Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Maize–soybean intensification alternatives for the Pampas
(2014-06)Cultivating multiple crops as a land use alternative could increase system productivity and sustainability, providing options to soybean monoculture for the Argentinean Pampas. This study evaluates the performance of ... -
Métodos de colocación de fósforo en trigo y maíz bajo siembra directa en el sudeste bonaerense
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)La siembra directa (SD) produce cambios físicos, químicos y biológicos en el suelo que pueden afectar la disponibilidad de P para los cultivos. El uso eficiente de fertilizantes debe combinar factores como dosis, momento, ... -
Mid-Season High-Resolution Satellite Imagery for Forecasting Site-Specific Corn Yield
(MDPI, 2016-10)A timely and accurate crop yield forecast is crucial to make better decisions on crop management, marketing, and storage by assessing ahead and implementing based on expected crop performance. The objective of this study ... -
Monitoring Corn Nitrogen Concentration from Radar (C-SAR), Optical, and Sensor Satellite Data Fusion
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02)Corn (Zea mays L.) nitrogen (N) management requires monitoring plant N concentration (Nc) with remote sensing tools to improve N use, increasing both profitability and sustainability. This work aims to predict the corn Nc ... -
Monitoring corn nitrogen nutrition index from optical and synthetic aperture radar satellite data and soil available nitrogen
(Springer, 2023-08)Nitrogen (N) nutrition index (NNI) is a reliable indicator of plant N status for field crops, but its determination is both labor- and cost-intensive. The utilization of remote sensing approaches for monitoring N, mainly ... -
Nitrogen diagnosis for double-cropped maize
(Elsevier, 2022-10)Double cropping has been proposed as a strategy to promote ecological intensification. In temperate regions, maize (Zea mays L.) could be a viable option for double cropping. However, there is a lack of information regarding ... -
Nitrogen Recovery Efficiency from Urea Treated with NSN Co-Polymer Applied to No-Till Corn
(MDPI, 2018-08-19)Nitrogen (N) rate increases used by many farmers produce a reduced or null effect on N recovery efficiency (RE) by crops. Therefore, management practices to reduce N losses and increase RE are necessary. Co-polymer maleic ... -
Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina
(Elsevier, 2021-01-14)The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ... -
Pérdidas de nitrógeno por volatilización y eficiencia de uso en maíz desde urea aplicada en diferentes momentos
(Ediciones INTA, 2023-06)La volatilización de amoníaco (N-NH3) es una importante vía de pérdida de nitrógeno (N) desde fertilizantes nitrogenados. En tal sentido, existe la necesidad de desarrollar estrategias de manejo que maximicen la eficiencia ... -
Potential for crop production increase in Argentina through closure of existing yield gaps
(Elsevier, 2015-12)Favorable climate and soils for rainfed crop production, together with a relatively low population density, results in 70–90% of Argentina grain production being exported. No assessment to date has tried to estimate the ... -
Pre-harvest strategy for reducing aflatoxin accumulation during storage of maize in Argentina
(Elsevier, 2022-08-27)Maize (Zea mays L.) is an important crop in Argentina. Aspergillus flavus may infect this crop at growing stage and the harvested kernels can be contaminated with aflatoxins (AFs), whose levels may increase during storage. ... -
Predicting maize phenology: intercomparison of functions for developmental response to temperature
(American Society of Agronomy, 2014-12)Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision ... -
Prognosis and diagnosis of sulfur status in maize by plant analysis
(Elsevier, 2019-05)The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ... -
Respiratory distress in Holstein cows fed corn silage: case report
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2023-11-28)An outbreak of respiratory distress was observed in Holstein cows immediately after consuming a new batch of corn-silage, presumably due to the presence of pneumotoxic gases. Signs were observed in 10% of the cows, and ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
