This experiment was conducted in Agriculture College/University of Kufa in 2011-2012 seasons to study the effect with spraying different concentrations of organic fertilizer NADA LAND and Gibberellin on some vegetative and flowering characteristics of aster plant Aster amellus L.

Factorial experiment (3^3) was conducted by using three replicates.

The first factor was three concentrations of organic fertilizer (0, 2, 4) ml.L-1 and the second was three concentrations of Gibberllic acid (0, 100, 200) mg.L-1.

Results showed that the addition of liquid organic fertilizer and Gibberellin and their interaction had significant effect on vegetative and flowering characteristics but the the highest average of plant height, number of branches, number of leaves, leaf area, dry weight of shoot, leaf content of potassium, chlorophyll, phosphorus, total dissolved carbohydrates, height of flower stalk, flowers number and flower diameter realized at the interaction of 4 ml.L-1 of organic fertilizer with Gibberellin of 200 ml.L-1, while control gave the lowest values of these characteristics.
