This study was conducted in Agricultural College/ Dohuk University during the period 11th Apr and 11th Jun 2010.

The objective was to study the best planting depth (0, 1, 3) ml for ten cultivars of Lawns Poa pratensis var barimpaia, Cynodon dactylon var cd4, Cynodon dactylon var panama, Lolium perenne var adeline, Lolium perenne var barblack, Lolium perenne varbartwingo, Festuca orundinacea var barlexas 2, Festuca Rubra commutate var bargreen 2, Festuca arundina var palladio, var hardtop, Festuca ovina duriuscula.

Results showed significantly increase in germination percentage, dry weight of plant, pure live seed percentage, and germination speed as coverage thickness decreased.

All Festuca cultivars show significantly increase in germination percentage, pure live seed percentage, and less germination speed while Lolium cultivars give the best result in dry weight of plant and number of vegetative branch when compare with the other cultivars.

The interactions between the two factors had a significantly effect for most of studied characters.
