Last year was a challenging year for insect pests of rice in Mississippi. In general, we experienced higher than normal populations of rice water weevil, rice stink bug, and fall armyworm. Luckily from the rice water weevil standpoint, the two
This update covers rice burndown considerations, hybrid insecticide seed treatments, and 2011 USDA Outlook Agriculture Forum – Rice Planting Intentions.
Sulfur in Mississippi Crop Production Sulfur is required in fairly large quantities by most crops. It is an essential building block in chlorophyll development and protein synthesis. Sulfur is also required by the rhizobia bacteria in legumes for nitrogen fixation.
Calcium and Magnesium For Mississippi Crops Calcium (Ca) and (Mg) magnesium are positively charged secondary nutrients. They are generally adequate in most Mississippi soils with favorable pH and organic matter levels. They affect acidity when applied to the soil, and
The 2010 Row Crop Short Course was held at Mississippi State University on December 6 – 8, 2010. As we expanded the Short Course in 2009, we also have adopted technology to record the oral and visual portions of the presentations.
In Mississippi, the rice water weevil is the most important early to mid season pest in rice. Three years of research have shown that foliar pyrethroid applications provide variable results, and may not always provide acceptable control.
With snow melting and warmer temperatures on the way, burndown should be taking place next week. I have included a video presentation for rice winter weed control. You can stream the video by clicking on view in a popup. The file can also be downloaded by clicking on Rice Winter Weed Burndown below.
Cotton producers in Mississippi planted approximately 425,000 acres of cotton in 2010. This was a 33% increase in acres compared to 2009. Approximately 5% of cotton in MS was planted to transgenic single gene Bt varieties and 90% of cotton acres was planted to dual toxin transgenic Bt varieties. The most popular varieties planted in 2010 were
With the current commodity prices, some suggest that the 2011 crop be ‘insured’ by applying micronutrients. Is this good policy for Mississippi field crops? These essential elements are required by plants in very small amounts: boron, zinc, molybdenum, iron, manganese,
There are several keys to successful wheat nitrogen fertilization in Mississippi. Split application of nitrogen fertilizer is likely more important for wheat than any other crop, including corn. This is because wheat nitrogen fertilization occurs during the wettest months of the year – in a high rainfall, warm regional climate conducive to nitrogen loss.
The Rice Seeding Rate Calculator has been uploaded. This is an excel file that will give seeding rates for selected rice varieties. I have uploaded a tutorial video that demonstrates how to use the program. You can download this file or you can click Play in Popup which will give you full streaming video. I also included a rice seeding rate chart which is a pdf version of the information.
For the past 15 years the only herbicide program that most producers have known was the use of glyphosate in Round Ready® crops. With glyphosate-resistant weeds becoming more of an issue there has been an increase in demand for alternative control options.
Poultry litter has long been used to provide nutrients for pastures, hay, and other crops in the south-central Mississippi broiler production region. Volatile fertilizer prices increased interest among cotton producers in using litter as a nutrient source. Fortunately, there is
Our 2010 rice variety trial data is now available. We also have released our 2010 Rice Research Report. If you have questions, please let me know. Here’s the link to the research report… 2010-rice-research-report-01122011 Here’s the link to the variety
We have posted our official variety trial results for soybeans and corn. You’ll find a link at the bottom of this post that will take you to our variety trial listings for both crops. The results are available as both
