In arid and semi-arid regions, such as Iran, it is inevitable to use wastewater for irrigation. In addition, it is important to apply minerals like zeolite in order to reduce adverse effects of wastewater usage and improve plant growth. Regarding to this purpose, this research was conducted to evaluate the effect of wastewater and zeolite on cotton yield and yield components. Therefore, a randomized complete block design based on split plot was considered during 2016 in Torbate-Heidarieh, Iran. The treatments were consisted of two irrigation types (I1: well water and I2: wastewater) and two zeolite rates (Z0: no application and Z1: 4% w/w) in three replications. Results revealed that irrigation type had significant effect on stem diameter, plant height, number of leaf, first cotton yield (P<0.01), boll weight and total cotton yield (P<0.05). Zeolite application had significant effect on cotton height, first cotton yield, boll weight and total cotton yield (P<0.01). Interaction effect between zeolite application and water type had significant effect on cotton height, boll weight, total cotton yield (P<0.01), stem diameter and number of leaf (P<0.05). Maximum of stem diameter index, plant height and number of leaf were belonged to I2Z0 and I2Z1treatments, respectively.In addition, maximum of boll weight and first cotton yield were related to I1Z1 and I2Z1 treatments, respectively. Also, I2Z1 and I1Z treatments had maximum total cotton yield. So, these results showed that application of wastewater and zeolite can be effective on yield and yield components of cotton.
