Submitted by: agcomm, Thu Sep 25 10:59:00 1997 September 25, 1997 Dormant Seeding Can Be Helpful, But Involves Some Risk Dormant seeding of wheat or rye can reduce the spring work load and in some cases improve yield slightly, but it is not without risk, according to Mike Peel, agronomist for the North Dakota State University Extension Service. The main risk is that Indian Summer or a mid-winter warm spell will initiate germination and seedling growth, and cold temperatures will then kill or injure the young plants. Dormant seeding of winter wheat, spring wheat or rye is done before the soil freezes in the fall. In North Dakota this varies from two weeks to 10 days from north to south, and is usually in the first week of November, says Peel, though in some years it can be much later than that. Once planted, the seeds will adsorb moisture but will lie dormant until spring--unless, that is, they encounter a warm spell before then. As the soil warms in the spring, the seedlings will start growing and often will establish themselves before spring planting is finished. One advantage of dormant seeding, says Peel, is that the crop gets a jump in spring and may not be damaged by short periods of early season drought, such as North Dakota farmers experienced this past June. Will dormant seeding improve yield? There are some reports, says Peel, of dormant-seeded wheat outyielding spring-seeded wheat, but the major advantage of dormant seeding is in lightening the spring work load. Peel offers these points for producers to consider as they contemplate dormant seeding this fall: The more winter-hardy winter wheats, when dormant-seeded, tend not to mature any earlier than spring wheat. * Dormant-seeding wheat into a conventional-till seed bed could lead to crusting problems in the spring. Dormant-seeding into crop residue will eliminate or substantially reduce this possibility. * Using a seed fungicide treatment is recommended when dormant-seeding wheat. Trials have shown improved stands and yields when the seed is treated with Apron and Dividend. ### NDSU Agriculture Communication Source: Mike Peel (701) 231-8037 Editor: Barry Brissman (701) 231-7866
