(FLACSO Ecuador, 2018)En el presente artículo se reconstruyen históricamente los territorios periurbanos de Córdoba, con foco en los destinados a la producción hortícola para suministro de la ciudad, sistematizando investigaciones y ... -
Regional model for nitrogen fertilization of site-specific rainfed corn in haplustolls of the central Pampas, Argentina
(Springer, 2011-12)In semi-arid regions, soil water and nitrogen (N) are generally limiting factors for corn (Zea mays L.) production; hence, implementation of appropriate N fertilization strategies is needed. The use of precision agriculture ... -
Rentabilidad de la agricultura de precisión: estimación de márgenes netos del cultivo de maíz con dosis fijas y variables de insumos
(Asociación Argentina de Economía Agraria, 2019-10-20)En el mundo surgen continuamente nuevas y mejores tecnologías de agricultura de precisión; éstas son expuestas a diversos tipos de ensayos y pruebas para demostrar su impacto productivo, pero raras veces se evalúan desde ... -
Resprouting increases seedling persistence likelihood after fire in a semelparous bamboo species
(Elsevier, 2020-08-18)Chusquea culeou is a semelparous bamboo species which dominates the understorey of temperate forests and shrublands of Patagonia, South America. After the massive flowering, seeding and subsequent die-off, it provides an ... -
Retencion y degradación de glifosato en mezclas de rastrojo de maíz y soja con suelo
(2014-12)Se estudió el comportamiento de 14C-glifosato en la zona de transición rastrojo-suelo, en cuatro sitios y dos secuencias de cultivo: monocultivo de soja (Glycine max (L) Merr), y rotación soja-maíz (Zea mays L). La ... -
Retention and redistribution of biological legacies generate resource sinks in silvopastoral systems of Arid Chaco forests
(Springer, 2019-07-11)Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promoting ... -
Row spacing and growth habit in peanut crops : effects on seed yield determination across environments
(Elsevier, 2022-01)Narrowing row spacing was expected to improve peanut crop performance, but the responses varied depending upon the evaluated environment and the growth habit of the plant. To clarify apparent inconsistencies, two cultivars ... -
Scale-dependent effects of conspecific flower availability on pollination quantity and quality in an invasive shrub
(Springer, 2018)Pollen limitation can strongly influence reproduction of pollinator-dependent plants. Flower abundance can affect pollination ‘quantity’ and ‘quality’ due to its influence on pollen availability and foraging patterns of ... -
Screening of the Argentinean INTA peanut core collection with a molecular marker associated with resistance to Sclerotinia minor Jaggar
(2020-07-10)Cultivated peanut, the third most important oilseed in the world, is consistently threatened by various diseases and pests. Sclerotinia minor Jagger (S. minor), the causal agent of Sclerotinia blight, is a major threat to ... -
Seed yield determination of peanut crops under water deficit: Soil strength effects on pod set, the source–sink ratio and radiation use efficiency
(Elsevier, 2008-06-10)Peanut (Arachis hypogaea L.) production in Argentina is affected by frequent and unpredictable periods of water deficit that usually overlap the critical period for pod set of early sown crops. An indirect effect of water ... -
Selection of soybean pods by the stink bugs, Nezara viridula and Piezodorus guildinii
(Oxford Academic Press, 2012-01)Different biological parameters of the stink bugs, Nezara viridula L. and Piezodorus guildinii Westwood (Hemiptera: Pentatomidae), are affected by the developmental stage of the soybean ( Glycine max Merrill) pods they ... -
Soybean Maturity Groups, Environments, and Their Interaction Define Mega-environments for Seed Composition in Argentina
(Wiley, 2006-10)Argentina is the largest soybean [Glycine max (L.) Merrill] meal and oil exporter in the world, with crops covering a 23° to 39° S latitude range, allowing the presence of genotypes from different maturity groups (MG). ... -
Soybean yield, protein content and oil quality in response to interaction of arbuscular mycorrhizal fungi and native microbial populations from mono- and rotation-cropped soils
(Elsevier, 2020-03-01)Two main soil management practices are generally used for soybean production: monoculture (MC) and croprotation (CR). These strategies have different impacts on soil microbial communities. Among them, arbuscularmycorrhizal ... -
