Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that seeds that do not _______ when dropped in water are not fit for sowing in fields. We need to identify the action that determines whether seeds are suitable for sowing.

2. **Identifying Seed Types**: There are two types of seeds based on their behavior in water:
- **Floating Seeds**: These seeds do not sink when placed in water. They are typically hollow and may be in a diseased condition. Their density is low, which causes them to float.
- **Sinking Seeds**: These seeds sink when placed in water. They are generally heavier, not diseased, and have a high density.

3. **Determining Fit for Sowing**: From the information above, we can conclude that:
- Seeds that float (do not sink) are not fit for sowing.
- Seeds that sink are fit for sowing.

4. **Filling in the Blank**: Based on the conclusion, we can fill in the blank in the question. The correct answer is "sink". Thus, the complete statement reads: "Seeds that do not sink when dropped in water are not fit for sowing in fields."

5. **Final Answer**: The answer to the question is "sink".
