Agriculture

1. Agricultural foundations and environmental setting

The Indus Civilization occupied varied environments, including the Indus floodplain, Punjab, the Ghaggar-Hakra region, Balochistan and parts of Gujarat. Differences in rainfall, river behaviour, soils and groundwater encouraged locally adapted farming rather than a single agricultural system. Although Mohenjo-daro and Harappa dominate popular accounts, numerous rural settlements supplied food and maintained relationships with pastoralists, craft producers and towns.

The agricultural background extends to Mehrgarh near the Bolan Pass in Balochistan. From approximately 7000 BCE, its inhabitants cultivated cereals and kept domestic animals. Mehrgarh should be treated as evidence for early food production in the broader north-western subcontinent, not as a Mature Harappan city. Over subsequent millennia, farming settlements expanded and regional traditions developed before large-scale urban integration.

Seasonal inundation could deposit fertile silt and recharge soil moisture. Cultivators could sow after floodwaters receded, while rain-fed farming and access to groundwater offered additional possibilities. River channels also shifted and floods could destroy fields or settlements. Consequently, the same river systems that supported agriculture exposed communities to uncertainty and encouraged flexible settlement and subsistence strategies.

• Agricultural surplus helped support non-farming specialists, but the mechanisms through which surplus was collected remain uncertain.
• Modern crop calendars provide useful analogies, not direct proof of identical Harappan sowing and harvesting schedules.

2. Crops, seasons and regional diversity

Wheat and barley are repeatedly identified in Harappan archaeobotanical assemblages and were especially important in the north-west. Their generally cool-season growth requirements are consistent with winter cultivation using residual flood moisture, winter rainfall or supplementary watering. Pulses, including peas and lentils at some sites, diversified diets. Sesame and other oil-bearing crops added further variety. Crop lists must nevertheless be read site by site: a plant identified at one settlement need not have been cultivated throughout the civilization.

Evidence from Gujarat and eastern parts of the Harappan sphere indicates greater use of summer crops, including small millets and pulses. Research on settlements in the eastern Indus region has also strengthened the case for mixed seasonal cropping. Winter and summer crops could spread labour requirements and reduce dependence on a single rainfall season. However, the presence of crops from both seasons at a settlement does not prove that every farmer double-cropped the same plot.

Cotton is particularly important for examinations. Cotton textile remains from Mohenjo-daro provide direct evidence of its use, linking agriculture with spinning, weaving and exchange. Rice requires greater caution. Rice remains have been reported from sites such as Lothal and Rangpur, but their dating, identification and implications for local cultivation require careful assessment. Claims that rice was absent everywhere, or that irrigated paddy dominated Harappan agriculture, are both misleading.

• Distinguish crop presence, local cultivation and dietary importance: these are three different conclusions.
• Avoid treating every millet species as equally well attested; identifications and dates vary across sites and studies.
• Cotton illustrates how farming supplied industrial raw material as well as food.

3. Ploughing, tools and water management

Kalibangan, situated beside the now-dry Ghaggar channel in Rajasthan, provides the best-known field evidence. Excavators identified two sets of furrows crossing approximately at right angles, with different spacing between them. The field is associated with the Early Harappan settlement. It has been interpreted as evidence for cultivating two crops in differently spaced rows, sometimes compared with present-day mustard and gram cultivation. The furrows are archaeological observations; identification of the exact ancient crop combination is an inference.

Terracotta plough models from sites including Banawali support the use of plough-based cultivation. Wooden implements seldom survive, so the scarcity of actual ploughs is not proof that they were absent. Cattle, especially bullocks, probably supplied traction, while harvesting and processing could involve stone blades, other cutting implements, querns and grinding stones. There is no basis for assigning iron ploughshares to Mature Harappan farming.

Water management combined environmental opportunity with local engineering. Floodwater use and rain-fed cultivation were probably important, while wells may have provided supplementary water in some contexts. However, many known urban wells served domestic needs. Dholavira's reservoirs demonstrate sophisticated water harvesting and storage, but they do not independently establish extensive field irrigation. Large canal systems comparable to those documented in Mesopotamia have not been securely demonstrated across the Harappan heartland.

• Ploughed-field evidence: Kalibangan; terracotta plough-model evidence: Banawali.
• Do not equate urban drainage with agricultural irrigation.
• Distinguish plausible local channels or flood-control measures from a proven civilization-wide canal network.

4. Livestock, storage and the urban economy

Cultivation operated alongside animal husbandry. Cattle, sheep, goats and buffalo formed part of Harappan subsistence, with their relative importance varying by region. Animals provided meat and potentially milk, manure and transport or traction services. Herding also allowed households to use grazing environments unsuitable for crops. Fishing, hunting and gathering supplemented food supplies, showing that urban diets cannot be reconstructed from cereal cultivation alone.

Harvests required processing and storage. Grinding stones, charred grain, storage vessels and possible storage spaces provide evidence for these activities. Large structures at Harappa and Mohenjo-daro were traditionally described as granaries, but their exact functions remain disputed. They should not be presented as unquestionable proof of centralized state grain collection. Likewise, standardized weights and seals demonstrate organized exchange without revealing a specific agricultural tax system.

Food production underpinned craft specialization and urban populations, while cotton connected cultivators to textile manufacture. Rural–urban exchange probably moved food, animals and raw materials alongside finished goods. Yet the undeciphered script prevents confident reconstruction of land tenure, rent, prices, compulsory labour or the identity of institutions controlling surplus.

• Manure could improve soil fertility, but precise fertilization practices are difficult to reconstruct.
• The absence of readable administrative records distinguishes Harappan agricultural history from that of Mesopotamia.

5. Archaeological evidence and agricultural change

Agricultural reconstruction draws on charred seeds, grain impressions, phytoliths, pollen, tools, animal bones and field traces. Flotation separates light botanical remains from excavated soil and has greatly improved crop recovery. Each source has limitations: charring favours particular preservation conditions, impressions may come from transported material, and animal bones do not automatically reveal an animal's economic role. Older excavations often recovered fewer small seeds, potentially understating pulses and millets.

After about 1900 BCE, major cities contracted and settlement patterns became more regional. Changes in monsoon strength, river behaviour, trade and social organization have all been discussed as contributing factors. Agricultural adjustments included shifts in crop combinations and greater emphasis on locally suitable production. Neither a single flood nor a uniform drought explains all regions, and reduced urbanism did not mean the disappearance of farming.

For Prelims, match sites to specific evidence and watch for absolute wording. Statements asserting universal rice cultivation, iron agricultural tools, proven nationwide canal irrigation or an identical crop package everywhere are unsound. For analytical answers, agriculture should be understood as a flexible economic foundation whose regional diversity helped communities respond to environmental and social change.

• A secure answer separates excavated evidence from plausible reconstruction.
• Use the terms Early Harappan, Mature Harappan and Late Harappan carefully when assigning dates to agricultural discoveries.
