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. 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 |
3. Shining Light on Novel Pathways for Potassium Fixation in SoilCotton has a high demand for potassium, and potassium significantly affects both cotton yield and fiber quality. Thus, bioavailability of potassium from the soil is paramount. Bioavailability and leaching of potassium to crops and from soils has been studied since the 1940s. However, problems that confronted agronomists in the 1980s continue to impact growers and crop production, including unpredictable potassium bioavailability and inconsistent plant response to fertilizer application under a...
