Nebraska Extension Pest of The Month: Horseweed
January 5, 2017
Horseweed (marestail, Conyza canadensis L.) is a unique weed species that can emerge in both fall and spring. In Nebraska, unlike the eastern Corn Belt, horseweed populations predominantly emerge in fall as a winter annual.
Finding the Balance Between Corn Yield and Cover Crop Biomass
November 29, 2016
Cover crops can provide either ecosystem services or forage benefits but understanding how they fit in cropping systems is still limited. This study assessed the effects of planting date (early and late), plant population (low, average, and high) and corn maturity (80 to 115 days relative maturity) on corn yield.
Fall is Optimal for Marestail Management
October 28, 2016
With corn and soybean harvest nearing completion in Nebraska this is a great time to begin scouting fields for winter annual weeds like marestail. Timing is critical to successful control of marestail, especially in no-till soybeans as many populations have evolved resistance to glyphosate and ALS-inhibiting herbicides.
Your Help Needed to Identify Palmer Amaranth Distribution in Nebraska

Nebraska Extension is requesting help in identifying the distribution of Palmer amaranth in Nebraska by taking this short survey.
Biomass Production of Winter Annual Cover Crops in Corn and Soybean
August 11, 2016
Rye was the leading biomass producer in the first two years of a four-year study exploring whether winter cover cropping in no-till corn and soybean systems in Nebraska can benefit soil quality despite their short growing season.
Herbicide Options for Planting Forage Cover Crops after Corn and Soybean
March 18, 2016
Cover crop adoption is continuing to increase throughout Nebraska. Respondents to the 2015 cover crop survey conducted during Nebraska extension meetings indicated the top five desired benefits from cover crops are
