Abstract
The experiment was conducted in a glass house Of the Department of Horticulture and Landscaping in the College of Agriculture, University of Tikrit, for the period from the beginning of December 2012 to the end of May 2013 In order to assess two levels of pH (5,6) of nutrient solution and Five ratios of nitrate : Ammonium ( 0:10 , 1:9, 2:8 and 3:7), as well as Distilled water treatment 0:0 on growth, yield and quality of Gerbera flowers , using randomized complete block design (RCBD). Result shows significant effect to plant growth In the nutrient solution with pH 6 on nutrient solution with pH 5 in two character for Content’s leaf of Chlorophyll and plant height. All ratios of nitrate to Ammonium were feeding area with good vegetative growth, which has agreed quality specifications in length inflorescence compared with out distilled water nitrogen, 2:8 solution at both pH 5 , 6 and 3:7 solution at pH 5 and the solution 1:9 at pH 6 .Inflorescence standard bearer lengths greater than 45 cm and longest vase live compared with 10:0 and 0:0.
