Can I increase my KCC limit after a few years and how?

Yes, you can get your KCC limit raised, and there are a few ways. The simplest is the built in annual step up: many banks increase the limit by around 10 percent each year automatically to allow for cost inflation, so check that this has been applied at your reviews. Beyond that, you can ask for a fresh assessment if your situation has changed: if you have added land, started growing a higher value or a second crop, or added allied activities like dairy, your scale of finance based amount goes up. Bring the current year's scale of finance sheet, your updated land records and your cropping details to the branch and request a revision. A clean repayment history helps a lot, because banks readily raise limits for farmers who repay on time. If you have crossed into a higher limit band, some extra paperwork or security may apply. Ask your branch for a limit enhancement form and the current scale of finance.
