Nebraska soybean and corn yields have steadily increased from 1971 to 2017 in both irrigated and rainfed production systems. Nebraska irrigated soybean increased at a linear linear rate of 0.68 bu/ac, and irrigated corn increased at a rate of 2.17 bu/ac.
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.
Learn how to examine plant development and use this forensic strategy to determine the approximate calendar date when the plants in your field were likely exposed to dicamba.
There are now five structurally different growth regulator herbicides, each of which affects plant growth differently. Understanding the differences can help you better identify the cause when you find damage in your field.
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.
Averaged across two years, the sensor-based N fertigation treatment consistently resulted in higher profit and nitrogen use efficiency. The use of fertigation offers the unique capability to minimize N losses by reacting to slight N deficiencies in corn by applying N multiple times throughout the season with lower application rates.
