    • Intensive Soybean Management : an Integrated Systems Approach 

      Balboa, Guillermo R.; Stewart, Mike; Salvagiotti, Fernando; García, Fernando O.; Francisco, Eros Artur Bohac; Ciampitti, Ignacio A. (2017)
      Ecological intensification impacted soybean yield, biomass and N uptake. Narrow row spacing, high seeding rate, other best production practices, and balanced nutrition increased partitioning effi ciency for biomass, measured ...

    • Maize nitrogen management in soils with influencing water tables within optimum depth 

      Ruiz, Alejo; Salvagiotti, Fernando; Gambin, Brenda L.; Borrás, Lucas (Wiley, 2020-10)
      The central temperate Argentinean region is currently affected by rising water tables, allowing higher and more stable maize yields (Zea mays L) when they fluctuate within optimum depth. However, limited information was ...

    • N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition 

      Salvagiotti, Fernando; Prystupa, Pablo; Ferraris, Gustavo Nestor; Couretot, Lucrecia Alejandra; Magnano, Luciana; Dignani, Damian; Gutierrez Boem, Flavio Hernán (2017-03)
      Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ...

    • New insights into soybean biological nitrogen fixation 

      Ciampitti, Ignacio A.; Salvagiotti, Fernando (American Society of Agronomy, 2018-08)
      Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ...

    • Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize 

      Carciochi, Walter Daniel; Salvagiotti, Fernando; Pagani, Agustin; Reussi Calvo, Nahuel Ignacio; Eyherabide, Mercedes; Sainz Rozas, Hernan Rene; Ciampitti, Ignacio A. (Elsevier, 2020-05)
      Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ...

    • Nutrient partitioning and stoichiometry in soybean: A synthesis-analysis 

      Tamagno, S.; Balboa, Guillermo R.; Assefa, Yared; Kovács, P.; Casteel, S.N.; Salvagiotti, Fernando; García, Fernando O.; Stewart, W.M.; Ciampitti, Ignacio A. (2017-01)
      On-farm attainable soybean yields are primarily limited by nutrient and water supply. High-yielding soybeans is related to high nutrient uptake. A proposed theoretical framework underpinning yield formation includes plant ...

    • Nutritional and environmental effects on biological nitrogen fixation in soybean: a meta-analysis 

      Santachiara, Gabriel; Salvagiotti, Fernando; Rotundo, José Luis (Elsevier, 2019-07)
      Biological N2 fixation (BNF) and mineral soil absorption are complementary N sources for soybean growth. BNF is sensitive to nutrient and environmental conditions, though a comprehensive synthesis of the studies underlying ...

    • Plant stand, nodulation and seed yield in soybean as affected by phosphate fertilizer placement, source and application method 

      Salvagiotti, Fernando; Barraco, Miriam Raquel; Dignani, Damian; Sanchez, Hector Alfredo; Bono, Angel Alfredo; Vallone, Pedro Salvador; Gerster, Guillermo Raul; Galarza, Carlos Martin; Montoya, Jorgelina Ceferina; Gudelj, Vicente Jorge (2013-11)
      Establishing an optimum plant population at planting is the start-point for assuring seed yield in crops. In addition to plant establishment, the onset of a fully functional nodule system is crucial for nitrogen nutrition ...
