"In Maharashtra, if our alliance wins less than 45 seats, it will not be deemed a victory," Shah said.
While the Shiv Sena and BJP had contested the last Lok Sabha election together, it is not yet clear whether the alliance would continue this time given their strained relations.
"I want my party workers to win me 45 seats from the state, and to achieve that we will have to win Baramati seat. If we win Baramati, the number 45 can be achieved," the BJP chief said.
Baramati, Pawar's home turf, is at present represented by his daughter Supriya Sule.
"Not a single seat should go to the people who were involved in corruption in Maharashtra... not a single seat should be left to the people who talk about human rights of immigrants," the BJP president said.
State BJP chief Raosaheb Danve in his speech expressed confidence that they would win 43 seats, one more than in 2014.
Last time Rashtriya Samaj Paksh leader Mahadev Jankar, an NDA ally, lost from Baramati by a small margin, he said, adding, "Had there been the lotus symbol, we would have won Baramati. This time we will not make that mistake. Our candidate will fight on the party symbol.
