Is partial tilling advisable in no-till system?
Tillage with a disc plow or harrow or cultivator adds to the cost. Therefore if it is possible to manage weeds with out tilling the land it is advisable to keep practicing no-till system. However, in some situations such as planting wheat after sugarcane it becomes necessary to use a disc harrow to make it easier to work with a zero-till drill for wheat planting and avoid damage to drill from the sugarcane root stocks. Tillage may also become necessary if weeds are a problem and it is difficult to control them otherwise.
