Drought and Heat Effects on Corn Production

Nearly every season in South Dakota there are periods of hot, dry weather in at least parts of the state. While we have no control over the weather, producers can prepare for drought stress by using proactive practices.

Estimating Corn Emergence With Growing Degree Days: Data from May 7, 2021

With corn planting well underway in South Dakota, the next step is monitoring its emergence. One of the factors that can speed up or delay corn emergence is air temperature.

Low Temperature Damage to Corn and Soybean

Temperatures are forecast to reach 32°F or lower in large areas of South Dakota for several nights beginning on May 7, 2020. While a relatively low percentage of planted crops are likely to be emerged at this point in time, producers may still want to evaluate individual fields for crop damage.

2019 Corn Growing Degree Day Update

Growth and development in crops are a direct response to accumulated heat units or growing degree days (GDD). The Corn GDD Tool at the High Plains Regional Climate Center can be a useful resource for not only estimating crop growth stage, but also for selecting hybrids within the appropriate maturity group.

Are My Crops Susceptible to Chilling Injury?

To say that the spring of 2019 has been a challenge for South Dakota producers is an understatement. According to the USDA-NASS, corn and soybean planting progress in SD was pegged at 19% and 4% on May 20th, respectively, which is far below the 5-year averages of 76% and 39%. Last week was the first time much of either crop was planted in SD.
