- Name India's most extensive soil type by area, and the two sub-types it is divided into. — Alluvial soil, covering roughly 40% of India's area; divided into Bhangar (older, terrace-level) and Khadar (newer, floodplain) alluvium.
- Which soil type is famously "self-ploughing," and why? — Black/regur soil — it swells and cracks deeply on drying-and-wetting cycles due to its high clay content, aerating the subsoil naturally.
- What does the word "laterite" literally mean, and why? — From Latin "later," meaning brick — laterite soil hardens irreversibly on repeated wetting-drying cycles and has historically been cut and used as building brick.
- Which soil type is largely man-made, arising from excess canal irrigation without drainage? — Saline/Alkaline soil (usar/reh/kallar), caused by waterlogging and capillary salt rise.
- Which Kerala region is famous for peaty, below-sea-level rice cultivation? — Kuttanad.
- What do the words "Kharif" and "Rabi" literally mean, and which season does each refer to? — Kharif means "autumn" (monsoon-sown, autumn-harvested crop); Rabi means "spring" (winter-sown, spring-harvested crop).
- Name West Bengal's three rice crops in sowing-to-harvest order. — Aus, Aman, Boro.
- Which two Kharif crops are Tamil Nadu's regionally renamed rice crops tied to the northeast monsoon? — Kuruvai and Samba (also Thaladi and Navarai).
- Which state is currently India's largest rice producer (approx., recent years), and which state has the highest rice yield per hectare? — West Bengal largest producer (approx.); Punjab highest yield per hectare due to near-total irrigation.
- Name India's basmati rice belt, and what special trade designation it carries. — Punjab, Haryana, and western Uttar Pradesh; it carries a Geographical Indication (GI) tag.
- Which state is India's largest wheat producer, and which two states have the highest wheat yields? — Uttar Pradesh largest producer; Punjab and Haryana highest yields.
- Which two coarse cereals are the classic drought-tolerant crops of India's semi-arid tracts, and which is grown in both Kharif and Rabi seasons? — Jowar and Bajra; Jowar is grown in both seasons in parts of the Deccan.
- Which single state dominates India's gram (chickpea) output? — Madhya Pradesh.
- Name India's top two sugarcane-producing states (approx.), and which has the higher sugar recovery/output efficiency. — Uttar Pradesh (largest by cane tonnage) and Maharashtra (higher sugar recovery/efficiency).
- Which soil type best suits cotton, and why? — Black/regur soil — its high moisture retention lets cotton survive dry spells during its long growing and sunshine-dependent picking period.
- Which state overwhelmingly dominates India's jute production, and why is that region uniquely suited to it? — West Bengal — the Ganga-Brahmaputra delta provides fresh, flood-renewed alluvial soil plus the high rainfall and humidity jute requires.
- Which tea-growing region holds India's first-ever Geographical Indication tag, and in what year was it registered? — Darjeeling tea, registered 2004.
- Which state dominates Indian coffee production, and which two districts within it are most associated with it? — Karnataka; Kodagu (Coorg) and Chikmagalur.
- Which state overwhelmingly dominates natural rubber production, and what soil/climate condition makes it so narrowly concentrated? — Kerala; rubber needs a hot, consistently humid equatorial-type climate with no pronounced dry season, found in India almost only in Kerala.
- Name India's four major oilseeds covered in this book and one leading state for each. — Groundnut (Gujarat), Mustard/Rapeseed (Rajasthan), Soybean (Madhya Pradesh), Sunflower (Karnataka, historically).
- Which spice originally drew European trading powers to India's Malabar coast from the 15th century onward? — Black pepper.
- Name the three core inputs of the Green Revolution. — High-Yielding Variety (HYV) seeds, assured irrigation, and heavy chemical fertiliser/pesticide input.
- Which two individuals are most associated with the Green Revolution's HYV seed technology, one international and one Indian? — Norman Borlaug (international, Mexico-based wheat breeding) and M.S. Swaminathan (India, adaptation and championing domestically).
- Name three commonly cited criticisms of the Green Revolution. — Groundwater depletion, soil degradation/salinity, regional inequality, and loss of crop diversity (pulses/millets displaced) — any three.
- Name the four major irrigation systems of India and one state/region each is most associated with. — Canal (Punjab/Haryana), Well/tube-well (UP/Rajasthan), Tank (Tamil Nadu/Andhra Pradesh), Drip/sprinkler micro-irrigation (Maharashtra/AP).
- Which irrigation system is India's traditional Deccan-plateau method, and why does the hard-rock terrain suit it? — Tank irrigation — hard, impermeable crystalline rock makes canal-building and groundwater access difficult, so surface runoff is instead captured and stored in tanks.
- Name the river, and the states benefited, for the Bhakra-Nangal project. — Sutlej river; Punjab, Haryana, Rajasthan.
- Which river valley project is explicitly modelled on the American Tennessee Valley Authority, and what was it originally built to control? — Damodar Valley Corporation (1948); built primarily to control the Damodar's historic flooding ("river of sorrow" in Bengal).
- Which dam and canal system converted parts of the Thar desert into productive cropland, and from which two rivers does it draw water? — The Indira Gandhi Canal (Rajasthan Canal), drawing from the Sutlej-Beas system via the Harike Barrage.
- Name the five Agriculture Census landholding categories in order of size, and state which two categories together account for the large majority of India's operational holdings. — Marginal (below 1 ha), Small (1–2 ha), Semi-medium (2–4 ha), Medium (4–10 ha), Large (10+ ha); Marginal and Small holdings together account for the large majority.
- Which Soil Taxonomy order corresponds to India's black/regur soil, and which corresponds to the young alluvium of the Indo-Gangetic plain? — Vertisols (black/regur soil); Inceptisols (young Indo-Gangetic alluvium, the largest single Soil Taxonomy order by area).
- Name the three main mechanisms of soil erosion in India and one region associated with each. — Water erosion (Chambal ravines/gully erosion), wind erosion (Thar desert), and shifting/jhum cultivation (Northeastern hill states).
- Which mid-January festival cluster marks the Rabi/winter harvest across different regions of India, and name at least two festivals in it. — Makar Sankranti, Lohri, Pongal, and Bihu — any two — all celebrated within days of each other in mid-January.
- Which state is India's largest producer of potatoes, and which crop's cool-season, alluvial-soil profile does potato cultivation most resemble? — Uttar Pradesh; it resembles wheat's Rabi, cool-season, alluvial-soil profile.
- What is the ideal N:P:K fertiliser ratio recommended by agronomists, and why does actual consumption in the Green Revolution belt skew away from it? — Roughly 4:2:1; actual consumption skews nitrogen-heavy because urea (nitrogenous fertiliser) is priced much lower than phosphatic and potassic fertilisers under the subsidy structure.
- Name the two phases of India's Green Revolution and the crop each phase was primarily built around. — Phase I (mid-1960s–late 1970s, wheat) and Phase II (1980s onward, extended to rice and a wider set of states).
- What do the "White Revolution" and "Blue Revolution" refer to, and which scheme/leader is associated with each? — White Revolution — Operation Flood, milk/dairy cooperatives, led by Dr. Verghese Kurien. Blue Revolution — fisheries and aquaculture promotion, formalised under the Pradhan Mantri Matsya Sampada Yojana.
- Name PMKSY's four components. — Accelerated Irrigation Benefit Programme (AIBP), Har Khet Ko Pani, Per Drop More Crop, and Watershed Development.
- Which river-interlinking project became the first to receive formal Cabinet approval and begin construction? — The Ken-Betwa Link, connecting the Ken river (Madhya Pradesh) to the water-deficit Betwa basin.
- Why is the Periyar Dam considered unusual among Indian irrigation projects? — Though built on the Periyar river in Kerala, it diverts water eastward through a tunnel to irrigate Tamil Nadu's Vaigai basin — the state hosting the dam is not its primary irrigation beneficiary.
