A systems-level yield gap assessment of maize-soybean rotation under high- and low-management inputs in the Western US Corn Belt using APSIM
(Elsevier, 2019-08)Quantifying yield gaps (potential minus actual yield) and identifying management practices to close those gaps is critical for sustaining high-yielding production systems. The objectives of this study were to: 1) calibrate ... -
Biological nitrogen fixation in field pea and vetch: Response to inoculation and residual effect on maize in the Pampean region
(Elsevier, 2020)Including legumes in winter, both as cover crop or for grain harvest, is recommended for avoiding long periods of bare fallow and supplying N for succeeding crops in the rotation. The aims of this study were to i) quantify ... -
Contrasting effects of phosphorus and potassium deficiencies on leaf area development in maize
(Crop Science Society of America, 2018-10)Management of P and K in agricultural systems is similar, since both move mainly by diffusion in soil. In maize (Zea mays L.), radiation capture is a consequence primarily of leaf area formation and senescence, but little ... -
Environmental assessment of maize production alternatives: Traditional, intensive and GMO-based cropping patterns
(2015-10)The evolution of maize production patterns in Argentina is evaluated over the last 25 years to compare costs, benefits, environmental performance and sustainability as well as to identify the main driving sources and ... -
Environmentally sound resource valuation for a more sustainable international trade : case of argentine maize
(2018)This study analyzed costs and benefits for Argentina when trading maize grain. Assigning an appropriate value to traded resources involves a comprehensive assessment of all kinds of sources driving the process, in order ... -
Evaluating a hybrid soil temperature model in a corn-soybean agroecosystem and a tallgrass prairie in the Great plains
(University of Nebraska Press, 2010)Simulation models of soil-related biological processes usually require soil temperature data. Frequently these soil temperatures are simulated, and the soil temperature algorithms cannot be more complicated than the original ... -
Maize nitrogen management in soils with influencing water tables within optimum depth
(Wiley, 2020-10)The central temperate Argentinean region is currently affected by rising water tables, allowing higher and more stable maize yields (Zea mays L) when they fluctuate within optimum depth. However, limited information was ... -
Masas de aire y patrones de circulación asociados a la ocurrencia de deficiencias hídricas severas durante el período crítico de maíz
(Ediciones INTA, 2020-12)En estudios referentes a fenómenos meteorológicos asociados a una región, la Climatología Sinóptica permite analizar las interacciones existentes entre la circulación atmosférica y las condiciones presentes en superficie. ... -
N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ... -
Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(Elsevier, 2020-05)Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ... -
Relación estadística entre los rendimientos de maíz y la ocurrencia de deficiencias hídricas en el departamento Rosario
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2018)Las condiciones ambientales de temperatura, radiación y agua son factores determinantes en el crecimiento, desarrollo y en la producción final del cultivo. El agua disponible es generalmente el principal factor que limita ...
