It has previously been an insurance to overseed just to be sure that we received the proper stand since seeds were not very expensive, but who can afford this today? How to avoid yield loss with late-planted soybeans. Research Institution. While shorter season varieties will not gain yield potential with an earlier planting date, a longer-season variety will, adding another couple of nodes of pods when planted earlier compared to later. A good method to estimate your stand is to count plants per 10 feet of row, then divide this number by 10 and use Table 2 to determine plants per acre. Planting depth surveys revealed that only 20 percent of the fields planted with drills were planted at or near the intended depth. Table 3. Timely planting is critical for maximizing yield in soybeans, but using good judgement on field conditions plays a role that is equally important to determining yield potential. Strategic Farming: Let's talk crops! Haul manure? The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. The recommended soybean planting depth is 3 - 4 cm, and the seed rate varies significantly according to local conditions.
