Identifying Corn Reproductive Stages and Management Implications
Corn progresses through six stages as ears develop through reproductive growth stages. Identification of these stages can help time development, make prudent decisions and anticipate crop response to management practices and environmental conditions.
Southwestern Corn Borer Monitoring – Week Ending 5/25/2024
With corn acres rapidly approaching tassel, southwestern corn borer traps are beginning to be deployed across the state. Limited data is available for this week but will become more abundant as the season progresses.
When should we initiate Irrigation to Enhance Corn Yield?
At the first hint of summer weather, there is often a rush to replenish moisture in corn fields with irrigation. However, inadequate soil moisture is not nearly as limiting as usually perceived. This article will discuss when to initiate irrigation based upon what is best for the corn crop.
Optimum Timing and Management for 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.
Grain Sorghum Planting and Early Management Recommendations
Grain sorghum has some unique characteristics differing from our major row crops. This article discusses key planting and management practices needed to successfully plant sorghum and get it off to a strong start this spring.
2024 Grain Sorghum Hybrid Suggestions
This article lists those sorghum hybrids which have demonstrated superior yields in the Mississippi Grain Sorghum Hybrid Trials. Thus, this is a great barometer to select the best adapted sorghum hybrids for your farm.
Improving Corn Response to Nitrogen Fertilizer
Corn response to nitrogen fertilizer is a dynamic situation that often becomes more challenging when rains abound. This article gives recommendations to improve corn response to nitrogen fertilizer and reduce risks in the Midsouth.
How to Assess Uneven Stands and Corn Replanting Methods
Assessing corn stands to make replant decisions should likely involve more than simply taking stand counts. This article discusses how emergence disparity affects corn yield potential, and methods to replant your crop, when needed.
When is the Cut-Off Date for Planting Corn?
When rain or other issues restrict planting opportunities, 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 at Mississippi State University.
Keys to Success for Early Corn Planting
Corn is very dependent on stand quality and uniformity to optimize productivity. Although things look promising for early planting this spring, there is typically considerably more risk associated with adverse weather for early plantings, compared to later in the spring. This article discusses how to assess corn planting suitability, strategies to improve your stand, and factors that affect what seeding rate you should plant.
Spring Nitrogen Fertilizer Recommendations for Wheat and other Small Grains
Our moist climate challenges our ability to fertilize wheat and other small grains. This article outlines best management practices for nitrogen application timing, fertilizer sources, rates and other important practices which can greatly enhance wheat or oat productivity. Nitrogen recommendations are also included for cereal rye grown for seed or grain production.
Identifying Wheat Growth Stages using the Feekes Scale
The Feekes scale is likely the most commonly used system to describe wheat and other small grain’s growth and development stages. Understanding of wheat plant development is important so that you may better time management inputs to optimize crop response. This article helps you identify specific wheat growth stages.

Cover Crop Termination and Preparation for Corn Planting
Cover crops can improve soil health and water quality and are being grown on more acres. However, their growth extends into the spring and may present challenges for primary crops, depending upon when you decide to terminate them with a burndown herbicide. We have been researching these dynamics so that we may implement strategies to realize benefits while minimize risk for corn production.
2024 Extension County Meetings Schedule
Mississippi State University Extension will be hosting several county row crop meetings in February. 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
2023 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.
2024 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 choices in the market. Thus, this is a great starting point and barometer for you to judge performance and select the best corn hybrids for your farm.
