At the first sign of summer weather patterns, Midsouth corn growers often get nervous about moisture stress. However, inadequate soil moisture is not nearly as limiting as usually perceived – considering we have abundant moisture virtually all spring. In fact, excessive moisture can stress corn development and hamper yields, if we trigger irrigation too early.
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.
If rain or other issues have restricted 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.
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.
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.
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 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.
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
Cover crops can improve soil health and water quality and are being grown on more acres. However, their growth may extend into the spring and present challenges for primary crops. We are investigating these dynamics so that we may implement strategies to realize advantages while minimizing risk. Corn production presents issues that we will address.
LOUISIANA GOVERNOR JOINS 117 RESEARCHERS, FARMERS AND CONSULTANTS WHO WILL ADDRESS MID-SOUTH FARMERS IN BATON ROUGE THIS MONTH Governor John Bel Edwards will give the Keynote address as he joins researchers, farmers and Certified Crop Advisors, who will speak at
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.
Non-irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2022 season. Curvularia leaf spot was the most prevalent foliar disease observed. Data are presented as the severity of each disease from each irrigated location on a 0-9 scale for each of the hybrids included in the irrigated location evaluations. Presently, the evaluations from the mpm-irrigated locations (n=4) are included in the current post.
Irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2022 season. Curvularia leaf spot was the most prevalent foliar disease observed. A limited amount of southern rust was observed at two locations. Data are presented as the severity of each disease from each irrigated location on a 0-9 scale for each of the hybrids included in the irrigated location evaluations. Presently, the evaluations from the irrigated locations (n=6) are included in the current post.
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.
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.
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 potential aflatoxin issues can greatly help improve your harvest efficiency and success.
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 crop.
Up until the past week the disease situation in the MS corn crop has been rather quiet. As the crop matures, additional diseases will likely be observed. Aside from Curvularia leaf spot being the most noticeable disease throughout the state, I have received numerous calls regarding corn smut as well as Physoderma brown spot.
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 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.
We welcome you to attend the Row Crop Update at the 2022 Mississippi Agricultural Industry Council Annual Convention. This event is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 20 starting at 8:00am.
