Expired lease on agriculture land

if a tenant continues to pay rent after a lease expires and the landlord accepts the rent, the lease is automatically renewed. The new lease is for the same length as the old lease and contains the same provisions.

A landlord and a tenant may also agree to extend the tenancy by signing a new lease agreement. The landlord can change the terms of the lease and increase the rent. If the tenant agrees to the new terms, the new lease governs the tenancy.

Thanks for the response Mr.Ramachary. In this case, the landlord have not received any rent after the lease expired. Also the lease was signed when the current owner's husband was alive in whose name the property was registered. Since he is no more, the property automatically comes under the control of his wife who is willing to sell it to us (All patta/chitta docs are in wife's name). The lessee who is one of the relation to the owner is not in good terms and hence the owner did not ask for lease cancellation. The land is still uncultivated from the beginning. Is it a must to have a formal lease cancellation in this case and register it or we can go ahead and buy this land only with owners willingness?
