Question

Which of the following crop is NOT a legume crop?

• A. Beans
• B. Rapeseed mustard
• C. Soybean
• D. Groundnut

Answer 1

The Correct Option is B

In the context of agricultural crops, identifying which crop is not a legume requires understanding what legumes are. Legumes are plants whose seeds are enclosed in a pod. They have a symbiotic relationship with bacteria to fix nitrogen from the atmosphere, enriching soil fertility. Common examples include beans, lentils, and peanuts (groundnut).

Let's analyze the options:

• Beans: A classic legume crop, well-known for its protein-rich seeds.
• Soybean: Another legume, extensively cultivated for oil and protein.
• Groundnut: Also known as peanut, a leguminous plant grown for oil and protein.
• Rapeseed mustard: Though an important oilseed crop, it does not belong to the legume family. It falls under the category of cruciferous vegetables.

From this analysis, the crop that is NOT a legume is Rapeseed mustard.

Answer 2

The correct answer is (B) Rapeseed-mustard.

Let's go over each option:

(A) Berseem: This is a legume crop, commonly grown as fodder. It belongs to the family Fabaceae and is used for improving soil fertility by fixing nitrogen.

(B) Rapeseed-mustard: This is NOT a legume. It is an oilseed crop belonging to the family Brassicaceae. While it provides oil, it does not have the nitrogen-fixing ability characteristic of legume crops.

(C) Soybean: This is a legume crop, belonging to the family Fabaceae. Soybeans are rich in protein and are widely used in food and oil production.

(D) Groundnut: Also known as peanut, this is a legume crop belonging to the family Fabaceae. It has the ability to fix nitrogen in the soil.

Thus, rapeseed-mustard is not a legume, and the correct answer is (B) Rapeseed-mustard.
