Background and objectives: 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. Soil physical condition is one factor that can limit crop production. Poor soil physical condition can restrict water intake into the soil and subsequent movement, plant root development and aeration of the soil.
Materials and methods: Investigation the effect of different water quality and Zytonic on yield and yield components of Quinoa (cv. Titicaca). the research was conducted as a factorial experiment based on completely randomized design including 3 replications as pot planting in Ferdowsi University of Mashhad in Greenhouse conditions, during 2017-2018. In this study, water quality included (freshwater, wastewater, fishery wastewater and saline water) and Zytonic included (0 and 1 kgm-2).
Results: The results showed that effect of different water quality on leaf number, branches number, shoot dry weight, plant height, stem diameter, SPAD index, and leaf area was significant at 1 percent level (p < 0.01), but on shoot fresh weight was significant at 5 percent level (p < 0.05). The results showed that effect of different zytonic levels on leaf number, and shoot dry weight, stem diameter, SPAD index, and leaf area was significant at 1 percent level (p < 0.01), but on shoot dry weight was significant at 5 percent level (p < 0.05). Interactions between water quality and zytonic levels leaf number, and shoot dry weight was significant at 1 percent level (p < 0.01), but on branches number, shoot fresh weight, and stem diameter was significant at 5 percent level (p < 0.05).
Conclusion: 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. Wastewater and fishery wastewater has resulted to increasing of shoot fresh weight 6.9 and 12.9 percent and shoot fresh weight 13.2 and 16.9 percent, respectively. Saline water has resulted to decreasing of shoot fresh and dry weight 31.2 and 39.6 percent, respectively. Zytonic has resulted to increasing of shoot fresh and dry weight 41.4 and 16.3 percent, respectively. increasing of shoot fresh weight 6.9 and 12.9 percent and shoot fresh weight 13.2 and 16.9 percent, respectively. Saline water has resulted to decreasing of shoot fresh and dry weight 31.2 and 39.6 percent, respectively. Zytonic has resulted to increasing of shoot fresh and dry weight 41.4 and 16.3 percent, respectively.
