Rhizobium is a bacteria found in soybean roots which increases the crop yield by atmospheric nitrogen fixing. But currently the amount of undesirable elements in the soil has so much increased that the bacteria of Rhizobium in the soybean crop are unable to function to the best of their ability.
Therefore, using Rhizobium culture produces fast legume in the roots of soybean crop and increases the yield of soybean by 50-60%.
The use of Rhizobium culture increases about 12-16 kg of nitrogen to the soil per acre.
Rhizobium culture is done by adding 5 grams per kg of seed for seed treatment and 1 kg of culture per 50 kg FYM before sowing for soil treatment.
Nitrogen deposited by Rhizobium bacteria present in the roots of the pulses is used in the next crop, which also requires less fertilization in the next crop.
