Water table contribution to alfalfa water use in different environments of the Argentine Pampas
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2002)In the Argentine Pampas, although the water table is considered an important source of water supply for the alfalfa crop, it has not been previously quantified.The goal of this study was to estimate ... -
Detecção de genes de resistência a Septoria tritici Rob. em trigo [Triticum aestivum (L.)]
(Escola Superior de Agricultura Luiz de Queiroz, Universidade de Sao Pablo, 2002-06)A mancha foliar provocada por Septoria tritici Rob. é uma das principais doenças do trigo em mais de 50 países, sendo responsável por significativas reduções na produtividade desta cultura. Os objetivos do presente trabalho ... -
Oil quality and sugar content of peanuts (Arachis hypogaea) grown in Argentina : their relationship with climatic variables and seed yield
(ACS Publications, 2003-09)The ratio of oleic to linoleic acids (O/L) and the tocopherol content are important features in determining peanut (Arachis hypogaea) seed shelf life. Soluble carbohydrates are known to be important precursors in roasted ... -
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). ... -
El cultivo de la alfalfa en la Argentina
(Ediciones INTA, 2007)“El Cultivo de la Alfalfa en la Argentina” constituye el más completo y actualizado tratado sobre la alfalfa en los países de habla hispana. Está destinado no sólo a profesionales, estudiantes de Agronomía y Veterinaria y ... -
Environmental effects on seed yield determination of irrigated peanut crops: links with radiation use efficiency and crop growth rate
(Elsevier, 2007-08-12)In Argentina, delayed sowing causes a decrease in seed yield and in radiation use efficiency (RUE) of peanut crops (Arachis hypogaea L.), but it is not known if RUE reduction is mainly due to reduced temperature during ... -
Puesta a punto del método de extracción de adn con CTAB en alfalfa (Medicago sativa L.).
(2008-03-18)Para cualquier tipo de análisis molecular por PCR (Polymerase Chain Reaction) se requiere un buen método de extracción de ADN, que permita obtener tanto una cantidad significativa como una alta calidad del mismo. En base ... -
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 ... -
Water Deficit Effect on the Relationship between Temperature during the Seed Fill Period and Soybean Seed Oil and Protein Concentrations
(Crop Science Society of America, 2009-05-01)Since most soybean [Glycine max (L.) Merr.] seed is processed into meal and oil, there is a growing concern about environmental effects on soybean seed composition. The aim of this work was to investigate how water deficit ... -
