Control of Velvetleaf with Post-emergence Herbicides in Popcorn
August 12, 2021
Results of a study evaluating the efficacy and crop safety of labeled post-emergence herbicides to control velvetleaf, a major agricultural weed in Nebraska that reduces yields in popcorn if not controlled.
Weed Control and Response of Yellow and White Popcorn Hybrids to Herbicides
September 25, 2019
Research-based information on weed control and response of eight commercially available popcorn hybrids to several herbicides labeled for popcorn in Nebraska.
Pre-emergence Herbicide Delays the Critical Time of Weed Removal in Nebraska Popcorn
September 9, 2019
Understanding the critical time of weed removal (CTWR) and how a pre-emergence herbicide application can shift it is helpful for designing the most efficient weed management program in popcorn.
Soil Water Content- and Soil Matric Potential-Based Irrigation Trigger Values for Different Soil Types
July 11, 2019
Keeping a close eye on soil water content in individual fields can help optimize irrigation efficiency. This article explores how to use research-based trigger points for various soil types using soil water content-based sensors or soil matric potential-based sensors. Nebraska research has shown that having 25% more water than needed in the maize root-zone reduced grain yields as much as 15 bu/ac.
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).
Consequences of Fall-Applied N
November 9, 2018
A fall nitrogen application has a relatively high loss potential and is considered the riskiest N management practice. Consider breaking tradition and splitting your N applications next year to coincide with when your corn most needs more N.
Take Time to Set Up Nebraska Ag Water Management Equipment
May 23, 2018
As you finish planting, consider installing ETgages and soil moisture sensors before crop roots interfere. Then join the hundreds of farmers contributing their data each week to the Nebraska Agricultural Water Management Network, a valuable tool for managing your crop.
Feasibility of Sensor-Based Nitrogen Fertigation Management in Corn
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on university research testing sensor-based N fertigation treatments.
