Project Summary

Drought stress is a problem in most soybean fields in SC every year. There is not a year that goes by that heat and a dry spell doesn’t cost yield in SC fields. It is hard to find any drought stress data on soybean varieties. In the seed guides that all seed companies produce, corn will always have data showing drought tolerance of their hybrids, but never is the same data for soybean varieties available, so this data should be relevant to SC growers. This trial, located in the heart of the Sandhills region of the state, at the Sandhill REC, will surely give good drought stress ratings for this trial.

This drought stress trial will be in the heart of the Sandhills region of the state, at the Sandhill Research and Education Center, will surely give good drought stress for the trial. Varieties that will be entered into the Soybean Official Variety Trial will be entered into this trial, so varieties in MG 5-8’s will be evaluated for their ability to overcome drought conditions, so often observed in the summer in SC. Like the OVT program, this trial will be in replicated small plots, replicated 4 times, taken out to yield but ratings will be taken during drought stress events. The drought tolerance of these varieties may come from simply a nematode package that a particular variety may have, or it may come from the growth habit or even the plant type that can help under stressful conditions. The intent is to give growers information that will lend him a better option when planting soybeans to some of the sandy soil types on his farm, so that hopefully better yields can be made when weather conditions are at their most disruptive to SC agriculture.

Project Objectives

Project Deliverables

Current progress will be given with the first two quarterly reports. Updates will be given and shown at the Field Days at each Station. Finally, results will be given with the last two quarterly reports as well as at county production meetings. Social media can also serve as a good way to list results of the trial.

No data will be taken from this trial as the drought and lesser cornstalk borer really destroyed it. Weeds and insects have been sprayed so all that is left is some final evaluations and harvest.
Only thing to do is look forward to a new trial in 2020.

Performance Metrics

Key indicators will be if some dry spells take place this summer at the Sandhill REC and we see differences in response to the weather as well as the differences in yields in the end. Final statistics will give us a better idea of whether the trial was a success or not. And then hopefully popular varieties will show some success and growers can use not only the yield results of OVTs as well as company trials and other results that they may use, but also the data that this trial will create.
