| Abstract | A field experiment was established, to link the change in soil
physical properties by agricultural machinery wheels and their effect on
maize grain yield. Soil was compacted by wheel traffic applied uniformly to
cover the entire surface of experimental plots immediately before sowing
and after sowing, with number of passes varied between 0 to 5. Tyre
inflation pressure was kept constant.
Dry bulk density and penetration resistance were increased with the
increase in number of wheel passes and reverse was the case with porosity.
Maize yield was affected highly with a slight decreased in porosity. Yield
was 1.11 and 1.05 t/ha less for about 6% average decrease in soil porosity
at 0 to 20 cm depth in before and after sowing treatment respectively. |
