  • 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 ...

  • UF/IFAS study: Sweet potato crop shows promise as feed and fuel

    As some Florida growers try to find new crops and the demand for biofuel stock increases globally, University of Florida Institute of Food and Agricultural Sciences researchers have found that sweet potato vines, usually thrown out during harvest, can serve well as livestock feed while the roots are an ideal source for biofuel. This could be a key finding for the agriculture industry in Florida ...

  • Perfect storm for potato blight

    With crop values creeping up, the need to protect is becoming ever more important to growers. However, this season’s blight threat has triggered the need for tighter spray intervals – indeed five days between applications is common – which is leading to increasing demand and potentially some product shortages in the range of fungicides available to fight potato blight. ...

  • Increasing potato production

    Despite sophisticated nutrient management of potato crops, quality and yield still see wide variability. Although nutrients are already well understood, the influence of other environmental factors remains understudied. A research team from Michigan State University conducted a study to determine how the chemical and physical properties of soil, along with the light waves the plant absorbs and ...

  • Improving the productivity of tropical potato cultivation

    Potatoes thrive in tropical highlands. The tubers are healthier than rice, banana or cassava, and can play an important role in food security. Production is, however, often very low due to various diseases and farmers can struggle to generate sufficient added value. This is where Wageningen comes in.Potato specialist Anton Haverkort travels the world giving advice on how to bring cultivation ...

  • Managing Late Blight of Potatoes and Tomatoes

    Late blight is one of the most serious diseases of potatoes and tomatoes worldwide, resulting in significant yield and quality losses annually. In Alberta, late blight occurs infrequently, but can have devastating impacts in the years when it reaches epidemic levels.  “This disease is caused by a fungal pathogen called Phytophthora infestans,” says Robert Spencer, ...

  • Webinar: Fertility Considerations for Optimal Potato Production

    On Wednesday, March 12, 2014, Dr. Brian Levene, AgroLiquid Specialty Crops Researcher, will join Steve Holland, owner and operator of Holland Agricultural Services, for a free webinar on optimizing potato production for the 2014 season and beyond. With more than two decades experience between them, Levene and Holland, will offer producers insight gained from experience and the industry’s ...

  • China - Netherlands cooperation on improvement of China potato production

    Raising China potato production is of utmost importance. In the coming years a great effort is to be made to meet the increasing demand of potatoes for fresh consumption and for industry. In a joined R&D program Chinese and Dutch research institutes and companies investigated opportunities for improvement on the main topics of potato production. ‘Progress Report China Potato GAP ...

  • Tasmanian Potato Producers Hungry for New R&D

    Tasmanian potato producers have worked up an appetite for new potato research and development (R&D) information, with close to 70 members of the Tasmanian potato industry set to attend a special R&D workshop to be held in Devonport on Wednesday night.   “AUSVEG has received a record number of responses to the potato R&D workshop being held in Tasmania tomorrow ...

  • Rising emissions may double sweet potato size

    Rising levels of carbon dioxide (CO2) in the atmosphere caused by human-driven emissions might lead to larger sweet potatoes, a staple food for many African and Asian countries, research reveals. Sweet potatoes could double in size with the increase in CO2 levels currently forecasted for the end of this ...

  • Arsenic in irrigation water is transferred to crops

    A team of researchers from the University of Valladolid (UVA) and the Salamanca Institute of Natural Resources and Agrobiology (IRNASA-CSIC) has shown that potatoes irrigated with arsenic-rich water contain this element at levels up to 35 times higher than crops on which this water was not used. The scientists have also confirmed the impact of water with high arsenic content on beet, carrot and ...

  • Assessing stressed crops from the sky

    In Peru, the International Potato Center (CIP), Lima, uses drones to aerially assess crop performance under different stresses, such as pests, diseases, drought and frost — all of them widespread phenomena in the Andes, one ...

  • Basic food crops dangerously vulnerable

    In the case of wheat, for instance, as a deadly new strain of Black Stem Rust devastates harvests across Africa and Arabia, and threatens the staple food supply of a billion people from Egypt to Pakistan, the areas where potentially crop and life-saving remnant wild wheat relatives grow are only minimally protected. “Our basic food plants have always been vulnerable to attack from new strains of ...

  • Offering integrated solutions and driving partnerships to promote sustainability in potatoes

    At the 9th World Potato Congress, Bayer CropScience is showcasing its latest innovations and contributions for sustainable potato production. Under the theme ‘Innovating Together for Sustainable Potatoes’ experts from the company will present recent product novelties and new approaches that underline the role of Bayer CropScience as the innovation leader in its field.

  • Soil and crop management and carbon sequestration

    Research results from management scenarios ranging from those in the South Eastern, Great Plains, and Upper Midwest regions of the US and from Italy are reported in the March-April, 2010 issue of the Soil Science Society America Journal. This group of papers originated from the Soil Carbon Sequestration and Greenhouse Gas Mitigation Symposium that was held jointly by the Soil Science Society of ...

  • Scientists find new defence front against the Potato Blight

    In this week 'Nature Plants', scientists from Wageningen University, The Netherlands, and The Sainsbury Laboratory in Norwich, UK, report the identification of a resistance gene that enhances resistance against potato late blight from a South American wild relative of cultivated potatoes. The gene targets elicitin, a conserved protein with an important biological function, making it less likely ...

  • UF/IFAS Finding Could Help Farmers Stop Potato, Tomato Disease

    A University of Florida scientist has pinpointed Mexico as the origin of the pathogen that caused the 1840s Irish Potato Famine, a finding that may help researchers solve the $6 billion-a-year disease that continues to evolve and torment potato and tomato growers around the world. A disease called “late blight” killed most of Ireland’s potatoes, while today it costs Florida ...

  • Alterra and partners to demonstrate the use of brackish water for potato cultivation in Egypt

    A consortium led by Alterra has recently started a project called “Salt TOlerant Potatoes improve water and food security - STOP”. Together with our partners we will extend and test the existing Dacom soil moisture monitoring system with a new salinity sensor. Use of this advisory system will prevent both crop drought and salinity stress, while minimizing water losses. It will enable ...

  • Potato battery could help meet rural energy needs

    The holy grail of renewable energy research may lie in the cooking pot, according to scientists. The search for a cheap source of electricity for remote, off-grid communities, has led to batteries that work on freshly boiled potatoes. One slice of potato can generate 20 hours of light, and several slices could provide enough energy to power simple medical equipment and even a low-power ...

  • Irrigation method saves 50 percent of water needed for potato growth

    University of Florida Institute of Food and Agricultural Sciences researchers have found an irrigation method that uses 50 percent less water than traditional systems to grow potatoes – an important finding for the $131 million-a-year Florida crop. The system is called “hybrid center pivot irrigation.” With this method, about two-thirds of the water used to help grow potatoes is ...
