How Important is Timing of Tassel Applications on Corn?
As the Mississippi corn crop approaches tassel, crop health and weather may greatly affect crop response to various management inputs, including nitrogen fertilizer or other products. This article will discuss factors that may affect your strategy and improve your response.
Video – How to Identify Corn Vegetative Growth Stages
This video shows how to identify vegetative growth stages of corn or sorghum in the field. In this case we inspect two different examples of corn that have progressed into rapid growth stages.
How to Determine Corn Vegetative Growth Stages
Vegetative growth stages of corn are determined by counting the number of fully emerged leaves with leaf collars present. It is important to appreciate this methodology since it is a basis for timing many management practices, including herbicide application, sidedress fertilizer, and others.
Improving Corn Response to Nitrogen Fertilizer
Nitrogen is a hot topic for corn growers due to extraordinary fertilizer prices. Fortunately, there are methods we can employ to improve nitrogen efficiency. This article gives recommendations to improve corn response to nitrogen fertilizer and reduce risk in our Midsouth environment.
When is the Cut-Off Date for Planting Corn?
As rains delay corn planting progress across much of the state, you may be wondering how to proceed with crop planting intentions. This newsletter helps address that question by explaining how corn responds to late planting when grown in different production systems based upon research conducted by Mississippi State University.
Early Corn Planting and Issues with Cold Temperatures
Cold and freezing temperatures are making a rare impact on early corn planting this year. Thus, we discuss how corn previously planted may be affected, as well as how you can assess planting conditions before proceeding with future planting in this edition of the Crop Doctor’s Podcast.
County Meeting Schedule – January 2022
Mississippi State University Extension will be hosting several county row crop meetings this month. Each meeting will cover issues specific to the region including management topics on agronomics, insects, weeds, diseases, and economics. A meal will be provided at each
2021 MSU Corn Hybrid Demonstration Program Results
Mississippi State goes to great lengths to evaluate, assess and analyze corn hybrid performance, so you have good information to make decisions which improve the profitability of your farm. These Hybrid Demonstration trials are grown in numerous on-farm locations throughout the state where you can better evaluate hybrid performance of our region’s most elite hybrids. Full results, including yields and plant characteristics from this year’s trials are published here.
2021 MSU Corn Hybrid Trial Disease Evaluations – Irrigated Locations
Irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2021 season. Curvularia leaf spot and southern rust were the two most commonly observed diseases. Little if any northern corn leaf blight (NCLB) was observed; however, where observed the evaluations were captured and are contained in the associated tables from each location. Presently, the evaluations from the irrigated locations (n=5) are included in the current post.
2021 MSU Corn Hybrid Trial Disease Evaluations – Non-irrigated Locations
Non-irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2021 season. Curvularia leaf spot and southern rust were the two most commonly observed diseases. Little if any northern corn leaf blight (NCLB) was observed; however, where observed the evaluations were captured and are contained in the associated tables from each location. Presently, the evaluations from the non-irrigated locations (n=5) are included in the current post.
The Topic of the Times: Fertilizer Prices and What to Do
The fire-starter for 2022 crop input discussions is fertilizer prices. Without getting into the why for the current volatility, first recall this situation is not entirely unique. Potash at the farmgate was about 14 cents per pound for years, if
What to Look at in a Corn Hybrid Evaluation? (Podcast)
Erick Larson calls into the Crop Doctors’ Podcast studio in Stoneville to talk about selecting corn hybrids for 2022. Erick, Tom, and Jason talk about similarities and differences between small- and large-plot hybrid performance trials, important parameters to use to
2022 MSU Short List of Suggested Corn Hybrids
This publication lists those corn hybrids which have demonstrated superior performance in the Mississippi Corn for Grain Hybrid Trials. No other source tests as many hybrids representing today’s market. Thus, this is a great starting point and barometer for you to judge hybrid performance and select the best corn hybrids for your farm.
2021 Yield Summaries from the MSU Corn Hybrid Demonstration Program
Mississippi State goes to great lengths to evaluate, assess and analyze corn hybrid performance. These Corn Hybrid Demonstration trials are grown in numerous on-farm locations throughout the state where you can better evaluate hybrid performance of our region’s most elite hybrids. Preliminary grain yield results from this year’s trials are published here.
Burning Stalks – What does it Really Cost?
Despite all the focus on improving soil health, it may be easy to overlook the impact that crop residue management has on soils and future productivity. The residue generated in crop production systems can produce substantial benefits. This article discusses issues associated with burning crop residue.
2021 Row Crop Short Course
Plans are currently being made to hold the 2021 Row Crop Short Course face to face at The Mill Conference Center in Starkville, MS. We are closely monitoring the pandemic as well as local health and safety guidelines and are
Corn Grain Drydown and Strategies for Successful Harvest
Corn harvest should ramp up soon as grain matures and dries down to an agreeable moisture for harvest. Understanding how weather and other factors affect grain drying, potential harvest losses, moisture dockage and storage issues can greatly help improve your harvest efficiency and success.
How to Estimate Corn Yield Prior to Harvest
Would you like to estimate your corn yield prior to the combine heading to the field? If you are willing to put in a little time, you can make a rough estimate by following these guidelines. While any such method leaves considerable opportunity for error, this process will likely be a good opportunity to learn more about your corn crop.
When to Terminate Irrigation in Corn
As the corn crop nears maturity, knowing when you can safely terminate irrigation, without sacrificing yield, or wasting money and labor through unnecessary irrigation is likely the most important decision that will affect your bottom line. This article outlines the steps needed to help make these decisions accurately and reliable.
