| Abstract This study was conducted in the nursery of horticulture and landscape design department - College of Agriculture - University of Kirkuk – Iraq during the period 2013-2014, to study the effect of foliar application of humic and boron on growth and yield of two cultivars of strawberry (Fragria x ananassa Duch.). with three levels of humic (0 , 2 , 4)gr.L-1 and three levels of boron (0 , 10 , 20)mg.L-1 with two cultivars of strawberry (Robegames and Fortona) and the effect of interactions of studded factors on growth and yield characteristics. A factorial experiment with three replications was carried out using a Rando- mized Complete Block Design (R.C.B.D.) and obtained data were statistically 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: 1- The variety Rubygem dominated significant on Fortuna in, crown diameter, flowers number, rate of holding flowers, the average of number and weight and size of fruits, The yield average of one plant and hectare, The TSS rate and vitamin C, rate of TSS/TA. But the Fortuna dominated in number of purlins. 2- Foliar application of humic caused significant increase in )flowers number, rate of holding flowers, average of number and weight and size of fruit, The yield average of one plant and hectare The TSS rate and vitamin C, rate of TSS/TA and (NPK) rate in leaves. 3- Foliar application of boron caused significant increase in (flowers number, rate of holding flowers, average of number and weight and size of fruit, The yield average of one plant and hectare, The TSS rate and vitamin C, and (NPK) rate in leaves. 4- The bi-interaction on treatments between the investigated factors showed a positive effect in growth, flowers and yield characteristics. 5- The results of triple interaction between foliar application by humic and boron and strawberry. showed a significant effect in growth, flowers and yield chara- cteristics | ||
