    Soybean planting date is absolutely critical to maximize yield (in most years and environments). Over the past few years, we’ve participated in a North Central Soybean Research Program (NCSRP) funded project with the goal of identifying causes of the “soybean yield gap.” (What factors are reducing soybean yield?) Across the Midwest, planting date was the most consistent management factor that influenced soybean yield.

    Persistent wet weather prevented soybean planting in many areas of the state. Late planting reduces the cultural practice options for row spacing, seeding rate, and relative maturity.

  4. brown, diseased emerging soybean plant. PPO and cold injury
    Author(s): Anne Dorrance , Author(s): Mark Loux

    Several calls last week with pictures of injured and/or diseased soybean seedlings.  For most of these situations we have the following scenario:  PPO herbicides (flumioxazin, sulfentrazone, saflufenacil) included as a component of the preplant burn down, fields planted 7 days later with fungicide treated seed, followed by 1 to 2 weeks of suboptimum growing conditions (between 40 to 50oF) for 2 weeks, and greater than 2” rain.  These conditions are very conducive to both Pythium damping-off and PPO injury.

    Over the past few years, with funding from Ohio Soybean Council, we’ve re-examined Ohio’s soybean planting date, row width, and seeding rate recommendations. Here are some things to keep in mind, as we approach planting:

    Decisions made at planting time are critical in getting any crop off to the best possible start. The technology and agronomic research we have today can help farmers maximize planter performance for optimal crop yields. Join OSU Extension and Champaign County Farm Bureau on August 26 for the second annual Precision Ag Day. This year the focus will be on planter technology.

  8. frost damaged soybeans
    Author(s): Laura Lindsey , Author(s): Peter Thomison

    Soybean: Last Monday, May 16, air temperatures dropped to high 20s/low 30s causing some freeze injury to soybeans. Soybeans in low areas of the field are most likely to be affected. Plants should be assessed for damage at least five days after suspected injury to inspect for regrowth. If damage occurred above the cotyledons, the plant will likely recover. If damaged occurred below the cotyledons, the plant will not recover. Look for a discolored hypocotyl (the “crook” of the soybean that first emerges from the ground) which indicates that damage occurred below the cotyledons.

    Wet weather has kept many farmers (and us) out of the field.  According to the USDA National Agricultural Statistics Service, as of May 15, 10% of the soybean acres were planted.  At the same time last year, 46% of soybean planting was complete.  On average, in Ohio, the majority of soybean acres are planted mid to late May (Table 1).  Although, it is not uncommon for soybean planting to creep into June.  In general, we don’t recommend altering soybean management until planting in June.  Below are some guidelines to consider if planting soybeans in June.

  10. Exact emerge planter
    Author(s): Mary Griffith

    With the ever changing weather pattern, it is critical that farmers take advantage of prime planting opportunities. Planting as efficiently as possible is one key to a successful season. Planters and technology have a come a long way in recent years. From seed singulation and uniform spacing to variable rate seeding and fertilizer application, we are working towards every seed producing its maximum yield. One of the newest planting systems is the John Deere ExactEmerge row unit, which allows planting speeds of up to 10 mph.
