    • 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. ...

    • Development of the enhanced halsey model to predict equilibrium moisture content (EMC) of sunflower seeds with different oil contents 

      Maciel, Gisele; De La Torre, Diego; Cendoya, Maria Gabriela; Izquierdo, Natalia; Bartosik, Ricardo Enrique (American Society of Agricultural and Biological Engineers, 2018-05)
      Using the right equilibrium moisture content (EMC) relationship is critical for implementing successful aeration strategies and for determining the safe storage moisture content of grains and oilseeds. The oil content of ...

    • Does nitrogen fertilization rate, timing and splitting affect sunflower yield and grain quality? 

      Tovar Hernández, Sergio; Carciochi, Walter; Diovisalvi, Natalia; Izquierdo, Natalia; Wyngard, Nicolás; Barbieri, Pablo; Reussi Calvo, Nahuel Ignacio (Wiley, 2023-02)
      Nitrogen (N) deficiency could have a negative effect on sunflower (Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, and frequency of N fertilization to improve ...

    • Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols 

      Martinez Cuesta, Nicolás; Carciochi, Walter; Sainz Rozas, Hernan Rene; Salvagiotti, Fernando; Colazo, Juan Cruz; Wyngaard, Nicolás; Eyherabide, Mercedes; Ferraris, Gustavo Nestor; Barbieri, Pablo (Taylor and Francis, 2020-11-12)
      Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized to improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, ...

    • Evolution of grain microbiota during hermetic storage of corn (Zea mays L.) 

      Marcos Valle, Facundo; Castellari, Claudia; Yommi, Alejandra Karina; Pereyra, M.A.; Bartosik, Ricardo Enrique (Elsevier, 2021-03-17)
      Respiration of biotic components of the grain ecosystem generates self-modified atmospheres (oxygen reduced and carbon dioxide enriched) during hermetic storage. The effect of temperature, moisture content and modified ...

    • Feed bunk management effects steer performance and behaviour 

      Della Rosa, Maria Milagros; Toffaletti, Jose Rodolfo; Aello, Mario; Burges, Julio Cesar (CSIRO, 2020-03-19)
      Animal performance and behaviour in fattening steers using ad libitum or restricted feed-bunk management were evaluated. High store-capacity self-feeders with weekly recharge were used in ad libitum management (ADLIB), ...

    • Increasing grain yield in bread wheat (Triticum aestivum) by selection for high spike fertility index 

      Pontaroli, Ana Clara; Alonso, Maria Pía; Mirabella, Nadia Estefania; Panelo, Juan Sebastián; Franco, Maria Fiorella; Vanzetti, Leonardo Sebastian; Lorenzo, Maximo (Wiley, 2021-06-28)
      Spike fertility index (SF) has been proposed as a promising selection criterion for increasing grain yield (GY) in bread wheat. Here, changes in GY and related traits after simulated selection (10% intensity) for high SF ...

    • Is the argentine postharvest system ready to handle more and better grains? 

      Abadia, María Bernadette; Urcola, Hernan Alejandro; Ferrari, María Cecilia; Bartosik, Ricardo Enrique (Elsevier, 2019-09)
      This is the first comprehensive study of the grain postharvest system of Argentina with the following objectives: 1) to group the grain elevators according to structural, technological, and insect control characteristics; ...

    • Kernel number response to plant density in tropical, temperate, and tropical × temperate maize hybrids 

      Cerrudo, Diego; Hernández, Mariano; Tollenaar, Matthijs; Vega, Claudia Rosa Cecilia; Echarte, Laura (Crop Science Society of America, 2020-02-07)
      Kernel set response to plant density was examined in terms of physiological processes underlying kernel set in temperate (Te), tropical (Tr), and temperate × tropical (TeTr) maize (Zea mays L.) hybrids. Four field experiments ...

    • Methods to determine nitrogen in sunflower grains 

      Diovisalvi, Natalia; Izquierdo, Natalia; Echeverria, Hernan Eduardo; Garcia, Fernando; Reussi Calvo, Nahuel Ignacio (Asociación Argentina de la Ciencia del Suelo, 2021-12)
      In sunflower, grain oil concentration (OG) determines oil industrial yield and protein concentration (PG) determines the protein of by-products as pellets and meals (PM). There are various methodologies to quantify total ...

    • Nitrogen diagnosis for double-cropped maize 

      Crespo, Cecilia; Martinez, Dionisio Roberto; Wyngaard, Nicolás; Divito, Guillermo; Martinez Cuesta, Nicolás; Barbieri, Pablo (Elsevier, 2022-10)
      Double cropping has been proposed as a strategy to promote ecological intensification. In temperate regions, maize (Zea mays L.) could be a viable option for double cropping. However, there is a lack of information regarding ...

    • Nitrogen Recovery Efficiency from Urea Treated with NSN Co-Polymer Applied to No-Till Corn 

      Barbieri, Pablo; Sainz Rozas, Hernan Rene; Echeverria, Hernan Eduardo (MDPI, 2018-08-19)
      Nitrogen (N) rate increases used by many farmers produce a reduced or null effect on N recovery efficiency (RE) by crops. Therefore, management practices to reduce N losses and increase RE are necessary. Co-polymer maleic ...
