• 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. ...
    • 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 ...
    • 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 ...
