Effect of Foliar Spray of Ascorbic Acid, Zn, Seawee d Extracts (Sea) Force and Biofertilizers (EM-1) on Vegetative Growth and Root Growth of Olive (Olea Europaea L.) Transplants cv. HojBlanca

The study was conducted at the nursery of Malta sta tion/ Duhok. Kurdistan region-Iraq, during the season 2011 to st udy the effect of Ascorbic acid(Vitamin C), Zn, sea weed extracts(Sea force) a nd Biofertilizers (EM-1) on vegetative growth and root growth of two year old o f olive cultivar (HojBlanca), the transplant were sprayed with four levels of Ascorbic acid (0, 250,500 and 750mg.l-1) by using Vitamin C (20 %)as a source of Ascorbic acid and three levels of Zn(0, 15 and 30mg.l-1),three l evel of sea weed extracts( Sea force) (0,1 and 2 mg.l-1)and three level of biofert ilizer (EM-1) (0, 0.5 and 1 mL.L-1) Foliar application of Sea force at 2ml.l-1 increased significantly plant height, leaf number and leaf dry weight. Increasing Zn level up 30mg.l-1 significantly increase stem diameter(mm).However 50 0mg.l-1 Ascorbic acid increase significantly leaf area and shoot number/p lant also Ascorbic acid at 750mg.l-1significantly increase total chlorophyll cand root dry weight. Foliar application of (EM-1) at 0.5ml.l-1 increased significantly average shoot length also (EM-1) at 1ml.l-1 significantly increas e shoot dry weight and root length.
