Solution

Microorganisms are the most essential resource for a farmer because they nourish the soil with essential nutrients.

Role of microorganisms in crop production are:

1. Soil contains numerous minerals in forms that plants cannot absorb directly.

2. Microbes like fungi and bacteria with the help of their enzymatic machinery break down these minerals into forms that can be absorbed by crops.

3. Soil microbes play a vital role in enhancing soil fertility, soil profile, and soil health.

4. The plant growth-promoting microbes improve plant growth and yields of crops under normal and stress conditions.

Bacillus thuringiensis (Bt) is a gram-positive bacterium that is characterized by producing parasporal crystal proteins with insecticidal activity.

Pseudomonas protegens are widespread Gram-negative, plant-protecting bacteria, and herbicides.
