Development of an integrated weed management (IWM) package to mitigate glyphosate-resistant weeds in soybean

All of the experiments will focus on the performance of soybean in weedy and weed-free conditions. This will aid in our understanding of how weeds impact soybean yield loss and how soybean agronomy may be optimized to mitigate yield loss and also reduce weed seed production. One experiment will assess the impacts of crop sequencing, residue management, and soybean planting date. Another will assess soybean growth habit, maturity grouping and planting date. A third experiment will assess the impacts of fall rye cover cropping, soybean growth habit, row spacing, and seeding rate, while a fourth experiment will determine the optimal soybean row spacing and seeding rate based on soybean growth habit (bushy vs. erect).
