1. Tillage and Nitrogen Management for Irrigated Sugarbeet Production in Eastern MontanaSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River region. Nitrogen management is very critical while farmers are transitioning sugar beet production from conventional tillage to no-till system. The objectives of this study were to: (i) evaluate the effects of fertilizer-N rate and application timing on sugar beet root yield, sugar content, and quality under conventional and no-till managements, (ii) determine N uptake and N use efficiency (NUE)...

2. Forgiven Not Forgotten: a Short History of Wind Erosion on the Canadian PrairiesSince agriculture arrived on the Canadian prairies in the late 1800s, wind erosion has always been a constant threat. The 1930s saw some of the worst wind erosion but spurred the invention and adoption of soil management techniques to provide better crop residue management, the number one line of defense against wind erosion. The conservation tillage movement of the 1990s saw increased no-till and summer-fallow almost disappeared. However, recent trends of more intensive tillage on the Canadian... F. Larney |
3. Adjusting N Rate is the First Step in N Management IntensificationNitrogen (N) management and sowing date are among the leading causes for winter wheat (Triticum aestivum L.) yield gap in Kansas. This research aimed to compare the two most common cropping sequences in Kansas (continuous wheat [Ct-Wt] and double-cropping of winter wheat and soybean (Glycine max (L.) Merrill) [Wt-Sy]) under two N management (standard and progressive) on wheat production. Standard N management consisted of one single broadcast N application as UAN at 80 lbs ac-1 at... L. Simao, R.
