| Abstract This studywas conducted in the nursery of horticulture and landscape design department - College of Agriculture - University of Kirkuk - Iraq during The period from mid-April to mid of October 2013, to study the effect of foliar application of agrihumateand urea with three levels (zero,500,1000)mg.L-1on some vegetativeand root characteristicsand leaves contents of carbohydrates of three cultivars of Olive (Olea europaea L.) (Ashrasy, Bashiqy and Manzanillo). A factorial experiment with three replications was carried out using a Randomized Complete Block Design (R.C.B.D.) and obtaineddata were statis- tically analyzed by using (SAS V. 9.0) system, and Duncan’s Multiple Range Test at P> 0.05 used to compared the means of treatments. The results obtained in this experiment could be summarized as follows:- Foliar application of agrihumate in concentrations of (500,1000) mg.L-1and urea in concentration of 1000 mg.L-1 caused a significant increase in (stem height, leaves area, shoots and root dry weight, leaves contents of carbohydrates). Manzanillo cultivar dominated in (shoots dry weight). Whereas Ashrasy cultivar had significant increase in (leaves area). But the cultivars not affected (stem height). Also Manzanillo and Ashrasy cultivars dominated on Bashiqy cultivar in (root dry weight) Whereas Ashrasy dominated in carbohydrates contents. The bi-interaction and triple interaction on treatments between the investi- gated factors showed a positive effect in studied characters. | ||
