| Abstract | ||
| The research was conducted during growing season 2017 – 2018 at Bakrajo Agricultural Research station, Bakrajo, Sulaimani, Iraq in order to study the effect of four kinds of plant growth regulators and plant extracts, yeast bread (3g. l -1), extract of liquorice (5g. l -1), auxin (100 mg.L-1), Gibberellic acid (200 mg. L -1) and control (water) on yield of two Broccoli varreties (Sakata and Agassi RZ). the experiment conduct for RCBD design with three replicates and the comparisons among mean were carried out by Duncan’s Multiple Range test at P ≤ 0.05 .Sakata is superior on Agassi RZ var. in Head weight , head diameter , lateral head No. , plant yield, and total yield and shortest time to harvest which were 248.72g, 13.10cm, 349.53g, 598.25g, 14.96 t.ha-1 and 187.9 ds , respectively. Yeast bread treatment was superior on other treatments and gave maximum head diameter , lateral head weight , plant yield and total yield which were 13.74cm, 421.25g, 655.87g and 16.39 t.ha-1 , respectively. whereas Higher head weight 265.17g obtained from liquorice root and minimum means of yield obtained from auxin treatment. Sakata var. and yeast interaction caused significant increase in head diameter, lateral head weight , plant yield, total yield , and shortest time to harvest which were 14.70cm , 385.39g , 627.06g, 15.68t.ha-1 and 185.28ds, respectively. while Sakata var. and gibberellin interaction caused significant increase in lateral head numbers which was 16.66. | ||
