The effect of conjunctive irrigation with seawater and fresh water on biochemical properties and water use efficiency of Dill (Anethum graveolens L.)

The goal of this study was to investigation the effect of conjunctive irrigation with seawater and fresh water on biochemical properties and water use efficiency of dill (Anethum graveolens L.) in greenhouse condition. In this study, five conjunctive uses of seawater and fresh water are evaluated on yield and yield components of dill. 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 2016. In this study, five irrigation regimes existed of irrigation with one-third of sea water with tsp water, irrigation with half seawater and then one more half with fresh water, alternate irrigation with seawater and tap water, conjunction irrigation. The results inducted that the effect of different irrigation regimes on total chlorophyll and Cl-of leaf were highly significant (P
