Book orders were up to RON824.3 million, but the ministry only sold the planned amount, central bank data showed.
The bond was last reopened in September, when the ministry raised RON234.8 million, less than half of the target, at an average yield of 3.54% a year.
The issue will be reopened tomorrow in a bid to raise RON45 million at a supplementary non-competitive sale.
The ministry plans to sell almost RON4 billion in state treasuries in October.
So far in 2014, the country sold RON31.2 billion in leu-denominated notes and EUR928.7 million at four euro-denominated auctions on the local market.
The ministry also tapped international markets for $2 billion at a two-part U. S. dollar bond issue in January, and raised EUR1.25 billion in a ten-year Eurobond sale in April. (EUR1=RON4.4176)
