Most yellow field pea being grown in western Nebraska were at early vegetative stages (4th to 7th node or 1-5 leaf stages) during last week’s cold snap, but extensive damage is not expected due to the pea’s level of frost tolerance.Field pea tolerance to frost during early stages of vegetative growth is partially due to the “hypogeal” germination nature of the crop. For plant species with hypogeal germination (e.g., field pea, lentil, chickpea), shoot germination occurs belowground.
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.
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.
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.
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.
