Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
(Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -

Changes in soil characteristics after six seasons of cereal–legume intercropping in the Southern Pampa
(Elsevier, 2015-04)The Argentine Pampa is one of the most productive agricultural regions in the world, but sole crop management practices have led to soil degradation and losses of soil organic matter. The objective of this study was to ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
(Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -

(2015-04)Este artículo pone en relieve las ideas y los intereses políticos y económicos que condujeron a la reciente institucionalización de la agricultura familiar en la Argentina. Este sector, que fue motor de la primera ... -
Quantifying the impacts of ecological restoration on biodiversity and ecosystem services in agroecosystems: A global meta-analysis
(Elsevier, 2015-04)Landscape transformation due to agriculture affects more than 40% of the planet’s land area and is the most important driver of losses of biodiversity and ecosystem services (ES) worldwide. Ecological restoration may ... -
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ... -
Land tenancy, soybean, actors and transformations in the pampas: A district balance
(2015-06)In Argentina, the recent expansion of agriculture has turned into an extreme process almost completely dominated by soybean. The magnitude and speed of soybean expansion are believed to be the main drivers behind social, ... -
