Abstract EN
This study was conducted in lathhouse at the Agricultural Research and Experiment Station of the College of Agriculture - University of Kirkuk during the period from (1/10/2020 - 1/6/2021).To study the response of seedlings of two olive cultivars, Olea europaea L., to some organic and NPK fertilizers, the experiment was applied according to the design of Randomized Complete Block Designs with three replications within the factorual experiments and with two factors: the first factor is the cultivars (Nepali and Manzanillo), and the second factor is the addition of different levels of mineral and organic fertilizers ( Distilled water only (control treatment), (500 mg/L of NPK), (750 mg/L of (NPK), (80 mg/L of Biogreen), (120 mg/L of (Biogreen), (500 mg/L of Biogreen) and (500 mg/L of Biogreen).
Naturwin, 1000 mg/L of Naturwin, 500 mg/L of Total Humic, 1000 mg/L of Total Humic, The results obtained can be summarized as follows: The Nepali variety was the best for its superiority in most of the traits, namely, the percentage of nitrogen in the leaves and the percentage of potassium in the leaves were (2.33) and (2.27) %, respectively.Spraying 750 mg/L of NPK mineral fertilizer led to a significantly excelled on the rest of the treatments.
The percentage of nitrogen in the leaves, the percentage of phosphorous in the leaves, the percentage of potassium in the leaves, the percentage of protein in the leaves and the percentage of carbohydrates in the leaves reached (3.15) and (1.63) %, (3.15) %, (7.70) % and (8.58) %, respectively, The treatment (1000 mg/L Total Humic) excelled in the traits of increase in plant height, increase in the number of leaves, and chlorophyll content in leaves reached (8.20) cm and (13.60) leaves/seedling and (60.60) mg/100 gm.
The bi-interaction between the cultivars and the organic and mineral fertilizer was more than the interaction between 750 mg/l of NPK with the cultivar Nepali in most of the traits, which is the percentage of nitrogen in the leaves The percentage of phosphorous in the leaves, the percentage of potassium in the leaves, the percentage of protein in the leaves, and the percentage of carbohydrates in the leaves were (3.66%), (1.80%), (3.66%), (7.70)% and (9.60)%, respectively.
