The top quark pair production cross-section σ_tt has been measured in pp collisions at center of mass energies of 1.96 TeV using Tevatron Run 2 data. In the begining of Run 2 both CDF and DØ σ_tt measurements in the \it dilepton channel tt→WbWb→ℓνℓbℓ' barν_ℓ'b and in the \it lepton plus jets channel tt→WbWb→qq'bℓνℓ b+ℓνℓbqq'b agree with the NLO (Next-to-Leading-Order) theoretical predictions. The presence of a top signal in Tevatron data has been reestablished.
