This study was carried out at Experimental Station of Agricultural Botany Department, Faculty of Agriculture, Moshtohor, BenhaUniversity during 2009 and 2010 seasons.                 All applied growth substances significantly increased morphological characteristics, nodules number formation, pollen fertility, yield, content of N, P, K, crude protein and carbohydrates in seeds of faba bean plant.                 The treatments of  NAA at 200 or 100  ppm  and salicylic acid at 100 or 50 ppm followed by pp333 at 10 or 5 ppm and Ascorbic acid at 100 or 50 ppm were more effective comparing in this respect. Also, the same treatments exhibited the lowest percentages of flowers and pods abscission.                 In addition, NAA at 200 ppm  and salicylic acid at 100 ppm gave the lowest percentage of abscission, pollen sterility  while gave the highest seeds yield as well as significant differences in the anatomical characteristics.
