  • Simulating Agricultural Climate Change Scenarios using Controlled Growth Chambers

    Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2   Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change ...

  • Crop water use efficiency

    Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...

  • 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 ...

  • WSSA Scientists Stress the Importance of Early Response to Invasive Weeds

    Over the past decade, dozens of “early detection, rapid response” initiatives have been launched by states to keep invasive species from devastating natural habitats and damaging our economy. Many of these programs use mobile apps and online databases to revolutionize how we collect data on harmful invaders – making it easier to map infestations and to share information broadly. But ...


  • A long history but slow uptake of drought-tolerant crops

    In his opinion article, Drought-tolerance: a learning challenge for poor farmers, Travis Lybbert points to a growing interest in drought-tolerant (DT) crops in recent years, largely motivated by impending climate change. In fact, research and development ...

  • 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 ...

  • Moss holds the key to crops surviving droughts

    Scientists from the University of Leeds, with colleagues from Germany, Japan and the US, have unravelled the genome for Physcomitrella, the first non-flowering or 'lower' plant to be sequenced. The group have published their findings in the journal Science. Researchers will now be able to study the moss’s DNA to identify which genes enable the plant to survive environmental stress. They then ...

  • India boosts budget for science, innovation, crops

    Indiahas hiked funds for its ministry of science and technology by 20 per cent in its 2013-14 annual budget, with major initiatives in the agriculture sector and support for grassroots innovations. India’s finance minister Palaniappan Chidambaram allocated US$ 1.15 billion (62.7 billion rupees) for the ministry of science ...

  • 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. ...

  • Keeping tabs on the next generation of transgenic crops

    A team of government and university crop scientists from across Canada has developed a scientific framework for monitoring the release of second-generation genetically modified crops. The framework is designed to assess the risks of novel genes entering wild populations. First-generation genetically modified (GM)/transgenic crops with novel traits have been grown in a number of countries since ...

  • Biofuel and crop research grows by AUS$1.6m

    The research team will identify the genes associated with key plant properties responsible for growth, flowering and grain-filling in grasses. They will use the advanced robotic and imaging plant research tools of the Australian Plant Phenomics Facility (APPF) to conduct the research. The US Department of Energy (DOE) has recognised the unique, world-class capability that the APPF affords by ...

  • New crop of plant scientists emerges at CSIRO

    Under the CSIRO Plant Industry Summer Student Program, 17 students are engaged in a range of important agricultural research projects designed to discover, for example, how high temperatures affect crops and the genetic bases of crop development. The Program, which runs from 6 December to 11 February, provides university students with real insights into the day-to-day working lives of some of ...

  • Pakistan needs a new crop forecasting system

    Pakistan's outdated crop yield forecasting system needs a revamp, says Ibrar ul Hassan Akhtar. Like most developing countries, Pakistan is staring at the spectre of food insecurity, with its food production out of sync with population growth. The food availability scenario is further ...

  • Weather Fluctuations Impact Soybeans Less Than Other Field Crops

    From freezing temperatures and snow flurries to sunny, 80-degree days in a span of a week — if this type of strange weather continues, growers across Ohio want to know, will this have a negative impact on soybean crops? Not really, according to a field crops expert in the College of Food, Agricultural, and Environmental Sciences at The Ohio State University.   Laura Lindsey, a soybean ...

  • Patches of flowers boost pollinator diversity and lead to higher crop yields

    Falling levels of insect pollination are causing declining yields of important agricultural crops. However, new research from South Africa now indicates that planting small patches of native flowers in agricultural fields can be a profitable and sustainable method of increasing pollination and yield. Insect pollination is a vital ecosystem service as animal-pollinated crops form an ...
