Abstract :

This research in order to study the effects of the effect of bio fertilizer and magnesium sulfate on the components of essential oil of Satureja hortensis L., was performed. The experiment was based on randomized complete block design with 6 treatments and 3 replications. The factors consisted of 2 levels of inoculation with fertilizer barvar 2 and non-inoculation) and 3 levels spraying of magnesium sulfate (0, 2 and 4 g). The traits were plant height, number of stems, stem diameter, dry weight, yield, essential oil percentage and essential oil yield. The results of analysis of variance showed that the highest yield was obtained by inoculation with fertilizer barvar 2 and 4 g magnesium sulfate, with a mean of 80/50 kg ha-1, and the lowest yield in non-fertilized treatment with fertilizer barvar 2 and the non-application of magnesium sulfate with a mean of 23 kg ha-1 was obtained. The results showed that the highest percentage of essential oil was obtained by inoculation with barvar 2 and 4 g magnesium sulfate with an average of 1.02 kg ha-1 and the lowest percentage of essential oil without Fertilizer barvar 2 and non-application of magnesium sulfate with the average was 0.64 kg ha-1. In general, the results of this experiment showed that in order to produce more essential oil and to have more dry yield, it seems appropriate to inoculate with barvar 2 and 4 g magnesium sulfate.
