Treatments included foliar application of four rates of boron 0, 0.5, 1.0 and 2.0 Kg B ha-1 applied in 2, 4, 6 and 8 applications in a RCBD experiment with 3 replicates. Results indicated that, plant height, numbers of branches per plant, green pod and dried bean seeds and water use efficiency (WUE) increased with increasing amount of boron applied and number of applications. Faba bean dried seed yield increased from 1.63 Mg h-1 for control to 3.82 for 2.0 Kg B h-1 applied in 8 split applications. Values of WUE ranged between 0.44-0.97 Kg dried beans and 2.46-4.11 Kg fresh (green) pods m-3 water applied. Results of nitrogen and phosphorus percentage (% of dry weight) and as uptake by beans increased with increasing rate of boron applications. Boric acid Fertilizers productivity ranged from 64 to > 700 Kg dried bean seed for each Kg of boric acid applied. This signifies the economic justification for this application. Therefore, it can be concluded that proper boron application with good crop management can achieved good productivity and high WUE under middle of Iraq conditions.
