For the purpose of this clause the amount of tribute payable by a Jagirdar to the Government for the agricultural year 1950 51 shall be deemed to be the amount of such tribute less the amount of any tribute payable to such jagirdar by any person to whom the Jagirdar may have granted any of his jagir lands; (c) for the agricultural year 1959 60 and subsequent years, one fourth of the rental income from the jagir lands as determined under sections 6 and 7; Provided that (i) where no tribute was payable by the Jagirdar before the commencement of the Act or where the whole of the tribute has been paid before such commencement, the jagir lands shall be deemed to be exempt from the payment of land revenue for the agricultural year 1951 52; (ii) where the jagirdar has paid a part of the tribute before the commencement of this Acts, the land revenue payable by him for the agricultural year 1951 52 shall be an amount equal 'to the balance of the tribute which would have been payable by him for that year if this Act had not been passed; and (iii) the Government may direct that for the purposes of clauses (b) and (e) of this section, the rental income of any jagir land for all or any of the agricultural year mentioned in those clauses shall be 448 determined or redetermined on the basis of the rental income which actually accrued to the jagirdar from the jagir in such year or years, as the case may be." It will be seen that this section speaks of tribute payable for the, year specified 1951 52 or 1950 51and it is obvious that the tribute here referred to could only be the recurring payments like those enumerated in the definition in section 2(r) to which could be attributed the character of being a payment for a specific year.
