Investigation the Effect of Unconventional Water on Yield and Yield Components of Quinoa

Since the agriculture field is the main water consumer, using techniques in order to increasing water use efficiency is necessary. Due to the limited freshwater, farmers have to use unconventional water, such as Wastewater, Fishery Wastewater and Saline water. In this study, Four Quality of water is evaluated on yield and yield components of Quinoa (CV. Titicaca). the research was done based in completely randomized design including 3 replications as pot planting in Ferdowsi University of Mashhad in Greenhouse conditions, during 2017-2018. In this study, four irrigation regimes existed of (fresh water, Wastewater, Fishery wastewater and saline water). The results showed that effect of different quality of water on shoot fresh and dry weight, stem diameter SPAD index and leaf area was significant at 1 percent level (P<0.01), but plant height and branches number was significant at 5 percent level (P<0.05). in this study, all of this parameter decreased significantly with irrigation by saline water. in this study, increased all of this parameter with irrigation by wastewater and fishery wastewater.
