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 2024 Mississippi Agricultural Industry Council Annual Convention. This event is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 24 starting at 8:00am.
Over the last 7 to 10 days, fall armyworm infestations in rice have increased a good bit. Currently pyrethroids are the only products labeled for fall armyworm management in rice. Since 2021 the performance of pyrethroids against fall armyworm has
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.
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.
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.
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.
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.
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.
At-planting: Since the development of widespread resistance to neonicotinoid seed treatments, we have been recommending the use of Acephate (Orthene) at planting, either as an overtreatment at 6.4 oz per cwt or up to a pound in-furrow. For several years,
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.
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.
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.
During 2023 multiple soybean OVT locations were observed for the presence of disease. The Verona, MS location was observed to have the most consistent frogeye leaf spot data across all of the varieties planted. Observations were made and those are reported in the corresponding data tables.
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.
The cultivars contained in the 2023 Mississippi State University Official Variety Trial (OVT), as well as several additional cultivars, were field-evaluated for their susceptibility/resistance to stem canker. Trials were conducted in Stoneville with toothpick-inoculated plants. Tables contain the average of the field observations (on a 0-9 scale) as well as an assessment of resistance to stem canker (R, MR, MS, S) based on the evaluations conducted.
