1. Nitrogen Managememt in Dryland Winter Wheat to Improve Grain Yield and ProteinMaximizing the yield along with adequate protein content in winter wheat is an emerging challenge for dryland wheat producers. Proper nitrogen (N) management with optimization of fertilizer application rate and timing might be a potential strategy to improve grain yield and protein. The objective of the study was to evaluate the effects of different N rates and application timing on grain yield and protein content of hard red winter wheat in Nebraska. Field study was carried out at four locations... D. Ghimire, B. Maharjan |
2. 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 |
3. Sugarbeet Yield Response and Nitrate Leaching As Influenced by Nitrogen Management in Semi-arid ClimateFertilizer nitrogen (N) in irrigated sugarbeet production needs to be optimized to simultaneously increase yield and reduce nitrate leaching. In addition to adjusting N rate and application timing, there are available fertilizer technologies such as controlled- or slow-release N which may be beneficial for beet yield and reducing potential nitrate leaching. However, there are limited studies assessing the effectiveness of such fertilizers for sugarbeet in a semi-arid climate. The two-year experiment... D. Ghimire, B. Maharjan |
4. Dual-purpose Cover Crop and Occasional Tillage Effects on Crop Yields and Soil Properties in a No-tillage Wheat-sorghum-fallow RotationReplacing fallow with dual-purpose cover crops (CCs) could enhance soil health and increase cropping system profitability when CCs are grazed or hayed. Grazing and/or haying CCs can provide an economic benefit to offset potential lost revenue when grain crop yields are decreased after CCs in dry years. However, producers are concerned about the potential for root-limiting soil compaction following grazing on no-till (NT) fields, which could limit subsequent grain crop yields and require tillage...
