When To Replant Sugarbeets: The Relationship Between Population, Yield, And Replant Timing January 8, 2018

An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics: Early season stand loss from wind or frost can be severe enough to require replanting of a sugarbeet crop. Three years of field trials at the Panhandle Research and Extension Center were conducted to determine just how much stands need to be reduced to justify replanting.

Protect Future Wheat Yields: Control the Volunteer Green Bridge August 2, 2017

Wheat streak mosaic virus (WSMV) problems have been extensive throughout the western Great Plains this year, significantly reducing the yield potential of many fields. A critical key in managing this threat in the next crop is elimination of volunteer wheat. Tillage or chemical weed control should occur at least one month before planting to allow host plants time to dry up and cease being a host.
