Résumé traduit : La température moyenne était le facteur climatique dominant influençant la plupart des stades et phases phénologiques du soja. Les dates de semis retardées et l'utilisation de cultivars de plus longue durée sont des adaptations de gestion que les agriculteurs ont utilisées pour s'adapter aux changements climatiques survenus au cours des dernières décennies et qui peuvent continuer d'être utilisées. Ces résultats indiquent que les agriculteurs ont une fenêtre de semis plus large au printemps et peuvent sélectionner des cultivars avec une longue saison de croissance et une tolérance au gel pour atténuer les effets néfastes d'un futur climat plus chaud. – guatemalt

HORTICULTURAE 30/12/16 Trends of Soybean Yields under Climate Change Scenarios. Soybean is a very important crop, cultivated mainly as stock feed for animal production, but also for other uses such as biodiesel.

HORTICULTURAE 30/12/16 Trends of Soybean Yields under Climate Change Scenarios

Brazil is the second largest producer of soybeans, and the main exporter. About 10% of total Brazilian production is aimed for biodiesel production. The aim of this work was to assess the impact of climate change scenarios on soybean yield and evaluate two simple adaptation strategies: cultivar and planting date. Tests were done for soil profiles from two important producing regions: Chapecó-Red Oxisol, and Passo Fundo-Rodic Hapludox. Two commercial soybean cultivars (CD202 and CD204) and seven regional circulation models (RCM) were used. ►▼ Show Figures Figure 1 This is an open access article distributed under the Creative Commons Attribution License which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

INVESTIGATE MIDWEST 21/09/16 Study: Climate change likely to lead to decreased soybean yields. The negative effects of climate change on Illinois soybean farmers will likely be greater and come sooner than originally thought, new research at the University of Illinois has found.

The study, led by crop sciences professor Andrew Leakey, contradicts the widely held belief that increased carbon dioxide in the atmosphere will boost the yields of crops. Researchers found that in ideal growing conditions, carbon dioxide boosts crops’ yield, but in years of drought, the damage offsets those benefits. “The expectation before was actually the opposite. In wet years, you would get some benefit. In dry years, you would get even more benefit from the CO2,” Leakey said.

Courtesy UW–Madison CALS. Listen to Shawn Conley talk about this story. Even during a good year, soybean farmers nationwide are, in essence, taking a loss. That’s because changes in weather patterns have been eating into their profits and taking quite a bite: $11 billion over the past 20 years. This massive loss has been hidden, in effect, by the impressive annual growth seen in soybean yields thanks to other factors. “We are still making yield gains because of breeding and other strategies, but those numbers aren’t as big as they could be,” says lead author Shawn Conley, a UW–Madison agronomy professor and UW-Extension soybean and wheat specialist.

Averaging the data across the United States, researchers found that soybean yields fell by around 2.4 percent for every one-degree rise in temperature. These divergent responses have to do with historical norms. —Caroline Schneider.
