Abstract

Rhizobium inoculum application in planting furrows by mixing with either farm soil (FS) or Farm Yard Manure (FFYM) significantly increased the number and dry weight of nodules in blackgram (Vigna mungo L.) compared to the seed treatment (ST) method. Inoculation with both FS and FFYM methods also favoured the plant dry matter, N accumulation and grain and straw yield slightly. The recommended inoculum rate (20 g/kg seed) recorded significantly more number and dry weight of nodules over the uninoculated control. A 2.5 fold increase in the recommended inoculum rate further increased the nodulation and registered significantly more number and dry weight of nodules over 20 g inoculum/kg seed at 45 days with all the methods. The two inoculum rates did not differ significantly among themselves in other studied parameters, nevertheless, 50 g inoculum/kg seed produced 11.9 to 13.0 per cent more grain yield over 20 g inoculum/kg seed rate with the different methods. PSB alone was statistically comparable to the uninoculated control, but along with Rhizobium at both rates, it gave slightly more nodulation, plant dry matter and yields than with Rhizobium alone
