| Abstract | ||
| This search was conducted in the lath of the Department of Horticulture and landscape – College of Agriculture / Kerbala University for the summer season 2016 on olive seedlings Khadairytype (high Syrian oil type) to see the effect of treatment with licorice and yeast extracts in the growth and development of olive seedlings ; 27 olive seedlings with one year old planted in mixed in 5-kg perforated polyethylene bags were divided into three groups of three replicates and treated with three levels of licorice and yeast extracts (0, 4 and 8) g.L-1. A 3 × 3 experiment was carried out with (R.C.B.D). The results of the statistical analysis showed that the treatment with licorice was 8 g. L-1 was significant in both the number of leaves , respectively, while the treatment of licorice was 4 g. L -1 in the height of the plant by giving the highest rate, while the treatment of licorice (comparison) was 0 g. L-1 and the rest of the treatments in both stem diameter, dry and dry weight of the root mass respectively, while the yeast extract showed a concentration exceeding 4 g. L-1 on the rest of the treatments (plant height, stem diameter, wet and dry weight of total Vegetative and dry weight of the root total) sequentially. The treatment with yeast extract did not have any significant effect on the number of leaves and the area of the leave. The interaction between the study coefficients also showed a significant effect on the different concentrations in all the studied traits, which in turn led to a positive effect of these treatments on the olive seedlings, which led to increased activity and stimulating growth for these seedlings throughout the research period. | ||
