This study was conducted during autumn season of 2016 at Grdarasha research field, Agriculture College, Salahaddin University-Erbil, 434 meters above sea level to determine the effect of planting date and foliar application on the yield and some vegetative growth characters of broccoli. Seeds of Agassi F1 Hybrid broccoli cultivar were planted in the beginning of August 2016 then the seedlings were transplanted to unheated greenhouse in two different periods of time, the first was on 20th October and the second one was 20 days after the first transplanting dates which was on 10th November 2016. Foliar fertilizer PRO.SOL (10+20+30) was also used with three levels (75g PRO.SOL/100 L water), (150g PRO.SOL /100 L water), (225g PRO.SOL /100 L water including control (0 g PRO.SOL/100 L water (spray with distilled water with factorial RCBD design). The result indicated that planting date significantly influenced some vegetative growth characters of broccoli and higher result was recorded for the total yield for seedlings transplanted in November. The average weight of main and secondary heads compared to the control, the main heads of the seedlings transplanted on 20th October produced highest yield while lateral heads recorded lower weight in compare to those transplanted on 10th November. However, the yield of the main heads recorded a better result for those grown in November. Foliar application had also significantly affected both yield and vegetative growth of broccoli. Seedlings sprayed with 150g/100 L water recorded the highest yield and vegetative growth. The interaction of foliar and time had a significant effect of the total yield and some vegetative growth at both times. The best result recorded at both times (October and November) and sprayed with 150g of PRO.SOL/100 L water compare to the control (0 g PRO.SOL/100 L water) and the other foliar application levels.
