تأثیر پساب شهری بر غلظت برخی عناصر در ریشه و رشد چغندر قند

In order to evaluate the effect of urban wastewater on some nutrients concentration in root and growth of sugar beet Three treatments irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigation with normal water (control) were compared in a randomized complete block design with three replications at Research Station of Shahrekord University in 2013. The results showed shoot fresh weight and nitrogen and phosphorus concentration significantly affect under wastewater irrigation treatments. The amount of nitrogen and phosphorus was higher under wastewater 8-12 leaf stages than control treatments in sugar beet root. Also the highest shoot fresh weight was belonging to wastewater 8-12 leaf stages treatments. Results showed the intermittent irrigation with the wastewater through proper nutrition could improve plant growth.
