If Austrian winter peas are left in until they flower in May, nitrogen fixation may be even higher, up to 200 lb per acre. Mow or roll the crop to kill it after flowering, especially if grown with rye for support, acts as a mulch. Seeding Rate: Sow in early to mid-fall at 2-3 lb/1,000 sq ft or 88-130 lb/acre.
