AgCenter scientist closes in on better sprayer cleanout

An LSU AgCenter researcher is getting closer to developing a better way to clean sprayers that are used to apply farm chemicals.

Zhijun Liu has spent the past two years working to formulate a plant-based solution that effectively removes pesticide residue. Sprayers must be thoroughly cleaned to get rid of leftover product, which can damage the equipment itself as well as subsequent crops being sprayed.

AgCenter scientists study new ways to control weeds

Most farmers depend on herbicides to keep troublesome weed populations in check. But some of these unwanted plants manage to survive regardless of the chemical sprayed on them, creating a supply of seed that fuels future generations of weeds.

Lauren Lazaro, an LSU AgCenter weed scientist, is studying ways to reduce the amount of weed seed left in fields at the end of the season.

Corn, soybean studies search for improved yields

In a new study measuring various factors affecting corn yield, AgCenter researchers are working to evaluate the effects of tillage, plant populations and fertilizer use along with insecticide rates and fungicide applications.

The research involves deep tillage versus no deep tillage; plant populations of 40,000 versus 32,000 plants per acre; starter fertilizer versus no starter fertilizer; foliar fungicide versus no foliar fungicide; and insecticide rates of Poncho 1250 versus Poncho 250. In addition, a higher rate of fertilizer will be used to compare with the AgCenter recommended rates.

LSU AgCenter researcher looks at no-till systems

Syam Dodla, LSU AgCenter agronomist, is studying fertilization rates in no-till fields for corn and soybeans.

“Compared to conventionally tilled soils, soils in no-till fields have different structure and properties with varying amounts of nutrients found in layers of the soil profile,” he said.

Making informed decisions is critical to turning profit

Profitability is essential for a farming operation’s survival. But determining the point where losses turn into profits is always a moving target and consists of many variables.

To help simplify the process, Michael Deliberto, an economist in the LSU AgCenter Department of Agricultural Economics and Agribusiness, has helped develop tools that allow producers to input farm operation data and determine the point of profitability using factors such as cost inputs, land rental rates and the market price of the commodity.

Pest management research could save producers money

New research on pests in soybeans and corn should decrease the amount of money growers spend on pest control.

“After the cold weather we had this winter, we were expecting the numbers of redbanded stink bugs to be lower,” said LSU AgCenter entomologist Jeff Davis.

Scientists study irrigation practices

The 2017-18 wheat crop was outstanding from a production and research standpoint, according to LSU AgCenter wheat breeder Steve Harrison.

Harrison said weather conditions made for a nearly perfect growing season.

“We had the highest yields and the highest quality ever,” Harrison said. “We also had the lowest acreage.”

Scientists study irrigation practices

As irrigation has grown more common on Louisiana farms, LSU AgCenter researchers are studying the most efficient and beneficial ways to apply water to crops.

While farmers implement long-term fixes to improve the soil’s water-holding capacity — such as planting cover crops and experimenting with poultry litter as fertilizer — irrigation is an immediate solution in dry times.

Soil scientists research nitrogen efficiency, silicon for plant protection

National studies of commercial enhanced-efficiency nitrogen fertilizers on row crops have shown some success in improving efficiency of plant uptake and decreasing losses of greenhouse gases while minimizing nitrate runoff.

Until recently these fertilizer compounds have not been adequately tested in the hotter, more humid South, according to Jim Wang, a soil chemist with the LSU AgCenter.

Variety and hybrid trials are building blocks for yield improvement

Finding a variety or hybrid that will perform to its full potential is a goal all producers strive for. While it may not be as difficult as finding a needle in a haystack, it does take a trial-and-error approach.

Helping to mitigate the error part, scientists with the LSU AgCenter continue to conduct core block demonstration plots at sites across Louisiana for crops, including corn, sorghum, soybeans and wheat. These locations serve as test plots for many varieties and hybrids and give producers a firsthand look at how well they will perform based on soil types, insect and disease pressure, cultural practices and other factors.
