The feasibility of using Caspian seawater to irrigate Persian leek (Allium persicum L.)

Increasing population growth along with the freshwater resources global crisis necessitates the use of unconventional water resources in agriculture, as the largest fresh water consumer, especially in the arid and semiarid areas. The goal of this study was to effect of irrigation with conjunctive Caspian seawater and fresh water on yield and yield components of Persian leek (Allium persicum L.) in greenhouse condition. The research was done based on completely randomized design including three replications as pot planting in Gorgan University of Agricultural Sciences and Natural Resources during 2015. The treatments included four levels (mixture of sea water tap water, alternate, half alternate and tap water), respectively. The results inducted that the effect of different irrigation regimes on chlorophyll, shoot fresh weight, plant height, number of leaves per plant, root fresh and dry weight were highly significant (P
