours level from 15.5 to 31 kg P2O5/fad. Inoculation faba bean seeds with A. Niger and A. Oryza gave the highest values for seed yield and yield attributes for all faba bean varieties in both seasons and combined analysis . on the other hand Sakha 1 produced the highest seed yield .( 8.18, 8.28 and 8.23 ardab/fad.) compared with 7.83 ,8.03 and 7.93 ardab/fad. for Nubria 1 and (8.02,8.25 and 8.15 ardab/fad.) for Giza 843 in both seasons and combined analysis respectively. The results obtained revealed that , there are significant differences in P% values , between studied cultivars , Sakha 1 gave the highest values compared with the other cultivars . On the other hand, adding 31 Kg P2O5 and the inoculation with A. Niger gave the highly significantly P% in roots and shoots in both seasons . Also the interactions effect between all studied factors on P% in root and shoot are highly significantly in both seasons
