Applicability of MCLR on KCC Loans

Hii

I want to know whether the MCLR is applicable for KCC loans or not.

As i have seen in One KCC Account that the Bank is Charging higher interest on Crop Loan for not submitting  the documents like Stamp paper for MCLR and Other. So Pls let me know whether that is mandatory to submit the documents for MCLR or whether it not required and Bank should reverse the higher interest charge by them.
