Field Pea Seeding Rates, Seeding Depth, and Inoculant

March 13, 2017
Grain-type field peas are a cool season grain crop grown as an alternative for no-till summer fallow in a semiarid cereal-based cropping systems such as wheat-corn-fallow and/or wheat-fallow. They are typically planted in mid-March and harvested late-July. This article reports on research conducted on seeding practices and offers recommendations for producers on the economically optimal seeding rate, seeding depth, and inoculant to grow field peas in western Nebraska.

Field Pea Production: Rotational Costs and Benefits

March 10, 2017
Research findings show benefits in soil nutrient cycling, water infiltration, and microbial activity from replacing fallow with grain-type field peas in a wheat-fallow rotation in western Nebraska.

Take Advantage of Warm Weather this Winter to Control Downy Brome

February 20, 2017
Just a month after double-digit below zero temperatures, Nebraska hit an extended period of above normal temperatures, coaxing weed seeds to germinate early in many fields and pastures and creating the need to tackle the influx early.

Growers Urged to Keep a Watchful Eye for Wheat Viruses This Spring

January 25, 2017
While the mild fall promoted wheat establishment, it also favored survival of wheat curl mites, the leading vector of several viruses common to Nebraska wheat. While much of the state's wheat crop entered winter in very good condition, growers are urged to scout for viruses this spring and assess yield potential of individual fields when making management decisions.

Nebraska 2016 Wheat – High Yields, Low Protein

September 1, 2016
Environmental conditions, management, and genetic differences played a role in why protein content in the 2016 wheat crop was lower than normal. Wheat protein develops as the plant converts nitrogen from the soil into amino acids. See what conditions led to low protein this season and how to address it for next year's crop.

The Value of Wheat in a Crop Rotation

August 31, 2016
Wheat is an important part of many crop rotations, adding value directly and often indirectly by aiding in soil water management and weed suppression, reducing erosion, and helping manage pest cycles. Consider wheat's value to your crop production system by looking at what it contributes over multiple years of the rotation.

Fall Weed Control Options for Winter Wheat

August 31, 2016
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.
