Comparison of the growth of Yucca (Dagger plant) with irrigation by sanitary sewage and drinking water

In this study the difference between physiological and morphological growth of Yucca Elephantipes with irrigation by sanitary wastewater and drinking water was investigated. Morphological variables such as height from the crown to the tail end of the plant, number of leaves, number of stems, leaf length, total leaf dry weight, stem dry weight, number of roots and root size and physiological variables of the plant including Catalase enzyme activity (CAT), Ascorbate peroxidase enzyme activity (APX), Glutathione peroxidase enzyme (GPX) have examined. Irrigation treatments include drinking water and sanitary wastewater. The results show a significant difference in the studied variables between the two treatments at the level of 5%. The highest number of leaves and roots were 64 and 6, respectively, in the treatment of irrigation with wastewater. The number of stems in both treatments was equal to 1. APX in sanitary irrigation and drinking water was 0.62 and 0.71, respectively. The best performance of GPX was related to drinking water irrigation at 0.17. The results also showed that irrigation with sanitary wastewater of Y. Elephantipes, morphological and physiological parameters of the plant had 8% and 2% better performance in the studied variables than similar samples irrigated with drinking water, respectively.
