Indian Agriculture — Cropping Pattern, Irrigation & Productivity

NABARD's Agriculture & Rural Development paper expects a scheme named with its year and a figure cited with its source — general familiarity with "Indian agriculture" is not enough. This chapter opens the ARD subject with the crop calendar, irrigation structure, and productivity questions that anchor nearly every later ARD topic.

1. The three cropping seasons

Indian agriculture runs on three distinct cropping seasons, each defined by the monsoon and temperature cycle rather than the calendar year alone.

Kharif is sown with the onset of the south-west monsoon, roughly June-July, harvested around September-October — rice, cotton, maize, soybean, groundnut are typical kharif crops.

Rabi is sown after the monsoon retreats, roughly October-November, harvested around March-April, relying on residual soil moisture and irrigation — wheat, mustard, gram, barley are typical rabi crops. Zaid is a short summer season between rabi harvest and kharif sowing, roughly March-June, entirely irrigation-dependent since it falls outside the monsoon — watermelon, cucumber, and fodder crops are typical zaid crops.

A crop's seasonal classification is not arbitrary — it follows directly from that crop's water and temperature requirements, which is why rice (a water-intensive crop) is predominantly kharif in most of India, while wheat (requiring cooler growing conditions and less water at critical stages) is predominantly rabi — a mechanism-based understanding that answers questions testing "why" a crop falls in a given season, not just "which" season it falls in.

2. Irrigation — sources, coverage, and the shift toward micro-irrigation

India's irrigation sources split into canals (surface water diverted from rivers/reservoirs), tanks (stored surface water, historically dominant in southern India), tube wells and other wells (groundwater extraction), and a smaller but rapidly growing micro-irrigation share (drip and sprinkler systems).

Groundwater (tube wells and wells combined) is now the single largest source of irrigation in India by area covered — a structurally important fact, since groundwater over-extraction (drawing water faster than natural recharge replaces it) is the specific mechanism behind falling water tables in intensively-irrigated regions, distinct from a general "water scarcity" framing.

The Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), launched in 2015, is the flagship scheme unifying India's irrigation-expansion efforts, with "Per Drop More Crop" as its micro-irrigation-focused component — this component specifically targets water-use efficiency (getting more output per unit of water applied) rather than simply expanding the area under irrigation, since drip/sprinkler systems can extend a given water source's coverage substantially compared to flood irrigation.

3. Productivity — closing the yield gap

Indian agricultural productivity (yield per hectare) for most major crops remains below the global average and well below the yields achieved by leading producer countries for the same crop — and closing this "yield gap" through better inputs, technology and practices, rather than only expanding cultivated area, is the central productivity-policy question in Indian agriculture today.

The factors most commonly cited behind the yield gap are fragmented landholdings (limiting mechanisation and scale economies), uneven and often untimely input access (certified seeds, balanced fertiliser use, credit for inputs), and irrigation dependence in a country where a large share of net sown area still relies on the monsoon rather than assured irrigation — a single poor monsoon year can still meaningfully depress national foodgrain output specifically because of this residual rain-dependence.

The Green Revolution (from the mid-1960s) is the historical reference point for India's earlier major productivity leap — high-yielding variety (HYV) seeds, chemical fertilisers, and expanded irrigation concentrated initially in wheat and in specific states (Punjab, Haryana, western Uttar Pradesh) — and its well-known limitation, regionally concentrated and crop-concentrated gains (rice and wheat far more than pulses and oilseeds), is precisely why closing today's yield gap for pulses/oilseeds and extending gains to rain-fed regions remains a distinct, still-unresolved policy priority.

Worked Examples

Example 1. Classify each crop by its typical cropping season: (a) wheat, (b) rice, (c) watermelon.

(a) Rabi. (b) Kharif. (c) Zaid.

Example 2. Why is rice predominantly a kharif crop in India?

Because rice is water-intensive, and the kharif season coincides with the south-west monsoon, providing the water availability rice cultivation requires — the seasonal classification follows directly from the crop's water requirement.

Example 3. What is the single largest source of irrigation in India by area covered?

Groundwater (tube wells and wells combined).

Example 4. What specific problem does groundwater over-extraction cause, and how does it differ from a general "water scarcity" framing?

Falling water tables in intensively-irrigated regions, caused specifically by drawing groundwater faster than natural recharge can replace it — this is a distinct, mechanism-specific problem from a general claim that "India has water scarcity."

Example 5. What is "Per Drop More Crop," and which broader scheme is it a component of?

A micro-irrigation-focused component targeting water-use efficiency (drip/sprinkler systems), under the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), launched in 2015.

Example 6. Name two factors most commonly cited behind India's agricultural yield gap.

Any two of: fragmented landholdings limiting mechanisation/scale, uneven or untimely input access (seeds, fertiliser, credit), and continued rain-dependence in unirrigated tracts.

Example 7. What was the Green Revolution's well-known limitation, despite its productivity gains?

Its gains were regionally concentrated (Punjab, Haryana, western UP) and crop-concentrated (wheat and rice far more than pulses and oilseeds), leaving rain-fed regions and non-cereal crops with comparatively limited benefit.

Summary

India's three cropping seasons — Kharif, Rabi, Zaid — are defined by the monsoon and temperature cycle, and a crop's seasonal classification follows directly from its water/temperature requirements rather than being an arbitrary calendar assignment.

Groundwater is now India's largest irrigation source by area, making groundwater-table depletion (from extraction outpacing recharge) a specific, mechanism-based concern rather than generic "water scarcity" — and PMKSY (2015), particularly its "Per Drop More Crop" micro-irrigation component, is the flagship scheme addressing water-use efficiency rather than only irrigated-area expansion.

Closing India's yield gap — driven by fragmented holdings, uneven input access, and residual rain-dependence — rather than only expanding cultivated area, is the central productivity-policy question today, building on but also correcting for the Green Revolution's regionally- and crop-concentrated legacy.
