Effect of salinity with use Different concentration 0f NaCI on some of growth properties and yield of Broad bean (Vicia faba L .) plant

Abstract

This study was conducted in AL – Qaraf region , Thi – Qar governorate during fall season of 2010 , The objective was concentrations of NaCl on some growth properties and yield of Broad bean .Seed of broad bean veraity (Rrina mora) ware planted during autumn seasons of 2010 .RCPD with three replication was the design and five concentrations of NaCl (0, 50 , 100 ,150 , 200) Mm.L-1 .The result showed that the salinity significantly reduced all growth parameters for the vegetative and roots parts and yield compared with control treatment plant height , pods length and yield were reduced significantly by C4 ( 200 Mm.L-1 ) . Rising the salinity more than C3 (150 Mm.L-1) didnt effect (dry weight of vegetative plant, dry weight of roots) . (The mean of nodules and pods) (28.5, 15.5 g/plan) (32.8, 8.09) respectively. C4 (200 Mm.L-1) treatment significantly reduced leaves content of (N-P-K) and increased the accumulation of Na+and Cl- (65.12and and 51.77) compare with other treatments.
