Does planting timing of green mulches affect yield of garlic and labour?

Research Priorities: Cover Crops
This project compared yield and labour for garlic planted into established oats, garlic and oats planted together, and garlic without a cover crop. Key Findings:
- Garlic survival and proportion of medium garlic was highest when garlic was planted with oats or into bare soil (control); and lowest when garlic was planted into an established oat cover crop.
- Garlic planted into an established cover crop required more planting labour and delayed emergence.
- Delayed emergence, in turn, delayed weeding and allowed perennial species to establish.
- Eric won’t use the oat treatments as tested again; but seeing the biomass of the early oat planting has motivated him to tweak the system to make it work.
