Mayawati urged the voters to support BSP "which is the only party which does not make castles in the air, but does work on the ground".
Earlier, addressing a rally in Ambala in Haryana, she said voters must elect maximum BSP candidates so that the balance of power remains with the party which would enable it to play a crucial role in government formation at the Centre.
She dubbed both Congress and BJP as "puppets in the hands of capitalists".
Hitting out at UPA, Mayawati said there was an apprehension that the government wants to do away with reservations for SC and BC as "without correspondingly increasing the quota, more and more castes were being included for reservation."
"This time you will have to show good results, so that BSP emerges as a strong force at the Centre...Like UP, we will run the government at the Centre which will work for welfare of all sections," she said and spelt out other steps which BSP will take, if it comes to power.
She highlighted her government's achievement on law and order front and prevention of riots by strictly dealing with such situation at the very outset in Uttar Pradesh.
"During our rule, among our main achievement was to maintain communal harmony and to work for welfare of all sections of the society," she said.
She claimed that if voted to power her government will work for the poor, downtrodden and other deprived sections, unlike the UPA and NDA coalitions which promise much, but fail to deliver.
In an obvious reference to opinion polls, Mayawati said parties opposed to BSP try to project their strong footing through the media and asked the voters not be misled by this.
She also said that to woo voters before the polls, new policies are framed by the government at the Centre, but these often get dumped when they come to power later on.
"You also have to be wary of the poll manifestos of parties as not even half of promises are kept when they taste power. Don't be influenced by false claims they make. We do not issue such manifestos, because we believe in doing work on the ground rather than making mere promises," she said.
