Pre-harvest and harvest loss of grain can result in significant yield reductions. Pre-harvest pod shatter (breaking of pods resulting in soybeans on the ground) can occur when dry pods are re-wetted. This year, in our trials, we’ve seen very little pre-harvest loss.
To estimate soybean yield, four yield components need to be considered: plants per acre, pods per plant, seeds per pod, and seeds per pound (seed size). A printable worksheet to estimate soybean yield can be found by clicking here.
The results of the 2016 Ohio Soybean Performance Trials are now available online at: http://www.oardc.ohio-state.edu/soy2016/. The online results includes sortable tables, soybean physical characteristics (plant height and seed size), and seed quality (protein, oil, and fiber).
