  2. The Farm Science Review will be held again this year at the London, Ohio location. Dates are September 19, 20 and 21. See http://fsr.osu.edu for more information. Harvest has not quite stared yet so you should have the time to check in.

    The Agronomic Crops Team (http://agcrops.osu.edu) will once again be welcoming visitors on the east side of the grounds between the parking lot and the exhibit area.

  3. Soybean aphids
    Author(s): Andy Michel , Author(s): Kelley Tilmon

    We have heard reports of growers spotting a few soybean aphids in their fields. Finding aphids at this time of year is consistent in the past—we have seen them arrive later and later. We do have a lot of late-planted soybean that are in R4 or R5 stage soybean. Remember that our economic threshold to treat soybean aphids is a rising population of 250 aphids per plant. But also remember that, at higher growth stages (>R6) the threshold increases dramatically. At this point it is important to note that none of the fields in Ohio have reached treatable levels.

    We have had the opportunity to walk additional Ohio fields where soybeans were damaged by off-target movement of dicamba since our last C.O.R.N. newsletter article on this subject (see link below), and we continue to hear about even more affected fields.  This situation continues to develop across the Midwest and South, and everyone involved is trying to assess causes and what these mean for future use.  A couple of action items here for anyone associated with an off-target dicamba movement and injury situation:

    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.

  6. field day
    Author(s): Amanda Douridas

    Join specialists in the field this summer to see hands on what insect and disease pressure is present. The specialists will help participants identify insects and diseases and then discuss management strategies. The series begins with a Pasture Walk on May 23 at 5:30 pm. The field borders the Ohio Caverns so an optional group tour of the Caverns has been set up at 4pm ($15).

    Saturated soils after soybean planting can cause uneven emergence and stand reductions of varying extent depending on the stage of the soybean plant and other environmental factors including temperature and duration of saturated conditions. Additionally, increased disease incidence may further reduce plant stand.

    Saturated Soil Prior to Germination: While soil moisture is necessary for germination, soybean seeds will not germinate when soils are saturated because oxygen is limiting.

    The Soybean and Small Grain Crop Production Lab is pleased to present the first edition of the Ohio Soybean and Wheat Research Report: https://stepupsoy.osu.edu/sites/hcs-soy/files/Soybean%20and%20Wheat%20Trials%202016%203.pdf. This publication contains the final reports of soybean and wheat research trials conducted between 2012-2015 including high-input soybean production, soybean planting date x starter fertilizer, and wide-row wheat production.

    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:

    2013, 2014, and 2015, with funding from Ohio Soybean Council and help from county extension educators, we measured soybean yield limiting factors on 199 farms across the state. Data collected included management practices (i.e., crop rotation, variety, row width, etc), soil fertility status, soybean cyst nematode (SCN) egg counts, and soybean yield. These were the top yield-reducers in our research:
