Field pea

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.

Help Us Identify Yield-Limiting Factors in Nebraska Soybean Fields October 5, 2016

Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.

Sprinkler Irrigation System Maintenance for Improved Uniformity and Application Efficiency August 23, 2016

Center pivot irrigation systems are designed and managed to apply water as uniformly as possible to enhance crop production. Uniformity has a direct effect on the system’s overall application efficiency, which is a measure of how well an irrigation system delivers water to a crop’s root zone.

Irrigation Sensor Installation Tips May 26, 2016

As planting progresses across the state, it is recommended that irrigators start installing water sensors in fields as time allows. Any time sensors are installed, a few simple questions should be addressed to ensure accurate readings for irrigation management later this season.

1)  When should sensors be installed?
