In order to study the effect of application of different quantities of natural zeolite and soil moisture depletion on yield of corn (Zea mays L.) single grass var. 704, a factorial pot experiment was conducted with 12 treatments and three replications in the experimental field of Agriculture Faculty of Tarbiat Modares University. In this study, zeolite was applied at four levels (0, 2, 4, 8 gr.kg-1 soil) while treatments of soil moisture depletion percentages were at three levels (45, 65, 85 % of soil water) during growing season. Soil moisture of pots was measured by weighting method. After harvesting, also same soil chemical characteristic, leaf area, stem height and leaf and stem total protein percentage were determined. Statistical analyses results indicate that zeolite had a significant effect on all measurement parameters but soil moisture depletion percentage didn’t have a significant effect on leaf and stem total protein percentage .Effect of interaction between zeolite and soil moisture depletion levels was not significant on leaf area and plant height, while had a significant effect on leaf and stem total protein percentage. Based on the results of this research, it was concluded that zeolite application at 8 gr.kg-1 soil with 85% soil moisture depletion produced the greatest water use efficiency.
