In order to investigate the effect of zeolite on yield and yield components of red beans under drought stress in the field, an experiment was conducted in 2014 in the Takhte Shirin Plantation Company located in the Sahneh, Kermanshah through split plot based on a randomized complete block design with 3 replications. In this experiment, water stress was the main factor with 3 levels, (normal irrigation based on 60 mm evaporation from evaporation basin, mild drought stress after the four-leaf stage based on 90 mm evaporation from evaporation basin and severe drought stress after the four-leaf stage based on the 120 mm evaporation from evaporation basin) considered in the main plot, and zeolite with 4 levels (0, 5, 10 and 15 t/ha) was placed in the sub plots. The results showed that different levels of drought stress caused a significant reduction (P<0.001) in plant height, the number of seed per pod, number of pods per plant, hundred seed weight, seed yield and biological yield traits. Different levels of zeolite also increased the number of pods per plant and plant height (P<0.05), number of seeds per pod, seed weight, seed yield, biological yield and harvest index (P<0.001).The interaction between drought stress and zeolite was not significant in any of investigated attributes.
