Battle for the Belt: Episode 25

Episode 25 of Battle for the Belt is now available:

In Episode 25, we walk through the Farm Science Review agronomic crops plots with Madison County and Champaign County Extension Educators, Amanda Douridas and Grant Davis.

The Agronomic Crops Team is at the Farm Science Review (FSR) every year showcasing demonstration plots that are representative of the research questions being evaluated across the state. These research projects can be from eFields, on-farm research, or small plot research done at the University. This year, there are 17 crop plots demonstrations at FSR Ag Crops Team, some of which include Xyway, Pivot Bio, Nitrogen Rates, Soybeans Disease, Biostimulants, and Battle for the Belt.

Tickets for FSR are sold at local county extension offices, online (here), and at the gate of the FSR. If you are a student (or affiliated at Ohio State) with a BuckeyeID, admission should be free. The dates this year are September 19-21, at the Molly Caren Agricultural Center 135 Ohio 38 NE London, OH 43140. For more information about the review, visit us at


Battle For the Belt Location Updates


Figure 1. Planting date one at the Wooster location, flooding conditions, left side.

The Wooster location received heavy rains like Western and Northwest this last week, leaving some plots with flooding conditions (Figure 1). The soybeans at this location are all at R5. The R5 stage is the reproductive stage that soybeans will stay in for weeks. R5 begins when one pod on one of the four uppermost nodes has seeds that are 1/8 inch long and ends when one pod on one of the uppermost four nodes has a seed that is fully developed. The soybeans at this location had a poor stand which made the existing plants compensate (at least partially) in the open spaces (e.g., more branching). Few hybrids at the early planting dates have reached dent stage (R5). Planting date five at this location finally reached R1 (silking stage).

*The Wooster location weather was not available for the end of the month, so it is not reflected in Table 1.

At the Western location planting date one and two are completely at R5 stage (dent). At R5 we are conducting disease assessments to track disease progression throughout the season. The 100-day hybrid has had the most disease severity in both planting dates, however most hybrids have between 5% and 10% severity for Gray Leaf Spot as well. At this location, bouquet ears have been observed (Figure 2). Bouquet ears are considered an abnormal ear symptom. These have more than one ear (2 or more) ears on a single ear shank. Later this season, abnormal ear assessments will be conducted to evaluate if planting date or hybrid effects are present. Another anomaly observed at this site is lodging (aka goosenecking) after high-speed winds several days ago. On the other hand, soybeans are close to being full pod (R4) in planting date one and five in soybeans. At this site, planting date five just reached beginning seed stage (R5).

The Northwest location has some of the largest ears we have found at the three locations, though this location still has a long way to go before reaching full maturity. The soybeans at this location have more grasshoppers than other locations but the insect damage severity is not generally more than 5%.
