| Abstract | ||
| This study was conducted at Agriculture College/University of Kufa on 2011-2012 seasons to evaluation the effect of growth regulator GA3 and liquid organic fertilizer GROMAX on some growth and flower characteristics of Tagetes erecta L. A factorial experiment (3×3) was designed, first factor included three concentrations of Gibberilic acid (0, 150, and 200) mg.L-1 and second factor included three concentrations of liquid organic fertilizer (0, 2 and 4) ml.L-1 according to Randomized Completely Block Design (R.C.B.D.). Results showed that, spraying with gibbrellin, liquid organic acid and the interaction between them illustrated significant effect on vegetative, root and flower growth characteristics, the interaction treatment 200 mg.L-1 of gibberellin with 2 and 4 ml.L-1 liquid organic fertilizer because these concentrations did not different significantly in all studies characteristics of plant height, number of side branches, number of leaves, dry weight of shoot, leaf content of total chlorophyll, leaf content of total dissolved carbohydrates, root number, dry weight of root, length of flower stem, number of flower and flower diameter compared with control treatment (without fertilizer) that gave the lowest values in the same characteristics. | ||
