1. Post-Wheat Summer Cover Crop Effects Crop Yields and Soil Properties in a No-till Dryland Cropping SystemTraditional dryland cropping systems in the semi-arid Great Plains include long fallow periods of up to 14 months to conserve soil moisture. However, such systems are inefficient even under continuous no-till (NT) management. As less water is necessary to produce forage compared to grain, cover crops (CCs) may be successfully integrated into dryland crop rotations for increased soil cover and potentially greater income when hayed or grazed as annual forages. One study was initiated in 2016 near... L.M. Simon, A.K. Obour, J.D. Holman, M.E. Schipanski, S.K. Johnson, K.L. Roozeboom |
2. Snapshot of Crop Nutrient Balance with Use of a Rye Cover Crop in a Corn-soybean Rotation Under Tile Drainage in Eastern South DakotaThe purpose of this study was to evaluate the effect of using a winter rye cover crop within a corn/soybean rotation (rye seeded every fall and burned down each spring) on drainage water quality, crop nutrient status, and grain yield. Use of a winter rye cover crop to take up available N from the soil profile is a management tool that may help to lessen nutrient movement out of the soil profile while at the same time contributing to improved soil health. Winter rye is very winter hardy... P. Sexton, S. Kumar, S. Osborne, B. Brockmueller, A. Bly, B. Rops, A. Bawa, S. Bauder, J. Mcmaine |
3. Effects of Climate Change and Narrow Rows with Higher Plant Densities on Yields of Irrigated CornClimate change is significantly impacting agricultural systems worldwide, and although there are reports of these impacts contributing to higher yields in some regions, the general consensus is that there will be negative impacts on yields and soil quality across large regions. Management practices that can contribute to higher yields and adaptation to a changing climate will be important during the 21st century. This presentation will cover results from two manuscripts that are currently... J.A. Delgado, B. Floyd, R. D'adamo, A. Villacis, A.D. Brandt, A. Halvorson, C.E. Stewart, J. Alwang, S. Del grosso, D.K. Manter |
4. Combined Nitrogen with Magnesium or Zinc Effects on Sugarbeet Yield Sucrose Concentration, and Nutrient Uptake Under Conventional and No-till SystemsSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River valley. Fertility, especially nitrogen (N) fertilizer, management is critical for sugar beet yield and sucrose concentration. While farmers are switching from a conventional tillage method to a no-till system for sugar beet cultivation, nitrogen (N) fertilizer application timing might need to be adjusted. Furthermore, micronutrients may enhance sugar beet yield and sucrose concentration. A two-year... C. Chen, M. Etesami, M. Abdelhamid |
5. Assessing Corn Response to Cover Crops and Nitrogen Fertilization in a No –Till, Three-year Rotation in Northeast KansasAs industry initiatives and government programs begin funding and incentivizing climate-smart agricultural practices, more farmers in the great plains region may be interested in incorporating cover crops into their rotations. Annual yield data can aid in understanding how cover crops impact cash crop productivity in this region. A long-term cover crop experiment in northeast Kansas was established in 2007 based on a wheat – corn – soybean rotation to determinate the... A. Correira, J. Grunberg, P. Tomlinson, K. Roozeboom, D. Presley |
6. Influence of Irrigation Timing and Amount on Cotton Physiology and Nutrient PartitioningThis study explores the impact of varying water levels on nutrient uptake in cotton plants, known for its sensitivity to environmental conditions. Recognizing the pivotal role of water availability in agricultural productivity, the experiment employed different irrigation scenarios and assessed the efficiency of nutrient absorption in cotton under these varied circumstances. The research also focused on analyzing nutrient content in different plant tissues,... K. Vargas, K. Lewis, J. Bicaldo, J. Burke |
