Zorluk: ZorSoils, Natural Vegetation, and Agriculture in India

Consider the following statements regarding soil-climatic requirements and agro-ecological conditions for major crop cultivation in India:

1. Tea bushes require friable, well-drained acidic soil with rich organic content and continuous heavy rainfall distributed evenly throughout the year without water stagnation at the roots.
2. Sugarcane cultivation in Peninsular India yields higher sucrose content and enjoys a longer crushing season compared to North India due to a tropical marine climate and absence of winter frost.
3. Cardamom and black pepper thrive primarily in well-drained lateritic or gravelly red loam soils under humid tropical conditions found along the slopes of the Western Ghats.

Which of the statements given above are correct?

  1. A
    1 and 2 only
  2. B
    2 and 3 only
  3. C
    1 and 3 only
  4. 1, 2 and 3Cevap

Cevap

All three statements (1, 2, and 3) are correct.
The correct answer identifies that all three statements are true. Tea requires acidic, well-drained soils on hill slopes to avoid root rot despite heavy rain. Sugarcane in Peninsular India benefits from a frost-free, maritime tropical climate that increases sucrose recovery and lengthens the milling season. Cardamom and black pepper depend on humid tropical conditions and well-drained lateritic red soils of the Western Ghats.

Adım Adım Çözüm

1
Analyze Statement 1 regarding tea cultivation requirements.
Tea grows best in tropical and subtropical climates with deep, fertile, acidic (pH 4.5–5.5), organic-rich, well-drained soils on hill slopes where water does not stagnate despite high rainfall (150–250 cm). Statement 1 is correct.
Water stagnation causes root rot in tea plants, making sloping topography and well-drained friable soils mandatory.
2
Analyze Statement 2 regarding sugarcane performance in Peninsular vs. Sub-Tropical India.
Peninsular India (Maharashtra, Tamil Nadu, Karnataka) features a tropical climate, higher humidity, moderate winter temperatures without frost, and fertile black/lateritic soils. This extends the crushing season and leads to higher sucrose content compared to the frost-prone sub-tropical North. Statement 2 is correct.
Frost damages sugarcane crop maturation, whereas maritime tropical influence aids continuous sucrose synthesis.
3
Analyze Statement 3 regarding spices (cardamom and black pepper) in the Western Ghats.
Commercial plantation of black pepper and cardamom is concentrated in Kerala, Karnataka, and Tamil Nadu along the Western Ghats, where humid tropical temperatures, high annual rainfall, and well-drained humus-rich lateritic or red soils coexist. Statement 3 is correct.
These spice crops demand heavy moisture accompanied by good soil drainage to prevent root diseases.
