Abstract

An experiment was conducted under greenhouse condition at Bam region in 2010. The experiment design was factorial arranged in RCBD with four replications. Fertilizer factor(A) has four levels: control (without use microelements), application of Fe sulfate, application of Zn sulfate and application of Fe sulfate+ Zn sulfate and growing media factor (B) has four levels : cultural soil (sandy roses texture), combination of washed grand and cultural soil in 40 to 60., combination of pittmos (40%) + perlite (20%) + cocopitt (40%) and combination of pittmos +washed grand in 60 to 40. Fertilizers was used in 0.35 doses and with application of microelement fertilizers, net water was used in control. Microelements was used in four stages in all growing media (except control). Results showed that growing media and application of microelements had significant effect on measured traits. The highest length of roots, fresh and dry weight of roots, fresh and dry weight of shoots, the number of leaf in plant, leaf area and essential oil percentage, obtained from application of Fe sulfate + Znsulfate and combination of pittmos+ washed grand in 60 to 40 and the lowest of this traits, obtained from control and culture soil.
