A time-window within the grain filling period accounted for early leaf senescence in maize under sink limitation
Dosio, Guillermo; Cicore, Pablo Leandro; Rizzalli, Roberto Héctor (Elsevier, 2024-01)In annual crops such as maize, assimilates demand exerted by grains converges with increasing leaf senescence. As sink demand changes as grains growth, leaf senescence could also be affected during the grain filling period. ... -
Cover crops and integrated management reduce pesticide residues in soils and water: Pathways towards cleaner production in Argentine agricultura
Aparicio, Virginia Carolina; Rizzalli, Roberto Héctor; Panaggio, Nestor Hernan; Andrade, Fernando Hector; Costa, Jose Luis (Elsevier, 2026-02)The potential of cover crops and integrated management as a cleaner production strategy for grain systems in the Argentinian Pampas was assessed in this study. A four-year field comparison of conventional farmer practices ... -
Crop intensification with sustainable practices did not increase N2O emissions
Casanave Ponti, Sheila Mailén; Videla, Cecilia; Monterubbianesi, María Gloria; Andrade, Fernando Hector; Rizzalli, Roberto Héctor (Elsevier, 2020-04-15)Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic ... -
Denitrification in a Soil under Wheat Crop in the Humid Pampas of Argentina
Picone, Liliana; Videla, Cecilia; Picaud, Calypso Lisa; García, Fernando Oscar; Rizzalli, Roberto Héctor (Scientific Research, 2014-09)The need to accurately estimate gaseous nitrogen losses from soils is required to have a better understanding of the processes involved as well as soil and environmental conditions, and management practices contributing ... -
Does the photo-thermal environment limit post-flowering maize growth?
Bonelli, Lucas Emmanuel; Cerrudo, Aníbal Alejandro; Olmedo Pico, Belen; Di Matteo, Javier. A; Monzon, Juan Pablo; Rizzalli, Roberto Héctor; Andrade, Fernando Hector (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 ... -
Ecological intensification decreased yield-scaled N20 emissions in a soybean-barley- maize sequence = La intensificación ecológica redujo las emisiones de N2O a escala de rendimiento en una secuencia de soja-cebada-maíz
Casanave Ponti, Sheila Mailén; Videla, Cecilia del Carmen; Rizzalli, Roberto Héctor; Monterubbianesi, María Gloria; García, Fernando Oscar; Ortega, Facundo Miguel; Andrade, Fernando Hector (Asociación Argentina de la Ciencia del Suelo, 2022-12)Agricultural challenge today is to maximize crop production reducing negative environmental impacts by efficiently use of resources and inputs. Objectives: i) to evaluate N2O emissions during a soybean-barley-maize rotation ... -
Maíces tempranos y heladas tardías: efecto de helada y el corte de emparejamiento sobre el rendimiento en grano
Hernandez, Mariano Daniel; Aguirre, Francisco; Veliz, Emiliano Oscar; Rizzalli, Roberto Héctor; Cerrudo, Aníbal Alejandro (Estación Experimental Agropecuaria Balcarce, INTA, 2018)Las heladas tardías han sido siempre una condicionante de la fecha a la que se inicia la siembra de maíces Tempranos. Presentamos un trabajo que lo evaluó el impacto de un corte de emparejamiento sobre el rendimiento de ... -
El maíz y la intensificación sostenible
Caviglia, Octavio; Rizzalli, Roberto Héctor; Andrade, Fernando Hector (MAIZAR, Asociación Maíz y Sorgo Argentino, 2023)Los objetivos del presente capítulo son i) introducir los principales conceptos de intensificación sostenible, sus pilares y prácticas agronómicas, ii) describir los aportes a los pilares de la intensificación sostenible ... -
Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina
Picone, Liliana; Bayer, Cimélio; Videla, Cecilia; Rizzalli, Roberto Héctor; Casanave Ponti, Sheila Mailén; Andrade, Fernando Hector; Garcia, Fernando (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 ... -
Soil respiration response to reductions in maize plant density and increased row spacing (Southeast pampas, Argentina)
Lewczuk, Nuria; Picone, Liliana; Echarte, María Mercedes; Alfonso, Cecilia; Rizzalli, Roberto Héctor; Echarte, Laura (Elsevier, 2024-09)Previous studies have recognized the influence of crop cover and agricultural management on variables (soil temperature, soil moisture, and root biomass) that influence soil respiration. However, despite the influence of ... -
Unidad demostrativa agroecológica Balcarce (UDAB). Fortaleciendo capacidades para una agricultura sostenible
Maceira, Nestor Oscar; Martiarena, Diego Andres; Rizzalli, Roberto Héctor; Jaimes, Florencia; Castaño, Jorge Alberto; Quiñones Martorello, Adriana; Fernandez, María Elena; Galetti, Mario Alfredo; Stefañuk Bahamonde, Francisco José; Natinzon, Paula Carina; Andrade, Fernando Hector; Weyland, Federico; Angelini, Hernán Pablo; Studdert, Guillermo; Villarino, Sebastian; Dominguez, German; Muñoz, Sebastián Darío; Thougnon Islas, Andrea Julieta (Ediciones INTA, 2020-03)La UDAB se puso en marcha en 2017 en el marco de la Red de Agroecología (REDAE) del INTA, contando a su vez con el apoyo del PNNAT 1128034 “Capacitación y soporte técnico en procesos de ordenamiento territorial rural”.
