Match List-I (Crop / Vegetation Types in India) with List-II (Specific Pedo-Climatic and Topographic Requirements) and identify the correct associations.

Tea (Camellia sinensis)Deep, acidic, humus-rich soil on gentle hill slopes receiving $150\text{ cm} - 250\text{ cm}$ annual rainfall without waterlogging
Cotton (Gossypium spp.)Clayey Vertisols (Black Soil) with high moisture retention, requiring at least $210$ frost-free days and bright sunshine during boll opening
Natural Rubber (Hevea brasiliensis)Hot and humid equatorial/tropical climate with rainfall $>200\text{ cm}$ , temperatures consistently above $25^\circ\text{C}$ , and well-drained lateritic soils
Jute (Corchorus capsularis)Annually renewed alluvial floodplain silt (Khadar), high humidity, and temperatures ranging between $24^\circ\text{C} - 35^\circ\text{C}$ during growth

Answer

Tea pairs with deep acidic well-drained hill slope soil; Cotton pairs with moisture-retaining Vertisols requiring 210 frost-free days; Natural Rubber pairs with hot-humid equatorial climate and lateritic soils; Jute pairs with annually renewed floodplain silt (Khadar).

Each crop is accurately paired with its definitive pedological, thermal, and moisture thresholds: Tea with acidic hill-slope soils, Cotton with Vertisols and 210 frost-free days, Rubber with equatorial high-rainfall lateritic soils, and Jute with deltaic Khadar silt.

Step-by-Step Solution

Analyze the pedological and drainage requirements for plantation crops (Tea and Rubber)

Tea requires acidic soils on gentle hill slopes to avoid root rot from stagnant water (

150-250\text{ cm}

rainfall). Rubber requires hot-humid equatorial conditions (

>200\text{ cm}

rainfall) on well-drained lateritic slopes.

Topography and soil acidity are critical factors differentiating tea plantations from other equatorial tree crops.

Evaluate climatic and soil conditions for cash fiber crops (Cotton and Jute)

Cotton needs clayey black Vertisols, moderate rainfall,

210

frost-free days, and sunny harvest periods. Jute requires heavy rainfall and annually replenished riverine silt (Khadar) in deltaic plains.

Soil texture (Vertisols vs Khadar silt) and sunshine/frost duration dictate the spatial distribution of cotton vs jute.

Verify all four matching pairs against standard agro-climatic zones of India

Tea matches gentle acidic hill slopes; Cotton matches Vertisols with 210 frost-free days; Rubber matches hot-humid lateritic belts; Jute matches renewed floodplain Khadar silt.

Ensures full pedagogical consistency across all soil and climate parameters.
