OSU Expert: Corn Stalks Are An Inexpensive Feed Source
Livestock producers looking for a relatively easy and inexpensive feed source can turn to harvested cornfields for the answer. The residue left on the field after harvesting corn can be used to meet the nutrient needs of ruminant livestock in early to mid-gestation, according to a forage expert from Ohio State University’s College of Food, Agricultural, and Environmental Sciences. As the ...

Borage plant frost protected by Oenosan
Borage plant frost protected by Oenosan Borage or Borago officinalis is an annual flowering plant. Borage is a herb native to the mediterranean region but nowadays it is found all over Europe from Denmark to the south of France. Its a self seeding plant and the leaves are edible. The plant has many useful characteristics and therefore it’s commercial ...

Earthworms decompose GM maize
Pest-resistant genetically modified (GM) maize makes up an increasing proportion of maize grown commercially in the EU. A new study shows that earthworms may help break down the toxins produced by GM maize. GM maize (Bt-maize) plants are engineered to produce 'cry' proteins that are toxic to the European corn borer, a major insect pest responsible for corn crop losses. Recent studies have shown ...

Late Corn Better Than Blighted Corn
Growers whose corn crops were harmed by excessive rain in April and May likely will have enough growing days left in the season if they replant in the next two to three weeks, according to an Ohio State University agronomist. “If they replanted soon, it would probably be much better than to have a poor stand,” said Peter Thomison, an agronomist with Ohio State University Extension, ...

Tasty strawberries with LEDs
Strawberries taste better when they are illuminated in the autumn. The vitamin C content and the production has increased as well. That is the result of research by Wageningen UR Greenhouse Hortriculture. Strawberries were planted on 20 August in a greenhouse of IDC Flavour at Wageningen UR Greenhouse Horticulture in Bleiswijk. Three lighting systems and five different varieties are being ...

UF/IFAS imaging system can detect citrus greening before symptoms show
A time-lapse polarized imaging system may help citrus growers detect greening before the plant’s leaves show symptoms, which should help growers as they try to fend off the deadly disease, a new University of Florida Institute of Food and Agricultural Sciences study shows. For the new study, Won Suk “Daniel” Lee and Alireza Pourreza wanted to know how early citrus leaves with ...

Plant characteristics can predict ecosystem services provided by green roofs
Simple characteristics of plant species — such as height or leaf size — can be used to predict the ecosystem services provided by the green roofs they grow on, a new study suggests. The researchers suggest that their method could be used to screen the thousands of potential plant species in order to optimize green roof design. Green roofs on buildings are able to provide multiple ...

Global programme seeks to contain serious threat to the world’s bananas
A fungus poses major risks to the world's banana production and could cause vast commercial losses and even greater damage to the livelihoods of the 400 million people who rely on the world's most traded fruit as a staple food or source of income. FAO and its partners Bioversity International, the International Institute of Tropical Agriculture and the World Banana Forum have launched a global ...

Vegetables can absorb heavy metals from contaminated irrigation water
Certain vegetables take up heavy metals from contaminated water used for irrigation, a new study finds. The researchers grew vegetables in greenhouses similar to field conditions in Greece and found that concentrations of nickel and chromium increased in potatoes and onions, but not in carrots, when irrigated with water containing contaminant levels similar to those found in industrial ...

Choice of winter cover crop mixture steers summer crop yield
Scientists from Wageningen University & Research demonstrate that the productivity of a next main crop can be manipulated through the choice of species in a preceding winter cover crop mixture. They report their latest findings in the Journal of Applied Ecology of 2nd of June. With their publication, the scientist agree with recommendations of FAO to included cover crops in rotations, on ...

Florida citrus growers: 80 percent of trees infected by greening
Florida’s citrus growers say as much as 90 percent of their acreage and 80 percent of their trees are infected by the deadly greening disease, which is making a huge dent in the state’s $10.7 billion citrus industry, a new University of Florida Institute of Food and Agricultural Sciences survey shows. The survey, conducted in March 2015, shows the first grower-based estimates of both ...

Purple limes and blood oranges could be next for Florida citrus
University of Florida horticulture scientist Manjul Dutt is hoping to turn your next margarita on its head by making it a lovely lavender instead of passé pale green. Dutt and Jude Grosser from the UF Citrus Research and Education Center are developing genetically engineered limes containing some similar genetic factors that are expressed in grape skin and blood orange pulp. These ...

How container-grown plants capture sprinkler irrigation water
As the container nursery industry faces severe restrictions on water use, researchers are looking to identify ways to minimize watering needs and eliminate excess watering. The authors of a new study say that understanding container-grown plants' capacity to "capture" sprinkler irrigation water can give growers important tools that help them adjust irrigation rates, reduce water use, and produce ...

America`s Emerging Bioeconomy
AMES, Iowa, August 30, 2007 (ENS) - Robert Anex wants to know what would happen if the increasing demand for ethanol prompts American farmers to decide against crop rotation and plant corn on the same fields, year after year. This spring farmers responded to the ethanol industry's demand for grain by increasing their corn acreage by 19 percent over last year, according to U.S. Department of ...

Scientists Develop Fast-Growing Sorghum for Biofuel
COLLEGE STATION, Texas, October 9, 2007 (ENS) - American cars and trucks may soon be fueled with sorghum. Not used widely as a food grain in the United States, sorghum is one of the five top cereal crops in the world, along with wheat, oats, corn, and barley. It was cultivated in Egypt in ancient times, and Africa still is the largest producer of sorghum today. Now, energy crop company Ceres, ...

Some Midwest farmers` crops falter in record rains
Weeks of record rainfalls drenched Don Lamb's cornfields this summer, drowning some plants and leaving others yellowed, 2 feet tall and capable of producing little, if any, grain. The 48-year-old central Indiana farmer can't recall anything like the deluges he's seen from late May on this summer; the latest was a 4-inch downpour a week ago. Neither can his father, who's been farming for 50 ...

UF/IFAS avocado irrigation app should save money, water
Avocado growers now know that a University of Florida Institute of Food and Agricultural Sciences mobile irrigation app works well to save money while maintaining crop yields. This data, reported in a new study, is critical for an industry that has a $100 million a year economic impact on Florida. It’s also important because agriculture uses about 70 percent of the world’s water, the ...

Research confirms first glyphosate resistant wild radish
The world’s first populations of glyphosate resistant wild radish will be announced at Perth’s Agribusiness Crop Updates, but researchers stress further cases can be minimised if farmers adopt diverse control strategies. Australian Herbicide Resistance Initiative (AHRI) research has confirmed glyphosate resistance in three populations of wild radish, all from different locations in ...

Warming Climate Undermines World Food Supply
Global agriculture could go into steep, unanticipated declines due to complications that scientists have so far inadequately considered, say three new reports authored by U.S. and international researchers. Developing countries may lose 334 million acres of prime farm land to climate change in the next 50 years, scientists estimate. After mid-century, continuing temperature rises, expected to ...
