Drought stressed soybeans
The importance of estimating soybean yield prior to harvesting as forage is illustrated in this photo of drought-stressed soybean from Washington County, NE. With a closer look at these plants, you can see 10 to 12 pods per stem with 3 seeds per pod on a few of the plants. These soybeans are not stressed enough to consider for hay or silage.
