Abstract
A field experiment was conducted to investigate the effect of a symbiotic nitrogen fixing bacterium Bradyrhizobium japonicum strain TAL-102 and a commercial biofertlizer EM (effective microorganisms) on growth, nodulation and yield of soybean [Glycine max (L.) Wilczek] in soils amended either with farmyard manure or Trifolium alexandrinum L. green manure @ 20 tons ha -1 each. In green manure amendment, B. japonicum inoculation significantly enhanced number and biomass of nodules resulting in a significant increase of 27, 65 and 55% in shoot biomass and number and biomass of pods, respectively. In farmyard manure amended soil, B. japonicum inoculation significantly enhanced fresh biomass of nodules. As a result a significant increase of 45 and 47% in shoot biomass and number of pods was recorded, respectively. Generally, the effect of sole EM application on various studied parameters was insignificant in both the soil amendment systems. Combined application of EM and B. japonicum in green manure amended soil reduced shoot growth and number of pods as compared to sole B. japonicum inoculation. Conversely, in farmyard manure amendment, plants co-inoculated with B. japonicum and EM exhibited highest and significantly greater shoot biomass, and number and biomass of pods as compared to all other treatments. The present study concludes that soybean yield can be significantly enhanced by the application of B. japonicum and EM in farmyard manure amendment.
