The effectiveness of no-till forage establishment was assessed at six locations in Alaska. Direct seeding of grass into established grass stands usually did not improve forage yields or quality. Seeding rate and N rate had little effect on establishment of newly seeded forages, especially in no-till. Grass yields were depressed when companion crop yields were high and sometimes did not recover in subsequent years. Red clover established well, producing high yields of good quality forage under no-till at one site, but established poorly at two other sites.
The objectives of this project were to:
1. Evaluate the efficacy of no-till planting as compared to planting into tilled soil under various N fertilizer rates for establishment of timothy (Phleum pratense L.) and smooth bromegrass (Bromus inermis Leyss.) in Alaska.
2. Evaluate promising annual companion crops for forage production during perennial grass establishment in no-till and conventional tilled planting systems.
3. Determine the effectiveness of no-till establishment of perennial grasses and red clover (Trifolium pratense L.) at various seeding rates.
