1. Does Nitrogen Management in Winter Wheat Affects Its Yield and Nitrate-N Leaching in a Wheat-Soybean Double Cropping System?Conventional corn (Zea mays L.)-soybean (Glycine max L.) rotation contributes to nitrate-N and phosphate leaching to waterbodies causing water quality concerns. Two strategies that could minimize N and P losses include (i) incorporating winter rye (Secale cereale L.) (WR) as a cover crop to capture residual nutrients or (ii) intensifying the corn-soybean rotation with winter wheat (WW) (Triticum aestivum L.) (Double cropping). Double cropping WW at a right N...

2. Short Term Effect of Double Cropping and Cover Cropping on Soil Physical PropertiesIntegrating cover crops into corn (Zea mays L.)-soybean (Glycine max L.) rotation has been promoted as a sustainable practice to reduce soil erosion, enhance soil health, and improve agricultural sustainability. However, growers are less inclined to include cover crops into their cash crop rotations especially winter cereals such as winter rye (Secale cereale L.) behind corn. One strategy to minimize the fallow period in corn-soybean rotation is by intensifying the corn-soybean... F. Sheikhi shahrivar, O. Ola, O. Guzel, K. Gage, K. Williard, J. Schoonover, S. Mueller, A.

3. The Effect of Nitrogen Management in Winter Wheat on Nitrous Oxide Emissions in a Wheat-Soybean Double Cropping SystemNitrogen fertilizer management plays a critical role in nitrous oxide (N₂O) emissions in agricultural production systems. This study investigated the impact of nitrogen application in a winter wheat (Triticum aestivum L.)-soybean (Glycine max L.) double cropping system on winter wheat biomass production, grain yield, and N₂O emissions. The experiment was conducted at the Agronomy Research Center (ARC), Carbondale in Southern Illinois University, IL using a Randomized Complete... O. Ola, O. Guzel, K. Gage, K. Williard, J.

4. Improving Corn Grain Yield and Reducing Nitrate-N Leaching with Urease and Nitrification InhibitorsSustainable corn (Zea mays L.) production requires proper nitrogen (N) management to optimize yield and minimize negative impacts of N losses on water quality. Nitrification inhibitors could be a viable strategy to synchronize N availability and corn N demand and decrease N loss through nitrate-N leaching. A field study was laid out in a randomized complete block design with five replicates at the Belleville Research Center (2023-24) and the Agronomy Research Center (2024-25), IL, with... S. Koduru, O.

5. Influence of Nitrogen Fertilization Frequency and Rate on Nitrous Oxide Emissions in Winter WheatManaging nitrogen (N) fertilizer effectively is important for reducing nitrous oxide (N2O) emissions in farming systems. This study examined the effect of N application frequency and rate on winter wheat (Triticum aestivum L.) grain yield, total N₂O emissions, and yield-scaled N₂O emissions. The experiment was conducted at the Agronomy Research Center (ARC), Southern Illinois University, Carbondale. A randomized complete block design (RCBD) was used with... O. Ola, O. Guzel, K. Gage, K.
