Spring Wheat Research in Western Nebraska

August 13, 2020
Many farmers view spring wheat as a rotational crop with a purpose to break the weed and pest cycles, build up the residue cover and increase yield of corn the following years.

Seeding Practices and Nitrogen Management for Western Nebraska Soybean: What Matters and Why

March 30, 2020
Continuous corn is the most common irrigated crop sequence in southwest Nebraska. Although rotating to other crops, such as soybeans, can mitigate some production issues of continuous corn and often boost the next year’s corn yield, larger adoption of soybeans has not readily occurred in this area.

Should I Consider Spring Wheat in My Cropping System?

February 19, 2020
Beginning in the 1970’s winter wheat was included in Ecofarming rotations with no-till corn or grain sorghum and summer fallow as a means to capture and maintain soil water through snow retention, increased infiltration, reduced evaporation, and weed control with herbicides instead of tillage.

Soybean Fertility Study in Western NE: What is Limiting High Yield and Protein?

February 7, 2020
Public universities and private companies were contacted early in 2019 to provide input on the study protocol that would compare multiple fertility programs for soybeans in western NE. A total of 12 fertility programs were compared.

Seeding Recommendations for Irrigated Soybean and Dryland Corn in West-Central Nebraska

January 23, 2020
Continuous corn is the most common irrigated crop sequence in southwest Nebraska. Although rotating to other crops, such as soybeans, can mitigate some production issues of continuous corn and often boost the next year’s corn yield, larger adoption of soybean has not readily occurred in this area.

Main Factors Influencing Yellow Field Pea Protein Content in Nebraska

January 23, 2020
Yellow field peas (Pisum sativum L.) recently gained popularity across Nebraska due to their rotational benefits and increase in consumers' demand for plant-based alternatives to meat and dairy products.
