(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). ... -
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 ... -
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 ... -
Tocopherol content, peroxide value and sensory attributes in roasted peanuts during storage
(2010-06)The objective of this study was to determine changes in tocopherol content, peroxide value (PV) and sensory attributes from roasted peanuts during storage at 40 °C. There were no differences in tocopherol contents between ... -
Validación de un método de selección para rendimiento en alfalfa basado en la depresión por endocría
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2011)La rápida depresión por endocría en alfalfa obedece a la pérdida de interacciones alélicas intra-locus en plantas tri y tetra alélicas. Éstas podrían identificarse por una prueba de autofecundación y luego combinarse en ... -
Environmental Variation and Correlation of Seed Components in Nontransgenic Soybeans: Protein, Oil, Unsaturated Fatty Acids, Tocopherols, and Isoflavones
(Crop Science Society of America, 2011-03-01)The environment has a significant influence on the expression of traits contributing to soybean nutritional and/or industrial value. The aim of this study was to explore and describe the variability of nontransgenic soybean ... -
Amino acid composition of soybean seeds as affected by climatic variables
(Empresa Brasileira de Pesquisa Agropecuária (Embrapa), 2011-09-12)The objective of this work was to perform a quantitative analysis of the amino acid composition of soybean seeds as affected by climatic variables during seed filling. Amino acids were determined from seed samples taken ... -
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 ... -
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 ... -
Efecto del tipo de desmonte sobre la descomposición de pastos nativos e introducidos en el Chaco Árido de la Argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-04)La dinámica de la descomposición y la liberación de nutrientes a partir de los restos vegetales son procesos clave para la fertilidad edáfica, por lo que resultan adecuados para estimar el grado de sustentabilidad de los ... -
