Subsoiling is an important management practice for improving maize yield, especially for maize planted at high plant density. However, the affected physiological processes have yet to be specifically identified. In this study, field experiments with two soil tillage (CK: no-tillage, SS: subsoiling) and three planting densities (low: 45000 plants ha-1, medium: 67500plants ha-1, and high: 90000 p...
Seedbed conditions during corn (Zea mays L.) planting can have substantial impact on stand establishment and final yield. Planting management decisions are complex due to spatial variability caused by changing soil characteristics such as texture or landscape position. Field experiments conducted in central Missouri from 2017 2019 assessed the effects of varying depths Sites included fine- coar...
1 We used a combination of laboratory and field experiments to test the hypothesis that the burial depth of Potamogeton pectinatus tubers will vary with local sediment type and swan predation pressure. 2 In the field, mortality due to predation by swans decreased linearly with burial depth (from 100% at the surface to 55% at 225 mm depth) and with sediment clay content. Average tuber size showe...
