Association of Legumes with Seed Crops to Reduce Nitrogen Inputs in Seed Production
This study evaluates the integration of legumes into seed production systems—specifically tall fescue sown under spring pea and carrot grown with inter-row legumes—to reduce synthetic nitrogen use while assessing agronomic, economic, and environmental outcomes.

Detail beschrijving
The paper reports two trials: one comparing tall fescue establishment under spring pea versus under barley or winter wheat across multiple sites and years, and another testing carrot seed production with various legume species sown between rows over a three-year period. Results show equal or higher fescue seed yields after pea, a neutral economic balance due to lower pea grain output, and improved environmental performance from reduced nitrogen applications. In the carrot trials, no significant nitrogen transfer was observed, though winter pea sown on three rows showed promise. The study identifies management adaptations and farmer training needs for adopting these innovative systems.
