At the first hint of summer weather, there is often a rush to replenish moisture in corn fields with irrigation. However, this year rains have delayed needs for corn irrigation much later than normal. Since most corn has now tasseled, how will this affect irrigation management?
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 chance for a profitable response.
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.
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.
Corn response to nitrogen fertilizer is a dynamic situation that becomes considerably more challenging when rain is plentiful. This article gives recommendations to improve corn response to nitrogen fertilizer and reduce risks in the Midsouth.
When rain or other issues limit planting opportunities, you may be wondering how to proceed with crop planting intentions. This publication 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.
In these tough economic times we devote considerable effort to trimming the fat and focusing inputs where they will improve return on investment. The limiting factors will vary, but these are some of many potential factors which are very important.
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. Complete results, including yields and plant characteristics from this year’s trials are published here.
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.

Tight margins and high expenses tempt us to consider managing crop residue with fire, rather than tillage or other alternatives. However, fire will reduce recycling of organic matter and nutrients. Thus, burning produces several negative consequences that can definitely diminish profit.
Corn kernel set near the ear tip may vary considerably depending on a number of cultural and environmental factors. These kernels have issues when the plant can’t supply enough energy to support all of them. Therefore, if we want to improve our yields, we need to recognize why kernel set is less than desired, so we can improve management in the future.
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.
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.
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.
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.
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.

Mississippi State University will be hosting a field day on August 24 in Monroe County to tour soybean varieties that are currently being evaluated for tolerance to iron deficiency chlorosis. Light refreshments will be available at 7:30 a.m. with the
Please mark your calendar and share the word about the upcoming MSU Corn and Soybean Field Days scheduled in the coming weeks. These field days will feature MSU Corn Hybrid and Soybean Variety Demonstration Plots which contain premier genetics from seed companies serving the Midsouth region. Seed company representatives and MSU Extension Specialists will discuss varieties, expectations and address questions.

Corn is very dependent on the stand achieved to optimize productivity. So far this spring temperatures have been much warmer than normal, which definitely benefit corn planting opportunities and outcome. However, next week may bring other challenges. This article discusses how to assess corn planting suitability, strategies to improve your stand, and factors that affect what seeding rate you should plant.
