Water stress is one of the most important environmental stresses that reduces the growth and yield of crops. Organic fertilizers such as compost and mineral compounds such as zeolite can reduce the negative impact of water stress on plants. The aim of this study was to investigate the effect of irrigation levels (irrigation after depletion of 25, 50 and 75% of field capacity (FC)) and compost treatments (control, 4 ton ha-1, 8 ton ha-1, 4 ton ha-1 compost +10 ton ha-1zeolite and 8 ton ha-1 compost +10 ton ha-1 zeolite) on yield and some physiological traits of quinoa. This study was done in three replications and split plot experiment based on a randomized complete block design at the research farm of Azarbijan shahid Madany University in 2019. In this study, water stress reduced seed yield, minimum seed yield was obtained in irrigation after depleting 75% of FC (2024 kg ha-1), which was 29.8% less than the control. This reduction was partly due to a decrease in the 1000-seed weight. Among enriched compost with zeolite treatments, application of 8 ton ha-1compost, application of 4 ton ha-1compost + 10 ton ha-1 zeolite and application of 8 ton ha-1 compost + 10 ton ha-1 zeolite had a significant effect and increased this trait by 28.9, 36.2 and 32.9%, respectively. Enriched compost with zeolite increased grain yield by increasing the number and weight of seeds. Due to the economic importance of grain yield and quality characteristics and overall plant growth, application of 4 ton ha-1compost + 10 ton ha-1 zeolite can optimally increase grain yield in both low water and full irrigation conditions.
