Abstract
Methods of mulch-planting were compared with mouldboard-ploughing methods for corn production at Woodslee during 1953, 1954 and 1955. The tillage treatments were established in second-year alfalfa sod on Brookston clay soil. On the basis of corn yield the conventional ploughing treatments were greatly superior to any mulch-plant method tested during the three years. Soil moisture studies indicated that the effect of the intercrop on the soil moisture supply was the major factor influencing crop yield, but moisture alone did not account entirely for the differences obtained in crop yield. The plough-plant method produced as good corn yields as spring ploughing in 1953 but somewhat less in 1954 and 1955. The results would suggest that an adaptation of the plough-plant method may have possible application as a tillage method for corn on the finer textured soils of southwestern Ontario.
