Author(s):  KHEIRY A., Vaisi m., Sani khani m.
In order to evaluate the effect of micronutrients of iron, zinc and manganese on characteristics of borage, an experiment conducted in the base of randomized complete block design with three replications at University of Zanjan in 2015. Treatments were levels of 0 (control), 3 and 6 per thousand of micronutrients of Fe, Zn and Mn with total of 15 treatments. Foliar micronutrients applied in both stem elongation and flowering stages. Results showed that Highest 1000-seed weight and Seed yield obtained in combination of 3 g/lit iron and zinc (Fe1+Zn1) treatment and the highest number of inflorescences were in treatment of zinc and manganese at 3 g/lit (Zn1+Mn1). Foliar application of iron, zinc and manganese (Fe1+Zn1+Mn1) 3 g/lit, showed the greatest effects on the content of chlorophyll and anthocyanin. Combination of iron and manganese at 6 g/lit (Fe2+Mn2) had the greatest impact on seed oil content and foliar application of iron plus manganese 3 g/lit (Fe1+Mn1) had the greatest impact on the level of Peroxidase. In conclusion, the results showed that the application of micronutrients of iron, zinc and manganese had significant effects on indices such as: Seed yield, Oil percentage, 1000-seed weight, chlorophyll and anthocyanin content.
