Agricultural Geography and Cropping Patterns

Kharif crops are sown with the onset of the south west monsoon in June and July and harvested in September and October; they are the monsoon crops and are water demanding. Rabi crops are sown in October and November on residual soil moisture or under irrigation and harvested in March and April; they are the winter crops and require a cool growing season with a warm ripening period.

• Items 1, 2 and 3, cotton, groundnut and rice, are all sown with the monsoon and are kharif crops, rice being the archetype and cotton and groundnut both being long duration monsoon crops of the black and red soil tracts.
• Item 4, wheat, is the archetypal rabi crop of the north western plains, requiring a cool sowing season, and it is the single item that does not belong. The official answer (c) follows. The elimination route is wheat alone: recognising it as rabi removes options (a) and (d) immediately, and rice, which no candidate will place in rabi, removes option (b), so the question can be answered from the two crops every candidate knows. The complication worth mentioning in class is that rice is grown in all three seasons in parts of the east and south, the boro crop being a summer rice, but the kharif classification is the one the question intends.

All three pairs are incorrectly matched, so the official answer is (d).

• Pair 1 is wrong on climate. Kinnaur is a cold, high-altitude district of Himachal Pradesh in the trans-Himalayan rain shadow, known for apples, almonds, apricots and the chilgoza pine nut. Areca nut is a humid tropical palm crop, grown in Karnataka, Kerala, Assam and the coastal belt, and cannot be grown at that altitude.
• Pair 2 is wrong on region. Mewat, now Nuh, is a semi-arid district of southern Haryana on the Aravalli fringe, characterised by low rainfall, groundwater problems and pearl millet and mustard cultivation; the mango belts of northern India are in Uttar Pradesh around Malihabad, in Bihar and in Andhra Pradesh.
• Pair 3 is wrong on both region and crop ecology. The Coromandel is the eastern coastal plain south of the Krishna delta, given to rice, groundnut and coconut; soya bean is overwhelmingly a crop of the Malwa plateau of Madhya Pradesh and of Maharashtra and Rajasthan, grown on black soils in the kharif season. The governing principle is climatic matching rather than recall of any list, since each pair puts a crop in a climate that cannot support it.

The New World means the Americas and the Old World means Eurasia and Africa. Tobacco was domesticated in the Americas, cocoa in Mesoamerica and the Amazon basin, and rubber, Hevea brasiliensis, in the Amazon, so all three in option (a) are New World domesticates carried east after 1492, which makes (a) correct.

• Option (b) fails on cotton, which has both New World and Old World domestications, the Old World species Gossypium arboreum and Gossypium herbaceum having been cultivated in the Indus valley and in Africa long before contact, so cotton cannot be presented as a New World introduction into the Old World.
• Option (c) fails twice, since coffee was domesticated in Ethiopia and Yemen and sugarcane in New Guinea and Southeast Asia, both Old World.
• Option (d) fails on coffee and on wheat, wheat being the founder crop of the Fertile Crescent. The elimination route is quick for a prepared candidate, since coffee and wheat are unambiguously Old World and remove options (c) and (d), and the residual decision between (a) and (b) rests on cotton alone.

• Statement 1 is correct. Rice occupies the largest area of any kharif crop in India, of the order of forty million hectares, and it is also the largest single crop by area in the country taken across seasons.
• Statement 2 is incorrect. Kharif oilseeds, dominated by soyabean and groundnut with sesamum, castor and sunflower alongside, occupy roughly eighteen to nineteen million hectares, whereas kharif jowar occupies only about two to three million hectares, jowar having declined steeply over decades as coarse cereals lost area to oilseeds and to rice. The comparison is not close.
• Statement 3 is correct. Cotton occupies of the order of twelve million hectares against about five million hectares for sugarcane, a ratio of well over two to one.
• Statement 4 is incorrect. Area under sugarcane has fluctuated with the price cycle and with arrears of cane payment, rising and falling, and has not steadily decreased; the word steadily is what defeats it. Since statements 1 and 3 hold, the official answer (a) follows. The practicable route is the pair of absolute claims, since coarse cereals cannot outrank oilseeds in a country that is the world's largest importer of vegetable oil, and steady decline is a strong claim that agricultural area data rarely support.

The description matches cotton on every count, giving (a). Cotton is grown in the subtropical belt, is destroyed by frost, requires a long frost free period of about two hundred and ten days for the boll to mature, and does well on the moderate rainfall of fifty to one hundred centimetres characteristic of the Deccan and Gujarat, the black regur soil retaining moisture through the dry spell.

• Option (b) is wrong because jute needs heavy rainfall of about one hundred and fifty to two hundred centimetres with high humidity and grows on the alluvium of the Ganga Brahmaputra delta.
• Option (c) is wrong because sugarcane is tropical, needs a longer growing period of ten to fifteen months and tolerates heavier soils.
• Option (d) is wrong because tea requires high rainfall and well drained sloping ground and is a plantation shrub rather than a field crop. The rainfall figure alone eliminates jute and tea, and the word subtropical eliminates sugarcane.

Water efficiency here means output obtained per unit of water consumed, so the least efficient crop is the one demanding the most water for its yield. Sugarcane is a long duration crop occupying the field for ten to eighteen months with continuously high evapotranspiration, requiring roughly 1500 to 2500 millimetres of water, which makes option (a) correct.

• Option (c) pearl millet is the opposite case, a hardy C4 dryland cereal grown in the arid Rajasthan and Gujarat belt on minimal rainfall.
• Option (d) red gram is a rainfed pulse with deep roots and low irrigation demand.
• Option (b) sunflower is moderate in requirement and is often grown as a short duration oilseed. Hence (a). The policy relevance is worth flagging in class: sugarcane's water intensity in Maharashtra and the assured price mechanism together produce one of the sharpest distortions in Indian cropping patterns.

• Statement 1 is correct. India has roughly 155 to 160 million hectares of arable land against about 120 million hectares in China, a consequence of India's much larger share of cultivable plain relative to its total area, while a large part of China is desert, plateau and mountain.
• Statement 2 is incorrect. China irrigates a higher share of its cultivated area than India does, in the region of half or more against India's figure of around 45 to 50 per cent.
• Statement 3 is incorrect. Chinese yields per hectare exceed Indian yields across most major crops, notably rice, wheat and cotton, on account of higher fertiliser and mechanisation intensity and better assured irrigation. Only statement 1 stands, giving (a).
• Options (b) and (c) require the irrigation or yield claim to hold, and (d) is ruled out by the arable area comparison.

Cote d'Ivoire and Ghana are the world's two largest cocoa producers, together accounting for roughly sixty per cent of global output. Both lie in the humid tropical belt of West Africa with high rainfall, uniform high temperature and forest soils suited to the cocoa tree.

• Option (a) is wrong because Algeria and Morocco are North African Mediterranean and desert economies where cocoa cannot grow.
• Option (b) is wrong because Botswana and Namibia are arid to semi arid southern African states dominated by the Kalahari and Namib.
• Option (d) is wrong because Madagascar and Mozambique produce cocoa only marginally, and are better known for vanilla and cashew respectively.

• Statement I is correct. India accounts for the dominant share of world turmeric production, commonly cited at around seventy to eighty per cent, and is simultaneously the largest exporter and the largest consumer, with major export destinations including Bangladesh, the UAE, the United States and Malaysia.
• Statement II is correct. More than thirty varieties of turmeric are grown across some twenty states, differing in curcumin content, duration and rhizome character, with well-known regional types including Lakadong, Alleppey Finger, Erode and Rajapuri.
• Statement III is correct. Maharashtra, Telangana, Karnataka and Tamil Nadu are among the leading producing states, along with Andhra Pradesh, Odisha and West Bengal. All three statements therefore hold, giving (d).
• Options (a), (b) and (c) each drop one accurate statement. The question sits close to a news trigger, since the National Turmeric Board was constituted in 2023 to support production, value addition and export promotion, though the content tested is standard agricultural geography rather than the Board itself.
