The present study has been made in University of Mosul/ College of Science/ Department of Biology to investigate the effect of adding the residues of Cephalaria sp., Brassica sp. and Hordeum sp. weeds at concentration (0,2,4,6) % (w:v) in seed germination and seedling growth in Vicia faba L, and Lens culinaris medik, the adding of (2mg/kg) of (Brassica sp.) residues caused the highest percentage of seed germination (70%) in Vicia faba L. adding (4 mg/kg) of (Cephalaria sp.) residues caused the highest percentage of stimulation in length (32.7 and46.8 cm) of the shoot and roots in Vicia faba L., the highest percentage of stimulation in dry weight for the vegetative in Lens culinaris medik at the adding of (4 mg/kg) of (Cephalaria sp.) residues, while the highest percentage of reduction in dry weight (5.5 mg) of the roots partin Vicia faba L. at the adding of (6 mg/kg) of (Hordeum sp.) residues, and the highest percentage of stimulation in the number and dry weight of nodule in Vicia faba L(2.23)kg. at the adding of (4 mg/kg) of(Cephalaria sp.) residues.
