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.
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.
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.
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
