About three decades ago, as fields in Louisiana choked on nearly uncontrollable weed populations, the 1981 state average soybean yield was a low 21 bushels per acre.
Foliar applications of iron may provide some opportunities to reduce the impact of Cercospora leaf blight in soybeans.
LSU AgCenter economist Kurt Guidry is conducting a survey to find out howthe AgCenter can better serve industry stakeholders through research and extension programs.
Feral hogs continue to be a major problem in the state, and research is being conducted to reduce their numbers, said LSU AgCenter animal scientist Glen Gentry.
Beatrix Haggard, LSU AgCenter upland crops fertility specialist, is participating in a number of studies to improve field corn and soybean yields. One of those projects is evaluating the use of products to enhance nitrogen efficiency for field corn.
Ron Levy, LSU AgCenter soybean specialist, said 39 onfarm soybean demonstrations were planted in 2015 across the state, including one in Washington Parish for the first time.
Weather has hampered Dustin Harrell’s soybean agronomy project this year.“This has been a trying year for us, but it is representative of our area,” said Harrell, an LSU AgCenter agronomist. Many growers in southwest Louisiana were unable to plant soybeans because of adverse weather conditions.
Many scientists look for genes that are expressed in a particular way, such as for yield or plant stem strength. But Zhi-Yuan Chen is looking for genes that can make soybeans more resistant to infection from the soybean rust pathogen.
While disease can wreak havoc on soybean or cotton crops, grain sorghum may be less likely to suffer from a disease outbreak. Trey Price, a plant pathologist at the Macon Ridge Research Station in Winnsboro, said the odds are low that a grower will have to make a fungicide application for disease control in grain sorghum most years.
LSU AgCenter entomologist Julien Beuzelin is in the second year of a study, being conducted at the Dean Lee Research and Extension Center in Alexandria, to see how irrigation and concentration of salts in soil affect soybean looper growth.
Variability in Louisiana’s climate seem to be causing changes in the Louisiana population of the redbanded stink bug, said Jeff Davis, LSU entomologist.
The soybean looper is a destructive pest on soybeans capable of defoliating fields if left unchecked. It can be difficult to control because of its resistance to many insecticides.
2015 has been a difficult year for the LSU AgCenter wheat and oat breeding program.“This is my 30th season,” said AgCenter wheat breeder Steve Harrison. “And this is probably the worst set of conditions I’ve seen.”
As concern about the future of water resources grows, researchers at the LSU AgCenter’s Red River Research Station in Bossier City are identifying ways to help farmers improve irrigation efficiency.
LSU AgCenter entomologists are evaluating programs that crop consultants and farmers use to control pests in soybeans across the state.The project evaluates the tools growers use and compares them to new approaches and new tools that either are available or will be in the near future, said LSU AgCenter entomologist David Kerns.
The Louisiana Soybean and Grain Research and Promotion Board directs your checkoff funds to research projects that address Louisiana’s most important production and marketing issues.
Sugarcane aphids in Louisiana transitioned from sugarcane to grain sorghum in 2013 – some of the first such colonization in America. Since then, this invasive insect species has rapidly spread to all sorghum-producing parishes, decreasing quality and yield and causing catastrophic crop losses in 2014.
Unrelenting rains that delayed planting of many Louisiana crops may have set the stage for a tougher-than usual battle with weeds this year.
Since 2005, the Soybean and Grain Research and Promotion Board has provided monies for an AgCenter Communications project to develop a research report highlighting board-funded projects. This publication serves as a report to soybean and small grain producers about the results from LSU AgCenter projects that their check-off dollars funded. It also serves as a marketing piece for the board and grain industry.
