The Effect of Sulphur and Thiobacillus on Nutrient Availability, Vegetative Growth and Essence Production in Lemon Balm (Melissa officinalis L.)

摘要

To study the effect of Thiobacillus, Sulphur and Organic material on vegetative growth and essence production in lemon balm (Melissa officinalis L.) a Complete Randomized Design was conducted in pots in field condition at Shahrekord, Iran on 2008. The factors were ten soil treatments inclusive 200 kg/ha, 400 kg/ha and 600 kg/ha Sulphur, 200 kg/ha, 400 kg/ha and 600 kg/ha Sulphur+Thiobacillus, 200 kg/ha, 400 kg/ha and 600 kg/ha Sulphur+Thiobacillus+ Organic material and without application of Sulphur, Thiobacillus and Organic material. The results revealed that there were significant differences among treatments in Cupper, Zinc, Iron and Manganese content in soil after harvesting and fresh weight, dry weight and number of lateral stems in plants. Differences between Essence content in dry plants in various treatments were significant too. Treatment of 400Kg/ha Sulphur+Thiobacillus+Organic material and Control demonstrated the highest and lowest Cupper and Manganese content in soil after harvesting and fresh weight, dry weight and lateral stems in plants respectively.
