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.
