Weed management is a long-term battle that needs to continue even in tight margin years.Although herbicide costs may seem prohibitive, it’s important to consider the long-term implications of limiting or eliminating the use of herbicides in crop production systems.Weeds left unmanaged after wheat harvest use valuable nutrients and water needed for the following year’s crop while producing seeds to replenish the soil seed bank.
By far, the greatest risk of losses from mite-vectored viruses occurs when there is a summer "green bridge" of volunteer wheat emerging before harvest. This almost always occurs as a result of wheat seed head shatter from hail storms (Figure 1).
Nebraska wheat growers can view and compare current and experimental wheat varieties and hear from researchers and specialists at six UNL Wheat Variety Trials to be held this June in west central Nebraska and the Panhandle. The June 15 tour at the Stumpf Wheat Research center at Grant will also include a field pea plot tour and presentations.
Although Nebraska’s planted wheat acres are at record lows, producers should expect high yields. Favorable growing conditions, including a mild winter and abundant precipitation, has Nebraska wheat positioned to achieve wheat yields not seen in the past five years. However, farmers should scout carefully for wheat rust and be prepared to treat any outbreaks in a timely manner.
Grain-type field pea is a spring-planted cool season crop that can be grown as an alternative for summer fallow in semiarid cereal-based, no-till cropping systems where wheat-corn-fallow and/or wheat-fallow are the main rotation strategies (Figure 1). Reasons for replacing summer fallow with field pea include:
