A field experiment was carried out at first research station (Um- alaakf ) field crop department / Collage of Agriculture/ University of al- Muthanna in season 2014-2015. The study was investigated the effect of spraying zinc and boron in different concentration (0, 25, 50, 75, 10 ppm Zn) and ( 0, 20, 40, 60, 80 ppm B)resp. on characters of growth and yield components of faba bean (Vicia faba L.). The experiment was designed by factorial experiment in R.C.B.D. with three replications. The result showed significant effect in different levels of spray zinc and boron , the concentration (100 and 75 ppm Zn) was superior in branches per plant, pod plant−¹ , seed number plant−¹, yield plant−¹(gm) it was (7.60, 7.13 branch plant−¹ , 12، 11.73 pod plant−¹ ، 3.86, 4.40 seed number plant−¹ ، 92 , 92.07 yield plant−¹(gm) ) frequency. Whilst the concentration 75 ppm zinc was superior in plant height, pod length, 100 seed weight ( 82.39 cm, 23.29 cm , 5489 gm) frequently and was significant with other levels, however the boron levels (60, 80 ppm) was superior in plant height, branch Plant−¹, pod length, pod plant−¹ ,seed pod−¹, yield plant−¹. It reach ( 80.25, 78.64 cm، 5.33,5.40 branch Plant−¹ ،
21.53, 21.85 pod length (cm)، 9.40,9.93 pod plant-−¹ ، 3.67, 4.06 seed pod−¹ ، 84.53, 86.40 yield plant−¹ (gm) ) frequency. The level of boron 60 ppm was significant superior in 100 seed weight it was 42.10 gm. The interaction boron and zinc showed high significant the combination ( Zn4+B4) was superior in most of characters, The pod plant−¹ was 5.67 ,99.67 gm yield plant−¹ and 100 seed weight reach 89.63 gm.
