  1. Soyean planting rate chart

    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.  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.

    My dog, Lily, and I were dodging ice patches on our nightly walk this week and could finally sense a hint of spring.  It is time to start getting ready for the field season.  As I look back over my data and pictures of wipe outs in Ohio, the biggest losses have occurred when the super susceptible soybean variety or corn, or wheat, was planted into a field where inoculum (pathogen population) was high and environmental conditions often occur.

    There are a bunch of residual herbicide premixes available now for use in soybeans.  Most of these are listed in the 2015 edition of the Weed Control Guide, but it seems like there’s always one or two that we don’t know about.  Many new premixes are essentially generic versions of products that had already been available.  Example – Boundary, Ledger, and Tailwind are premixes of metribuzin and metolachlor from different companies that are essentially identical in formulation and label.  Once there are more than a couple of trade names for the same herbicide or herbicide premix, we usually l

    The purpose of the Ohio Soybean Seed Treatment and Foliar Trials are to evaluate soybean seed treatments and foliar products for stand and yield.  This evaluation gives soybean producers comparative information for selecting soybean seed treatments and foliar products for the unique production systems.  All entries were submitted voluntarily by companies.  Application protocol and product rate were provided by the company.  Please keep in mind that our trials are conducted in overall high-yielding environments with well-drained soil and limited pest pressure.

    There are recommended targets for percent grain moisture and grain temperature for winter grain bin storage.  Those recommended targets are listed in the following tables (Tables 1. and 2.).

    Author(s): Laura Lindsey

    Soybean pod shattering is not completely understood.  Through breeding efforts (beginning approximately 5,000 years ago when soybean was first thought to be domesticated), soybean plants have gained pod shattering resistance (Dong et al., 2014).  However, certain environmental conditions can lead to pod shattering.
