Años requeridos para la evaluación a campo de cultivares comerciales de trigo pan en Argentina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2022-09)En Argentina, la normativa vigente establece cuatro años de evaluación de rendimiento para cualquier nuevo cultivar comercial de trigo pan. El objetivo de este trabajo fue determinar la cantidad óptima de años de evaluación ... -
Critical period for seed number determination in soybean as determined by crop growth rate, duration, and dry matter accumulation
(Elsevier, 2020-12-13)Seed number (SN) is positively associated with aboveground dry matter (ADM) accumulation in most crop species. In soybean, there are discrepancies among studies relative to the start and end of the critical period for seed ... -
Depth distribution of soil, glyphosate, and aminomethylphosphonic acid (AMPA) properties and analysis of crop yield in six long-term experiments
(Springer, 2023-03-21)Context: Argentina is the third-largest user of pesticides per year, with more than 65% of the herbicide being glyphosate. Glyphosate and aminomethylphosphonic acid (AMPA) have similar properties in terms of environmental ... -
Does the photo-thermal environment limit post-flowering maize growth?
(Elsevier, 2020-07-01)After canopy closure and in the absence of limitations by water or nutrient availability, crop growth rate (CGR) of maize (Zea mays L.) is ultimately constrained by the daily incident radiation and temperature of the ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier, 2020-09)This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ... -
Exploring maize grain yield response to boron fertilization in Mollisols : critical thresholds and predictive models
(Wiley, 2024-05)Background: There are no extractable boron (B) thresholds for maize (Zea mays L.) in Mollisols determined by field calibrations. Aims: Our objectives were to: (1) explore maize grain yield response to B fertilization, (2) ... -
Impacto de las enfermedades foliares sobre variables fisiológicas determinantes del rendimiento del girasol ante diferentes situaciones de cultivo
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)La mancha de la hoja por Alternaria (ALT) y la mancha negra del tallo por Phoma (MNT) son enfermedades foliares endémicas del girasol en Argentina. MNT disminuye regularmente el rendimiento del girasol de alto potencial ... -
Influence of management practices on water-related grain yield determinants
(Oxford University Press, 2023-07-25)Adequate management of N supply, plant density, row spacing, and/or soil cover has proved useful to increase grain yields and/or grain yield stability across years of rainfed crops. We reviewed the impact of these management ... -
Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
(2014)No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations ... -
Revisiting the relationship between nitrogen nutrition index and yield across major species
(Elsevier, 2024-03)Crop nitrogen (N) fertilization diagnoses via the N nutrition index (NNI)-yield relationship have been tested for several crop species, but a cross-species comparison of that relationship has not been performed yet. This ...
