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

To determine which crops require a minimum quantity of NPK (Nitrogen, Phosphorus, and Potassium) or urea for their proper growth, it's important to understand the nutrient requirements of different crops. Generally, crops are classified based on their fertilization needs:

1. Cereals: Crops like rice, wheat, and maize often require significant NPK inputs because they need high nitrogen levels for vegetative growth.

2. Legumes: Crops such as beans and peas often have lower NPK requirements because they can fix nitrogen from the atmosphere through their root nodules.

3. Root Crops: Potatoes and carrots generally have moderate nutrient requirements.

4. Fruits and Vegetables: These crops vary widely, but many, like tomatoes and peppers, require sufficient nutrients for fruit development.

To answer your question accurately, you would need to compare specific crops. If options are provided, typically, legumes would require a minimum quantity of NPK or urea compared to cereals and fruiting vegetables due to their ability to fix atmospheric nitrogen.
