The Williams brothers talked shop about what makes the Big Bud unique, what it does on their farm and what their no-till model looks like. Effect of soil temperature, soil water potential, and seeding depth on emergence of winter wheat. This, along with timely planting, is critically important if improving wheat performance is the goal. Table 2. 2 An estimated emergence rate is given in brackets as percent. For those trying to estimate the odds of achieving a reasonable yield, it is important to recognize that the challenge to late wheat is not only the inherent constraints on grain yield, but also its greater susceptibility to winter injury. Issued in furtherance of MSU Extension work, acts of May 8 and June 30, 1914, in cooperation with the U.S. Department of Agriculture. Tillage can also be useful when attempting to reduce disease inoculum borne in crop residue (e.g. However, planting wheat prior to that date is generally not encouraged as the crop may be at greater risk from viral and fungal diseases. Most farmers grow and store their own seed for use in the following year. Attaining a consistent seed depth is important in that it will increase the probability of even emergence. Adding weight to the drill may help in penetrating crop residue (or hard soil). RealAgriculture Agronomy Team . Jeffrey W. Dwyer, Director, MSU Extension, East Lansing, MI 48824. Guidelines on optimal stand, pounds of seeds per acre and planting depth. To retain snow during the winter, directly seed winter wheat into standing crop stubble. Target seeding rates (millions of seeds per acre). It is a viable alternative to a traditional spring wheat seeding program and as a means to keep wheat in the rotation when dry weather precludes winter wheat seeding in the fall. Wheat seed should be planted 1-1½ inches deep if soil moisture is adequate. While the Hessian fly no longer poses a significant threat to wheat in Michigan, the fly-free-date is still a useful reference (Table 1). These depths help reduce the risk of winter injury and heaving. Relating seed size and target seeding rates to the number of pounds required per acre, Target seeding rates (millions of seeds per acre), Actual pounds of seed required per acre *. To facilitate rapid emergence, seed winter wheat at a 1- to 1.5-inch soil depth. Achieving top yields requires a uniform stand of healthy seedlings. MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. Seeding in narrower rows or increasing seeding rate may have an advantage in dry weather but be sure not to cut corners in a dry fall planting to be sure the wheat is off to the best start before winter. Table 3 is useful for assessing the number of seeds being dropped by each row unit (7.5-inch row spacing) and for evaluating actual emergence. For example, if seed size is 12,000 seeds per pound and the target seeding rate is 1.4 million seeds per acre, then 117 pounds of seed would be needed per acre. Planting date: The optimal window for dual-purpose wheat for most of Oklahoma is between September 10-20 (approximately day 260 in Figure 1). In this case, the seed should be placed as deep as necessary to find moisture. Planting Time: Mid – Late Fall; Seeding Rate: 80-100 lbs/acre; Drilled Seeding Depth: 1” – 1.5” Winter wheat should be planted in the fall when conditions will allow it to germinate before entering a dormant winter period in which it will vernalize. Attaining a consistent seed depth is important in order to increase the probability of even emergence. * Seeds per ac / seeds per lb = lbs of seed per ac. Seeding date is more important for canola than for wheat. The shallower the planting depth, the sooner the seedlings can emerge and commence photosynthesis and the earlier that tillering can start. Generally speaking, no-till has won favor in recent years. The seeding rates should also be adjusted upward when seed is of questionable quality. To contact an expert in your area, visit https://extension.msu.edu/experts, or call 888-MSUE4MI (888-678-3464). To attain top yields, the goal of the planting operation needs to be an even and uniform stand of seedlings. PLANTING DATE. The 2018 growing season had its challenges with a cool, wet spring followed by hot, dry weather during the critical grain fill period. For more information, visit https://extension.msu.edu. Generally, a seeding rate of 900,000 to 1.2 million viable seed per acre is adequate. Ideally, winter wheat is planted while the soil and air temperatures are still warm to ensure that seedlings can emerge quickly and in plenty of time to develop a couple of tillers and a strong root system. RealAgriculture Agronomy Team. Seeding shallower than an inch deep puts the crowns at a higher risk for winter kill, while seeding deeper will delay emergence. Heaving occurs during periods that soil freezes and thaws. Particularly for no-till operations, bunched-up residue is the most common threat to evenness in wheat stands. Wheat School - Winter Wheat: Stubble Selection, Seeding Depth & Weed Control. The standard fly-free-date is during the first week of September in the northern Lower Peninsula, around mid-September in mid-state areas and approximately the third or fourth week of September for southern Michigan. It tends to result in more unevenness in the stand, but it can often provide improved moisture retention and less susceptibility to cold temperature damage.

On the other hand, deep seeding will delay emergence which can result in a rather thin, spindly plant that is much more susceptible to winter kill.
