  • Improve crop yield by removing manure solids

    Manure has long been used as a crop fertilizer, but the challenge of finding an efficient use of the nutrients found in manure is ever present. The ratio of nitrogen to phosphorus in manure is low in relation to the nutrient needs of most crops. Therefore, crops tend to be overloaded with manure to meet the nitrogen requirement of agricultural crops, but the excess phosphorus from the process can ...

  • 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 ...

  • Yield projections for Switchgrass as a Biofuel Crop

    While scientists have conducted numerous studies on production of biomass from biofuel crops, such as switchgrass, no one has yet compiled this information to evaluate the response of biomass yield to soils, climate, and crop management across the United States. A team of researchers from Oak Ridge National Laboratory and Dartmouth College published just such a study in the July-August 2010 ...

  • 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 ...

  • Revolutionary technology improves lettuce harvest yields

    BiOWiSH™, a breakthrough enzyme technology, has boosted hydroponic lettuce weights by up to 30% at harvest time, according to results of a recent trial. The new technology was adopted during multiple full growing cycles at the Glenorie Hydroponics lettuce farm in New South Wales, Australia. The results showed BiOWiSH™ treated lettuce were 17% to 30% heavier at harvest time for red and ...

  • Pest ants help to improve Indonesian cocoa yields

    Native ants living in cacao trees in Indonesia that are often seen as pests in fact seem to boost their yields, a study suggests. Scientists from Germany, Indonesia and Sweden studying how ant communities affect cocoa yields in Sulawesi found that trees with abundant native ants (Dolichoderus sp.) produced the best yields. In contrast, the yields of cacao trees where ants were excluded were 27 ...

  • Improving wheat yields for global food security

    With the world’s population set to reach 8.9 billion by 2050, CSIRO scientists are hunting down and exploiting a number of wheat’s key genetic traits in a bid to substantially boost its grain yield. The rate of wheat-yield improvement achievable through conventional plant breeding and genetic engineering alone is not fast enough to compete with a rapidly growing global ...

  • Straw covering on soil can increase crop yields and improve the efficiency of water use

    Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season. In north-western China, ...

  • Using GPS sensors to economize on irrigation while increasing crop yields

    Domosys Corporation, a leading provider of Power Line Communication (PLC) technology, has announced that Lindsay Corporation, a leading provider of irrigation systems and infrastructure products, has selected Domosys’ PowerBus™ RHINO Technology to significantly improve its irrigation systems. Lindsay’s irrigation system, also called a center pivot, uses Domosys’ PLC technology and products to ...

  • Herbicide reduction can preserve crop yields as well as biodiversity benefits of weeds

    Pesticide-sparing approaches to farming do not have to compromise on crop yields, new research suggests. A study that explored the impact of reduced herbicide use across a variety of different farming contexts found that herbicideefficient systems could be just as productive as conventional systems — and more so than organic systems — whilst having other important environmental ...

  • 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 ...

  • Using rotation crops to improve soil quality

    Soil quality issues are being researched within two crop rotation experiments that started in 1994 at Narrabri. They compare several crop rotations that include or exclude legume phases. The data presented here relate to the most recent 2-year cycles of these experiments. Following cotton harvest at the end of the previous cycle, rotation crops are sown (winter cereal, faba beans (grain) or vetch ...

  • Where is your soil water? Crop yield has the answer

    Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

  • Crop models help increase yield per unit of water used

    Crop water use efficiency (WUE, or yield per unit of water used), also known as crop water productivity, 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 ...

  • 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 ...

  • 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 ...

  • Soil biodiversity reduces nitrogen pollution and improves crops’ nutrient uptake

    Increased soil biodiversity can reduce nitrogen pollution, improve nutrient uptake by plants and even increase crop yields, new research suggests. The two-year study found that levels of nitrogen leaching from soil with an abundant soil life were nearly 25% lower than for soil with a reduced level of soil life. Practices which enhance soil biodiversity such as reduced tilling, crop rotation and ...

  • High-yield crops have curbed agricultural land expansion, but care needed to avoid negative biodiversity effects

    The widespread use of higher-yielding improved varieties of crops as part of the Green Revolution’ has averted the conversion of between 18 to 27 million hectares of forests, woodlands and pastures in the period 1965 to 2004, according to a recent study. However, its authors caution that the relationship between these crops and land use change is complex, and good governance is needed to ...

  • Strategic organic matter throughput helps to build soil carbon and boost crop yields

    Potential improvement in crop yields and reduced greenhouse gas emissions were among the benefits of increased soil organic matter throughput according to the findings of a project funded by growers and the Australian Government through the Grains Research and Development Corporation (GRDC) and the Victorian Department of Primary Industries (DPI). The relationships between organic matter inputs ...
