Two field experiments were carried out during 2005/2006 and 2006/2007 seasons at Agricultural Experimental Station of Desert Research Center (DRC( in Maryout region (Alexandria Governorate(, to study effect of interactions between Biofertilizers (Biovit, Netrobin, Phosphorin( and biofoliar application (Biomagic (B(( on biochemical components in faba bean (Vicia faba v.Nubaria- 1( under rainfed at Maryout conditions. The experiment included ten treatments, five biofertilizers (Control, Biovit, Nitrobin, Phosphorin and 1/2 Nitrobin and 1/2 Phosphorin( and biofoliar applications (Water as control and biomagic plus the previous biofertilizers treatments(. Nitrogen and phosphorus were added at a rate of 30 Kg calcium superphosphate (15% P205( and 60 Kg ammonium nitrate (33.5%N( per feddan during seed bed preparation in sand clay loam in texture and calcareous soil in nature. The obtained results showed that the treatment of mixture (Biovitand Biomagic( has the highest growth parameters, yield and yield components, than the control. Total carbohydrate and protein content in faba bean were significantly decreased with increase drought stress. The protein and carbohydrate contents were higher with mixture (Biovit and Biomagic( than the other treatments. Total soluble sugars, reducing sugars, proline, soluble protein and total amino acids content were significantly increased with increasing drought stress. Contents of K, Na, Ca and Mg were higher under drought stress with biofertilizer and biofoliar application (BiovitandBiomagic( than other treatments.
