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.

In order to simulate transplantation, the parameters related to cotton seedling growth are firstly measured in a factorial experiment in a randomized complete block design at Gorgan University of agricultural sciences and natural resources within 2018. The parameters are then utilized in SSM-iCrop2 Model. In the simulation section, four seedling size based on the leaf area (namely 17, 22, 27, and 37 cm-2 per plant) are evaluated in 4 planting dates (15 June, 1 July, 15 July, and 30 July). Results show that in early planting date, seedling transplantation rushes the process of crop maturation for 43 to 49 days. However, this has had no significant effect on yield values (from 453 to 461 g/m2) and net water requirement (312 to 316 mm). The usual sowing date causes the crop to mature between 27 and 38 days (earlier vacant land), whereas seed sowing at this planting date impairs the subsequent crop cultivation. At this planting date, as in early planting, transplanting has no strong effect on the yield (from 444 to 452 g/m2) and water requirement (299 to 308 mm). In a late planting date, seedling transplanting with four seedling sizes between 1 and 5 days results in premature seed germination, even though seed cultivation impairs subsequent planting. At this planting date, transplanting has a noticeable effect on the yield (361 to 441 g/m2), but the amount of pure irrigation (271 to 300 mm) remains unaffected by transplanting.
