Addition of non-symbiosis microbial consortium and arbuscular mycorrhizal to increase growth and crop production of jack beans plants (Canavalia ensiformis L.)

This research aimed to determine the promoting effect of non-symbiotic microbial consortium and arbuscular mycorrhiza on growth and crop production of the jack beans plants (Canavalia ensiformis). Microbial diversity of non simbiotic microbes consisted of Azotobacter sp, Azospirillum sp, Bacillus sp, Pseudomonas sp, Saccharomyces sp and Cellulomonas sp and propagules arbuscular mycorrhiza of Glomus sp and Gigaspora sp. Treatment conditions were addition of non-symbiotic microbial consortium for different doses, addition of arbuscular mycorrhyzal propagule for various doses and combined treatment to the plant. The parameters observed were height of plant, weight of plant, weight of root, length of root, number of pod, weight of pod and weight of dry seed, Relatively Agronomic Effectiveness (RAE) value and mycorrhyza infection. The results showed that the use of non-symbiotic microbial consortium and abuscular mycorrhyza and combination of them, the so called biofertilizer, was significant in increasing of crop growth and productivity.
