I am continuing a second year of a State‐Wide Project aimed at generating some baseline producer data on current soybean management practices in Ohio’s production systems. This project is funded by the Ohio Soybean Council and the North Central Soybean Research Program (NCSRP). The project goal is to identify the key factors that preclude the State’s Soybean Producers from obtaining yields that should be potentially possible on their respective individual farms.

Last week, we received a few comments about soybeans having mature pods, but the stems remaining green. Similar observations were made in 2012…another dry year. Green stems on soybean may be a result of a source/sink problem. With the hot and dry conditions this year, pod set was likely reduced. With a limited number of pods (sink), there are fewer places for the plant’s photosynthates (source) to go.

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.

The purpose of the Ohio Soybean Performance Trials is to evaluate soybean varieties for yield and other agronomic characteristics. This evaluation gives soybean producers comparative information for selecting the best varieties for their unique production systems.

The American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America held its annual International Meeting last week in Long Beach, California. More than 4,000 scientists, porfessionals, educators, and students attend the meetings. Four Ohio State Horticulture and Crop Science graduate students won awards at the meeting.

Results of the 2014 wheat performance evaluation are available at: http://www.oardc.ohio-state.edu/wheattrials/. Currently, report text is unavailable. However, tables with yield and agronomic characteristics are available online.

On July 27, Hardin County experienced hail that damaged soybean at the R3 growth stage (beginning pod). The R1 (beginning bloom) to R5 (beginning seed fill) stages are the most sensitive to defoliation. At 50% defoliation when soybeans are at the R3 growth stage, we expect a 9-18% reduction in yield.

The first generation of the RoundUp Ready® (RR1) soybean trait patent is set to expire in 2015. This means that farmers can save seed with the RR1 trait for replant in spring 2015 if there are no other patents on the seed. Farmers will need to check with their seed supplier before replanting saved seed. Soybean seed can have both trait (i.e., RR1) and variety patents. Although, the RR1 trait patent is set to expire, there may be other trait patents and/or variety patents that prohibit replanting saved seed. If a farmer is legally able to save and replan

With wheat harvest underway, we often get questions about the nutrient value of straw. The nutrient value of wheat straw is influenced by several factors including weather, variety, and cultural practices. Thus, the most accurate values require sending a sample of the straw to an analytical laboratory. However, “book values” can be used to estimate the nutrient values of wheat straw.

As soybean planting wraps up, it’s time to consider evaluating soybean stands. Planting conditions were not always ideal this year. Soil conditions were a little wet when planting started and now have turned fairly dry in most areas. Here are some points to keep in mind when evaluating soybean stand.
