  • Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures

    Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

  • From electronic noses to invasive bees, 15 surprising trends for 2017

    What should we be thinking about when we think about the future of biodiversity, conservation and the environment? An international team of experts in horizon scanning, science communication and conservation recently asked that question as participants in the eighth annual Horizon Scan of Emerging Issues for ...

  • Changing climate changes soils

    Varied predictions for soil organic matter as climate changes The hottest months. The snowiest winters. Catastrophic floods and droughts. Climate change impacts lives across the world in drastic and unpredictable ways. This unpredictability also extends to the more subtle – yet still important – effects of climate change. For example, it is ...

  • DACS ventilation system for poultry production - Case Study

    Emmanuel Destrijker from Plessisville, Quebec in Canada, is confident that he made the right choice when buying a DACS ventilation system for his second house for layers. It can be challenging to ventilate properly in a house with cages, but the DACS system has now been in operation for five years and it surely has passed the test. The choice was easy “After five years in ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • Emergence of polymer-coated corn and soybean influenced by tillage and sowing date

    No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

  • Cooking under the sun

    A $6 cardboard box that uses solar power to cook food, sterilise water and could help 3 billion poor people cut greenhouse gases, has won a $75,000 prize for ideas to fight global warming.The 'Kyoto Box', named after the United Nations’ Kyoto Protocol that seeks to cut emissions of greenhouse gases, is aimed at billions of people who use firewood to cook.The cooker uses the greenhouse effect to ...

  • Sowing and flowering delays can be an efficient strategy to improve coexistence of genetically modified and conventional Maize

    The coexistence between genetically modified (GM) and non-GM maize (Zea mays L.) fields is subjected to regulation in several countries. A strategy to reduce cross-pollination from GM to non-GM fields was evaluated, on the basis of reducing the flowering coincidence by sowing at separate times. The trial included narrow plots in which transgenic maize was sown before, simultaneously, and after ...

  • Characterization of selected nutrients and bacteria from anaerobic swine manure lagoons on sow, nursery, and finisher farms in the Mid-South USA

    Received for publication October 31, 2008. Swine (Sus scrofa domestica) production in the Mid-South USA comprises sow, nursery, and finisher farms. A 2007 packing plant closure started a regional shift from finisher to sow and nursery farms. Changes in manure stored in lagoons and land-applied as fertilizer were expected but were unknown because nutrient and bacterial levels had not been ...

  • Critical Operations Go Under Cover

    For a number of years, composting facilities have been using fabric structures to house finished compost screening, soil blending and product storage. They’ve also employed the structures to cover or fully enclose feedstock receiving and mixing. And some have gone as far as to put active composting operations inside fabric buildings. “More and more facilities are putting in fabric ...

  • Effect of sowing year and seedbed type on yield and yield component in bambara groundnut (Vigna subterranea (L) Verdc) in woodland savannahs of Cote d`Ivoire

    Bambara groundnut (Vigna subterranea) is one of the most promising food legumes in Africa, due to its agronomic and nutritional potential. To take advantage of these attributes, several research programmes gathering agronomic and genetic ...

  • Consolidation Behavior of Clayey Soils Under Radial Drainage

    For Barron´s degree of consolidation, Ur, versus the time factor, Tr, relationship for soils undergoing consolidation with radial drainage for the equal vertical strain condition, a simple method has been developed to determine the value of the coefficient of consolidation with radial drainage, cr. Theoretical log10(d2e/t) versus Ur curves where de is the diameter of influence and t is the real ...

  • Valuation and Management of Fishing Resources Under Price Uncertainty

    The traditional expected-net-present-value methods cannot properly capture the management flexibility and strategic value aspects of a fishery, and may understate its value. Instead, this paper develops a Real Options model to conceptualize and evaluate fishery exploitation flexibility. Specifically, general models to value the opportunity to either exploit or invest in a fishery are presented. ...

  • Bank shares restore under recent industry bailouts

    This paper structures ten effective implications/lessons of the most recent bank bailouts of 2007-2009 in the Western economy model when analysing actual shareholders' value retrenchment or growth opportunities. The author finds that recent bank bailouts relate to: global bailout interconnections, economic downturn and liquidity boost, abnormal returns, efficiency recovery, evade social costs, ...

  • Lessons learned from potato growers down-under

    Andy Alexander, specialist potato consultant and agronomist, has provided advice across the UK and Australia for over 35 years, and has travelled to the southern continent over 17 times. He explains how adapting to change in a volatile climate has been key to success for growers in Australia, and what lessons UK growers can take from this. “My role is to provide business ...

  • Nitrogen fixation of Sulla under Mediterranean conditions

    Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

  • Tiller contribution to spring wheat yield under varying seeding and nitrogen management

    Hard red spring wheat (HRSW) (Triticum aestivum L.) grain yield is comprised of the combined production of the main stem and tiller spikes. Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions from 2003 to 2005 to determine tiller development and the relative contribution of main and tiller wheat spikes to final grain yield under varying cultivar, ...

  • Climatic and genotypic effects for grain yield in maize under stress conditions

    Climate change is expected to affect agriculture. Yield stability across environments is a critical breeding goal when dealing with unstable climate and input reductions in farming systems. The objective of this study was to determine climatic and genetic factors contributing to genotype (G), environment (E), and genotype x environment (GE) variability for maize (Zea mays L.) grain yield under ...
