| Abstract | ||
| An experiment was conducted in unheated plastic houses that belong to Kufa Technical Institute during the growing season of 2004 .The experiment included (8) treatments , i.e. two okra cultivars (Husainawyia and Hindia) and pinching of growing point or no pinching besides spraying by Atonik Conc. of 15% or nospraying on vegetative growth and yield. ٍSplit-Split-Plot Design was adopted with three replicates . Duncan’s Multiple Range test was used to compare means at 5% .Results showed that the highest values of vegetative growth parameters stem are longth branch number , leave number , leaf area and total dry weight per plant due to the interaction between pinching of growing point and spraying by Atonik in (Husainayia Cv.).The experiment results revealed also,that the highest yield was produced from growing point pinching and spraying by Atonik with (Hindia Cv.) . The largest number of fruits and the highest early yield produced from the interaction between growing point pinching and spraying by Atonik with (Husainayia Cv.) .On the other hand , there were no signifcant differences between the two cultivars when interact with pinching treatment and spraying by Atonik at all studied parameters. | ||
