This study was carried out in the Permam Erbil governorate from 15th March, 2011 to 15th September, 2011.

to study the response of three species of Festuca lawns: Festuca ovina var hardtop, Festuca arundinacea var palladio, Festuca rubra var bargreen to three shade levels 0, 25%, 75% and three concentrations of Paclobutrazol 0, 1000 and 2000 mg.l-1.

The experimental was preferment by use randomized complete block design.

The results can be summarized as follows: Festuca arundinacea var palladio was superior significantly in accumulative dry weight of clipping growth and dry weight of roots whereas Festuca ovina var hardtop was superior significantly in leaf area and decreased significantly in coverage percentage whereas the three species gave non significant results in the other characters.

The second concentrations (1000) mg.l-1 of Paclobutrazol gave the best significant results for all studies characters except dry weight of root.

Although the dry weight of root and leaf area gives the best significant values when planted in 50 and 0 % shade; the others four characters cannot affected significantly by this factors
