Abstract
The study was conducted at the plastic house of the College of Agricultural Engineering Science, Salahaddin University- Erbil, Iraq, during 2022. To investigate the response of sour orange seedlings to application with bio health at three concentrations (0, 10 and 20 mg. L-1) and three concentrations of Synergic (0, 3 and 6 ml. L-1) on growth characteristics of Sour Orange (Citrus aurantium L.) seedlings local cultivar. A factorial experiment with three replicates was carried out in a Randomized Complete Design (CRD) using three seedlings for each experimental unit. Data were analyzed by (SAS) using the Duncan (ANOVA ،P = 0.05). The obtained results indicated that the growth characteristics were increased by increasing the concentration of the two bio stimulators as compared with control, foliar application of bio health at (20 mg. L-1) caused significant increase in most of the studied parameters. At the same time, foliar application of Synergic fertilization at (6 ml. L-1) gave the highest value of stem high, stem diameter, leaf area, number of leaves /seedling, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight. The interaction between the two bio stimulators caused a significant increase for all growth characteristics, the best treatment was at level (Bio. 20 mg. L-1+ Sy. 6 ml.L-1) as compare with control.
