  • Intercropping `boosts maize yields by 50 per cent`

    Growing leguminous trees on maize farms — a form of agroforestry — can boost and stabilise maize yields, a 12-year study in Malawi and Zambia has found. The researchers behind the study, from the Kenya-based World Agroforestry Centre ...

  • Earthworms decompose GM maize

    Pest-resistant genetically modified (GM) maize makes up an increasing proportion of maize grown commercially in the EU. A new study shows that earthworms may help break down the toxins produced by GM maize. GM maize (Bt-maize) plants are engineered to produce 'cry' proteins that are toxic to the European corn borer, a major insect pest responsible for corn crop losses. Recent studies have shown ...

  • Compost made by worms from livestock manure yields benefits when applied to maize

    Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system. As intensive agriculture and livestock production both increase, unique problems emerge. Heavy use of ...

  • 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 ...

  • Sustainable silage maize farming requires earlier varieties

    Dutch silage maize farmers can increase their yield in the long term by using earlier varieties. This was the conclusion reached by maize scientists at Wageningen UR based on many years of practical cultivation tests. The use of earlier varieties increases the chance that the maize will ripen properly and ensures better (soil) conditions for harvesting. Moreover, it would provide more space for ...

  • US–Nepal hybrid maize project runs into criticism

    Uncertainty hangs over a proposed partnership between US and Nepalese scientists to promote hybrid maize in the Himalayan country, after the project sparked local concerns over the potential loss of traditional local varieties and weak biotechnology regulation. The pilot project of the US Agency for ...

  • Method to differentiate open pollinated varieties of maize developed

    Open pollinated varieties of maize are going to be easier to distinguish from each other, thanks to scientists at the International Maize and Wheat Improvement Center (CIMMYT) in Africa and Mexico. They have developed a new technique to differentiate the genes of one open pollinated variety from another, particularly important to African farmers, most of whom do not plant hybrid varieties. The ...

  • Warming Threatens to cut Crop Yields

    Projecting the impact of climate change on global food production is no easy task. A warming climate might result in better crop yields in one region, but cause drought and crop failure in another. A new US study, published in the journal Environmental ...

  • Burundi set to embrace hybrid maize seeds

    Farmers in Burundi are set to benefit from new high-yielding, fast-maturing hybrid maize seeds that are also resistant to maize streak virus. The varieties are being tested by the Burundi Institute of Agronomic Sciences (ISABU) and should be available to farmers in September. Two seed companies, Pannar and Naseco, based ...

  • Patents fail to boost crop yields

    Policies that secure intellectual property rights (IPRs) for agricultural innovations often fail to encourage technology transfer to developing countries or increase crop yields, a study shows. “Intellectual property rights are ...

  • Impact of volunteer GM maize on conventional crops is low

    A recent EU-supported study has analysed the development of volunteer or 'rogue' GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU's threshold of 0.9 per cent for incidental GM content. Scientific data on the role of maize volunteers on cross-pollination is limited. The most detailed studies have been conducted in ...

  • Crop yields stall in China, India

    China and India, the world's two most populous countries, are beset by stagnation in the production of staples like rice, wheat, soybean and maize (corn), says a new study on crop yield growth. Based on statistics from around the world during the 1951– 2008 period, the study 'Recent patterns of crop yield growth and stagnation', says that for some crops in China and India the spatial extent ...

  • Warming threatens to cut crop yields

    Projecting the impact of climate change on global food production is no easy task. A warming climate might result in better crop yields in one region, but cause drought and crop failure in another. A new US study, published in the journal Environmental Letters, assesses the odds of a major slowdown in global food production over the next 20 years. Overall, the study’s authors say, the ...

  • 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 ...

  • Pigeon pea genome sequence could boost yields

    More than a billion people could soon benefit from improved yields of the important drought-resistant crop pigeon pea now that its genome has been sequenced by a global partnership. The sequence, published online in Nature Biotechnology last week (6 November), should cut the time it takes to develop higher-yielding pigeon pea varieties from the 6–10 years required for traditional breeding ...

  • Microbes `cheaper, fairer` for boosting yields than GM

    Adapting microbes that dramatically increase crop yields while reducing demand for fertilisers and pesticides through selective breeding or genetic engineering could be cheaper and more flexible than genetically modifying plants themselves, says an author of a report. Microbes, such as beneficial bacteria, fungi and viruses, could be ...

  • 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 ...

  • Banana compost could boost crop yields, a study finds

    Using old banana trees to make compost may help boost crop yields while cutting down water and fertiliser use, according to an Egyptian researcher. Banana-based fertiliser could cut about 20 per cent of the water used in irrigating maize and lead to better yields and improved soil properties — such as availability of ...

  • Satellite data plus conservation equals better crop yields

    Combining remote sensing technology  with water and soil conservation techniques can help raise crop yields in South Asia, scientists have reported. Satellite data can help identify specific problems on farmlands ...
