Aims

To evaluate the impact of tillage treatments on wheat yield in a number of farmer demonstrations. 

Key messages
  • Growing wheat in an area with a growing season of 140-175 days and only 220 mm of incrop rainfall, benefits from at least one deep cultivation (15-20cm) prior to sowing.
  • The timing of cultivation of a chemically fallowed pasture is probably unimportant. If an erosion risk is present then cultivation should be delayed as late as practical.
  • Reduced tillage systems are becoming more widely adopted by central western wheat farmers. It is suggested that most farmers could increase their average yield by 10% if they modify their chisel plough to a one pass plough. For design modification contact Alan Palmer at Trangie Agricultural Research Centre.
