Abstract

This study was carried out in the wooden canopy of the Faculty of Agriculture, University of Kirkuk, Department of Horticulture and land scape desing in the area of Sayada for the period (1/11/2017 to 1/7/2018) to study the effect of spraying with licorice extract and three levels (0.4.8 gl. -1) and the seed of the ring seeds at three levels (0.3,6 gl-1) in plant growth and content of some plant extracts in two olive tree seedlings (Olea europaea L.). As the data collected for vegetative and root growth, and then took measurements of the vegetative and root and estimated the proportion of chlorophyll and major nutrients (NPK) .The experiment was designed according to the design of complete random segments RCBD as a global experiment and included three factors (3 * 3 * 2) of the extract of licorice and extract of the seeds of the ring and varieties and three replicates and the five seedlings per unit experimental and include spraying parameters of three concentrations of licorice root roots and three concentrations The total number of transactions in each sector was 18 treatments and the number of plants involved in the experiment 270 plants, and the random distribution of the units on experimental units according to the random statistical table and the use of the program SAS SAS for data analysis, adoption of SMT Dunkin's polynomial bar for comparing averages at a probability level of 0.05.The results obtained can be summarized as follows: Spraying with licorice root extract resulted in a significant increase in vegetative growth characteristics of the number of branches(21.9%), leaves (24.1%), leg diameter (11.5%), dry weight (20.7%), leaf area (7.2 cm2), leaf content of total chlorophyll (78.4CCI) Dry for the root total (10.2 g) as well as an increase in leaf content of the major elements) N), (3.1% 3.36 P%) and (3.9% K). Spraying the seed of the ring seeds resulted in a significant increase in vegetative growth characteristics (20.7%), paper size (7.9 cm2), leaf content of total chlorophyll (79.3CCI), root diameter (8.7), Dry weight of the root mass (10.5 g) as well as an increase in the content of the leaves of the major elements (2.94%N) , (0.35%P) and (3.88%K) .The vegetative characteristics of the cultivars were higher than those of vegetative growth (9.8), dry weight (19.4 g), leaf area (6.8 cm2) and leaf content of total chlorophyll (74.3). (7.9) and the dry weight of the root total (9.5 g) as well as the increase of the cultivar category of the Ashri variety in the content of the leaves of the major elements (3.0%N) (3.8%K) Where the Persian variety of the cultivar cultivar was higher than the percentage of phosphorus in the leaves (0.35%P). Bilateral interventions of the studied factors have a significant effect on vegetative and root growth characteristics and the percentage of major leaf elements (NPK). The results of the triple interference between the spray with the licorice extract and the extract of the ring and the two branches of Ashrissi and Khadiri showed a significant increase in vegetative growth characteristics, which led to a significant increase in the number of vegetative branches(26.6%), leaves (28.86%), leg diameter (13.23%), dry weight (24.46%), leaf area (9.62 cm2) and leaf content of total chlorophyll (80.88CCI), the number of root branches (9.63) and the dry weight of the root mass (11.80 g) In addition to increasing concentrations of the major nutrients in the leaves (3.61%N) , (0.37%P) and (4.16%K) .
