CBSE Class 10 Social Science Agriculture MCQs Set 06

Answer: (c) Wheat requires 50 to 75 cm of annual rainfall, and rice requires more than 100 cm

Explanation:
1. Wheat needs relatively low rainfall (50-75 cm), while rice needs heavy rainfall (over 100 cm) — this is an accurate distinction between the two crops.

Teacher's Note:
a) Wheat needs 50-75 cm rainfall; rice needs over 100 cm.
b) The other options reverse facts: wheat is actually Rabi, not Kharif, and India leads the world in rice production, not just second in wheat.

Answer: (d) Commercial farming

Explanation:
1. Commercial farming relies heavily on modern inputs like HYV seeds, fertilisers and pesticides to maximise yield for sale.

Teacher's Note:
a) Commercial farming uses heavy modern inputs for market-oriented production.
b) This differs from primitive/subsistence farming, which relies on traditional methods.

Answer: (b) Traditional methods based

Explanation:
1. Primitive farming relies on traditional tools and methods, unlike intensive subsistence farming, which uses labour and machines together.

Teacher's Note:
a) Primitive farming is traditional-methods based, using simple tools.
b) Intensive subsistence farming instead blends heavy labour with some machine use.

Answer: (b) Pulses require intensive and excessive irrigation facilities

Explanation:
1. Pulses actually require little irrigation and can grow on moisture stored in the soil, making the claim that they need 'intensive and excessive irrigation' false.

Teacher's Note:
a) Pulses need very little irrigation, not excessive irrigation.
b) This is why they're often grown on residual soil moisture, in rotation with other crops.

Answer: (d) It grows in black soil in the Deccan traps

Explanation:
1. Tea actually requires deep, fertile, well-drained soil rich in humus, not the black soil of the Deccan traps (which is associated with cotton cultivation instead), making this statement the odd one out.

Teacher's Note:
a) Tea needs deep, humus-rich, well-drained soil, not black (Deccan trap) soil.
b) Black soil is instead associated with cotton cultivation.

Answer: (b) Both (A) and (R) are true but (R) is not the correct explanation of (A)

Explanation:
1. Agriculture is indeed age-old, and cultivation methods have indeed changed significantly — but the change in methods doesn't explain why agriculture is age-old; the two facts are both true but unconnected as cause and explanation.

Teacher's Note:
a) Both statements are factually true, but they describe separate facts, not cause-and-effect.
b) Agriculture's age doesn't depend on whether methods changed over time.

Answer: (b) Statements (I), (II) and (III) are appropriate

Explanation:
1. Statements I, II and III correctly describe commercial farming's varying intensity and crop role across regions; statement IV ('slash and burn') instead describes primitive subsistence farming, not commercial farming.

Teacher's Note:
a) I, II and III correctly describe commercial farming's variable, place-dependent nature.
b) 'Slash and burn' (IV) describes primitive subsistence farming, not commercial farming.

Answer: (c) Millets

Explanation:
1. Jowar, bajra and ragi are classified as millets, a subgroup of cereals alongside rice and wheat.

Teacher's Note:
a) Jowar, bajra and ragi fall under the category of millets.
b) Millets are one of the main types of cereal crops in India.

Answer: (a) (I), (IV), (III) and (II)

Explanation:
1. India attained Independence in 1947 (I); the Green Revolution began in the 1960s (IV); the White Revolution followed afterward (III); and the comprehensive land development programme came after these reforms (II).

Teacher's Note:
a) Correct order: Independence (1947) → Green Revolution (1960s) → White Revolution → land development programme.
b) This traces India's post-independence agricultural reform timeline.

Answer: (b) Maize

Explanation:
1. Maize fits all these clues: it is used as both food and fodder, is a Kharif crop in this temperature range, and has benefited from modern agricultural inputs.

Teacher's Note:
a) Maize is used as both food and fodder, grown in Kharif season.
b) It has seen rising production thanks to modern agricultural inputs.

Answer: (c) Organic fertilisers could be added to the soil to regain fertility rather than abandoning it

Explanation:
1. Adding organic fertiliser to restore soil fertility is a genuine alternative to burning crop residue, directly reducing the pollution it causes.

Teacher's Note:
a) Organic fertiliser can restore soil fertility without needing to burn crop residue.
b) This directly reduces the air pollution caused by stubble burning.

Answer: (c) (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Explanation:
1. Guava is significantly grown in Uttar Pradesh (III); oranges in Maharashtra's Nagpur region (IV); apples in Jammu and Kashmir (I); and bananas in Kerala (II).

Teacher's Note:
a) Guava = UP; Orange = Nagpur, Maharashtra.
b) Apple = Jammu & Kashmir; Banana = Kerala.

Answer: (c) Clue (I) and (II)

Explanation:
1. Groundnut is specifically a Kharif crop that accounts for about half of India's major oilseed production, making Clues (I) and (II) the most reliably identifying details; Haryana is not actually the largest groundnut producer (Gujarat is).

Teacher's Note:
a) Groundnut is a Kharif crop providing about half of India's major oilseed output.
b) Haryana is NOT the largest groundnut producer, so that clue is misleading.

Answer: (c) Increasing export duties on agricultural products

Explanation:
1. Increasing export duties would discourage agricultural exports and trade, rather than helping modernise agriculture, unlike the other three genuinely supportive measures.

Teacher's Note:
a) Higher export duties would hurt, not help, agricultural modernisation.
b) Infrastructure, education and weather research all genuinely support modernisation.
