The average phosphate fertilizer gave the highest significant difference at the 5% level in the percentage of potassium in leaves: as for dual interaction treatment between Iranian variety and spraying with 25 mg.l-1 of boron, the highest significant difference in plant height characteristics, vegetative growth wet weight, total chlorophyll content, single leaf areaand the percentage of each element. Nitrogen, protein, and boron (ppm), and the dual interaction treatment between Argentinian variety and fertilization at a 20 kg.ha-1rate of phosphate fertilizer had produced highest significant difference in the characteristics of the number of lateral branches of each one of the plants. The dual interaction treatment between spraying with boron at a 25 mg.L-1concentration and fertilizing with an average of 20 kg of phosphate fertilizer had the highest significant difference at the probability level of 5% for the traits for most of the studied traits, and treatment of the triple interaction between each of Iranian variety and spraying with 25 mg.l-1 boron and the fertilization at a 40kg. ha-1rate of phosphate fertilizer had the highest significant difference in plant height characteristics, vegetative growth wet weight, total chlorophyll content in leaves, leaf area(cm2), and boron content ppm. 1) Part of MSc.
