Abstract

Two field experiments were carried out at Experimental Farm of Tag El-Ezz Agricultural Research Station (30^o 59^\ N latitude, 31^o 58^\ E longitude´), Agriculture Research Center, Dakahlia Governorate, Egypt. Split plot design with three replicates was used during the two successive winter seasons of 2018/19 and 2019/20 to study the effect of four phosphorus fertilizer sources (without addition, super phosphate (SP), phosphoric acid (PA) and di ammonium phosphate (DAP)) as the main plots and four organic acids treatments (control, citric acid (CA), salicylic acid (SA) and ascorbic acid (ASA)) as foliar application in the sub plots on growth, yield and its components of faba bean plants (Vicia faba L.) cv. Giza 716 which grown under salt affected soil. Available elements N, P and K in the experimental soil were determined after harvesting. The obtained results could be summarized as follow: DAP gave the highest values of vegetative growth, yield and its components compared to other phosphorus sources. ASA as a foliar application has a superior effect on all studied parameters compared to the other foliar treatments. The interaction between DAP and ASA achieves the highest values of vegetative growth criteria, yield and its components of the faba bean plant. The highest residual N, P and K (mg kg^-1) in the soil were recorded with the interaction of SP and CA application comparing with the other phosphorus fertilizers and organic acids treatments. The highest P use efficiency values were obtained by the combination of PA and ASA foliar application.
