[short_answer] Rice is grown as a subsistence crop in Odisha but as a commercial crop in Punjab — both regions cultivating the same crop under broadly similar agro-climatic conditions. What factors account for this difference, and what does this tell us about how 'commercial' versus 'subsistence' farming is determined?

Model Answer
The textbook directly states: "Rice is a commercial crop in Haryana and Punjab, but in Odisha, it is a subsistence crop."
The difference lies not in agro-climatic conditions but in socio-economic factors:
- Punjab uses high doses of modern inputs (HYV seeds, chemical fertilisers, irrigation via canals/tubewells) and produces surplus for the market — this is commercial farming.
- Odisha relies on traditional methods with limited inputs; output mainly meets the farmer's own needs.
This shows that whether farming is 'commercial' or 'subsistence' is determined by use of modern inputs, market orientation, and degree of commercialisation — not by the crop itself.

Explanation
- The textbook gives this exact rice/Punjab/Odisha example under "Commercial Farming" — quote it directly for full marks.
- Examiners look for: (1) the contrast stated, (2) reasons (inputs, surplus/market vs. self-consumption), and (3) the principle that commercialisation depends on how farming is done, not which crop.
- Avoid writing about climate differences — the question says conditions are "broadly similar," and the textbook's point is that economics/technology decides the type, not the crop.
