Scots have just 24 hours to register for the September 18 referendum, which is also open to 16 and 17-year-olds for the first time in a major a poll.
Mr Salmond said: “With just 17 days of campaigning left, people who want to vote but aren’t yet on the electoral roll have just 24 hours left to sign up to take part in Scotland’s date with destiny.
“The truth about Scotland’s immense wealth is reaching people and communities across the country, who are waking up to the huge wealth of opportunity offered by a Yes vote.
“Hundreds of thousands of people, many of whom have never voted in their lives, are now engaged in the most exciting, participative and powerful debate in Scottish political history.
“Even the most ardent No supporters now accept that an independent Scotland would be one of the richest nations per head on earth - with human and natural resources that most countries can only dream of - but for too many people living here, it doesn’t feel that way.
“Independence won’t be a magic wand, but it will give Scotland the full tool-box of powers to help create more jobs, protect our NHS from the effects of Tory-led privatisation south of the border, and build a fairer and more prosperous nation.
“David Cameron said this weekend that he is ‘nervous’ about the referendum result - and he is right to be so, with the most recent polls putting a Yes vote within touching distance, and hundreds of thousands of Labour voters set to back independence as momentum is now firmly with the Yes campaign.
“If you have friends or family who want to vote and are not registered, they have just hours to do so - this is their last chance to seize the wealth of opportunity offered by Scotland’s historic referendum.”
