Abstract :

Because of directly and indirectly usage of medicinal plants, organic cultivations of these plants are very important. In order to, study the effect of different concentration of EM Baikal Fertilizer on morphological traits, yield characteristics and essential oil content of Dracocephalum moldavica L. the pot experience was conducted on randomized design whit 5 treatments and 6 replications in freedom place. Treatments were included of different concentration of fertilizer solution (0, 2, 4, 6 and 8 per Litter that 0 as control). The seedling were transplanted to pots at 4 leafy plant stage (about 10 cm height). At 6 leafy plant stage, the treatments used and was continued to the end of the plant life. In each pot, 5 plants kept, and irrigations were two times a week (400 cc) and fertilization was once a week (300 cc). At the end of experiment, at full flowering stage, plant height, inflorescence height, fresh and dry weight of inflorescence and shoot, plant yield, fresh and dry weight of root, essential oil percentage and yield and N, P, K absorption were determined. The results showed significant effect on some measured factors. By increasing of concentration from 0 to 4 gr/l, essential oil content was increased (from 0.5 to 0.77) and more increasing from 4 to 8 gr/l, led to decreasing in essential oil content and the lowest content belong to control treatment. But the most plant yield (16.14 gr/pot) was observed to 2 gr/l treatment. Regarding to absorption of elements, Maximum absorption of Nitrogen (2.56%), Phosphorus (0.013%) and Potassium (0.155%) belong to 2, 4 and 8 gr/l treatments, respectively. In totally, application of 2 gr/l of this organic fertilizer for Dracocephalum moldavica recommend.
