Arugula is a fall-seeded, overwintering Brassica. It is useful for suppressing weeds and minimizing surface compaction. Arugula provides less ground cover but more biofumigation potenial than turnips or rape. The glucosinolates in Brassicas are the compounds responsible for disease suppression.

Land preparation

Smooth seedbed free of weeds and well-drained. Must contain sufficient moisture.

Seeding rate

Drill 2-4 lb/ac, 1/4-1/2 inch deep.
Broadcast.
Seed can be no-tilled into suppressed sod or seeded into a conventionally prepared seedbed. When using conventional tillage, control the first flush of weeds before seeding to ensure a weed-free seedbed. Roll after seeding to improve seed-to-soil contact but do not break up aggregates.

Seeding date

August.

Seed Sources

Rupp Seeds. (seed sources)

Maintenance

Avoid wet spots.

Control

Incorporate in the spring. For biofumigation, mow when the soil is warm but before seed set. Incorporate immediately and roll soil to seal the surface. Wait a minimum of 10 days to fit and plant.

Tips

Do not use in rotation with other Brassicas.
Brassicas can be magnets for flea beetles.
Arugula is reported to reduce the populations of Northern root knot nematodes on tomatoes.
