N.C. A&T food scientist develops process for allergen-free peanuts

...nut producing region in the nation. Worldwide, the legume is even more important from an economic development standpoint. In developing nations, and Africa in particular, the soils and climate are especially suitable for peanuts. Peanuts are not only important commercially, but nutritionally as well. Pac...

On-farm research shows farmers that they can use less nitrogen

...rence. This indicates that the forage grass and/or legume gave enough nitrogen back to the soil to feed the following year's corn crop, he said. Forage quality was not negatively impacted either. For example, after farmer Mike Kiechle of Garden of Eden Farm in Philadelphia, N.Y., cut the excess nitrogen ...

Climate change threatens wild relatives of key crops

...so examined wild relatives of cowpea, a nutritious legume farmed widely in Africa. It found that only two of 48 species might disappear. However, the authors predict that most wild cowpeas will decline in numbers because climatic changes will push them out of many areas they currently inhabit. "Our resu...

Scientists discover cost-effective ways to improve crop output in Uganda

...hort-term fallow using mucuna, a herbaceous annual legume Cowpea rotation with sorghum Manure application Nitrogen and phosphorus applied as fertilizer Reduced tillage Several soil fertility management practices and reduced tillage were cost effective in increasing sorghum crop yield in the region ...

DOE JGI, VBI describe disease mechanisms of sudden oak death, related soybean pathogens

...llion annually. Soybean, the world's most valuable legume crop, is of particular interest to DOE because it is the principal source of biodiesel, a renewable, alternative fuel. Biodiesel has the highest energy content of any alternative fuel and is significantly more environmentally friendly than comparabl...

Legume compounds may help cancer treatment

...have identified several compounds derived from the legume interaction with rhizobium bacteria that show strong anti-angiogenic activity. "They are promising therapeutic molecules which clearly warrant further investigation," Professor Parish said. CILR Director Professor Peter Gresshoff said the current res...

Plants, too, have ways to manage freeloaders

...dulation. This could explain why soybean and other legume crops in fields inoculated with the supposedly most efficient strain of nitrogen-fixing bacteria do not always take up that strain - an expensive problem for farmers. "The most effective strain is not always best at competing for nodules," Simms said...

New maps reveal true extent of human footprint on Earth

...ve increasingly cleared forests to grow soybean, a legume that has never been a traditional crop of Latin America. Scientists say the surge in soybean production there has a lot to do with the booming demand for soy all the way at the other end of the world - in China. Meanwhile, Monfreda notes, long-time s...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...n of symbiotic hemoglobins in nodules of the model legume Lotus japonicus, enabling researchers to assess for the first time the role and importance of these proteins in plants. The results of the study indicate that symbiotic hemoglobins are important for oxygen transport and energy metabolism in plant roo...

Plants respond similarly to signals from friends, enemies

...the NC State researchers discovered that the model legume Lotus japonicus responded similarly to signals from both rhizobia, the friends that fix nitrogen for the plant, and root-knot nematodes, the parasitic foes that want to harm the plant. Signals from both outsiders induce rapid changes in distribution ...

Drought reduces nitrogen-fixing in legumes

...hizobes are capable of establishing symbiosis with legume plants giving rise to a new structure: the nodule. On the one hand, the plant benefits from the micro-organism, that takes on the task of capturing nitrogen from the air and converting it into ammonia in such a way that the plant can use it. This am...
