El objetivo ... -
Photoperiod-sensitivity genes (Ppd-1) : quantifying their effect on the photoperiod response model in wheat
(Oxford University Press, 2019-10)Coupling anthesis date to the most suitable environmental conditions is critical for wheat (Triticum aestivum L.) adaptation and yield potential. Development to anthesis is controlled by temperature and photoperiod. Response ... -
Plaguicidas retenidos en el suelo y perdidos por escurrimiento en dos secuencias de cultivo bajo siembra directa
(Asociación Argentina Ciencia del Suelo, 2019-12)Los plaguicidas utilizados en la agricultura, además de cumplir con su función objetivo de control, se distribuyen en el ambiente y pueden ser retenidos, degradados y/o transformados, o también transportados fuera del lugar ... -
Contenido de elementos traza en argiudoles de la cuenca del arroyo pergamino bajo agricultura continua
(Asociación Argentina Ciencia del Suelo, 2019-12)Los fertilizantes, utilizados continuamente para aumentar los rendimientos de cultivo, conllevan elementos traza (ET) potencialmente contaminantes para el suelo. Los objetivos del trabajo fueron: a) analizar las concentraciones ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
(Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
Nutritional evaluation of dried tomato seeds
(Oxford Academic Press, 2003-01)Two samples of tomato seeds, a by-product of the tomato canning industry were evaluated to determine proximate analysis, amino acid content, and digestibility, TMEn, and protein efficiency ratio. Tomato seeds were also ... -
Evaluación del rendimiento y otros atributos agronómicos en el germoplasma comercial de girasol argentino (1986-2006)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)El mejoramiento genético de girasol en la Argentina resultó en un progreso genético constante para rendimiento en todas las regiones de cultivo de esta especie. En este trabajo, se aplicaron análisis de modelos lineales ... -
Líneas de girasol de la EEA Pergamino
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Se analizaron tres grupos de líneas de girasol (Helianthus annuus) de la EEA Pergamino del INTA. Grupo 1: líneas derivadas de los compuestos P1, P2, P4, PGRK y KLM liberadas en la década del 90. Grupo 2: líneas GP logradas ... -
A first record of bulk atmospheric deposition patterns of major ions in southern South America
(Springer, 2019-09)Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long record of atmospheric ... -
Combining pedigree and genomic information to improve prediction quality : an example in sorghum
(Springer, 2019-07)Selection based on genome-wide markers has become an active breeding strategy in crops. Genomic prediction models can make use of pedigree information to account for the residual polygenic effects not captured by markers. ... -
Interacción genotipo x estación del año sobre caracteres de producción de carne en pollos camperos = Genotype interaction x seasons of the year on meat production characters on campero chicken

Heterogeneity in agricultural land use decisions in Argentine Rolling Pampas : the effects on environmental and economic indicators
(Taylor & Francis Group, 2019-09)Argentine Pampas are one of the major regions in the world for agricultural production. There is a trend towards system simplification in this area, with soybeans being the predominant crop. One major concern of “soybeanization” ... -
Changes in number and weight of wheat and triticale grains to manipulation in source-sink relationship
(Hindawi, 2019-01)The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and ... -
Kernel number and kernel weight determination in dent and popcorn maize
(Elsevier, 2011-02)Yield formation in maize (Zea mays L.) dent hybrids has been directly linked to the rate of plant biomass accumulation and partitioning of assimilates to the developing grain. Maize popcorn genotypes have been studied less ... -
