  • Maize seedlings predict drought Tolerance

    Scientists have developed a new method for measuring drought tolerance in maize. By comparing the shoot-to-root ratio in seedlings stressed by low water, scientists can predict whether a plant has the right mix of genes for adapting to drought conditions. The ideal drought-resistant maize should have a higher ratio of root surface area compared to leaves and stems. Developing enough adult plants ...

  • Vermicompost leachate improves tomato seedling growth

    Worldwide, drought conditions, extreme temperatures, and high soil saline content all have negative effects on tomato crops. These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are ...

  • 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 ...

  • GM maize contaminates non-GM crops in Uruguay

  • 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 ...

  • Neonicotinoids: may reduce crop yields by poisoning insects that eat slug pests

    Beetles that are helpful to farmers can be poisoned if they feed on slugs that have eaten crops treated with neonicotinoids, a new study reports. The slugs themselves are not harmed by neonicotinoids. In American field trials, researchers found that plots planted with neonicotinoid-treated soybeans contained more slugs, fewer beetle predators and had 5% lower yields. The insecticide may be ...

  • Light-emitting Diode Sole-source Lighting Effective in Bedding Plant Seedling Production

    In northern latitudes, producers of bedding plants depend on supplemental lighting during the late winter and early spring growing seasons. Unfortunately, these peak times for young plant production are also the darkest. Researchers have determined that a minimum amount of photosynthetic light (daily light integral; DLI) is necessary to produce high-quality young plants in greenhouses. In ...

  • GM seeds can remain in fields longer than previously thought

    Despite management practices designed to reduce the risk of genetically modified (GM) volunteer plants setting seed, new research shows that rogue GM plants occur in fields which were planted with GM oil seed rape 10 years earlier. Volunteer plants (plants that have not been planted deliberately) arise because some seed is spilled during harvest and remains in the field to germinate in a ...

  • Late Corn Better Than Blighted Corn

    Growers whose corn crops were harmed by excessive rain in April and May likely will have enough growing days left in the season if they replant in the next two to three weeks, according to an Ohio State University agronomist. “If they replanted soon, it would probably be much better than to have a poor stand,” said Peter Thomison, an agronomist with Ohio State University Extension, ...

  • UF/IFAS research may give new hope to expanding avocado production

    Findings from new University of Florida research may lead growers to produce avocados in the Indian River region of Florida, an area where the citrus industry has fallen on hard times. The research comes from a dissertation by Cristina Pisani, who recently completed her doctorate in horticultural sciences at the University of Florida Indian River Research and Education Center near Fort Pierce. ...

  • ARS scientists develop self-pollinating almond trees

    Self-pollinating almond trees that can produce a bountiful harvest without insect pollination are being developed by Agricultural Research Service (ARS) scientists. This is good news for almond growers who face rising costs for insect pollination because of nationwide shortages of honey bees due to Colony Collapse Disorder (CCD) and other factors. ARS geneticist Craig Ledbetter, at the agency’s ...
