Due to the availability of limited water resources in the country, it is necessary to use unconventional water. On the other hand, application of minerals such as Zeolite (Zo) is necessary to simulate plant growth and reduce the harmful effects of wastewater. The present study was conducted to investigate the effect of irrigation by wastewater with Zo on cotton (Gossypium herbaceum) based on a randomized complete block design with factorial arrangement in Torbat Heydarieh, 2014. For this purpose, irrigation water treatment at 2 levels (I1: irrigation with normal water and I2: irrigation with effluent) and Zeolite (Zo) treatment at 2 levels (Z₀: No Zo application and Z₁: application of K⁺ Zeolite at 4% weight) were considered with three replications. The results showed that the irrigation water type had a significant effect on the seed index, yield, cotton weight, number of leaves per plant and the lint percentage. The rate of Zeolite (Zo) did not show any significant effect on any traits, such as Kiel percentage, seed index, cotton weight, number of leaves per plant and cotton yield. The interaction between the irrigation water and the amount of Zo had a significant effect only on the number of leaves per plant. The results also showed that the highest lint percentage, cotton weight and number of leaves per plant in the irrigation by the effluent with No Zo application (I₂Z₀) treatment with the values of 64.3 and 11.23 gr and 36.3 numbers and the lowest values for the seed index, yield and number of leaves per plant in irrigation by normal water with No Zo application (I₁Z₀) were obtained with the values of 0.52 and 78 gr and 24.8.
