    • Comportamiento de variedades de lino oleaginoso en el sudeste de Buenos Aires, Argentina 

      Bodega, Jose Luis; Di Battista, Emilio; Róvere, Nicolás; Pereyra Iraola, Miguel; Darwich, Gastón Alejandro; Nagore, María Luján; Gallardo, Maricel Andrea; Gieco, Lucrecia Cristina; Martinez, Dionisio Roberto (Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2023-09)
      El cultivo de lino oleaginoso (Linum usitatissimum L.) se realiza en algunos establecimientos del Sudeste Bonaerense y presenta oportunidades de negocio a pesar de no contar con un importante caudal de información actualizada. ...

    • Contribution of honeybees to soybean yield 

      Blettler, Diego César; Fagundez, Guillermina Andrea; Caviglia, Octavio (Springer, 2018-02)
      Despite the economic importance of soybean [Glycine max (L.) Merr.], knowledge on the contribution of entomological pollination on seed yield is scarce. This study estimates the production of soybean resulting from pollination ...

    • Defoliation affects soybean yield depending on time and level of light interception reduction 

      Gregorutti, Viviana Carolina; Caviglia, Octavio; Saluso, Adriana (Southern Cross Publishing, 2012-07)
      Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ...

    • Evaluation of Agricultural Production Systems Simulator as yield predictor of Panicum virgatum and Miscanthus x giganteus in several US environments 

      Ojeda, Jonathan Jesus; Volenec, Jeffrey J.; Brouder, Sylvie M.; Caviglia, Octavio; Agnusdei, Monica Graciela (Wiley, 2017)
      Simulation models for perennial energy crops such as switchgrass (Panicum virgatum L.) and Miscanthus (Miscanthus x giganteus) can be useful tools to design management strategies for biomass productivity improvement in ...

    • Long-term fertilizer application and cover crops improve soil quality and soybean yield in the Northeastern Pampas region of Argentina 

      Fontana, Marianela B.; Novelli, Leonardo Esteban; Sterren, María A.; Uhrich, Walter G.; Benintende, Silvia M.; Barbagelata, Pedro Anibal (Elsevier, 2021-03)
      Long-term improvements in soil quality through cover crops (CC) and fertilizer management may provide resilience for temporal water stresses in cropping sequences based on soybean [Glycine max (L.) Merr.]. The objectives ...

    • Modelling stover and grain yields, and subsurface artificial drainagefrom long-term corn rotations using APSIM 

      Ojeda, Jonathan Jesus; Volenec, Jeffrey J.; Brouder, Sylvie M.; Caviglia, Octavio; Agnusdei, Monica Graciela (2018)
      The Agricultural Production Systems Simulator (APSIM) is a key tool to identify agricultural managementpractices seeking to simultaneously optimize agronomic productivity and input use efficiencies. The aimsof this study ...

    • Nitrogen economy of early and late-sown maize crops 

      Maltese, Nicolás; Melchiori, Ricardo Jose; Maddonni, Gustavo Angel; Ferreyra, J.M.; Caviglia, Octavio (Elsevier, 2018-11)
      Late sowing dates of maize are widely adopted in the Pampas region of Argentina, stabilising grain yields due to a more favourable water balance around flowering. However, late-sown crops are exposed to high soil N ...

    • Optimizing resource productivity in soybean-based sequences through long-term crop intensification 

      Crespo, Cecilia; Novelli, Leonardo Esteban; Wyngaard, Nicolás; Martínez, Roberto Dionisio; Barraco, Miriam Raquel; Gudelj, Vicente Jorge; Barbagelata, Pedro Anibal; Barbieri, Pablo (Elsevier, 2023-10)
      Context: Cropping systems based on a single crop per year, such as soybean monoculture, result in an inefficient use of available resources and low productivity, and are usually related with a negative environmental impact. ...

    • Plant emergence and maize (Zea mays L.) yield across multiple farmers’ fields 

      Albarenque, Susana; Basso, Bruno; Davidson, O.; Maestrini, B.; Melchiori, Ricardo Jose (Elsevier, 2023-10)
      Context: Uneven crop stands result from natural variation in emergence time that is related to soil moisture and temperature, and variation of within-row plant-to-plant distance caused during planting operations. Understanding ...

    • Spatio-Temporal Nitrogen Fertilizer Response in Maize: Field Study and Modeling Approach 

      Albarenque, Susana; Basso, Bruno; Caviglia, Octavio; Melchiori, Ricardo Jose (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 

      Melchiori, Ricardo Jose; Novelli, Leonardo Esteban; Gregorutti, Viviana Carolina; Caviglia, Octavio (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 ...
