Can I claim subsidy on more than one scheme at the same time?

In general you can claim subsidy on different items under different schemes, because drip under PMKSY, a tractor under SMAM and a polyhouse under MIDH are separate components with separate budgets, and getting one does not block another. What you cannot usually do is take two subsidies for the same item or the same purpose from two schemes at once, that double dipping is checked and rejected. Most schemes also have a per beneficiary limit, for example one tractor per family in a fixed number of years, a maximum drip area, or a maximum polyhouse area, and several enforce a cooling period before you can claim the same item again. Some states cap total assistance per family per year across schemes. So plan a sequence: take the items you need most across the open windows rather than expecting everything in one year, and keep within each item's per beneficiary cap. Confirm the per item caps, cooling periods and any family level ceiling for your state on the official portal, because these vary and change with each year's guidelines.
