Research Expands Options for More Sustainable Soybean Production
Publicado em 21 de abril de 2025
Brazil is the world’s largest producer of soybeans and one of the reasons is the incorporation of bio-inputs, microorganisms that promote biological nitrogen fixation. Without this practice, this essential nutrient would have to be supplemented with fertilizer. By managing fertilizer use, Brazilian growers can save an estimated USD 15 billion per year.
The main bio-input used commercially today is bacteria of the genus Bradyrhizobium spp. (rhizobia). In a study supported by FAPESP, [...]

Ancient Maize Samples in Brazilian Caves Suggest the Crop's Domestication May Have Been Completed in South America
Publicado em 09 dezembro 2024Brazilian scientists have determined that ancient specimens of partially domesticated maize (Zea mays, also known as corn) originally from Peruaçu Valley in Minas Gerais state (Brazil) were the farthest from Mexico, the plant's historic center of origin, of any finds made so far. An article describing their research is published in the journal Science Advances. The study was led by researchers affiliated with the University of São Paulo (USP) and EMBRAPA, the Brazilian [...]ver notícia -
Organic Farms Certified by Peers Display Higher Product Diversity
Publicado em 12 agosto 2024In Brazil, a study compared two systems of organic product certification implemented in São Paulo state. One system involves conventional certification by auditors accredited by the Ministry of Agriculture and the National Institute of Metrology, Quality and Technology (INMETRO). The other is peer-to-peer certification. The study, reported in an article published in the journal Organic Agriculture, suggests that peer-to-peer certification adds the virtue of agrobiodiversity to organic [...]ver notícia -
Review article shows key role of Brazil in research on sugarcane for bioenergy
Publicado em 28 novembro 2023Publications on sugarcane have increased exponentially since 2006 worldwide, and Brazil has had more articles published on the topic than any other country in the period, according to a review in BioEnergy Research. The number of articles on the subject averaged about five per year between 1999 and 2006 but had reached 327 by 2021. Brazil has twice as many articles on sugarcane as the United States, which ranks first in the world for scientific publications in general. Brazil [...]ver notícia -
Toxins Are Detected In Samples Of Curd Cheese And Artisan Mozzarella In Brazil
Publicado em 26 maio 2023Strictly speaking, cheese should be completely free of aflatoxins, a class of toxic compounds that are produced by certain molds found in food, and can cause liver damage and cancer. In practice, however, the technology used to produce milk and cheese is unable to guarantee the total absence of aflatoxins, as demonstrated by research performed in several countries. In the latest study conducted in Brazil on this subject, a team of researchers analyzed 28 samples of curd cheese and mozzarella [...]ver notícia -
Mutant strains of Salmonella make infection more aggressive in commercial poultry, study shows
Publicado em 12 abril 2023In Brazil, a group of researchers supported by FAPESP created mutant forms of Salmonella to understand the mechanisms that favor colonization of the intestinal tract of chickens by these pathogenic bacteria and find better ways to combat the infection they cause. An article on the study is published in the journal Scientific Reports. In it, the researchers note that, contrary to expectations, the mutant strains caused more severe infections than wild-type bacteria. In the mutant [...]ver notícia -
Agriculture needs Fresh Approach to Tackle Growing Problem of Insect Resistance to Biopesticides, New Analysis finds
Publicado emInsect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists. For more than 70 years, agriculture's response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests. Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in pest [...]ver notícia -
Researchers analyze performance of bacterium in combating coffee rust
Publicado em 21 dezembro 2022Their research is part basic science, investigating the bacterium's resilience in a hostile environment – coffee leaves – and part biotech, seeing whether the bacterium inhibits the development of a pathogen that causes severe losses to coffee growers. A study supported by FAPESP analyzed the potential of a bacterium for biological control of the fungus Hemileia vastatrix, which causes coffee rust, a major challenge for Brazilian coffee growers. An article on the study is [...]ver notícia -
Review of More Than 1,000 Articles Seeks to Understand How Nanomaterials Affect Plants
Publicado em 17 novembro 2022With the metadata (data generated from the data published in the literature), the authors systematized the knowledge produced collectively to date on the most used nanomaterials, the type of environment to which plants are exposed, the plant organs most exposed to treatments, and the duration of studies. In addition, they calculated the percentages of nanomaterial-based treatments that had positive effects, negative effects and both, as well as those that had no effect on plants. The study [...]ver notícia -
Artificial intelligence helps predict performance of sugarcane in the field
Publicado em 19 outubro 2022October 19, 2022 by Ricardo Muniz, FAPESP A Brazilian study published in Scientific Reports shows that artificial intelligence (AI) can be used to create efficient models for genomic selection of sugarcane and forage grass varieties and predict their performance in the field on the basis of their DNA. In terms of accuracy compared with traditional breeding techniques, the proposed methodology improved predictive power by more than 50%. This is the first time a highly efficient genomic [...]ver notícia
