Question

Farmers coat the seeds of cereals with rhizobial solution. Why is this done?

• A. Rhizobium kills harmful microbes.
• B. Rhizobium helps in seed germination.
• C. Rhizobium provides oxygen to the seeds.
• D. Rhizobium provides nitrogen to the plantlets.

Answer 1

The correct option is D Rhizobium provides nitrogen to the plantlets.

Coating seeds of plants other than legumes with rhizobial solution or powder is called rhizobial innoculation. Once the seeds germinate, the Rhizobium enters the plantlets and provides nitrogen to them.
