Zero tillage

Objective

• An extreme level of Minimum tillage, currently not practiced prominently as there is a limitation of broad-spectrum preplant herbicides
• To reduce the requirement of time, labor and fuel costs required in conventional land preparation
• To reduce damage to soil structure

Method of operation

• As the name implies, there will be no Land preparation practiced
• Pre-emergent herbicides are used to control weeds before sowing
• Seed paddy that are soaked in water for 48 hours and incubated for 24 hours are broadcasted on to the moistened soil at the onset of rain
• Seven to ten days after germination, fields will be  inundated  with water and selected herbicides could be used to control weeds

Important considerations

• Higher rate of seed paddy (150-250kg/ha) is used with this method too
