Description: In the park belt region of the prairie provinces the need for fall tillage of stubble land which is to be seeded the next spring has been questioned on numerous occasions (9, 13). The removal of trash by burning combine straw, a practice condemned by conservationists (4, 9, 12) has been practiced consistently on many farms in the area. Several different types of machines are used with success for fall tillage. Tillage with these machines reduces the combine trash on the soil surface (1) facilitating trash clearance with seeding equipment (2, 10). Fall tillage has also been recommended (13) for the control of annual and perennial weeds. By working the land, crop and weed seeds are encouraged to germinate and be killed by winter freezing or preseeding tillage in the spring. Trash cover reduces erosion and improves the physical and chemical properties of the soil (4,12, 13,14,15). It has been shown (9) that at several locations on the prairies, heavy combine trash reduced the yield of the following grain crop. At all of these locations except Regina there were, however, trash management treatments that produced a yield that was not significantly different from that obtained where all the trash was removed by burning. At Brandon (12) it was found that straw applications had a beneficial effect on yields, while at Lethbridge (3) up to 4480 kg/ha of straw mulch had no deleterious affect on crop yields. The study reported here was con ducted at Brandon, Manitoba and Melfort, Saskatchewan to compare the effect of several methods of treating stubble on the yield of second crop wheat.
