Objective: Considering the importance of Mosir as a medicinal-industrial plant, this research was conducted to investigate the different planting and harvesting methods on the quantitative and qualitative characteristics of the Mosir in Lorestan province.
Methods: Experiment in Aligudarz County in the form of completely randomized block design for three years (2017-2020). The methods of planting; manual and machine and distance of planting; 10 and 15 cm in three cropping years. Also the economic performance of different methods was evaluated.
Results: There was no significant difference in leaf width in the studied treatments, but there was a significant difference in plant height at the level of 1%.The average comparison showed that the wet and dry yield in different treatment have significant differences. The highest yield (847g/m2) was in the second year and the machine method and the lowest yield (636g/m2) was obtained in the third year and the manual planting. The dry matter yield at a planting distance of 10cm (185/633 g/m2) and a planting distance of 15cm (178/611g/m2) and the dry matter yield in the machine planting method (199/91g/m2) and manual planting method (164.33g/m2) obtained.The economic evaluation of the results showed that in the machine cultivation method, the average costs are 19% lower than the manual planting method.
Conclusion: Results showed that Increasing the income and reducing the costs of planting and harvesting Mosir in the machine method. Also, machine planting and harvesting of Mosir had a very high speed compared to manual planting and harvesting of this plant.

An experiment was conducted in a randomized complete block design in split-plot arrangement with three replications to find the most suitable location and the planting density of Thymus vulgaris at dry farming condition in seven provinces of Iran. The experimental treatments consisted of plant density (4, 6 and 8 plant/m2), year (1 and 2 years after planting) and location (Tehran, North Khorasan, Isfahan, Kurdistan, Kermanshah, Gilan and East Azerbaijan). The traits comprised of plant height, canopy diameter, dry matter of aerial parts, yield and content of essential oil in full flowering stage. The results revealed that interactions of density, location and year were significant on all studied traits. The highest dry matter (1734 kg/h) and essential oil yield (16.84 kg/h) of aerial parts were obtained in 8 plant/m2 density in Gilan. The maximum and minimum of essential oil content were observed in samples from Isfahan (1.96%) and East Azerbaijan (0.50%), respectively. Based on our findings, it seems that cultivation of T. vulgaris with higher density may cause a higher production of dry matter and essential oil yields under dry farming conditions in Iran.
