Stale seedbed technique
Stale seedbed technique is most appropriate to reduce the weed seed bank in the soil.
In this technique, weeds are allowed to emerge for at least 2 weeks before being killed.
To do this:
- Perform tillage operations. Plow, harrow, and level the field.
- Stimulate weed emergence by light irrigation or after rainfall.
Give one irrigation at least 2 weeks before sowing. Maintain enough soil moisture to allow weeds to germinate.
- Kill the emerged seedlings using non-selective herbicides (e.g., glyphosate) or light cultivation.
- If the soil condition is suitable for sowing, plant the crop without further tillage operations. Tillage could bring more weed seeds near the soil surface, thus promoting weed germination.
Remember: Weeds must be actively growing at the time of post-emergence herbicide application. Different types of weed emerge at different times.
