A field trial conducted at the Experimental Station of the Field Crops Sciences-Department-College of Agriculture, University of Baghdad, during 2010 to study the effect of mutagen nitrous acid, Gibberellic acid, Scarification and soaking in water on seed yield, yield components and quality of three Faba bean varieties(Zaina, Aguadulce and Local). To find out the effect of these factors in different yield,yield components and protein yield and how they respond to the varieties of these factors. Factorial experiment was used according to randomized complete block design RCBD with three replicates to each treatment. The results showed that, soaking seeds in mutagen nitrous acid for 24 hours gave a significant increases of number of branches/plant 12.40, number of pods/plant 29.66, seed weight rate 1.5144(g), seed yield 6629 (kg/ha) and protein yield 1362.7 (kg/ha) compared as a mean of varieties with other treatments. The highest average number of seeds/ pod was 4.456 and 4.489 when seeds soaked in Gibberellic acid at 100,50 ppm, respectively. Local variety was superior in most yield components. significantly showed highest interaction between varieties and treatments 7577(kg/ha), Zaina variety gave the highest seed yield 7577(kg/ha) and protein yield, 1433.1(kg/ha) when soaking seeds in mutagen nitrous acid for 24 hours.
