Overview

Proportion of plants emerged (a) and relative total dry biomass yield (b) of bioenergy sorghum and maize. The most severe waterlogging occurred near the wet end of the transect (left), while further distances remained well-drained (right).

In 2020, early-season extreme precipitation events occurred after the planting of Sorghum bicolor (L.) Moench and Zea mays L. in central Illinois that caused ponding. Following the first rainfall event, 50m transects were established to assess the waterlogging effects on seedling emergence and crop yields. Soil moisture, emergence, stem and tiller count, LAI, and yield were measured at various points in the season along these transects.
