Researchers report their findings from a one-year cover crop study at two sites in western Nebraska to study the impact of planting and termination dates and cover crop species selection. This article is part of the Crop Production Clinic Proceedings 2019.
Farmers throughout the Corn Belt may want to consider diversifying traditional corn and soybean rotations to increase agronomic sustainability and to spread financial risks associated with low market prices of corn and soybean. An alternative is a more diverse crop rotation using field pea (short-season grain crop) followed by cover crops, forages, or short-season crops (Figure 1).
A research project in eastern Nebraska is evaluating a double crop production system as a potential alternative to the traditional corn/soybean rotation. Following an early season crop of yellow field peas, short-season crops (corn, soybean, grain sorghum, millet and sunflower) and annual forages (forage sorghum and sorghum-Sudangrass) were planted.
Managing weeds at least two weeks prior to planting winter wheat and then controlling winter annuals this fall are important to reducing disease, saving soil moisture, and achieving top yields next summer.
Sawfly management in wheat requires a diversified approach using a number of tools. Growers who know which fields have greater levels of infestation can help manage the effects of sawfly this year as well as next year. Fields with high infestations should be harvested first, if possible.
