1. Can nitrogen application rate and timing management contribute to yield benefit in dryland winter wheat?Nitrogen (N) is a key component that affects grain yield and protein content in wheat. Optimizing fertilizer N application rate and time may contribute to an increased yield along with an adequate protein level. To evaluate the effects of different rates and application timing of N on grain yield and quality, a field study was carried out at four different locations across Nebraska (Mead, Grant, Sidney, and Scottsbluff) in 2018/19. At all locations, the experimental layout was split-plot randomized... D. Ghimire, B. Maharjan |
2. Improving Nitrogen Management in Dryland Winter Wheat Production in NebraskaWheat producers in Nebraska endured a significant loss in profit due to reduced grain protein in years that had wet springs such as in 2016 and 2017. Among many potential factors, soil nitrogen (N) is the most central factor that affects protein levels in wheat. To investigate the effect of N on wheat grain yield and protein content, field trials across the State were initiated in 2018. The specific objectives of the field study were to evaluate the effects of different N rates and application... |
3. Optimizing Nitrogen Management for Sustainable Production of Furrow-Irrigated Corn in Nebraska PanhandleLosses of nitrogen (N) via leaching to groundwater and greenhouse gas emissions pose an environmental and human health threat. The risk for environmental N losses, particularly nitrate leaching loss, is greater in furrow-irrigated fields than those under drip or sprinkler irrigation. Furrow irrigation accounts for 30% of total irrigated acres in Nebraska and approximately 36% in the US. However, much of the efforts for N management improvement are concentrated on sprinkler or drip systems. The... B. Maharjan, D. Ghimire |
