A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize
(Springer Nature, 2021-06-12)The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make ... -
Aerobic stability of whole plant corn silage inoculated with a bacterial inoculant in three maturity stages
(Ediciones INTA, 2021-04)Maturity stage (MS) at harvesting is the most important factor that determines the nutritive value and productivity of corn silage. Once opened, the silage for supplyis exposed to oxygen deterioration due to aerobic microbial ... -
Aggressiveness of fusarium section liseola isolates causing maize ear rot in Argentina
(Edizioni ETS, 2010-03)Developing resistance to species of Fusarium in maize (Zea mays L.) is important to prevent field mycotoxin contamination. Isolates representative of natural conditions need to be identified to maximize selection responses. ... -
An optimized purple corn cob extract as an ingredient for the development of maize-based extrudates with novel characteristics
(Elsevier, 2023-11)Purple corn cobs (PCC) are normally discarded although containing valuable components of potential application in the development of foods and ingredients. Optimum extraction conditions for PCC bioactive compounds were ... -
Aplicación de fósforo en secuencias agrícolas en siembra directa en hapludoles énticos = Phosphorus fertilization in crop sequences in entic hapludolls
(Asociación Argentina de la Ciencia del Suelo, 2016)Los contenidos de fósforo (P) extractable de la mayoría de los suelos de la región pampeana disminuyeron al intensificarse su extracción con cultivos y pasturas. Son frecuentes los sitios con limitaciones en P que requieren ... -
Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
(Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
Assessment of physiological races of Exserohilum turcicum isolates from maize in Argentina and Brazil
(Springer, 2021-02)Northern corn leaf blight (NCLB) is one of the most important diseases in maize worldwide. It is caused by the fungus Exserohilum turcicum, which exhibits a high genetic variability for virulence, and hence physiological ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Changes of starch composition by postflowering environmental conditions in kernels of maize hybrids with different endosperm hardness
(2017-05)Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ... -
Classification of argentine maize landraces in heterotic groups
(Consiglio per la Ricerca in Agricoltura e l'Analisi dell'Economia Agraria, 2012)The genetic diversity of maize (Zea mays L) is a valuable and strategic natural resource that plays a key role in the breeding progress. However, exploitation of genetic variability from landraces has not reached a significant ... -
Climate impacts on crop yields in Central Argentina. Adaptation strategies
(2018-02)The Pampas is among the major agricultural regions in the world; a large proportion of Argentina crop production is originated in this region. The exportation of grain and oil crop represents more than 40% of the total ... -
Comparación de técnicas de análisis multivariado mediante simulación para caracterización de recursos fitogenéticos en función de caracteres susceptibles a interacción genotipo-ambiente
(2018-08)Los Recursos Fitogenéticos se conservan ex situ en bancos de germoplasma. Para que los mismos sean utilizados por los mejoradores deben ser caracterizados y evaluados. En el banco de Germoplasma del INTA Pergamino se realiza ... -
Complementary irrigation in a maize silage double crop using the BAHICU software: a case study in Northern Buenos Aires, Argentina
(2018-04)The north of Buenos Aires province, in the Argentine Humid Pampa, is predominantly an agricultural region, where crops are grown mainly under rain fed conditions. However, in recent decades, complementary irrigation has ... -
Composition and thermal properties of starch in flint maize (Zea mays, L.) kernels: location and crop management effects
(Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Flint maize kernels are processed by the dry-milling industry to produce the flaking grits used thereafter in the corn flakes industry. Flaking-grit yield during milling depends on kernel hardness whereas corn flakes ... -
Contrasting effects of soil type and use of cover crops on nitrogen and phosphorus leaching in agricultural systems of the Argentinean Pampas
(Elsevier, 2024-01)Agricultural systems of the Argentinean Pampas generally use rotations of summer crops under no-tillage and apply fertilization at rates that do not compensate nutrient exports with grain harvest, resulting in negative ... -
Costos ambientales y eficiencia productiva en la producción agraria del partido de Pergamino
(2013)Mediante un modelo de frontera de producción estocástica se analizó el nivel de eficiencia técnica para la producción de soja, maíz y trigo en empresas agropecuarias del partido de Pergamino, Buenos Aires, Argentina. El ... -
Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
