Rice In Sri Lanka - Crop Establishment
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
