The use of new technologies for enhancing water and nutrient use efficiency will become more important over time, especially in regions with limiting water availability. Application of superabsorbent polymers and slow release fertilizers (SRF) are two proper methods to enhance water and nutrient use efficiencies, decrease the cast of chemical fertilizers and decrease the possibility of groundwater pollution. Superabsorbent hydrogels absorb and store water hundreds times of their weight and improve some soil properties. In this research, the effect of superabsorbent polymer on the yield performance, growth indices (weight of wet and dry shoot and length of shoot) ,water use efficiency and N, K, Fe and Zn uptake of a nursery plant ( Cucumis sativus var. Gavrish), was evaluated. The greenhouse trial was conducted as a completely randomized factorial design in which the treatments were two soil textures (sandy and clay loam), three irrigation regimes consisting 50%, 75% and 100% Etc and the hydrogel treatments were soil containing 0, 4, 6 and 8 g/kg hydrogel. The results of statistical analyses showed that treatments have significant effects on all of measured parameters. Maximum yield was obtained in clay loam soil with 4 g/kg polymer and 100% irrigation. The soil texture didn’t have any significant effects on yield, water use efficiency, weight of wet and dry shoot, but was effective on the length of shoot. Averages of yield and water use efficiency in sandy soil were higher than clay loam soil but growth indices were higher in clay loam soil. All parameters decreased significantly by deficit irrigation but No significant difference, was observed in water use efficiency by 25% deficit irrigation. Averages of all parameters in 4 g/kg polymer level were higher than no polymer and 6 and 8 g/kg polymer levels. Decrease of irrigation led to increase of N, K, Fe and Zn uptake. With Increasing of polymer application, N and K uptake increased but it didn’t influence Fe and Zn uptake. Hence, use of 4 g/kg superabsorbent polymer Superab A200 in a light texture soil and without stress or 25% deficit irrigation is recommended to achieve the best marketable yield and desired water use efficiency. Also in this research, a kind of iron slow release fertilizer was made and its release pattern was evaluated. Three polymers Ethyl Cellulose (EC), Glycerol Monostearate (GMS) and Compritol 888 ATO, mixed with another exipients such as Avicel and Lactose (fillers) and the pellets were made by Extrusion -Spheronization method. The dissolution test carried out to determine the release rate versus time. The results showed that, pellets with Compritol 888 ATO releases iron ions slower than EC and GMS. In a long time experiment, release percent reached to 90% after 7 days. To achieve more slowly release pattern, the pellets were coated with Ethylene Vinyl Acetate (EVA) polymer. The Dip Coating method was used and the pellets
