1. Intensive Nitrogen Management of Soft Red Winter WheatThe current system of making nitrogen recommendations for wheat in the Eastern cornbelt assumes that nitrogen fertilizer required is a simple function of yield potential. The higher the yield potential, the more N fertilizer needed. The problem with this assumption is that factors such as soil type and ability of a site to release N through mineralization, climate, variety. disease pressure and managetnent practices all affect nitrogen use efficiency, and are not considered in making nitrogen recommendations.... |
2. Should we incur a loss by interseeding in sugarbeet ?The Red River Valley of North Dakota and Minnesota contributes with half of the nation’s sugarbeet (Beta vulgaris L.) production. Interseeding cover crops within sugarbeet has the potential to reduce the impact of soil disturbances. Field experiments were conducted to evaluate the impact of cover crop interseeding time and species on sugarbeet root yield, sugar content, and economic profitability during 2018 -20 growing seasons. Cover crops were first interseeded in June and second... S. Sigdel, A. Chatterjee, M. Berti |
3. 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...
