For study on the effect of different substrates on growth and yield of Gerbera, experiment was carried out as Randomized Complete Block design with 14 treatments and 3 replications. Treatments were as fallow : 1-fine sand,2-peat + fine sand (%25+ %75),3-peat+fine sand( %50+ %50), 4-perlite + peat (%75 + %25 ),5-perlite + peat( %50 + %50 ) , 6-perlite + peat (%25 + %75),7-perlite + peat + expanded clay ( %25 + %70 + %5 ),8- perlite + peat + expanded clay (%50 + %25 + %25 ),9-perlite + peat + expanded clay (25%+ %50 + %25 ),10- peat +expanded clay (%50 + %50 ) , 11-coco peat ,12-coco peat + perlite ( %75 + %25 ), 13- coco peat + perlite (%50 + %50 ), 14-coco peat + perlite + expanded clay (%50 + %25 + %25). Some flower characteristics were evaluated at harvest time. Results of variance analysis and means comparison showed that, 7th treatment was the best of all in some characteristics. In this treatment, at 6 months period, flower numbers, flower diameter, shoot diameter, shoot neck diameter, Flower height and vase life were 10.34(per pot), 12.4 cm, 0.8 cm, 0.58 cm, 54.5 cm and 11.6 days. Whereas for custom substrates (5th. treatment) that used in gerbera production were 7.44 (per pots), 11.3 cm, 0.7 cm, 0.51 cm, 51.6 cm and 10.8 days.
