The infrared behaviour of QCD in the Landau gauge is studied in 244 and 324 lattices by measuring the Kugo-Ojima parameter, gluon propagator, ghost propagator and the QCD running coupling. The Kugo-Ojima parameter c remains about 0.8 instead of the expectation value 1. We observe infrared suppressio
