You don't necessarily have to put in more seed than you have in the past. 2 MATERIALS AND METHODS Response of spring wheat to varying seeding rate and nitrogen management. Many of the seasoned winter wheat producers, plant at 1.1-1.2 million PLS (pure live seeds) per acre. Excessively high seeding rates can result in more lodging by harvest time, particularly if you are using a taller variety (like Jerry). Hard White Wheat: Producing North Dakota's Next Market Opportunity; . Seeding shallower than an inch deep puts the crowns at a higher risk for winter kill, while seeding deeper will delay emergence. Recommended seeding rates for these mixes are included in Table 2. Seeding rates on the lower end of the range should be used when planting within a week of the fly-free-date to avoid overly thick stands that can promote disease development and increase the likelihood of lodging the following season. Delay in planting reduces yield potential and tiller development. If determined by the number of seeds per acre, it can vary by 4.2 times. Seeding rate, N level, and N application timing are key management factors for spring wheat (Triticum aestivum L.) production in North Dakota.Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions in 2003 to 2005 to determine the optimum combination of seeding rate and N management to maximize yield of hard red spring wheat (HRSW). The most-planted wheat variety in North Dakota two years in a row, SY Ingmar has very high protein potential, broad adaptation, excellent standability and medium maturity for greater yield potential. North Dakota State University Extension has developed a spreadsheet to help farmers make informed prevented-planting decisions. North Dakota Dry Pea Harvested Acreage, 1999 to 2021. When weight is used for wheat seeding rates, a seed size difference of this magnitude can result in a 153% difference in seeding rate. Figure 1: How planting date affects the number of heads per square foot of hard spring wheat at harvest in Langdon, North Dakota. Example of the the equation: 110 lbs per acre = ( (1.1 million seeds per acre)/ (1-0.15)) / ( (12,500 seeds per lb)x (0.95)) Nebraska growers use seeding rates for winter wheat that can vary from 30 to 180 lb per acre (300,000 to almost 4,000,000 seeds per acre = 13.3) if the lower rate is with a large seed and the higher rate is with a small seed.
