Abstract

Rhizobium is a genus of symbiotic N2-fixing soil bacteria that induce the formation of root nodules of leguminous plants. To evaluate the effect of Bradyrhizobium on biological efficiency and quality characteristics of mushroom an experiment was conducted in 2008 with mother spawn preparation. Other than control (T1) Bradyrhizobium added directly to wheat corn (T2), added to pure mycelium and added by pure mycelium and incubated by Bradyrhizobium slab at same time (T3).

Added Bradyrhizobium in wheat incubation stage increased positively Ash, Ca, P, K, and protein, and decreased days to primordial initiation in the mushroom samples. Added Bradyrhizobium in Petri culture stage also had an effect of increasing days to primordial initiation, Ca, Mg and protein, but decreasing biological efficiency, Dry matter, Ash, P and K in the mushroom samples. Added Bradyrhizobium in both Petri culture stage and wheat incubation stage did not have any significant effect on total nitrogen in the mushroom samples.
