The CDF and D0 experiments have measured the t{bar t} production cross section in p{bar p} collisions at {radical}s = 1.96 TeV from different final states using a wide variety of techniques. CDF has combined 6 measurements using data samples with integrated luminosities up to 760 pb{sup -1}: {sigma}{sub t{bar t}} = 7.3 {+-} 0.5(stat) {+-} 0.6(syst) {+-} 0.4(lum) pb in good agreement with the theoretical calculations: 6.7 {+-} 0.8 pb for a top mass of 175 GeV/c{sup 2}. The experimental precision of the current CDF combined result is comparable for the first time to the accuracy of the QCD NLO theory: {approx} 12%.
