Across Nebraska, the use of cover crops is increasing. Most commonly, winter cover crops are planted during the fallow period between corn or soybean harvest and the next crop. However, other windows for cover cropping exist in Nebraska.
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).
The end-of-season corn yield report finds that high temperatures during vegetative stages had little impact on forecasted yield potential. This is the final article in the series looking at simulated crop stages and yield forecasts for 41 locations across the US Corn Belt.
Corn progress and yield forecasts for 41 sites across the Corn Belt indicate near- or above-average yields for most sites. High temperatures early in the season increased the rate of corn development and led to a shorter crop cycle, but do not appear to have diminished yields.
Corn growth simulations across the Corn Belt indicate early corn maturity of one to two weeks for most sites. Simulated corn yields for rainfed and irrigated sites across the region near or above normal at most sites.
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.
