A major cash crop in India requires high temperatures ranging between 24^\circ\text{C} and… — State PSC Exam

A major cash crop in India requires high temperatures ranging between $24^\circ\text{C}$ and $35^\circ\text{C}$ , relative humidity around $80\%$ - $90\%$ , annual rainfall exceeding $150\text{ cm}$ , and fertile, well-drained silt loam alluvial soils that receive annual nutrient replenishment from river floods. Which of the following commercial crops best matches these specific agro-climatic conditions?

JuteCevap
B
Cotton
C
Tea
D
Wheat

Cevap

Jute is the correct commercial crop matching all specified climatic and soil requirements.

Jute is a major commercial fiber crop requiring a warm and humid climate (

24^\circ\text{C}\text{--}35^\circ\text{C}

>80\%

humidity) and abundant rainfall (

>150\text{ cm}

). It grows best on light sandy to clayey silt loam soils of river deltas and floodplains that receive annual silt deposits during monsoon floods.

Adım Adım Çözüm

Analyze the temperature and humidity requirements given in the prompt.

High temperatures (

24^\circ\text{C}

35^\circ\text{C}

) and high humidity (

80\%

90\%

) indicate a humid tropical cash crop.

Eliminates temperate Rabi crops like Wheat.

Evaluate the soil and moisture conditions.

The requirement of rich alluvial silt refreshed annually by inundations points directly to deltaic floodplains (such as the Lower Ganga-Brahmaputra plain).

Differentiates crops grown on basaltic black soils (Cotton) or acidic hill slopes (Tea) from floodplain cash crops.

Synthesize conditions to identify the crop.

Jute (known as the 'Golden Fibre') is predominantly cultivated in West Bengal, Assam, and Bihar under these exact floodplain and climatic parameters.

Confirms Jute as the unique correct answer.
