the comparison of qualitative and quantitative of soybean (glycine max l.) affected by double inoculation with barvar-2 and rhizobium japonicum bacteria at hydro- osmo priming condition

in order to study of the effects of hydro-osmo priming, bio-priming (biological fertilizer (barvar-2) and inoculation with rhizobium japonicum bacteria) on growth & yield of dpx cultivar of soybean (glycine max l.), an experiment was carried out as factorial based on a randomized complete block design (rcbd) with 4 replications in agriculture research station of shahrood university of technology, iran. biological fertilizer including 2 levels (check and using of biological fertilizer) and rhizobium japonicum including 2 levels (check and using of rhizobium japonicum) and priming including 3 levels [(hydropriming, osmopriming induced by peg 6000 and check (unpriming)] were used as treatments. the results showed that interaction between biological fertilizer and rhizobium japonicum significantly affected number of pod per plant, number of seed per plant and oil percentage. interaction between biological fertilizer and priming significantly affected number of pod per plant. grain yield for biological fertilizer consumption was 2897.7 kg/ha and for inoculation with rhizobium japonicum was 2967.2kg/ha. generally, priming, biological fertilizer consumption and inoculation with rhizobium japonicum increased grain yield.
