Answer

To solve the question "Complete manure is that which supplies," we need to identify what constitutes complete manure in terms of nutrient content.

### Step-by-Step Solution:

1. **Understanding Manure**:
- Manure is defined as organic matter that is used as fertilizer in agriculture. It enriches the soil and provides essential nutrients for plant growth.

2. **Identifying Complete Manure**:
- Complete manure is characterized by its ability to supply all essential nutrients required for plant growth. The key nutrients that plants need are nitrogen (N), phosphorus (P), and potassium (K).

3. **Role of Nutrients**:
- **Nitrogen (N)**: Crucial for leaf growth and overall plant vigor. It helps in the formation of chlorophyll, which is essential for photosynthesis.
- **Phosphorus (P)**: Important for root development, flower, and fruit production. It plays a significant role in energy transfer within the plant.
- **Potassium (K)**: Vital for overall plant health, it helps in the regulation of various physiological processes, including water uptake and enzyme activation.

4. **Conclusion**:
- A complete manure must provide nitrogen, phosphorus, and potassium to be considered effective for plant nourishment. Therefore, the correct answer to the question is that complete manure supplies N, P, and K.

### Final Answer:
Complete manure is that which supplies Nitrogen (N), Phosphorus (P), and Potassium (K).
