We present a measurement of t{ovr t} production in p{ovr p} collisions at {radical} (s) =1.8 TeV from 110 pb{sup {minus}1} of data collected in the all-jets decay channel with the D0 detector at Fermilab. A neural network analysis yields a cross section of 7.1{plus_minus}2.8(stat){plus_minus}1.5( syst) pb at a top quark mass (m{sub t}) of 172.1 GeV/c{sup 2} . Using previous D0 measurements from dilepton and single lepton channels, the combined D0 result for the t{ovr t} production cross section is 5.9{plus_minus}1.2(stat){plus_minus}1.1( syst) pb for m{sub t}=172.1 GeV /c{sup 2} . {copyright} {ital 1999} {ital The American Physical Society}
