Ahmad Ismaili Department of Genetic and Plant Production, Faculty of Agriculture, Lorestan University, Iran Journal Article 2019 05 11 To protect the wild shallot plant (<em>Allium</em> <em>altissimum</em>) in its natural habitat, which is endangered due to improper harvesting, and for the sustainable production of shallot, a study was performed on the wild shallot cultivation in a randomized complete block design with three replications and four treatment including (A): 50 mm Irrigation at planting and 50 mm at flowering, (B): 50 mm irrigation at flowering, (C): 50 mm irrigation at planting and (D): control (wild shallots planted in arable land without irrigation) during years 2 (2017-2019) in Alashtar region, Lorestan province. In this study, quantitative traits including biological yield, dry weight, tuber diameters and plant height, and qualitative characteristics including the amount of allicin active ingredient, crude protein, potassium, and phosphorus were investigated. Also, in the natural habitats, quantitative and qualitative traits of wild shallots were measured and compared with the results of the treatments. Results indicated the superiority of all quantitative and qualitative traits of the studied treatments compared to the control and natural habitats. Among all studied treatments, treatment (A) showed superiority in the all quantitative traits compared to the other treatments, control and natural habitat and treatment (B) was more desirable in terms of quality of the active ingredient of allicin than other treatments, control and natural habitat. Therefore, the development and promotion of cultivation method leads to stability of shallots production and preservation of its diversity.
