Conteúdo: 	Fababean (Vicia faba L.) is one of the oldest known important grain legume food crops grown within the temperate and sutropical regions of the world. This species is adapted for both forage and food grain production as a cool season annual crop on a wide range of soil and climatic conditions with effective tripartite symbiosis. Both Rhizobium and endophyte mycorrhiza are essential for high levels of production and symbiotic N2 fixation. The objective of these greenhouse and field studies was to determine effects of Glomus fasciculatum colonization with soil fertility treatments to a Psammentic paleustal f (eufaula series) on growth, nodulation, nitrogenase activity and nodule composition forV.faba, var. Major, fuh rumi(Nile) inoculated with R. leguminosarum Frank. Top growth and nodule mass were increased approximately 10 fold and nitrogenase activity about 7 fold with the higly significant effect of mycorrhiza and response to low soluble Ca3(PO4)2 fertilization in greenhouse studies. With both effective mycorrhiza and Rhizobium inoculation in the field experiments, seed yields were correlated with top growth(r=0.841). Phosphorus and Ca fertilization resulted in highly significant increases in seed yields. Nitrogenase activity was correlated with nodule wt.
