Wheel traffic effects on corn growth
1995
Ngunjiri, G.M.N. | Siemens, J.C.
Corn growth as affected by soil compaction due to wheel traffic before secondary tillage was studied. Compaction treatments included none, between rows, on rows, and on entire plot area. Corn yields with wheel traffic on entire plot area averaged 9.8 Mg/ha which was significantly lower than yields with the other treatments which averaged 12.5 Mg/ha with no traffic and 12.6 Mg/ha with traffic between rows and with traffic on rows. Corn plant height and dry matter weight throughout the growing season, and root mass assessed soon after tasseling, were also lower with wheel traffic on entire plot area compared to the other treatments.
