Technical Abstract: Field trials were conducted over a ten year period to evaluate the utility of direct seeding and full chop residue management in three distinct grass seed production environments in western Oregon. The three primary seed crops were perennial ryegrass, tall fescue and creeping red fescue. Costs of establishing the crop were significantly reduced by direct seeding, with cost savings ranging from $27 (tall fescue) to $162 (creeping red fescue) per acre due to reduced field preparation expenses. In some cases, direct seeding increased seed yields and in no case were seed yields reduced. Maximum residue management also had no adverse impact on seed yield in these three production systems. Concern has been expressed by some growers that utilize these practices that slug and insect populations have increased and that these increases may be associated with the increased residue load.
