    • Assessment of nitrogen diagnosis methods in sunflower 

      Tovar Hernandez, Sergio; Diovisalvi, Natalia; Carciochi, Walter Daniel; Izquierdo, Natalia; Sainz Rozas, Hernan Rene; García, Fernando; Reussi Calvo, Nahuel Ignacio (American Society of Agronomy; Estados Unidos, 2021-04-20)
      Nitrogen deficiency can severely limit sunflower (Helianthus annuus L.) grain yield and quality. Our objective was to evaluate N diagnosis methods based on: (a) pre-plant soil nitrate-nitrogen (NO3––N) test (PPSNT) and ...

    • 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 ...

    • 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 ...
