Corn yield forecasts and crop growth stage estimates for the US Corn Belt, based on crop modeling and local input, start up this week for 2018. Corn development is well ahead of normal, with most sites in the central and southern fringes of the Corn Belt in the silking or grain-filling stages.
Here's how the Yield Forecasting Center will be developing corn yield forecasts for 41 locations across the Corn Belt during the 2018 crop season. Modeling, using Hybrid-Maize, weather data, and on-site verification help researchers estimate yields so growers can adjust management during the season, if necessary.
While continuous corn is the most common cropping sequence in southwest Nebraska, adding soybeans to a rotation could help break pest cycles. On-farm research comparing 15- and 30-inch soybean row spacing found increased yields of 4-12 bu/ac with an average 7 bu/ac increase with 15-inch rows.
University researchers report results from studies conducted on herbicide tolerance trait, row spacing (15-inch vs. 30-inch), and soybean maturities (early vs. late) at three locations of the Soybean Management Field Days in summer 2017.
Cover crops offer many benefits, such as improved soil heath and reduced erosion. The challenges lie in the details, including what cover crops to use and how to use them. The Feb. 15 Nebraska Cover Crop Conference tackles these topics for growers using a corn/soybean rotation.
