  • Traditional rice helps beat soil salination

    Rohana Rosairo has hung a sprig of paddy rice over his front door, a good omen for prosperity from the first harvest he reaped a few weeks ago from a long unused field. Rosairo's field, across a dirt track from his home, was just a mass of weeds until April when he cleared the plot and planted seed paddy. 'My father used to grow rice here, but he stopped a long time ago,' he said. High salinity ...

  • Some but not all plants can defend themselves against disease on saline soil

    Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

  • Biodiesel Crop of the Week: Pongamia Pinnata

    Pongamia is an ancient tree that is native to India. It is frost tolerant, but not freeze-proof. It is also happens to be a legume, which is at the heart of what makes the business model so interesting. The tree yields a generous annual nut crop that is harvested with conventional shakers, such as those used by almond and other nut growers. That seed has approximately a 40 percent oil content ...

  • Plant bank to preserve biodiversity of Pacific crops

    The giant swamp taro, the orange-fleshed Fe'i banana and a coconut that grows to half a metre in length are among the native crop species to be saved in a major project that has begun across small islands in the Pacific. The Centre for Pacific Crops and Trees (CePaCT) is coordinating the project in which 1,000 unique varieties of staple fruit and vegetables from 7,500 Pacific islands are being ...

  • Desert bacteria could help boost crop yields

    Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study.   Scientists from the United Arab Emirates [UAE] have isolated local salt- and drought-tolerant strains of Rhizobia, soil bacteria that fix nitrogen when they become established ...

  • Genetic change could make crops thrive on salty soils

    Scientists have genetically modified plants to tolerate high levels of salt — offering a potential solution to growing food in salty soils. The researchers inserted a gene to remove salt — in the form of sodium ions — from water taken up by the plant before it reaches the leaves, where it does most damage. The research was published in The Plant Cell this month (7 July). High salinity reduces ...

  • Maintaining food crop diversity: an interview with Gary Paul Nabhan

    Guest author Fred Bahnson interviewed Gary Paul Nabhan, a lecturer, food and farming advocate, folklorist, and conservationist who lives and farms in the U.S. Southwest. Nabhan discusses his new book, the future of agriculture, and how 1,400-year-old Lebanese farming techniques influence his land ethic. Tell me about your latest book, Where Our Food Comes From-Retracing Nikolay Vavilov's ...

  • Ancient crops preserved for future generations in Arctic seed vault

    Varieties of one of the world's most important staple crops will be stored for perpetuity deep in the Arctic ice today. José Graziano da Silva, Director-General of the Food and Agriculture Organization of the United Nations (FAO) is joining scientific experts and delegations from Peru, Costa Rica and Norway to witness a ceremony here this afternoon that will help to preserve these ...

  • Strategic organic matter throughput helps to build soil carbon and boost crop yields

    Potential improvement in crop yields and reduced greenhouse gas emissions were among the benefits of increased soil organic matter throughput according to the findings of a project funded by growers and the Australian Government through the Grains Research and Development Corporation (GRDC) and the Victorian Department of Primary Industries (DPI). The relationships between organic matter inputs ...

  • Arcadia Receives $4.5 Million Grant from USAID to Develop Salt-Tolerant Rice and Gather Greenhouse Gas Emissions Data from Nitrogen Efficient Crops

    Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, today announced that it has been awarded a 5-year, $4.5 million grant from the U.S. Agency for International Development (USAID) to develop salt-tolerant rice and measure greenhouse gas emissions from ...

  • Groundwater extraction for agriculture increases salt levels in Spanish coastal wetland

    Around 20% of all species found in a Spanish coastal wetland could be affected by increasingly salty water as seawater intrudes into the groundwater system as a result of groundwater being withdrawn to irrigate crops. This is the conclusion of a recent study which used a Life Cycle Impact Assessment approach to characterise the ecological damage in the wetland as a result of changes in ...

  • Helping canneries make better use of leftover water

    With the help of a well-stocked kitchen cupboard, a can opener, and a microwave oven, a steaming-hot bowl of your favorite tomato soup can be ready to savor in just minutes. For decades America's canneries have helped make soups—as well as vegetables, fruits, juices and other familiar foods—more convenient for us to enjoy. Now, Agricultural Research Service (ARS) scientists are helping canneries ...

  • Award for Quinoa project

    The Wageningen UR project 'Salt tolerant Quinoa for food in China, Vietnam and Chile' has received a major prize. The quinoa project is one of the winners of the Securing Water for Food Grand Challenge. The prize is awarded to researcher Robert van Loo during the WWW in Stockholm. In agricultural lands impacted by high salinity, smallholder farmers realized lower-than-average yields and ...

  • Simulated Seawater Flooding Decreases Growth of Vegetable Seedlings

    Crop production in coastal areas is threatened by seawater intrusion, which increases soil salinity. Excessive salinity in soil and irrigation water, in combination with waterlogging, can significantly affect the growth and quality for agricultural crops, especially those vegetables that are sensitive to salinity. A new study determined salt-tolerant vegetable seedlings for coastal area ...

  • New plant varieties developed to thrive despite climate change

    Nuclear technology is helping scientists unmask the hidden potential in plants, allowing plant breeders to develop new crop varieties that can withstand external stress such as drought, often brought about by climate change. Experts believe that climate change will affect the suitability of land for different types of crops, livestock, fish and pasture. It will also have an impact on the health ...

  • Salt-tolerant wheat a breakthrough for better yields

    Australian scientists have successfully carried out field trials of a salt-tolerant durum wheat, boosting grain yield by 25 per cent in salty soils. Durum is one of the most widely grown cereals in the world, but in saline soils it is vulnerable to salt build-up in the leaves, which can hinder growth and reduce yields, threatening food security. The researchers at the University of Adelaide ...

  • 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 ...

  • Chile, India link up for rural development

    Chile and India will work together to promote agricultural innovation and explore the potential of information and communication technologies (ICTs) in improving rural livelihoods. The MS Swaminathan Research Foundation (MSSRF) signed an agreement on agricultural cooperation with Chile's Foundation for Agricultural Innovation (FIA) in Chennai last month (20 March). MSSRF chairman M. S. ...
