چکیده: Dry violet blue flowers of Echium amoenum (Gol-e-Gavzaban) has long been used

in traditional medicine of Iran. In order to meet the ever-increasing demand of E.

amoenum, for the indigenous systems of medicine as well as for the pharmaceutical

industry, E. amoenum need to be cultivated commercially, but the physical and

chemical situation of the soil fertility to plant production of E. amoenum is not

known clearly. This experiment was conducted based on Completely Randomized

Block Design with three replications and four treatments at Research Station, Faculty

of Agriculture, Ferdowsi University of Mashhad, Iran, in year 2009-2011. Treatments

included: cow manure (30 t/ha), Urban compost (20 t/ha), vermicompost (5 t/ha) and

control. The results showed that studied treatments had significant effect on the most

of studied indices. The highest plant height was obtained in vermicopost treatment.

The highest main and lateral branches numbers and number of flowers per plant

were obtained in cow manure and vermicompost. In addition, the highest and lowest

fresh flower yield and dry flower yield were observed at second and fourth harvest,

respectively. Also, the highest and lowest number of flower per 5 g of flower obtained

at fourth and first harvest, respectively. Hussien [3] reported that some of growth

indices, dry and fresh yield of Dracocephalum moldavica increased by application

of compost [3]. It has been stated that growth indices of plants increased through

improving of physical and chemical characteristics of soil by application of organic

manure [1, 2]. Tahami Zarandi et al.[4] found that the maximum dry and fresh yield

of Ocmimum basilicum were obtained at third harvest [4]. Overall, our results showed

that studied organic manures have positive effect on E. amoenum petals production.
