Which of the following crops is categorized as a leguminous crop, often used for nitrogen fixation in soil?
Wheat
Rice
Soybean
Maize
Soybean
Soybean is a leguminous crop that houses symbiotic bacteria called Rhizobium in its root nodules, which convert atmospheric nitrogen into ammonia to fertilize the soil. This process, known as biological nitrogen fixation, enhances soil fertility and reduces the dependency on chemical fertilizers.
Soybean is a leguminous crop that houses symbiotic bacteria called Rhizobium in its root nodules, which convert atmospheric nitrogen into ammonia to fertilize the soil. This process, known as biological nitrogen fixation, enhances soil fertility and reduces the dependency on chemical fertilizers.
Nitrogen fixation in plants is governed by the biological process of the nitrogen cycle, which is a fundamental concept in Geography/Ecology under the Earth's nutrient distribution systems.
Soybean is a Kharif crop that belongs to the family Fabaceae.
Rhizobium bacteria perform a symbiotic relationship with legumes to fix atmospheric nitrogen.
Crop rotation with leguminous crops is a common practice to restore soil nitrogen levels naturally.
Soybean is often referred to as 'yellow gold' or 'miracle bean' due to its high protein and oil content.
Wheat and Maize are classified as cereals and belong to the Poaceae family, which do not fix nitrogen.
Rice is a semi-aquatic cereal crop that requires large amounts of water and does not possess nitrogen-fixing root nodules.
Option A (Wheat) and Option B (Rice) are staple cereal crops, not legumes.
C is correct тАФ Soybean is a leguminous crop that enhances soil nitrogen levels through its symbiotic relationship with nitrogen-fixing bacteria.
When studying agricultural geography, remember that leguminous crops like soybean, pulses, and groundnut are vital for sustainable farming, frequently tested alongside soil types and crop seasons (Kharif/Rabi).
