  • Impact of volunteer GM maize on conventional crops is low

    A recent EU-supported study has analysed the development of volunteer or 'rogue' GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU's threshold of 0.9 per cent for incidental GM content. Scientific data on the role of maize volunteers on cross-pollination is limited. The most detailed studies have been conducted in ...

  • Committee advises halt to Indian Bt crop trials

    A technical expert committee, appointed by the Supreme Court of India to advise upon open field trials for genetically modified (GM) crops, has recommended a ten-year moratorium on all Bt (Bacillus thuringiensis) food crop trials. Bt crops are GM plants that kill insects using a toxic protein from the Bt soil ...

  • Breweries persuade drought-hit farmers to switch crops

    A partnership between academics and a beer company, which sent sorghum prices soaring in East Africa, has been highlighted as a way of harnessing agricultural research to fight the effects of drought such as the one in the Horn of Africa. The Kenya Agricultural Research Institute (KARI) linked up with Kenya-based East African Breweries Limited (EABL) in 2009 to address a missing link between ...

  • Agronomists, crop and soil scientists convene in Long Beach

    What would be the impact of the next green revolution on global food security? How can soil help lessen the impacts of climate change? To what extent can biofuels help make America energy independent? These topics and others of public interest will be discussed at the International Annual Meetings of the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science ...

  • Dealing with difficult powdery mildew infections on ornamental crops

    We are now at the peak of the powdery mildew season and, with increasing temperatures and dry weather conditions, susceptible crops are likely to be at high risk of infection. The pathogen There are five different powdery mildew species which attack ornamental crops in the UK. Erysiphe ssp. – this pathogen is mainly ...

  • International crop breeding programme needed for African farming

    Climate change poses a large threat to African agriculture, but there is little research on how to respond. A recent study indicates that traditional adaptation methods are not enough and international collaboration is needed in 'planned adaptation' by collecting and conserving certain crops for the future. A large proportion of the African population - mainly the poor - depend on agriculture for ...

  • Coffee pest spreading to other crops in East Africa

    East Africa's horticulture could face a severe crisis due to 'species jump' — whereby a disease moves from a known host to new and unusual ones — affecting fruits, vegetables, and medicinal and ornamental plants. Researchers in Uganda have discovered that the Black Coffee Twig Borer, a devastating coffee pest, has crossed over from Robusta coffee to about 40 plant  ...

  • Time is ticking for some crop`s wild relatives

    New edge of extinction research is creating a revival of conservation and interest in what these old plants mean to the future Experts and photos available on this topic! A botanist brings a species of alfalfa from Siberia, to the United States. His hope? The plant survives, and leads to a new winter-hardy alfalfa.  But what also happened during this time in ...

  • A step forward to making crops tolerant to severe drought

    An international consortium of researchers led by Wageningen University & Research in the Netherlands, has sequenced the genome of the ‘resurrection plant’ Xerophyta viscosa. Today the team publishes the DNA sequence in Nature Plants. In their paper, the team reveals a genetic ‘footprint’ of the amazing ability of this plant to tolerate severe drought for long periods ...

  • Variable crop sowing dates `produce higher yields`

    Cropping systems with variable sowing dates adapted to changing climatic conditions — as opposed to those with fixed sowing dates — will result in increased mean future crop yields, a modelling study has found. Multiple cropping systems, including growing two or more crops at the same time on the same plot ...

  • 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 years. ...

  • North Florida farmers are using sesame as a rotation crop

    In between seasons of corn, peanut, and cotton, North Florida farmers were interested in growing a rotation crop that could withstand the wilting heat of summer and be harvested by machine. So, since 2011, University of Florida researchers have been experimenting with growing the tiny seeds you find on top of hamburger buns or garnishing salads – sesame – as a viable, money-making ...

  • Crop breeding gets boost from sweet potatoes

    In Uganda, the sweet potato is a major staple crop. Behind China and Nigeria, Uganda produces the most sweet potatoes in the world. Nationwide, families grow the crop to feed themselves, their livestock and to use as a source of income. Small scale agricultural operations use a large number of sweet potato varieties in their planting. These varieties are steadily being lost due to weevils, sweet ...

  • National Survey on Cover Crops Seeks Farmer Participation

    Farmers are invited to share their thoughts on cover crops—whether or not they use cover crops themselves—in a national survey, now in its third year of collecting valuable data on the increasingly popular management practice. The results, which will be released this summer, will help growers, researchers, agricultural advisors, ag retailers and policymakers more effectively address ...

  • USDA Unveils New Improvement to Streamline Crop Reporting

     U.S. Department of Agriculture (USDA) today announced that farmers and ranchers filing crop acreage reports with the Farm Service Agency (FSA) and participating insurance providers approved by the Risk Management Agency (RMA) now can provide the common information from their acreage reports at one office and the information will be electronically shared with the other location. This new ...

  • Bee pollination improves crop quality as well as quantity

    Bee pollination improves the shape, weight and shelf-life of strawberries, contributing a staggering €1.05 billion to the European strawberry market per year, new research suggests. By blocking bees from a set of plants, the researchers demonstrated the substantial effects of bee pollination on the quality of the fruit. It is well established that insect pollination increases the quantity of ...

  • Maximising the yield of agricultural crop residues and biomass from forestry

    There is a huge potential for yield increase of agricultural crop residues and biomass from forestry in the European Union, Ukraine, Russia and Belarus. In a study for the European Commission, Ecofys has investigated the realistic and technical-sustainable potential for these regions. The research team developed and assessed best practice strategies for residue yield increase with regard to their ...

  • Project aims to tame wild radish impact in cropping regions

    Wild radish and its resistance to herbicides is under scrutiny in Victoria’s Wimmera-Mallee cropping region. A Grains Research and Development Corporation “fast track project”, instigated by the GRDC’s southern Regional Cropping Solutions Networks (RCSN), aims to map the extent of herbicide resistance in wild radish and other broadleaf weeds and increase awareness about ...

  • The highs and lows of 2010 in the developing world

    2010 was a year of contrasts for those seeking to boost the role of science in the development agenda. Many new initiatives were launched; some took root, others ran into difficulties. And progress in meeting big challenges, such as conserving biodiversity and tackling climate change, remained slow. Several organisations had chosen 2010 as the target date for achieving specific goals. Perhaps the ...
