This field research was carried out to study the effect of boron foliar application at different growth stages on morphological parameters of wheat Alex variety at Didactic Station, Timisoara, Romania during the year 2012-2013. The trial was laid out in a randomized complete block design (RCBD), consisted of three replications with the following treatments: T1 control (only received distilled water spray), T2 (B 0.3% at ZGS22), T3 (B 0.3% at ZGS41) and T4 (T2+T3) as form boric acid. Foliar solution of B was sprayed with a hand held pump sprayer at the rate of 400 L ha"1 on plant foliage. Experimental results revealed that the foliar application of 0.3% boron as a H3B03 at different growth stages at ZGS22 and ZGS41 significantly increased plant height, spike length (cm), number of spikes m"2 and number of spikelets per spike which were over the control. Best results were obtained when B was applied at 0.3% at ZGS22 and ZGS41 (T4), which gave significant increase in plant height, spike length (cm), number of spikes m"2 , and number of spikelets per spike as compared with the control treatment. These parameters were increased by 11.11%, 15.38%, 12.81% and 17.30%, respectively.
