If I already have a crop KCC, can I add a separate limit for dairy on the same card?

You can usually add an allied activity limit to your existing KCC rather than opening a completely separate card. Many banks set a combined KCC with a crop sub limit and an animal husbandry or fishery sub limit within the same account, each assessed on its own basis: crops on scale of finance, dairy on per animal maintenance cost. So bring proof of your new dairy, such as the number of milch animals and a basic plan from the veterinary department, and ask the branch to enhance your KCC by adding a dairy sub limit. The crop part keeps its own due date tied to the crop cycle, and the dairy part its own working capital cycle. The prompt repayment benefit applies within the eligible ceilings. Whether the bank adds a sub limit or issues a second product depends on its system, so ask your branch how they prefer to structure crop plus dairy and what proof they need for the animals.
