Study on the effect of wastewater irrigation on nutrient uptake by safflower seeds: (A case Study in Zahedan)

摘要

Given that Iran is facing a shortage of water resources, and recent drought has intensified this shortage, new water resources (wastewater) are taken into consideration so that wastewater consumption has increased day by day. Therefore, the concern about transferring of some of the elements to the plants is taken into consideration. For this purpose, study on the effect of wastewater on plant nutrients absorption was carried out in a completely randomized block design and in the form of split plot in a research farm located in Zahedan during 2013-2014. In this experiment, two types of irrigations including irrigation with regular water (W1), and irrigation with Zahedan refinery treated wastewater (W2) was carried out during whole plant growing season. The results showed no significant difference in seeds heavy metal content. According to our results, wastewater can be used for irrigation, in the absence of proper water resources.
