Description

Row crop production in the United States are geographically extensive and have large socioeconomic importance. Tillage, nutrient management, and cover crops practices effect runoff, infiltration, soil quality, and crop yield. This short term observational study was conducted to investigate the effect of four different agronomic practices on yield of Zea mays L (Maize) in southwest Wisconsin. Agronomic Practices consisted of: No till transition, autumn dry bedded pack manure application as a cover crop, no till; Conventional terrace system, narrow based terraces, autumn incorporated liquid manure, no cover crop; High density dairy manure, autumn incorporated liquid manure, and cover crop; Phosphorus reduction strategy, no manure, fertilizer applied as required, and cover crop. Leaf gas exchange, and plant mass, along with various soil parameters were measured along two transects within each treatment at harvest. Leaf level gas exchange was higher in the no till transition treatment when compared to the other agronomic practices. However plant dry mass was not effected by basin agronomic practice.
