  • Statistical analysis can estimate crop performance

    Scientists at Rothamsted Research, United Kingdom, in collaboration with the International Center for Agriculture Research in the Dry Areas (ICARDA), Syria have developed a method of accounting for spatial trend in single crop field trials. Spatial trend refers to the variations in crop yield and other characteristics observed when repeating this single crop field trial.   Usually plant ...

  • Crop performance matters when evaluating GHGs

    Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional ...

  • Energy crops and their environmental implications

    Interest in producing cellulosic ethanol from renewable energy sources is growing. Potential energy crops include row crops such as corn, perennial warm-season grasses, and short-rotation woody crops. However, impacts of growing dedicated energy crops as biofuel on soil and environment have not been well documented. This review article looks at the impacts of growing warm-season grasses and ...

  • The future of cover crops

    Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown that time and money are the two primary reasons why farmers are hesitant to adopt the technique. Developing innovative and cost-effective crop cover systems could increase the ...

  • 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 ...

  • Choice of winter cover crop mixture steers summer crop yield

    Scientists from Wageningen University & Research demonstrate that the productivity of a next main crop can be manipulated through the choice of species in a preceding winter cover crop mixture. They report their latest findings in the Journal of Applied Ecology of 2nd of June. With their publication, the scientist agree with recommendations of FAO to included cover crops in rotations, on top ...

  • New crop sprayer is kinder on the environment

    An EU project has developed a new crop spray system for orchards that is precise, efficient and safer for the environment. It sprays pesticides according to the needs of the crop and local environment, and can reduce spray drift by up to 80 per cent. Preliminary field tests conducted in Poland have demonstrated its effectiveness. The EU has adopted a framework directive on the sustainable use of ...

  • Crop Protection China News 1002

    Crop Protection China News 1002 International economic crisis not only brings great challenges to China’s pesticide industry but also drives the industry to accelerate in industry integration to cope with intense competition. With the governmental policy supports, China’s pesticide industry is ...


  • Soil phosphorus in an organic cropping system

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. (For one overview discussion of phosphorus, see Phosphorus Famine: The Threat to Our Food Supply in the June 2009 Scientific American.) Organic farming with low phosphorus  inputs can result in deficient levels of plant-available phosphorus (available-P).A group of researchers from ...

  • Ohio’s 2015 Soybean Crop Performance Trials Reveal Higher than Expected Yields

    Despite the heavy rains that hit the region early during the growing season this year, soybeans in the majority of test plots planted by researchers with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University still managed to beat expectations. In fact, in four of the six test sites for the 2015 Ohio Soybean Performance Test, soybeans averaged over 70 bushels ...

  • Ohio’s 2015 Wheat Crop Faced Tough Year

    Growers wondering how this year’s historic rains have impacted wheat now have proof that it has indeed been a tough year for the crop, according to the results of the 2015 Ohio Wheat Performance Test. The test results are offered by researchers with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University and can be viewed at  ...

  • In-crop nitrogen key to summer sorghum yields

    With the summer cropping season on our doorstep, growers are weighing up their planting options against the market, seasonal conditions and gross margin calculations. For many the summer cropping rotation will include sorghum and maximising crop yield and profitability will be a key driver of all pre-plant and in-crop agronomic decisions. Recent research funded by the GRDC, Queensland Alliance ...

  • Forage crop promising as ecologically friendly ornamental groundcover

    A new, ecologically friendly groundcover for warm-weather landscapes is on the horizon. Rhizoma peanut, a warm-season perennial native to South America, has been used almost exclusively as a forage crop in the United States since the 1930s, but a study in the July HortScience says the perennial has potential as an ornamental groundcover or turf alternative. "Rhizoma peanut is grown in U.S. ...

  • Potentially harmful effects of nanomaterials on soybean crops

    A new study has examined contamination of fully grown soybean plants by two nanomaterials – nano-cerium oxide and nano-zinc oxide. The results could be concerning, as they indicate that the nanomaterials are absorbed by plants, possibly affecting growth, yield, and the fixation of nitrogen in soil, an important ecosytem service. With the rapid expansion of nanotechnology, there is ...

  • The dire need to support ‘orphan crop’ research

    In spite of debate over its definition, the term ‘orphan crops’ refers to crops that are under-researched and underfunded due to their limited importance in the global market. These include cereals, legumes, vegetables, root crops, fodder crops, oil crops, fibre crops and ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • Hawaii is genetically engineered crop flash point

    You can trace the genetic makeup of most corn grown in the U.S., and in many other places around the world, to Hawaii. The tiny island state 2,500 miles from the nearest continent is so critical to the nation's modern corn-growing business that the industry's leading companies all have farms here, growing new varieties genetically engineered for desirable traits like insect and drought ...

  • Crop residues provide valuable protection for soil

    Removing wheat and sorghum crop residue after harvest, such as stalks, stubble and leaves, may cause more harm than good according to new research. Results indicate that removing residue can increase nutrient and sediment levels in water runoff, and decrease organic carbon stored in the soil. Crop residue left after harvest performs several ecosystem services. In particular it protects the soil ...

  • “Biofortification” boosts nutrients in Africa’s staple crops

    Whether a bowl of rice or a piece of bread, staple foods provide millions of poor people around the world with a source of basic sustenance day in and day out. Now, a new technology promises to make these foods-which provide calories but do not always contain enough of the micronutrients required for good health-more nutritious. People who intake insufficient amounts of iron, zinc, and vitamin A ...
