Response of soybean to bradyrhizobium inoculation and diammonium

A field experiment was conducted to assess the response of Soybean (Glycine max. [L.] Merr.) to inoculation with Bradyrhizobium japonicum and chemical fertilisation with diammonium phosphate (DAP) in a clay loam in Zaire. The selected strain of B. japonicum, IRAT FA3 was used as peat-based inoculum. No significant difference was observed between inoculation (IRAT FA3), DAP application, and the combination IRAT FA3 + DAP. These three treatments were significantly higher than the control treatment for seed yield and harvest index (HI). Inoculated plants yielded significantly higher nodulation than un-inoculated ones. Farmers may save approximately 92% of their money by inoculation rather than using chemical fertilisers with potential for soil and water pollution.
