Borago is one of the plants of Boraginaceae family. To study the effect of Fe, Zn, Cu and Mn foliar applications in Borago on yield and essence production, the investigations were performed in complete randomized block design with 3 replications at 2011 and 2012 in Shahrekord, Iran. Results showed that Fe, Zn, Cu and Mn had the significant effectiveness in percentage of essence, DPPH, carotenoids, flavonoids, phenols, weight of fresh and dry root matter, number of flower, and weight of dry and fresh of flower and weight of dry and fresh shoot matter. Combinations of 400ppm of Fe, Zn, Cu and Mn (Fe3Zn3Cu3Mn3) produced the greatest amounts in most of measured characters. The most of phenols, carotenoids and flavonoids was 75, 0.6, 0.6 mg/100 gr flower dry matter and 81, 0.8, 0.62 mg/100 gr flower dry matter in primary and secondary year respectively. The most weight of dry flower and number of flower per plant were 14.8, 16.8 gr and 10.9, 13.9 in 1st and 2nd year and made by Fe3Zn3Cu3Mn3 treatment.
