Abstract

Flooding is a major obstacle for soybean production in the Mississippi Delta. One management practice that soybean producers use to mitigate the effects of flooding is planting soybean on raised beds. Another potential management practice that could be employed in the Mississippi Delta is the use of flood tolerant soybean cultivars. Therefore, the objective of this study was to evaluate the effectiveness of raised beds for flooding management and compare the tolerance of six soybean cultivars under flooded conditions at multiple growth stages and flood durations. Field studies were established during the 2017 and 2018 growing seasons at the Mississippi State Delta Research and Extension Center on a Sharkey clay soil. Treatments consisted of a factorial arrangement of six soybean cultivars, two flood timings (V4 and R2) and two flood durations (24 and 72 hours). Injury ratings were taken 7 DAT and 14 DAT. Seed yield was determined at harvest.
