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).
Results of research conducted since 2000 to address fertilizer phosphorus (P) for corn will be reviewed. The current fertilizer P recommendations for corn will be discussed and revised recommendations presented at the 2019 Crop Production Clinics.
Do early season weeds have the same impact as later season flushes? Researchers here report on a 2018 study conducted in dry bean to compare how soon after planting crop yield was impacted by weed presence.
Understanding the critical time for weed removal in corn and soybean would not only ensure effective weed removal and minimize unnecessary weed control inputs, but could potentially help minimize the development of herbicide resistance in weeds.
Today’s agricultural researchers are turning to plant genomics to find solutions for growing crops more sustainably with fewer inputs, including nitrogen fertilizer, without sacrificing yield or profit.
While diseases are one of the three biggest yield-limiting factors of sunflower production, there was little information on how to identify and manage them until university plant pathologists joined in a collaborative effort to conduct research and develop educational resources.
