  1. Bee on dandilion

    Beekeepers in Ohio benefitted from the generally mild winter of 2015-2016.  In Columbus we lost less than 20% of our colonies over winter.  Spring is the only reliably good season for bees in Ohio.  Colonies that survived the winter and new colonies brought up from the Gulf Coast or California are currently in the process of harvesting nectar and pollen from spring-blooming trees and weeds.  Little honey will be made from this spring bounty as most will be eaten by the bees themselves as they multiply and grow into large productive colonies that will be able to make a honey crop off of clov

    This is our last week to collect data for our soybean yield-limiting project. The online survey can be found here:  https://www.surveymonkey.com/r/ohiosoybean  All data will be treated as confidential.  If you provide your name and email, you will receive a state and regional summary of the results.

    Planting date.  Planting date (both too early and too late) can reduce soybean yield potential.  In 2013 and 2014, we conducted a planting date trial at the Western Agricultural Research Station near South Charleston, Ohio.  In both years, soybean yield decreased by 0.6 bu/ac per day when planting after mid-May.  (Note: Soil temperatures were >50°F at each planting date.)  The greatest benefit of planting May 1 to mid-May is canopy closure which increases light interception, improves weed control by shading out weeds, and helps retain soil moisture.

    I ran this article last week.  Thank you to all who filled out the survey!  Our goal is to document soybean management practices and yield from 270 soybean fields in Ohio during the 2014 and 2015 growing seasons.  Right now, we are 185 fields short of our goal, but we are continuing to collect data through the month of April.

    These warm days have the engines warming for an early planting but the soil temperatures from around the state are highly variable and still on the cool side.  From the weather stations at the branches, these are the soil temperatures at 2.5 inches, from March 21:

  6. Soybean cyst nematodes
    Author(s): Anne Dorrance

    These fluctuating temperatures that we have had this spring where we go from snow days to short days provides some opportunities to get the crews out and enjoy some nice weather.  Sampling for Soybean Cyst Nematode is fine to do in the spring, especially in years where the ground thaws early. 

    It is becoming increasingly important in Ohio to know your numbers.  Sounds like a cholesterol warning doesn’t it?  In the case of SCN, less than 500 eggs per cup of soil and keeping it under 1,000 is what we need to shoot for on some fields.  Non-detectable levels are like gold.

    LibertyLink soybeans are finally starting to get the use in Ohio that they deserve.  Use of the LibertyLink system accomplishes several things - resolving current herbicide-resistant weed problems and reducing the emphasis on glyphosate use that continues to drive the development of resistant weed populations.  Our primary glyphosate weed problems in the state are still marestail, giant ragweed, and common ragweed.  Waterhemp problems are slowly increasing and Palmer amaranth is showing up here and there.  Glyphosate resistance in these species often occurs in conjunction with site 2 resist

  8. Soybean
    Author(s): Laura Lindsey

    As I travelled the state this winter, the same question came up, “What’s limiting soybean yield?  No matter what I do, I get the same soybean yield every year.”

    While we are interested in improving yield of Ohio crops, we also are reluctant to recommend practices that cost time and money and are not likely to be of assistance. From several on-farm trials conducted by OSU Extension professionals over the years, we see no value in applying sugar to our Ohio row crops.

    Looking for ways to maximize soybean yield and profit?  Attend one of the 2016 Ohio Intensive Soybean Management Workshops offered by The Ohio State University Extension.  This workshop will be hands on and open to producers and agricultural professionals.  The workshop is occurring at three locations:

    1.       February 9, 2016:  Clinton County Extension Community Room, 111 S. Nelson Ave., Wilmington

    2.       February 24, 2016:  Evolution Ag, 13275 U.S. Rt. 42, Plain City
