    What happened when we inoculated Rhizobium in heat field ?

    A)  No increase in production (nitrogen content of soil remains same)

    B)  A lot of increase in production (nitrogen content of soil increases)

    C)  Fertility of soil decreases

    D)  Fertility of soil increases

    Correct Answer: A

    Solution :

    Rhizobium species is symbiotic nitrogen-fixing bacteria, which occurs in root nodules of legumes. When we inoculated Rhizobium in wheat field, there is no increase in production. Because wheat has no root nodules for fixing nitrogen content. Therefore, nitrogen content of soil will remain same.
