The evolution of cotton cultivars has led to higher yield potentials and shorter growing seasons compared to the historical full season cultivars favored in the Mid-South. These newer, faster fruiting cultivars may require more nutrients than older outdated cultivars. Recently,
The North Mississippi Research and Extension Center’s Agronomic Row Crops Field Day on Thursday, August 7 will present the latest research to the area’s row-crop farmers and consultants. The field day will be from 8 a.m. to 1:30 p.m. at the Lee County Agri-Center Magnolia Conference Center on Highway 145 South in Verona.
Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field. Nutrient issues in rice can take on
Last week’s weather pattern in the Delta provided near perfect conditions for rice blast (Pyricularia grisea) to occur. Rice blast is generally categorized by the plant part infected (e.g., leaf, neck, panicle). Blast favors mild humid weather, frequent rainfall, and
Diagnosing nutrient deficiencies is not rocket science, but can be cumbersome. Many nutrient related issues occur early in season and can sometimes mimic herbicide injury in appearance. In many instances it is difficult to tell the two apart. Most often
More and more corn growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the appropriate timing and crop response.
A corn, cotton, peanut, and soybean field day is scheduled for June 17th at the Delta Research and Extension Center in Stoneville, MS. The general theme of the field day will include pertinent information for mid-season row crop issues.
Maintaining nitrogen applied as a pre-flood application is an important topic for rice farmers. Nitrogen can be lost by at least three different methods, two of which are considered to be bad since the N will become unavailable for plant uptake.
Considering the abundant rainfall we experienced during April and typically have, it is usually very important to optimize nitrogen fertilizer management. This newsletter discusses best management practices for corn nitrogen fertilization. These recommendations reduce the risk of nitrogen loss and can improve crop response when wet weather is prevalent during the spring.
Dr. Jeff Johnson, Head of the Delta Research and Extension Center, has assigned responsibility for Extension in rice to Dr. Bobby Golden. Dr. Golden will serve in this capacity until a suitable candidate is identified for the Rice Agronomist/Extension Specialist
In Mississippi, research indicates that management of medium-grain varieties is similar to that of long-grain varieties.
Annual report of Mississippi Rice Promotion Board is now available online.
Wet, saturated soils and variable environmental conditions certainly complicate issues associated with nitrogen fertilization of wheat fields in the Mid-South. This article gives guidelines for getting better wheat response to your fertilizer dollars.
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
I have been fielding calls from many producers and consultants within the last week about zinc applications with corn planting season shortly around the corner. Zinc deficiency in corn generally occurs early in the season (V2-V5) and manifests itself by
Attached please find the agenda for the Delta Ag Expo in Cleveland, MS. Make careful note that the dates of the meeting have changed from previous years due to a minor scheduling conflict with the Bolivar County Exposition Center.
As you look over your fields this winter, be thankful for the tons of potassium (K) present in every acre. It is the most abundant mineral macro-nutrient on earth, which is good because most crops utilize large quantities of it.
The 2013 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University from December 2 – 4, 2013. The 2013 Row Crop Short Course will begin with an irrigation symposium hosted
A common question that I have received from numerous consultants over the last several days is as follows. Hey don’t hammer me, but what happens if we mistakenly burned our corn stubble after we spread fall mixed good fertilizer and
The Soybean Minute is a new radio program that can be heard on the Mississippi AgriNews Network. These reports, sponsored by the Mississippi Soybean Promotion Board and the United Soybean Board, offer the latest information on soybean production in Mississippi.
Corn diseases continue to be a hot topic throughout the MS corn production area. Most field calls have been regarding common rust as well as northern corn leaf blight. However, over the past two weeks numerous calls regarding nutrient and irrigation stresses have been answered that were initially thought to be disease. In addition, with the recent information from Louisiana regarding the observation of Goss’s wilt in LA (a rare event in their production system) agriculturists should know that disease as well as crop stresses can be initially misdiagnosed as diseases that are not normally present in our production system such as Goss’s wilt.
For all intensive purposes cotton planting has been completed in Mississippi for 2013. In my estimation the majority of the 2013 crop is two to four weeks behind normal. The youngest cotton in the state is at 1 to 2
More and more growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the potential yield response and appropriate timing.
Nitrogen is important for crop growth and production. Managing this valuable input for maximum plant availability is critical to ensure optimum economic returns while minimizing the potential for negative environmental effects. Urea is the standard N fertilizer product for rice
Persistent rainfall has periodically saturated corn fields for several weeks this spring, prompting questions regarding potential nitrogen fertilizer loss. This article gives guidelines for estimating potential N loss.
