Sequía y calor extremo en el ciclo agrícola 2021/22, impactos en maíces tempranos de Entre Ríos
(Estación Experimental Agropecuaria Paraná, INTA, 2022)Durante las últimas semanas de diciembre de 2021 y las primeras de enero de 2022 se registraron condiciones de severo estrés para los cultivos, dadas por el efecto combinado de la falta de lluvias, elevadas temperaturas ... -
Soil compaction caused by the impact of machinery traffic during corn (Zea mays) harvest = Compactación del suelo causado por el tránsito de maquinarias en la cosecha de maíz (Zea mays)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-06)The aim of this work was to study soil compaction caused by the traffic of two types of combine harvesters and a tractor plus a grain cart with two loading conditions (fully loaded hoppers-empty hoppers) during corn harvest ... -
Spatio-Temporal Nitrogen Fertilizer Response in Maize: Field Study and Modeling Approach
(American Society of Agronomy, 2016)Maize (Zea mays L.) yield and its response to nitrogen (N) are affected by the spatial variability of the interaction between weather, management, and soil properties. The objectives of this study were (i) to evaluate the ... -
Stover quality and soil organic carbon in long-term nitrogen-fertilized maize
(Alliance of Crop, Soil, and Environmental Science Societies, 2014-09)Nitrogen fertilization often increases maize (Zea mays L.) grain yield but reduces the C/N ratio of stover returned to the soil, which may affect the soil organic carbon (SOC) balance. This study evaluated the long-term ... -
The allometric relationships between biomass and nitrogen of vegetative organs affect crop N status in maize at silking stage
(Elsevier, 2023-04)In maize (Zea mays, L.) changes in the partitioning of biomass (W) and nitrogen (N) between organs linked to photosynthetically active tissues, such as leaves (with high N concentration, %N) and organs related to supporting ... -
Variabilidad espacial de la co-limitación de agua y nitrógeno, efecto sobre la eficiencia de uso de agua y nitrógeno en maíz
(Facultad de Agronomía, Universidad de Buenos Aires, 2015-08)El rendimiento en grano del cultivo de maíz (Zea mays L.) se encuentra principalmente limitado por agua y nitrógeno (N), presentando la oferta de ambos recursos una importante variabilidad espacial y temporal. Debido a ...
