Effect of irrigation regimes on quantitative and qualitative traits of cultivated wild shallot and comparison of these traits with wild shallot in Alashtar natural habitat in Iran

To protect wild shallot plant in natural habitats, where It is endangered due to overexpotation and to produce sustainable medicinal shallots plants, an experiment was conducted on wild shallot a completely randomised block designe with 3 replications and 4 treatments consist of: 50 mm irrigation at planting with 50 mm irrigation at flowering (A), 50 mm irrigation during flowering (B), 50 mm irrigation at planting (C) and control (wild ecotype planted on non irrigated land, D) during 2018-19in Alashtar, Iran. In this research, quantitative traits like biological yield, tuber dry weight and diameter, plant height and qualitative characteristics including active ingredient allicin, crude protein, potassium and phosphorus were investigated in the experimental plots. Along the comparison of the experimental plots, quantitative and qualitative traits of wild shallow were also measured in natural habitat by accidental quadrates and compared to experimental plots. Results indicated the superiority of all quantitative and qualitative traits of the studied treatments in comparison to control and in shallot in the natural habitats. Among all studied treatments, treatment (A) showed superiority in all quantitative traits of compared to 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 its cultivation method leads to stability in the production of shallots and preservation of the diversity of its.
