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.

Cover Crop Forage Field Day Aug. 25 near Boelus

August 3, 2016

University of Nebraska-Lincoln Extension is hosting a Cover Crop Field Day Aug. 25 to focus on using cover crops to both improve the soil and produce forage. Lease agreements for cover crop grazing also will be addressed.

Aug. 20 Farm Tour to Look at Cover Crops, Flaming, and Crimping

August 1, 2016

A Butler County farm tour will look at two operations where growers have integrated cover crops and used flaming or crimper tecnology to manage weeds. The tour will be Saturday, August 20 from 1:30 p.m. to 5:30 p.m. and followed by a meal.

Wheat Stem Maggot Damaging Corn after Rye

June 9, 2016

UNL has been tracking an unusual insect pest the past couple of years in northeast Nebraska that may be a potential concern to farmers growing corn after rye or other grass cover crops. A number of producers and crop scouts have reported stunted corn plants at V1 to V2 with brown flagging in their fields due to the wheat stem maggot (WSM), a species of Chloropid fly. These are small flies that are typically about 1/8 inch long with black and yellow markings. The wheat stem maggot overwinters in the stem of its host plants as a larva and emerges in May to begin feeding.
