This study was conducted durinng November 2017 to June 2018 at the house covered with fiberglass l, Horticulture Dep.

University of Kirkuk , to study the effect of thiamine concentration (0,75,150)mg.L-1and gibberellic acid concentration (0,75,150,300) mg.L-1 on growth and flowering of geranium plant Pelargonium sp, the experiment was conducted as a factorial experiment with Randomized complete Block Design(RCBD) in three replicate, the results show that: the following improvement of growth and Flowering as a result of: 1- The effect was significant in increasing the total content of chlorophyll (29.38)mg.100 g-1 and the content of leaves and flowers of total carbohydrates( 529.17, 444.79) %, respectively, with a lower plant height (51.57) cm, while Sprying with concentration 150 mg.L-1 to increase the plant height rate (61.75) cm and gave the lowest rate of chlorophyll content (21.89)mg.g-1 .

2- The effect of spraying with gibberellic acid at 150 mg .

L -1 was significant in increasing the plant height (60.85) cm and the length of the Flower stem (15.27) cm.

However, it gave the lowest number of inflorescent (2.77) when spraying with a concentration of 75 mg .

L-1gave lowest of plant height (52.70) cm and did not significantly affect the content of the leaves of total chlorophyll and carbohydrates as well as the content of flowesrs carbohydrate.

3- The interaction between spraying with thiamin and gibberellic acid shows that spraying with a concentration of ( 75*75) mg .

L-1 of both factor were significantly affected the increase in leaf content of chlorophyll and carbohydrate ( 33.00 mg.g-1, 629.17%) , and lowest number of inflorescent (2.33) , while the interaction between the two factors at the concentration (0) for gibberellic acid and 75 mg.L-1 for thiamine to increase the number of inflorescent (5.00) , highest content of carbohydrate 524.83% reached form two concentrations (300*150) mg.L-1 for two factors respectively.
