Assessment of K+, Na+ and Cl- Content in Rice Tissues and Soil Irrigated With Wastewater
Abstract
In recent years, many studies have been devoted to investigating consequence of wastewater usage in irrigation. Herein, assessment of wastewater irrigated rice crop (selected rice cultivars such as, Shandar, Shua-92 and Sarshar) irrigated water and cultivating soil samples of Tandojam, Hyderabad city and its vicinity were selected for analysis. In this study, pH, EC, Na+, K+ and Cl- ions were observed for wastewater, irrigated rice cultivars and soil, and compared with canal water irrigated rice cultivars and soil. The application of wastewater resulted an increase in Na+, K+ and Cl- concentration in rice cultivars tissues as compared to canal water rice cultivar. The obtained results have shown that wastewater is not suitable for edible crops like, rice irrigation, due to high alkaline pH, EC value, and higher K+, Na+ and Cl- ions concentration in this water.
