      Fruit load estimation at plot level before harvest is a key issue in fruit growing. To face this challenge, two sampling methods to estimate fruit load in a peach tree orchard were compared: simple random sampling (SRS) ...
    • Comparing efficiency of different sampling schemes to estimate yield and quality parameters in fruit orchards 

      Arnó Satorra, Jaume; Martínez Casasnovas, José Antonio; Uribeetxebarria Alonso de Armiño, Asier; Escolà i Agustí, Alexandre; Rosell Polo, Joan Ramon (The Animal Consortium, 2017-07-16)
      Different sampling schemes were tested to estimate yield (kg/tree), fruit firmness (kg) and the refractometric index (°Baumé) in a peach orchard. In contrast to simple random sampling (SRS), the use of auxiliary information ...
