In order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out Gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. In this experiment two level of super absorbent polymer namely Aquazorb such as control and 50 kg/ha and 10 different combination and amount of chemical, vermicompost and prolific phosphorus 2 were applied. Treatments without applying any fertilizer (Control), 100 percent chemical fertilizers (B1), 50 percent of chemical fertilizers and bio- fertilizers inoculation (B2), 50 percent and 6 tons of vermicompost (B3), 50 percent of fertilizer and 12 tons of vermicompost (B4), inoculated with bio-fertilizer and 6 tons of vermicompost (B5), inoculated with bio-fertilizer and 12 tons of vermicompost (B6), 6 tons of vermicompost (B7), 12 tons of vermicompost (B8) and inoculated with bio-fertilizer (B9), respectively. The results indicate that inoculation with bio-fertilizers and 50% chemical fertilizers (NPK) recommended in the presence of superabsorbent polymers (B2), had the highest yield (4100 kg/ha) and the control treatment had the lowest performance. Similarly, in many traits of yield components, B5 and B6 treatments had the largest amount of data that demonstrate the positive impact of the integration of bio-fertilizers and vermicompost on them.
