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.
Crop modelers wrap up their forecasts of rainfed and irrigated corn yields across the Corn Belt for 2017, noting above-average yields for about 80% of the irrigated sites and more than 60% of the rainfed sites. Irrigated yields ranged from 11%-17% over long-term averages at those sites and rainfed yields at those sites were 13%-40% above average. View data for all the sites.
Forecasts for end-of-season corn yields improved across much of the Corn Belt since the early August forecast. View crop stage and yield forecasts as well as weather data. In Nebraska predictions are for near to above average corn yields for most sites, except northeast and northwest sites.
The winter wheat varieties planted in eastern Nebraska today can yield upward of 140 bu/ac under good management and weather. If you haven't planted wheat in several years, consider today's advanced genetics and these other benefits from integrating wheat into your rotation.
