Description

Two on-farm trials were established in 1994 to investigate low cost crop residue management and seeding practices in two cultivars of annual ryegrass (Lolium multiflorum Lam.) grown for seed production in Oregon's Willamette Valley. Sites varied by soil type and drainage. Stand density was greater in no-till and volunteer established plots at both locations, but straw removal by baling had no effect on stand density. Fertile tiller number and seed yield was reduced in drill sown plots in TAM-90 (poorly drained site); also, fertile tiller number was fewer where no straw removal preceded no-till or volunteer establishment. No difference in spring tillering characteristics or seed yield was observed in Gulf (better drained site).
