Which of the following crops would require a minimum quantity of NPK or urea for their proper growth?

Options

A. Paddy
B. Peas
C. Wheat
D. ground nut

Answer

To determine which crop requires a minimum quantity of NPK (Nitrogen, Phosphorus, and Potassium) or urea for proper growth, we need to consider the nutrient requirements of various crops. Here’s a step-by-step solution:

### Step 1: Understand NPK and Urea
- NPK fertilizers contain three essential nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K).
- Urea is a nitrogen-rich fertilizer that provides nitrogen to plants.

### Step 2: Identify Crop Nutrient Requirements
- Different crops have varying nutrient requirements based on their growth stages and types.
- Some crops are more efficient in utilizing soil nutrients and may require less fertilizer.

### Step 3: Consider Examples of Crops
- Common crops include cereals (like rice and wheat), legumes (like peas and beans), and root vegetables (like potatoes and carrots).
- Legumes, for instance, have a unique ability to fix atmospheric nitrogen through symbiotic relationships with bacteria, reducing their need for additional nitrogen fertilizers.

### Step 4: Analyze the Options
- If the question provides specific crops, compare their nutrient requirements.
- Generally, legumes (like peas, beans, and lentils) would require less NPK or urea compared to cereals and other high-nutrient-demanding crops.

### Step 5: Conclusion
- Based on the analysis, the crop that would require a minimum quantity of NPK or urea for proper growth is likely a legume or similar crop that has lower nutrient needs.

### Final Answer
- The crop that would require a minimum quantity of NPK or urea for its proper growth is a legume (e.g., peas or beans).
