Impact of Cover Crop Management on Rainfed Corn Production in Western Nebraska January 9, 2019

Researchers report their findings from a one-year cover crop study at two sites in western Nebraska to study the impact of planting and termination dates and cover crop species selection. This article is part of the Crop Production Clinic Proceedings 2019.

Profit and Nitrogen Use Efficiency Gain Using Sensor-Guided Fertigation January 9, 2019

A UNL study of sensor-based and model-informed fertigation treatments confirms that sensor fertigation treatments are consistently the most profitable and efficient methods of applying N compared to current best management practices (BMPs).

Weather Ready Farms: Irrigation Water Management March 21, 2018

Climate variability, including extended periods of dry conditions and sometimes drought, are common on the Great Plains. When managing under these extreme conditions, irrigators need to understand daily and seasonal crop water use patterns and adopt practices and technology that result in more bushels of grain per inch of water applied.

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.
