Field Pea and Chickpea Germination and Yield as Affected by Tillage

October 17, 2019
Research conducted with field peas and chickpeas near Grant found that yield increased slightly with the use of tillage; however, tillage was not recommended for dryland and semi-arid conditions.

Optimum Planting Times to Establish Cover Crops Following Corn

September 16, 2019
Results from a UNL study assessing biomass production of two cover crops (cereal rye alone or a cereal rye mix) planted either pre-corn harvest or post-corn harvest at three sites in eastern Nebraska.

Management Decisions Impact Wheat Stem Sawfly Populations

August 30, 2019
University research in the Nebraska Panhandle suggests that changing two management strategies may help significantly reduce wheat stem sawfly pressure in winter wheat. Over the years, the sawfly has become a major pest in wheat with few known control measures.

Nebraska Team Merges Machine Learning, Plant Genetics to Maximize Sorghum Potential

August 22, 2019
Sorghum is emerging as a star player in the biofuels industry. With its water use efficiency, resistance to heat, and low cost of seed, it could outpace corn, with a little boost from improved genetics. To aid that, a UNL team was recently awarded a $2.7 million grant to work on a rapid, efficient method for characterizing its gene functions.

Gap Growing Between Irrigated, Rainfed Crop Yields

August 13, 2019
A 65-year comparative analysis between U.S. yields of irrigated and rainfed crops has sounded a message to farmers, land managers and policymakers: Mind the gap. Researchers analyzed annual yields of nine crops on a county-by-county basis from 1950 to 2015.

New Stalk Sensor Could Lead to Improved Drought-Resisistant Corn

July 31, 2019
Researchers at the University of Nebraska and Iowa State University are pursuing an elusive goal: measuring rates of sap flow in corn in real-time, actual fields, and changing weather conditions. Their data on corn water use could lead to improved drought resistance.

Figure 1. Research in northeast Nebraska indicates that adding alfalfa to a corn-soybean rotation can reduce nitrate in the aquifer while increasing profit.

Adding Alfalfa to Corn-Soybean Rotation can Increase Profit, Reduce Nitrate Leaching

July 31, 2019
University research shows that adding alfalfa into corn-soybean rotations can help reduce the loss of nitrate to and increase the extraction of nitrate from aquifers while improving profitability.
