Abstarct: Water deficit is one of the most important stress factors limiting the crop production in the world. Superabsorbent polymers (SAP) are new functional polymer materials containing strong hydrophilic groups that can absorb and retain extremely large amounts of a liquid relative to their own mass. Chickpea is a resistant plant to drought and salinity stresses and have protein. In order to study the effects of zeolite and organic matters as soil amendment on growth, yield and yield components of chickpea, a field experiment was conducted as split plot layout baxsed on a randomized complete block design with three replications at the Agricultural Research Station, University of Sahrood during growing season of 2017-2018. Three irrigation levels (such as full irrigation (FI), cutting off irrigation at 50% seed filling stage (CS) and cutting off irrigation at 50% flowering stage (CF)) and four levels of soil amendments (including zeolite (Z), manure (M), 30%Z+ 70%M and 70%Z+ 30%M) were considered as main and sub plots, respectively. The results showed that the effect of soil amendment was significant on plant height, dry matter accumulation, dry weight of leaf and stem, yield, yield components, chlorophyll, EC, harvest index, seed protein percentage and seed protein yield of chickpea. Also, irrigation had significant effect on number of pods per plant, biological yield, harvest index, seed protein percentage and seed protein yield of chickpea. Interaction effect of soil amendment and irrigation had significantly positive effect on proline content, seed yield, biological yield, harvest index and seed protein percentage of chickpea. The factors had not significant effect on urease enzyme activity and pH of soil. Totally, soil amendment improved growth and yield of chickpea under water deficit conditions.
