To evaluate the effect of maternal growth environment on the establishment and seed vigor of barley (Hordeum vulgare L.), after warehouse storage, a field experimental was conducted as spilit plot arrangement in complete randomized block design with three replications. The Irrigation treatments, included full irrigation, moderate stress (irrigation flowering stage) and severe stress (irrigation from flowering to harvest), and fertilizer treatments included control (without fertilizer), bio-fertilizer, organic fertilizer, chemical fertilizer, integratedof manure bio-fertilizer with the chemical fertilizer and combination of manure organic fertilizer with chemical fertilizers. Seed vigor and survival after five years of natural storage were measured via vigor test and lipid peroxidation test and finally the grain yield and other plant characteristics were evaluated. The results showed that the moderate drought stress imposed on the mother plant reduced the germination percentage, while the plants which received the integrated bio-fertilizer with chemical fertilizer, had the highest percentage of germination. In this treatment plant height and grain yield increased whereas reduced EC and Lipid peroxidation, while the treatments in which recieved chemical fertilizerand had been under mild water stress, after the storage period, germination and yield component were more vulnerable. The results of seed vigor, establishment and peroxidation of membrane indicated that among of fertilizers treatment imposed on the maternal, the integrated bio-fertilizer with chemical fertilizer under different water stress conditions had the same result and showed more sustainability in seed vigor, yield and storability potential.
