Abstract

Background and Objectives: Increasing population along with the global crisis of Fresh Water resources necessitate the use of Unconventional Water resources in agriculture as the largest consumer of Fresh Water, especially in arid and semi-arid regions. Since one of the important goals in sustainable agriculture due to the water resources crisis is to increase water use efficiency, therefore, it is necessary to use techniques to achieve this goal. Due to the scarcity of high-quality water, the use of Unconventional Water (municipal Wastewater) is increasingly under consideration. Materials and Methods: An investigation was done to evaluate effects of different regimes of urban Wastewater on performance and yield components of Quinoa plant (cv. Titicaca), at Research Greenhouse of Ferdowsi University of Mashhad, during 2017-2018. The research was based on completely randomized design with 3 replications in greenhouse conditions and in pots. Five applied treatments were urban Fresh Water, urban Wastewater, Alternate Wastewater and Fresh Water, Mixture of 50-50 Wastewater and freshwater and Subterranean Irrigation with urban Wastewater. Physical and chemical properties of irrigation water and of soil were determined before experiment. The obtained data analyzed using statistical software of SAS (Ver. 9. 0) and the means were compared using LSD test at 5% percent levels. Results: The results showed that the treatments were effective on number of leaves, shoot fresh weight, plant height, SPAD index and leaf area at 1% significance level (P<0. 01), but on number of branches, shoot dry weight and stem diameter at 5% significance level (P<0. 05). According to the results of the study, the use of urban refined Wastewater increased all the traits. The results showed that the highest and lowest of shoot fresh weights (13. 9 and 7. 2 g), shoot dry weights (0. 98 and 0. 46 g), leaf number (86. 3 and 51. 3), branches number (10 and 6), height (49. 7 and 25. 9 cm), leaf area (218. 8 and 135. 8 cm2) and grain yield (24. 23 and 17. 8 g) in Subterranean Irrigation and control treatment, respectively. Conclusion: The urban Wastewater, Alternate, Mixture of 50-50 and Subterranean Irrigation treatments resulted in an increase of 62. 5%, 37. 5%, 58. 3% and 93. 1% of total yield, respectively. Furthermore, the results of the experiment showed that the use of refined sewage water for irrigation of Quinoa crop can increase the yield of Quinoa, decrease the cost of supplying and using fertilizers.
