Soybean Management Symposium Series: Future Dates (2/25 Tunica, MS; 2/26 Verona (morning); 2/26 Macon, MS (afternoon))
Three more opportunities exist for ag-related personnel to attend the Mississippi Soybean Promotion Board sponsored seminar series on nutrition management, nematode sampling and management, and irrigation practices. Meetings are scheduled next week in Tunica (2/25; 9 am), Verona (2/26; 9 am), and Macon (2/26; 2:30 pm).
Soybean Symposium Today, Feb. 10th at Capps Center
Farmers can hear from Mississippi State University (MSU) experts today in a series of soybean seminars sponsored by the Mississippi Soybean Promotion Board (MSPB) and Mississippi Farm Bureau Federation (MFBF). The goal of the seminars, titled “Digging Deeper: Managing Unseen
2014 Mississippi Small Plot Cotton Variety Trial Data
Find below All data from the 2014 Small Plot Cotton Official Variety Trial (OVT). During 2014, small plot cotton variety trials were conducted near the following locations; Brooksville, Clarksdale, Itta Bena, Senatobia, Starkville, Stoneville, Tunica, and Verona. The Cotton OVT
2014 Delta Area Rice Meeting
The 2014 Delta area/Bolivar Co. Rice Meeting will be held at the Bolivar Co. Extension office on December 4, 2014. Mississippi rice producers, industry professionals, and other interested parties are invited to listen to presentations from MSU research and Extension
Not all Boll Rots are caused by Bacterial Blight
Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders.
2014 Preliminary Rice Variety Trial Data
Find below the Preliminary version of the 2014 Small Plot Official Rice Variety Trial. During 2014, small plot rice variety trials were conducted near the following locations; Choctaw, Clarksdale, Drew, Hollandale, Shaw, Stoneville, and Tunica. Variety trial data is presented
Identifying Soils that “Seal” and Improving Irrigation Application Efficiency in “Sealing” Soils
This summer we had multiple conversations with producers that either irrigated or had significant rainfall events on their field, but the soil moisture sensors below the 6 inch depth never “detected” the irrigation or rainfall event (see https://www.mississippi-crops.com/2014/06/26/is-my-soil-moisture-sensor-broke/ ).
Late Season Potash Deficiency in Cotton
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,
Keys to Diagnosing Common Nutrient Deficiencies in Rice
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
Rice Stink Bugs in Mississippi Rice
As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations.
Rice Leaf Blast Confirmed in Mississippi
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
It’s okay to let it down!
It’s okay to let it down! Defining proper flooding of rice can be somewhat challenging depending who you talk to. One thing is for sure, to take advantage of the cost saving of straight levees and multiple inlet rice production,
Scouting Cotton for Bacterial Blight in 2014
Once again, bacterial blight has been observed in the MS cotton crop. At present, several fields in the south and north Delta as well as a single field in east MS have been observed to contain bacterial blight infected cotton leaves. To date (July 8, 2014), a single cotton variety has been reported to be infected in all fields.
Armyworms in Rice, Again!
It appears that 2014 is going to be the year of the armyworm in rice. I have had numerous calls, texts, and Tweets about armyworms in rice over the last week. If you have not had them in your rice to this point, consider yourself very lucky.
Programing a Surge Valve
We are having lots of questions concerning the proper set up of surge valves. First, please consider some of the basic terminology associated with furrow irrigation. We encourage you to visit http://www.youtube.com/watch?v=46sSLFBUrh8 and view the video before continuing. Phases
Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation
With water being one of the most expensive inputs of the rice producer, utilizing methods to limit the amount of water used makes economic sense. Adoption of multiple inlet irrigation has allowed producers to reduce water consumption. Water use with
Diagnosing Nutrient Deficiencies in Mississippi Soybeans
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
Soybean Crop Update and Replant Decisions
According to the USDA National Agricultural Statistics Service in Mississippi, 89% of the soybean acreage is planted as of the week ending June 8, 2014. At this time, 82% of the crop is emerged. The remaining acres to be planted
Armyworms in Rice
Similar to most years when we have armyworms in wheat, there is the threat of having armyworms in seedling rice. We know of at least one rice field in Mississippi that was sprayed earlier this week. In general, damage from armyworms will not impact rice yields at this time of year unless they are beginning to reduce plant stand. This is especially true in hybrid rice planted at low seeding rates.
Protecting Your Preflood Nitrogen
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.
Insecticide Seed Treatments and Rice Water Weevil Management in Rice
A little rice has started to go to flood in Mississippi this week and that means it is time to start thinking about rice water weevil. Overall, the majority of the crop is behind because of all of the rain that we have had across the Delta over the last several weeks. In general, the rice that is currently being flooded was some of the earliest planted. As a result, the early rice has endured a lot of rainfall and adverse conditions.
Tips to Improve Nitrogen Response for Mid-South Corn
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.
Soybean Seedling Emergence Issues: Environmental Stress Compounding Factors
A substantial number of soybean acres have been reported to be affected by seedling disease. However, the majority of the field seedling issues can be blamed on poor environmental conditions following the planting that occurred around Easter (between April 14 and 19) and some of the residual herbicide products applied.
Tips to Improve Rice Fungicide Application Effectiveness
Before the rice season gets into the full swing, consider several important fungicide application strategies before the mid-season fungicide application. Preventing fungicide-resistance from developing is the first step in managing the issue.
