In order to study the effect of natural zeolite superabsorbent on yield and yield components of linseed under different moisture regimes, a split plot experiment was conducted in a randomized complete block design with 3 replications at Research Farm of Shahrekord University, Shahrekord, Iran in 2017. The main factor in four moisture regimes included irrigation after 50 (control), 80, 130 and 180 mm evaporation from class A evaporation pan and sub factor, at three levels encompassed no application of zeolite (control), 5 tons zeolite per hectare and 10 tons zeolite per hectare. The results showed that the effect of application of zeolite on vegetation index, number of capsules per plant, number of seeds per capsule, 1000 seed weight, grain yield, biological yield and harvest index was significant at 1% probability level, but this factor had no significant effect on hectoliter weight. Effect of moisture regimes on all studied traits were significant at 1% probability level. The effect of interaction of factors was significant on the number of capsules per plant at the probability level of 1% and on the vegetation index at 5% probability level. With increasing of zeolite superabsorbent under moisture treatments, all studied traits were increased, while application of 10 tons of zeolite per hectare showed the most effect on the growth and yield of linseed in all irrigation conditions (normal irrigation and under drought stress conditions). The highest seed yield (1581 kg ha^-1) of linseed was related to the application of 10 tons of zeolite per hectare and the lowest yield (1331 kg ha^-1) was obtained at the zeolite – free conditions.
