Which of the following crop is NOT a legume crop?
- Beans
- Rapeseed mustard
- Soybean
- Groundnut
The Correct Option is B
Approach Solution - 1
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.
Approach Solution -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.
