The correct Answer is
A-1, B-3, C-2, D-4
Explanation
This question assesses knowledge of the specific agro-climatic conditions required for the cultivation of various millet and cereal crops in India. Understanding the ideal temperature, soil types, and moisture requirements for each crop is crucial for agricultural geography.
Statement-wise Analysis
- A. Jowar (Sorghum) - 1. Rain-fed crop mostly grown in moist areas
- Correct. Jowar is primarily a rain-fed crop, thriving in areas that receive adequate rainfall, particularly in moist regions of the Deccan Plateau. It is a staple food crop in semi-arid regions.
- B. Bajra (Pearl Millet) - 3. Grows well on sandy soils and shallow black soil
- Correct. Bajra is known for its drought tolerance and ability to grow in poor, sandy soils and shallow black soils, making it suitable for dry and arid regions like Rajasthan.
- C. Ragi (Finger Millet) - 2. Grows well on red, black, sandy, loamy and laterite soils
- Correct. Ragi is a hardy crop that can be grown on a wide variety of soils, including red, black, sandy, loamy, and laterite soils, demonstrating its adaptability to diverse soil conditions.
- D. Maize (Corn) - 4. Requires temperature between 21°C to 27°C and grows well in old alluvial soil
- Correct. Maize is a kharif crop that requires a temperature range of 21°C to 27°C and grows well in old alluvial soils (Bhangar). It is also grown in some states during the rabi season.
Key Takeaway
Different millet and cereal crops have distinct requirements for temperature, rainfall, and soil types, which determine their geographical distribution and suitability for cultivation.
